Lithium deficiency and the onset of Alzheimer’s disease - Nature
Lithium has an essential role in the brain and is deficient early in Alzheimer’s disease, which can be recapitulated in mice and treated with a novel lithium salt that restores the physiological level.

I’m petrified about today’s science news. Genetically modifying crabs to have cheetah genes? This could go sideways fast.

It's 25 yrs to the day since the Human Genome Project & Craig Venter declared joint victory in sequencing the human genome - an ideal time for @wellcometrust.bsky.social to annouce their new project, involving our lab, to begin work towards synthesising human genomes. wellcome.org/news/researc...
