Phys.org / Switching spin states in manganese ions with light opens new path for molecular memory

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular ...

Phys.org / New cellular model for rare and deadly melanomas enables study of immunotherapy resistance

A research team at the University of Turku in Finland has developed a reliable laboratory model to study BAP1-deficient melanomas, which are a rare type of melanoma that evade the immune system once they have metastasized ...

Phys.org / UV light patterns thermochromic crystals without damage, unlocking color-changing designs

Color-changing mood rings, forehead fever strips and car-shade indicators all change hues as they warm and cool, thanks to a phenomenon called thermochromism. On a smaller scale, thermochromism is used in nanotechnologies ...

Phys.org / Deep-sea extremophile yields protein that forms super stable biofilm

Scientists discovered a protein secreted by a deep-sea extremophile—an organism adapted to extreme environmental conditions—that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.

Phys.org / Tiny DNA 'hitchhikers' may be reshaping life in thawing Arctic soils

Amid the peatlands of northern Sweden, billions of microbes are quietly rewriting their genetic playbooks—and doing so far more often than scientists realized.

Phys.org / Urban growth may slow by 2100, leaving big cities smaller than expected

The world is urbanizing fast. In 1975, about 11% of the global population lived in cities with more than 1 million inhabitants. "Today, we estimate that share to be about 24%," says Andrea Musso, junior fellow at the Complexity ...

Phys.org / Cyclic sealing and drainage on the Gofar Oceanic Transform Fault revealed

Oceanic transform faults are strike-slip boundaries—faults that move horizontally rather than up and down and connect offset mid-ocean ridge segments. They have long been regarded as simple "conservative" plate boundaries ...

Phys.org / This tiny organism contracts 200 times faster than we can blink—here's how

A tiny, aquatic, single-celled organism can contract to one-quarter of its body length in less than 5 milliseconds—hundreds of times faster than a human can blink. Researchers have discovered that the organism, Spirostomum ...
