A new paper in the May issue of Nature Communications demonstrates why keeping local lakes and other waterbodies clean produces cost-effective benefits locally and globally.
A novel technique for studying vortices in quantum fluids has been developed by physicists writing in Nature Communications. Turbulence in quantum systems, for example in superfluid helium 4, takes place on microscopic scales, and so far scientists have not had tools with sufficient precision to probe eddies this small. But now the Lancaster team, working at temperature of a few thousandths of a degree above absolute zero, has harnessed nanoscience to allow the detection of single quantum vortices.
Aqueducts are very impressive examples of the art of construction in the Roman Empire. Even today, they still provide us with new insights into aesthetic, practical, and technical aspects of construction and use. Scientists investigated the longest aqueduct of the time, the 426-kilometer-long Aqueduct of Valens supplying Constantinople, and revealed new insights into how this structure was maintained back in time.
A team has come up with a way to solve two longstanding puzzles: the ages of individual fluid-bearing diamonds, and the chemistry of their parent material. The research has allowed them to sketch out geologic events going back more than a billion years--a potential breakthrough not only in the study of diamonds, but of planetary evolution.
The first comprehensive comparison of 'degrowth' scenarios with established pathways to limit climate change highlights the risk of over-reliance on technological innovation to support continued global growth - which is assumed in established global climate modelling. Findings include: Technologically less risky 'degrowth' limits global warming to 1.5C while global GDP declines by 0.5% annually; a maximum 2C warming can be achieved with 0% GDP growth using available technology (i.e. in line with technological trends).
Targeting a heat production 'brake' on fat tissues may be a safer way to treat obesity than current medication.
Whole mitochondrial DNA sequencing of the three extant species of the aquatic mammal shows that they first split from their common ancestor after geological events isolated the South American region from the sea. The African species may have originated in migration borne by marine currents.
Trees lining a street may encourage people to take a longer stroll or choose to bike to work. New research shows how access to natural areas in cities can improve human health by supporting physical activity. The researchers plan to equip city planners with tools to create healthier, more sustainable cities around the world.
University of Montana Professor Mark Hebblewhite has joined an international team of 92 scientists and conservationists to create the first-ever global atlas of ungulate (hoofed mammal) migrations.
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection -- not deep wastewater injections -- can drive widespread deep earthquake activity in unconventional oil and gas production fields.
