Hitting refresh on biorxiv for a paper to appear... realized my first biorxiv preprint was more than 12 years ago, and on arXiv two years before that! Preprinting sure seemed strange at the time, but it's become my favorite part of the process!

This bright orange life-form could point to new dino discoveries

Colorful lichen living on dinosaur bones reflect infrared light that can be detected by drones, which might lead to finds in remote areas.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

1/ ⚠️ Breaking: At CDC, we've been told the US Government will not officially commemorate World AIDS Day this year. No explanation given.

Photograph of a printed guidance memo stating that the U.S. Government will not be commemorating World AIDS Day this year. Key points include: USG funds should not be used for related events, personnel should refrain from public promotion via social media or other channels, and CDC and other USG staff may attend local events but cannot speak or promote attendance. The memo notes this guidance supersedes previous blanket approval and may require adjustments to planned activities.

This is concerning.

NIH is changing their policy so that staff have to prepare justification for every application that is funded BUT NO DOCUMENTATION FOR APPLICATIONS THAT ARE SKIPPED (BASED ON PERCENTILES).

1/2

An internal document from NIH which states that documentation must be provide for each funded grant but that no documentation need be provided for applications that are not selected for funding including those that are skipped back on overall impact scores.

Microbiologist Dr. Rita Colwell was born #OTD in 1934. She is recognized for her study of global infectious disease spread through water sources. Her research on cholera helped save 𝘤𝘰𝘶𝘯𝘵𝘭𝘦𝘴𝘴 lives.

She was the first female director of the National Science Foundation (NSF), 1998-2004. #WomenInSTEM

Portrait of Dr. Rita Colwell with short silver-gray hair, smiling warmly at the camera. She is wearing round glasses, pearl earrings, a pearl necklace, a white blouse, and a dark blazer. Her arms are confidently crossed, and she stands against a plain medium-gray studio background.

In 1990, 943 million people in China lived on less than $3 a day measured in 2021 dollars – 83% of the population, according to the World Bank. By 2019, the number was brought down to zero. In the US more than 4 million Americans live on less than $3 a day, 3x as many as 35 years ago.

China has brought millions out of poverty. The US has not – by choice

Despite the US’s economic success, income inequality remains breathtaking. But this is no glitch – it’s the system

As I spent more and more of my life under the care of doctors, nurses, and researchers striving to improve the lives of others, I watched as Bobby cut nearly a half billion dollars for research into mRNA vaccines, technology that could be used against certain cancers; slashed billions in funding from the National Institutes of Health, the world's largest sponsor of medical research; and threatened to oust the panel of medical experts charged with recommending preventive cancer screenings. Hundreds of N.I.H. grants and clinical trials were cancelled, affecting thousands of patients. I worried about funding for leukemia and bone-marrow research at Memorial Sloan Kettering. I worried about the trials that were my only shot at remission. Early in my illness, when I
