Physicists magnetize a material with light

Boston MA (SPX) Dec 26, 2024 - MIT physicists have created a new and long-lasting magnetic state in a material, using only light.

In a study appearing in Nature, the researchers report using a terahertz laser - a light source that oscillates more than a trillion times per second - to directly stimulate atoms in an antiferromagnetic material. The laser's oscillations are tuned to the natural vibrations among the material's atoms, in a way that shifts the balance of atomic spins toward a new magnetic state. Читать дальше...

Nanotechnology Discovery Unlocks Unique Molecular Interactions Using Light

Paris, France (SPX) Dec 28, 2024 - Researchers at the University of Bologna, led by Prof. Alberto Credi, have developed an innovative method to manipulate molecular assembly using light energy. This approach allows for the creation of a molecular configuration that defies the natural thermodynamic equilibrium, a feat previously considered unattainable.

"We have shown that by administering light energy to an aqueous solution, a molecular self-assembly reaction can be prevented from reaching a thermodynamic minimum... Читать дальше...

Northern lights to ring in New Year's Eve in parts of United States

Washington DC (UPI) Dec 30, 2024 - The northern lights are forecast to put on a New Year's show as far south as Illinois, New York and Oregon starting Monday night, according to the National Oceanic and Atmospheric Administration.

The powerful geomagnetic storm, or coronal mass ejection of solar material, is classified as a strong warning G3 that could produce northern lights visible through New Year's Eve in as many as 18 states.

Sun emits three powerful solar flares

Los Angeles CA (SPX) Dec 31, 2024 - The Sun unleashed three significant solar flares on December 29, 2024, recorded at peak times of 2:18 a.m. ET, 11:14 p.m. ET, and 11:31 p.m. ET. These events were documented by the Solar Ultraviolet Imager operated by the National Oceanic and Atmospheric Administration (NOAA), a continuous observer of solar activity.

Solar flares, potent bursts of energy from the Sun, have the potential to disrupt radio communications, impact power grids, affect navigation systems... Читать дальше...

OpenAI outlines plans to becoming for-profit company

Washington (AFP) Dec 27, 2024 - ChatGPT-maker OpenAI laid out plans Friday for a new corporate structure shifting away from control by a non-profit -- an issue of contention for the artificial intelligence trailblazer.

OpenAI was founded as a non-profit in 2015 and has since switched to a "capped" for-profit enterprise allowing for a limited level of money making.
