How do transposons jump when they’re released from host control? I babysat two chromosomes for 2 years, making sure they are ok without most piRNAs. Here’s what we found & excited to share my 1st postdoc paper: “piRNA loss unleashes episodic transposition bursts” www.biorxiv.org/content/10.6...

piRNA loss unleashes episodic transposition bursts

In Metazoa, transposon expression is suppressed by the piRNA pathway, and disruption of this pathway leads to rampant transposon expression. However, it remains unclear whether increased transposon ex...

Biomedical scientists - a reminder that NIH proposes to "improve" peer review by hiding impact scores from Program Officers and applicants, and binning applications into broad categories of "Most competitive,""Competitive," or "Not discussed." Please provide feedback before the October 13 deadline!

A massive update: At least ~15 companies~ are selling scientists antibodies using faked validation data. We've documented 18,000+ manipulated images on 17,000+ products sold by leading laboratory suppliers including Thermo Fisher, Abcam, Santa Cruz Biotechnology, Millipore Sigma and Bio-Techne. 1/🧵

[JOB!] I'm hiring for a really exciting postdoc position. A combination of breeding experiments, conservation genomics, and student mentorship.

bioRxiv/medRxiv have been dealing with endless bot attacks recently (plus usual DDOS stuff, etc). Tricky to address without impacting genuine users - many of you affected. Apologies. We're working with our hosting service on solutions & think we're getting there [he shouts in his Red Queen costume].

My lab just opened at Lehigh University - we study the origins, mechanisms, and impacts of the rapid evolution of the chromosome segregation machinery. I'm looking for 2 team members (postdoc and lab tech) who are passionate about evolution and cell division! See the opportunities at dudkalab.me.

The Dudka Lab at Lehigh University studies how rapid evolution of chromosome segregation machinery impacts health, fertility, and disease.

A new study shows that Medicare for All would save over 114,000 lives and over $1 trillion every year. The new research out of Yale shows that reductions in administrative overhead, lower pharmaceutical prices, less fraudulent billing, and fewer emergency care trips would lead to huge savings. /1

"Do not tell me we cannot afford Medicare for All," the senator said. "What we cannot afford is a broken healthcare system based on greed."

Confronted with an obvious need for renewable energy, Trump admin officials used taxpayer money to scuttle an offshore wind project. Then they did it again. And again. And again. And this week, again. Total price tag in wasted taxpayer money: ~$4 billion and counting www.ms.now/rachel-maddo...

Team Trump uses taxpayer money to scuttle yet another renewable energy project

As one key Democratic member of Congress summarized, “It is hard to imagine a more backwards use of taxpayer money.”

Trump & Russ Vought proposed a rule to take every federal grant in America hostage. They don't care about making our tax dollars work better—they just want them to work for Trump. Well, Democrats BLOCKED their corrupt rule, and I'll be fighting to kill it permanently.

America's R1 universities educate ~8–9 million students (undergraduate + graduate) -> more than 1/3 of U.S. college students (vs. the ~0.6% of Ivies). Undermining this system threatens the institutions that train our workforce and drive scientific innovation. www.science.org/doi/10.1126/...

An American research crisis with real human consequences

Ivy League universities have dominated recent news headlines, having become popular targets for critics of higher education. But the threats they face—cuts to federal research funding, assaults on aca...
