Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its grav…
Without this protein, damaged muscle turns to fat and scar tissue
A protein once thought to mainly protect chromosome ends may also be essential for keeping muscle stem cells ready to repair injuries. Researchers found that TRF2 helps these cells maintain their identity and coordinate the cycle of rest, repair, and r…
Mathematicians prove perfectly fair elections are impossible
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete. A newly proposed voting method could soften these unavoidable trade-o…
This once-a-week workout may help cut belly fat, study shows
A surprisingly small dose of exercise may deliver major health benefits for adults carrying excess fat around the waist. In a four-month trial involving 315 adults with central obesity, researchers found that completing 75 minutes of brisk interval wal…
Eating less protein could slow aging, major review finds
A sweeping review of more than 350 studies suggests that the protein boom may be overselling what many people actually need. Eating less protein appears to improve metabolism, reduce inflammation and cellular damage, and activate pathways linked to hea…
Cancer may be breaking its own DNA to keep growing
Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accum…
Mysterious Milky Way object accelerates protons beyond one quadrillion electron volts
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy.
NASA’s Curiosity rover finds a mysterious honeycomb landscape on Mars
NASA’s Curiosity rover has entered a Martian valley covered by an astonishing “sea” of tiny polygon-shaped fractures. The honeycomb patterns, each only a few inches wide, stretch across the landscape and even wrap around a nearby 20-foot-tall butte.
Tiny black holes may be secretly exploding stars across the Milky Way
Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars acros…
Scientists detect a sharp acceleration in global warming
Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with jus…
Ant brains reveal how evolution turned hunger into parenting
Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow…
Eating one avocado a day may lower heart disease risk
A daily avocado may help lower heart disease risk in adults with obesity by reducing the number of LDL particles circulating in the blood. After six months, participants who ate an avocado each day experienced a decline associated with an estimated 4% …
