Researchers use AI to discover New Planet outside Solar System

The exoplanet was detected using machine learning, a branch of artificial intelligence

A University of Georgia research team has confirmed evidence of a previously unknown planet outside of our solar system, and they used machine learning tools to detect it.

A recent study by the team showed that machine learning can correctly determine if an exoplanet is present by looking in protoplanetary disks, the gas around newly formed stars.

The newly published findings represent a first step toward using machine learning to identify previously overlooked exoplanets.

“We confirmed the planet using traditional techniques, but our models directed us to run those simulations and showed us exactly where the planet might be,” said Jason Terry, doctoral student in the UGA Franklin Colleg...

Embracing Variations: Physicists analyze noise in Lambda-type Quantum Memory

Embracing variations: UIUC physicists first to analyze noise in Lambda-type quantum memory
The quantum memory experiment Shinbrough and Lorenz are constructing. It is a cell designed to hold hot metallic vapor, an example of the Lambda-type optical quantum memories that the researchers analyzed.

New Passive Device continuously Generates Electricity during the Day or Night

New passive device continuously generates electricity during the day or night
The new self-powered thermoelectric generator device uses an ultra-broadband solar absorber (UBSA) to capture sunlight, which heats the generator. Simultaneously, another component called a planar radiative cooling emitter (RCE) cools part of the device by releasing heat. Credit: Haoyuan Cai, Jimei University

Researchers have developed a new thermoelectric generator (TEG) that can continuously generate electricity using heat from the sun and a radiative element that releases heat into the air. Because it works during the day or night and in cloudy conditions, the new self-powered TEG could provide a reliable power source for small electronic devices such as outdoor sensors.

“Traditional power sources like batteries are limited in capacity and require regular replacement or rechargin...
