Scientists have long struggled to understand how human language evolved. Words and sentences don’t leave fossils behind for paleontologists to dig up. A genetic study published on Tuesday offers an important new clue. Researchers found that, between 250,000 and 500,000 years ago, a gene known as NOVA1 underwent a profound evolutionary change in our ancestors. When the scientists put the …

Louis Pasteur was at his most comfortable when working in his Paris laboratory. It was there that he had some of his greatest scientific triumphs, including experiments that helped confirm germs can cause disease. “Everything gets complicated away from the laboratory,” he once complained to a friend. But in 1860, years before he became famous for developing vaccines and heating …

At the annual gathering in Boston this week of one of America’s oldest scientific societies, the discussions touched on threats to humankind: runaway artificial intelligence, toxic “forever chemicals,” the eventual end of the universe. But the most urgent threats for many scientists were the ones aimed at them, as the Trump administration slashes the federal scientific work force and cuts …

Eleanor Maguire, a cognitive neuroscientist whose research on the human hippocampus — especially those belonging to London taxi drivers — transformed the understanding of memory, revealing that a key structure in the brain can be strengthened like a muscle, died on Jan. 4 in London. She was 54. Her death, at a hospice facility, was confirmed by Cathy Price, her …

Federal research funding to tackle areas like cancer, diabetes and heart disease is lagging by about $1 billion behind the levels of recent years, reflecting the chaotic start of the Trump administration and the dictates that froze an array of grants, meetings and communications. The slowdown in awards from the National Institutes of Health has been occurring while a legal …

Above the shores of prehistoric seas and lakes, pterosaurs roamed the skies. They were feathered creatures that ranged in size from pigeons to planes, and the first vertebrates known to have been able to fly. And for millions of years, they had long tails ending in a prominent flap of skin called a vane. Paleontologists have long wondered about this …

An enduring urban legend has it that blind, albino alligators patrol New York City’s sewers. These mythical crocodilians have become ingrained in the city’s lore, and some New Yorkers even celebrate Alligator in the Sewer Day each February. But in Florida, alligators in the sewers are no myth. The reptiles routinely find their way into municipal drainpipes. In late January, …

Infant mortality increased along with births in most states with abortion bans in the first 18 months after the Supreme Court overturned Roe v. Wade, according to new research. The findings, in two studies published Thursday in the journal JAMA, also suggest that abortion bans can have the most significant effects on people who are struggling economically or who are …

The warnings, on thousands of products sold in California, are stark. “Use of the following products,” one label says, “will expose you to chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.” Now, new research shows the warnings may be working. A study published Wednesday in the journal Environmental Science & Technology found …

The No. 2 official at the National Institutes of Health abruptly resigned and retired from government service on Tuesday, in another sign that the Trump administration is reshaping the nation’s public health and biomedical research institutions. The official, Dr. Lawrence A. Tabak, a dentist and researcher, was long considered a steadying force and had weathered past presidential transitions. In a …
