Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

Physical activity may help restore ease of movement and agility during aging

The brain-chemical surge that comes with running may bolster coordination and speed in the old and young alike, a new study of middle-aged mice shows.

Study compares GLP-1 drug benefits and finds substantial variation in clinical effects

GLP-1 receptor agonists improve glycaemic control and provide renal, metabolic, and selective cardiovascular benefits in people with type 2 diabetes, based on an umbrella review of 17 meta-analyses. However, these agents consistently increase gastrointestinal adverse effects and show important distinctions between class-level outcomes and individual drug effects, particularly for semaglutide.

Machine learning model boosts success of liver transplants from circulatory death donors

There are more candidates on the waitlist for a liver transplant than there are available organs, yet about half the time a match is found with a donor who dies after cardiac arrest following the removal of life support, the transplant must be canceled.

How gut microbes shape sleep: New review reveals microbiome clues to insomnia and apnea

A new Brain Medicine review maps how gut microbes influence sleep disorders, from insomnia and sleep apnea to circadian disruption, via bile acids, neurotransmitters, and immune pathways. The findings highlight gut-driven targets for improving sleep quality through diet, probiotics, and microbiome modulation.

Study finds bright nights raise risk for stroke and heart failure in adults over 40

A large UK Biobank study found that higher night-time light exposure is linked to significantly greater risks of coronary artery disease, stroke, heart failure, and other cardiovascular conditions. The findings suggest maintaining darker nights and adequate daytime light could support heart health.
