FAQ: How is molecular optogenetics different from photosynthesis? Optogenetics uses light to control cell behavior, while photosynthesis uses it as an energy source. Hence, optogenetic experiments require far less light – often up to 1,000x less than photosynthesis.

A few years ago I was in a position to do something unique in neuroscience. I had been working with the phenomenal Emily G. Jacobs 🦋 @emilyjacobs.bsky.social on menopause and inspired by Laura Pritschet's menstrual study, and I was planning a pregnancy. What if we scanned my brain?? nature.com/articles/s4159…

This is one of my favorite stories I’ve reported, thanks to work from Laura Pritschet Liz Chrastil and Emily G. Jacobs 🦋 @emilyjacobs.bsky.social et al we now have a fairly detailed look at the brain of one woman before, during and after pregnancy. Read for more details over at The Transmitter

.@UCSBPsych's Professor Emily Jacobs and her team shed light on the impacts of pregnancy on the human brain, documenting the first-ever map of a human brain over the course of a pregnancy and postpartum. 🧠 ow.ly/B1R750Tosff

This is just the beginning! Excited to continue bringing this new to the world technology -- using light to control cell behaviour -- to the market! 💡

So grateful to have been part of the inaugural cohort with reprogrants ❤️ Check out the new cohort below ⬇️ For the bold and unconventional thinkers!

Longevity is an answer to so many of the challenges facing America. → Exploding debt + deficits → Slowing GDP → Declining fertility We go into it in detail here (and details matter here, so it's worth the extra characters). nfx.com/post/longevity… Simplified argument

Spent three years looking for a team in Biodefense to invest in. But never found one. So we built it ourselves. Valthos builds next-generation biodefense. As AI and biotech rapidly advance, we're approaching near-universal access to tools with the potential to cure humanity or
