Cancer uses antioxidants to disarm the immune system, scientists discover

Free radicals have traditionally been associated with damage to the body’s cells, leading to widespread interest in whether antioxidants might help prevent cancer. But new research suggests these often misunderstood molecules also play an important role in protecting us from the disease. Scientists have discovered that certain immune cells actually…

Comets may have destroyed life's ingredients instead of delivering them to Earth

For nearly a century, scientists have considered the possibility that comets helped make life on Earth possible by delivering essential organic molecules from space. Now, new research suggests this long-standing explanation is extremely unlikely. Comets are known to contain many of the chemical compounds associated with the origins of life.…

Global carbon dioxide emissions from fossil fuels are expected to decline slightly in 2026, offering a promising sign that the world’s transition to cleaner energy is beginning to make a measurable difference. According to the latest Global Carbon Budget from the Global Carbon Project, fossil fuel CO2 emissions are projected…

NASA offers $500,000 to develop next-generation electric rocket engines

NASA is offering $500,000 in prizes to encourage American companies to develop more capable electric propulsion systems for future space missions. The competition focuses on a technology known as Hall effect thrusters, which use electricity to propel spacecraft through space. The new initiative, called the Advanced Mid-Power Electric Rocket (AMPERE)…

Why heart attacks can still happen even when bad cholesterol is low

Researchers at Chalmers University of Technology in Sweden have uncovered new clues about why some people develop heart disease even after lowering their bad cholesterol to recommended levels. Their findings point to biological processes involving other fat-carrying particles in the blood that may contribute to cardiovascular damage in ways that…

Alzheimer’s may have early warning signs outside the brain

Alzheimer’s disease is best known for its effects on memory and thinking, but new research suggests that some symptoms may develop in a surprising place: outside the brain. Scientists at the University of Central Florida (UCF) have discovered that genetic mutations associated with Alzheimer’s can interfere with the nerves that…

After 40 years, CERN finds evidence of a one-in-10-billion particle decay

After more than 40 years of searching, physicists at CERN have reached a major milestone in their hunt for one of the rarest known particle decays. Researchers working with the LHCb experiment have detected evidence of a process expected to occur only once in approximately 10 billion beauty particle decays.…

Scientists finally discover why we learn to love bitter coffee

A first taste of black coffee can be surprisingly unpleasant. Its sharp bitterness is the kind of flavor our brains are naturally inclined to avoid. Yet millions of people eventually come to enjoy that same taste, often looking forward to their morning cup. What changes? Scientists at UC San Francisco…

Common supplement could help fight psoriasis, scientists discover

A widely available nutritional supplement derived from vitamin B5 may offer a promising new approach to treating psoriasis, according to research from China. Scientists found that pantethine can calm immune cells involved in autoimmune inflammation, preventing psoriasis from developing in mice and improving symptoms in a small human clinical trial.…

When your gut bacteria run out of fiber, they may start eating your gut lining

Eating more plants is widely associated with better health, but scientists are still uncovering exactly why. New research suggests that fiber is only part of the story. Certain plant proteins that resist digestion may also play a surprisingly important role in shaping gut bacteria and determining whether they produce beneficial…

A quantum breakthrough makes light behave like both a solid and a liquid

Scientists have demonstrated an extraordinary form of quantum matter that combines two properties that seem incompatible. Known as a supersolid, this unusual state has the orderly structure of a crystal while also displaying the frictionless flow associated with a special kind of liquid. Even more remarkably, researchers have now observed…

Scientists discover a surprising link between acorns and lyme disease

Tick-borne illnesses are becoming increasingly common across the United States, and Lyme disease remains the most frequently reported. Nearly 500,000 Americans are diagnosed each year. The infection is caused by the bacterium Borrelia burgdorferi, which typically reaches humans through the bite of an infected blacklegged tick. Antibiotics can treat Lyme…

A simple supplement may help clear brain fog after cancer

For some breast cancer survivors, the effects of treatment can linger long after their cancer care ends. Memory lapses, difficulty concentrating, and persistent exhaustion can interfere with everyday life, sometimes for years. Now, researchers at the UCLA Health Jonsson Comprehensive Cancer Center have found promising early evidence that a supplement…

Caltech robot makes history by building a structure in space

For the first time, a robot has successfully assembled part of a structure in space without astronauts, demonstrating a technology that could dramatically change how large spacecraft and scientific instruments are built. The robotic system was developed by researchers at the California Institute of Technology (Caltech) with funding from the…
