Researchers at EPFL have developed a chip-scale ultrafast laser that performs on par with traditional tabletop femtosecond lasers. The innovation could make advanced laser technologies far smaller, cheaper, and more accessible for applications ...

A large study of older adults in Brazil found that adding extra salt at the table is still a common habit, especially among men. While too much salt is linked to serious health problems and faster cognitive decline, researchers discovered that women ...

For decades, pancreatic cancer has been one of the most lethal cancers, with few effective treatment options. A new drug, daraxonrasib, targets the KRAS mutation that fuels most pancreatic tumors--something many scientists once thought couldn't be .. ...

Scientists examining amber from Goethe's personal collection discovered three hidden fossil insects, including an extinct ant preserved in extraordinary detail. Advanced 3D imaging allowed researchers to see not only the ant's outer features but also ...

A newly discovered genetic clock acts as the master timekeeper for development, orchestrating crucial bursts of gene activity throughout a worm's growth. When the clock is disrupted, development stops, offering fresh clues about how growth-related .. ...

Hidden beneath Arctic waters, beluga whales have long kept their family lives a mystery. By analyzing DNA from more than 600 belugas in Alaska's Bristol Bay over 13 years, researchers uncovered a surprisingly flexible mating system: both males and .. ...

Researchers have discovered how microscopic imperfections and atomic vibrations can be used to control a powerful quantum effect in an advanced material. The effect can turn alternating electrical signals from the environment directly into the kind . ...

Scientists have uncovered a surprising new way the immune system fights cancer, overturning a core belief that has guided immunology for decades. The research found that when cancer cells shut down a key immune-recognition molecule called MHC I--a .. ...

NASA's James Webb Space Telescope has uncovered unusual chemistry in interstellar comet 3I/ATLAS, including the first direct detection of methane on a visitor from another star system. The comet also contains exceptionally high levels of carbon ...

June's night sky delivers several must-see events, starting with a close encounter between Venus and Jupiter after sunset. Mercury joins the pair to form a rare three-planet lineup, while the Moon puts on a special show by passing in front of Venus . ...
