Not long ago, getting a virus was about the worst thing computer users could expect in terms of system vulnerability. But in our current age of hyper-connectedness and the emerging Internet of Things, that's no longer the case. With connectivity, a new principle has emerged, one of universal concern to those who work in the area of systems control, like João Hespanha, a professor in the departments of Electrical and Computer Engineering, and Mechanical Engineering at UC Santa Barbara.
UNIVERSITY PARK, Pa. -- The reason why some people find it so hard to resist finishing an entire bag of chips or bowl of candy may lie with how their brain responds to food rewards, leaving them more vulnerable to overeating.
In a study with children, researchers found that when certain regions of the brain reacted more strongly to being rewarded with food than being rewarded with money, those children were more likely to overeat, even when the child wasn't hungry and regardless of if they were overweight or not.
China's power systems operators must invest in renewable energy to meet climate commitments. Wind power and PV are the lowest cost renewables, but they only deliver power when it's windy or sunny.
By contrast, more expensive Concentrated Solar Power (CSP), which can store its solar energy relatively inexpensively, and for long durations, can deliver power at any time, day or night.
Irvine, Calif., July 17, 2018 - In a first of its kind randomized trial, researchers from the UCI School of Medicine found therapy dogs to be effective in reducing the symptoms of attention deficit/hyperactivity disorder (ADHD) in children. The study's main outcomes were recently published by the American Psychological Association in the Society of Counseling Psychology's Human-Animal Interaction Bulletin (HAIB). Additional new findings were presented at the International Society for Anthrozoology 2018 Conference held July 2-5 in Sydney, Australia.
The MUSE (Multi Unit Spectroscopic Explorer - https://www.eso.org/public/teles-instr/paranal-observatory/vlt/vlt-instr/muse/) instrument on ESO's Very Large Telescope (VLT - http://www.eso.org/public/teles-instr/paranal-observatory/vlt/ ) works with an adap
Many people view the Tibetan Plateau, or "Roof of the World," as a pristine alpine environment, largely untouched by pollution. But researchers, reporting in ACS' journal Environmental Science & Technology, have now shown that traditional Tibetan medicine (TTM) exposes people and the environment to high levels of mercury and methylmercury.
NEW YORK...July 18, 2018 - A new highly maneuverable search and rescue robot that can creep, crawl and climb over rough terrain and through tight spaces has been developed by Ben-Gurion University of the Negev (BGU) researchers.
In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel - just as plants do - researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.
(Boston)--Researchers at Boston University School of Medicine (BUSM) have identified a new potential target protein (c-Cbl) they believe can help further the understanding of colon cancer and ultimately survival of patients with the disease.
They found colon cancer patients with high levels of c-Cbl lived longer than those with low c-Cbl. Even though scientists have studied this protein in other cancers, it has not been explored in colon cancer until now.
Sawtooth swings -- up-and-down ripples found in everything from stock prices on Wall Street to ocean waves -- occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some plasmas are free of sawtooth gyrations thanks to a mechanism that has long puzzled physicists.
Goofy, yellow and crooked: British smiles have sometimes had a less-than-flattering international image, but a new study has put tartar from our infamously bad teeth to good use.
Researchers analysing the teeth of Britons from the Iron Age to the modern day have unlocked the potential for using proteins in tooth tartar to reveal what our ancestors ate.
Dental plaque accumulates on the surface of teeth during life and is mineralised by components of saliva to form tartar or "dental calculus", entombing proteins from the food we eat in the process.
As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.
TD11W or Son-Tinh, is the first tropical cyclone of 2018 for the northern Philippines, where the storm is known locally as "Tropical Cyclone Henry."
WASHINGTON, D.C., July 17, 2018 -- In response to rising water scarcity, leading Argonne National Laboratory researcher Seth Darling describes the most advanced research innovations that could address global clean water accessibility. His comprehensive paper focuses on understanding and controlling the interfaces between materials and water.
Engineers at the University of California San Diego have shed new light on a scientific mystery regarding the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. The discovery also enriches fundamental understanding of general grain boundaries that often control the mechanical and physical properties of polycrystalline materials.
Scientists at Rutgers Brain Health Institute have discovered that a small group of brain cells in the hypothalamus called 'orexin' neurons could be a promising target for medications for controlling binge eating episodes in individuals with obesity. These neurons, named for the chemical messenger they use to communicate with other brain cells, have previously been shown to be important for addiction to several drugs, including cocaine.
