Phys.org / Simple semiconductor films break light's front-back symmetry
Light typically interacts with a material the same way whether it enters through the front or the back—like polarized sunglasses that work the same from either side. Cornell researchers have demonstrated a simple route to ...
Phys.org / New quantum chip architecture could use built-in vibrations to link distant qubits
A new concept from Warwick researchers could help solve one of the biggest challenges to building large-scale quantum computers: enabling communication between vast numbers of quantum bits (qubits) over long distances across ...
Tech Xplore / Game-engine forests train drone AI to count trees with far less labeling
A drone swoops low over an alpine forest. It climbs suddenly to follow the contours of the sharply rising landscape. Pulses from its lidar—a laser mapping instrument—rapidly scan the trees below.
Medical Xpress / Study shows that social inequality exacerbates barriers to physical activity
A 10-year study of residents of São Paulo, Brazil, reveals that leisure-time physical activity is highly unequal and that the gap between social strata is widening. While highly educated white men are exercising more, women ...
Phys.org / Twisted laser light distinguishes mirror-image molecules by their fragment counts
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers ...
Phys.org / Scientists' biographies may demotivate, not inspire, children to study science
Currently popular biographies of famous scientists may demotivate—rather than inspire—children's desire to study or pursue careers in science, according to researchers who studied the messages in 422 bestselling children's ...
Phys.org / Gene discovery could shave years off avocado breeding
Scientists have found a genetic switch that could shave years off avocado breeding by allowing researchers to identify one of a young tree's most important traits long before it flowers.
Phys.org / Two antibody gene systems may help explain vesper bats' unusual viral tolerance
It is a mystery that has puzzled scientists for years. How can the world's only winged mammals carry viruses that cause severe disease while rarely becoming seriously ill themselves?
Medical Xpress / How brain cells restore healthy growth and connections after a disease-causing genetic deletion
Scientists at Virginia Tech's Fralin Biomedical Research Institute at VTC have discovered how an experimental therapy can help brain cells overcome the effects of a disease-causing genetic deletion. Instead of repairing the ...
Phys.org / Consumer confidence rises for second straight month; views remain downbeat amid high prices
Consumer sentiment confirmed its early-July reading, landing almost 12% above June, according to the University of Michigan Surveys of Consumers.
Phys.org / Stable DNA building blocks enable faster oligonucleotide synthesis without oxidation
The chemical synthesis of oligonucleotides (ONs) is central to modern molecular biology, diagnostics and nucleic acid therapeutics. While demand for high-quality ONs is increasing, the conventional synthetic method has long-standing ...
Phys.org / Gold-MXene catalyst converts nitrate to ammonia using sunlight and 1.5 volts
Plants need nitrogen fertilizers, which are usually ammonia-based. Ammonia is therefore one of the most important chemical products. However, its production is currently extremely energy-intensive. An international team from ...
