Study links better midlife vascular health to nearly 13 more dementia-free years

Rss Feed - Mon, 08/10/2026 - 01:49
A long-term study of 12,409 adults found that a greater burden of diabetes, hypertension, and current smoking in midlife was associated with substantially fewer years lived free of dementia. Adults with none of these risk factors had about 30.1 dementia-free years from age 55, compared with 17.5 years among those with all three, a difference of nearly 13 years.

Single-dose psilocybin shows promise for treatment-resistant depression in NHS trial

Rss Feed - Mon, 08/10/2026 - 01:20
A single 25-mg dose of psilocybin with psychological support was feasible to deliver within an NHS setting and produced large preliminary reductions in depressive symptoms among adults with treatment-resistant depression. The Phase 2 feasibility trial also found the treatment was generally well tolerated, although functional unblinding and expectancy effects mean larger, longer efficacy studies are needed.

New human genome benchmark captures both parental copies with near-perfect accuracy

Rss Feed - Mon, 08/10/2026 - 00:39
Researchers created T2T-HG002, a near-perfect diploid human genome benchmark that is free of detectable errors across 99.4% of the genome and captures both maternal and paternal haplotypes. The benchmark expands coverage into previously excluded genomic regions and provides a new framework for evaluating sequencing reads, assemblies, phased variants, and personalized genome inference.

Simple biological age score flags higher cognitive decline risk in older adults

Rss Feed - Mon, 08/10/2026 - 00:10
A study of 4,818 middle-aged and older Chinese adults found that higher light BioAge was associated with greater risks of cognitive impairment, episodic memory decline, and reduced mental intactness. The simple measure, based on age, creatinine, glucose, and CRP, added modest predictive information but requires further validation before clinical use.

Why pulses could play a bigger role in healthy and sustainable diets

Rss Feed - Sun, 08/09/2026 - 23:46
A narrative review finds that pulses may support gut and metabolic health through their fiber, protein, phytochemicals, and interactions with the gut microbiota, while offering a lower environmental footprint than many animal protein sources. Human evidence is strongest for selected cardiometabolic outcomes, while many microbiome and fermentation-related benefits remain supported mainly by animal and laboratory studies.

Study finds more than half of mapped US parks lie near toxic chemical-reporting facilities

Rss Feed - Sun, 08/09/2026 - 23:11
A nationwide geospatial analysis of 151,366 publicly accessible parks found that 52.6% lay within two miles of at least one industrial facility reporting toxic chemical management to the EPA, while 17.7% had parkland within two miles of a current or former Superfund site. The study mapped proximity rather than contamination or exposure, highlighting locations where targeted environmental assessment and healthier urban planning may be warranted.

Study identifies barriers to equitable pediatric cancer trial participation

Rss Feed - Sun, 08/09/2026 - 23:02
While Black and Hispanic families are enthusiastic about research participation, other provider- and systems-focused factors may influence their involvement in pediatric oncology clinical trials, a UT Southwestern Medical Center-led study has found.

Integrated nanomaterials offer new strategies for cancer immunotherapy

Immune checkpoint inhibitors, cancer vaccines and cellular therapies have reshaped oncology, yet most patients still do not achieve lasting benefit.

PRDM16 regulates the balance between proliferation and maturation in human cardiomyocytes

Understanding how heart muscle cells stop dividing and acquire the characteristics needed to sustain lifelong cardiac function remains one of the greatest challenges in cardiovascular biology.

New USC center seeks answers to sex differences in aging

Women live longer than men in nearly every country in the world, yet they experience higher rates of disability, dementia and many other age-related conditions.

Silencing prefrontal cortex helps mice adopt better strategies

The prefrontal cortex, a brain region long associated with learning more flexible behaviors, can sometimes block the ability to think outside the box, a new study in mice shows.

Targeting small group of brain cells may reduce opioid addiction risk

Rss Feed - Fri, 08/07/2026 - 22:55
Researchers at Duke University School of Medicine are investigating how to keep opioids' pain-relieving benefits while reducing their addictive potential. In a study published in Nature, they report a step toward that goal.

New vaccine strategy targets overlooked regions of malaria parasite

Rss Feed - Fri, 08/07/2026 - 22:47
Malaria kills more than half a million people a year, most of them young children in Africa. Two vaccines are now recommended by the World Health Organization, RTS,S and R21.

Study uncovers molecular trigger behind pyrin inflammation in familial Mediterranean fever

Rss Feed - Fri, 08/07/2026 - 22:36
Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease in which the body's own immune system overreacts to minimal or inappropriate stimuli, producing recurrent attacks of fever and painful inflammation.

Thinning cancer cells' sugar coating could expose tumors to immune attack

Rss Feed - Fri, 08/07/2026 - 22:31
Like spies evading detection through being masters of disguise, many cancer cells are adorned with a copious coat of sugar-derived molecules that throws the proverbial hounds of our immune systems off the scent.

Two-gene interaction reveals metastatic risk in breast cancer

Why do some breast cancer patients face a much higher risk of distant metastasis, while others with seemingly similar disease experience far better outcomes?

Combination therapy overcomes ferroptosis resistance in β-catenin-mutant hepatocellular carcinoma

Rss Feed - Fri, 08/07/2026 - 21:46
The aberrant activation of the mTOR pathway and its crosstalk with other signaling cascades represent key drivers of hepatocellular carcinoma (HCC) progression. mTOR-mediated ferroptosis suppression has been implicated in HCC resistance to chemotherapy.

Human skin chemistry shapes species-specific mosquito attraction patterns

There is no such thing as a universal mosquito magnet. In a new study published in iScience, Florida International University (FIU) researchers pitted 119 human volunteers against three of the world's most dangerous mosquito species and found that not one person was attractive to all three.

Growth hormone therapy improves height after childhood stem cell transplants
