On-demand hydrogen fuel production goes dark-mode

Hydrogen, the lightest element on the periodic table, is a master of escaping almost any container it’s stored in. Its extremely small size allows it to squeeze through atomic-scale gaps in the storage materials, which is one of the major issues hindering hydrogen energy from becoming mainstream.

A team of Chinese researchers has solved the issue of containment with on-demand hydrogen production. They developed a simple chemical system containing commercial ammonium metatungstate (W12) and graphitic carbon nitride (g-C3N4) in a liquid suspension. This system captures solar energy and, rather than converting it into electricity, uses it to produce hydrogen fuel on demand—even in darkness.

The new system provided twofold benefits: it made solar energy available even when the sun isn’t shining, and it eliminated the need to transport hydrogen in dangerous, high-pressure tanks.

Creating cells that help the brain keep its cool

Researchers at Lund University in Sweden have created a method that makes it possible to transform the brain’s support cells into parvalbumin-positive cells. These cells act as the brain’s rapid-braking system and are significantly involved in schizophrenia, epilepsy and other neurological conditions.

Parvalbumin cells play a central role in keeping brain activity in equilibrium. They control nerve cell signaling, reduce overactivity and make sure that the brain is working to a rhythm. Researchers sometimes describe them as the cells that “make the brain sound right.”

When these cells malfunction or decrease in number, the balance of the brain is disrupted. Previous studies suggest that damaged parvalbumin cells may contribute to disorders such as schizophrenia and epilepsy.

Quantum spins team up to create stable, long-lived microwave signals

When quantum particles work together, they can produce signals far stronger than any one particle could generate alone. This collective phenomenon, called superradiance, is a powerful example of cooperation at the quantum level. Until now, superradiance was mostly known for making quantum systems lose their energy too quickly, posing challenges for quantum technologies.

But a new study published in Nature Physics turns this idea on its head—revealing that collective superradiant effects can instead produce self-sustained, long-lived microwave signals with exciting potential for future quantum devices.

“What’s remarkable is that the seemingly messy interactions between spins actually fuel the emission,” explains Dr. Wenzel Kersten, first author of the study. “The system organizes itself, producing an extremely coherent microwave signal from the very disorder that usually destroys it.”

Study unveils the dual nature of a young stellar object

Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have conducted a long-term photometric and spectroscopic study of a young stellar object known as V1180 Cassiopeiae. Results of the study, published December 23 on the arXiv preprint server, unveil the dual nature of this object.

Young stellar objects (YSOs) are stars in the early stages of evolution; in particular, protostars and pre-main sequence (PMS) stars. They are usually observed embedded in dense molecular clumps, environments containing plenty of molecular gas and interstellar dust.

Given that episodic accretion processes occur in YSOs, these objects may experience accretion-driven outbursts. Astronomers usually divide such events into EX Lup (also known as EXors) and FU Ori outbursts (or FUors). EXors are a few magnitudes in amplitude, and last from a few months to one or two years. FUors are more extreme and rare as they can be up to 5–6 magnitudes in amplitude and last from decades to even centuries.

A 30-Year Physics Mystery Takes a Sharp Turn: This Bizarre Particle Doesn’t Actually Exist

New results from the MicroBooNE experiment rule out the existence of a sterile neutrino, reshaping how scientists think about long-standing neutrino anomalies. After many years of investigation, researchers working on the Micro Booster Neutrino Experiment (MicroBooNE) have concluded that a propos

Astronomers Measure The Mass of a Planet With No Star For The First Time

Not all planets are lucky enough to live in a neighborhood like our Solar System – some are doomed to roam the cosmos alone. Astronomers have now, for the first time, measured the mass of, and distance to, one of these lonely worlds.

The planet packs about a fifth of the mass of Jupiter, and is located a little under 10,000 light-years away from Earth, towards the center of our galaxy. That size suggests it most likely formed as part of a planetary system, before being exiled by a game of gravitational billiards.

NASA Confirms It Has Lost Contact With Mars Orbiter MAVEN

NASA has officially lost contact with a spacecraft that has been orbiting Mars since 2014.

The MAVEN spacecraft – Mars Atmosphere and Volatile Evolution – abruptly lost contact with Earth on 6 December 2025 while passing behind the red planet in the normal course of its orbit. When MAVEN re-emerged from behind Mars, however, NASA ground control was unable to reestablish a connection.

On December 9, the space agency announced it is investigating the issue and attempting to locate a signal.

Transparent Tribe Launches New RAT Attacks Against Indian Government and Academia

The threat actor known as Transparent Tribe has been attributed to a fresh set of attacks targeting Indian governmental, academic, and strategic entities with a remote access trojan (RAT) that grants them persistent control over compromised hosts.

“The campaign employs deceptive delivery techniques, including a weaponized Windows shortcut (LNK) file masquerading as a legitimate PDF document and embedded with full PDF content to evade user suspicion,” CYFIRMA said in a technical report.

Transparent Tribe, also called APT36, is a hacking group that’s known for mounting cyber espionage campaigns against Indian organizations. Assessed to be of Indian origin, the state-sponsored adversary has been active since at least 2013.
