Spotify removes Neil Young music in feud over Joe Rogan’s false Covid claims

Musician condemned spread of misinformation on platform’s top podcast: ‘They can have Rogan or Young’The music streaming platform Spotify is in the process of removing Neil Young’s music after the company refused to take down Joe Rogan’s podcast amid the musician’s objections that it spread vaccine misinformation.Rogan has been described by the New York Times as “one of the most...

Fossil snail shells offer new tool for analyzing ancient ocean chemistry

A collection of fossil shells from marine snails and clams is challenging a theory that says the world's deadliest mass extinction was accompanied by severe ocean acidification. The study is the first to use shells from fossilized mollusks to investigate ocean chemistry, demonstrating a new tool that scientists can use to study the conditions of the planet's deep past.

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

Researchers 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 a range of photonics applications, including sensing and...

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...

The James Webb Space Telescope Is in Position—And Now We Wait

The James Webb Space Telescope traveled nearly 1.6 million km (1 million mi.) to reach a destination that, in some ways, is nowhere at all. On Jan. 24, just shy of one month after its Christmas Day launch, the $10 billion observatory arrived at a spot in space known as L2—where the gravity of the sun and the Earth effectively cancel each other out, allowing the spacecraft to circle an...
