A promising fatty liver treatment may raise cancer risk

10:56
A surprising new study reveals that blocking a supposedly protective enzyme, Caspase-2, could actually backfire—raising the risk of chronic liver damage and cancer over time. Researchers found that without this enzyme, liver cells grow abnormally large and accumulate genetic damage, leading to inflammation, scarring, and eventually tumors, especially with age. While inhibiting Caspase-2 may offer…

New blood test could catch pancreatic cancer before it’s too late

10:56
A new blood test could change the outlook for one of the deadliest cancers—pancreatic cancer—by catching it much earlier than ever before. Researchers identified two previously unknown proteins in the blood that, when combined with existing markers, dramatically improved detection accuracy. The four-marker test was able to spot pancreatic cancer in over 90% of cases and performed especially well …

Microplastics are falling from the sky and polluting forests

10:56
Tiny plastic particles aren’t just choking oceans and cities—they’re quietly infiltrating forests too. Scientists discovered that most microplastics arrive through the air, settling onto treetops before being washed or dropped to the forest floor in rain and falling leaves. Once there, natural processes like leaf decay help bury and store these particles deep in the soil. The findings reveal fore…

Most people get food’s environmental impact completely wrong, study finds

10:56
People often get the environmental impact of food wrong, according to new research. While many assume processed foods are the worst, they tend to overlook the surprisingly high impact of items like nuts and underestimate how damaging beef really is. These misunderstandings come from relying on simple categories like “animal vs. plant” rather than the full picture.

Scientists discover Alzheimer’s hidden “death switch” in the brain

10:56
Scientists have uncovered a hidden “death switch” in the brain that may be driving Alzheimer’s disease—and even found a way to turn it off in mice. The culprit is a toxic pairing of two proteins that, when combined, triggers the destruction of brain cells and fuels memory loss. By using a new compound to break apart this deadly duo, researchers were able to slow disease progression, protect brain…

Scientists discover surprising brain trigger behind high blood pressure

4:53
Scientists have uncovered a surprising brain-based trigger for high blood pressure, tracing it to a small region in the brainstem that normally controls breathing. This area, which kicks in during forceful exhalations like coughing, laughing, or exercise, also appears to activate nerves that tighten blood vessels—raising blood pressure. When researchers switched off this region in experiments, bl…

Scientists twisted a mysterious superconductor and got a shocking result

4:53
A decades-old superconducting mystery just took a surprising turn. Strontium ruthenate, a material that conducts electricity with zero resistance at low temperatures, has long puzzled scientists with hints of an exotic, complex superconducting state. But by carefully twisting and distorting ultra-thin crystals, researchers found something unexpected: the material barely reacted at all. This chall…

World’s first quantum battery could enable ultra fast charging

4:53
Scientists in Australia have demonstrated a prototype quantum battery that could revolutionize energy storage. By harnessing quantum effects, it can absorb energy in a rapid “super absorption” event, enabling much faster charging than conventional batteries. Even more surprisingly, the system becomes more efficient as it scales up. The research opens the door to ultra-fast, next-generation energy…

This floating time crystal breaks Newton’s third law of motion

3:15
Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles interact in a one-sided, unbalanced way, breaking the usual rules of motion and creating a steady, repeating rhythm. The system is surprisingly simple yet reveals complex physics with big implications. It could help advance quantum computing and deepen our understanding of biolo…

Weight loss drug Ozempic cuts depression, anxiety, and addiction risk

22.března
GLP-1 medications like semaglutide (Ozempic) may offer unexpected mental health benefits alongside weight loss. A large study found major drops in depression, anxiety, and psychiatric-related hospital visits among users. Even substance use disorders were significantly lower during treatment. Researchers suspect both lifestyle improvements and direct brain effects could be at play.

Why mosquitoes always find you and how they decide to attack

22.března
Scientists have finally cracked how mosquitoes decide where to fly—and it’s not by following each other. Instead, each insect independently reacts to visual cues and carbon dioxide, zeroing in on humans when both signals align. Dark colors and CO2 together create the strongest attraction, triggering swarming and biting behavior. This insight could reshape how we design traps and prevent mosquito-…

Beavers are turning rivers into powerful carbon sinks

22.března
Beavers may be unlikely climate heroes, but new research suggests they could play a powerful role in fighting climate change. By building dams and transforming streams into wetlands, these industrious animals dramatically reshape how carbon moves and is stored in landscapes. Over just 13 years, a beaver-engineered wetland in Switzerland stored over a thousand tonnes of carbon—up to ten times more…

This 67,800-year-old handprint is the oldest art ever found

22.března
Researchers have uncovered the world’s oldest known cave art—a 67,800-year-old hand stencil in Indonesia. The unusual, claw-like design hints at early symbolic thinking and possibly spiritual beliefs. This discovery also strengthens the case that humans reached Australia at least 65,000 years ago. It offers rare insight into the creative lives of some of our earliest ancestors.

Webb Telescope spots “impossible” atmosphere on ancient super Earth

22.března
Astronomers have uncovered surprising evidence of a thick atmosphere surrounding TOI-561 b, a scorching, fast-orbiting rocky planet once thought too extreme to hold onto any gas. Using NASA’s James Webb Space Telescope, researchers found the planet is far cooler than expected for a bare rock, hinting at a heat-distributing atmosphere above a churning magma ocean. This strange world—where a year l…

Friction without contact discovered as magnetic forces break a 300-year-old law

22.března
Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that dramatically increase resistance at certain distances. This creates a surprising peak in friction instead of a steady rise, breaking a long-standing physics law.
