High H5N1 influenza levels found in mice given raw milk from infected dairy cows
Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises...
Entomologist sheds light on 250-year-old mystery of the German cockroach
Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an...
Virginia Tech Physicists Propose Path to Faster, More Flexible Robots
In a May 15 paper released in the journal Physical Review Letters, Virginia Tech physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Controlling Water, Transforming Greenhouse Gases
Scientists looking to convert carbon dioxide into clean fuels and useful chemicals often make hydrogen gas and carbonates as unwanted byproducts.
Ambitious Targets Are Needed to End Ocean Plastic Pollution by 2100
Research suggests that plastic pollution must be reduced by at least 5% every year to make progress towards UN targets by the end of the century.
Developing novel methods to detect antibiotics in vegetables and earthworms
Researchers have managed to analyze, simultaneously, several families of antibiotics in vegetables and earthworms. Sampling carried out in various locations has yielded data on the existence of antimicrobial agents and their derivatives in vegetables. In this respect, Vergara stresses the need for further research to address the problem of contamination...
Intriguing nearby world sized between Earth, Venus
Astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away.
Iron could be key to less expensive, greener lithium-ion batteries, research finds
Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Charting a pathway to next-gen biofuels
From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
