Can Alzheimer's genes predict who becomes a SuperAger?

A study on SuperAgers shows exceptional memory isn't solely due to lower Alzheimer's genetic risk, highlighting the role of biological and lifestyle factors.

This edible flower could do more than brighten a plate

A review of 76 publications finds that pot marigold contains more than 500 reported secondary metabolites, along with natural pigments, antioxidants, and substantial dietary fiber. Early food studies report promising results in yogurt, bread, pasta, and edible oils, but limited product trials and no clinical evidence currently prevent human health claims.

Review finds blueberry and grape polyphenols may improve vascular health

A review of 37 publications found that grape- and blueberry-derived polyphenols were associated with modest improvements in cardiovascular risk markers, particularly endothelial function. However, most studies were small or short-term, frequently tested concentrated products, and measured biomarkers rather than cardiovascular events.

Too little or too much iodine may push immunity off balance

This narrative review finds that adequate iodine supports thyroid hormone signaling, leukocyte metabolism, antioxidant defenses, and antimicrobial activity in humans and domesticated mammals. Both deficiency and sustained excess may impair immunity or promote thyroid inflammation, but precise immune-specific intake thresholds remain uncertain.

Plant-based diets reshape gut microbes to boost healthy metabolites

Plant-based diets are good for you. They promote gut, immune, metabolic and cardiovascular health, in part by cultivating a diverse community of intestinal bacteria.

Scientists uncover hidden brain energy dynamics during REM sleep

Our brain demands a lot of energy compared to our other organs. However, it can also make do when energy supplies are sparse, flexibly performing information processing using what is available.

Blood tests improve Alzheimer's detection in Down syndrome patients

New blood tests that detect early changes associated with Alzheimer's disease are making diagnosis easier and accessible to more patients, since they are less invasive than the brain scans or spinal taps typically used for a definitive diagnosis.

Rare BTK mutation drives resistance to targeted therapies for blood cancer

Scientists at Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, and collaborators have uncovered a rare genetic mutation that enables some blood cancers to evade both approved Bruton tyrosine kinase (BTK) inhibitors and newer BTK degraders, a finding that could help shape the next generation of therapies for patients with chronic lymphocytic leukemia (CLL) and related malignancies.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

Bioresorbable sensor tracks deep-tissue lactate for over 10 days in animals

In animal models, the flexible implant captured local metabolic warning signs before selected systemic measurements and used them to guide earlier resuscitation.

Three key brain regions interact during sleep to support memory formation

Researchers at Kennedy Krieger Institute and Johns Hopkins Medicine have discovered that memory consolidation during sleep depends on coordinated activity among three brain regions and disruptions to this activity can impair memory performance.

St. Jude scientists uncover regulatory mechanism for crucial developmental pathway

St. Jude Children's Research Hospital scientists uncovered a regulatory mechanism for signaling of Sonic Hedgehog (SHH), a pathway essential for embryonic development.

NIH grant funds study on stroke-related urinary incontinence

Urinary incontinence is a common but frequently overlooked consequence of stroke. Now, researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC and Rancho Los Amigos National Rehabilitation Center have received a grant from the National Institutes of Health to investigate the brain changes responsible for these symptoms and develop a more personalized approach to treatment.

Industrial chicken farming drives evolution of foodborne bacteria strains

A new study by the Ineos Oxford Institute for antimicrobial research, University of Oxford, reveals that industrial poultry farming has led to more than 100-fold increase in the movement of Campylobacter, allowing strains that once circulated in wild birds to mix extensively in commercial poultry populations.

New injectable hydrogel accelerates healing of deep wounds

Any minor cut or scrape sets the body's natural healing process in motion. However, deep wounds are far more vulnerable to bacterial infection and the accumulation of harmful molecules called reactive oxygen species (ROS) that damage cells and disrupt normal repair mechanisms.

Wearable fingertip patch tracks Parkinson's medication levels through sweat

Engineers and neuroscientists at the University of California San Diego have developed a soft, wearable fingertip patch that continuously tracks a patient's Parkinson's disease medication levels through their sweat.

Taste preference genes drive overeating and metabolic disease risk

Ever wonder why some people crave sweets while others can take them or leave them? Preliminary findings from a new study suggest that people who carry certain genetic variants associated with a preference for sweet or fatty tastes not only tend to eat more of these foods but also have a higher risk of obesity and type 2 diabetes as a result.
