Researchers have developed a revolutionary microscope that uses an incredibly powerful laser to make previously invisible cellular structures easier to see. The technology dramatically improves image clarity, allowing scientists to examine small ...

Your morning coffee may be packing more calories than you realize, and sugar isn't the biggest reason. A study of 30,000 Americans found that non-dairy creamer has overtaken sugar and milk as the leading source of added coffee calories, helping drive ...

Scientists have discovered why common marmosets have unusually small, smooth brains despite starting development much like other primates. The secret lies in subtle changes to brain-building cells that slow neuron production, revealing new clues ...

A natural compound extracted from a medicinal plant has shown surprising promise against rheumatoid arthritis. In rats, it reduced joint swelling, protected cartilage, and calmed the immune responses responsible for chronic inflammation. Scientists . ...

A simple, steroid-free procedure could offer lasting relief for people struggling with carpal tunnel syndrome, potentially helping them avoid surgery. In a clinical trial involving 63 patients, researchers found that ultrasound-guided hydrodissection ...

Researchers analyzing nearly 150,000 Reddit posts uncovered unexpected symptom reports linked by users to unapproved versions of retatrutide, including increased appetite, sleep disturbances, and elevated heart rates. The findings differ from ...

A massive study of more than 460,000 Americans found that ultra-processed foods were not associated with increased colorectal cancer risk overall, challenging a widely held assumption. While processed meat was linked to higher cancer incidence, ultra ...

Scientists have uncovered an unexpected danger lurking inside cells: too much RNA can damage the structures responsible for producing energy. A new study found that excess RNA, including the normally essential messenger RNA (mRNA), can directly ...

A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts' hearts adapted to months of ...

Scientists have turned blood cells from an 80-year-old into neural stem cells with a molecular age of less than 20, effectively reversing more than 60 years of cellular aging in the laboratory. The discovery offers a new way to investigate how cells ...
