This ultra-sensitive imaging system can spot cancer earlier15:35 A new imaging technology can distinguish cancerous tissue from healthy cells by detecting ultra-weak light signals. It relies on nanoparticles that bind to tumor markers, making cancerous areas easier to identify. The system is far more sensitive than existing tools and could speed up cancer screening. Scientists believe it may help detect tumors earlier and reduce delays in diagnosis. Scientists find a weak spot in deadly fungus that shut down hospital intensive care units15:35 A deadly hospital fungus that resists nearly every antifungal drug may have an unexpected weakness. Researchers discovered that Candida auris activates specific genes during infection to hunt for nutrients it needs to survive. This insight came from a new living-host model that allowed scientists to watch the fungus in action. The findings could eventually lead to new treatments or allow current … This fish-inspired filter removes over 99% of microplastics15:35 Washing machines release massive amounts of microplastics into the environment, mostly from worn clothing fibers. Researchers at the University of Bonn have developed a new, fish-inspired filter that removes over 99% of these particles without clogging. The design mimics the funnel-shaped gill system used by filter-feeding fish, allowing fibers to roll away instead of blocking the filter. The low… Dinosaur bones found almost on top of each other in Transylvania15:35 Scientists exploring Romania’s Hațeg Basin have discovered one of the densest dinosaur fossil sites ever found, with bones lying almost on top of each other. The K2 site preserves thousands of remains from a prehistoric flood-fed lake that acted like a natural bone trap 72 million years ago. Alongside common local dinosaurs, researchers uncovered the first well-preserved titanosaur skeletons ever… MIT scientists strip cancer of its sugar shield15:35 Scientists at MIT and Stanford have unveiled a promising new way to help the immune system recognize and attack cancer cells more effectively. Their strategy targets a hidden “off switch” that tumors use to stay invisible to immune defenses—special sugar molecules on the cancer cell surface that suppress immune activity. Early tests show it can supercharge immune responses and outperform current … Hidden brain maps that make empathy feel physical15:35 When we watch someone move, get injured, or express emotion, our brain doesn’t just see it—it partially feels it. Researchers found eight body-like maps in the visual cortex that organize what we see in the same way the brain organizes touch. These maps help us instantly understand actions, emotions, and intentions in others. The discovery sheds light on human empathy and opens doors for new brai… Physicists made atoms behave like a quantum circuit15:35 Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of quantum computers and voltage standards. The appearance of Shapiro steps in this atomic system reveals a deep universality in quantum physics and makes elusive microscopic effects visible for the first time. Are they really listening? Watch their blinks15:35 Your eyes may reveal when your brain is working overtime. Researchers found that people blink less when trying to understand speech in noisy environments, especially during the most important moments. The effect stayed the same in bright or dark rooms, showing it’s driven by mental effort, not light. Blinking, it turns out, is a quiet marker of focused listening. This cancer-fighting molecule took 50 years to build22.prosince MIT scientists have achieved the first-ever lab synthesis of verticillin A, a complex fungal compound discovered in 1970. Its delicate structure stalled chemists for decades, despite differing from related molecules by only two atoms. With the synthesis finally complete, researchers created new variants that showed strong activity against a rare pediatric brain cancer. The breakthrough could unlo… Why evolution rewarded ants that sacrificed protection22.prosince Some ants thrive by choosing numbers over strength. Instead of heavily protecting each worker, they invest fewer resources in individual armor and produce far more ants. Larger colonies then compensate with collective behaviors like group defense and coordinated foraging. The strategy has been linked to evolutionary success and greater species diversity. A new drug could stop Alzheimer’s before memory loss begins22.prosince New research suggests Alzheimer’s may start far earlier than previously thought, driven by a hidden toxic protein in the brain. Scientists found that an experimental drug, NU-9, blocks this early damage in mice and reduces inflammation linked to disease progression. The treatment was given before symptoms appeared, targeting the disease at its earliest stage. Researchers say this approach could r… Why one long walk may be better than many short ones22.prosince How you walk may matter just as much as how much you walk. A large UK study tracking more than 33,000 low-activity adults found that people who grouped their daily steps into longer, uninterrupted walks had dramatically lower risks of early death and heart disease than those who moved in short, scattered bursts. This simulation reveals what really happens near black holes22.prosince Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and matter, researchers have built simulations that closely match real astronomical observations. These models reveal how matter forms chaotic, glowing disks and launches powerful outflows as it falls i… Subaru Telescope reveals a hidden giant planet22.prosince Astronomers have uncovered a massive hidden planet and a rare “failed star” by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope in Hawaiʻi, the OASIS survey tracked subtle stellar wobbles to pinpoint where unseen worlds were lurking—then captured them directly. This AI finds simple rules where humans see only chaos22.prosince A new AI developed at Duke University can uncover simple, readable rules behind extremely complex systems. It studies how systems evolve over time and reduces thousands of variables into compact equations that still capture real behavior. The method works across physics, engineering, climate science, and biology. Researchers say it could help scientists understand systems where traditional equati… |
