Ohio State announces every student will use AI in class COLUMBUS, Ohio (WCMH) โ€” Starting this fall, every Ohio State student will be asked to use artificial intelligence. โ€œThrough AI Fluency, Ohio State students will be โ€˜bilingualโ€™ โ€” fluent โ€ฆ

"Through AI Fluency, Ohio State students will be โ€˜bilingualโ€™ โ€” fluent in both their major field of study and the application of AI in that area"

Ohio State really not beating the allegations out of Ann Arbor here.

Neutrophils secrete exosome-associated DNA to resolve sterile acute inflammation - Nature Cell Biology Arya et al. report that migrating neutrophils resolve acute inflammation by releasing exosomes associated with nuclear DNA. This process is distinct from the release of neutrophil extracellular traps,...

Excited to share our recently published study on how DNA secretion in neutrophils modulates their inflammatory response spearheaded by @sbarya.bsky.social

Thanks to all our collaborators and contributors for their help getting this story to press.

Fascinating study with absolutely mind-blowing good EM images. Iโ€™m curious about these trimmer and junction points that form in the HFs. How stable are these structures? Is there a unique lipid composition required for this?

Also, is the idea that this is limited to HF structures or canon MVBs too?

Many brilliant scientists are now being punished by having our funding terminated because we are from underrepresented groups. We did everything right and we EARNED these awards. Remember us when youโ€™re making decisions on whether DEI should be sacrificed to โ€œprotectโ€ research funding. #InMyFeelings

Nucleoplasmic signals promote directed transmembrane protein import simultaneously via multiple channels of nuclear pores - Nature Communications The contribution of central and peripheral channels of nuclear pores to transport of transmembrane proteins is unclear. Here the authors show that most inner nuclear membrane proteins use only periphe...

This adds to another fascinating paper showing that membrane proteins like lamin B receptor travel not through the central channel at all, but around the side of the nuclear pore complex through a peripheral channel.

Incredible findings regarding the mechanism of active transport through Nuclear Pore Complexes. Seems importin travels only through the periphery of the central channel leaving a large dead zone in the center.
