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 / 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 / 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 ...
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 / Climate change is driving rising agricultural water use in Central Asia
Even as farmers shift toward less water-intensive crops, climate change is pushing agricultural water consumption upward in Central Asia. A new study by IAMO researchers shows that rising temperatures and atmospheric water ...
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 / A little protein with a big role in building Earth's carbon fixing machinery
An international team of scientists has discovered that a small, low-abundance protein plays a surprisingly big role in assembling carboxysomes—specialized bacterial microcompartments that enable efficient carbon fixation ...
Phys.org / Temporal evolution of GRB 240825A afterglow provides insight into origins of optically dark gamma-ray bursts
Researchers from the Yunnan Observatories of the Chinese Academy of Sciences have conducted a new study on the temporal evolution of the afterglow from gamma-ray burst GRB 240825A. The study offers new evidence to better ...
Phys.org / Sea turtles are nesting earlier but producing fewer eggs, 17-year study finds
Climate change is reshaping life on Earth at an unprecedented pace. Across the globe, species are shifting their ranges, altering migration routes and breeding earlier in the year in response to rising temperatures. But while ...
