On an August morning in 2008, Tony Wyss-Coray sat in a conference   room at the Veterans Affairs hospital in Palo Alto, California, waiting   for his lab’s weekly meeting to begin. Wyss-Coray, a professor of   neurology at Stanford University, was leading a young group of   researchers who studied ageing and neurodegeneration. As a rule, the   gatherings were forgettable affairs – the incremental nature of   scientific progress does not lend itself to big surprises. But a lab   member scheduled to speak that day had taken on a radical project, and   he had new results to share.
 
  Saul Villeda, an ebullient PhD student with slick black hair and a   goatee, had spent the past year engrossed in research that called to   mind the speculative medical science of the middle ages. He was   investigating whether the old and frail could be rejuvenated by   infusions of blood from the young. The hypothesis was not as absurd as   it might sound.
 
  Villeda had conducted pilot studies with pairs of surgically   conjoined mice that shared a blood supply for several weeks. Young mice   received blood...

President Trump and health secretary Robert F. Kennedy Jr. have characterized the rise in autism diagnoses in recent years as an epidemic requiring emergency intervention.
This approach is factually wrong: The broadening definition of autism and the improvement in diagnosis...

            We Texans like to do things our way — leave some hide on the fence rather than stay corralled, as goes a line in Wallace O. Chariton’s Texas dictionary This Dog’ll Hunt. Lately, I’ve been wondering what this ethos...

[OHSU News/Christine Torres Hicks]
On September 30th, a team of 21 scientists from Oregon Health & Science University (OHSU) published a significant paper in Nature Communications, with a scientifically accurate but, to many, somewhat abstruse headline:
Induction of experimental cell division to generate cells with reduced chromosome ploidy
The lead authors were Shoukhrat Mitalipov, recently described here as “a push-the-envelope biologist,” and his long-term colleague Paula Amato. (Recall that in July the pair had co-published with...
