Scientists have achieved something that once sounded almost impossible: using ordinary sunlight to create quantum-linked photon pairs, a phenomenon normally dependent on precise laboratory lasers. By building a sun-tracking system that funnels sunlight through optical fiber
Coffee may give your blood pressure a temporary jolt, but that doesn’t mean it’s secretly wrecking your heart. Researchers say caffeine can briefly raise blood pressure by stimulating your heart and tightening blood vessels, especially in people who don’t drink coffee
Scientists have uncovered evidence that the vanished Tethys Ocean may have sculpted Central Asia’s mountainous landscape during the dinosaur era. Using decades of geological data, researchers found that distant tectonic activity linked to the ancient ocean appears to match
Water is largely tasteless to humans. But to the microbial world, it is anything but. Bacteria that live in contaminated environments have spent millions of years evolving exquisitely sensitive molecular detectors—proteins that latch onto specific chemical threats and trigger a
Imagine a laptop that never gets hot, a phone that holds its charge for days, or a computer memory chip designed to permanently retain data, even when the power goes out. This is the possibility sitting inside a remarkable family of materials that a team of researchers from the
When it comes to space debris, what goes up is coming down more often—and not safely.
Most Americans know what a real expert's credentials look like: relevant degree, years of experience, and respect from peers. The problem, according to a study recently published in Scientific Reports, is that none of it matters as much once we find out their politics.
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor of 17 within just 18 months before recovering again.
Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been
The 1974 novel "Zen and the Art of Motorcycle Maintenance" offered a simple but enduring idea: Working on machines should not be about just fixing them, but slowing down, paying attention, and reflecting on both the work and oneself in the pursuit of quality.
Artificial intelligence (AI) systems, particularly conversational agents such as ChatGPT or Gemini, are now used daily by a growing number of people worldwide. While many users trust the answers of AI agents to their queries, these are not always accurate and reliable.
Hundreds of companies raised a combined $70 billion by selling shares to the public in the United States last year.
A joint European-Chinese spacecraft is set to blast off Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth's magnetic shield.
Every four years, the men's World Cup delivers some certainties. The pitch dimensions are tightly regulated, offside is signaled with a flag, and referees end the match with a blast of a whistle. But one key piece of equipment is changed on purpose: the ball.
A new nanoscopy technique developed at The Australian National University (ANU) has uncovered hidden networks used for communication between cells, opening new ways to understand human diseases. Described in an article published in Nature Communications, the method allows
Studies suggest watermelon could be a hidden powerhouse for better health. Researchers found that people who eat watermelon tend to have higher-quality diets packed with more vitamins, fiber, and antioxidants — while consuming less added sugar and saturated fat. Another study
Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or "flavors": a phenomenon known as neutrino oscillation that remains
Scientists have discovered that the human body undergoes a dramatic internal transformation during extended fasting, with major changes appearing only after about three days without food. In a seven-day water-only fasting study, researchers tracked thousands of proteins in the
The top predator prowling the seas during the age of the dinosaurs 100 million years ago may have been the octopus.
Genetic analysis suggests interbreeding between two groups of human relatives
The long-tailed pygmy rice rat is the primary host for Andes virus, the type of hantavirus responsible for sickening passengers on the MV Hondius cruise ship
A new nanotechnology treatment reversed Alzheimer’s symptoms in mice by restoring the brain’s natural cleanup system. The specially engineered nanoparticles helped clear toxic amyloid proteins from the brain and repair the blood-brain barrier, which normally protects and
A newfound nocturnal navigation system challenges what entomologists thought they knew about how ants find their way
A spectacular dinosaur discovery in Spain is giving scientists a rare new look inside the world of stegosaurs. Paleontologists uncovered the best-preserved stegosaur skull ever found in Europe, belonging to the iconic plated dinosaur Dacentrurus armatus, which roamed Earth
A long-lost manuscript discovered in Rome has revealed one of the oldest surviving versions of the very first known poem written in English. Hidden for decades and once believed lost, the 1,200-year-old manuscript contains Caedmon’s Hymn — a nine-line Old English poem said to
For years, “yo-yo dieting” has been blamed for wrecking metabolism and causing lasting damage, but a major new review says the fear may be wildly overblown. After analyzing decades of studies in humans and animals, researchers found little convincing evidence that losing weight
