Phys.org / Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states
A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of operations depends on ...
Phys.org / Rich medieval Christians bought graves 'closer to God' despite leprosy stigma, archaeologists find
Medieval Christians in Denmark showed off their wealth in death by buying prestigious graves: the closer to the church, the higher the price. Researchers used these gravesites to investigate social exclusion based on illness, ...
Phys.org / Silicon metasurfaces boost optical image processing with passive intensity-based filtering
Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an especially impressive impact on science and technology. Now, researchers in the McKelvey School of ...
Phys.org / Oldest known reptile skin impressions dated to 298 million years found in Germany
An international research team led by Dr. Lorenzo Marchetti from the Museum für Naturkunde Berlin has described the oldest known impressions of reptile skin from the Thuringian Forest in central Germany. Particularly remarkable ...
Phys.org / Nanolaser on a chip could cut computer energy use in half
Researchers at DTU have developed a nanolaser that could be the key to much faster and much more energy-efficient computers, phones, and data centers. The technology offers the prospect of thousands of the new lasers being ...
Phys.org / New 3D printing ink uses 70% lignin and recycles with water
Additive manufacturing (AM) methods, such as 3D printing, enable the realization of objects with different geometric properties, by adding materials layer-by-layer to physically replicate a digital model. These methods are ...
Phys.org / Global analysis tracks 3,100 glacier surges as climate change rewrites the rules
While most of the world's glaciers are retreating as the climate warms, a small but significant population behaves very differently—and the consequences can be severe. A team of international scientists, led by the University ...
Phys.org / Yangtze River fishing ban halts seven decades of biodiversity decline
The Yangtze River Basin, a global biodiversity hotspot, has endured severe ecological degradation over several decades due to intense human activity, leading to a marked decline in aquatic biodiversity. In order to halt this ...
Phys.org / Rolling out the carpet for spin qubits with new chip architecture
Researchers at QuTech in Delft, The Netherlands, have developed a new chip architecture that could make it easier to test and scale up quantum processors based on semiconductor spin qubits. The platform, called QARPET (Qubit-Array ...
Phys.org / Physicists develop new protocol for building photonic graph states
Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty of making these graph states has left this value largely untapped. In a step forward for the field, ...
Phys.org / Plants retain a 'genetic memory' of past population crashes, study shows
Researchers at McGill University and the United States Forest Service have found that plants living in areas where human activity has caused population crashes carry long-lasting genetic traces of that history, such as reduced ...
Phys.org / Where'd you get that frog? Study traces illicit online amphibian trade
Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there's a dark side to the amphibian trade, according to a study ...
