Culture
For many people, climate change feels like a distant threat -- something that happens far away, or far off in the future. Scientists and climate communicators often think that if everyone saw the devastating impacts of climate change, we'd all be more likely to accept it as real, and that accepting climate science is essential to taking action against it. A recent study, published in Regional Environmental Change, challenges the latter part of this assumption.
"Green revolution" in the early 1950s, the extensive cultivation of Dwarf Rice solves the food problem in developing countries. At present, chronic infection with hepatitis B virus (HBV) has been a major public health problem. According to the announcement from World Health Organization (WHO), an estimated 257 million people are chronically infected with hepatitis B.
Replenishing venom takes time and energy - so it pays to be stingy with stings.
According to researchers at the Australian National Institute of Tropical Health and Medicine, scorpions adapt their bodies, their behavior and even the composition of their venom, for efficient control of prey and predators.
Writing in Frontiers in Ecology and Evolution, they say it's not just the size of the stinger, but also how it's used that matters.
Social media-based movements like #BlackLivesMatter and #SayHerName have taken off over the past decade as a response to highly scrutinized police shootings of African American people. Recordings from body cameras or bystanders are frequently posted online and shared by activists and others as a way to press for police accountability.
But those videos may also have deleterious effects on the mental health of young members of the same racial communities as the victims in those shootings, suggests a new study published today in the Journal of Adolescent Health.
The search for dark matter is expanding. And going small.
While dark matter abounds in the universe - it is by far the most common form of matter, making up about 85 percent of the universe's total - it also hides in plain sight. We don't yet know what it's made of, though we can witness its gravitational pull on known matter.
Theorized weakly interacting massive particles, or WIMPs, have been among the cast of likely suspects comprising dark matter, but they haven't yet shown up where scientists had expected them.
Casting many small nets
(June 7, 2019) –- For more than a year, GozNym, a gang of five Russian cyber criminals, stole login credentials and emptied bank accounts from unaware Americans. To detect and quickly respond to escalating cyber-attacks like these, researchers at The University of Texas at San Antonio (UTSA) have developed the first framework to score the agility of cyber attackers and defenders. The cyber agility project was funded by the Army Research Office.
Nanoengineers at the University of California San Diego have developed new deep learning models that can accurately predict the properties of molecules and crystals. By enabling almost instantaneous property predictions, these deep learning models provide researchers the means to rapidly scan the nearly-infinite universe of compounds to discover potentially transformative materials for various technological applications, such as high-energy-density Li-ion batteries, warm-white LEDs, and better photovoltaics.
Groundwater experts from around Australia have repeated calls for further investigations into the potential effects on heritage groundwater reserves in central Queensland if the giant Adani Carmichael coalmine gets the final regulatory go-ahead.
Concerns the ancient Doongmabulla Springs face a 'reasonable threat of extinction' from Adani's proposed Galilee Basin coalmine are raised in a new position paper, which echoes previous research by CSIRO and Geoscience Australia.
Since the output of renewable energy such as photovoltaic generation tends to fluctuate, the power system can be viewed as a large-scale complex system with uncertainty. To stabilize the balance of supply and demand of electricity, we need an energy management system to control this. In recent years, energy management systems have been actively researched against the background of the liberalization of power and the spread of smart meters that visualize the power consumption.
Researchers from the University of Hong Kong, University of Tennessee, University of British Columbia, and Arizona State University published a new paper in the Journal of Marketing that seeks the optimal strategy for communicating the value of cocreated innovations in order to drive consumer purchase and acceptance in the marketplace.
The study forthcoming in the July issue of the Journal of Marketing, titled "Successfully Communicating a Cocreated Innovation," is authored by Helen Si Wang, Charles Noble, Darren Dahl, and Sungho Park.
A meta-analysis of dietary information recorded in the bones of ancient animals and humans recovered from sites scattered across the Eurasian steppe, from the Caucasus region to Mongolia, demonstrates that pastoralists spread domesticated crops across the steppe through their trade and social networks. Researchers from Kiel University sifted through previously published stable isotopic data and applied new quantitative analyses that calibrate human dietary intake against environmental inputs.
Evidence for the ancient, 1.2 billion years old, meteorite strike, was first discovered in 2008 near Ullapool, NW Scotland by scientists from Oxford and Aberdeen Universities. The thickness and extent of the debris deposit they found suggested the impact crater - made by a meteorite estimated at 1km wide - was close to the coast, but its precise location remained a mystery.
A simple tweak to the sleeping patterns of 'night owls' - people with extreme late sleeping and waking habits - could lead to significant improvements in sleep/wake timings, improved performance in the mornings, better eating habits and a decrease in depression and stress.
New international research by the Universities of Birmingham and Surrey in the UK, and Monash University in Australia, showed that, over a three-week period, it was possible to shift the circadian rhythm of 'night owls' using non-pharmacological and practical interventions.
Hamilton, ON (June 9, 2019) - A clinical trial that followed more than 9,900 people in 24 countries has found that the drug dulaglutide reduced cardiovascular events and kidney problems in middle-aged and older people with Type 2 diabetes.
During more than five years of follow-up, cardiovascular events like heart attacks and strokes were reduced by 12% in people taking dulaglutide compared to people taking a placebo. This effect was seen in both men and women with or without previous cardiovascular disease.
