NIH Grant Terminations Disrupt 1 in 30 Clinical Trials, Impacting Over 74,000 Participants | AJMC Infectious disease was hit hardest by funding cuts to NIH grant for clinical trials that did not align with the Trump administration's priorities.

JAMA study: NIH grant terminations disrupted 3.5% of active clinical trials, affecting over 74,000 patients and resulting in a $1.81 billion funding loss. More than 115 active cancer trials were disrupted. www.ajmc.com/view/nih-gra...

Scientists Changed the Blood Type of a Kidney. That’s Extraordinary. Transforming organs from any blood type into the universal donor Type O could help patients receive transplants faster.

The world seems like we are going backwards at the moment, so it is important to take the time to spread awareness of advances.

Scientists have developed an enzyme that converts organs into universal 'O' type. This is huge.

Good news is stopgap contributions will keep core FlyBase operations active. But community support remains essential. Please donate @FlyBase and share! 1/2

We find the fly development gene bicoid is much older than previously thought (~20 million yrs older!) πŸͺ°πŸ§¬

To pinpoint its origins we tackled the Diptera phylogeny, providing some resolution (many open questions remain).

No. What they mean is, they're gonna hire the unqualified nephew of a Senator for something, and now they've made a mechanism to give him the federal money instead.
