Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in stunning detail using only a rotating LED light and simple microscopy equipment. It works on any tissue slide, from fresh samples to those more than a century old, allowing scientists to uncover microstructural changes in disorders like Alzheimer’s and even explore the architecture of muscle, bone, and blood vessels.

Researchers at UC Davis discovered that adding a banana to your smoothie may drastically reduce the absorption of flavanols — powerful compounds linked to heart and brain health. The culprit is polyphenol oxidase (PPO), an enzyme abundant in bananas that interferes with flavanol availability. In experiments, banana-based smoothies cut flavanol absorption by 84% compared to berry-based ones.

ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and producing methane. Using advanced metabolic chambers, researchers measured how diet and gut chemistry interact, showing that methane may signal efficient digestion. The work could lead to personalized diets based on individual microbiomes.

Researchers have created a new iron supplement that merges iron, probiotics, and prebiotics. This “three-in-one” formula restores iron levels while maintaining gut health and preventing inflammation. In mice studies, it normalized hemoglobin and gut bacteria without side effects. The innovation could reshape how anemia is treated.

Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized.

A new brain scan tool shows how quickly your body and mind are aging. It can spot early signs of diseases like dementia, long before symptoms begin. The scan looks at hidden clues in your brain to predict future health.

USC researchers have uncovered a hidden driver behind the early and severe onset of Alzheimer's in people with Down syndrome: iron overload in the brain. Their study revealed that individuals with both conditions had twice the iron levels and far more oxidative damage than others. The culprit appears to be ferroptosis, an iron-triggered cell death mechanism, which is especially damaging in sensitive brain regions.

A newly refined method for measuring the Pace of Aging in population-based studies provides a powerful tool for predicting risks associated with aging, including chronic illness, cognitive impairment, disability, and mortality. The method offers researchers and policy makers a novel approach to quantify how quickly individuals and populations experience age-related health decline.

The body defends itself against pathogens by depriving them of vital iron. However, this strategy doesn't always succeed against Salmonella. Researchers have discovered that these bacteria specifically target iron-rich regions within immune cells to replicate. Their findings on how pathogens evade the immune defense are important for fighting infections.

New research sheds light on an understudied area of science: iron levels in the blood and their relationship to cognitive performance in women transitioning into menopause. The findings are good news for women experiencing brain fog and other symptoms.

Researchers find that certain antioxidant enzymes, called selenoproteins, significantly contribute to fighting cell aging. The team used a gene knockout mouse model to help them study the effects of disrupting selenoprotein synthesis. This knockout negatively impacted hematopoietic stem cells and B cell-lineage immune cells, which was driven by the lack of selenoprotein-mediated fighting of lipid peroxides. These phenotypes mimic what is observed in age-related diseases, emphasizing the importance of selenoproteins in these disorders.

Maternal vitamin D levels in the first trimester were related to both prenatal growth and pregnancy outcomes, according to a new study. Low vitamin D levels during the first trimester of pregnancy were associated with higher rates of preterm birth and decreased fetal length.

Higher intake of heme iron, the type found in red meat and other animal products -- as opposed to non-heme iron, found mostly in plant-based foods -- was associated with a higher risk of developing type 2 diabetes (T2D) in a new study. While the link between heme iron and T2D has been reported previously, the study's findings more clearly establish and explain the link.

Doctors recommend making fruits and vegetables a foundational part of the treatment of patients with hypertension. Diets high in fruits and vegetables are found to lower blood pressure, reduce cardiovascular risk, and improve kidney health due to their base-producing effects. A new study details the findings from a five-year interventional randomized control trial.

Cell damage from oxidative stress is a major underlying cause of age-related cognitive and muscle strength decline. Antioxidants can reduce oxidative stress and prevent age-related health decline. A new study has found that mice administered with a blended antioxidant supplement show significant improvements in spatial cognition, short-term memory, and mitigated age-related muscle decline. The study suggests that blended antioxidant supplements hold promise as a dietary intervention for health issues associated with aging.

A new study finds a complex interplay between diet, genes, and the gut microbiota that could explain why IBD develops.

Our eating habits in industrialized societies are far removed from those of ancient humans. This is impacting our intestinal flora, it seems, as newly discovered cellulose degrading bacteria are being lost from the human gut microbiome, especially in industrial societies.

Natural products have unique chemical structures and biological activities and can play a pivotal role in advancing pharmaceutical science.

In a first of its kind randomized controlled trial an international team of researchers shows that caloric restriction can slow the pace of aging in healthy adults. The CALERIE™ intervention slowed pace of aging measured from participants' blood DNA methylation using the algorithm DunedinPACE (Pace of Aging, Computed from the Epigenome). The intervention effect on DunedinPACE represented a 2-3 percent slowing in the pace of aging, which in other studies translates to a 10-15 percent reduction in mortality risk, an effect similar to a smoking cessation intervention.

The health-benefits of brown rice are well-known and widely advertised. But what exactly confers these excellent properties has been subject to speculation until now. Researchers have recently identified cycloartenyl ferulate (CAF) as the main antioxidant and cytoprotective constituent of brown rice. CAF can protect cells from stress directly through antioxidant effects and indirectly by boosting the production of antioxidants within cells.

Researchers have found new evidence that vitamin D may be metabolized differently in people with an elevated body mass index (BMI). The study is a new analysis of data from the VITAL trial, a large nationwide clinical trial that investigated whether taking vitamin D or marine omega-3 supplements could reduce the risk of developing cancer, heart disease, or stroke.

Researchers have developed a new way to fortify foods with vitamin A, which they hope could help to improve the health of millions of people around the world. In a new study, they showed that encapsulating vitamin A in a protective polymer prevents the nutrient from being broken down during cooking or storage.

Iron is a critical micronutrient for the survival of plants and humans, yet too much iron can also be toxic. An interdisciplinary research team has discovered that the protein PATELLIN2 is not only involved in regulating iron levels in plants. PATELLIN2 is one of a group of proteins that are also involved in the transport of vitamin E in humans. The results are also important for supplying people with iron via plant foods.

The availability of foods based on plant proteins to substitute for meat has increased dramatically as more people choose a plant-based diet. At the same time, there are many challenges regarding the nutritional value of these products. A study now shows that many of the meat substitutes sold in Sweden claim a high content of iron -- but in a form that cannot be absorbed by the body.

Two proteins ensure that cells can take up iron when needed. If both control proteins are switched off in mice, the animals develop severe anemia, as expected. Surprisingly, at the same time a cell type of the innate immune defense, the neutrophils, also dramatically decreases. Iron deficiency, a known defense mechanism against infectious pathogens, is a double edged sword, as it simultaneously curbs the defensive power of an important arm of the innate immune system.

Cystic fibrosis patients who supplement their diet with vitamin C can also derive greater benefit from another antioxidant, vitamin E, resulting in a reduction in damaging inflammation, a study suggests.

Research has found diets rich in highly refined fiber like inulin may increase the risk of liver cancer, particularly in individuals who have a vascular deformity in which blood from the intestines bypasses the liver.

The benefit of dietary fiber isn't just the easier pooping that advertisers tout. Fermentable fiber is an essential source of nutrients that your gut microbes and cells of the intestines need to stay healthy. Study participants who had been eating the least amount of fiber before being fed three different kinds of fiber supplement showed the greatest benefit from supplements, regardless of which ones they consumed.

Machine learning is playing an ever-increasing role in biomedical research. Scientists have now developed a new method of using molecular data to extract subtypes of illnesses. In the future, this method can help to support the study of larger patient groups.

Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a new study. The results lead directly to the idea that modifying the diet has the potential to be a new weapon in the fight against antimicrobial resistance. And this does not require eating some exotic diet, but eating a diverse diet, adequate in fiber, a diet that some Americans already eat.

The health benefits of dietary fiber vary across individuals and may depend on the specific type of fiber and the dose consumed, researchers report.

A new article finds a strong link between the actions of free radicals and free iron in the skin -- a link that causes skin to age prematurely after exposure to the sun. The researchers have also identified antioxidants that can be added to skin products to mop-up the harmful iron, thereby minimizing sun damage.

Researchers have discovered a potential biomarker for Alzheimer's disease diagnosis that may also serve as a therapeutic target. Examining cerebrospinal fluid samples from patients with cognitive impairment ranging from subjective impairment to a diagnosis of Alzheimer's disease, they found a shift in the profile of specialized liquid mediators from pro-resolving to pro-inflammatory.

Researchers evaluated whether dietary fiber intake was associated with a decrease in inflammation in older adults and if fiber was inversely related to cardiovascular disease. The results showed that total fiber, and more specifically cereal fiber but not fruit or vegetable fiber, was consistently associated with lower inflammation and lower CVD incidence. Until now there had been limited data on the link between fiber and inflammation among older adults, who have higher levels of inflammation compared with younger adults.

Researchers have developed a new acoustic fabric converts audible sounds into electrical signals. They designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears hear.

The effect of iron supplementation on skeletal muscle atrophy in cancer patients and sufferers from other wasting diseases has been investigated by scientists who studied causes of these conditions in humans and mouse models. The findings shed light on wasting mechanisms in advanced stage cancer patients, for whom prevalence of devastating skeletal muscle atrophy known generally as cachexia reaches 80 percent.

Researchers found that higher levels of dietary fiber are associated with a reduced risk of developing dementia. In a large-scale study, over 3500 Japanese adults completed a dietary survey and were then followed up for two decades. Adults who consumed more fiber, particularly soluble fiber, were less likely to go on to develop dementia. These findings may relate to interactions between the gut and the brain.

Researchers developed a new blood test to measure the pace of biological aging. Based on an analysis of chemical tags on the DNA contained in white blood cells, called DNA methylation marks, the new test is named DunedinPACE (Pace of Aging Computed from the Epigenome). DunedinPACE is a new addition to a fast-growing list of DNA methylation tests designed to measure aging and contributes value-added over and above the current state of the art.

Approximately 10% of new coronary heart disease cases occurring within a decade of middle age could be avoided by preventing iron deficiency, suggests a new study.

Half of pregnant women who had a simple blood test to check their iron stores had low iron levels, and one in four had severe iron deficiency, according to a new article. But despite how common iron deficiency is, 40% of pregnant women in this large regional study never had their iron levels checked, and women of lower socioeconomic status were less likely to get tested. Researchers said the findings underscore the need to revisit clinical guidelines to ensure that ferritin testing, the standard measure of iron deficiency, is included as a routine part of maternal care and pregnancy health screenings.

Review of a landmark, 1944 study on adequate vitamin C levels leads researchers to challenge the WHO's recommended daily amounts.

Researchers say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals. Their experiments working with mice and fruit flies, however, found that the gene for CaMKII also contributes to an evolutionary tradeoff: increased susceptibility to age-associated diseases, frailty and mortality.

A decade-long study of older women found that tea drinkers had slightly stronger bones, while moderate coffee drinking caused no harm. Heavy coffee intake—over five cups a day—was linked to lower bone density, especially in women who consumed more alcohol. Tea’s benefits may stem from catechins that support bone formation. The researchers say small daily habits could make a meaningful difference over time.

Intermountain Health researchers discovered that customizing vitamin D3 doses for heart attack survivors slashed their risk of another heart attack by 50%. The strategy involved frequent monitoring and dose adjustments to reach ideal vitamin D levels. Traditional studies didn’t track blood levels, missing this critical link.

A study found that daily vitamin D supplements helped slow telomere shortening—the cellular process linked to aging and disease. Researchers believe its anti-inflammatory effects may protect DNA. While results are promising, the ideal dose remains unclear, and experts stress that lifestyle choices still matter most for longevity.

Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed real benefits beyond placebo. With no side effects and strong trial results, the approach could provide a middle ground between painkillers and joint surgery.

Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized.

Radiation therapy, once thought of mainly as a local cancer treatment, is now showing power to awaken the immune system in surprising ways. Researchers discovered that combining radiation with immunotherapy can transform stubborn, unresponsive lung tumors into targets for immune attack—especially those considered “cold” and typically resistant. This happens through a rare and poorly understood effect where immune cells are activated systemically, not just at the radiation site. Patients whose tumors underwent this “warm-up” had significantly better outcomes, revealing a promising new strategy for fighting hard-to-treat cancers.

A gene called SDR42E1 has been identified as a key player in how our bodies absorb and process vitamin D. Researchers found that disabling this gene in colorectal cancer cells not only crippled their survival but also disrupted thousands of other genes tied to cancer and metabolism. This opens the door to highly targeted cancer therapies—by either cutting off vitamin D supply to tumors or enhancing the gene’s activity to boost health. The findings hint at vast possibilities in treating diseases influenced by vitamin D, though long-term impacts remain uncertain.

An analysis of data from a national health survey conducted before the pandemic found that pizza, soup and chicken are some of the main sources of sodium (salt) intake for people in all racial and ethnic groups. The study also showed clear differences among adults based on race and ethnicity.

Sterols are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways. Researchers have used a novel approach to show how they interact with other lipids that help cells self-organize.

The skin microbiome plays an important role in health and disease. Researchers have now substantiated that certain skin bacteria can protect us from the sun's ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin's ability to fine-tune how it responds to UV radiation. The findings demonstrate the ability of the skin microbiome to remodel host immune functions.

New research shows that regular exercise can help maintain Vitamin D levels during the darker months.

Climate scientists reveal that millions of today's young people will live through unprecedented lifetime exposure to heatwaves, crop failures, river floods, droughts, wildfires and tropical storms under current climate policies. If global temperatures rise by 3.5 C by 2100, 92% of children born in 2020 will experience unprecedented heatwave exposure over their lifetime, affecting 111 million children. Meeting the Paris Agreement's 1.5 C target could protect 49 million children from this risk. This is only for one birth year; when instead taking into account all children who are between 5 and 18 years old today, this adds up to 1.5 billion children affected under a 3.5 C scenario, and with 654 million children that can be protected by remaining under the 1.5 C threshold.

Scientists have developed a new type of handheld multi-purpose radiation detector that comprehensively detects all types of ionizing radiation. The device can be used by industrial and medical radiation users, regulatory authorities, the nuclear energy industry, first responders and military users. The technology has been patented and is currently being explored for commercialization.

Drawing inspiration from the tardigrade, researchers developed a new strategy that may protect cancer patients from the side effects of radiation therapy.

Getting at least 30 minutes of daily summer sun in the first year of life may mean a lower relapse risk for children who are diagnosed with multiple sclerosis (MS) later, according to a new study. The study also found if a child's biological mother had at least 30 minutes of daily sun during the second trimester of pregnancy, the child had a lower risk of MS relapses. The study does not prove that sun lowers relapse risk for children with MS, it only shows an association.

Psoriasis is a chronic skin disease that manifests itself mainly with skin symptoms (dryness, itching, scaly skin, abnormal patches and plaques). It affects about 2% of the population and is mediated by an altered immune system response that triggers the proliferation of skin cells. Depending on the severity, there are different therapeutic options (topical medications, phototherapy, systemic drugs, etc.), but some conventional treatments can have harmful effects on patients.

Maternal vitamin D levels in the first trimester were related to both prenatal growth and pregnancy outcomes, according to a new study. Low vitamin D levels during the first trimester of pregnancy were associated with higher rates of preterm birth and decreased fetal length.

The health benefits of sunshine could outweigh the risks for people living in places with limited sunlight, such as parts of the UK, a study suggests. Exposure to higher levels of ultraviolet (UV) radiation in areas with low sunlight was linked to a drop in deaths from cardiovascular disease and cancer, according to the research.

Higher intake of heme iron, the type found in red meat and other animal products -- as opposed to non-heme iron, found mostly in plant-based foods -- was associated with a higher risk of developing type 2 diabetes (T2D) in a new study. While the link between heme iron and T2D has been reported previously, the study's findings more clearly establish and explain the link.

Researchers have developed a novel deep learning algorithm that outperformed existing computer-based osteoporosis risk prediction methods, potentially leading to earlier diagnoses and better outcomes for patients with osteoporosis risk.

Osteoporosis or the weakening of bones makes the aging population vulnerable to fractures and a decreased quality of life. The parathyroid hormone (PTH)-derived peptide -- teriparatide has demonstrated strong bone promoting effects. However, it is also to known to exert bone-resorbing effects. A new study uncovers a novel PTH-inducible target gene -- Gprc5a which suppresses the proliferation and differentiation of 'osteoblasts' or bone-forming cells, and may serve as a therapeutic target in the treatment of osteoporosis.

Healthy adults under the age of 75 are unlikely to benefit from taking more than the daily intake of vitamin D recommended by the Institutes of Medicine (IOM) and do not require testing for vitamin D levels. For children, pregnant people, adults older than 75 years and adults with high-risk prediabetes, the guideline recommends vitamin D higher than the IOM recommended daily allowance.

Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.

Obesity and metabolic disorders are increasingly significant global public health issues. In a novel study, a team of dermatologists evaluated the effect of ultraviolet (UV) exposure on appetite and weight regulation. They found that UV exposure raises norepinephrine levels, decreases leptin levels, and induces the browning of subcutaneous fat, thereby increasing energy expenditure. These results potentially pave the way for new approaches to prevent and treat obesity and metabolic disorders.

The team showed that in mice, DHA effectively reversed osteoporosis-related bone loss.

Researchers have developed a human in vitro model that closely mimics the complexities of radiation-induced lung injury (RILI) and radiation dose sensitivity of the human lung. Using a previously developed microfluidic human Lung Alveolus Chip lined by human lung alveolar epithelial cells interfaced with lung capillary cells to recreate the alveolar-capillary interface in vitro, the researchers recapitulated many of the hallmarks of RILI, including radiation-induced DNA damage in lung tissue, cell-specific changes in gene expression, inflammation, and injury to both the lung epithelial cells and blood vessel-lining endothelial cells. By also evaluating the potential of two drugs to suppress the effects of acute RILI, the researchers demonstrated their model's capabilities as an advanced, human-relevant, preclinical, drug discovery platform.

Researchers have found that women who smoke during pregnancy are 2.6 times more likely to give birth prematurely compared to non-smokers -- more than double the previous estimate. The study also found that smoking meant that the baby was four times more likely to be small for its gestational age, putting it at risk of potentially serious complications including breathing difficulties and infections.

Thousands of people could be spared from a hip fracture each year if a new method to identify the risk of osteoporotic fractures were to be introduced in healthcare. This is the view of the researchers who are behind a new 3D-simulation method.

A new study suggests that extreme dietary habits involving carbohydrates and fats affect life expectancy. Researchers found that a low carbohydrate intake in men and a high carbohydrate intake in women are associated with a higher risk of all-cause and cancer-related mortality and that women with higher fat intake may have a lower risk of all-cause mortality. Their findings suggest that people should pursue a balanced diet rather than heavily restricting their carbohydrate or fat intake.

As life expectancy increases worldwide, age-associated diseases such as osteoporosis are having an increasing impact. Although early detection could help physicians intervene as soon as possible -- when treatment might offer the greatest benefit -- this type of detection is not yet possible with current osteoporosis diagnostic tests. Now, researchers have developed a biosensor that could someday help identify those most at risk for osteoporosis using less than a drop of blood.

Taking higher-than-recommended doses of vitamin D for five years reduced the risk of atrial fibrillation in older men and women, according to a new study.

Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression.

Scientists have uncovered a toxic alliance between Aβ and fibrinogen that may explain how Alzheimer’s disease begins. The two proteins together create stubborn clots that damage blood vessels and spark inflammation in the brain. These effects appear even at very low concentrations and disrupt the blood-brain barrier, paving the way for neurodegeneration. The findings highlight a potential new therapeutic target for early intervention.

Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also efficiently cross the blood-brain barrier and show stability in vivo. This discovery could pave the way for regenerative treatments for Alzheimer’s and related diseases.

Scientists discovered that vitamin D2 supplements can lower levels of vitamin D3, the form the body uses most effectively. Unlike D2, vitamin D3 enhances the immune system’s first line of defense against infections. This raises questions about which type of supplement should be prioritized.

Researchers identified microRNA-93 as a genetic driver of fatty liver disease and showed that vitamin B3 can effectively suppress it. This breakthrough suggests niacin could be repurposed as a powerful new treatment for millions worldwide.

Harvard scientists have uncovered that lithium, a naturally occurring element in the brain, may be the missing piece in understanding Alzheimer’s. Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments.

Researchers discovered that women with Alzheimer’s show a sharp loss of omega fatty acids, unlike men, pointing to sex-specific differences in the disease. The study suggests omega-rich diets could be key, but clinical trials are needed.

Your brain has its own elite defense team — and new research shows these "guardian" cells might be the real battleground for neurological diseases like Alzheimer’s and stroke. Scientists discovered that most genetic risks linked to these diseases act not in neurons, but in the blood vessels and immune cells that form the blood-brain barrier.

A new study suggests a promising alternative to previous attempts to remove the sticky, toxic amyloid beta plaques from brains with Alzheimer's Disease: enhancing the brain's own immune cells to clear these plaques more effectively. The findings could reshape the future of Alzheimer's treatments, shifting the focus from simply removing plaques to harnessing the brain's natural defenses.

Air pollution contributes to nearly 7 million premature deaths each year, and its effects go far beyond the lungs. Breathing in wildfire smoke or automobile-related city smog doesn't just increase the risk of asthma and heart disease -- it may also contribute to brain conditions as diverse as Alzheimer's and autism. Scientists have discovered how a chemical change in the brain -- which can be triggered by inflammation and aging as well as toxins found in air pollution, pesticides, wildfire smoke and processed meats -- disrupts normal brain cell function. Known as S-nitrosylation, this chemical change prevents brain cells from making new connections and ultimately results in cellular death, the team discovered.

Identifying and treating risk factors for depression, anxiety and other psychological health conditions during pregnancy and postpartum may improve short- and long-term health outcomes for both mother and child, according to a new scientific statement.

Declining blood levels of two molecules that occur naturally in the body track closely with worsening Alzheimer's disease, particularly in women. Levels were found to drop gradually, from women with no signs of memory, disorientation, and slowed thinking to those with early signs of mild cognitive impairment. Decreases were more prominent in women with moderate or severe stages of the disease. Declines in men were evident in only one molecule, revealing a disease-specific difference between the men and women.

Researchers have discovered a surprising link between a chronic gut infection caused by a common virus and the development of Alzheimer's disease in a subset of people. It is believed most humans are exposed to this virus -- called cytomegalovirus or HCMV -- during the first few decades of life. According to the new research, in some people, the virus may linger in an active state in the gut, where it may travel to the brain via the vagus nerve -- a critical information highway that connects the gut and brain. Once there, the virus can change the immune system and contribute to other changes associated with Alzheimer's disease. This virus may be a target for antiviral treatments.

Many vitamins are produced in chemical factories, often synthetically, but researchers have succeeded in developing a natural and simple method for producing vitamin B2: by gently heating lactic acid bacteria. This could be a game-changer in developing countries, where many suffer from vitamin B2 deficiency, enabling fortification with B2 directly in local kitchens.

Researchers have unraveled how immune cells called microglia can transform and drive harmful processes like neuroinflammation in Alzheimer's disease.

New research reveals many prenatal vitamins don't contain enough of the nutrients that are essential for a healthy pregnancy, while others contain harmful levels of toxic metals. The study checked the amounts of choline and iodine in nonprescription and prescription prenatal vitamins. The research also checked for toxic metals like arsenic, lead and cadmium. The researchers tested a sample of 47 different prenatal vitamins (32 nonprescription and 15 prescription products) bought from online and local stores where people commonly shop. They then measured the actual amounts of choline and iodine in their lab versus what was on the label and also checked for arsenic, lead and cadmium. They compared their findings with official safety standards within 20% of the claimed amount.

A new study found that, among nearly 775,000 pregnant people in Massachusetts, 31 percent of these individuals had at least one unscheduled emergency visit to the hospital, and 3.3 percent had four or more unscheduled hospital visits. The latter group was nearly 50 percent more likely to experience severe maternal morbidity (SMM), which encompasses a range of complications during labor or childbirth that can lead to poor maternal outcomes such as aneurysms, eclampsia, kidney and heart failure, and sepsis.

Alzheimer's disease may damage the brain in two distinct phases, based on new research using sophisticated brain mapping tools. According to researchers who discovered this new view, the first, early phase happens slowly and silently -- before people experience memory problems -- harming just a few vulnerable cell types. In contrast, the second, late phase causes damage that is more widely destructive and coincides with the appearance of symptoms and the rapid accumulation of plaques, tangles, and other Alzheimer's hallmarks.

The protein 'MIPS' changes its internal structure when it becomes active. Its disordered active centre becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8, and fulfills important tasks in the body. Researchers have succeeded for the first time in observing the protein as it re-structures.

Two new papers by a team of researchers demonstrate that evaluating microRNAs in blood can be used not only to diagnose mild cognitive impairment (MCI) but also, critically, to predict the conversion from MCI to dementia due to Alzheimer's disease.

Scientists in Japan have discovered that a natural compound found in a type of ginger called kencur can throw cancer cells into disarray by disrupting how they generate energy. While healthy cells use oxygen to make energy efficiently, cancer cells often rely on a backup method. This ginger-derived molecule doesn t attack that method directly it shuts down the cells' fat-making machinery instead, which surprisingly causes the cells to ramp up their backup system even more. The finding opens new doors in the fight against cancer, showing how natural substances might help target cancer s hidden energy tricks.

Their hope is one day patients can be provided more personalized risk assessments and referred to specialists for preventive and treatment plans for eye and other diseases.

With human retinas grown in a petri dish, researchers discovered how an offshoot of vitamin A generates the specialized cells that enable people to see millions of colors, an ability that dogs, cats, and other mammals do not possess. The findings increase understanding of color blindness, age-related vision loss, and other diseases linked to photoreceptor cells. They also demonstrate how genes instruct the human retina to make specific color-sensing cells, a process scientists thought was controlled by thyroid hormones.

In a comparative analysis across vertebrates of the many cell types in the retina -- mice alone have 130 types -- researchers concluded that most cell types have an ancient evolutionary history. Their remarkable conservation across species suggests that the retina of the last common ancestor of all mammals, which roamed the earth some 200 million year ago, must have had a complexity rivaling the retina of modern mammals.

According to new research, T cells have a nuclear receptor doing something very odd—but very important—to help them fight pathogens and destroy cancer cells. This receptor, called retinoic acid receptor alpha, is known to control gene expression programs in the nucleus, but it also now appears to operate outside the cell nucleus to coordinate the early events triggered at the cell surface that lead to T cell activation.

For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers have now demonstrated this process directly for the first time using culture cells. Among other things, the study shows that the cells quickly eliminate harmful fatty acids. They refine others into molecules that can be used more effectively. In the long term, this turns the components of palm fat into the building blocks of high-quality olive oil, for example.

For the first time, researchers have developed a form of the omega-3 fatty acid docosahexaenoic acid (DHA) that is capable of crossing into the eye's retina to ward off visual declines related to Alzheimer's disease, diabetes and other disorders.

Researchers have demonstrated that the APOE4 gene variant, which increases risk for Alzheimer's but decreases risk of glaucoma, blocks a disease cascade that leads to the destruction of retinal ganglion cells in glaucoma. Additionally, they showed in mouse models that the death of retinal ganglion cells can be prevented by using medications to inhibit a molecule called Galectin-3, which is regulated by the APOE gene. These findings taken together emphasize the critical role of APOE in glaucoma and suggest that Galectin-3 inhibitors hold promise as a glaucoma treatment.

Scientists have challenged the widespread belief that shift workers adjust to the night shift, using data drawn from wearable tech.

Researchers have identified a gene necessary for the survival of retinal ganglion cells -- a class of neurons located in the retina that are critical for vision.

Animal and cell studies show that as retinal cells die in degenerative eye diseases, they make other cells hyperactive, creating noise that further obscures vision. Tests to prove this in humans are hard to conduct, however. Antabuse, an approved drug used to wean people off alcohol, should tamp down this hyperactivity and conclusively show whether hyperactivity plays a role in humans, potentially driving work to find better drugs to help those with progressive vision loss.

A research group has revealed that amyloid-beta detected in blood is secreted from peripheral tissues (pancreas, adipose tissue, skeletal muscle, liver, etc.) that are sensitive to glucose and insulin.

A ubiquitous protein called sigma 1 receptor, which is known to protect cells from stress, appears key to the function and survival of the neurons most impacted by glaucoma, scientists report.

A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed diet. Because eating without hunger predicts future weight gain, these findings hint at a heightened vulnerability during late adolescence.

Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in stunning detail using only a rotating LED light and simple microscopy equipment. It works on any tissue slide, from fresh samples to those more than a century old, allowing scientists to uncover microstructural changes in disorders like Alzheimer’s and even explore the architecture of muscle, bone, and blood vessels.

Millions face Medicare decisions each year, but many don’t take advantage of tools that can save them money and stress. Insurance marketing often overshadows unbiased options like SHIP, leaving people unaware of better choices. Comparing real costs—not just premiums—can prevent unpleasant surprises, especially when provider networks or drug rules change. New assistance programs for low-income adults offer valuable help for 2026.

Scientists studying young adults with obesity discovered early indicators of brain stress that resemble patterns seen in cognitive impairment. The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low choline levels appeared closely tied to these changes. The results hint that early metabolic disruptions may quietly influence the brain long before symptoms emerge.

Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even “unhealthy” ones, was strongly associated with greater weight loss.

Ultra-processed foods are rapidly becoming a global dietary staple, and new research links them to worsening health outcomes around the world. Scientists say only bold, coordinated policy action can counter corporate influence and shift food systems toward healthier options.

Ultra-processed foods, already known for their links to health problems in adults, are now shown to harm young adults too, disrupting blood sugar regulation long before illness appears. A four-year USC study following 85 participants found that even modest increases in UPF consumption drove up the risk of prediabetes and insulin resistance, two early markers that pave the way for type 2 diabetes.

Almost 20% of packaged foods and beverages in the US contain synthetic dyes, often paired with excessive sugar to attract children. These additives have been linked to behavioral issues, yet remain widespread among major brands like Mars and PepsiCo. Experts criticize the FDA for relying on voluntary reform, contrasting it with Europe’s stricter labeling laws. Growing state-level action offers hope for meaningful change.

Novo Nordisk’s oral semaglutide 25 mg achieved up to 16.6% weight loss in a landmark study, rivaling injectable Wegovy. The pill also improved cardiovascular risk factors and physical activity levels. With a safety profile consistent with existing treatments, experts see it as a breakthrough for patients preferring oral options.

More screen time among children and teens is linked to higher risks of heart and metabolic problems, particularly when combined with insufficient sleep. Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic “fingerprint” in frequent screen users. Experts say better sleep and balanced daily routines can help offset these effects and safeguard lifelong health.

ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and producing methane. Using advanced metabolic chambers, researchers measured how diet and gut chemistry interact, showing that methane may signal efficient digestion. The work could lead to personalized diets based on individual microbiomes.

Weight-loss surgery dramatically outperformed GLP-1 medications in improving longevity and reducing heart, kidney, and eye complications for people with obesity and diabetes. Over 10 years, patients lost far more weight and required fewer medications. Experts say surgery continues to offer survival advantages even in the age of potent obesity drugs.

Scientists discovered that lean pork builds muscle more effectively post-workout than high-fat pork, even with identical protein levels. Using advanced tracking techniques, they found that fat content blunted the body’s muscle-building response. The results contradict previous findings about fattier foods enhancing synthesis, suggesting that food form and processing matter.

Spanish researchers found that combining a calorie-reduced Mediterranean diet with exercise and professional support cut type 2 diabetes risk by 31%. Participants also lost weight and reduced waist size, proving that small, consistent lifestyle shifts can yield major health gains. Experts say this realistic approach could be integrated globally to tackle diabetes and obesity epidemics.

Scientists have uncovered a surprising new way the body can burn energy and stay warm. Deep inside fat tissue, they found a hidden system that helps the body use up calories, even without exercise. By studying mice, researchers discovered that brown fat — the type that keeps us warm — has a backup “heater” that kicks in when needed.

New research shows green tea may help the body burn fat and balance blood sugar. In a study with obese mice, it improved metabolism and muscle health without harming lean animals. Scientists say its powerful plant compounds work together to regulate fat and energy use. The findings hint that green tea could be a natural support for healthy weight management.

A major study from Tübingen found that prediabetic individuals who normalized their blood sugar through healthy habits — even without shedding pounds — cut their risk of type 2 diabetes by 71%. Researchers discovered that improved fat distribution, particularly less abdominal fat, was key. The findings suggest that focusing solely on weight loss may overlook the true drivers of diabetes prevention.

Researchers from Leeds found that overeating is driven more by what people believe about food than by its actual ingredients or level of processing. Foods perceived as fatty, sweet, or highly processed were more likely to trigger indulgence. Surprisingly, the “ultra-processed” label explained almost none of the difference in overeating behavior. The findings suggest that perception and psychology may be more important than packaging or processing.

Researchers found that middle-aged adults, especially women, are far more likely to be addicted to ultra-processed foods than older generations. Marketing of diet-focused processed foods in the 1980s may have played a major role. Food addiction was linked to poor health, weight issues, and social isolation, highlighting long-term risks. Experts warn that children today could face even higher addiction rates in the future.

Daily cocoa extract supplements reduced key inflammation markers in older adults, pointing to a role in protecting the heart. The findings reinforce the value of flavanol-rich, plant-based foods for healthier aging.

Mangos, often dismissed as too sugary, may hold hidden benefits for those at risk of diabetes. A George Mason University study found that daily mango eaters showed better blood sugar control and less body fat than those eating a lower-sugar snack. The results suggest that it’s not just sugar levels, but how the sugar is packaged in whole foods, that matters.

Despite strong evidence that salt substitutes can safely lower sodium intake and reduce high blood pressure, very few Americans use them. A new analysis of nearly 20 years of national health data found that usage peaked at just over 5% and then declined, even among those with hypertension. Researchers say this represents a major missed opportunity to improve heart health, especially since salt substitutes are inexpensive and effective.

Orangutans, humans’ close evolutionary relatives, have developed remarkable strategies to survive in the unpredictable rainforests of Borneo. A Rutgers-led study reveals that these apes balance protein intake and adjust their activity to match food availability, avoiding obesity and metabolic disease. Unlike humans, who often overeat processed foods without adjusting energy use, orangutans switch between fruits, leaves, and even stored body fat depending on the season. Their ability to maintain protein levels and conserve energy during scarcity offers insights not only into their survival but also into healthier dietary habits for people.

Researchers studying over 1,000 children found that omega-3 fatty acids may help protect against myopia, while saturated fats may increase risk. Kids with more omega-3 in their diet had healthier eye measurements linked to slower vision deterioration. In contrast, those with high saturated fat intake showed worse outcomes.

Meal timing shifts with age, and researchers found that eating breakfast later is tied to depression, fatigue, sleep problems, and an increased risk of death. Monitoring when meals are eaten could provide an easy health marker for aging adults.

Scientists are racing to improve weight loss treatments beyond drugs like Ozempic and Wegovy, which are effective but plagued by nausea, bone loss, and weight regain. Tufts University chemists have created a new multi-target compound that goes beyond the usual GLP-1, GIP, and glucagon approaches by adding a fourth hormone, PYY. This “quadruple-action” design aims to deliver weight loss results on par with bariatric surgery—up to 30%—without invasive procedures, and could change the future of obesity treatment.

A Mediterranean diet alone is healthy, but when combined with calorie control, exercise, and support, it cuts type 2 diabetes risk by 31%. The PREDIMED-Plus study followed almost 5,000 participants for six years, making it Europe’s largest nutrition trial. Beyond lowering diabetes risk, participants lost more weight and reduced waist size. Researchers call it clear evidence that small, practical changes can have a big public health impact.

Researchers uncovered that hypothalamic neurons safeguard blood sugar overnight by directing fat breakdown, preventing hypoglycemia during early sleep. This subtle control system may explain abnormal metabolism in prediabetes.

Researchers have created plant-based microbeads that trap fat in the gut, helping rats lose weight without side effects. Unlike current drugs, the beads are safe, tasteless, and easy to mix into everyday foods. Human trials are now underway.

A six-month randomized trial challenges the idea that eating more sweet foods increases a person’s preference for sweetness. Participants on diets with high, low, or mixed sweetness levels showed no changes in their sweet taste preferences, energy intake, body weight, or health markers. The study’s rigorous design suggests sweetness alone isn’t to blame for overeating, and even after the intervention, participants naturally returned to their baseline sweet intake.

Many foods we consume today are ultraprocessed, packed with unhealthy ingredients, and linked to major health risks. As consumption of these foods rises, so do chronic health issues, especially among lower-income groups. Experts are calling for clearer guidelines, better research, and systemic changes to reduce the impact of ultraprocessed foods on public health.

Sunniva Kwapeng struggled with lipoedema, a painful condition causing disproportionate fat accumulation, until finally being diagnosed in her 40s. An NTNU study found that a low-carb diet helped alleviate pain and resulted in more weight loss than a low-fat diet. Though compression garments provided relief, the overall treatment options for this poorly understood condition remain scarce.

Researchers at the Salk Institute have used CRISPR to uncover hidden microproteins that control fat cell growth and lipid storage, identifying one confirmed target, Adipocyte-smORF-1183. This breakthrough could lead to more effective obesity treatments, surpassing the limitations of current drugs like GLP-1.

Cutting calories doesn’t just slim you down—it also reduces cysteine, an amino acid that flips fat cells from storage mode to fat-burning mode. Researchers found that lowering cysteine sparks the conversion of white fat into heat-producing brown fat, boosting metabolism and promoting weight loss in both humans and animal models.

People eating minimally processed foods lost twice as much weight as those on ultra-processed diets, even though both diets were nutritionally balanced and participants could eat freely. This real-world, long-term study revealed that food processing itself—not just nutrients—plays a significant role in shaping body weight and health outcomes.

MIT engineers have developed a tiny implantable device that could revolutionize emergency treatment for people with Type 1 diabetes. The device contains a powdered form of glucagon and can be remotely triggered—either manually or automatically by a glucose monitor—to release the hormone when blood sugar drops too low. This offers a potentially life-saving safety net, especially during sleep or for young children.

Scientists have pioneered a new way to monitor sodium levels in the blood—without drawing a single drop. By combining terahertz radiation and optoacoustic detection, they created a non-invasive system that tracks sodium in real time, even through skin. The approach bypasses traditional barriers like water interference and opens up potential for fast, safe diagnostics in humans.

Fitness trackers often fail people with obesity by underestimating their energy burn, leading to discouraging results and misguided health data. A scientist's frustrating experience in an exercise class with his mother-in-law where her effort wasn t reflected on the fitness leaderboard sparked a breakthrough. His team at Northwestern developed a new open-source smartwatch algorithm that accurately captures energy expenditure for individuals with obesity, rivaling gold-standard lab equipment and paving the way for more inclusive, empowering health tracking.

Intermittent fasting might not be a miracle solution, but it stands shoulder to shoulder with traditional calorie-cutting when it comes to shedding pounds and improving metabolic health. A major new analysis reveals that alternate day fasting may have a slight edge, yet none of the methods alone reached clinically meaningful thresholds for weight loss.

Tufts University scientists are aiming to revolutionize the future of weight loss drugs by engineering a new compound that targets four gut hormones instead of the usual one to three. These next-gen tetra-functional peptides may overcome the limitations of current drugs like Ozempic and Mounjaro especially their nausea, muscle loss, and rebound weight gain.

A team of scientists has identified specialized neurons in the brain that store "meal memories" detailed recollections of when and what we eat. These engrams, found in the ventral hippocampus, help regulate eating behavior by communicating with hunger-related areas of the brain. When these memory traces are impaired due to distraction, brain injury, or memory disorders individuals are more likely to overeat because they can't recall recent meals. The research not only uncovers a critical neural mechanism but also suggests new strategies for treating obesity by enhancing memory around food consumption.

New research reveals a surprising downside to calorie-cutting diets: a link to higher levels of depressive symptoms, especially in men and those who are overweight. Despite popular beliefs that healthy eating boosts mental wellness, real-life restrictive diets may be nutritionally unbalanced, potentially harming emotional and cognitive health.

An analysis of data from a national health survey conducted before the pandemic found that pizza, soup and chicken are some of the main sources of sodium (salt) intake for people in all racial and ethnic groups. The study also showed clear differences among adults based on race and ethnicity.

Researchers find high-fat diets set off metabolic dysfunction in cells, leading to weight gain, but these effects can be reversed by treatment with an antioxidant.

Throwing a little heat on your meal might be an effective strategy for cutting back on calories, according to a new study.

Cravings may not be your enemy after all. A study from the University of Illinois found that dieters who allowed themselves dessert in moderation not only lost more weight but also kept cravings in check long-term. By practicing an “inclusion strategy” — weaving small portions of favorite foods into balanced meals — participants shed nearly 8% of their weight in the first year and maintained most of it during the next.

Feeding the gut acetate, paired with the right Bacteroides bacteria, led mice to shed fat without losing muscle. The combo pushed their metabolism into fat-burning mode, similar to fasting or a keto diet. Tests showed the effect vanished without gut bacteria, proving microbes are essential. Researchers now hope this discovery could inspire new obesity-fighting foods.

Women who ate more fiber and unrefined carbs in midlife were significantly more likely to reach old age free of major diseases, with strong bodies and sharp minds. Meanwhile, diets filled with refined carbs predicted poorer health later in life.

Having school dinners rather than packed lunches could encourage picky eating 13-year-olds to eat a wider variety of foods, according to a new study.

Eating even small amounts of ultra-processed foods—like soda, chips, or packaged cookies—can steadily increase your risk of serious health problems. A massive study reviewing data from over 8 million adults worldwide revealed that each extra 100 grams of these foods per day raises the likelihood of high blood pressure, heart issues, cancer, digestive troubles, and even early death.

A Canadian study of 6,000 adults has found that eating large amounts of ultra-processed foods is tied to obesity, inflammation, and markers of poor heart health. Even after accounting for exercise, smoking, and income, the risks remained, hinting that additives and food engineering may play a bigger role than previously thought.

A massive study of 200,000 people shows that counting the actual number of cholesterol-carrying particles (apoB) predicts heart attack risk far better than the traditional cholesterol test. Add in a second marker, lipoprotein(a), and doctors may soon have a sharper tool to catch hidden risks before it’s too late.

Persistently high blood sugar and insulin resistance significantly increased the risk of worsening functional and structural heart damage during growth from adolescence to young adulthood, a new study shows.

A new study asked three questions about muscle protein synthesis in response to a nine-day diet and weight training regimen: First, does the source of protein -- plant or animal-based -- make any difference to muscle gain? Second, does it matter if total daily protein intake is evenly distributed throughout the day? And third, does a moderate but sufficient daily protein intake influence any of these variables? The answer to all three questions is 'no,' the researchers found.

Forget starving yourself with intermittent fasting — new research shows you may get the same health perks simply by cutting carbs. Scientists at the University of Surrey found that lowering carbohydrate intake, even without slashing calories, improved fat metabolism, reduced blood triglycerides, and helped the body handle high-fat meals better.

Research shows that the biological parents' genes affect the child's insulin function and capacity to regulate blood sugar levels and blood lipids in different ways. Such knowledge may be used to to develop preventive treatments that reduce the child's risk of developing type 2 diabetes and cardiovascular disease.

Over a million people in the UK are living with eating disorders, yet England still has no national strategy to address the crisis. Researchers are urging urgent action, warning that inconsistent care and the struggles of remote treatment are leaving patients behind.

A new study published in The Journal of Nutrition showed higher levels of certain omega-3 fatty acids in the blood are associated with better cognitive performance over time in middle-aged adults at a high risk of developing Alzheimer’s disease.
