🇳🇴 Inside the Extreme Plan to Refreeze the Arctic | WSJ Future of Everything
“A method normally used to create ice-skating rinks is now coming to the rescue of melting sea ice in the Arctic. Since satellite records began in 1979, summer Arctic sea ice has shrunk by around 13% per decade. Could making more ice be a potential solution to this issue?”

Evidence for dynastic succession among early Celtic elites in Central Europe
“The historical and archaeological record leave no doubt that the development of culture and population in southwestern Germany was temporarily characterized by profound discontinuities, particularly during the third to first century BCE. The definitive end of the 2,000 years of relative genetic continuity from the Bronze throughout the Iron Age in southern Germany is marked by a sudden, sharp increase of Steppe-related ancestry during the Late Antiquity and Early Middle Ages.”

Mathematicians Attempt to Glimpse Past the Big Bang
“Researchers already knew that in a universe with so-called dark energy, but without matter, the start of inflation identified in the BGV theorem is a coordinate singularity that can be eliminated. But the real universe has matter, of course. Might mathematical tricks also make it possible to get around its singularity? The researchers showed that if the amount of matter is negligible compared to the amount of dark energy, then the singularity can be eliminated.”

Earliest, most distant galaxy discovered with James Webb Space Telescope
“The two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the Big Bang, have been discovered using NASA’s James Webb Space Telescope (JWST), an international team of astronomers today announced.”

Fossil viruses hidden in our DNA thousands of years ago could be the cause of depression, study finds
“Ancient DNA present in humans may be linked to major psychiatric disorders like depression, researchers have said.
DNA sequences originating from ancient infections are found in the brain, with some contributing to susceptibility for conditions like schizophrenia, bipolar disorder, and depression, a study found”

Ancient genomes revealed the complex human interactions of the ancient western Tibetans
“Outside the Tibetan Plateau, the western Tibetan Plateau populations interacted with both South and Central Asian populations at least 2,000 years ago, and the South Asian-related genetic influence, despite being very limited, was from the Indus Valley Civilization (IVC) migrants in Central Asia instead of the IVC populations from the Indus Valley.”
"Hundreds of cancer papers mention cell lines that don’t seem to exist" 👀
“...looks like a massive invention of data and experiments that probably never happened," Some have been cited in reviews, this could "confuse and mislead scientists".

Mesmerising microbes: bacteria as you’ve never seen it before – in pictures
“As a side hustle he manipulates and photographs the microbial world; his images are collected in a book, Beautiful Bacteria. Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative.”
"She criticized my organizational skills and told me that she didn’t see a passion or spark for doing research in me."
Pleading to passion are cop outs for not paying your, or providing sufficient guidance. This was squarely on the PI to begin with, by not reading the room or asking for timely feedback on workload. The the response left a culture of fear (nor one of responsibility and disclosure). Poor management as ever.
“The first known calculation of the Earth’s circumference was made 2300 years ago by a man called Eratosthenes. I remember in school, how impressed I was by how accurately the Earth’s circumference was measured such long time ago. Today we’re going to take a closer look on how his calculation was made.”
“The Harvard team established the practical makings of the first quantum internet by entangling two quantum memory nodes separated by optical fiber link deployed over a roughly 22-mile loop through Cambridge, Somerville, Watertown, and Boston.”
You can tell #Kuhn is thinking of #Wittgenstein, PI here: "to imagine a language means to imagine a form of life." This is from "Scientific Knowledge as Historical Product," 1977, first essay in The Essential Tension and also in The Last Writings of Thomas S. Kuhn.
Have any good investigative journalists done pieces on how the slant of donors, the power of large universities "strategic communications" departments, and the evisceration of newsrooms have affected how the public gets access to reliable scientific research and information in the public interest? #Science#Newstodon#Journalism@academicchatter
