Missing blood pressure medication could mean losing much of its protection against heart attacks and strokes, according to an analysis of more than 91,000 people. Patients who consistently took their medication experienced an 11% reduction in major cardiovascular events, while those who missed too many doses saw little or no measurable benefit.
A major new study reveals that drinking just two alcoholic beverages a day is associated with a 1 in 25 lifetime risk of death from alcohol-related causes, challenging the idea that moderate drinking is harmless. Researchers also found no significant overall health benefits from alcohol, with risks rising as consumption increases.
Astronomers have discovered three actively feeding black holes inside a single galaxy more than 12.5 billion light-years away, revealing a remarkable scene from the universe’s infancy. Two of the black holes are separated by just 620 light-years and are expected to eventually merge, while a third lurks farther away. One weighs an astonishing 80 million suns, and another is growing faster than conventional theories predict.
The most comprehensive record yet of carbon dioxide stored underground through geological carbon dioxide storage has been published today, revealing that 43.6 million metric tons were sequestered in 2024 alone—a new annual record—and that 421.7 million metric tons have now been stored in the past three decades.
Millions of years after animals first conquered land, some took an extraordinary evolutionary U-turn and returned to the water. Using machine learning and thousands of fossil measurements, Yale scientists have uncovered surprising clues about which prehistoric creatures truly became aquatic. Their findings suggest that Spinosaurus spent most of its life underwater, while some ancient marine reptiles previously thought to be fully aquatic actually spent considerable time on land.
Scientists have discovered how pancreatic cancer cells continually reshape their genetic makeup to become more aggressive, spread, and evade treatment. In laboratory experiments, blocking a key gene reversed some of these dangerous changes, revealing a potential new way to fight the deadly disease.
Inspired by the ability of sea cucumbers to change the stiffness of their bodies, University of Waterloo researchers have developed a gel that could one day help repair damaged tendons and other soft tissues without leaving permanent material behind.
A common, inexpensive medication could hold an unexpected clue to preventing dementia. Researchers found that older adults with a specific genetic profile had a 70% lower relative risk of dementia when taking low-dose aspirin, even though previous studies found no overall protective effect. The discovery suggests that genetics could help explain why some people benefit while others do not.
With the midterms fast approaching, communicating just the right message has been top of mind on all sides of the political aisle
For nearly a century, people in distant parts of the world have reported a bizarre experience after eating certain wild mushrooms: seeing dozens or even hundreds of tiny, colorful humans moving through the real world. Now, scientists have identified a mushroom species, Lanmaoa asiatica, responsible for these extraordinary hallucinations in China and the Philippines.
A cannabis-derived ingredient commonly found in sleep gummies may be more habit-forming than previously thought, with new research showing that repeated exposure caused tolerance and withdrawal symptoms in mice. Scientists warn that CBN may carry risks similar to THC, although its long-term effects in humans remain largely unknown.
Astronomers have uncovered evidence of a bizarre, potentially historic discovery: the first moon ever detected beyond our Solar System. Unlike familiar moons, this mysterious object is at least as massive as Jupiter and orbits a brown dwarf, which itself circles a star. The unusual arrangement challenges traditional definitions of planets and moons, leaving scientists unsure what to call it.
