Dairy farmers sometimes use additives in their cattle housing to reduce emissions from slurry. Emissions of substances such as ammonia occur when urine and feces mix on the floor of the housing. At the same time, dairy farmers want to increase the fertilizing value of the
Southern Africa has one of the most detailed and elaborate bodies of rock art anywhere in the world, from herds of running antelope to dancing men and humanoid beings with wings, hooves and horns. All are painted with fine brushstrokes or fingers. One thing this art lacks is
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
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
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
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
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
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
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
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
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
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
A superconducting material studied for 40 years has turned out to be far more complex than scientists believed. Advanced 3D imaging revealed a hidden patchwork of crystal structures, with unusually wide boundaries that may weaken superconductivity. The discovery challenges
Scientists have uncovered a surprising new clue to why the Mediterranean diet is so good for the heart, brain, and healthy aging. Researchers at USC found that older adults who closely followed the diet had higher levels of two tiny proteins, humanin and SHMOOSE, produced by
In 1987, biologists captured the last free-flying condor to transfer it to captivity, and the largest flying North American bird species was officially declared extinct in the wild. Today, after decades of coordinated efforts and millions of dollars spent on captive breeding
Raw, grilled, roasted, stuffed—there are many ways to enjoy bell peppers, also called capsicums, sweet peppers or paprika. Bell peppers originated in Central and South America and belong to the nightshade family along with tomatoes and eggplants.
Stainless steel is widely used for its corrosion resistance, but it is not invincible. In environments containing chloride ions, such as seawater, pitting corrosion can occur. These pits often start at tiny particles called inclusions embedded in the steel.
Understanding instabilities and turbulence in plasmas is one of the key challenges across a wide range of plasma research fields, including nuclear fusion, astrophysics and laser-plasma physics. In plasmas, slight disturbances can grow due to instabilities, and energy is
Many topics in astronomy and astrophysics are esoteric. There's not much of a relationship between something like the supermassive black hole at the center of the Milky Way and the life of a regular person going about their business. But the sun is different. Its presence in
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction of the Standard Model of particle physics, its magnetic
Current HIV medicines are effective at suppressing the virus in the blood. However, HIV can remain "asleep" or dormant inside certain immune cells and in the brain. These hidden pockets of virus, called HIV reservoirs, are the main reason HIV cannot be cured with today's
Metallic materials used in extremely cold environments must maintain high strength, ductility and fracture toughness to support applications in aerospace, clean energy, superconducting systems and deep-space exploration. However, traditional alloys often suffer performance
