A large meta-analysis of substance use disorders identifies 220 shared genetic loci (40 new) across European, African, and American populations.
Over 700 gene candidates, highly expressed in numerous brain regions. Looks again like addiction is not just dopamine (ahem).... A top 10% polygenic risk score leads to a 2-3x increased risk of SUD. Very useful data to identify drug targets. link below

This chart made by Peter Gleick shows the proposed cuts to science graphically. This is bad for America.

Please ask Congress to save science.

This is the best in vivo AP propagation movie we got so far. Recorded at 1k Hz from the axonal branches of a fly CNS neuron, using voltage indicator pAce.

Today in @Nature, we share our latest paper. We developed an algorithm to predict novel peptides cleaved by proconvertases across all human tissues. Using this method, we identified BRP, a brain-derived anti-obesity peptide.

We are excited to report the discovery of TIGRs, a widely-occurring RNA-guided system found in bacteria and their viruses. TIGRs consist of a peculiar repeat region which is transcribed into RNA and processed into multiple guide RNAs to direct TIGR-associated proteins to their DNA targets. https://t.co/ketXqFVQqw

Lawyers for the government argued yesterday that the cap on NIH indirect costs would not cause “irreparable harm,”- Tell that to the grad students who would have been admitted at these places and the labs they would have joined! H/T @kyledcheney

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

Call to End Freeze on Federal Grants

The White House's pause on federal grants threatens our nation’s scientific progress. This unprecedented freeze will impact students and trainees who rely on grants, funded investigators, and patients waiting for critical discoveries and treatments, in addition to having an economic impact for employees and employers at universities and organizations that are economic drivers in the U.S.

Read SfN's full statement urging this Administration to lift the freeze to protect the health and security of our nation: https://t.co/UlzkzC59Pr
