Genetic risk for PTSD varies across different types of trauma

A groundbreaking study reveals that your genes may make you more vulnerable to Post Traumatic Stress Disorder (PTSD) from certain types of trauma-particularly childhood neglect-than from others.

Study establishes foundational landscape of tumor evolution in bladder cancer

A new study published in Nature has established the foundational landscape of tumor evolution in bladder cancer and differences in the cancer subtypes, which could point toward better diagnosis and treatment of the disease.

Norwegian scientists harvest super donor cells to fight diverse diseases

Cells from nine "super donors" are being collected in Oslo. The aim is for these to be used to repair or replace damaged cells, tissue and organs in people suffering from conditions ranging from heart attacks to Parkinson's disease.

Rare cortical neurons actively promote the transition into sleep

What makes the brain fall asleep? For nearly a century, scientists have looked to structures deep within the brain for the answer.

Women use creatine differently from men, survey reveals

A cross-sectional survey of 2,094 current or recent creatine users found that women were more concentrated in shorter-duration use groups than men and reported different supplementation goals, information sources, and knowledge patterns. Women were less likely to cite athletic performance and more likely to cite healthy aging as a goal, while researchers cautioned that the survey design cannot explain why these differences exist.

Nighttime light exposure may alter heart structure and function

Exposure to light during the nighttime is linked to important and potentially harmful changes to the structure and function of the heart, according to a study of more than 11,000 people published in the European Heart Journal today (Thursday).

Tizanidine looked promising early in a migraine trial, but the benefit did not last

A randomized, double-blind, placebo-controlled trial found that low-dose tizanidine did not provide sustained reductions in headache burden over 12 weeks in people with episodic migraine, despite a transient improvement with the 1 mg dose at week 4. Exploratory analyses suggested that smoking and sex may influence tizanidine exposure, while sex-specific efficacy signals remained hypothesis-generating and require confirmation.

Spleen imaging features may reveal coronary artery disease risk

A new study led by investigators from Mass General Brigham reveals that certain features in the spleen hidden within imaging scans may signal a person's risk of coronary artery disease (CAD), suggesting targets for prevention and treatment.

New AI model decodes chemical signals guiding embryonic cell development

As an embryo develops from a small cluster of stem cells, those once "blank slate" cells begin to take on more specialized roles like brain, liver, or muscle cells, and organize themselves into three-dimensional structures such as tissues and organs.

Mitochondrial stress triggers long-term protection against heart damage

Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do so much more-including acting as signaling hubs.

High-energy tissues rely on macrophages to clear cellular waste

The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture), and brown fat (for heat production), each require a lot of energy and make a lot of waste. And that waste needs to be managed.

Semaglutide extended lifespan in older female mice, but that was not the only finding

Late-life semaglutide treatment slowed age-related physiological decline, attenuated multiple molecular hallmarks of aging, and extended median lifespan from 742 to 834 days in aged female mice. The drug reproduced many effects of calorie restriction while providing additional benefits in exploratory behavior, spatial memory, and glucose control, suggesting that some effects extend beyond reduced calorie intake alone.

Targeting KV7 proteins could help delay preterm labor

Scientists have found that targeting a particular group of proteins in the uterus muscle (myometrium) can suppress human uterine contractions in laboratory studies and delay preterm birth in a preclinical model.

Generative AI helps scientists design entirely new RNA transporters

Researchers at Helmholtz Munich and TUM have developed Synthetic Transfer Vehicles (STVs), an entirely new class of RNA transporters.

Scientists develop lab-grown heart tissue model for heart failure

Scientists study the underlying causes of a disease or test new potential drugs in animal models or cells obtained from human biopsy specimens before clinical trials.

Semaglutide extends lifespan and slows physiological aging in healthy mice

A National Institutes of Health (NIH)-funded study has shown that the GLP-1 drug semaglutide extended lifespan in older, healthy mice by tempering the detrimental effects of aging.

Muscle matters: Simple scan could predict heart surgery risks

Around one in four heart surgery patients develop serious lung complications – but a new Adelaide-led study is testing a simple bedside scan that could predict who is most at risk before symptoms appear.

Researchers identify a previously unknown mechanism that can drive cancer cachexia

Researchers at Helmholtz Munich, the Heidelberg Faculty of Medicine at Heidelberg University, the German Center for Diabetes Research (DZD) and the Technical University of Munich (TUM), have identified a previously unknown mechanism that can drive cancer cachexia – a wasting process in the body that primarily affects muscle and fat tissue.

Newly discovered lung immune cells could transform future flu vaccine design

Influenza continues to cause major illness each year in the United States, leading to more than 35,000 deaths annually. Children, older adults, pregnant individuals, people with weakened immune systems, and those with chronic conditions such as heart disease, metabolic disorders, and cancer are especially vulnerable.

The scale told a similar story across three diets. The liver told a different one

In a randomized controlled trial of people with metabolically unhealthy obesity, approximately 10% weight loss improved insulin sensitivity and several cardiometabolic measures across ketogenic, Mediterranean, and very-low-fat plant-forward diets. However, the very-low-carbohydrate ketogenic diet produced larger improvements in hepatic insulin sensitivity and greater reductions in liver fat and several glucose and insulin measures than the higher-carbohydrate diets.
