Scientists use stem cells to create models of human embryos and study our earliest days

Published Tue, 04 Mar 2025 03:59:40 GMT

Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth and why many pregnancies fail.These models are made from stem cells, not egg and sperm, and can’t grow into babies. “They’re complete enough to give you a picture of what may be happening in the embryo during pregnancy, but they’re not so complete that you could actually use them for reproduction,” said Insoo Hyun, an ethicist and director of life sciences at Boston’s Museum of Science. “It just will not work.”Using models also avoids the controversy of using real embryos in research, he said.Several groups are working on the research. Teams with researchers from the United States and England shared their work in two studies published Tuesday in the journal Nature. Other scientists in Israel and China published studies on their work earlier this month that have not yet been reviewed by peers.While previous models mimicked pre-embryos, Hyun said ...

Spain: Heat strokes and dehydration deaths soared in summer of 2022, the hottest year on record

Published Tue, 04 Mar 2025 03:59:40 GMT

MADRID (AP) — Deaths in Spain from heat stroke and dehydration in the hottest months of 2022 — the hottest year on record — jumped by 88% compared to the same period in 2021, the National Statistics Institute said Tuesday.The Institute said 122 people died of heat stroke and 233 of dehydration between May and August last year when temperatures soared in a succession of heat waves. A total of 189 people died from the two conditions in 2021. The data came as Spain sizzled in its first official heat wave of the year, with the state weather agency, AEMET, predicting temperatures to hit 44 degrees Celsius (111 degrees Fahrenheit) in much of the country during a hot spell expected to last until Thursday. Officials in southern Spain said Monday that a 47-year-old agricultural worker had died from heat stroke, the first on record in Spain this year.The weather agency noted that heat waves have become more common during the month of June over the last 12 years.On Monday, the government annou...

¿Por qué las orcas no dejan de embestir barcos en España?

Published Tue, 04 Mar 2025 03:59:40 GMT

(CNN) — Cuando Daniel Kriz vio un par de orcas debajo de su barco mientras cruzaba el estrecho de Gibraltar en abril, pensó: “Otra vez no”.Para Kriz, un veterano capitán que estaba llevando un catamarán de regatas a través del Atlántico, era el segundo encuentro de este tipo en tres años, después de que una manada de orcas rodeara e inutilizara su barco en 2020.“De repente nos sorprendió lo que parecía una mala ola desde el lado”, dijo sobre el incidente reciente. “Eso ocurrió dos veces, y la segunda vez nos dimos cuenta de que teníamos dos orcas debajo del barco, arrancando el timón a mordiscos. Eran dos juveniles, y las adultas estaban dando vueltas, y me pareció que estaban vigilando esa acción”.Las cuatro personas a bordo de la embarcación no sufrieron heridas, pero, sin el control total del barco, Kriz tuvo que llegar al puerto deportivo más cercano usando solo sus motores. Las orcas habían destruido ambos timones —las superficies de co...

Movie Review: Harrison Ford gets a swashbuckling sendoff in ‘Indiana Jones and the Dial of Destiny’

Published Tue, 04 Mar 2025 03:59:40 GMT

Goodbyes don’t tend to mean much in the Hollywood franchise system. Death isn’t a reliable end for characters or, lately, even actors. Technology, nostalgia and the often-inflated value of brands and IP have created a nightmarish cycle of resurrection and regurgitation, curdling what we love most.And yet when someone like Harrison Ford says he’s hanging up Indiana Jones’ fedora, for better or worse, you believe him. “Indiana Jones” producer Frank Marshall has also said that they won’t recast the character, which seems more dubious and, though well-intentioned, something he won’t be able to guarantee. All it takes is a new executive demanding a reboot.Not that it would ever really work, though. Any self-respecting movie fan knows the truth: The magic of Indiana Jones belongs wholly to Harrison Ford. Apparently, he doesn’t even necessarily need Steven Spielberg behind the camera, though, to be fair, the foundation was well-laid for a veteran like James Mangold to step in. But th...
