MedGemma 1.5 is a major upgrade to our open models for healthcare developers. The new 4B model enables developers to build applications that natively interpret full 3D scans (CTs, MRIs) with high efficiency - a first, we believe, for an open medical generalist model. MedGemma

Venezuela used to be twice as wealthy as Chile. Then Chile adopted free-market principles while Venezuela chose socialism. Now Chile is the wealthiest large country in South America and Venezuela the poorest. Free markets work, socialism makes nations poor.

Neuralink will start high-volume production of brain-computer interface devices and move to a streamlined, almost entirely automated surgical procedure in 2026. Device threads will go through the dura, without the need to remove it. This is a big deal.

On Wednesday evening, a monumental pediatric cancer bill made it to the Senate floor—the last hurdle before passage. Cancer victims watched in the gallery. Sibling survivors too. And then... it failed. Because of one vote. Bernie Sanders'. Here's why. https://t.co/j6zfxvJxTm
