According to an independent study released today by the International Institute for Applied Systems Analysis (IIASA) and the Council on Energy, Environment, and Water (CEEW), more than 674 million Indian citizens are likely to breathe air with high concentrations of PM2.5 in 2030, even if India were to comply with its existing pollution control policies and regulations.
HOKKAIDO, JAPAN (March 29, 2019) - Paleontologists from Hokkaido University in Japan, in cooperation with paleontologists from the Perot Museum of Nature and Science in Dallas, Texas, have discovered the first-confirmed occurrence of a lambeosaurine (crested 'duck-billed' dinosaur) from the Arctic - part of the skull of a lambeosaurine dinosaur from the Liscomb Bonebed (71-68 Ma) found on Alaska's North Slope. The bonebed was previously known to be rich in hadrosaurine hadrosaurids (non-crested 'duck-billed' dinosaurs).
Some diseases which are fatal in one species can cause only mild discomfort in another--but it's hard for scientists to predict how lethal a disease will be if it leaps across species.
However, a new paper published this week in the Proceedings of the National Academy of Sciences indicates that the evolutionary relationship between infected hosts can predict the impact of diseases.
Canadian researchers used data from the World Organisation for Animal Health to track diseases in domesticated mammals, tracing their paths and outcomes across the world.
Over 50 non-native species have found their way to the Galápagos Islands, almost 10 times more than scientists previously thought, reports a new study in Aquatic Invasions published Thursday, March 28.
The study, a joint effort of the Smithsonian Environmental Research Center, Williams College, and the Charles Darwin Foundation, documents 53 species of introduced marine animals in this UNESCO World Heritage Site, one of the largest marine protected areas on Earth. Before this study came out, scientists knew about only five.
RIVERSIDE, Calif. - Kangaroo rats are abundant and seemingly defenseless seed-eating rodents that have to contend with a host of nasty predators, including rattlesnakes -- venomous pit vipers well known for their deadly, lightning-quick strikes.
Research by a student-led team from UC Riverside, San Diego State University, and UC Davis now shows that desert kangaroo rats frequently foil snakes through a combination of fast reaction times, powerful evasive leaps, and mid-air, ninja-style kicks.
Biophysicists have used an automated method to model a living system -- the dynamics of a worm perceiving and escaping pain. The Proceedings of the National Academy of Sciences (PNAS) published the results, which worked with data from experiments on the C. elegans roundworm.
Tracking animals using DNA signatures are ideally suited to answer the pressing questions required to conserve the world's wildlife, providing benefits over invasive methods such as ear tags and collars, according to a new study by University of Alberta biologists.
Genetic tagging, or the identification and tracking of individual animals using DNA, is a non-invasive method of conducting research that uses samples from shed hair, feathers, feces, or saliva.
Joint replacements are among the most common elective surgeries -- but around one in 100 patients suffer post-surgical infections, turning a routine procedure into an expensive and dangerous ordeal. Now, researchers at Stevens Institute of Technology have developed a "self-defensive surface" for these implants that release targeted micro-doses of antibiotics when bacteria approach, potentially sharply reducing infection rates.
A team of biologists and physicists, led by the University of Bristol, have uncovered new insights into how antlions - one of the fiercest and most terrifying predators in the insect kingdom - build their deadly pit traps.
Antlions - with their nightmarish fish-hook sharp jaws which can drain the bodily fluids of its victims within minutes - are iconic within entomology and they have been studied for 200 years.
It was known that they make pits lined with fine sand grains and that they throw large debris out of the pit.
Newton, Mass. (March 26, 2019) - Being a gymnast has its risks--the countless jumps, twists, and landings can take a toll on the body. But there's another, invisible risk: the equipment used in training contains hazardous flame retardant chemicals that accumulate in air and dust, and eventually end up in the athletes' bodies. A new study, however, shows that replacing the foam cubes in the landing pits with flame retardant-free alternatives can significantly lower their exposures.
