Evolving better E. coli for 75,000 generations. Prof at MSU, but opinions my own. (Ok, I also speak for billions -- er, TRILLIONS -- of E. coli.) Website for LTEE: the-ltee.org Banner pic from NYC, shared by Darwin. (The microbiologist, not the other one.)

Alita Burmeister (@aburmeister.bsky.social) is looking to hire a postdoc (or potentially a PhD student) for projects on phage resistance and evolution. The position description is posted to the Eco-Evo Jobs wiki and also available on her lab's website (arburmeister.weebly.com).

A lot of people, including me, were wondering how an IRB could ever approve this study.

The answer is that no IRB did. The person who β€œsigned off” on approval from the only ethics board that reviewed it had resigned three years earlier. His signature was used without his knowledge.

πŸ‘€The federal judges in West Virginia, where ICE has been pulling over and detaining people on the freeway, are literally screaming about ICE's tactics.

Judge Orders Hearings for Immigration Detainees and Condemns β€˜Terror Against Noncitizens’ As tensions mount between the Trump administration and the courts, the judge called β€œshameless” a claim by officials that her earlier order was not binding.

In a fiery ruling that accused the government of failing to follow court orders, a federal judge ordered the Department of Homeland Security to notify thousands of immigrants detained nationwide that they can join a lawsuit against the government and get either a hearing or be immediately released.

FDA chief Marty Makary says 'everything should be over the counter' unless drug is unsafe or addictive Makary said the FDA is looking at prescription drugs like nausea medications and vaginal estrogen, and hopes to make changes this year.

FDA Chief Makary just said that most drugs should be sold over the counter and not require a prescription, unless it’s β€œunsafe, you need laboratory tests to monitor…or if it could be used for some nefarious purpose or it's addictive”.

Bacteria celebrate as antibiotic resistance enters the chat.

At some point it ceases to be vaccine skepticism. It becomes a a cult-like conviction to shun vaccines and science against all evidence or reason. Even if it means maiming your own child or worse watching them die from a preventable illness. This is unbelievably tragic and this is where we are.

Spatial structure: shaping the ecology and evolution of microbial communities Spatial structure naturally emerges in microbial communities, shaping growth, interactions, and evolution, and revealing how microscale processes scale up

Most microbes don't live in shaking flasks; spatial structure shapes how microbes interact and evolve at every scale, as we discuss in our recent review @jeroenmeijer.bsky.social @simonvanvliet.bsky.social @bedutilh.bsky.social @bramvandijk.bsky.social and others

Brain drain is undermining America’s scientific edge Policy decisions grounded in Maga talking points are helping to fuel a PhD exodus from government

Doing science in the US is starting to feel untenable. The CDC has had no stable leader. RFK Jr broke his promises on vaccines & research. Climate change is denied. Moderna will no longer invest in late stage vaccine trials. Europe and China are seizing the moment.

They also refused to cooperate with Minnesota officials to investigate Renee Good’s death.

What don’t they want the public to know?
