Strange cosmic burst from colliding galaxies shines light on heavy elements

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely caused by the collision of two neutron stars hundreds of millions of years ago and is now shedding light […]

Miniature laser technology could bring lab testing into your home

A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, which could move testing from hospitals to patients’ homes. This, in turn, would free up hospital beds and reduce visits to clinics.

Evaluating landing sites for China’s manned moon mission

Observations of the Rimae Bode region on the moon reveal five distinct types of terrain and identify several potential landing sites for China’s first crewed mission, according to research titled “Geology of Rimae Bode region as priority site candidate for China’s first crewed lunar mission.” The work is published in Nature Astronomy.

How do we know what asteroids are made out of?

Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling from dust and rock. They’re time capsules, preserving clues about what the early solar system was like, and, ultimately, what the building blocks of planets are.

In search of a room-temperature superconductor, scientists present a research agenda

The search for materials that can conduct electricity at room temperature without losing energy is one of the greatest and most consequential challenges of modern physics: loss-free power transmission, more efficient motors and generators, more powerful quantum computers, cheaper MRI devices. Hardly any other material discovery has the potential to change so many areas of […]

Nanosecond light-by-light switching achieved in liquid crystal droplet

Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into electrical signals, potentially enabling faster and more energy-efficient devices. In recent years, researchers have begun exploring an unexpected platform for this purpose: soft matter.

Terraforming Mars isn’t a climate problem—it’s an industrial nightmare

Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion—we’re not going to be able […]

Ultrafast light pulses make molecules rotate on quantum materials

Researchers from Germany, Japan and India, led by scientists from DESY and the Universities of Kiel and Hamburg, have found a way to collectively make molecules on a flat surface rotate by exposing them to light using ultrafast light pulses from DESY’s free-electron laser FLASH and a high-harmonic generation source. However, making those molecules dance […]

Nearby red dwarf star hosts at least four planets—with one in the habitable zone

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. The new study suggests that one of these newly confirmed planets is in the habitable zone.

Record-energy neutrino may have begun its journey in blazars

Three years ago, in the waters of the Mediterranean Sea, the passage of an “ultra-energetic” cosmic neutrino was observed—the most energetic ever detected. The event drew international attention from the scientific community as well as from the media and the public, not least because the origin of this particle—whose energy exceeded that of previously observed […]
