There are 28,500 U.S. troops deployed to South Korea as part of the U.S. long-term commitment to help defend Seoul from any attack from North Korea.But the U.S. is also trying to array its forces and ships optimally across the Indo-Pacific as a credible deterrent against China for any potential attack on Taiwan and other acts of aggression against allies in the region.No decision has been made on the number of troops deployed to South Korea, but any future footprint would be optimized not only to defend against Pyongyang but also to deter China, one of the officials said. The two officials spoke on condition of anonymity to discuss deliberations that have not been made public.

Hegseth is in Singapore to attend his first Shangri-La dialogue as President Donald Trump’s defense secretary. His South Korean counterpart is not expected to attend due to elections in Seoul.A possible reduction in forces was first reported by The Wall Street Journal.

NUEVA YORK (AP) — Un grupo de científicos ha identificado la evidencia más antigua conocida de herramientas hechas por seres humanos a partir de huesos de ballena.

Los huesos, a los que se dio forma de proyectiles angostos para la caza, fueron descubiertos en excavaciones que datan de hace más de un siglo en el Golfo de Vizcaya, cerca de España y Francia. Los científicos pensaban que las herramientas eran bastante antiguas, pero muchas eran pequeños fragmentos, por lo que era difícil determinar su edad.Still, researchers caution that it’s only been a few months. They’ll need to watch him for years.

“We’re still very much in the early stages of understanding what this medication may have done for KJ,” Ahrens-Nicklas said. “But every day, he’s showing us signs that he’s growing and thriving.”Researchers hope what they learn from KJ will help other rare disease patients.

Gene therapies, which can be extremely expensive to develop, generally target more common disorders in part for simple financial reasons: more patients mean potentially more sales, which can help pay the development costs and generate more profit. The first CRISPR therapy, for example, treats sickle cell disease, a painful blood disorder affecting millions worldwide.
