Scientists are uncovering why Brazil may be one of the most important yet underused resources for studying extreme longevity. Its highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes .. ...

A brief, intense workout may do more than boost fitness--it could help fight cancer. Researchers found that just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA repair and shut down cancer growth signals. When . ...

A large review of studies suggests that exercise can ease depression about as effectively as psychological therapy. Compared with antidepressants, exercise showed similar benefits, though the evidence was less certain. Researchers found that light to ...

Exercise doesn't just challenge the body; it challenges how the brain interprets effort. Scientists discovered that vibrating tendons before cycling allowed people to push harder without feeling like they were working more. Their muscles and hearts . ...

Bariatric surgery far outperformed GLP-1 weight loss drugs in a new real-world comparison of more than 50,000 patients. Two years after treatment, surgery patients lost about 58 pounds on average, while those using semaglutide or tirzepatide lost ...

Researchers in Japan built a miniature human brain circuit using fused stem-cell-derived organoids, allowing them to watch the thalamus and cortex interact in real time. They found that the thalamus plays a decisive role in maturing the cortex and .. ...

Researchers have reconstructed ancient herpesvirus genomes from Iron Age and medieval Europeans, revealing that HHV-6 has been infecting humans for at least 2,500 years. Some people inherited the virus directly in their DNA, passing it down across .. ...

Researchers have developed a magnetic nanomaterial that can kill bone cancer cells and support bone regeneration at the same time. The material heats up under a magnetic field to destroy tumors, while its bioactive coating helps it bond to bone and . ...

Global cancer cases have surged dramatically, doubling since 1990 and reaching 18.5 million new diagnoses in 2023. Deaths have also climbed to over 10 million a year, with the steepest increases hitting low- and middle-income countries. Without ...

Scientists have discovered that wildfires release far more air-polluting gases than previously estimated. Many of these hidden emissions can transform into fine particles that are dangerous to breathe. The study shows wildfire pollution rivals human ...
