Revenge of the Poorly Educated: On Will Bunch’s “After the Ivory Tower Falls”

Los Angeles Review of Books 

TALK-SHOW HOST Rush Limbaugh, recipient of the Presidential Medal of Freedom under former president Donald Trump, relied on his listeners’ resentment of college-educated folks throughout the 1990s to stoke the fires of culture war. There was something about what colleges did that convinced many of Limbaugh’s listeners that, in journalist Will Bunch’s words, “nothing in […]

New nanoparticles can perform gene-editing in the lungs

Phys.org 

Engineers at MIT and the University of Massachusetts Medical School have designed a new type of nanoparticle that can be administered to the lungs, where it can deliver messenger RNA encoding useful proteins.



Mice play virtual reality games to reveal how memories are selected for long-term storage

Phys.org 

Neuroscientists watched the brains of mice as they played virtual reality games to elucidate how memory goes from its initial formation in the hippocampus to longer-term storage in the cortex. Reporting in the journal Cell on March 30, they found that the anterior thalamus—a brain region not classically involved in models of memory consolidation—is one essential stopover site where memories are processed and stabilized. By stimulating the anterior thalamus of mice while they were learning a virtual reality maze... Читать дальше...

An improved, visible light-harvesting catalyst to speed up reactions

Phys.org 

Photocatalysis is the use of light to accelerate the rate of a reaction in the presence of a photocatalyst. The catalyst plays a crucial role in this process—it absorbs the light being shined onto it and makes it available in ways that can help accelerate the chemical reaction and also enhance it. These catalysts are used for a variety of light-dependent reactions ranging from the production of paper to the conversion of carbon dioxide to fuel.

Majority of employers not excited about a four-day workweek, according to entrepreneur poll

Helsinki Times 

A recent entrepreneur poll shows that 75% of employer companies would not be willing to try a four-day workweek if employee wages remained the same. "Four out of five employers do not believe that a four-day workweek would improve productivity enough to pay the same salary as before," says Janne Makkula, Director of the Finnish Entrepreneurs. A four-day workweek can be tested locally right now without a government-led operation.

Structure of 'oil-eating' enzyme opens door to bioengineered catalysts

Phys.org 

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first and most challenging step in turning simple hydrocarbons into more useful chemicals. As described in a paper just published in Nature Structural & Molecular Biology, the detailed atomic level "blueprint" suggests ways to engineer the enzyme to produce desired products.

Shining a light on the mechanics of embryo development

Phys.org 

In 1922, French physicist Léon Brillouin predicted an interesting phenomenon—when light is shone on a material, it interacts with the naturally occurring thermal vibrations within it, exchanging some energy in the process. This, in turn, influences how the light is scattered. By measuring the spectrum (color) of the scattered light, we can deduce certain physical characteristics of that material.

Stressed plants emit airborne sounds that can be detected from more than a meter away

Phys.org 

What does a stressed plant sound like? A bit like bubble-wrap being popped. Researchers in Israel report in the journal Cell on March 30 that tomato and tobacco plants that are stressed—from dehydration or having their stems severed—emit sounds that are comparable in volume to normal human conversation. The frequency of these noises is too high for our ears to detect, but they can probably be heard by insects, other mammals, and possibly other plants.

First real-time glimpse of nanoparticles self-assembling into crystals

Phys.org 

For the first time ever, researchers have watched the mesmerizing process of nanoparticles self-assembling into solid materials. In the stunning new videos, particles rain down, tumble along stairsteps and slide around before finally snapping into place to form a crystal's signature stacked layers.

Interview with Anna Cramling for CNN about her experiences as a chess player

Chessdom 

“Being a woman in chess can feel ‘lonely’ says streamer Anna Cramling, as the game grapples with harsh truths,” says Anna Cramling in her interview for CNN. Currently playing the Reykjavik Open 2023 (follow live here / see her result in round 1), Anna is back on the board. She started playing again less than […]
