Minnesota: "School officials say the [5-year-old] child was used as bait. They say [ICE] agents made little Liam knock on the door to ask to be let in in order to see if anyone else was home."

Dark skies reflect my sadness at the firings of all the humans that help keep the #GreatLakes as healthy as possible. Tonight I mourn the loss of the 14 @usfws.bsky.social employees that kept the invasive sea lamprey at bay. My fishery will be hurt. 😢😢🌊🌊

“In one example from [OR], beavers built dams on the property of a large, multimillion-dollar stormwater treatment facility. When scientists looked more closely, they learned that the animals were able to filter out heavy metals and other pollutants about twice as well as the human-built structure.”

“Beaver dams can be massive structures. The largest beaver dam on record is in Wood Buffalo National Park in Canada, stretching the length of seven football fields. The dam is so big, it can be seen from space.”

You say: they shutdown USAID. You mean: they illegally broke in to a secure facility over a weekend, hijacked sensitive data on vulnerable people and US businesses, destroyed property Americans paid for, cut off resources for sick and hungry families, and fired Americans across the country.

Yes. My husband is an NIH-funded scientist studying infectious diseases such as whooping cough, covid, & influenza. The current grant funding his salary runs out of money this summer; a delay in grant reviews means he won’t get a new grant funded before then. He’ll lose his job.

Just had a sample of the Eaton Fire ash that is in my driveway run on the department XRF. Is there titanium (new house paint)? Yup. Lead (old house paint)? You betcha. Heavy metals? Check. Treat that ash like it's toxic folks (because it is)
A computer screen with a display showing output from an xray diffraction spectrometer. Close up view showing fraction of metals. Fun stuff.

As 12,000 remain displaced from Helene, campers become homes. The problem is keeping them warm
More Western North Carolina residents are turning to campers as temporary homes as housing demand remains high after Helene.

The NYT could have explored interesting questions (Why do some investors stay committed to this idea even when there’s no clear market? Why are we relying on VC and charity to drive innovation, and what would the alternatives be? What does the broader decrease in $$ for climatetech portend?)

It *is* weird that some species of sharks lay eggs while some give live birth! And it's even weirder than that- there are even more modes of reproduction among sharks, including some *only found in sharks*. How did that happen?I don't know. It's a surprisingly biodiverse group, and an ancient one
