A new computer model explores how proteins are controlled 'at a distance'

EPFL scientists have created a new computer model that can help better design of allosteric drugs, which control proteins "at a distance".

NASA to Host News Conference on Discovery Beyond Our Solar System

NASA will hold a news conference at 1 p.m. EST Wednesday, Feb. 22, to present new findings on planets that orbit stars other than our sun, known as exoplanets. The event will air live on NASA Television and the agency's website.

Group introduces six new particles to standard model to solve five enduring problems

(Phys.org)—A quartet of researchers has boldly proposed the addition of six new particles to the standard model to explain five enduring problems. In their paper published in the journal Physical Review Letters, Guillermo Ballesteros with Université Paris Saclay, Javier Redondo with Universidad de Zaragoza, Andreas Ringwald with Max-Planck-Institut für Physik and Carlos Tamarit with Durham University describe the six particles they would like to add and why.

Controlling friction levels through on/off application of laser light

A National Institute for Materials Science (NIMS) research group discovered that the amount of friction force between organic molecules and a sapphire substrate in a vacuum can be changed repeatedly by starting and stopping laser light irradiation.

Historic detection of gravitational waves

A scientist who has been involved with nearly every aspect of the development and ultimate success of the Laser Interferometer Gravitational-wave Observatory (LIGO), will give a talk about the project's historic detection of gravitational waves.

NASA Cargo Headed to Space Station Includes Important Experiments, Equipment

Major experiments that will look into a range of scientific disciplines from human health to atmospheric conditions on Earth are on their way to the International Space Station following liftoff at 9:39 a.m. EST aboard a SpaceX Falcon 9 rocket.

Designing new materials from 'small' data

Researchers have developed a novel workflow combining machine learning and density functional theory calculations to create design guidelines for new materials that exhibit useful electronic properties, such as ferroelectricity and piezoelectricity.

NASA’s Juno Mission to Remain in Current Orbit at Jupiter

NASA’s Juno mission to Jupiter, which has been in orbit around the gas giant since July 4, 2016, will remain in its current 53-day orbit for the remainder of the mission.

Breakthrough with a chain of gold atoms in understanding heat transport

The precise control of electron transport in microelectronics makes complex logic circuits possible that are in daily use in smartphones and laptops.

NASA to Televise International Space Station Cargo Ship Launch, Docking

NASA Television will provide live coverage of the launch and docking of a Russian cargo spacecraft delivering almost three tons of food, fuel and supplies to the International Space Station beginning at 12:30 a.m. EST Wednesday, Feb. 22.
