Phys.org / 'Heel-strike' may have allowed early humans to walk farther—at the cost of high-impact forces
The average person takes thousands of steps each day, instinctively walking heel-to-toe. Although they hardly register them, those consistent heel-first strides are more distinctive to humans than previously thought and allowed ...
Medical Xpress / Newly discovered stem cell reveals potential drug target for spinal stenosis
Researchers at Weill Cornell Medicine and Hospital for Special Surgery have discovered the unspecialized stem cells that give rise to the body's tendons and ligaments, the tissues connecting muscles and bones.
Phys.org / Some disagreement makes groups more trustworthy, mathematical framework finds
When humans are making decisions, they are known not to rely solely on their own considerations and the evidence available to them. Past behavioral science and psychology studies have shown that people are often also influenced ...
Phys.org / Weak hydrogen bonds dethrone copper as the most stable metal binder, opening a new path for metal selection
Copper has been knocked off the top of a stability ranking it had dominated for decades. Without altering the atoms directly bonded to the metal, a KAIST research team reversed the longstanding trend in which copper generally ...
Phys.org / Excavations at Prado Vargas now span 140 square meters of a Neanderthal layer
The 2026 field season at Prado Vargas Cave, located in the village of Cornejo in the northern province of Burgos, Spain, within the Ojo Guareña karst complex, has expanded the excavation of Neanderthal sublevel 4D by 32 square ...
Phys.org / Inexpensive blue pigment enables efficient one-step conversion of carbon dioxide to methane
A common blue pigment could help turn carbon dioxide (CO₂) from an industrial waste product into a useful fuel. A joint research team led by Tohoku University's Advanced Institute for Materials Research (WPI-AIMR), in collaboration ...
Medical Xpress / Disabling a gene brake in pancreatic cells unlocks insulin-producing potential
Type 1 and 2 diabetes are ultimately caused by a shortage of beta (β) cells, which are present in the pancreas and produce insulin to control blood sugar. Researchers from Harvard Medical School found that they can tweak ...
Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning
Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...
Medical Xpress / How the heart, lungs and brain work together to shape experience
People speak of "butterflies in the stomach," a "racing heart," being "choked up" or needing to "catch breath." Language routinely treats emotion and thought as though they inhabit the body. But why are events of the mind ...
Phys.org / Hawai'i high school students name image of glittering galaxy pair
Nā ʻUhane Māhoe Huki Pū i ke Ola is the Hawaiian name given to NGC 7253—a pair of spiral galaxies caught in each other's gravity. Captured by the Gemini North telescope on Maunakea in Hawai'i, the image created a spectacular ...
Medical Xpress / Self-control matures later than working memory in adolescence, large analysis finds
Adolescence, the developmental phase between childhood and adulthood, is marked by substantial mental, emotional and social changes. Past psychological studies suggest that during this stage, humans gradually acquire greater ...
Tech Xplore / Climate, not concrete mix, may drive steel corrosion in low-carbon structures
It is hard to imagine the modern world without concrete. Enormous quantities are used in construction worldwide, and the production of cement—its main ingredient—generates a great deal of CO₂, a greenhouse gas that accelerates ...
