Using observations from multiple powerful telescopes, a team of astronomers studied a red quasar nicknamed "the Hatchling" at redshift 3.7. They may have identified one of the clearest examples yet of a quasar caught in transition ...

Microplastics have become nearly impossible to avoid. They have been detected in oceans, drinking water and even the human body, but scientists are still uncovering how they affect human health. Now, researchers at the Texas ...

Using light to process quantum information is one of the most promising approaches to building future quantum computers. Light particles, known as photons, are excellent carriers of quantum information, but their lack of ...

What shape is an asteroid? For (44) Nysa, the honest answer until now has been that nobody knew. It is one of the brightest and largest E-type asteroids in the main belt, a class with a surface rich in enstatite, and its ...

Researchers used to think that HIV and its relatives were pretty recent things, maybe only a few hundred years old. But a growing body of evidence now suggests their history is far more ancient, with viruses closely related ...

The way women are screened for breast cancer in Australia is changing. According to a newly released review, this means moving away from screening based largely on someone's age. Instead, screening would be tailored according ...

For the first time, researchers have determined the shape of the actinide nucleus of fermium-255 and measured its structure with high precision and resolution.

Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...

When people work in pairs or teams, they can often solve a wider range of problems, completing some tasks faster and more efficiently than they would alone. To assist users similarly to how other humans would, robots should ...

A new study led by a Duke University scientist overturns a long-held idea about how primates, including humans, came to have such large and sophisticated brains. The research finds that the dramatic expansion of the primate ...

By rapidly twisting a microscopically small tip back and forth, researchers at the University of Maryland (UMD) have unlocked a new way to detect subtle changes on the surface of a material flexing in response to infrared ...

Oxygen provides the driving force for many vital chemical reactions. Two well-known examples include respiration, the process that allows living things to break down food to release its energy, and combustion, reactions that ...
