What is a unit of nature? New framework highlights challenges in biodiversity credit markets
Ecologists have devised a new framework to classify how biodiversity credit operators define what a unit of nature is. The new analysis demonstrates the challenges involved with devising a biodiversity credit market to fund nature recovery, and the r.....»»
Rethinking the quantum chip: Engineers present new design for superconducting quantum processor
Researchers at the UChicago Pritzker School of Molecular Engineering (UChicago PME) have realized a new design for a superconducting quantum processor, aiming at a potential architecture for the large-scale, durable devices the quantum revolution dem.....»»
Cosmic rays" vast energy traced to magnetic turbulence
Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles.....»»
Researchers call on European Commission to protect groundwater and subterranean life from pollution
The subterranean world holds a value that is often underestimated. Its significance seems to escape notice, particularly its vital role in storing drinking water—a resource long taken for granted—and its contribution to biodiversity, harboring un.....»»

In vivo electrochemistry could provide early detection of high-altitude hypoxic brain injury
People who climb too fast or too high risk acute altitude sickness, which can lead to life-threatening hypoxic brain injury. By using in vivo electrochemistry, researchers have demonstrated that characteristic changes occur in the oxygen content of v.....»»
In at least one leading company, foreign-born talents are paid less
In the national debate over legal immigration, the H-1B visa program has acquired a special significance. Immigration skeptics contend that the program—reserved for high-skilled foreign nationals working in tech and other lucrative industries—mig.....»»
Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
High heat is preferentially killing the young, not the old, research finds
Many recent studies assume that elderly people are at particular risk of dying from extreme heat as the planet warms. A new study of mortality in Mexico turns this assumption on its head: it shows that 75% of heat-related deaths are occurring among p.....»»
