ITHACA, N.Y. - One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost.
Deaths from stroke in England halved during the first decade of the 21st century, mainly as a result of improved survival due to better care, finds a study published by The BMJ today.
The number of strokes, and the number of people who died from stroke, decreased by 20% and 40%, respectively, over this period.
But despite this overall reduction, the researchers warn that stroke rates actually increased in people aged under 55, suggesting that stroke prevention efforts need to be strengthened in younger adults.
Scientists at Tokyo Institute of Technology and Keio University investigated the excitation and detection of photogenerated coherent phonons in polar semiconductor GaAs through an ultrafast dual pump-probe laser for quantum interferometry.
Researchers at Tokyo Institute of Technology have found a simple, yet highly versatile, way to generate "chaotic signals" with various features. The technique consists of interconnecting three "ring oscillators," effectively making them compete against each other, while controlling their respective strengths and their linkages. The resulting device is rather small and efficient, thus suitable for emerging applications such as realizing wireless networks of sensors.
Invasive lionfish (Pterois volitans and P. miles) are now ubiquitous throughout the Caribbean and Western Atlantic on both shallow and deep reefs. While many invasive species disrupt natural ecosystems by spreading disease or competing for food and habitat, lionfish are particularly problematic owing to their voracious appetites and high reproductive capacities.
Worcester, Mass. - If a genetically or synthetically engineered organism is released into the environment, how will we know? How can we tell it apart from the millions of microorganisms that exist naturally in the wild? That's the challenge being taken on by a multi-institution research team, including Eric Young, assistant professor of chemical engineering at Worcester Polytechnic Institute (WPI), that is developing a biosecurity tool that can detect engineered microorganisms based on their unique DNA signatures.
Native Americans' use of fire to manage vegetation in what is now the Eastern United States was more profound than previously believed, according to a Penn State researcher who determined that forest composition change in the region was caused more by land use than climate change.
WASHINGTON, D.C., May 21, 2019 -- Superconductors' never-ending flow of electrical current could provide new options for energy storage and superefficient electrical transmission and generation, to name just a few benefits. But the signature zero electrical resistance of superconductors is reached only below a certain critical temperature, hundreds of degrees Celsius below freezing, and is very expensive to achieve.
How adult penguins fish and the body condition of their chicks are directly linked to local fish abundance, and could potentially inform fishery management, a new study has found.
The researchers studied an endangered African penguin colony during a rare three-year closure of commercial fisheries around Robben Island, South Africa, and their findings are published today in the Journal of Applied Ecology.
New research supports the effectiveness and safety of esketamine nasal spray in treating depression in people who have not responded to previous treatment. The research will be published online today in the American Journal of Psychiatry. This study is one of the key studies that led to the recent Food and Drug Administration (FDA) approval of esketamine nasal spray, in conjunction with an oral antidepressant, for use in people with treatment-resistant depression.
(New York, NY) - The International Pediatric MS Study Group (IPMSSG) has released updated standards for clinical trials involving children and teens with multiple sclerosis (MS). The new recommendations were published in the May 1, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The updated recommendations include:
A new framework to enable retailers to better position their products to consumers has been devised by Tamer Boyaci and Frank Huettner at ESMT Berlin together with Yalcin Akcay from Melbourne Business School. According to the researchers, consumers often lack the full information when making purchasing decisions on variety of products, from day-to-day items to luxuries such as holidays, resulting in them making poor choices, and superior products losing out on sales.
Philadelphia, May 20, 2019--Teen drivers diagnosed with attention-deficit hyperactivity disorder (ADHD) are significantly more likely to crash, be issued traffic and moving violations, and engage in risky driving behaviors than their peers without ADHD, according to a Children's Hospital of Philadelphia (CHOP) study published today in the journal Pediatrics.
ANN ARBOR, Mich. -- Despite evidence that helmets are critical to preventing head injuries, not all children wear them while biking, skateboarding and riding scooters, a new national poll finds.
Eighteen percent of parents say their child never wears a helmet on a bike ride, and even more say their kids skip helmets on a skateboard (58 percent) and scooter (61 percent), suggests the C.S. Mott Children's Hospital National Poll on Children's Health at the University of Michigan.
Many measures have been introduced around the world with the aim of reducing outdoor air pollution and concomitantly improving public health. These efforts include, for example, the regulation of industrial emissions, the establishment of low emission zones and the subsidies for public transport, as well as restrictions on the use of wood and coal for heating in private households. The link between these actions and improved air quality and health seems obvious, but it is actually very difficult to quantify their effects.
