“I trust you will not allow yourself to be in any way disgusted or annoyed by the considerable abuse and misrepresentation which, unless I am greatly mistaken, is in store for you,” Huxley had written Darwin just before the publication of “The Origin.” “I am sharpening up my claws and beak in readiness.”

"Takei is about to star in the British production of the musical Allegiance, inspired by his childhood as one of more than 120,000 Japanese Americans forced into internment camps after Japan attacked Pearl Harbor in 1941. Now a youthful 85, he says it remains the defining experience of his life – one that shaped him as an actor and an activist."

'From exile, in 1934, (Joseph) Roth wrote, in a furious statement as applicable now as it was then: “The epoch-making discovery of modern dictatorships is the invention of the loud lie, based on the psychologically correct assumption that people will believe a shout when they doubt speech.”

New #preprint from Ardem Patapoutian's lab:

'Here, we show that humans lacking PIEZO2 exhibit impaired bowel sensation and motility. Piezo2 in mouse dorsal root but not nodose ganglia is required to sense gut content, and this activity slows down food transit rates in the stomach, small intestine, and colon. Indeed, Piezo2 is directly required to detect colon distension in vivo. Our study unveils the mechanosensory mechanisms that regulate the transit of luminal contents throughout the gut, which is a critical process to ensure proper digestion, nutrient absorption, and waste removal.'

"In the year since Mr. Malichudis first read about his own work in another news outlet, the scandal has snowballed. A financial journalist learned he had also been wiretapped. The government of Prime Minister Kyriakos Mitsotakis admitted that the state intelligence service was monitoring an opposition leader. Two government officials, including the prime minister’s nephew, have resigned.

It’s been called the Greek Watergate."

"We conclude that, although several ways that induce extended lifespan through mitochondrial dysfunction require a functional mitochondrial unfolded protein response, there is no clear indication that activation of the mitochondrial unfolded protein response is sufficient to extend lifespan, despite the fact that the mitochondrial unfolded protein response impacts almost every aspect of mitochondrial function."

On Piezo as an RNA sensor in the gut:

"This is an important study that resolves a controversy about a proposed molecular linkage between the fields of mechanobiology and RNA signaling. While prior research had claimed that a specific mechanosensitive ion channel in the gut responds to a specific fecal RNA, this study provides compelling evidence that the mechanosensitive ion channel does not respond to the RNA."
