Phys.org / Distant time crystals oscillate in unison, paving the way for spin networks
In January 2024, physicists at TU Dortmund University demonstrated a continuous time crystal in a semiconductor whose oscillations remained stable for hours. In a new study published in Nature Communications, Professor Alex ...
Medical Xpress / Testing finds 85% of everyday personal care products contain unlabeled chemicals with suspected health hazards
A new study of sunscreens, baby lotions, shampoos, soaps and other everyday products found that nearly all contained chemicals not disclosed on their labels. Most contained at least one unlabeled chemical with known or suspected ...
Phys.org / Crocodiles can't fly. Birds can. Scientists have finally figured out why
The closest living relatives of crocodiles and alligators are, perhaps surprisingly, birds. Both are archosauriforms, a group of species that originated about 250 million years ago near the beginning of the Triassic period.
Phys.org / Bringing butterflies back from the brink of extinction
On a summer day in Michigan, a tiny Poweshiek skipperling butterfly—smaller than a quarter—takes flight over a restored prairie.
Phys.org / 20-year study finds pre-K impacts a child's academic future
Students who attended public school pre-K performed better academically through high school than those in family-based child care, according to new research from Florida International University.
Phys.org / AI-assisted grant proposals may win more often—while narrowing research ideas
A new study from Northwestern's Kellogg School of Management found that research proposals showing stronger signs of AI-assisted writing were four percentage points more likely to receive funding from the National Institutes ...
Phys.org / When it comes to predicting people's preferences, it pays to consider 'the power of three'
In his 1927 paper, "A law of comparative judgment," the American psychologist L. L. Thurstone proposed that when people select one option among multiple alternatives, they are picking the one that has the highest value to ...
Phys.org / Californians are twice as likely as Louisianans to be childfree—but demographics tell more of the story
Across the United States, the number of people who do not have and do not want to have children is growing. While they are twice as likely to live in California as Louisiana, individual demographic characteristics are the ...
Phys.org / Three energy-loss routes may explain Tarantula Nebula's X-ray shortfall
Like a collage made of layered sheets of colored cellophane, a vibrant new image layers observations of a famous star-forming nebula from NASA's space telescopes. The resulting cosmic "craft" reveals new details about the ...
Medical Xpress / Cortical organoids mirror mouse brain cell types, yet lose developmental sequence
Over a decade ago, scientists redefined how to study organ development by generating seemingly unremarkable clumps of cells. They dubbed them organoids: organ-like microstructures produced using stem cells. Stem cells are ...
Tech Xplore / 'Forgetful' AI semiconductor processes recent inputs without separate resets
For the first time, researchers have demonstrated that the "ability to forget" can serve as a new computational function for artificial intelligence.
Phys.org / Arctic cyclone clusters batter sea ice, leaving coasts more exposed to storms
In the Arctic, weather plays a key role in determining how much ice covers the ocean. Arctic cyclones are one weather phenomenon with a significant influence, causing unusually warm and stormy conditions that typically lead ...
