Really amazing: Using a new technique called "mind-captioning", neuroscientists are able to generate text based on brain representations. This method yields descriptions that capture the thoughts pretty accurately. Lots of clinical applications! https://t.co/HVUE6llwYF

Less than an hour later the first preprint was already paired to q.e.d! 🔥🍷
IT'S HAPPENING! 💥 I'm psyched to launch the collaboration between @qedScience & @openrxiv @biorxivpreprint! Let's go back to concentrating on making discoveries, and not on “getting published”, because it’s not going to matter soon, when feedback & evaluation are detached from

A 42-country analysis of change in cancer patterns with age indicates only colon cancer is clearly on the rise in the young (age 20-49 years). Most of the rest of 12 cancer types were increasing across the age groups. AAPC-average annual percentage change https://t.co/P1gF4FWTJc

Given the recent discussion about aging (and our approach to it) in https://t.co/k0jwH9wPB3, it might be worthwhile to mention that my perspective is: birth defects, failure to regenerate complex organs after damage, cancer, degenerative disease, and aging are all *the same

A Nobel-winning scientist of great modesty and humour, John Gurdon died on 7 October. Not only did he make a discovery that laid the foundations for the field of stem cell research, he also created one of the best environments for research at the Wellcome / CRUK Gurdon Institute.

Saddened to hear of John Gurdon’s passing. A brilliant scientist, generous mentor, and endlessly curious. When he examined my PhD viva in 2006, he’d just come from doing experiments at his bench - at 73. He shaped so many careers, including mine:
