Last chance for WIMPs: physicists launch all-out hunt for dark-matter candidate

Posted by in category: particle physics

Over the coming months, operations will begin at three existing underground detectors — in the United States, Italy and China — that search for dark-matter particles by looking for interactions in supercooled vats of xenon. Using a method honed over more than a decade, these detectors will watch for telltale flashes of light when the nuclei recoil from their interaction with dark-matter particles.

Researchers have spent decades searching for the elusive particles — a final generation of detectors should leave them no place to hide.

New Experiments Headed to the Space Station: Radishes, Advanced Imaging, and Liquid Metal

Posted by in category: space

Science typically begins with a question. It may be: “How will astronauts maintain a nutritious diet on long-duration missions?” Or “How can the way metals are made be improved by studying them in space?” These are just two of the questions researchers seek to answer with the upcoming launch of new research, technology demonstrations, and commercial products headed to our unique microgravity laboratory orbiting Earth.

NASA uses the spaceflight environment to further our understanding of how to successfully live and work in space. These space experiments help us understand the effects of radiation, microgravity and other factors on life and physical systems. It is also an important aspect in understanding how to sustain life on the Moon and eventually Mars.

On Friday, October 2, 2020, at 9:16 p.m. EDT, new space experiments and a new space toilet launched on Northrop Grumman’s 14th commercial resupply mission for the agency to the International Space Station.

Summary: A patient who suffered brain injury can temporarily walk, talk, and recognize family members thanks to the sleep medication Zolpidem.

Source: Radboud University

A patient who could not move and talk spontaneously for eight years started to do so again after being administered a sleeping pill. The spectacular but temporary effect was visualized with brain scans, giving researchers from Radboud university medical center and Amsterdam UMC a better understanding of this disorder’s underlying neurophysiological processes. The article has been published in Cortex.

A Technion student has just smashed the world record for light resonance

Posted by in categories: engineering, physics

They can be made up of just two surfaces, bouncing the wave between them, but the more surfaces that are added, the more resonance is achieved. The ultimate is therefore to create a perfect sphere, creating surfaces in every direction within a three-dimensional object. At that point, the creation of a resonator moves from being a physics question to one of engineering, since even a stem holding the sphere can create distortion that reduces the impact of the resonator.

According to the Technion, the world’s first micro-resonator was demonstrated in the 1970s by Arthur Ashkin, winner of the 2018 Nobel Prize in Physics, who presented a floating resonator. Yet, despite the success of his innovation, the research direction was soon abandoned.

Now graduate student Jacob Kher-Alden, under the supervision of Prof. Tal Carmon, has built upon Ashkin’s work, creating a floating resonator which can exhibit resonant enhancement by ten million circulations of light, compared to about 300 circulations in Ashkin’s resonator.
