The last time a new drug for Chagas disease was introduced, Richard Nixon was in his first term as U.S. president. Now, in a study published yesterday, researchers unveil a drug that appears to safely eliminate from mice and monkeys the parasites that cause the sometimes-fatal tropical disease. The scientists hope clinical trials of the compound can begin soon and that it will have...
Most of the $280 billion in a new law to strengthen the U.S. semiconductor industry and keep the country ahead of China in technology is a 5-year promise, not a reality. But along with the aspirational spending, the recently passed CHIPS and Science Act commits some $13 billion right now for research and training in microelectronics.

Reconstructing ancient climates is murky business. Cores of sediment or ice contain records of temperatures that date back hundreds of thousands or even millions of years, but typically only near Earth’s surface or in the ocean. Now, by measuring rare oxygen isotopes, a team of geochemists has developed a way to deduce long-ago global temperatures 10 kilometers up in the atmosphere,...
Breathing air high up on the Tibetan Plateau gives most people headaches, but massive yaks have no trouble sprinting through the grassy plains. In a new study, researchers describe a newly discovered type of cell that may help these oxlike animals move so agilely in cold, low-oxygen conditions. Researchers have long known that yaks—as well as some people and...
