If Democrats Can Lose in Virginia, They Can Lose Almost Anywhere
LOUDOUN COUNTY, Va.—The beer was flowing, the handmade potato chips were self-serve, and hope was in the air. Early in the night, the Loudoun County Democrats who gathered at the Döner Bistro in Leesburg were cautiously—anxiously—optimistic: Sure, it had been a rough year. A global pandemic, regular protests at the local school-board meetings, and the contentious governor's race, rife with misinf

ALMA scientists detect signs of water in a galaxy far, far away
Water has been detected in the most massive galaxy in the early universe, according to new observations from the Atacama Large Millimeter/submillimeter Array (ALMA).

The vast little library inside your cells
The human genome can be thought of as a massive library, containing over 20,000 different "instruction manuals": your genes.

There are even genes that contain information about regulating the genome itself—like books that explain how to organize a library. The ability to regula

Young men are disadvantaged when applying to female dominated jobs
It's not always women who lose out when looking for a job. Men experience disadvantages in hiring processes for female dominated occupations in Germany, the Netherlands, Spain and the United Kingdom. The reverse is not the case for women who apply for typical 'male' jobs. No gender discrimination was found in Norway or the United States. These are the findings of a study by the WZB Berlin Social S

Tropospheric temperature affects tropical cyclone peak intensities in distinct ways
As natural weather disasters, tropical cyclones possess enormous destructiveness related to their intensity (maximum speed of tangential winds in the lower troposphere within 50 km of the tropical cyclone center). The long-term variability of tropical cyclone intensity is related to climate change, and it has been found that there has been a considerable increase in the number and proportion of in

Astronomers make most distant detection yet of fluorine in star-forming galaxy
A new discovery is shedding light on how fluorine — an element found in our bones and teeth as fluoride — is forged in the Universe. Astronomers have detected this element in a galaxy that is so far away its light has taken over 12 billion years to reach us. This is the first time fluorine has been spotted in such a distant star-forming galaxy.

The Atlantic Daily: Good News for Trumpism, Bad News for Trump
Democrats are in trouble. If this year's governor's races are really the bellwethers they're made out to be , the flock's headed right: Virginia went red last night, and typically blue-leaning New Jersey was too close to call. (Incumbent Democrat Phil Murphy managed a narrow win late today .) Just how bad of a sign is that for the governing party going into the 2022 midterms? Pretty bad, our writ

Historien visar att vi kan bryta fossilberoendet
Om vi ska klara Parisavtalets mål på max 1,5 graders global uppvärmning måste vi kraftigt minska användningen av fossilt bränsle, och det snabbt. Men det finns faktorer som gjort det möjligt förr. Att begränsa den globala uppvärmningen till Parisavtalets mål på 1,5 grader kommer sannolikt att kräva att kol- och gasanvändningen minskar i en takt som sällan noterats i något större land. Det visar e

Laboratory will illuminate formation, composition, activity of comets
Researchers have developed a laboratory to simulate comets in space-like conditions. The goal of the Comet Physics Laboratory is to understand the internal structure of comets, as well as how their constituent materials form and react. Many of the lab's future experiments will involve creating sample comet materials with differing compositions. By testing those materials in the space-like chamber,

Gene therapy boosts Parkinson's disease drug benefits
A new gene therapy targeting the small brain region where dopamine neurons reside, the substantia nigra, substantially boosts the benefits of the drug levodopa in Parkinson's. The therapy restored the ability of these neurons to convert levodopa to dopamine. Scientists also showed how damage to the powerplants inside dopamine-releasing neurons triggers Parkinson's. The findings may help identify h

A tailored history of who wears what — and why | Richard Thompson Ford
From puffy trousers to pantsuits and everything in between, law professor and author Richard Thompson Ford takes us on a fascinating tour through the history of fashion and the evolution of dress codes that still influence style today, tracing the real consequences people face for the way they dress. He offers an insightful and eye-opening explanation about why people care so much about what other

Brain's immune system may not be to blame for FASD
Researchers continue to find evidence that the brain' immune system may not be the culprit behind fetal alcohol spectrum disorders. It has long been thought that cells in the brain's immune system called microglia are responsible for the neurological damage that occurs when this type of exposure happens. "We looked for more subtle changes in microglia function this time," says Ania Majewska, prof

Single molecule controls unusual ants' switch from worker to queen-like status
Depending on the outcome of social conflicts, ants of the species Harpegnathos saltator do something unusual: they can switch from a worker to a queen-like status known as gamergate. Now, researchers reporting in the journal Cell on November 4th have made the surprising discovery that a single protein, called Kr-h1 (Krüppel homolog 1), responds to socially regulated hormones to orchestrate this c

Fifty years of the brain's sense of space
Nature, Published online: 04 November 2021; doi:10.1038/d41586-021-03010-7 Neurons in a brain region called the hippocampus were found to be selectively active when rats are in a specific spatial location during natural navigation. The discovery launched research efforts into how the brain supports spatial memory.

Dopamin nyckel vid behandling av social ångest
Nivåerna av dopamin och en positiv förväntan på behandlingen, kan avgöra om patienter med social ångest förbättras eller inte vid medicinering med SSRI. Trots att medicinen påverkar nivåerna av serotonin i hjärnan, var det effekterna på dopamin som hade störst betydelse för förbättring visar en studie från Uppsala universitet. Båda grupperna fick samma medicinska behandling. Men för patienter som

Mutant microbe produces carbon-neutral biofuel
Scientists have modified a microbe so it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity, and light. The microbe, called Rhodopseudomonas palustris TIE-1 (TIE-1), produced a biofuel, n-butanol, that is an authentically carbon-neutral fuel alternative that can be used in blends with diesel or gasoline.

Novel tag provides first detailed look into goliath grouper behavior
Persistent observations of large underwater animals are difficult to achieve without the help of electronic, multi-sensor tags. Data obtained from these sensors provide important insight into the biomechanics, activity patterns, energy expenditure, diving and mating behaviors of these animals, which are otherwise "foreign" to the scientists who study them. In particular, there has been little work
