Phys.org / FIFA and pop superstars should discount tickets for fans to keep climate costs of 'mega-events' down, say researchers
The vast majority of carbon emissions caused by "mega-events" such as World Cups and global concert tours come from audience travel, according to University of Cambridge researchers. In a new study, researchers estimate that ...
Phys.org / A new stellar census strengthens the case for a 13.8-billion-year-old universe
Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported ...
Phys.org / New process turns mixed plastic waste directly into hydrogen fuel without sorting
Plastic has become a ubiquitous part of modern life—in water bottles, shopping bags and car dashboards. But once discarded, it is among the hardest materials on Earth to recycle. Most recycling processes require plastics ...
Phys.org / Physicists create first room-temperature quantum material
Quantum materials could transform technologies ranging from powerful computers and ultrasecure communications to advanced energy systems. But there has always been one major obstacle.
Phys.org / T. rex babies were born ready to run and feed themselves
Tyrannosaurus rex was a giant of the prehistoric world, standing up to 13 feet (4 meters) tall and weighing around 9 tons (8 tonnes). So you might expect that its hatchlings were also a considerable size.
Phys.org / Alien world chemistry found inside meteorite that struck New Jersey home
On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time ...
Phys.org / Scientists recover sub-Saharan Africa's oldest ancient animal DNA
Ancient DNA can be a powerful tool for helping us reconstruct the long-dead past. Most surviving genetic material comes from the bones and teeth of animals that lived in cold environments, where freezing temperatures help ...
Phys.org / Crab-dug tunnels boost methane-eating microbes in coastal wetlands, study finds
Wetlands are a significant producer of methane, a greenhouse gas more potent than carbon dioxide. Yet not all of it escapes into the atmosphere. One reason is crabs. A study published in the journal Environmental Science ...
Phys.org / Asteroid with unexplained orbital shift turns out to be a 'dark comet'
Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. ...
Phys.org / Faster quantum computers can learn from their own mistakes
Quantum computers promise to solve problems that would take even the fastest conventional supercomputers a vast amount of time, but the quantum information they store and process is extremely sensitive to even tiny disturbances ...
Phys.org / GRS 0917+75 is a giant radio galaxy, observations find
European astronomers have conducted optical and radio observations of an enigmatic radio source designated GRS 0917+75. As a result, they found that GRS 0917+75 is a giant radio galaxy and determined its properties. The new ...
Phys.org / Model highlights patterns in how humans move across different locations
Every day, billions of people travel from their homes to work, schools, health care facilities, restaurants, public venues and other destinations. The complex patterns that shape how people move between these different locations ...
