I once cornered a wayward turkey in my backyard and it took off to fly over the fence. It was quite a production, much like a helicopter

This is outrageous, and (though it was completely obvious he should never have held this spot), Vinay Prasad needs to go. This vaccine candidate deserves review, not ideologically motivated rejection. Lives are at stake. www.statnews.com/2026/02/11/m...

Prasad overruled FDA staff to reject Moderna's flu vaccine application

The rejection is the latest instance of Vinay Prasad overruling career FDA scientists to place vaccines under harsher scrutiny.

It is absolutely outrageous that Moderna’s flu vaccine was met with a “refusal-to-file” even after their approved their protocol with FDA and carried out the trial as agreed. This vaccine works better in older adults than the current flu vaccines.

Moderna says FDA refuses its application for new mRNA flu vaccine

I am a huge fan of Lindsey Vonn and have no problem with her racing after the ACL issue. I do think it would be funny if she trolled everyone and said she was hoping to still compete in some events with a fractured leg.

Not to make light of a tragic situation, but I have started to refer to the HHS staff who are so obsessed with the pandemic as the “Branch Covidians”…

🚨BREAKING: Puerto Rico has been part of the United States since 1898, and people still act confused that Puerto Ricans are American.

States that joined after Puerto Rico:
• Oklahoma — 1907
• New Mexico — 1912
• Arizona — 1912
• Alaska — 1959
• Hawaii — 1959

Yet somehow this is still news to folks.

We already did it for chimpanzees. And it was long overdue. We should have immediately moved the conversation to retiring other primates, but there’s been major hindrances to those efforts.

I don’t have the energy to read the details about plans to convert the Oregon Primate Center to a sanctuary, but I will say this: we are far overdue for retiring primates used in biomedical research to sanctuaries or other similar retirement care.

We were in no rush and had blocked out the whole day for it, but I think it could easily be done in 3 hours with some pre-planning and streamlined setup. It's nice to be able to have pre-sequenced data on hand so they can see the end product as soon as they 'ship' their samples/finish the protocol.

I recently took my undergrads through the process of DNA extraction, PCR, and sample prep for metagenomics. (from soil for fungal metagenomics)

It took them 2 hours to extract the DNA, about 30 minutes to start the PCR, and another hour to purify and QC the product (using previous days run).

Our DHS reform demands are exceedingly reasonable.

We're asking ICE to do nothing more than follow the standards that the vast majority of law enforcement agencies already follow.

Republicans, the ball is in your court. The clock is ticking.

Do you know if that discusses a lab that could be done in 2-3 hours?

Jonathan Eisen @phylogenomics.bsky.social · 3d

I am looking for examples of a 2-3 hour lab activity for a course that would allow college students to get some experience connected to environmental DNA studies (e.g., e-DNA, rRNA/ITS PCR, metagenomics, etc). Ideally this would have some DNA extraction and some follow up processing / analysis.
