Quantum scientists accurately measure power levels one trillion times lower than usual      (via sciencedaily.com)     Original source 

Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.

Deep sea surveys detect over five thousand new species in future mining hotspot      (via sciencedaily.com)     Original source 

There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science.

Global macrogenetic map of marine habitat-forming species      (via sciencedaily.com)     Original source 

Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.

Curved spacetime in a quantum simulator      (via sciencedaily.com)     Original source 

The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.

Exploring the underground connections between trees      (via sciencedaily.com)     Original source 

Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular 'mother-tree hypothesis'. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
