1441. AI searched 100 million possibilities and found a cheaper way to 3D-print a NASA rocket alloy

Researchers used AI to search through more than 100 million possible settings for 3D-printing a high-performance NASA alloy. After only 40 experiments, the system identified six successful configurations, including one that worked at a record-low 500 watts. That could allow GRCop-42, currently difficult and expensive to print, to be made with much more widely available equipment.

1442. “I jumped from my chair” – Astronomers spot Betelgeuse’s hidden companion

Astronomers have captured their clearest image yet of Betelgeuse’s long-suspected companion, potentially ending a search that lasted about 100 years. The surprisingly massive hidden star could help explain Betelgeuse’s changing brightness and may influence its future supernova.

1443. Scientists discover a brain “brake” that can shut down chronic pain

Researchers discovered a brain-based “brake” that can shut down chronic nerve pain in mice by calming an overactive pain circuit. Targeting this system more precisely could one day lead to powerful pain relief without affecting opioid receptors throughout the entire body.

1444. Scientists may have finally caught “empty” space changing light

A magnetar with an astonishingly powerful magnetic field may have revealed a quantum effect predicted by Werner Heisenberg nearly 90 years ago. Its light shows signs that supposedly empty space is altering how the light travels, potentially providing the first evidence of vacuum birefringence.

1445. NASA just used satellites and debris to navigate without GPS

NASA has successfully tested a system that allows satellites to navigate without GPS by using other spacecraft and debris as landmarks in orbit. In just three days, FALCON also improved the known orbits of more than 200 space objects completely autonomously.

1446. Scientists switch on a strange new form of magnetism in an ultrathin material

Scientists have found a surprising way to potentially switch on an unusual form of magnetism in ruthenium dioxide, a material that normally appears nonmagnetic. When the material was made into an ultrathin film only a few atomic layers thick and placed under strain, its electrons developed patterns consistent with altermagnetism, a recently proposed magnetic state with promising uses in advanced electronics.

1447. Eating more ultra-processed foods may raise prostate cancer risk by 30%

Ultra-processed foods make up a huge share of the American diet, and new research suggests they may carry another serious health risk for men. In a nationally representative study of more than 17,000 U.S. men, those who ate more ultra-processed foods, including soft drinks, packaged snacks, cereals, and processed meats, had roughly 24% to 31% higher risks of prostate cancer after accounting for factors such as age, smoking, race and ethnicity, and poverty status.

1448. Smart nanoparticles light up brain cancer and destroy what surgery misses

Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurrence and led to 100% survival at 60 days, though it has not yet been tested in humans.

1449. A mysterious cosmic hum may come from 13-billion-year-old dark stars

Today’s mysterious gravitational-wave background may preserve clues about how the Universe’s first supermassive black holes formed. Descendants of hypothetical Dark Stars could be responsible for a major portion of the signal, offering a surprising new way to investigate cosmic dawn and dark matter.

1450. 324-million-year-old fossil reveals how insects conquered land

Ancient fossils suggest insects conquered land through a long amphibious phase rather than making an abrupt jump from water to dry ground. A newly identified 324-million-year-old species still carried paddle-like abdominal limbs, revealing an evolutionary bridge between aquatic ancestors and modern six-legged insects.

1451. Vitamin C won’t prevent most colds, but it may do one small thing

The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not prevent most people from catching a cold, although regularly taking it may make severe symptoms slightly shorter or milder.

1452. Your dislike of eating bugs may be 9,000 years old

Ancient teeth and human DNA are revealing a surprising history of insect eating. Modern humans in northern Eurasia appear to have eaten insects only occasionally, while Neanderthals may have consumed them much more regularly. Populations near the tropics also retained genes that make insect exoskeletons easier to digest.
