The LZ experiment’s first science run sets new constraints on dark matter interactions

The LUX ZEPLIN (LZ) Dark Matter experiment is a large research effort involving over 200 scientists and engineers at 40 institutions worldwide. Its key objective is to search for weakly interacting massive particles (WIMPs) by analyzing data collected by the LZ detector, situated at the Sanford Underground Research Facility in South Dakota.

A CubeSat mission will detect X-rays from GRBs and black-hole mergers

The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now to tie signals across multiple domains—for example, a gravitational wave and the associated electromagnetic radiation created by that same event, such as a black hole merger or a gamma-ray burst.

Simulations of supercooled liquid molecular dynamics may lead to higher-quality glass production at lower cost

Glass might seem to be an ordinary material we encounter every day, but the physics at play inside are actually quite complex and still not completely understood by scientists. Some panes of glass, such as the stained-glass windows in many medieval buildings, have remained rigid for centuries, as their constituent molecules are perpetually frozen in […]

NASA eyes SpaceX, Blue Origin to cut Mars rock retrieval costs

NASA announced Tuesday it may turn to Elon Musk’s SpaceX or Jeff Bezos’s Blue Origin to help reduce the soaring costs of returning Martian rocks collected by the Perseverance rover to Earth.

It was in 1927, when Airlines started flying over Peru and the Nazca region that passengers reported strange lines, figures and shapes on the ground.

Airplanes filled with tourists from all over the world quickly conquered the Nazca skies and hundreds of […]

Will Comet G3 ATLAS perform at perihelion?

What “may” be the best anticipated comet of 2025 is coming right up. Right now, there’s only one comet with real potential to reach naked eye visibility in 2025: Comet C/2024 G3 ATLAS. This comet reaches perihelion at 0.094 Astronomical Units (AU, 8.7 million miles or 14 million kilometers, interior to the orbit of Mercury) […]

NASA proposes cheaper, quicker way to get Mars rocks and soil to Earth

NASA is pitching a cheaper and quicker way of getting rocks and soil back from Mars, after seeing its original plan swell to $11 billion.

AI technique generates clear images of thick biological samples without additional hardware

Depth degradation is a problem biologists know all too well: The deeper you look into a sample, the fuzzier the image becomes. A worm embryo or a piece of tissue may only be tens of microns thick, but the bending of light causes microscopy images to lose their sharpness as the instruments peer beyond the […]

Coordinating risk assessments for radiation in outer space

In the next few decades, crewed missions to the moon and Mars will likely become frequent. One of the main challenges faced by these future missions will be the need to protect astronauts from the intense radiation of outer space.

Fabricating single-photon detectors from superconducting aluminum nanostrips

In quantum computers, information is often carried by single photons and picked up by structures named superconducting nanostrip single-photon detectors (SNSPDs). In principle, traditional type-I superconductors would be easier to integrate into existing quantum computing architectures than the type-II materials more widely used today. So far, however, this possibility hasn’t been widely explored.
