Quantum manipulation power for quantum information processing gets a boost

In a new study, researchers present methods for controlling the output power and efficiency of a quantum thermal engine based on a two-atom cavity, where the atoms interact with the light confined within the cavity. This could help improve quantum manipulation power for quantum information processing.

Scientists develop machine-learning method to predict the behavior of molecules

A team of scientists has come up with a machine-learning method that predicts molecular behavior, a breakthrough that can aid in the development of pharmaceuticals and the design of new molecules that can be used to enhance the performance of emerging battery technologies, solar cells, and digital displays.

Marie Curie and her X-ray vehicles' contribution to World War I battlefield medicine

Ask people to name the most famous historical woman of science and their answer will likely be: Madame Marie Curie. Push further and ask what she did, and they might say it was something related to radioactivity. (She actually discovered the radioisotopes radium and polonium.) Some might also know that she was the first woman to win a Nobel Prize. (She actually won two.)

Electrons surfing on a laser beam

The Large Hadron Collider at CERN in Switzerland, the largest accelerator in the world, has a circumference of around 26 kilometres. Researchers at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU), Germany, are attempting to go to the other extreme by building the world's smallest accelerator—one that fits on a microchip. The research team has now taken another step towards achieving this ambition.

NASA Announces Briefing on Carbon Mission Science Results

NASA will hold a media teleconference at 2 p.m. EDT Thursday, Oct. 12, to discuss new research to be published this week on changing global levels of carbon dioxide in the atmosphere. The research is based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission and other satellites.

NASA TV to Broadcast Hispanic Heritage Event

NASA will celebrate Hispanic Heritage Month at the James Webb Auditorium in the agency’s headquarters in Washington on Thursday, Oct. 12, with a discussion of the contributions of Hispanics to NASA’s mission and the importance of Hispanic representation in science, technology, engineering and mathematics (STEM) education and careers.

Machine learning translates 'hidden' information to reveal chemistry in action

Scientists have developed a new way to capture the details of chemistry choreography as it happens. The method -- which relies on computers that have learned to recognize hidden signs of the steps -- should help them improve the performance of catalysts to drive reactions toward desired products faster.

Forget about it: A material that mimics the brain

Inspired by human forgetfulness -- how our brains discard unnecessary data to make room for new information -- scientists conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually 'forgets.' This could one day be used for advanced bio-inspired computing.

The largest particle accelerator in the world - the Large Hadron Collider at CERN in Switzerland -- has a circumference of around 26 kilometers. Researchers are now attempting to go to the other extreme by building the world's smallest machine of this kind -- a particle accelerator that fits on a microchip.
