Elaborate poses, tufts of feathers, flamboyant shuffles along an immaculate forest floor — male birds-of-paradise have many ways to woo a potential mate. But now, by examining prepared specimens at the American Museum of Natural History in New York, scientists have discovered what could be yet another tool in the kit of the tropical birds — a visual effect known …

A federal judge ordered the Trump administration to hold off on a plan that would cut $4 billion in federal funding for research at the nation’s universities, cancer centers and hospitals. The funds disbursed by the National Institutes of Health cover the administrative and overhead costs for a vast swath of biomedical research, some of which is directed at tackling …

With TV cameras pointed at her, Felisa Wolfe-Simon began speaking at NASA Headquarters in Washington, D.C., on Dec. 2, 2010. “I’ve discovered — I’ve led a team that has discovered — something that I’ve been thinking about for many years,” Dr. Wolfe-Simon said. She was at that time a visiting researcher with the U.S. Geological Survey, speaking to a sizable …

The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer boundary has noticeably changed shape over the past few decades. “The most likely thing is the outer core is kind of tugging on the inner core …

The draft was almost ready for submission, due in less than a month. More than 150 scientists and other experts had collectively spent thousands of hours working on the report, a first-of-its-kind assessment of nature across the United States. But President Trump ended the effort, started under the Biden administration, by executive order. So, on Jan. 30, the project’s director, …

The National Academies of Sciences, Engineering and Medicine, or NASEM, is an independent, 162-year-old nongovernmental agency tasked with investigating and reporting on a wide range of subjects. In recent years, diversity, equity and inclusion — collectively known as D.E.I. — have been central to its agenda. But the Academies’ priorities changed abruptly on Jan. 31. Shortly after receiving a “stop …

Since December, astronomers have been carefully studying whether an asteroid between 130 and 300 feet long will impact the Earth in just under eight years. And the odds, overall, seem to be rising. On Jan. 29, the chances of this asteroid (named 2024 YR4) striking our planet on Dec. 22, 2032, were 1.3 percent. Then they rose to 1.7 percent …

An abandoned gunpowder storage shed pokes out from a small mound of earth in what’s now a nature preserve in Northern Ireland. It is the perfect place for a spider: semi-subterranean, cool and dark. But in 2021, a crew working on a BBC nature program found more than an average arachnid lurking there. They spotted a dead spider with a …

Asanda Zondi received a startling phone call last Thursday, with orders to make her way to a health clinic in Vulindlela, South Africa, where she was participating in a research study that was testing a new device to prevent pregnancy and H.IV. infection. The trial was shutting down, a nurse told her. The device, a silicone ring inserted into her …

When Andreas Fichtner unspooled a fiber-optic cable into a deep hole in Greenland’s ice, he wasn’t expecting to discover a whole new way that glaciers move. Even when the cable started sending back data, his first reaction was skeptical. “Rubbish,” Dr. Fichtner, a professor of seismology and wave physics at the Swiss university ETH Zurich, remembers thinking. “Just some electronic …
