This tiny power module could change how the world uses energy

13:43
As global energy demand surges—driven by AI-hungry data centers, advanced manufacturing, and electrified transportation—researchers at the National Renewable Energy Laboratory have unveiled a breakthrough that could help squeeze far more power from existing electricity supplies. Their new silicon-carbide-based power module, called ULIS, packs dramatically more power into a smaller, lighter, and c…

How the frog meat trade helped spread a deadly fungus worldwide

13:43
A deadly fungus that has wiped out hundreds of amphibian species worldwide may have started its global journey in Brazil. Genetic evidence and trade data suggest the fungus hitchhiked across the world via international frog meat markets. The findings raise urgent concerns about how wildlife trade can spread hidden biological threats.

Scientists trace fertilizer microplastics from fields to beaches

13:43
Plastic-coated fertilizers used on farms are emerging as a major but hidden source of ocean microplastics. A new study found that only a tiny fraction reaches beaches through rivers, while direct drainage from fields to the sea sends far more plastic back onto shore. Once there, waves and tides briefly trap the particles on beaches before many vanish again. This helps explain why so much plastic …

New research shows emotional expressions work differently in autism

13:43
Researchers found that autistic and non-autistic people move their faces differently when expressing emotions like anger, happiness, and sadness. Autistic participants tended to rely on different facial features and produced more varied expressions, which can look unfamiliar to non-autistic observers. The study suggests emotional misunderstandings are a two-way street, not a one-sided deficit.

Cannabis was touted for nerve pain. The evidence falls short

13:43
Cannabis-based medicines have been widely promoted as a potential answer for people living with chronic nerve pain—but a major new review finds the evidence just isn’t there yet. After analyzing more than 20 clinical trials involving over 2,100 adults, researchers found no strong proof that cannabis products outperform placebos in relieving neuropathic pain. Even when small improvements were repo…

How cancer disrupts the brain and triggers anxiety and insomnia

13:43
Scientists have discovered that breast cancer can quietly throw the brain’s internal clock off balance—almost immediately after cancer begins. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the brain-body feedback loop that regulates stress, sleep, and immunity. Remarkably, when researchers restored the correct day-night rhythm in specific brain neurons, stress …

Silver just solved a major solid-state battery problem

5:09
Solid-state batteries could store more energy and charge faster than today’s batteries, but they tend to crack and fail over time. Stanford researchers found that a nanoscale silver treatment can greatly strengthen the battery’s ceramic core. The silver helps seal tiny flaws and prevents lithium from causing further damage. This simple approach could help unlock next-generation batteries.

Scientists find ‘master regulator’ that could reverse brain aging

5:09
Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. The findings challenge long-held assumptions about tau’s necessity and highlight a promising new path for fighting Alzheimer’s and brain aging. Scientists now believe OTULIN may act as a master switch f…

The real danger of Tylenol has nothing to do with autism

18:32
While social media continues to circulate claims linking acetaminophen to autism in children, medical experts say those fears distract from a far more serious and proven danger: overdose. Acetaminophen, found in Tylenol and many cold and flu remedies, is one of the leading causes of emergency room visits, hospitalizations, and acute liver failure in the United States.

Scientists sent viruses to space and they evolved in surprising ways

18:32
When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both viruses and bacteria evolved differently over time. Genetic changes emerged that altered how viruses attach to bacteria and how bacteria defend themselves. The findings could help improve phage therapies…

The Ring Nebula is hiding a giant structure made of iron

18:32
A huge bar of iron has been discovered lurking inside the iconic Ring Nebula. The structure is enormous, spanning hundreds of times the size of Pluto’s orbit and containing a Mars-sized amount of iron. It was detected using a new instrument that allowed astronomers to map the nebula in far greater detail than ever before. The origin of the iron bar is still a mystery, with one theory suggesting i…

A once-in-a-generation discovery is transforming dairy farming

18.ledna
A Michigan dairy farm took a gamble on a new kind of soybean—and it paid off fast. After feeding high-oleic soybeans to their cows, milk quality improved within days and feed costs dropped dramatically. Backed by years of MSU research, the crop is helping farmers replace expensive supplements with something they can grow themselves. Demand has surged, and many believe it could reshape the dairy i…

A 47-year study reveals when fitness and strength start to fade

18.ledna
A long-running Swedish study has followed adults for nearly five decades, uncovering when physical decline truly begins. Fitness and strength start slipping around age 35, then worsen gradually with age. The encouraging twist: adults who began exercising later still improved their physical capacity by up to 10 percent. It’s a powerful reminder that staying active matters, even if you start late.

Microplastics are undermining the ocean’s power to absorb carbon

18.ledna
Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth’s most powerful climate defenses. New research suggests microplastics are disrupting marine life that helps oceans absorb carbon dioxide, while also releasing greenhouse gases as they break down. By interfering with plankton, microbes, and natural carbon cycles, these pollutants reduce the ocean’s ability to …

Tiny earthquakes are revealing a dangerous secret beneath California

17.ledna
Scientists are uncovering a hidden and surprisingly complex earthquake zone beneath Northern California by tracking swarms of tiny earthquakes that are far too weak to feel. These faint tremors are revealing what lies beneath the surface where the San Andreas fault meets the Cascadia subduction zone, one of the most dangerous seismic regions in North America.
