This town found clean energy deep inside old coal mines

5:09
Cumberland, B.C. is reimagining its coal mining past as a clean energy opportunity. Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions. The project could lower energy costs, support new development, and attract businesses. It’s a striking example of turning industrial leftovers into a sustainable community…

Scientists finally solve 40-year-old physics puzzle about how things grow

5:09
In a major breakthrough, scientists have experimentally confirmed a universal growth law in two dimensions using a quantum system of fleeting light–matter particles. The finding strengthens the idea that wildly different processes—from crystals to living systems—may all follow the same hidden rules.

Scientists reverse diabetes in mice with lab-grown insulin cells

5:09
Scientists in Sweden have taken a major step toward a potential cure for type 1 diabetes by developing a more reliable way to create insulin-producing cells from human stem cells. These lab-grown cells not only respond strongly to glucose but were also able to restore blood sugar control when transplanted into diabetic mice.

NASA captures wild swirling clouds and rare arctic storm over Alaska

5:09
Southern Alaska’s winter finale delivered a spectacular atmospheric display, captured by a NASA satellite. Cold Arctic air flowing over warmer ocean waters created long bands of clouds, swirling vortex patterns, and even a compact polar storm with powerful winds. As the air traveled offshore, it evolved into increasingly complex cloud formations. The result was a dramatic, ever-changing sky that …

NASA just tested a powerful new thruster that could send humans to Mars

5:09
A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory. Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space. Glowing hotter than molten lava and firing inside a specialized vacuum chamber, the th…

Blue Origin’s new moon lander just survived extreme space testing on Earth

5:08
A bold step toward returning humans to the Moon is underway with Blue Origin’s uncrewed MK1 “Endurance” lander, designed to test the technologies that future astronauts will rely on. Built in partnership with NASA, the mission will showcase precision landing, autonomous navigation, and advanced cryogenic propulsion—key capabilities for operating on the lunar surface. It will also carry cutting-ed…

MIT scientists discover millions of “silent synapses” in the adult brain

5:08
MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of “silent synapses,” dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these inactive links make up about 30% of synapses in the adult cortex and can be rapidly activated to form fresh memories.

New AI method tackles one of science’s hardest math problems

10:26
Penn researchers have developed a smarter AI method for solving notoriously difficult inverse equations, which help scientists uncover hidden causes behind observable effects. By introducing “mollifier layers” that smooth noisy data, they’ve made these calculations more stable and far less computationally demanding. This could transform fields like genetics, where understanding how DNA behaves is…

Colon cancer breakthrough keeps patients cancer-free for nearly 3 years

9:22
A short burst of immunotherapy before surgery is delivering surprisingly powerful results for a specific type of colorectal cancer. Patients in a UK-led trial who received just nine weeks of pembrolizumab prior to surgery have remained cancer-free nearly three years later—an outcome that challenges the standard approach of surgery followed by months of chemotherapy.

Common knee surgery found ineffective, may make things worse

9:22
A major 10-year clinical trial is turning one of the world’s most common knee surgeries on its head. Researchers found that trimming a damaged meniscus—a procedure long believed to relieve pain—offers no real benefit over placebo surgery. Even more surprising, patients who had the operation actually fared worse over time, with more symptoms, poorer function, faster progression of osteoarthritis, …

240-million-year-old giant “sand creeper” found hidden in retaining wall

9:22
A forgotten fossil hidden inside a garden wall has turned out to be one of Australia’s most remarkable prehistoric discoveries. Scientists have now identified the 240-million-year-old amphibian, Arenaerpeton supinatus, revealing an almost perfectly preserved skeleton—complete with rare traces of skin. This ancient river predator, about 1.2 meters long, looked somewhat like a giant salamander but …

This common sleep habit could double your risk of heart attack

6.května
A chaotic sleep schedule in your 40s might be quietly setting the stage for heart trouble later. Researchers tracking thousands of people for over a decade found that those with highly inconsistent bedtimes—especially when they slept less than eight hours—faced about double the risk of serious cardiovascular events like heart attacks or strokes. Interestingly, it wasn’t when people woke up that m…

Oak trees are delaying spring to starve caterpillars

6.května
Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait. When trees are heavily attacked one year, they delay leaf growth by just three days the next spring—long enough to leave newly hatched caterpillars with nothing to eat. This small shift slashes insect survival and reduces leaf damage by more than half, proving even more efficient than costly chemical de…

Webb space telescope reveals a scorching “super-Earth” that looks like Mercury

6.května
A scorching, airless world just 48 light-years away is offering scientists a rare glimpse into the geology of distant planets. Using the James Webb Space Telescope, researchers studied LHS 3844 b—a tidally locked “super-Earth” with a permanent dayside hot enough to melt metal—and discovered it’s a dark, barren rock with no atmosphere.

Scientists boost strawberry flavor and nutrition without changing growth

6.května
A surprising genetic twist shows that boosting a seemingly ordinary “housekeeping” gene can dramatically improve fruit quality without any trade-offs. By increasing the activity of a tRNA-related gene in strawberries, researchers unlocked richer color, stronger aroma, and higher levels of health-boosting compounds like anthocyanins and terpenoids. Even more striking, these enhancements came with …
