Don't know if you are willing to upgrade to a smart watch, but I had a Garmin Forerunner for more than a year and half and its heart rate monitor works well. Battery life is still consistently long. It came recommended by an ultrarunner friend of mine.

Trump order gives political appointees vast powers over research grants Researchers are alarmed that the move might upend a long-standing tradition of peer-review for grants.

Trump's new executive order "looks like an explicit attempt to destroy peer review for federal science grants,โ€ a physicist in Texas tells @dangaristo.bsky.social. ๐Ÿงช

I realize broad science-literacy problems cannot generally be solved just by shoving more facts at people but I really wish more people understood that the entire purpose and mechanism of a vaccine is to educate your OWN immune system, making it about the most "natural" medical intervention possible

New executive order puts all grants under political control All new funding on hold until Trump administration can cancel any previously funded grants.

"In short, the new rules would mean that all federal science research would need to be approved by a political appointee who may have no expertise in the relevant areas, and the research can be canceled at any time if the political winds change." arstechnica.com/science/2025...

9. I simply cannot ethically hire anyone on federal funds under these new conditions, and I will not do so going forward.

That hamstrings my research, but worse it prevents the development of brilliant, talented researchers like my former students who are professors, startup founders, and more.

1. Federal funding for research promotes tech, biomedical, and scientific discovery in the US, and provides training for the sci/tech workforce that has brought immeasurable wealth to the US over the past 75 years.

Today's executive order includes a provision that will obliterate both functions.

Look at that hydrograph! This is from a USGS monitoring well in Christiansburg, Montgomery County, VA. Observation well 27F2 SOW 019 is 450' deep, completed in carbonate rocks of the Elbrook Formation and well known for its response to quakes.

Reminds me of one of my favorite quotes from a video game:

"Are all the accomplishments of humanity fated to be nothing more than a layer of broken plastic shards thinly strewn across a fossil bed, sandwiched between the Burgess Shale and an eon's worth of mud?"

Devastating for US Antarctic researchers. US abdicating multiple global leadership roles in marine science. USAP people, we need a professional lobbyist-large sections of both senate and house bills dedicated to drilling and nothing about the NBP. Community led push needed and a comms strategy.

Iโ€™m convening a session at a planetary science conference this fall and people keep withdrawing their presentations. So far every one has been withdrawn because of lack of travel support. Itโ€™s all folks coming from the US. This administration is killing scientific disciplines in big ways and small
