Phys.org / The changing chemistry of invasive death cap mushrooms
The California Department of Public Health reported 39 related poisonings in the last three months, leading to the death of four people, at least three liver transplants, and many more people made sick. The culprit? In each ...
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 / 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 / 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 / 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 / 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 / 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 / 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 / Scientists say genetic analysis could greatly speed restoration of iconic American chestnut
Billions of American chestnut trees once covered the eastern United States. They soared in height, producing so many nuts that sellers moved them by train car. Every Christmas, they're called to mind by the holiday lyric ...
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 / 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 / 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 ...
