Physics news

Why solar axions cannot explain the observed XENON1T excess

For several decades, physicists and astrophysicists have theorized about the existence of dark matter in the universe. This elusive type of matter would be made up of particles that do not absorb, reflect or emit light, and that hence cannot be detected using conventional instruments for observing particles.

Physicists suggest mechanism responsible for the neutron drip line is related to deformation

A team of physicists affiliated with several institutions in Japan and one in Belgium has theorized that one of the mechanisms responsible for the neutron drip line is related to deformation. In their paper published in the journal Nature, the group describes their calculations regarding the contributions to binding energy for deformations in nuclei as part of an effort to better understand how many neutrons an atom can hold.

Physicists develop efficient modem for a future quantum internet

The first quantum revolution brought about semiconductor electronics, the laser and finally the internet. The coming, second quantum revolution promises spy-proof communication, extremely precise quantum sensors and quantum computers for previously unsolvable computing tasks. But this revolution is still in its infancy. A central research object is the interface between local quantum devices and light quanta that enable the remote transmission of highly sensitive quantum information. The Otto-Hahn group "Quantum Networks" at the Max-Planck-Institute of Quantum Optics in Garching is researching such a "quantum modem". The team has now achieved a first breakthrough in a relatively simple but highly efficient technology that can be integrated into existing fiber optic networks. The work is published this week in Physical Review X.

New technology allows cameras to capture colors invisible to the human eye

New research from Tel Aviv University will allow cameras to recognize colors that the human eye and even ordinary cameras are unable to perceive.

Researchers shrink imaging spectrometer without compromising performance

Researchers have developed a new imaging spectrometer that is much lighter and smaller than state-of-the-art instruments while maintaining the same high level of performance. Because of its small size and modular design, the new instrument is poised to bring this advanced analytical technique to airborne vehicles and even planetary exploration missions.

Noise reduction via intermittent control by utilizing a plasma actuator

A research team in the Department of Mechanical Engineering at Toyohashi University of Technology developed a method for reducing aerodynamic noise via plasma. Cavity flow, such as the flow around car gaps of high-speed trains, often radiates aerodynamic noise. A plasma actuator inducing flow was applied to suppress this noise. By periodically switching off the power of the plasma actuator, a higher reduction in sound pressure level was observed when compared with continuous operation under the same power consumption.

Blue phosphorus: How a semiconductor becomes a metal

The chemical element phosphorus is considered one of the most essential elements for life. Phosphorus compounds are deeply involved in the structure and function of organisms. Every human carries about one kilogram of it in the body. But even outside our bodies we are surrounded by phosphates and phosphonates every day: in our food, in detergents, fertilizers or in medicines.

Astronomy and Space news

Study investigates dual nuclei in the galaxy merger remnant Mrk 212

Using the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT), astronomers have conducted multi-wavelength observations of a galaxy merger remnant known as Mrk 212. Results of this observational campaign, presented in a paper published October 28 on arXiv.org, shed more light on the properties and nature of this remnant.

The International Space Station at 20 offers hope and a template for future cooperation

On Nov. 2, 2020, the International Space Station celebrated its 20th anniversary of continuous human occupation. With astronauts and cosmonauts from around the world working together, the ISS has demonstrated humankind's ability to not only live and work in space but cooperate with one another. This remarkable achievement is significant as countries and companies around the world look to expand space exploration beyond Earth orbit.

Technology news

Next-generation computer chip with two heads

EPFL engineers have developed a computer chip that combines two functions—logic operations and data storage—into a single architecture, paving the way to more efficient devices. Their technology is particularly promising for applications relying on artificial intelligence.

Scientists develop energy-saving 'liquid window'

Scientists at the Nanyang Technological University, Singapore (NTU Singapore) have developed a liquid window panel that can simultaneously block the sun to regulate solar transmission, while trapping thermal heat that can be released through the day and night, helping to reduce energy consumption in buildings.

Lithium-ion battery research 'flowers'

Lithium-ion batteries work by shuffling lithium ions between a positive electrode (cathode) and a negative electrode (anode) during charging and in the opposite direction during discharging. Our smartphones, laptops, and electric vehicles conventionally employ lithium-ion batteries with anodes made of graphite, a form of carbon. Lithium is inserted into graphite as you charge the battery and removed as you use the battery.
