Phys.org / How sound and light act alike—and not—at the smallest scale
A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the emerging field of quantum ...
Phys.org / Oldest oceanic reptile ecosystem from the Age of Dinosaurs found on Arctic island
More than 30,000 teeth, bones and other fossils from a 249 million-year-old community of extinct marine reptiles, amphibians, bony fish and sharks have been discovered on the remote Arctic island of Spitsbergen. These record ...
Phys.org / Mystery of how much squid short-finned pilot whales eat resolved
How much squid do short-finned pilot whales (Globicephala macrorhynchus) off the coast of Hawai'i need to consume each day to survive and are there sufficient squid to sustain the population? Knowing these basic facts is ...
Phys.org / Hitler's DNA reveals possible genetic disorder tied to sexual and social behavior
Adolf Hitler most likely suffered from the genetic condition Kallmann Syndrome that can manifest itself in undescended testicles and a micropenis, researchers and documentary makers said Thursday, following DNA testing of ...
Phys.org / Scientists uncover surprising link between koala and Ice Age 'marsupial lion'
A sleepy koala may seem worlds apart from a giant Ice Age predator, but scientists have uncovered the first molecular evidence linking the two.
Phys.org / How fishes of the deep sea have evolved into different shapes
Fish species living in the deep sea feature a surprisingly large range of body shapes that evolved in different ways and at different rates depending on where the fishes live in the ocean, new research shows.
Phys.org / Machine learning teaches membranes to sort by chemical affinity
Ultrafiltration membranes used in pharmaceutical manufacturing and other industrial processes have long relied on separating molecules by size. Now, Cornell researchers have created porous materials that filter molecules ...
Phys.org / Physicists unveil system to solve long-standing barrier to new generation of supercomputers
The dream of creating game-changing quantum computers—supermachines that encode information in single atoms rather than conventional bits—has been hampered by the formidable challenge known as quantum error correction.
Phys.org / Putting less meat and more legumes in school menus reduces environmental impact by up to 50%
The transition to healthy diets with a low environmental impact is crucial to achieving sustainable food systems and reducing health problems. In this context, dietary guidelines for schools can encourage eating behaviors ...
Phys.org / Algorithms reveal how propane becomes propylene for everyday products
Countless everyday products, from plastic squeeze bottles to outdoor furniture, are derived by first turning propane into propylene.
Phys.org / Wild birds are driving the current US bird flu outbreak
Since late 2021, a panzootic, or "a pandemic in animals," of highly pathogenic bird flu variant H5N1 has devastated wild birds, agriculture, and mammals. Unlike previous outbreaks, aggressive culling of domestic birds has ...
Phys.org / Heavy atomic nuclei are not as symmetric as previously thought, physicists find
Many heavy atomic nuclei are shaped more or less like squashed rugby balls than fully inflated ones, according to a theoretical study by RIKEN nuclear physicists published in The European Physical Journal A. This unexpected ...
