New technique to monitor evolution of magnetic disturbances from the Aurora Borealis
University of Warwick researchers link up over a hundred magnetometers to form a 'social network'
Magnetometers 'befriend' each other when the disturbance propagates to them
Space weather results in magnetic disturbances on the ground that can interfere with power distribution and electrical systems
Andrey Savchenko, Professor at the Higher School of Economics (HSE University), has developed a method that can help to enhance image identification on videos. In his project, a network was taught by a new algorithm and can now make decisions on image recognition and classification at a rate 10 times faster than before.
ITHACA, N.Y. - Researchers at Cornell University have shown for the first time that it is possible to reduce ageist attitudes, prejudices and stereotypes through education and intergenerational contact.
Ageism is the most socially acceptable prejudice on the planet, according to the World Health Organization (WHO). Discrimination against a person because of their age is more normalized than even racism or sexism. The WHO, which recruited the Cornell-led team to do the study, will use the research to inform its anti-ageism strategy.
San Antonio, Texas (June 19, 2019) - The global obesity epidemic is so far-reaching it now has an overarching name: globesity. Texas Biomed Staff Scientist Raul Bastarrachea, M.D., is part of a team that discovered a new mutation in the gene that regulates the key hormone suppressing hunger called leptin. This new mutation could help researchers understand why people develop excess of body fat. Dr. Bastarrachea's research is aimed at helping tackle metabolic disorders like cardiovascular disease and diabetes which are fueled by obesity and impact millions of people around the world.
Harmful algal blooms can cause big problems in coastal areas and lakes across the United States. When toxin-containing aquatic organisms multiply and form a bloom, it can sicken people and pets, contaminate drinking water, and force closures at boating and swimming sites.
With limited resources to monitor these often-unpredictable blooms, water managers are turning to new technologies from NASA and its partners to detect and keep track of potential hazards. This is particularly critical in lakes and reservoirs that people use for both recreation and water supply.
This image shows an irregular galaxy named IC 10, a member of the Local Group -- a collection of over 50 galaxies in our cosmic neighborhood that includes the Milky Way.
IC 10 is a remarkable object. It is the closest-known starburst galaxy, meaning that it is undergoing a furious bout of star formation fueled by ample supplies of cool hydrogen gas. This gas condenses into vast molecular clouds, which then form into dense knots where pressures and temperatures reach a point sufficient to ignite nuclear fusion, thus giving rise to new generations of stars.
A team of researchers has carried out a detailed study of the genomes of ruminants, giving new insight into their evolution and success.
Ruminants including deer and antelope, as well as sheep, goats, cattle and their wild relatives, have thrived in many ecosystems around the globe. They range in size from the tiny lesser mouse deer of Malaysia to the towering African giraffe.
As students learn a new concept, measuring how well they grasp it has often depended on traditional paper and pencil tests. Dartmouth researchers have developed a machine learning algorithm, which can be used to measure how well a student understands a concept based the student’s brain activity patterns. The findings are published in Nature Communications.
CHAPEL HILL, North Carolina -- Efforts to control health care costs in the United States often focus on the listed prescription drug prices, but a perspective published by the Journal of the American Medical Association suggests that unregulated pharmacy benefit manager practices also may contribute to escalating expenses.
More than three decades ago, scientists discovered that a chemical found in a synthetic opioid, MPTP, induced the onset of a form of Parkinson's disease. In a new study led by scientists from the School of Veterinary Medicine, researchers found that an enzyme in the body can metabolize compounds formed in the brain from alkaloids present in certain foods and tobacco into MPTP-like chemicals, triggering a neurodegenerative condition in mice.
Temperature-related mortality has been decreasing in Spain over the past four decades, according to a new study led by the Barcelona Institute for Global Health (ISGlobal), a research centre supported by "la Caixa". The study analysed the Spanish population's vulnerability to hot and cold temperatures in the context of global warming.
The CRISPR Journal announces the publication of its June 2019 issue. The Journal is dedicated to validating and publishing outstanding research and commentary on all aspects of CRISPR and gene editing, including CRISPR biology, technology, and genome editing, and commentary and debate of key policy, regulatory, and ethical issues affecting the field. The Journal, led by Editor-in-Chief Rodolphe Barrangou, PhD (North Carolina State University) and Executive Editor Dr. Kevin Davies, is published bimonthly in print and online.
A hydrogen-natural gas blend (HNGB) can be a game changer only if it can be stored safely and used as a sustainable clean energy resource. A recent study has suggested a new strategy for stably storing hydrogen, using natural gas as a stabilizer. The research proposed a practical gas phase modulator based synthesis of HNGB without generating chemical waste after dissociation for the immediate service.
The human brain consists of neurons arranged into microscopic columns. The cortex, which is the seat of most cerebral functions and forms the largest part of the brain, is divided into uncountable micro-columns. However, the exact development of this columnar structure is elusive to neuroscientists. A research team led by Makoto Sato, has recently reported their study describing the role of a specific protein in the growth of these columns.
