But they highlight the possibility that, as the epidemic continues, the virus could evolve in ways that would allow it to spread easily among people, experts said.“The flu mutates all the time — that's what, in a sense, the flu does,” said Richard Webby, a flu expert at St. Jude Children's Research Hospital, who was not involved in the work.“The real key would be if we started to see some of these mutations become more widespread,” Dr. Webby said. “This would increase the level of ...

The world watches what happens on American campuses with shock, pride, joy and alarm. Scenes of protests – and arrests of demonstrators – were headline news around the world, from Bogotá to Berlin, from Tehran to Paris.In some countries, including France, students have staged protests of their own, though not with the scale and intensity of those in the United States.Some applaud the protests. Others, especially in countries ruled by authoritarian regimes, see the crackdown as evidence of American hypocrisy on human rights and free speech. Still others see them as the latest sordid chapter in America's ongoing culture wars.In some ways, the protests and the response to them are a Rorschach test for the world: The analysis often offers more insight into local politics than American p...

A landmark antitrust trial against Google ended Friday after a federal judge heard closing arguments, setting the stage for a ruling that could fundamentally shift the power of the tech industry.“The importance and significance of this case is not lost on me, not only to Google but to the public,” Judge Amit P. Mehta said in the final moments of the proceedings Friday.

Soon after their arrival in late December 2020, Covid-19 vaccines turned the pandemic around and paved the way for a return to normality. According to one estimate, they have prevented around 14.4 million deaths worldwide.In a small percentage of people they also produced side effects.Over the course of more than a year, The New York Times spoke to 30 people who said they had been harmed by Covid vaccines. Their symptoms may turn out to be unrelated to the injections. But they — along with more than a dozen experts — believe federal officials aren't doing enough to investigate their complaints.All vaccines carry some risk of side effects. More than 270 million Americans have received about 677 million doses of Covid vaccines, and even rare side effects — occurring in, say, only 0.0...

Rebuilding all the homes destroyed by Israel's military offensive in the Gaza Strip could take until the next century if the pace of reconstruction matches that seen after the 2014 and 2021 wars, according to a United Nations report released Thursday.Citing data from the Palestinian Central Bureau of Statistics, the UN report said that as of April 15, around 370,000 homes in Gaza had been damaged, 79,000 of which had been destroyed.

Prairie voles are stocky, Olympic tunneling rodents that emerge into grassy areas to feast on grass, roots and seeds with their chisel-like teeth, causing migraines in farmers and gardeners.But for Larry Young they were the secret to understanding romance and love.Professor Young, a neuroscientist at Emory University in Atlanta, used prairie voles in a series of experiments that revealed the chemical process for pirouetting the throbbing emotions that poets have tried to put into words for centuries.He died on March 21 in Tsukuba, Japan, where he was helping to organize a scientific conference. He was 56 years old. The cause was a heart attack, said his wife, Anne Murphy.With their beady eyes, thick tails and sharp claws, prairie voles aren't exactly cuddly. But among rodents they a...
