I've written a review on what I think is an extremely exciting direction in cryo-EM:

Metadynamics meets diffusion-based structure prediction: the same trick that drives enhance sampling of MD trajectories can be adapted and applied as steering terms during generation to sample diverse conformations. Seems obvious in hindsight!

A small polymerase ribozyme that can synthesize itself and its complementary strand The emergence of a chemical system capable of self-replication and evolution is a critical event in the origin of life. RNA polymerase ribozymes can replicate RNA, but their large size and structural ...

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?

Excited to share our latest work in @science.org on a new small polymerase.

CIVIL CASE NO. SA-26-CV-415-FB Β§ OPINION AND ORDER OF THE COURT

Civics lesson to the government: Administrative warrants issued by the executive branch to itself do not pass probable cause muster. That is called the fox guarding the henhouse. The
Constitution requires an independent judicial officer.
Accordingly, the Court finds that the Constitution of these United States trumps this
administration's detention of petitioner Adrian Conejo Arias and his minor son, L.C.R. The Great Writ
and release from detention are GRANTED pursuant to the attached Judgment.
Observing human behavior confirms that for some among us, the perfidious lust for unbridled
power and the imposition of cruelty in its quest know no bounds and are bereft of human decency. And
the rule of law be damned.

Ultimately, Petitioners may, because of the arcane United States immigration system, return to
their home country, involuntarily or by self-deportation. But that result should occur through a more
orderly and humane policy than currently in place.
Philadelphia, September 17, 1787: "Well, Dr. Franklin, what do we have?" "A republic, if you
can keep it."
With a judicial finger in the constitutional dike,
It is so ORDERED.

BREAKING: Federal judge orders Adrian Conejo Arias and his minor son, L.C.R., released.

"The Great Writ and release from detention are GRANTED."

"Civics lesson to the government: Administrative warrants issued by the executive branch to itself do not pass probable cause muster."

Judge Biery signed the order with a photo of Liam and two bible verses: The first is "But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven." The second is simply "Jesus wept."

Astonishing thing for a judge to do.
