这位被称为“战争部副部长”的高官直接站出来点名批评Anthropic CEO Dario Amodei,说他在“撒谎”,还指责他有“上帝情结”,意思是,他觉得自己能凌驾于体制之上。
They also needed an alternative to conventional X-rays. In a clinical linac, X-ray photons are produced by dumping high-energy electrons into a bremsstrahlung target, which is made of a material with a high atomic number, like tungsten or copper. The target slows the electrons, converting their kinetic energy into X-ray photons. It’s an inherently inefficient process that wastes most of the beam power as heat and makes it extremely difficult to reach the ultrahigh dose rates required for FLASH. High-energy electrons, by contrast, can be switched on and off within milliseconds. And because they have a charge and can be steered by magnets, electrons can be precisely guided to reach tumors deep within the body. (Researchers are also investigating protons and carbon ions; see the sidebar, “What’s the Best Particle for FLASH Therapy?”)

Of course, altering a moonlet’s local orbit doesn’t seem like enough to safeguard Earth from civilization-ending impacts. But now, as long-term observational data has come in, it seems we accomplished more than that. DART actually changed the trajectory of the entire Didymos binary system, altering its orbit around the Sun.。关于这个话题,PDF资料提供了深入分析

While heavy winter rain is normal for the region, Prof Dave Hodgson - an ecologist at the University of Exeter's Cornwall campus - said the volume and persistence this season felt "a bit apocalyptic".
