Review outlines how SIRT3 protein regulates global metabolic disorders

A comprehensive review published in Engineering systematically outlines the regulatory capacity of silent information regulator 3 (SIRT3), a mitochondrial deacetylase termed the "head goose molecule", and its negentropic mechanism for intervening global metabolic disorders including type 2 diabetes, obesity, and steatotic liver disease.

Study links past COVID infection to stronger breathing response after brief arousals from sleep

COVID-19 can leave behind fatigue, breathing difficulties and neurological symptoms that persist long after the initial infection.

Capillaries drive new collateral artery formation after heart blockage

New research in mice challenges a long-standing view of how the heart builds backup blood vessels after a coronary artery blockage, showing that new collateral arteries arise primarily from capillaries rather than existing arteries.

Study shows how prostate tumors rewire metabolism to resist therapy

Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.

New review examines why tetanus remains a global health problem

Tetanus is often considered a disease of the past, remembered mainly through childhood vaccinations and warnings about rusty nails.

More coffee, higher testosterone? This study found a more complicated picture

Higher habitual coffee intake was associated with a leaner body composition, lower circulating branched-chain amino acids, and distinct cardiometabolic patterns in 2,264 middle-aged Finnish adults. Hormonal associations differed by sex, with broader testosterone- and SHBG-related patterns in men and more limited SHBG-related changes in women.

Review reveals how nicotine damages blood vessels and heart health

A review published today in Nature Reviews Cardiology provides the most detailed picture yet of how nicotine damages the cardiovascular system – tracing the biological chain of events from the moment nicotine binds to receptors in blood vessel walls through to the atherosclerotic plaque rupture that triggers heart attacks and strokes.

New AI spots hypertrophic cardiomyopathy obstruction from standard ultrasounds

Mayo Clinic researchers have developed and externally validated an artificial intelligence (AI) model that can identify a potentially significant heart obstruction from routine ultrasound videos without relying on specialized Doppler imaging.

$Pomegranate-derived compound shows promise against preserved ejection fraction heart failure$

Pomegranate-derived compound shows promise against preserved ejection fraction heart failure

A compound produced in the body after eating pomegranates improves heart function by up to 80% in a type of heart failure with limited treatment options.

Weight-loss drug users turn to social media over doctors for advice, Coventry University study finds

Researchers from the UK and Canada found that users of GLP-1 medications - weight-loss drugs such as Ozempic, Wegovy and Mounjaro that help regulate appetite and blood sugar levels - often rely on social media, online forums, friends and family for information about the drugs.

New lightweight knee exoskeleton helps older adults walk more easily

The knee is a key weight-bearing and stabilizing joint in daily locomotion, supporting body weight, maintaining balance, and enabling flexible movement during level walking, ramp ascent and descent, and stair ascent and descent.

Key molecule released during exercise strengthens muscles

Scientists have discovered that a key molecule released during exercise strengthens muscles, improves exercise performance and could be a therapeutic treatment for muscle damage caused by type 2 diabetes.

Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood

Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

Japanese research team named a Milestone 2 Awardee of the XPRIZE Healthspan competition

A research team led by Professor Keisuke Goda of the SiRIUS Institute of Medical Research and Graduate School of Medicine at Tohoku University, together with the Department of Chemistry at the University of Tokyo, has been named a Milestone 2 Awardee of the XPRIZE Healthspan competition - one of the world's largest health research competitions.

Immune signaling pathway protects newborn heart cells from injury

Researchers at the University Hospital of Bonn (UKB) and the University of Bonn have identified a previously unknown signaling pathway in the immune system that helps newborn heart cells survive and regenerate after injury.

What happens to body fat when people follow the Eatwell Guide?

Higher adherence to the UK Eatwell Guide was associated with lower BMI, waist circumference, total body fat, and trunk fat in more than 156,000 UK Biobank participants. The associations persisted prospectively across demographic, physical activity, and genetic-risk groups, supporting the role of diet quality in weight management.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.

Common e-cigarette flavorant may disrupt normal embryo development

Vanillin, a common flavoring chemical in e-cigarettes, may disrupt the normal development of embryos in pregnant women who vape, according to a study published today (Thursday) in Human Reproduction, one of the world's leading reproductive medicine journals.

Finnish study links habitual coffee consumption to healthier body metabolism

Coffee is one of the world's most widely consumed beverages, and previous research has linked its consumption to a lower risk of conditions such as type 2 diabetes and cardiovascular disease.
