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.)

Richard E. Lenski is an American evolutionary biologist who is the John A. Hannah Distinguished Professor of Microbial Ecology at Michigan State University. He is a member of the National Academy of Sciences and a MacArthur Fellow. Lenski is best known for his still ongoing 37-year-old long-term E. coli evolution experiment, which has been instrumental in understanding the core processes of evolution, including mutation rates, clonal interference, antibiotic resistance, the evolution of novel traits, and speciation. He is also well known for his pioneering work in studying evolution digitally using self-replicating organisms called Avida. .. more

Looking for something new to integrate into an #evolution or #microbiology course? Useful for lectures, labs, homework?

Have a look at our STEPS program, which simulates bacterial evolution, including the #LTEE. Easy web-based interface & lab manual w/ exercises to help develop students' intuition.
Excited to share new #program, STEPS, which can simulate #dynamics of the E. coli Long-Term Evolution Experiment (#LTEE) or other microbes in serial transfer regime.

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.

Dan Koh: In the last year, this leader tried to take sovereign land unilaterally, use the justice system to jail enemies, & actively shut down independent media voices

That was Vladimir Putin—the fact that so many ppl thought I was describing Trump right now shows how much our democracy is at risk

Trump officials have blocked Minnesota law enforcement from accessing materials to investigate the death of Alex Pretti.

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

What don’t they want the public to know?

Metry and her husband of 4 years go to DHS to get their I-130 in motion. "Good news" a DHS employee told them, the form to start her naturalization was approved.

DHS employee asks the husband to follow him through a secure door. When it locks behind him, ICE detains his wife to deport her.
EXCLUSIVE: Terez Metry was 13 when her family fled to Tennessee from Egypt in 2011. Then, they left her behind. She only recently discovered she had an order of removal from 2011. But she was following the legal path to citizenship. On Monday, at a routine DHS meeting, Metry was detained.

This is what the most distant confirmed galaxy looks like. The light we're receiving was emitted when the Universe was ~15x smaller in linear size than today, and right now it's ~30 billion light-years away from us. The light was emitted when the Universe was <300 million years old. Pretty amazing!
News from the edge of the visible universe:

JWST has confirmed this galaxy, MoM-z14, as the most distant one yet studied. We're seeing it as it was 13.5 billion years ago, 98% of the way back to the beginning of time.

(MoM stands for "miracle or mirage.") 🧪🔭

She offered me $2600 to self-deport.
I refused.

They didn't tell me the judge had already ordered my release and return to Minnesota.’

Good News! 28 states have publicly rejected Kennedy’s vaccine schedule.

They choose to follow evidence-based guidance from experts like the American Academy of Pediatrics or the American Academy of Family Physicians.

This is how Sen. Ron Wyden clues the public into activity that he finds extremely alarming. He does a press release about a letter he sent to the director of the CIA that basically says, 'I want to make sure you saw the classified letter I sent early today.' www.wyden.senate.gov/imo/media/do...
Trump's big, ugly budget megabill gives ICE more agents than the FBI, more jails than the federal Bureau of Prisons, and a larger budget than most countries' militaries.

Not one more penny for ICE.
Elon Musk's net worth just hit $800 billion. How?

One of his corporations acquired another one of his corporations.

Meanwhile, Elon's companies pay next to nothing in federal income taxes and get billions of dollars in government contracts.

This is what I mean when I say the system is rigged.
