If you’re at #ASMS2025 come stop by my poster (ThP304) to learn about how we hacked an RGA to measure trace atmospheric species using low cost RF oscillator circuits!

"People will not lose their Medicaid if they can overcome an impossible obstacle course of administrative burdens we are imposing precisely because we know people can't overcome them" - would be more accurate, but less catchy. 🧵
“People will not lose their Medicaid unless they choose to do so," House Speaker Mike Johnson said.
Several experts and organizations expose this for the lie that it is.

Mike Johnson and Russ Vought Continue to Lie About Medicaid Cuts
House Speaker Mike Johnson and OMB Director Russ Vought denied that people will lose Medicaid coverage under the Republican budget. Experts disagree.

It's been years since I spent a day fiddling in the lab. Testing the frequency dependence of our ion guides using @stevenjkregel.bsky.social slick flange mounted RF oscillators. #WisconsinOscillator #opensource pubs.acs.org/doi/10.1021/...

Yesterday, I confidently had my kids ride the school bus during a tornado watch. Why? Because NOAA scientists create realtime products that allow us to evaluate severe weather. I can't imagine a world where AI generates products I trust more than this.

Shout out to the disabled community for always showing up, always being on the right side of history and justice, always willing to put their bodies on the line, all for the cause of making sure *everyone* has the basic dignity of health care.
BREAKING: The scene at the Rayburn Building is pure rebellion. Protesters are swarming in during live hearings on Medicaid cuts.
Security’s losing control. Because when the government wages war on the poor, the poor fight back.

Got mine today as well. Apparently, studying air quality is "no longer consistent with EPA funding priorities."
Unbelievable and evil. Trump administration just terminated my EPA grant focused on PFAS. They say they support PFAS. All lies. This is so crazy! The memo we received was ridiculous!!!!

This is truly misguided. How about going after dental floss manufacturers that produce floss that is upwards of 25% PFAS that kids rub all over their teeth every day?

I shared a controversial take the other day at an event and I decided to write it down in a longer format: I’m afraid AI won't give us a compressed 21st century.

Most people are not political scientists using formal definitions. So I am curious when is the moment that people tell themselves "oh, I live under an authoritarian government now." Because what else is this?

@cwiedinm.bsky.social has co-authored a fantastic conversation article on the massive effort that underpins weather forecasting ☁️🌀🌧️⛅❄️⚡

NOAA’s vast public weather data powers the local forecasts on your phone and TV – a private company alone couldn’t match it
NOAA operates fleets of satellites, sensors on airplanes and ocean-going buoys, as well as radar, providing the data used by weather forecasters nationwide – and freely available to anyone.
