Massive study of 460,000 people challenges ultra-processed food cancer fears
A massive study of more than 460,000 Americans found that ultra-processed foods were not associated with increased colorectal cancer risk overall, challenging a widely held assumption. While processed meat was linked to higher cancer incidence, ultra-p…
Too much RNA can starve cells of energy, scientists discover
Scientists have uncovered an unexpected danger lurking inside cells: too much RNA can damage the structures responsible for producing energy. A new study found that excess RNA, including the normally essential messenger RNA (mRNA), can directly disrupt…
A train was delayed by a solar storm. But something didn’t add up.
Scientists have cracked a 178-year-old mystery surrounding a train delayed by a solar storm, revealing that the famous incident happened in 1848 rather than 1841. The discovery rewrites the early history of space weather and highlights a threat that st…
Astronauts’ hearts just passed a surprising test for Mars
A new study tracking 13 astronauts suggests that the human heart may be surprisingly well equipped for a journey to Mars, especially with regular exercise during spaceflight. Researchers found that astronauts’ hearts adapted to months of weightlessness…
Rejuvenation breakthrough: Scientists reverse 60 years of aging in human cells
Scientists have turned blood cells from an 80-year-old into neural stem cells with a molecular age of less than 20, effectively reversing more than 60 years of cellular aging in the laboratory. The discovery offers a new way to investigate how cells be…
Just 4 minutes a day can dramatically improve strength after 65
A new Penn State study suggests that just four minutes of daily strength training can significantly improve mobility and physical function in older adults. After 12 weeks, participants showed meaningful gains in balance, leg strength, and their ability…
NASA’s Perseverance Mars rover just shattered the all-time off-world driving record
NASA’s Perseverance rover has shattered a historic space exploration record, traveling farther across another world than any vehicle before it. Its advanced self-driving system helped it surpass Opportunity’s 28.06-mile record in just five and a half y…
A massive asteroid slammed into the North Sea and unleashed a 330-foot tsunami
A decades-long mystery beneath the North Sea has finally been solved. Scientists have confirmed that the Silverpit Crater, buried 700 meters below the seabed, was created when a 160-meter-wide asteroid struck Earth roughly 43 to 46 million years ago. T…
Scientists discover ghostly, eyeless creature hidden in Chinese cave
Deep inside a high-altitude Chinese cave, scientists discovered a ghostly, eyeless freshwater snail that has evolved to live entirely in darkness, marking the first recorded discovery of its kind in China. Named after a faceless mythical creature, the …
