It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects. www.nature.com/articles/s44...

It’s how a rapidly warming Arctic - at a rate 4X the global average - and record low Arctic sea ice - helps enhance the patterns that lead to mid-latitude cold air outbreaks… 1/

For the FIRST time ever, researchers have developed a targeted combination therapy that has successfully AND completely ELIMINATED KRAS-driven pancreatic tumors in experimental models. Tumors regressed COMPLETELY with NO recurrence OR major side effects. Let’s talk about that!

They colonize and clog the water-transporting xylem vessels, causing rapid-onset wilt disease—they can fatally wilt plants within days. This timelapse by Jonathan Jacobs shows a sped-up time-course.
