A genus of Australian ants, many of whose members prefer to forage in blistering temperatures of up to 50°C (122°F), is revised to include 74 new species. The ants include seed-eaters, ant and termite raiders, 'honeypot ants' that store nectar and honeydew, and numerous others whose biology is not yet understood. Some are bizarre: one species has eyes like inverted ice-cream cones. The revision is published in the open-access journal ZooKeys.
While football-related concussions have been top of mind in recent years, people have struggled to create technology to accurately measure them in real time. BYU mechanical engineering Ph.D. student Jake Merrell and a team of researchers across three BYU departments have developed and tested a nano composite smartfoam that can be placed inside a football helmet (and pads) to more accurately test the impact and power of hits.
Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new UBC study that suggests other small island nations might also consider adopting this strategy.
A study led by environmental health researchers at the University of Cincinnati (UC) College of Medicine finds that children in East Liverpool, Ohio with higher levels of Manganese (Mn) had lower IQ scores. The research appears online in the journal NeuroToxicology.
Some big plant-eating dinosaurs roaming present-day Utah some 75 million years ago were slurping up crustaceans on the side, a behavior that may have been tied to reproductive activities, says a new University of Colorado Boulder study.
Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.
A new study estimates employer-sponsored health plans spent at least $6 billion extra on infants born prematurely in 2013 and a substantial portion of that sum was spent on infants with major birth defects.
A remote cave in Eastern Turkmenistan was found to shelter a marvelous cave-adapted inhabitant that turned out to represent a species and genus new to science. This new troglodyte is the first of its order from Central Asia and the first strictly subterranean terrestrial creature recorded in the country. The study is published in the open-access journal Subterranean Biology.
Are quantum states real? This most fundamental question in quantum mechanics has not yet been satisfactorily resolved, although its realistic interpretation seems to have been rejected by various delayed-choice experiments. Recently, scientists from University of Science and Technology of China, Harbin University of Science and Technology and other collaborators propose and demonstrate a quantum twisted double-slit experiment, in which the physical reality of wavefunctions is confirmed for the first time.
The materiality exhibited by manmade polymers currently relies on simple chemical bonds and the sequence order taken by molecules in the polymer chain. We now no longer need to rely on fate to determine such materiality with this new technique for precisely defining polymer-chain order. This system uses highly specific 'grabber' ends on each molecule that bond with only one type of 'pin' end on another molecule.
