Of mice and babies: New animal model links blood transfusions to dangerous digestive disease in pree
Physicians have long suspected that red blood cell transfusions given to premature infants with anemia may put them in danger of developing necrotizing enterocolitis, a potentially lethal inflammatory disease of the intestines. However, solid evidence for the connection has been difficult to obtain in part because of the lack of a practical animal model able to accurately represent what physically occurs when a baby gets NEC.
CHAMPAIGN, Ill. -- Engineers at the University of Illinois have found a way to redirect misfit light waves to reduce energy loss during optical data transmission. In a study, researchers exploited an interaction between light and sound waves to suppress the scattering of light from material defects - which could lead to improved fiber optic communication. Their findings are published in the journal Optica.
PROVIDENCE, R.I. [Brown University] -- When acting as one part of a group charged with deciding how to punish someone -- a jury, for example -- individuals are swayed by their peers to punish more often than they would if deciding alone, a new study found.
HOUSTON - (Aug. 12, 2019) - A Rice University lab wants its products to look sharp, even at the nanoscale. Its latest creation is right on target.
The Rice lab of materials scientist Pulickel Ajayan has created unique two-dimensional flakes with two distinct personalities: molybdenum diselenide on one side of a sharp divide with rhenium diselenide on the other.
From all appearances, the two-toned material likes it that way, growing naturally -- though under tight conditions -- in a chemical vapor deposition furnace.
AUGUSTA, Ga. (Aug. 12, 2019) - When we race walk, for example, part of our healthy heart muscle may want a little more blood and oxygen, so our tiniest blood vessels send a message upstream to the larger vessels to send more.
Now researchers at the Medical College of Georgia at Augusta University have found that a chemical in our bodies known to help blood vessels dilate also sends that signal to the larger blood vessels that more blood is needed.
In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons - the vibration of atoms in solids - influence the materials' properties. Researchers from the University of Vienna, the Advanced Institute of Science and Technology in Japan, the company JEOL and La Sapienza University in Rome have developed a method capable to measure all phonons existing in a nanostructured material. This is a breakthrough in the analysis of nanoscale functional materials and devices.
HOUSTON - (Aug. 12, 2019) - Hexagonal-boron nitride is tough, but Rice University scientists are making it easier to get along with.
Two-dimensional h-BN, an insulating material also known as "white graphene," is four times stiffer than steel and an excellent conductor of heat, a benefit for composites that rely on it to enhance their properties.
Artificial intelligence-powered tools are rapidly becoming more accessible, including for people in the more remote corners of the globe. This is good news for smallholder farmers, who can use handheld technologies to run their farms more efficiently, linking them to markets, extension workers, satellite images, and climate information. The technology is also becoming a first line of defense against crop diseases and pests that can potentially destroy their harvests.
A new study shows that compared to younger adults, older adults are less distracted by negative information -- even in the earliest stages of attention.
EAST LANSING, Mich. - Transnational environmental crime - wildlife trafficking, illegal logging, dumping hazardous waste and more - takes an estimated $91 to $259 billion bite out of the global economy and has strong ties to organized crime finance, says a new study from Michigan State University and published in Nature Sustainability.
The African forest elephant (Loxodonta cyclotis), an endangered species, is often referred to as a "gardener" in recognition of its role as a disperser of fruit seeds from the large diversity of trees it feeds on as it moves through the continent's tropical forests, contributing to the germination of over 100 species that supply food or shelter to primates, birds, and insects.
NASA's Terra satellite passed over the Northwestern Pacific Ocean and captured a visible picture of the remnant clouds of deadly former Typhoon Lekima over eastern China.
On Aug. 12, 2019, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Lekima's remnant clouds. The remnants blanketed eastern China and the Korean Peninsula, also extending over part of the Yellow Sea.
Tiny Tropical Storm Henriette is the newest addition to the tropical cyclone line-up in the Eastern Pacific Ocean. The storm developed early on Aug. 12 and soon after the GPM satellite passed overhead and found heavy rain happening around its center.
Amidst a surge in research and media reports on the potentially negative consequences of "sexting," a University of Arizona researcher is exploring what motivates young people to send sexually explicit images of themselves via text message in the first place.
The explanation isn't as straightforward as one might think, especially when it comes to young women, says UA sociology doctoral student Morgan Johnstonbaugh, who presented her research during the American Sociological Association Annual Meeting in New York City over the weekend.
CHICAGO -- As people get older, they are more likely to condemn and want to punish others for acts that cause harm, even if no harm was intended, according to research presented at the annual convention of the American Psychological Association.
"Although older adults are capable of empathizing [about] someone's intentions when making a moral evaluation, they appear less likely to do so than younger individuals when those actions cause harm," said Janet Geipel, PhD, of the University of Chicago, who presented the research.
