Phys.org / Quantum algorithm beats classical tools on complement sampling tasks
Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers have worked to rigorously ...
Phys.org / Ant queen frozen in time: New ant species found in Dominican amber
A study by Dr. Gianpiero Fiorentino and his colleagues, published in the Journal of Paleontology, describes the identification of a new species of ant, Hypoponera electrocacica, belonging to the genus Hypoponera and representing ...
Medical Xpress / Shoulder scans in most people above 40 show rotator cuff abnormalities, pain or not
Shoulder pain is the third most common musculoskeletal complaint seen by doctors, affecting approximately 18–31% of the global population each month. Up to 85% of these cases are due to problems with the rotator cuff (RC)—the ...
Phys.org / Why laws named after tragedies win public support
When lawmakers name bills after victims of tragedy—such as Megan's Law or the Brady Handgun Violence Prevention Act of 1993—public support surges, but this emotional boost may come at the expense of sound policymaking, ...
Phys.org / Earth's mantle may have been cooler than thought before Pangea's breakup
When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the familiar geography of today ...
Phys.org / Missing geomagnetic reversals: Earth's past may be incomplete
Several studies have predicted that not all geomagnetic reversals have been discovered, but it was unknown in which periods they might be hidden. Researchers led by the National Institute of Polar Research used a statistical ...
Phys.org / Ultra-efficient optical sensors can keep light circulating longer inside a microscopic chip
CU Boulder researchers have built high-performing optical microresonators, opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and build up its intensity. ...
Phys.org / How the echolocation of bats has shaped their skulls
Bats are some of the most highly specialized mammals to have ever evolved. This includes not only the evolution of active flight, but also their echolocation. This ability requires the bats to produce high frequency noises ...
Phys.org / AI imaginary friends no substitute for human connection
Loneliness and social isolation are now recognized as major public health threats, prompting governments to explore technological solutions. Research from Monash University argues new AI "digital companions" marketed as a ...
Phys.org / Evidence links polyploidy and senescence in bladder cells, with implications for cancer
UConn Center on Aging researchers have published a new editorial in the journal Aging titled "Polyploidy-induced senescence: Linking development, differentiation, repair, and (possibly) cancer?" In this editorial, Dr. Iman ...
Phys.org / Large dogs release two to four times more airborne microbes than humans
Unseen but all around us, the air we breathe in enclosed spaces is crucial to our health and well-being. Indoor air is not simply outdoor air that has been run through a filter: it has its own chemical makeup and a unique ...
Phys.org / The optical engineering required to photograph an Earth twin
More and more papers are coming out about the upcoming Habitable Worlds Observatory (HWO). As the telescope moves from theory to practice (and physical manifestation), various working groups are discovering, defining, and ...
