AI breakthrough could revolutionize how we research dinosaur fossils

One of the most promising applications of artificial intelligence technologies is the identification of tumors from high-resolution medical imagery. Can the same techniques be used to help paleontologists more quickly analyze similar scans of dinosaur fossils? Researchers reported some of the early answers—and remaining challenges—in a new paper published in Frontiers in Earth Science.

Culture plays role in children's acceptance of gender-diverse peers

Shown four images of hypothetical peers—a boy playing with cars and trucks, a girl playing with cars and trucks, a boy playing with a Barbie and dollhouse, and a girl playing with a Barbie and dollhouse—children from Thailand and China were then asked a simple question: Would you want to be their friend?

X-rays will make plant diets of the future more tasty

Imagine taking your favorite treat—a Mars bar or cream puff—and beaming it with X-rays to map out what makes it so delicious. Then, picture being able to transfer some of those magnificent qualities and tastes to healthier, more sustainable products.

Getting in gear: Researchers create a slow light device with high optical quality

Researchers including a postdoc at the University of Massachusetts Amherst have created a gear-shaped photonic crystal microring that increases the strength of light-matter interactions without sacrificing optical quality. The result is an on-chip microresonator with an optical quality factor 50 times better than the previous record in slow light devices that could improve microresonators used in...

Will the COVID-19 pandemic make waste management more uncontrollable?

The outbreak of COVID-19 has changed our lifestyle, and even the environment around us, such as the reduction of carbon dioxide and nitrogen dioxide emissions and the alleviation of water pollution. A more obvious change is that the production of waste related to pandemic prevention has increased significantly. For example, the main component of disposable masks we use every day is plastic fiber....

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous to the water pushing on a dam that blocks the stream, light pushes onto and attracts objects that make the light bend. This so-called optical force can be designed to point to a...

Learning loss must be recovered to avoid long-term damage to children's wellbeing and productivity, new report says

School closures have caused large and persistent damage to children's learning and well-being, the cost of which will be felt for decades to come, according to a new report launched today by the Global Education Evidence Advisory Panel (GEEAP), co-hosted by the UK's Foreign, Commonwealth & Development Office, UNICEF Office of Research-Innocenti, and the World Bank.

Universal sex differences appear in adolescents' career aspirations, study finds

A new analysis by David Geary at the University of Missouri and Gijsbert Stoet at the University of Essex in the United Kingdom finds career aspirations from nearly 500,000 adolescents shows consistent sex differences across 80 nations, suggesting biologically-influenced preferences can play a role in gender segregation in the workplace later in life. The researchers also found a tendency for...

Scientific hardware, experiments return to Earth on SpaceX CRS-24 Dragon

A retired microscope and samples from studies on colloids and cellular signaling are among the cargo returning from the International Space Stationaboard the 24th SpaceX commercial resupply services mission. The Dragon craft, which arrived at the station Dec. 22, 2021, was scheduled to undock Jan. 22 with splashdown the next afternoon off the coast of Florida.

Ice-age remains near Sea of Galilee show ancient residents thrived as ice melted

A new article published today in PLOS ONE by a Hebrew University of Jerusalem (HU)'s Institute of Archaeology team and colleagues focused on the remains of a previously submerged fisher-hunter-gatherer camp on the shores of the Sea of Galilee from around 23,000 years ago. Through a close analysis of the abundance, variety and through use of animal remains, the team concluded that these survivors...

Cultural differences impact the evaluation of creativity

Researchers from HSE University have found that people from different cultures evaluate other people's creativity differently. Russians tend to believe that the more unusual a drawing is, the more creative it is, while participants from the United Arab Emirates tend to believe just the opposite. The paper was published in Frontiers in Psychology.
