In their juvenile stage, terrestrial Eastern Newts (Notophthalmus viridescens), also known as red efts, produce tetrodotoxin, the same NaV channel blocking-neurotoxin as pufferfish. The striking coloration is an aposematism.

Emergency medicine physician-scientist superstar Debra Houry resigned her post as Chief Medical Officer of the CDC yesterday, along with other top officials. This is terrible news. American public health is being completely gutted by this administration.

Just took to the House Floor to speak in support of a country where everyone can afford to live the good life.

And in strong opposition to Trump’s One Big Ugly Bill that is devastating to everyday Americans.

We will not be silenced.

Another reason why I love #Vermont:

Our first-of-its kind law that bars schools from using social media platforms to communicate or engage in academic and extracurricular activities with students, along with banning cell phones in schools.

Courage. Now more than ever. These NIH staffers just stood up to Trump, RFK Jr., Bhattacharya. We need to have their backs. The administration will come for each of them, one and all now. apnews.com/article/nih-...

NIH scientists go public to criticize Trump's deep cuts in public health research

Scores of National Institutes of Health researchers and staffers have come forward to send their Trump-appointed leader a letter challenging policies they say undermine the NIH mission.

Cold stored #platelets win the race! They can be given much faster during trauma resuscitation because they can be kept near point of care. Great work from Macky Neal and team @pittsurgery.bsky.social

The DOGE chainsaw just hit a huge spike! An emergency ruling by a federal judge in California has temporarily halted the illegal overhaul of the federal government including attacks #NIH & #NSF.

Resistance works, but our legal system takes time. Hang in there folks.
