New research shows that nearly 28% of all electric scooters reported injuries were head and neck injuries.

Probing the dynamics of photoemission

Posted: 17 Jun 2021 11:58 AM PDT

Physicists have used ultrashort laser pulses to probe the dynamics of photoelectron emission in tungsten crystals.

Novel chirped pulses defy 'conventional wisdom'

Posted: 17 Jun 2021 10:38 AM PDT

Researchers demonstrate highly chirped pulses created by a using a spectral filter in a Kerr resonator, enabling them to widen a laser pulse wavefront by separating the beam's colors. The chirped pulses remain stable even with more than 90% energy loss.

Hubble data confirms galaxies lacking dark matter

Posted: 17 Jun 2021 08:55 AM PDT

The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs are based on 40 orbits of NASA's Hubble Space Telescope, with imaging by the Advanced Camera for Surveys and a 'tip of the red giant branch' (TRGB) analysis.

A remote control for gene transfer

Researchers develop technology to introduce genes into single cells in a targeted manner.

A new 'twist' to break viscoelastic liquid bridges

Posted: 17 Jun 2021 08:52 AM PDT

Scientists have developed a new method that improves dispensing of viscoelastic fluids - a vital process for circuit board production, 3D printing and other industrial applications. The scientists found that twisting these liquid bridges breaks them in a quicker and cleaner way than the conventional method of stretching them.

Study of young chaotic star system reveals planet formation secrets

Posted: 17 Jun 2021 07:12 AM PDT

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation.

Defining the Hund physics landscape of two-orbital systems

Posted: 17 Jun 2021 07:12 AM PDT

Electrons are ubiquitous among atoms, subatomic tokens of energy that can independently change how a system behaves -- but they also can change each other. An international research collaboration found that collectively measuring electrons revealed unique and unanticipated findings.

AI system-on-chip runs on solar power

Posted: 17 Jun 2021 05:27 AM PDT

Engineers have developed an integrated circuit that can carry out complicated artificial-intelligence operations like face, voice and gesture recognition and cardiac monitoring. Powered by either a tiny battery or a solar panel, it processes data at the edge and can be configured for use in just about any type of application.

New invention keeps qubits of light stable at room temperature

Posted: 17 Jun 2021 05:27 AM PDT

Researchers have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at -270 degrees. Their discovery saves power and money and is a breakthrough in quantum research.
