Biofortified millet improves toddler gut health without adverse effects

Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes, according to a new study led by researchers at Cornell University's Joan Klein Jacobs Center for Precision Nutrition and Health.

Specialized selenoproteins play critical role in regulating cellular health

A new review highlights the remarkable importance of selenoproteins, a specialized group of molecules that, despite their small size, play a decisive role in shaping cellular fate and maintaining biological balance.

Intertwined cellular processes reshape understanding of diabetes

A deeper understanding of how key cellular processes interact is reshaping perspectives on diabetes and its wide-ranging complications.

Cancer cells exploit liver fat to evade immune system destruction

Liver metastases are among the most common and deadly forms of cancer spread. Now, researchers at VIB and KU Leuven, with international collaborators, have discovered how cancer cells exploit a fatty acid abundant in the liver to evade destruction by the immune system.

Novel drug puts cancer cells under extreme metabolic stress

Cancer cells have a voracious appetite for sugar-using it to fuel their rapid growth. This is why many scientists have tried to develop drugs that block cancer cells' metabolism by cutting off their sugar supply.

Type 2 diabetes linked to more severe menopause symptoms

The type of menopause symptoms, as well as their severity, can differ greatly among women. A number of earlier studies have suggested various reasons for those differences.

Mouse study shows how liraglutide briefly rewires gut bacterial communities

Researchers treated male high-fat-fed mice with liraglutide for 14 days, then tracked fecal bacterial communities after a 7-day washout using 16S rRNA sequencing. Liraglutide shifted the microbiome toward Lactobacillus- and Leptogranulimonas-related taxa while reducing several fermentative taxa, but most changes moved back toward baseline after treatment stopped.

Malaria infection causes permanent damage to the spleen immune cells

Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.

Latest hospital rankings place NYU Langone Health at the very top

NYU Langone Health continues to have the most No. 1-ranked specialties and the most top-10 ranked specialties among medical centers in the United States, according to the rankings released today by U.S. News & World Report.

Researchers suggest a potential therapeutic strategy for muscle loss associated with obesity

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

Restricting select amino acids may mimic protein restriction’s healthy aging benefits

A review finds that restricting protein, particularly methionine, isoleucine, and valine, may improve metabolism and influence key aging pathways, largely in experimental models. Short human studies suggest metabolic benefits, but effects on lifespan remain unknown and restriction may harm people with unmet or increased protein needs.

New analytical strategies can measure thousands of gut microbial proteins

The trillions of microorganisms living in our intestine influence our health, from digestion and metabolism to immunity.

Gut microbiome shifts may begin before Alzheimer’s symptoms appear

A narrative review links reduced SCFA-producing gut bacteria and altered microbial metabolism with Alzheimer’s disease, while early evidence suggests similar changes may appear before cognitive symptoms. Mediterranean, DASH, MIND, and prudent diets are associated with beneficial microbial profiles, but direct evidence connecting diet, the microbiome, and amyloid pathology remains limited.

Daily tomatoes lowered a key marker of liver fat in MASLD trial

An exploratory randomized trial found that 200 g of raw tomatoes plus 50 g of tomato sauce daily for six weeks produced a greater reduction in CAP-defined hepatic steatosis than a tomato-free diet in adults with MASLD. The improvement occurred without major weight or metabolic changes, but larger and longer trials are needed to confirm its clinical significance.

RNA-based therapeutic strategy targets brain pathway behind cancer-associated cachexia

A new path has opened toward stopping cancer-associated cachexia, a devastating complication that gradually wastes patients away.

Daytime cortisol patterns track cognitive decline but not Alzheimer’s disease risk

In 3,895 older adults, moderate daytime cortisol variability was associated with better cognition and slower decline, while the highest daily cortisol exposure was linked to poorer cognition and faster decline. Cortisol patterns differed between Black and White participants, but their relationships with cognition were similar, and none predicted incident Alzheimer’s disease.

Arginine boosts immune defenses against cancer and viral infections

The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes.

New mechanism linked to septic heart injury protection uncovered

Sepsis triggers widespread inflammation, circulatory failure and metabolic stress, and cardiac dysfunction is a common complication associated with sharply poorer outcomes.

Consuming less protein could have greater health benefits and extend lifespan

Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering over 350 papers on protein restriction and aging-publishing July 31 in the Cell Press journal Cell Press Blue-suggests that consuming less protein could have greater health benefits and could, in some cases, extend lifespan.

Researchers propose new framework to define clinical obesity

A new approach to defining obesity could help physicians better determine which patients need more intensive treatment by focusing on the effects of excess adiposity on organs and tissues rather than relying primarily on whether a person meets a set of metabolic risk thresholds.
