Phys.org / Migratory birds may carry fewer parasites between islands than expected, DNA shows
A new study published in the Journal of Helminthology by researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences, together with collaborators from Greenland and the Faroe ...
Phys.org / Researchers break a fundamental rule to create a new concept: Heat that can be directed and 'programmed'
Normally, a material absorbs and emits heat in a linked way: A surface that absorbs heat well at a certain wavelength and direction will also emit heat in the same way. This fundamental relationship, known as reciprocity, ...
Phys.org / Medieval text family trees suggest 60% of works vanished over centuries
For every King Arthur or Roland, whose adventures readers can still enjoy today, another hero of ancient literature may have been lost forever. Before the printing press, texts were copied manually. This process introduced ...
Phys.org / Where rivers face collapse: New tool shows where conservation dollars can do most good
Freshwater ecosystems are under growing pressure worldwide, but conservation resources are limited. A framework developed by IIASA researchers and partners can help identify where conservation could prevent biodiversity loss ...
Phys.org / Saturn-ring-like laser emission from chiral polymeric microspheres
Controlling light within microscopic spaces is crucial for next-generation optical devices such as photonic integrated circuits and localized sensors. Microspheres formed of luminescent π-conjugated polymers act as optical ...
Phys.org / New ultrathin lens focuses light into an optical needle
Researchers have created a special flat lens that shapes light into an optical needle—a thin beam that stays tightly focused over a long distance. Combining this lens, which is about 7 microns thick, with optical coherence ...
Phys.org / South Pole Telescope analysis releases new catalog of more than 7,000 galaxy clusters
Researchers working with data from the South Pole Telescope have released a major catalog of galaxy clusters, giving scientists a powerful new tool for studying how the universe grew and changed over billions of years. The ...
Phys.org / Day-night ocean warming helps explain why El Niño outpaces La Niña in models
Researchers have long known that there is an asymmetry in the El Niño-Southern Oscillation (ENSO), the confluence of wind and water currents that creates warm El Niño events and cooler La Niña events. Large-scale climate ...
Phys.org / Satellite record reveals US tidal wetland productivity rose 6% in 20 years
Carbon sequestration, climate regulation, biodiversity support and shoreline protection: These are all benefits provided by tidal wetlands. As the climate changes, the amount of carbon captured by these vital ecosystems may ...
Phys.org / Scientists enable DNA synthesis using only temperature instead of chemical reagents
"Complex chemical processes are essential for making DNA." This long-held assumption in the field of biotechnology has been overturned by a Korean research team. A KAIST research team has developed the world's first foundational ...
Phys.org / Magnetic octupole model captures domain-wall motion in noncollinear antiferromagnets
Researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign have developed the first magnetic multipole-based micromagnetic model for antiferromagnets. Published in Applied Physics ...
Phys.org / Pressure unlocks 3D superconductivity in tantalum disulfide at triple the temperature
Superconductors have long been considered a promising technology for the energy systems of the future. They can conduct electricity without resistance, thus eliminating both conduction losses and waste heat. Up to now, however, ...
