The instability at the beginning of the solar system — ScienceDaily

Michigan State University’s Seth Jacobson and colleagues in China and France have unveiled a new theory that could help solve a galactic mystery of how our solar system evolved. Specifically, how did the gas giants — Jupiter, Saturn, Uranus and Neptune — end up where they are, orbiting the sun like they do? The research … Read more

Researchers update measurement ratios key for inertial confinement fusion experiments

Graphic A depicts the experimental layout, a carbon puck is mounted to the front face of the GCD-3, a commonly used γ diagnostic at ICF facilities. The γ rays produced in the implosion arrive at the detector first. Later in time, neutrons produced in the fusion can inelastically scatter in the carbon sample to produce … Read more

Using satellite data to help direct response to natural disasters

Credit: Unsplash/CC0 Public Domain Researchers have developed a way to use satellite imaging data to create 3D images that could quickly detect changes on the Earth’s surface, a new study says. The tool could be used to detect significant natural disasters in remote regions of the globe soon after they happen, giving first responders accurate … Read more

New solvent simplifies industrial 3D, roll-to-roll carbon nanotube printing

A composite video shows the various ways rice University researchers are processing carbon nanotubes with a new solvent. The solvent simplifies production of nanotube fibers but also makes possible nanotube films and roll-to-roll production, as well as nanotube inks for 3D and silk screen printing.

Do zoom meetings kill creativity?

Zoom meetings became the lifeblood of many workplaces during the pandemic, but a new study points to a downside: They may limit employees’ capacity for creative thinking. In experiments with workers in several countries, researchers found two broad phenomenon: Coworkers tended to be less adept at generating creative ideas when they communicated by video, versus … Read more
