Brisk walking for just 15 minutes a day cuts death risk in low-income adults, study shows

Fast walking for as little as 15 minutes per day was linked to a nearly 20% reduction in mortality among predominantly Black and low-income American adults. Slow walking showed minimal benefit, but prolonged slow walking reduced the risk of death from ischemic heart disease.

E-scooter riders are three times more likely than cyclists to end up in hospital, study shows

Stand-up electric scooter riders in Helsinki are over three times more likely than cyclists to sustain injuries requiring emergency care, with head trauma and alcohol use significantly more common in scooter crashes. Helmet use among scooter riders remains exceptionally low.

CPADS enables comprehensive analysis of drug resistance across 44 cancer types

CPADS integrates data from the Gene Expression Omnibus (GEO), The Cancer Genome Atlas (TCGA), and the Genomics of Drug Sensitivity in Cancer (GDSC) databases, encompassing over 29,000 samples across 44 cancer types and involving 288 drugs. It provides five main analysis modules: differential expression analysis, correlation analysis, pathway analysis, drug analysis, and gene perturbation analysis.

Infant brain activity shows faster maturation after general anesthesia

New research published today in Proceedings of the National Academy of Sciences (PNAS) finds that prolonged and/or repeated exposure to gamma-aminobutyric acid (GABA) anesthetic agents (sevoflurane, propofol) for infants in the first two months of life resulted in an accelerated maturation of brain electrical activity patterns evoked by visual stimuli when recorded at 2-5 months of age, compared to infants who did not have early general anesthesia exposure.

Thalamic feedback pathway found to tune sensory perception

The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability.

Respiratory infections can reactivate dormant breast cancer cells

Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors.

Most US adults have older heart age than actual age

Most U.S. adults have a "heart age" several years older than their chronological age - sometimes by more than a decade.

Promising new treatment helps the immune system attack and destroy liver tumors

Liver cancer cells thrive on fat, posing a serious risk of cancer diagnosis for millions of people living with fatty liver disease.

Harnessing the power of gut bacteria to enhance cancer immunotherapy effectiveness

A comprehensive new review reveals both the promise and challenges of using fecal microbiota transplantation (FMT) to enhance cancer immunotherapy effectiveness.

New high-selectivity nanozyme enables rapid and visible disease diagnostics

To enable early diagnosis of acute illnesses and effective management of chronic conditions, point-of-care testing (POCT) technology—diagnostics conducted near the patient—is drawing global attention.

New insights reveal how Candida albicans settle and persist in the gut

About 80% of people have the fungus Candida albicans in their gut. Although most of the time it persists unnoticed for years causing no health problems, C. albicans can turn into a dangerous microbe that causes serious diseases in many organs, including the urinary tract, lungs and brain.

Intratumoral microbial metabolites shape the tumor microenvironment and impact immunotherapy

The tumor microenvironment (TME) represents a highly complex system that encompasses cellular components (such as cancer cells, stromal cells, and immune cells) and non-cellular components (such as blood vessels and signaling molecules).

Canadian scientists trap gut microbe fuel to improve blood sugar and liver health

A team of Canadian scientists has discovered a surprising new way to improve blood sugar levels and reduce liver damage: by trapping a little-known fuel made by gut bacteria before they wreak havoc on the body.

PD-1 helps guide immune memory cells to the skin early during infection

Weill Cornell Medicine researchers have discovered that PD-1—a molecule best known for putting the brakes on immune cells—also plays a critical role in helping T cells become long-term immune defenders in the skin.

Researchers classify how specific genetic mutations correspond to rare disorders

The NF-κB signaling pathway plays a pivotal role in how our bodies fight infection, heal, and regulate inflammation. At the heart of this pathway is the NEMO protein, encoded by the IKBKG gene.

Innovative nanopore system enables controlled DNA unzipping

DNA holds the instructions that make us who we are. If we want to read those instructions, say to understand our predisposition to genetic disorders, we need to carefully 'unzip' DNA's iconic double-helix structure.

Immune cells migrate from the gut to breast during pregnancy and lactation

Of the 3.6 million babies born in the United States each year, around 80 percent begin breastfeeding in their first month of life.

Vegan teens exercise more often than meat-eating peers, study finds

A nationwide Austrian study of nearly 9,000 teens reveals distinct health behaviors and motivations among vegetarian, vegan, and omnivorous students. Vegan and vegetarian youth are more likely to report higher fruit, vegetable, and activity levels, but still fall short of daily exercise targets.

Study debunks "No Nut November" claims: Abstinence shows no health benefits or harms

A new study in The Journal of Sexual Medicine found that participating in “No Nut November”, a month-long abstinence challenge, had no measurable effect on sexual well-being. The only significant difference was that participants reported higher sexual flexibility, likely reflecting a pre-existing trait.
