Phys.org / New research turns the Dunning-Kruger effect on its head: Rethinking the confident incompetent
Researchers at the University of Bath and The London School of Economics and Political Science (LSE) suggest that the celebrated Dunning-Kruger effect, often taken to mean the least competent people are the most overconfident, ...
Phys.org / New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.
Phys.org / Physicists capture first direct evidence of a Floquet topological state
A new study published in Nature Physics reports the first direct experimental evidence of a Floquet topological state, a novel light-induced phase of matter that, until now, has existed only on paper and in simulations. Topological ...
Dialog / Near a black hole, gravity changes a quantum circuit's readings, not its rules
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...
Phys.org / 'I can't work in the farce of climate change cruise tourism anymore': Why Antarctic guides quit their dream jobs
In the words of a former Antarctic tour guide we interviewed: "You'd see massive glacier calvings, and you'd just want to cry. But all the guests would be cheering. And you'd be like … 'can you not put two and two together?'"
Phys.org / Pennsylvania roads are being coated in radioactive wastewater—here's why
Pennsylvania's roughly 100,000 oil and gas wells produce wastewater that's many times saltier than seawater and contains radium, a known carcinogen. For decades, that saltwater, called brine, was spread on dirt and gravel ...
Phys.org / A way to read quantum bits faster and with less hardware
Quantum computers process information in a fundamentally different way from conventional computers, using quantum bits, or qubits, that can exist in multiple states at once. This could allow them to tackle problems beyond ...
Phys.org / Chicxulub's lingering dust may have turned falling debris into a global firestorm
Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico's Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that ...
Phys.org / Psychologist develops puzzle that can tell you how fast you think
A puzzle that can tell players how fast they think on their feet has been developed by a University of Leeds researcher.
Phys.org / More evidence Mars once had water emerges from old Spirit rover data
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
Medical Xpress / Scientists decipher how T cells sense enemies—such as cancer—at point of contact
Every encounter between a T cell and a potential target—especially when that target is a developing tumor—begins with a rapid series of molecular decisions. Within seconds, the immune cell must determine whether to launch ...
Phys.org / Prolonged stretching reorganizes tissue scaffolds and uncages cell nuclei
How do tissues cope with being stretched for hours or even days? A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC) has uncovered an unexpected answer: Cells radically reorganize their internal ...
