Washington State health officials have urged consumers not to eat locally harvested raw oysters and other shellfish after an outbreak of intestinal disease caused by bacteria that multiplied rapidly after a recent “heat dome” baked the Pacific Northwest. State health…
UNIVERSITY PARK, Pa. — Infection with dengue virus makes mosquitoes more sensitive to warmer temperatures, according to new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to…
(Bigelow Laboratory for Ocean Sciences) Sweeping changes in marine nutrients may seem to be a likely consequence of increasing global temperatures; however, new research suggests that processes below the ocean surface could play a larger role than previously thought.
(Osaka City University) Using electron microscopy and high-speed atomic force microscopy, researchers show the internal molecular motor behind the gliding mechanism for Mycoplasma mobile to consist of two ATP synthase-like molecules. Sharing a similar structure with ATP synthase suggests a common evolutionary ancestor. This synthase-like ATPase is challenging the origin of cells and proteins themselves.
Student Invents Toilet That Converts Poop into Energy â And Pays in Digital Currency if You Help to Fill it!
One man’s trash is another man’s treasure, they say. Well, in a South Korean school, one man’s poo is another man’s pennies. The invention of a toilet that composts human excrement and turns it into methane biogas for use in the school’s energy system has the students there re-evaluating waste like never before, as the […]
(Florida Museum of Natural History) A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads.
(University of Pittsburgh) Contrary to popular belief, early bacterial evolution is not driven by random-point mutations.
(Woods Hole Oceanographic Institution) The hydrothermal vent fluids from the Gorda Ridge spreading center in the northeast Pacific Ocean create a biological hub of activity in the deep sea. There, in the dark ocean, a unique food web thrives not on photosynthesis but rather on chemical energy from the venting fluids. Among the creatures having a field day feasting at the Gorda Ridge vents is a diverse assortment of microbial eukaryotes, or protists, that graze on chemosynthetic bacteria and archaea.
(Cell Press) No longer science fiction, farm robots are already here–and they have created two possible extremes for the future of agriculture and its impacts on the environment, argues agricultural economist Thomas Daum in a Science & Society article published July 13 in the journal Trends in Ecology & Evolution.
(Trinity College Dublin) A team of geneticists and archaeologists from Ireland, France, Iran, Germany, and Austria has sequenced the DNA from a 1,600-year-old sheep mummy from an ancient Iranian salt mine, Chehrābād. This remarkable specimen has revealed sheep husbandry practices of the ancient Near East, as well as underlining how natural mummification can affect DNA degradation.
