Less parental warmth and more harshness in the home environment affect how aggressive children become and whether they lack empathy and a moral compass, a set of characteristics known as callous-unemotional (CU) traits, according to findings from the University of Pennsylvania, the University of Michigan, and Michigan State University. The work was published in the Journal of the American Academy of Child and Adolescent Psychiatry.
As Europe's most active volcano, Mount Etna is intensively monitored by scientists and Italian authorities. Satellite-based measurements have shown that the southeastern flank of the volcano is slowly sliding towards the sea, while the other slopes are largely stable. To date, it has been entirely unknown if and how movement continues under water, as satellite-based measurements are impossible below the ocean surface.
LA JOLLA, CA - Oct. 10, 2018 - If you've ever been sunburned, you've experienced the dreaded pain of putting on a shirt the next day. Fabric that should feel soft turns into a layer of painful pressure. That kind of pain-from what should feel like a gentle touch-is called allodynia, and it's a fact of life for many people who suffer from chronic conditions, such as fibromyalgia or nerve damage from chemotherapy. There are limited options to help these patients.
A rose by any other name is still a rose. The same, it turns out, can be said for cannabis.
Newly published research from UBC's Okanagan campus has determined that many strains of cannabis have virtually identical levels of tetrahydrocannabinol (THC) and cannabidiol (CBD), despite their unique street names.
As Hurricane Michael barrels toward the U.S. states along the northwestern Gulf of Mexico, and Tropical Storm Leslie lingers in the Central Atlantic, Tropical Storm Nadine has formed off the west coast of Africa in the far eastern Atlantic. NASA-NOAA's Suomi NPP satellite provided a visible image of the new named storm.
On Oct. 9, the VIIRS instrument aboard NASA-NOAA's Suomi satellite provided a visible look at Tropical Storm Nadine. The bulk of storms were east to south of center and wrapping into the low-level center.
High levels of air pollutants, especially fine particulate matter (PM2.5) and to a lesser extent, ozone, may be linked to a heightened risk of developing mouth cancer, suggests the first study of its kind, published online in the Journal of Investigative Medicine.
The number of new cases, and deaths from, mouth cancer is increasing in many parts of the world. Known risk factors include smoking, drinking, human papilloma virus, and in parts of South East Asia, the chewing of betel quid ('paan'), a mix of ingredients wrapped in betel leaf.
The children of families who fall upon hard times are at significantly greater risk of being involved in violent crime and harming themselves as young adults, according to a major new study.
The research by University of Manchester epidemiologists is a major addition to our understanding of the risk factors for self-harm and violent criminality.
The knowledge was generated from a study funded by the European Research Council of the young adult population of Denmark published today in The Lancet Public Health.
A bacterium named Moorella thermoacetica won't work for free. But UC Berkeley researchers have figured out it has an appetite for gold. And in exchange for this special treat, the bacterium has revealed a more efficient path to producing solar fuels through artificial photosynthesis.
Philadelphia, PA, October 9, 2018 - Each year 15 million infants are born preterm and face high risks of short- and long-term complications, including sepsis, severe inflammation of the gut, and neurodevelopmental disorders.
A study led by researchers at Université de Montréal quantifies for the first time the maximum amount of nutrients - specifically, phosphorus - that can accumulate in a watershed before additional pollution is discharged into downriver ecosystems.
That average threshold amount is 2.1 tonnes per square kilometre of land, the researchers estimate in their study published today in Nature Geoscience. "Beyond this, further phosphorus inputs to watersheds cause a significant acceleration of (phosphorus) loss in runoff."
NASA's Aqua satellite passed over the Central Atlantic Ocean and obtained infrared data on Leslie, now weakened to a large tropical storm.
The National Hurricane Center or NHC said that Leslie remains a large tropical storm, with tropical-storm-force winds extending outward up to 290 miles (465 km) from the center. Because of the size and strength of Tropical Storm Leslie, waves from Leslie are expected to increase along the coasts of Atlantic Canada and New England today, Oct. 5.
TORONTO, ON - Scientists at the University of Toronto have found a way to select the outcome of chemical reaction by employing an elusive and long-sought factor known as the 'impact parameter'.
The team of U of T chemists, led by Nobel Prize-winning researcher John Polanyi, have found a means to select the impact parameter or miss-distance by which a reagent molecule misses a target molecule, thereby altering the products of chemical reaction. The findings are published today in Science Advances.
BLOOMINGTON, Ind. -- More and more breweries are investing in practices to save energy and reduce greenhouse gases. Will it pay off? A study by Indiana University researchers suggests it may.
Drawing on survey research, they find that a majority of U.S. beer drinkers would be willing to pay more for beer produced with sustainable practices. On average, they would pay about $1.30 more per six-pack.
Global sustainability is important now more than ever due to increasing urban populations and the resulting stress it can have on natural resources. But increased populations in cities may lead to greater efficiency, as a team of Penn State researchers discovered when they analyzed the water footprint of 65 mid- to large-sized U.S. cities.
Scientists using a powerful new technology that sequences RNA in 20,000 individual cell nuclei have uncovered new insights into biological events in heart disease. In animal studies, the researchers identified a broad variety of cell types in both healthy and diseased hearts, and investigated in rich detail the "transcriptional landscape," in which DNA transfers genetic information into RNA and proteins.
