A stranger’s face can hold a cow’s attention longer than a familiar handler’s, video tests suggest, offering clues to how cattle recognize the people around them. When cows watched videos of people, they looked longer when the face on screen matched the voice they heard. The finding suggests that these highly social animals, which live […]

Bigger animals generally have bigger body parts, but new research reveals that certain ants defy this biological rule. In the insect world, bigger bodies usually come with bigger body parts. But some ants break this rule in an unexpected way. A massive soldier ant, equipped with an oversized head and powerful jaws, can have smaller […]

Scientists have discovered distinct bacterial patterns in the saliva of patients with a deadly form of esophageal cancer. Bacteria living in the mouth may hold clues to a deadly form of esophageal cancer that often goes undetected until treatment options are limited. Researchers in South Africa have identified distinctive bacterial patterns in patients’ saliva, raising […]

Researchers uncovered how a high-cholesterol diet weakens the liver’s defenses and lowered LDL in mice by blocking the pathway, pointing to a potential new use for a shelved heart failure drug. A diet high in cholesterol can gradually weaken the liver’s ability to remove harmful cholesterol from the blood. Cholesterol-related heart disease remains the leading […]

New compounds have overcome a longstanding challenge by directly targeting β-arrestins, proteins that regulate cellular signals, providing laboratory tools that could help guide more precise treatments with fewer side effects. A drug can hit its intended target and still have its effects cut short. That’s because cells have built-in molecular brakes that dial down signals […]

Solar grazing is helping sheep farmers expand their businesses, opening opportunities for rural jobs, new investment, and stronger agricultural supply chains. Sheep can feed on the vegetation growing around solar panels while farmers get paid to keep it under control. Too few sheep may leave farmers with grass they still need to mow, while heavier […]

Nearly identical butterflies share the same tropical forests, yet scientists still cannot fully explain how they recognize their own kind. When Andrés Orellana found caterpillars stripping the leaves from a Cecropia sapling in Venezuela, they had the familiar black bodies and yellow spines of Colobura butterflies. None, however, had the cream-colored markings seen in the […]

Ancient tooth proteins raise the possibility that Homo naledi, an extinct human relative, reserved a burial site for females, hinting at complex customs once thought unique to modern humans. For more than a decade, researchers have wondered why the adult fossils in South Africa’s Dinaledi Chamber look so much alike. The remains of Homo naledi, […]

Chemicals that disrupt hormones may leave a molecular “scar” that could someday help identify people at higher risk of breast cancer, research in human breast tissue models suggests. People are typically exposed to several chemicals at once, including endocrine-disrupting chemicals that can interfere with the body’s hormones. Scientists have increasingly questioned whether these exposures contribute […]

Scientists have uncovered new clues about the evolution of a rare, deadly Brazilian virus that has circulated largely undetected for more than a century. A rare and deadly virus went undetected in Brazil after genetic changes allowed it to escape existing laboratory tests. Scientists investigating two fatal infections have now identified the mutations responsible, developed […]
