Scientists find a way to break pancreatic cancer’s protective shield
Researchers found that blocking IL1RAP could disrupt a powerful inflammatory network that helps pancreatic cancer survive treatment. In preclinical experiments, the approach reduced tumor-protecting cells …
Mercury’s surface reveals a surprisingly fiery past
Scientists have discovered that Mercury’s surface contains far less silicon dioxide than previously thought, pointing to an unexpectedly hot volcanic past. The finding suggests ancient …
The secret to longer life may be hidden in bat DNA
Long-lived bats appear to combine powerful immune defenses with unusual strategies for eliminating damaged cells, potentially helping them avoid cancer and disease for decades. Researchers …
66-million-year-old feather in dinosaur poop may reveal why birds survived the asteroid
A feather discovered inside 66-million-year-old fossilized dinosaur poop may help explain why modern birds survived the asteroid catastrophe. The extinct bird it came from had …
Your next prescription could be treating a side effect from the last …
A major Ontario study found 24 common medication chains in which one drug’s side effects can be mistaken for a new medical problem, leading to …
Tiny nanolaser could cut computer energy use in half
Scientists have created an ultra-small nanolaser that could eventually allow microchips to transmit information with light instead of electricity, potentially making computers faster while cutting …
Scientists just made quantum computer operations 1,000 times faster
Researchers have found a way to perform certain quantum operations more than 1,000 times faster, cutting thousands of repeated control cycles down to just one. …
Wasps are disappearing this summer, and scientists are worried
Britain’s wasps have become mysteriously scarce this summer, and scientists suspect an unusual combination of temperature swings, heatwaves, and food shortages may be responsible. Even …
Study of 1.9 million people finds a striking link between ADHD and …
Researchers analyzing data from more than 1.9 million people found that ADHD is associated with substantially higher rates of digestive problems. People with ADHD had …
Physicists just found a tiny glitch in time itself
Unconventional quantum theories may imply that time itself has a tiny fundamental uncertainty, placing an ultimate limit on how precisely any clock could measure it. …
Too much light at night may quietly reshape your heart
Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. …
Scientists find signs of extreme aging and youth in the same 117-year-old
A remarkably detailed study of Maria Branyas, who lived past 117, reveals that extreme longevity may involve both intense aging and powerful biological protection at …
Scientists discover the human heart can regrow muscle after a heart attack
Researchers have shown for the first time that human heart muscle cells can regrow after a heart attack. The finding overturns the idea that damaged …
Eating only 8 hours a day may help control Type 1 diabetes
Eating only between noon and 8 p.m. improved blood sugar control in a small study of adults with Type 1 diabetes and obesity, while avoiding …
UCLA scientists turn cord blood into powerful cancer-fighting T cells
UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a …
DNA solves the mystery of a body found in the Arctic in …
Scientists have used DNA from living descendants to identify four more members of the doomed Franklin expedition, including Harry Peglar, whose identity had remained uncertain …
Scientists create brilliant white material without a drop of white pigment
Researchers have created a foam-based material that produces intense whiteness and water repellency without titanium dioxide pigments or PFAS chemicals. Inspired by natural structures in …
Archaeologists find a 3,000-year-old Egyptian tomb before it’s too late
While clearing debris to protect ancient Egyptian tombs from flash floods, researchers near Luxor stumbled upon an unknown 3,000-year-old tomb. Its remarkably preserved paintings depict …
