A sub-zero elastocaloric freezer by HKUST achieves -12℃ with zero emissions, offering sustainable, energy-efficient cooling for the global freezing market.

Researchers at Sweden’s Chalmers University of Technology suggest that frozen hydrogen cyanide may have helped trigger the chemistry that led to life on Earth. Their simulations show HCN forming cobweb-like ice crystals whose reactive surfaces enable unusual chemical reactions even in extreme cold. These processes could generate amino acids, nucleobases and other es...

New observations from the Dark Energy Spectroscopic Instrument are challenging the standard Lambda-CDM model of cosmology. A recent, still-unpublished hypothesis suggests that space itself may behave like a slightly viscous or “sticky” fluid, subtly affecting how the universe expands. By introducing a ghostly resistance to cosmic growth, the model could reconcile ...

NASA has confirmed that the three-member Expedition 74 crew will continue operations aboard the International Space Station following the early return of SpaceX Crew-11. U.S. astronaut Chris Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev are carrying out scientific experiments and routine maintenance while awaiting the arrival of four new crewm...

ESA suffered cyberattacks that exposed hundreds of gigabytes of sensitive data, including mission details, access credentials, and proprietary software. While no immediate threat is reported, cybersecurity experts warn that combined leaks could pose strategic risks. The agency is cooperating with authorities, highlighting the need for stronger cybersecurity in the spa...

SETI scientists are using China’s FAST radio telescope to examine the final 100 unexplained signals from the historic SETI@home project. While experts expect most to be radio interference, the search marks the culmination of a massive global citizen science effort and sets new standards for future hunts for extraterrestrial intelligence.

NASA is preparing for a historic crewed lunar mission as the Artemis II rocket rolls to its launch pad this Saturday. The massive Space Launch System and Orion capsule will carry four astronauts on a Moon flyby, marking a critical step toward sustained lunar exploration and future missions to Mars.

Hypothetical dark stars could explain three early universe mysteries: the abundance of supermassive black holes, dense blue monster galaxies, and compact little red dots. Powered by dark matter rather than fusion, these stars may have formed before normal stars, collapsing to create black hole seeds and influencing early galaxy observations, according to research publ...

Mysterious “little red dots” spotted by the James Webb Space Telescope may not be tiny galaxies after all. A new study suggests they are supermassive black holes wrapped in dense gas and dust, perfectly disguised in the early universe and shining intensely in infrared light.

NASA’s latest global temperature analysis shows Earth remained extremely warm in 2025, nearly matching 2023 levels. Although cooler than record-setting 2024, last year ranked as the third warmest since 1880. Independent climate agencies worldwide reported similar results, reinforcing evidence of a persistent and long-term global warming trend.
