Phys.org / Extending the lifespan of electrocatalysts via continuous chromium dissolution
Although chromium itself is not an active element, its continuous dissolution enables a reversible surface transformation that keeps the Co-Cr spinel oxide electrocatalyst active and stable. This could significantly improve ...
Phys.org / Humans are evolved for nature, not cities, say anthropologists
A new paper by evolutionary anthropologists Colin Shaw (University of Zurich) and Daniel Longman (Loughborough University) argues that modern life has outpaced human evolution. The study suggests that chronic stress and many ...
Phys.org / How most of the universe's visible mass is generated: Experiments explore emergence of hadron mass
Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, nature's fundamental building blocks bound together by gluons, their masses are much larger than the ...
Phys.org / Ape ancestors and Neanderthals likely kissed, new analysis finds
A new study led by the University of Oxford has found evidence that kissing evolved in the common ancestor of humans and other large apes around 21 million years ago, and that Neanderthals likely engaged in kissing too. The ...
Phys.org / Looking inside a well-preserved Neanderthal nose to solve a mystery about our ancestors' faces
A long-standing debate in paleontology about whether the distinctive Neanderthal nose evolved purely for the cold weather may have finally been solved, and it's all thanks to an ancient, exceptionally preserved nasal cavity.
Phys.org / Video catches wild wolf pulling in crab trap to get to food—but is it tool use?
Many animals have been observed using tools. For example, chimps tear leaves off of branches and stick them into holes to pull out termites, and wild dingoes have been observed moving objects to stand on to get to another ...
Phys.org / Why mysterious structures within Earth's mantle hold clues to life here
For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.
Phys.org / Deep imaging suggests isolated galaxy forms stars without signs of past mergers
Using the Two-meter Twin Telescope (TTT3), Spanish astronomers have conducted deep optical imaging of an isolated dwarf galaxy known as NGC 6789. Results of the new observations, presented November 10 on the arXiv preprint ...
Phys.org / New synthesis strategy for (–)-gukulenin A reveals the chemistry behind its anticancer effects
A team of researchers from Yale University, U.S., successfully achieved the first stereoselective synthesis of the complex natural product (–)-gukulenin A (7), which exhibits notable cytotoxicity against ovarian cancer.
Phys.org / Quantum teleportation between photons from two distant light sources achieved
Everyday life on the internet is insecure. Hackers can break into bank accounts or steal digital identities. Driven by AI, attacks are becoming increasingly sophisticated. Quantum cryptography promises more effective protection. ...
Phys.org / Archaeologists reveal second-largest Roman olive oil mill in the Roman Empire
Ca' Foscari University of Venice is co-directing a major international archaeological mission in the Kasserine region of Tunisia. The excavations, focused on the area of ancient Roman Cillium, on the border with present-day ...
Phys.org / Disputed Jordan codices reveal age variations under ion-beam scrutiny
Scientists have delivered the most detailed assessment yet of a set of disputed lead books known as the Jordan codices. With debate centered on whether they could date back to the early Christian period, a study led by the ...
