The U.S. government announced Friday that four huge dams on the Snake River in Washington state will not be removed to help endangered salmon migrate to the ocean.
Two U.S. astronauts about to make the first splashdown return in 45 years said Friday they'll have seasick bags ready to use if needed.
The recent rise of authoritarian nationalist movements has reinforced the tendency of many on the left, and some on the right, to reject all forms of nationalism, writes Rogers M. Smith in "Toward Progressive Narratives of American Identity," published in Polity's May Symposium on the Challenges Facing Democrats.
According to recent Gallup polls, socialism is now more popular than capitalism among Democrats and young people, and support for "some form of socialism" among all Americans is at 43% (compared to 25% in 1942). Policies that went unmentioned or were declared out-of-bounds in elections four years ago—a federal jobs guarantee, single-payer health care, free college, massive tax hikes on the rich,...

Even as Microsoft is reportedly in talks to buy TikTok, U.S. President Donald Trump on Friday said he was looking at lot of alternatives regarding the video app owned by Chinese firm ByteDance, including the possibility of a...
The past few weeks in Victoria highlight how quickly things can turn. We have a long way to go Even though it’s been only six months since we first heard about a novel coronavirus circulating in China, so much has happened that it’s all a bit of a blur. What we do know is that we have a long way to go and there are many challenges that lie ahead of us. Although many countries have managed to...
A new statistical model may help scientists understand how animals make inferences about whether their surroundings are novel or haven't changed enough to be regarded a new context.
Scientists have discovered one of the largest anomalous Hall effects (15,506 siemens per centimeter at 2 Kelvin) ever observed in the new compound, KV3Sb5. This material has a never-before-seen combination of properties: Dirac physics, frustrated magnetism, 2D exfoliatability, and chemical stability. Aside from future fundamental research studying the interplay of these ingredients, the unique...
A breakthrough in fertility science has shattered the universally accepted view of how sperm 'swim'.
A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties. University of Texas at Dallas physicists are studying how the ability of twisted bilayer graphene to conduct electrical current changes in response to mid-infrared light.
A majority of the world population lives on low lying lands near the sea, some of which are predicted to submerge by the end of the 21st century due to rising sea levels.
The number of South African rhinos killed by poachers fell by half in the first six months of the year, but 166 were slaughtered nonetheless, the environment minister said Friday.
A breakthrough in fertility science by researchers from Bristol and Mexico has shattered the universally accepted view of how sperm 'swim'.
Texas researchers from the University of Houston, Baylor University and Texas A&M University have discovered evidence for why the earth cooled dramatically 13,000 years ago, dropping temperatures by about 3 degrees Centigrade.
The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in space, can have special patterns which result in exotic physical properties. Particularly exciting are materials which host multiple types of exotic properties because they give...
Scientists have developed a new model that successfully predicted seven of the Sun's biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.
When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example. High-res imaging shows the cerebellum is 80% of the area of the cortex, indicating it has grown as human behavior and cognition evolved.
When college students learn specific techniques for managing stress and anxiety, their well-being improves across a range of measures and leads to better mental health, a new study finds.
As parts of Spain set record temperatures during a heatwave, people in Britain sweltered and flocked to beaches Friday on the country's hottest day so far this year.
When NASA's Aqua satellite passed over the North Atlantic Ocean, it gathered water vapor data on Isaias, while NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image that showed a more organized tropical cyclone.
Jupiter, named for the king of the ancient Roman gods, commands its own mini-version of our solar system of circling satellites; their movements convinced Galileo Galilei that Earth is not the center of the universe in the early 17th century. More than 400 years later, astronomers will use NASA's James Webb Space Telescope to observe these famous subjects, pushing the observatory's instruments to...
A Purdue University startup is turning gameplay into serious learning for elementary students away from classrooms during the COVID-19 pandemic.
Scientists suggest move may stabilise infections, but stricter rules needed to reduce ratesCoronavirus – latest updatesSee all our coronavirus coverageApplying a handbrake to lockdown easing in England is welcome, but may not be enough to stop a rise in infections, experts have said.Sage, the government’s scientific advisory group, said on Friday that it did not have confidence that the...
