Adaptive introgression in subdivided populations leaves distinct genomic footprints under global and local selection: a case study in Ciona intestinalis
Adaptive introgression, the transfer of beneficial alleles between species through hybridization, is increasingly recognized as an important source of adaptation to novel environments. However, the th...

One of the things that is going to change is that we’re never ever again going to be able to be dominated by public officials who tell us, ‘Trust the experts,’” Mr. Kennedy said during the Tuesday session.

“If somebody tells you, ‘Masks work, trust the experts,’ A.I. may tell you otherwise,” he added. “If somebody tells you, ‘Social distancing works, trust the experts,’ A.I. may correct that. And if somebody tells you that a vaccine will prevent transmission and infection, or you need to take it to protect your grandmother, A.I. may say it actually doesn’t do that.”

Claude appears to be engaging in academic dishonesty, which could be fireable for a human researcher. But one of AI’s major functions is ethics displacement, a shield that allows cheaters and other bad players to escape accountability.

If you're submitting a reference letter for a PRFB, I was surprised to not see any option for deleting and reuploading, which contradicts the info provided in the email requesting it. In fact, as soon as you select the file it is uploaded and you can't change it. Was fine for me, but beware.

While both nori & wakame are edible seaweed, they are separated by >1 billion (!) years of evolution. Nori is red algae, which acquired its chloroplasts via primary endosymbiosis; wakame is brown algae, which acquired its chloroplasts from another algae. They are about divergent as human vs yeast.
