Tritium-infused graphene could sharpen the hunt for neutrino mass

While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, pinning down exactly how much has proven extraordinarily difficult.

MeerKAT discovers 15 new millisecond pulsars in a well known globular cluster

Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest issue of Astronomy & Astrophysics.

Indigenous Australians were the world’s first astronomers. But their knowledge is now at risk

I’m a proud Yorta Yorta and Barapa Barapa man, an Indigenous astronomer and a trainee ecologist. When I look at the night sky, I don’t just see stars. Instead, I see an ancient knowledge system that has guided people, culture and Country for tens of thousands of years.

Consistency check casts doubt on evolving dark energy

Cosmologists have long struggled to determine whether the universe’s accelerating expansion is being driven by a simple cosmological constant, or whether dark energy’s influence is evolving over time. In a new analysis published in Physical Review D, Samsuzzaman Afroz and Suvodip Mukherjee at the Tata Institute of Fundamental Research, Mumbai, have identified a subtle impact […]

Asteroid 2022 OB5 spins too fast for current prospectors, highlighting the divide between ‘accessible’ and ‘exploitable’

Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility. But in practice, it is certainly not that simple, and a new paper from some Spanish researchers, published in […]

Busseiron and the formation of a discipline in Japanese physics

The middle of the twentieth century was a period of significant scientific advancement, particularly in the realm of physics. Within this rapidly changing landscape, academic disciplines emerged and evolved to keep pace with scientific discoveries. The new subdiscipline of solid-state physics gained prominence in the United States, but it was later subsumed by the broader […]

SMILE spacecraft launches to capture first X-ray views of Earth’s magnetic shield

A joint European-Chinese spacecraft blasted off into orbit Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth’s magnetic shield.

Mars reveals first Zwan-Wolf effect deep in its atmosphere during a solar storm

In December 2023, scientists looking at Mars data stumbled across something completely unexpected—observations of an atmospheric effect never before seen in the Red Planet’s atmosphere. Using instruments aboard NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission, scientists identified a phenomenon known to occur in Earth’s magnetosphere, where charged particles are squeezed like toothpaste coming out […]

Reconfigurable Ge-Si photodetector achieves ultrahigh-speed data transmission using low-loss packaging

The rapid growth of large language models is placing increasing demands on data centers, where large volumes of data must be transferred efficiently between servers. Optical interconnects are essential for enabling this communication, but as data rates continue to rise, these systems must deliver higher bandwidth while maintaining low latency and energy efficiency. However, integrating […]

The structure of water: Entropy determines whether ions stick

Water molecules do not simply swirl around in complete disorder; they can form certain preferred structures. This scientific fact is often presented in entirely unscientific ways. For example, when people speak of an alleged “memory of water” or of “water clusters” as a possible explanation for homeopathy, among other things.

The Underwater Alien Bases That Destroy Every Vessel That Gets Too Close: Devil’s Sea, Lake Baikal, Catalina

From the Devil’s Sea off Japan to Lake Baikal in Siberia, from the Santa Catalina Channel off California to the Pacific waters where the USS Omaha confronted a transmedium craft — there are bodies of water where vessels do not return. The pattern, and the casualty record, points to one conclusion: there are bases […]
