An international group of leading scientists call for an urgent change in the governance of urban expansion as the world's cities continue to grow at unprecedented rates.
Teaching nature to break human-made chemical bonds
A newly evolved enzyme could one day make silicone compounds biodegradable.
Tiny ant species disrupts lion’s hunting behavior
Data gathered through years of observation reveal an innocuous-seeming ant is disrupting an ecosystem in East Africa, illustrating the complex web of interactions among ants, trees, lions, zebras and buffaloes.
World’s first successful embryo transfer in rhinos paves the way for saving the northern white rhinos from extinction
Scientists have succeeded in achieving the world's first pregnancy of a rhinoceros after an embryo transfer. The southern white rhino embryo was produced in vitro from collected egg cells and sperm and transferred into a southern white rhino surrogate mother at the Ol Pejeta Conservancy in Kenya on September 24,...
Researchers find new multiphoton effect within quantum interference of light
An international team of researchers has disproved a previously held assumption about the impact of multiphoton components in interference effects of thermal fields (e.g. sunlight) and parametric single photons (generated in non-linear crystals).
Marine heat waves trigger shift in hatch dates and early growth of Pacific cod
Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have...
Injectable water filtration system could improve access to clean drinking water around the world
A new portable filtration system collects dirty water with a syringe and injects it into a hydrogel filter that weeds out nearly all tiny particles.
Uncovering the secrets behind the silent flight of owls
Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers has uncovered the effects of these micro-fringes on the sound and aerodynamic performance of owl wings through computational fluid...
Records of cometary dust hitting the asteroid Ryugu
The Hayabusa2 mission that collected samples from the asteroid Ryugu has provided a treasure trove of insights into our solar system. After analyzing samples further, a team of researchers have unearthed evidence that cometary organic matter was transported from space to the near-Earth region.
Office air conditioning can reduce the risk of harm from wildfire smoke
Air conditioning doesn't just cool the air -- it can also reduce the risk of harm from wildfire smoke, new research suggests.
