Vaping frequency linked to declining lung function in young adults

Long term vaping in young people may induce persistent changes in lung function, suggest preliminary findings published online in the journal Tobacco Control.

Positive psychology may help young adults build lifelong resilience

For a long time, scientists thought that brain development was an exclusive feature of childhood, but now we understand that the brains of older teenagers and young adults undergo one of the most remarkable reorganizations in human lifetime.

Chronic stress promotes oral cancer through a brain–immune pathway

Chronic psychological stress is increasingly recognized as a risk factor for cancer, but how the brain communicates with the immune system to promote tumors has remained unclear.

Gut microbial metabolites may reshape fat tissue through Wnt pathways

Fat tissue grows in two ways: existing fat cells swell, or progenitor cells spawn new fat cells. When new-cell formation falls behind long-term energy surplus, lipids pile up inside aging fat cells-bringing inflammation, insulin resistance, and fat deposits in the liver and muscle.

‘Forever chemicals’ linked to slightly lower muscle mass in middle-aged women

A study of 551 middle-aged women found that higher blood concentrations of certain PFAS chemicals were associated with slightly lower muscle mass, particularly when researchers examined multiple chemicals together. However, these associations did not correspond to poorer muscle function, and the largely cross-sectional findings could not establish whether PFAS exposure contributes to muscle loss.

Exercise benefits mental health, so why is the genetic evidence so mixed?

A systematic review of 61 Mendelian randomization studies found limited and inconsistent genetic evidence that general physical activity causally improves mental health or cognitive outcomes; 30 studies reported only null or directionally opposite findings. More consistent evidence emerged for aerobic exercise and reduced depression risk, and for physical fitness traits, particularly muscle strength and muscle mass, in relation to better mental and cognitive health, although methodological limitations prevent definitive causal conclusions.

The way food feels in your mouth could change how much you eat

A scientific review examines how food texture and mouthfeel interact with oral sensory receptors, saliva, and brain pathways to influence food preferences, eating speed, appetite, and fullness. The authors suggest that understanding these mechanisms could help develop healthier, more satisfying foods, although their long-term effects on metabolic health require further investigation.

Replacement PFAS chemical still harms developing zebrafish embryos

Publishing in the Journal of Hazardous Materials Advances, researchers from Kyushu University used zebrafish embryos to study the health effects of the PFAS called PFBS (Perfluorobutanesulfonic acid), a substitute PFAS thought to be safer than traditional compounds.

Experimental cell therapy helps ordinary skin mimic tough palm tissue

In a phase I clinical trial funded by the National Institutes of Health and the Maryland Stem Cell Research Fund, Johns Hopkins Medicine researchers say they have partially transformed ordinary human skin cells into volar skin - the durable skin found exclusively on the palms and soles that resists friction and pressure.

Blocking serotonin receptors makes eye cancer cells sensitive to drugs

By studying G protein–coupled receptor (GPCR) signaling in a range of uveal melanoma cell lines, Jenna Aumiller and colleagues have discovered a way to make these cells more sensitive to compounds that inhibit cancer-linked (or oncogenic) signaling pathways.

Breakthrough RNA blood test identifies hidden ovarian cancer warning signs

Hoag researchers announced a first in the world discovery of a molecular warning signal in the blood that identifies serous tubal intraepithelial carcinoma (STIC), an early, precancerous stage of high-grade serous ovarian cancer (HGSOC).

Experimental drug targets tumor barriers to unlock cancer-killing T cells

Many solid tumors, including many cancers of the pancreas, breast, brain and lung, protect themselves with a dense wall of scar-like tissue.

Can psychedelics help treat cancer beyond easing end-of-life fear?

A new peer-reviewed review in Psychedelics opens on a strange fact, gathered from existing laboratory studies rather than new experiments: a brain tumor can learn to eavesdrop.

Precision nutrition shifts the focus from calorie cuts to quality

"Eat less, live longer" has a firm footing in the laboratory: dietary restriction extends lifespan across species, from yeast to mammals.

Mogrify to present preclinical proof-of-concept data for first-in-class retinal in vivo reprogramming therapy

Mogrify Limited (Mogrify®), a regenerative medicine company developing a novel class of in vivo reprogramming therapies, today announced it will present preclinical proof-of-concept data at FLORetina-ICOOR 2026.

UCSF launches global study tracking real-world psychedelic experiences

Most psychedelic experiences don't happen in research labs. To better understand their effects, UC San Francisco scientists are going where the experiences are and launching a global study to track what psychedelics do to people's brains, bodies and well-being.

NIH grant supports research into PFAS effects on mosquitoes

Kennesaw State University researcher Andrew Haddow has received a three-year grant from the National Institutes of Health (NIH) worth $517,956 to study the effects of per- and polyfluoroalkyl substances (PFAS), or "forever chemicals," on mosquitoes.

New biomarker may extend detection window for date-rape drug GHB

Gamma-hydroxybutyrate (GHB) can be consumed as a recreational drug or administered secretly to knock victims out.

Repeat thieves show impaired ability to learn from consequences

Theft is almost universally considered an exploitative behavior. The conventional view underlying judicial systems is that the act of taking resources from others without offering compensation stems from moral and personal failings.

Could eating more mushrooms help protect your brain as you age?

A review of existing research suggests that ergothioneine, a natural antioxidant found primarily in mushrooms, may protect brain cells against oxidative stress, inflammation, and damage associated with Alzheimer's and Parkinson's diseases. Although laboratory and animal studies show promising neuroprotective effects, human evidence remains limited, and larger clinical trials are needed to determine whether supplementation can prevent or slow neurodegeneration.
