White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. πŸ§΅πŸ‘‡

Congress has appropriated the funds to NSF but OMB is delaying the release. When funds are released, NSF, which has lost almost 1/5 of its staff, will struggle to evaluate proposals. Since they have to award the funds, big projects with established PIs will benefit. This is how US science dies.

An intrinsically disordered region mediates RNA-binding selectivity and cellular activities of LARP6 - Nature Communications LARP6 is an EMT-associated RNA-binding protein with diverse RNA targets.

πŸŽ‰Proud to present our latest paper, out now in Nature Communications: www.nature.com/articles/s41...

RNA Binding Proteins (RBPs) are often full of intrinsically disordered regions (IDRs), but what these regions do during RNA recognition is often unclear. 1/10

The successes of protein structure prediction are widely known. However, its limitations and failures are less known, especially among non-experts.

Most telling are the failures to predict structure types absent from the training data.

A bird's-eye view of a former Auschwitz II-Birkenau camp showing a wide dirt pathway flanked by parallel rows of barbed-wire fences. Groups of visitors walk along the path, surrounded by the remnants of brick structures and barracks, now reduced to foundations. Green grass contrasts with the somber history of the site, as the path leads toward a guard tower in the distance.

Auschwitz was at the end of a process. We must remember that it did not start from gas chambers.

This hatred gradually developed: from ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.

Messenger RNAs with shorter UTRs tend to live longer on average.

This may reflect that shorter UTRs statistically contain fewer destabilizing regulatory elements.

The relationship depends strongly on cellular context, sequence content, and RNA-binding protein availability.
