Phys.org / Levitated nano-ferromagnet confirms a 160-year-old physical prediction
Ferromagnets, such as iron, cobalt, and nickel, are materials with a strong, spontaneous, and permanent magnetic field. Over 150 years ago, the physicist and mathematician James Clerk Maxwell speculated that under specific ...
Phys.org / NASA connects little red dots with Chandra and Webb
A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A "X-ray dot" found by NASA's Chandra X-ray Observatory ...
Phys.org / Roman cup unearthed in Spain may have been a keepsake representing a soldier's time at the Hadrian Wall
Archaeologists recently analyzed a broken, decorative cup found unexpectedly on a Spanish farm. The cup appears to represent Hadrian's Wall—a place 2,000 miles away—and a time period almost 2,000 years ago. The new study, ...
Phys.org / The 'tail' of the shrinking dog brain: Study reveals they began getting smaller 5,000 years ago
Dogs have long been known to have smaller brains than the wolves they descended from. But when they started to shrink has been a matter of some debate. New research published in the journal Royal Society Open Science, which ...
Phys.org / Newly confirmed supernova remnant is one of the faintest ever detected
An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery ...
Phys.org / New copy of earliest poem in English language discovered by researchers in Rome
An early ninth-century manuscript containing a text of the first known poem in the English language has been discovered in Rome by researchers from Trinity College Dublin. The newly-discovered manuscript in the National Central ...
Phys.org / Frozen in dry ice, hydrogen reveals a surprisingly simple way to control quantum behavior
A new study by University of Maryland chemical physicists demonstrates how to control the nuclear spin of molecular hydrogen (H2) by simply freezing it in dry ice. This new technique, published in the journal Physical Review ...
Phys.org / The most common planets in the galaxy don't appear around the most common stars, TESS observations suggest
Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from McMaster University reveals ...
Phys.org / After Rome: Genomic insights from southern Germany reveal the formation of Central European societies
Many of today's villages and towns in Central Europe trace their origins to settlements that emerged after the collapse of the Western Roman Empire, often on former Roman territory or in the immediate vicinity of the Limes, ...
Phys.org / Atomic-column imaging uncovers hidden magnetic structures in antiferromagnets
Antiferromagnetic materials, with antiparallel atomic spins and zero net magnetization, are fast and resistant to external magnetic interference, making them ideal for high-speed, high-density spintronic devices. However, ...
Phys.org / Nanofiltration for cleaner water is stopping one of farming's most persistent chemicals from slipping through
Water is fundamental to all life—contaminants are harmful to humans and the environment. Herbicides used in agriculture to control weeds present a particular challenge here. The most widely used herbicide in the world is ...
Phys.org / Online game uncovers why tiger stripes work best in sunshine and tall grass
Scientists have used an online game to discover the secrets of animal camouflage—such as why tigers have stripes. The study, by the universities of Exeter and Bristol, reveals that high-contrast markings like tiger stripes ...
