Thread: our latest #preprint looks at long-term #proteome #evolution phenomena and asks #macroevolutionary #LevelsOfSelection questions https://biorxiv.org/content/10.1101/2022.10.27.514087v1 1/11 (Repeat for new server).

Excited to share that our study on how cell-cell affinity between two cell lineages locally controls cell shapes and globally drives self-organization of an entire tissue is out now in Nature Communications.

We get a straight line only when the Sun rises at one point on the horizon, is straight overhead at noon, and sets at the opposite point of the horizon. This would happen every day if you lived at the equator and the Earth's axis wasn't tilted. But in reality this situation is rare.

So, the shadow traced out by a sundial's tip is usually a HYPERBOLA.

You can play around with these hyperbola shadows here, using Geogrebra:

Can someone induce forgetting of an unpleasant memory without knowing it? YES!! With Zijian Zhu and Yingying Wang, we report a method that induces forgetting without drugs, brain stimulation or awareness #PTSD #forgetting #memory.

Or is it? We just published this article proposing that fear extinction, at least in mammals, is actually mediated by active forgetting. https://www.nature.com/articles/s41386-021-01131-1

In my course MCB111 "mathematics in biology", we just learned about Hopfield networks and the Hebbian learning. Can anyone give a critical reading of this paper for us?

Hi all #introduction
I’m a graduate student at max planck institute for biological cybernetics Tübingen working at the intersection of behavior, systems and computational neuroscience. Our model organism of interest is zebrafish. For now I am here to connect/ interact with people from #neuroscience and #ml ..

#introduction post! My name is Sonia Roberts (she/her) and I'm a postdoc at Northeastern University developing knitted sensors that could be used to make soft, fully knitted robots. My PhD work was on legged robots running around in the desert -- and if you've ever gone on a beach run, you know why that's hard. I have also done some science and technology policy work. I like to learn about what's going on in other fields so I try to follow a lot of academics in different areas!
