Chestnut Hill, Mass. (12/7/2018) - Like so many targets of scientific inquiry, the class of material referred to as the kagome magnet has proven to be a source of both frustration and amazement. Further revealing the quantum properties of the kagome magnet is seen as one of the primary challenges in fundamental physics - to both theorists and experimentalists.
Dec. 7, 2018--Vitamin C may reduce the harm done to lungs in infants born to mothers who smoke during their pregnancy, according to a randomized, controlled trial published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.
From iPhones on Earth to rovers on Mars, most electronics only function within a certain temperature range. By blending two organic materials together, researchers at Purdue University could create electronics that withstand extreme heat.
This new plastic material could reliably conduct electricity in up to 220 degrees Celsius (428 F), according to a paper published Thursday in the journal Science.
Advances in remote sensing technologies are helping scientists to better measure how global landscapes -- from forests to savanna -- are able to store carbon, a critical insight as they evaluate the potential role of ecosystems in mitigating climate change.
One factor often ignored in these carbon cycle assessments, however, is the role of wild animals. Compared with the vast capacity for trees and plants to store carbon, the conventional wisdom goes, low-abundant animal populations simply can't have much effect on these global systems.
Philadelphia, December 6, 2018 - In a web-based study reported in the Canadian Journal of Cardiology, more than three quarters of French-speaking adults in Quebec, Canada, fall short of meeting current dietary guidelines regarding consumption of fruits and vegetables, whole grains, sodium, and saturated fats.
The conservation of animals relies heavily on estimates of their numbers. Without knowing how many individuals there are, it is impossible to know whether a population is thriving or dying out--and whether conservation efforts are getting the job done. But making those estimates is no mean feat, reports Easton R. White of the Center for Population Biology at the University of California, Davis, writing in BioScience.
Tests on more than 100 sea turtles - spanning three oceans and all seven species - have revealed microplastics in the guts of every single turtle.
Researchers from the University of Exeter and Plymouth Marine Laboratory, working with the Greenpeace Research Laboratories, looked for synthetic particles (less than 5mm in length) including microplastics in 102 sea turtles in the Atlantic, Pacific and Mediterranean.
Environmental damage caused by human activity can reduce the number of plant and animal species dramatically. At the same time, only very little is known about how biodiversity recovers after the ecosystem has stopped being polluted and has been cleaned up. As was common in the mid-1900s, Lake Constance, one of the largest freshwater lakes in Europe, suffered from eutrophication, or nutrient contamination caused by agricultural and waste water run-off.
Philadelphia, December 4, 2018 -- Using an animal model of chronic stress, researchers at The Ohio State University have shown that the immune cells of the brain, called microglia, hold unique signatures of chronic stress that leave the animal more sensitive to future stressful experiences, evident by increased anxiety and immune responses. Eliminating microglia so that these "stress memories" could not be maintained did not prevent the increased anxiety in response to later stress but did prevent the hypersensitive immune response.
A unique experiment that explored how well algae grows in specific regions of the United States yielded data that could prove useful as the industry moves forward, according to research from the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) and Arizona State University (ASU).
