First topological quantum simulator device in strong light-matter interaction regime to operate at room temperatures

Researchers at Rensselaer Polytechnic Institute have fabricated a device no wider than a human hair that will help physicists investigate the fundamental nature of matter and light. Their findings, published in the journal ...

New Saturn-mass exoplanet detected by astronomers

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new Saturn-mass planet orbiting a solar-type star known as TOI-2447. The finding was reported in a research ...

Birth of universe's earliest galaxies observed for first time

Using the James Webb Space Telescope, University of Copenhagen researchers have become the first to see the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery ...

Crows can deliberately plan how many calls to make, study shows

In a behavioral experiment, crows were able to learn to produce a set number of calls. This involves them planning in advance. From the sound of the first call in a numerical sequence, it is possible to predict how many calls ...

Poor access to essential surgery is costing lives, says study

Inadequate access to simple elective surgery in developing countries is storing up future health problems for patients and may create a spiral of future health complications putting more people's lives at risk, a new study ...

Birdsong and human voice built from same genetic blueprint

Humans have long been fascinated by bird song and the cacophony of other avian sounds—from coos and honks to quacks and peeps. But little is known about how the unique vocal organ of birds—the syrinx—varies from species ...

Agreement reached at UN on biopiracy treaty

More than 190 nations agreed Friday on a new treaty to combat so-called biopiracy and regulate patents stemming from genetic resources such as medicinal plants, particularly ones whose uses owe a debt to traditional knowledge.

The value of failure in conservation programs

Conservation programs need—and often incentivize—community involvement. For example, a program in Zanzibar, Tanzania, asked communities to protect their village forests in exchange for access to the carbon credits market. ...

Could alien solar panels be technosignatures?

If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it's the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, ...

Finding the age of a contact binary 'moon'

There are millions of asteroids floating around the solar system. With so many of them, it should be no surprise that some are weirdly configured. A recent example of one of these weird configurations was discovered when ...
