Save the Whales. But Save the Microbes, Too.

Microbes sustain all ecosystems yet they’re nearly absent from conservation frameworks.
The @IUCN Microbial Conservation Specialist Group aims to change that.
Honored to co-chair this global effort.

Predatory practices plague modern science, but the origins & reasons of their success can be identifiedβ€”and solutions exist. Instead of blacklists, funding agencies should foster accreditation systems. See analyses & proposals of the EAM Task Force of @femsmicro.org on the matter shorturl.at/gVXJR

HiPOD: Colorful Layers in a Crater Wall

A kilometer-wide cutout shows layers sloping from the crater’s rim at right downward toward its floor. A gradient of enhanced colors indicates diverse compositions.

Opinion | Warning: Our Stock Market Is Looking Like a Bubble

And the bubble: "In financial markets, a bubble occurs when the level of investment in an asset becomes persistently detached from the amount of profit that asset could plausibly generate... A.I. investment fits that pattern."

U.S. measles cases continue to climb, with outbreaks across the country In South Carolina, more than 150 unvaccinated schoolkids are under quarantine after being exposed to measles. Across the U.S., total case counts could be even higher than the official number.

β€œCDC has confirmed 44 measles outbreaks in 41 states this year…The vast majority of cases were in people who were unvaccinated; 27% percent have been in children under the age of 5. About 1 in 8 measles cases have resulted in hospitalization.”

Vaccination is so important to protect our communities.

We still can’t predict much of anything in biology Biology is hard. Yes, even for AI.

AI Data Centers Are Sending Power Bills Soaring Wholesale electricity costs as much as 267% more than it did five years ago in areas near data centers. That’s being passed on to customers.

Not sure people realize how INSANELY DRAINING data centers will be on our planet.

If you imagine data centers as their own country, they'll rank fourth in global electricity use by 2035 β€” outranked only by China, India, and the U.S.

The rich must eat less meat ο»ΏScientists say rich countries need to eat a lot less meat. Will the environmental movement finally listen?

β€œFor the past 2 decades, scientists have…landed on the same takeawaysβ€”esp. that rich countries must shift their diets to be more plant-based. But that message has, with few exceptions, failed to incite action by governments and food companies, or even the environmental movement itself.” #EatLancet

Scientific illustration showing a cross-section of Saturn’s moon Enceladus. It features three labelled layers: An ice shell at the top, with visible cracks releasing jets of water vapour into space; an ocean in the middle, depicted as a large body of water beneath the ice; a rocky core at the bottom, shown emitting heat that may drive the jets. In the background, Saturn and its rings are visible in space.

On Earth, these molecules are involved in chemical reaction chains that lead to the more complex molecules essential for life.

It’s good for science and scientists.

Microbial Resuscitation and Growth Rates in Deep Permafrost: Lipid Stable Isotope Probing Results From the Permafrost Research Tunnel in Fox, Alaska Microbial growth is extremely slow within the first 30Β days of thaw. Temperature may drive which taxa are active, but not growth rates Subsurface microbes preferentially produce glycolipids over ...

The vast majority of permafrost exists in the subsurface. What happens when this deep, ancient permafrost thaws? How fast does it take microbial communities to "wake up"?

This project now published in JGR, with @isotopes.bsky.social , @kopflab.bsky.social , et al., aims to address that question!

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.
