The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
by injecting the virus into a brain area that you want to study uh the virus will infect all the cells in that region and then make those cells begin to produce this ELO protein so once once the neuron starts to carry this ELO protein it becomes comes light sensitive so you can turn blue light on it and then be able to stimulate it
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
the way that you would put a gene uh into the brain uh is usually by using a virus um so this is uh a virus that that exists in nature but we have engineered it by removing everything that is pathogenic about the virus and then replacing those pathogenic genes with the gene that we're trying to put into the brain so in this case it's the gene from the green algae
we developed a technology called optogenetics and it's a way of studying uh brain cells in in the brain um how they are connected together and how they mediate a memory mediate different types of physiological function the way it works is that we took a gene uh from a green algae and this is a gene that senses light and converts it into U electrical current in the cell so we can put this Gene from the green algae right into the brain cells in the mouse and we can shine blue light or yellow light uh and control the brain activity in this mice
