Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that help tumors grow, adapt, and survive treatment. By tracking thousands of individual cells over time, the approach shows which chromosome combinations give cancer an edge and why some tumors become especially resilient.View the full article

Alzheimer’s may destroy memory by flipping a single molecular switch that tells neurons to prune their own connections. Researchers found that both amyloid beta and inflammation converge on the same receptor, triggering synapse loss. Surprisingly, neurons aren’t passive victims—they actively respond to these signals. Targeting this receptor could offer a new way to protect memory beyond current amyloid-focused drugs.View the full article

A newly uncovered immune chain reaction in the gut may explain why people with inflammatory bowel disease face a much higher risk of colorectal cancer. Researchers found that a powerful inflammatory signal flips on specialized gut immune cells, which then call in waves of white blood cells from the bone marrow and rewire them in ways that help tumors grow. This process appears to damage DNA in the gut lining and create a tumor-friendly environment.View the full article

A Roman-era skeleton discovered in southern England has finally given up her secrets after more than a decade of debate. Known as the Beachy Head Woman, she was once thought to have roots in sub-Saharan Africa or the Mediterranean—an idea that sparked global attention. But new, high-quality DNA analysis paints a different picture: she was most likely a local woman from Roman Britain.View the full article

A massive new study comparing more than 100,000 people with today’s most advanced AI systems delivers a surprising result: generative AI can now beat the average human on certain creativity tests. Models like GPT-4 showed strong performance on tasks designed to measure original thinking and idea generation, sometimes outperforming typical human responses. But there’s a clear ceiling. The most creative humans — especially the top 10% — still leave AI well behind, particularly on richer creative work like poetry and storytelling.View the full article

Long before farming took hold, ancient Indigenous peoples of the American Southwest were already shaping the future of a wild potato. New evidence shows that this small, hardy plant was deliberately carried across the Four Corners region more than 10,000 years ago, helping it spread far beyond its natural range.View the full article

Researchers have developed a technique that allows them to carve complex three dimensional nanodevices directly from single crystals. To demonstrate its power, they sculpted microscopic helices from a magnetic material and found that the structures behave like switchable diodes. Electric current prefers one direction, but the effect can be flipped by changing the magnetization or the twist of the helix. The findings show that geometry itself can be used as a tool for electronic design.View the full article

After analyzing 40 years of tree records across the Andes and Amazon, researchers found that climate change is reshaping tropical forests in uneven ways. Some regions are steadily losing tree species, especially where conditions are hotter and drier, while others are seeing gains. Rainfall patterns turned out to be just as important as rising temperatures.View the full article

Scientists are warning that a little-known group of microbes called free-living amoebae may pose a growing global health threat. Found in soil and water, some species can survive extreme heat, chlorine, and even modern water systems—conditions that kill most germs. One infamous example, the “brain-eating amoeba,” can cause deadly infections after contaminated water enters the nose. Even more concerning, these amoebae can act as hiding places for dangerous bacteria and viruses, helping them evade disinfection and spread.View the full article

Researchers have found that a natural aging-related molecule can repair key memory processes affected by Alzheimer’s disease. The compound improves communication between brain cells and restores early memory abilities that typically fade first. Because it already exists in the body and declines with age, boosting it may offer a safer way to protect the brain. The discovery hints at a new strategy for slowing cognitive ageing before severe damage sets in.View the full article

NASA is moving into a new phase of space exploration, with major progress across human spaceflight, science missions, and advanced technology. In just one year, the agency has launched multiple crewed and science missions, test-flown new aircraft, and pushed forward plans for the Moon, Mars, and beyond. With Artemis II set to send astronauts around the Moon for the first time in more than 50 years, NASA is laying the groundwork not just for a return to the lunar surface, but for a sustained human presence in deep space.View the full article

Falling space junk is becoming a real-world hazard, and scientists have found a clever new way to track it using instruments already listening to the Earth itself. By tapping into networks of earthquake sensors, researchers can follow the sonic booms created when space debris tears through the atmosphere, revealing where it traveled, broke apart, and possibly hit the ground.View the full article

A distant Sun-like star suddenly went dark for months, stunning astronomers who quickly realized something massive was passing in front of it. Observations revealed a gigantic disk of gas and dust filled with vaporized metals, swirling around an unseen companion object. For the first time, scientists directly measured the motion of these metallic winds inside such a disk. The findings suggest that even ancient star systems can still experience catastrophic planetary smashups.View the full article

Chronic inflammation may be quietly reshaping the colon and making it more vulnerable to early-onset colorectal cancer. Scientists found that colon tissue in younger patients was stiffer, even in areas that appeared healthy, suggesting these changes may happen before cancer develops. Lab experiments showed that cancer cells grow faster in rigid environments.View the full article

Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more deadly in older adults. Turning off this signal reduced inflammation and improved survival in older models. The findings hint at future treatments that could dial back harmful immune overreactions.View the full article

People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to spinal stimulators. The system can detect when a patient is trying to move, though finer control remains a challenge. Scientists hope future improvements could turn intention into action.View the full article

Locust swarms can wipe out crops across entire regions, threatening food supplies and livelihoods. Now, scientists working with farmers in Senegal have shown that improving soil health can dramatically reduce locust damage. By enriching soil with nitrogen, crops become less appealing to the insects, leading to fewer locusts, less plant damage, and harvests that doubled in size.View the full article

A large, decades-long study suggests that signs of ADHD in childhood may have consequences that extend well beyond school and behavior. Researchers followed nearly 11,000 people from childhood into midlife and found that those with strong ADHD traits at age 10 were more likely to experience multiple physical health problems and health-related disability by their mid-40s.View the full article

Scientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide’s atoms are arranged at extremely high temperatures, researchers discovered a specific form that can rival platinum in key chemical reactions, including turning carbon dioxide into useful fuels and chemicals. Even more promising, the same material proved dramatically better at breaking down plastic waste, outperforming platinum by more than tenfold.View the full article

A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering both star-forming regions and the remains of ancient stellar explosions. Scientists can now better distinguish where stars are being born versus where they’ve met dramatic ends. The discovery opens powerful new ways to study the life cycle of stars and the shape of our galaxy.View the full article

Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring matter far faster than theory says it should—about 13 times the usual “speed limit”—while simultaneously blasting out bright X-rays and launching a powerful radio jet. This surprising combination wasn’t supposed to happen, according to many models, and suggests scientists may be catching the black hole during a brief, unstable growth spurt.View the full article

Pancreatic cancer may evade the immune system using a clever molecular trick. Researchers found that the cancer-driving protein MYC also suppresses immune alarm signals, allowing tumors to grow unnoticed. When this immune-shielding ability was disabled in animal models, tumors rapidly collapsed. The findings point to a new way to expose cancer to the body’s own defenses without harming healthy cells.View the full article

Giant kangaroos that lived during the Ice Age may not have been as slow and grounded as once believed. A new study finds their leg bones and tendons were likely strong enough to support hopping, despite their massive size. Rather than traveling this way all the time, these animals may have relied on short bursts of hopping. This ability could have played a key role in escaping predators.View the full article

Chemotherapy’s gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels to the bone marrow. This signal reshapes immune cell production, strengthening anti-cancer defenses and making metastatic sites harder for tumors to colonize. Patient data suggest this immune rewiring is linked to better survival.View the full article

Alzheimer’s may be driven far more by genetics than previously thought, with one gene playing an outsized role. Researchers found that up to nine in ten cases could be linked to the APOE gene — even including a common version once considered neutral. The discovery reshapes how scientists think about risk and prevention. It also highlights a major opportunity for new treatments aimed at a single biological pathway.View the full article
