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 / 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 / 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 / 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 / Doughnut‑shaped topology reveals new way to classify knitting, crochet and other textiles
Fabrics are made by repeatedly intertwining yarns into characteristic patterns. Many of their properties, such as stretchiness, arise not only from the material itself but also from how the yarns are arranged and entangled. ...
Phys.org / When disaster strikes, people often flee to places that feel familiar
When the Marshall Fire tore through suburban Colorado in late 2021, residents had only hours to decide where to go. Some fled to nearby towns. Others stayed farther away for weeks or months. Now, a recent study published ...
Phys.org / Astronomers find nearby planets to be small, strange, and utterly uninhabitable
Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard's Star—the sun's closest neighbor after Alpha Centauri, just under six light-years from Earth.
Phys.org / Unhoused people and wildlife are increasingly coming into contact. Here's what can be done to protect them
As homelessness increases around the world, more unhoused people are turning to parks and other urban green spaces to seek shelter. However, these places are also home to animals that live in and around urban areas.
Phys.org / Microplastics reach even 2,000 meters below the ocean surface, study finds
Plastic pollution has become a global environmental crisis, with an estimated 11 million tons of plastic entering the oceans each year. As larger plastic debris breaks down into microplastics, these tiny particles are transported ...
Phys.org / Striking new species of African monkey discovered deep in the Congo rainforest
In the rainforests of the Democratic Republic of Congo (DRC), scientists have identified a previously unknown species of African monkey—one of the rarest discoveries in modern primatology.
Phys.org / Adolescent social media restrictions may reduce some harms while shifting others, warn experts
Amrit Kaur Purba and colleagues argue that social media restrictions operate within a wider system of adolescents, families, schools, governments and commercial actors—and therefore should be treated as complex systems interventions ...
