Phys.org / Webb sheds more light on composition of planetary debris around nearby white dwarf
Using the James Webb Space Telescope (JWST), astronomers have performed infrared observations of a planetary debris disk around a nearby white dwarf known as GD 362. Results of the new observations, presented October 8 on ...

Phys.org / Hidden for centuries: Archaeologists unearth ancient Roman water basin
In the heart of the ancient Roman city of Gabii, located just 11 miles east of Rome, a team of archaeologists led by University of Missouri professor Marcello Mogetta has made a remarkable discovery: the remains of a massive ...

Phys.org / Quantum mechanics trumps the second law of thermodynamics at the atomic scale
Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked (so-called correlated ...

Phys.org / New family of fluorescent molecules glows in water, enhancing visualization of cells
A team of researchers at the Departments of Physical Chemistry and Organic Chemistry of the University of Malaga and The Biomimetic Dendrimers and Photonic Laboratory of the research institute IBIMA Plataforma BIONAND has ...

Phys.org / Bats' brains reveal a global neural compass that doesn't depend on the moon and stars
Some 40 kilometers east of the Tanzanian coast in East Africa lies Latham Island, a rocky, utterly isolated and uninhabited piece of land about the size of seven soccer fields. It was on this unlikely patch of ground that ...

Phys.org / Triplets born from proton collisions found to be correlated with each other
For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy collisions in the LHC accelerator, it has been possible to observe their coherent production. This achievement ...

Phys.org / Why Classic Maya cities rose and fell
Why move to a city? And why leave? Urban centers today see populations ebb and flow for a multitude of reasons—the economy, crowds, lifestyle considerations, air quality, the odd pandemic perhaps. As it turns out, it's ...

Phys.org / 50-year mystery of ancient 'subway deer' discovered in Canada is solved
In 1976, during the excavation of a subway extension in Toronto, a city worker discovered unusual looking antlers with "thick, horizontal beams."

Phys.org / Surprising bacteria discovery links Hawaiʻi's groundwater to the ocean
A new species of bacteria has been discovered off the coast of Oʻahu, shedding light on how unseen microbial life connects Hawaiʻi's land and sea ecosystems.

Phys.org / Two green comets shine bright. How to spot them in the night sky
Two bright green comets are streaming through the skies and are visible to skygazers in the Northern Hemisphere.

Phys.org / Old-school material could power quantum computing and cut data center energy use
A new twist on a classic material could advance quantum computing and make modern data centers more energy efficient, according to a team led by researchers at Penn State.

Phys.org / Time crystals could power future quantum computers
A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel Laureate in Physics, proposed quantum systems––like groups of particles––could construct themselves ...
