Greenland Ice Melt Is Surging Sixfold — Why Scientists Say Sea-Level Risk Is Rising

Greenland’s ice sheet meltwater production has increased sixfold since 1990, with seven of the 10 most extreme melt events occurring after 2000, a University of Barcelona-led study reports. The area affected by extreme melt expanded by 2.8 million square kilometers per decade, and meltwater volume rose from 12.7 to 82.4 gigatons per decade. NASA data show Greenland lost about 264 billion metric tons of ice annually between 2002 and 2025.

Why IonQ Stock Is Back in the Quantum Spotlight After a 755% Sales Surge

Colossal Biosciences says its three gene-edited wolves, modeled on the extinct dire wolf, are healthy and ready to breed. Outside scientists dispute whether the animals qualify as dire wolves. The animals were created using ancient DNA and CRISPR edits to gray-wolf cells, then cloned and born via dog surrogates. The company’s next step is to test if the edited traits pass to offspring.

Chernobyl Fungus Back in Focus as DARPA and Space Claims Revive Radiation-Eating Debate

ScienceAlert and other outlets revived coverage of Chernobyl’s black fungus, Cladosporium sphaerospermum, but researchers have not shown it can convert radiation into usable energy. The fungus, first documented in Chernobyl in 2000, grows faster under radiation and may help shield against it, as seen in ISS experiments. DARPA is moving forward with space manufacturing tests, but links to the fungus remain speculative.

NASA Satellite Re-entry Alert: Van Allen Probe A’s Final Descent Carries Low Risk

The U.S. Space Force now projects NASA’s retired Van Allen Probe A will re-enter Earth’s atmosphere around 12:03 a.m. ET Wednesday, later than NASA’s earlier estimate. Most of the 1,323-pound spacecraft is expected to burn up, with a 1 in 4,200 chance of causing harm on the ground. The probe is falling years early due to increased solar activity. Precise re-entry timing remains uncertain.

NASA Satellite Crash Alert: Van Allen Probe A Set for Earth Re-Entry With Low Risk to People

NASA said its defunct Van Allen Probe A satellite, weighing 1,323 pounds, is expected to re-enter Earth’s atmosphere around 7:45 p.m. EDT Tuesday, with some debris likely to survive. Officials say there is no targeted landing area and the exact timing remains uncertain. The mission ended in 2019, years earlier than planned, after increased solar activity accelerated the craft’s descent. NASA maintains the risk to the public is low.

Haleon PLC’s Centrum Silver May Slow Biological Aging, Nature Medicine Study Finds

A Nature Medicine study found Haleon’s Centrum Silver slowed biological aging markers by about four months over two years in older adults, based on analysis of 958 participants. The effect was statistically significant but small, with authors urging more research. Haleon, facing weak U.S. demand and heavy competition, welcomed the findings but did not influence the trial. The company reported U.S. multivitamin sales rebounded in late 2025.

AI tool aims to match dinosaur footprints to the animals that made them, study says

Researchers unveiled an AI system that analyzes dinosaur footprints, using eight recurring shape traits from 1,974 track silhouettes spanning 150 million years. The method reached up to 93% agreement with expert identifications and aims to reduce subjectivity in matching tracks to specific dinosaur groups. The team released their code and an app called DinoTracker.

This black hole ate a star — and it’s still belching a brighter jet years later

A supermassive black hole 665 million light-years away is blasting an unusually persistent, bright radio jet years after shredding a red dwarf star, astronomers reported Thursday. The jet, monitored by telescopes in New Mexico and South Africa, continues to intensify and may peak in late 2026 or 2027. Researchers say the delayed, powerful outburst defies typical patterns seen after such stellar disruptions.

Robot Dog Climbs Mount Etna to Sniff Volcanic Gases — Here’s What It Found

ETH Zurich researchers sent a four-legged robot equipped with a mass spectrometer onto Mount Etna to autonomously sample volcanic gases in hazardous areas. The robot achieved up to 100% autonomy in some missions but struggled with wind and rough terrain, which scattered gas plumes and sometimes required manual control. The system detected sulfur dioxide, carbon dioxide, and five out of eight helium sources.

Methane spotted on interstellar comet 3I/ATLAS as new studies pin down its size

Scientists have directly detected methane in interstellar comet 3I/ATLAS, using data from the James Webb and Hubble telescopes collected in December. The comet’s nucleus is estimated at 2.6 km wide, larger than expected. Both findings are detailed in new arXiv preprints as the comet dims and leaves the inner solar system. Only three interstellar objects have been confirmed in the solar system to date.

NASA’s Artemis II Countdown Hits Critical Stage With Key Fueling Rehearsal Set for Monday

NASA began a full countdown and fueling rehearsal for Artemis II at Kennedy Space Center on Monday, loading super-cold propellants into the moon rocket despite freezing temperatures. The test, required before setting a crewed launch date, simulates a launch day without ignition. Any issues could push the first crewed Artemis mission past its February 8–11 window. Four astronauts are slated to fly around the Moon.

Hong Kong scientists say this AI can spot storms 4 hours early — why forecasters are watching

Hong Kong scientists say their new AI-based DDMS system can predict thunderstorms and heavy rain up to four hours in advance, extending warning times. The model updates every 15 minutes and improved forecast accuracy by over 15% in tests. China’s Meteorological Administration and the Hong Kong Observatory plan to integrate the system into official forecasts.

Northern Lights Tonight? NOAA says aurora could reach New York as solar storm lingers

NOAA extended geomagnetic storm warnings Wednesday after a rapid coronal mass ejection triggered by an X-class solar flare caused severe conditions. Auroras may be visible as far south as Alabama and northern California, with rare sightings in northern Italy and the UK. The storm reached G4 and S4 levels, threatening satellites, navigation, and polar flights. Forecasters say such intensity hasn’t been seen in over 20 years.

Northern Lights Could Reach Farther South Tonight After NOAA Flags Severe Solar Storm

Severe G4 geomagnetic storm levels were recorded early Tuesday after a coronal mass ejection struck Earth, NOAA said. A rare severe solar radiation storm was also underway, raising risks for polar flights and satellites. Agencies in the U.K. and Australia reported similar conditions and warned of possible G5 intervals. NOAA notified airlines, NASA, and grid operators as the situation developed.

Comet 3I/ATLAS suddenly looks “fully active” — and astronomers say the window is closing

NASA’s SPHEREx telescope recorded a surge in gas and dust from interstellar comet 3I/ATLAS after its close solar approach. The comet, only the third confirmed interstellar object in the solar system, will reach opposition on Jan. 22, offering extended nighttime viewing. Researchers detected water and carbon monoxide emissions about 20 times higher than earlier readings. 3I/ATLAS is already leaving the solar system.

ISS-grown bacteria-killing viruses return to Earth and hit E. coli harder, study finds

Bacteriophages evolved aboard the International Space Station became more effective at killing certain UTI-causing E. coli strains once returned to Earth, researchers at the University of Wisconsin-Madison reported. Microgravity delayed early infections and led to unique mutations in both the viruses and bacteria. Scientists say scaling up such space-based experiments remains difficult.
