Canada has announced a government-backed program to hire 64 researchers, with 48 coming from the United States, including Harvard and MIT, to join Canadian universities. The initiative, funded with over C$500 million, aims to bolster fields from climate science to artificial intelligence as tensions with the US influence academic mobility. The shift follows policy crackdowns in the United States and a broader tradewar backdrop.
This week has seen several medical research and regulatory developments. Insilico Medicine has reported that its experimental drug rentosertib changed blood‑protein patterns that aging clocks read as three to four years younger in a small trial. Stanford teams have published studies showing they can grow hindbrain neurons separately and implant human cortical organoids into mice.
