A break from Christmas content to enjoy this capybara eating a banana. From FranΓ§ois Froger's 'A relation of a voyage ...' (London, 1698).

Organelles do NOT have a single uniform pH.
And if you think they must, because β€œprotons diffuse fast,” this paper is for you.
A thread on why that assumption is wrong; and what we found instead. 🧡 1/n

Agriculture’s new album The Spiritual Sound is available everywhere today.

The record is a study in joy and intensity, carrying forward the ecstatic spirit of their debut while pushing deeper into grief, transcendence, and renewal.

Excited to share the latest work by outstanding PhD student @kdc509.bsky.social. This was one of our first forays into experimental evolution and uncovered some cool connections between potassium transport and antimicrobial resistance in S. aureus. Major kudos to Killian!

The diversity subprograms of the primary NIH fellowships were completely terminated, so anyone who submitted one was just rejected instead of being able to transfer to the main one. People people who already had one had it cancelled.

I’m patenting a constant anti-unit of temperature called the Bernard. 1 B = 10^30. Then 30 Β°F is just 1.92 B and 100 Β°F is 2.19 B. The beautiful thing is then 1 = 1 B/B.

One added benefit is that at 1 we have Ξ² = T.

That’s why I personally get rid of the ambiguity and just have 0 = 0 K and 1 = the Planck temperature. It’s much clearer to have 30Β°F = 1.92*10^-30 and 100Β°F = 2.19*10^-30. Avoids any confusion.

The likelihood of getting a usable answer for a tool seems to be proportional to how many people have posted about it on stackoverflow.
