Researchers using new simulations suggest that the Milky Way’s past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long thought to come from pulsars. The findings revive dark matter as a major suspect in one of astronomy’s biggest mysteries and set the stage for crucial future observations.

With NASA's Mars Sample Return mission delayed into the 2030s, engineers are certifying the Perseverance rover to keep operating for many more years while it continues collecting and safeguarding Martian rock samples. Ars Technica reports: The good news is that the robot, about the size of a small SUV, is in excellent health, according to Steve Lee, Perseverance's deputy project manager at NASA's Jet Propulsion Laboratory (JPL). "Perseverance is approaching... Read more ›

An anonymous reader quotes a report from the Financial Post: A Texas power developer is proposing to repurpose nuclear reactors from Navy warships to power the United States grid as the Trump administration pushes to secure massive amounts of energy for the artificial intelligence boom. HGP Intelligent Energy LLC filed an application to the Energy Department to redirect two retired reactors to a data center project proposed at Oak Ridge,... Read more ›

A reported attempt by a covert Chinese lab to reverse-engineer an EUV lithography scanner underscores that, despite access to scattered components, replicating ASML's EUV tools is effectively impossible without recreating the company's entire global supply chain, optics ecosystem, and proprietary software built over decades.

The Justice Department justified its delayed release of sensitive files by citing the need to carefully redact information that could identify victims, but at least some of those redactions have proven to be technically ineffective and can be bypassed by simply copying and pasting the blacked-out text into a new document. A 2022 complaint filed by the US Virgin Islands seeking damages from Jeffrey Epstein's estate appeared on the DOJ's... Read more ›

A major international review has upended long-held ideas about how top performers are made. By analyzing nearly 35,000 elite achievers across science, music, chess, and sports, researchers found that early stars rarely become adult superstars. Most world-class performers developed slowly and explored multiple fields before specializing. The message is clear: talent grows through variety, not narrow focus. Read more ›

A new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equations are missing or too complicated to write down. Read more ›

New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could reshape how Alzheimer’s is prevented and treated. Read more ›

For years, scientists thought Saturn’s moon Titan hid a global ocean beneath its frozen surface. A new look at Cassini data now suggests something very different: a thick, slushy interior with pockets of liquid water rather than an open sea. A subtle delay in how Titan deforms under Saturn’s gravity revealed this stickier structure. These slushy environments could still be promising places to search for life. Read more ›

A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed better metabolism, stronger muscles, and healthier fat tissue. Their cells produced more energy while dialing down oxidative stress and inflammation tied to aging. The results hint that improving cellular power output could help slow the aging process itself.

Researchers have revealed that so-called “junk DNA” contains powerful switches that help control brain cells linked to Alzheimer’s disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that truly influence gene activity—many tied to known Alzheimer’s risk genes. The findings help explain why many disease-linked genetic changes sit outside genes themselves. The resulting dataset is now being used to train AI systems to predict... Read more ›

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found predators operating at a food-chain level higher than any seen today. The ancient seas were bursting with life, from giant reptiles to rich invertebrate communities. This extreme complexity reveals how intense competition helped drive the evolution of modern marine ecosystems. Read more ›

Researchers have found that fossilized dinosaur eggshells contain a natural clock that can reveal when dinosaurs lived. The technique delivers surprisingly precise ages and could revolutionize how fossil sites around the world are dated. Read more ›

Balanophora is a plant that abandoned photosynthesis long ago and now lives entirely as a parasite on tree roots, hidden in dark forest undergrowth. Scientists surveying rare populations across East Asian islands uncovered how its cellular machinery shrank but didn’t disappear, revealing unexpected similarities to parasites like malaria. Some island species even reproduce without sex, cloning themselves to colonize new habitats. This strange survival strategy comes with risks, leaving the... Read more ›
