Phys.org / Electron and photon beams drive same gold-forming reaction toward different nanoscale structures
Beauty and mystery—it is hard to imagine a more alluring combination, and this is precisely what we encounter when we observe phenomena in the nanoworld. But are we really sure that observations made using modern microscopic ...
Phys.org / Microfluidic device simulates human tissue and offers an alternative to animal testing
Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have developed microfluidic technology that can grow cells in three dimensions (3D). The goal is to conduct toxicity tests on new products by ...
Phys.org / Urban fire risk rises 30% in higher-income neighborhoods, analysis finds
Frequently located on hillsides and in canyons surrounded by wildlands, wealthy neighborhoods are more likely to catch fire. However, a UC Riverside study shows they are also likely to recover faster than lower-income areas.
Phys.org / How some cyclists paradoxically start 'from rest' with a non-zero velocity
Some track cyclists appear to break the rules of physics, but a new study, published in the journal Royal Society Open Science, has created a model explaining the illusion. The results suggest that a quick succession of well-timed ...
Phys.org / Iron Age seeds reveal the origins of Iberian wine
Spain and Portugal are two of the world's most popular wine-growing countries, with regions such as Rioja and the Douro Valley producing millions of bottles every year. This winemaking tradition dates back thousands of years, ...
Phys.org / Mathematician challenges a 2,000-year-old legend about the Parthenon's optical illusions
One of Athens' crowning jewels is the Parthenon, a classical temple on the Acropolis that overlooks the Greek capital. According to legend, many historians, textbooks and tour guides say the ancient Greek architects who designed ...
Phys.org / Tyrannosaurus rex teeth reveal a body temperature close to the human average
When picturing a scaled, toothy Tyrannosaurus rex stomping across North America, building nests and eating other dinosaurs, it's easy to forget that scientists have gleaned everything we know about T. rex from clues left ...
Phys.org / Webb measures extreme gas outflows from distant 'dead' galaxies
Astronomers using the James Webb Space Telescope have measured the most powerful gas outflow ever recorded from a "dead" galaxy outside our cosmic neighborhood and found that even outflows this extreme may not be enough to ...
Phys.org / Tendon cells can rebound from stiffness when returned to softer tissue-like surroundings
Researchers at Queen Mary University of London are closer to understanding tendinopathy, a common condition that can cause persistent pain and impaired movement in people and many animals.
Phys.org / Caffeine pollution could disrupt crustacean defenses against predators
While most people are aware of how plastic, arsenic and various industrial chemicals can pollute bodies of water, the effects of caffeine on freshwater environments remain largely unknown. Nonetheless, traces of caffeine, ...
Phys.org / Weeping whales: Stillborn humpback whale grieving documented
Humpback whale mothers may experience grief when their calves die, a rare research observation led by Griffith University and Sea World Foundation has found.
Phys.org / We may soon be able to read long-lost ancient scrolls damaged by the eruption of Mount Vesuvius
X-ray technology and artificial intelligence—along with the discovery of lead in the ink of fragments from a collection of ancient Roman scrolls—could soon help scientists read long-lost texts buried by the eruption of Mount ...
