NASA's Aqua Satellite provides a variety of data on tropical cyclones including cloud heights and cloud top temperatures. Aqua examined those factors in Tropical Storm Kiko before wind shear began to affect it and weaken the storm.
Hey, physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials - members of the platinum family - when they are ultra-thin.
Their technique combines traditional 'acoustic mapping' with a newer method called 'full waveform inversion'. They found their new method enhanced their view of rocks along a fault line - a break in the Earth's crust - off the east coast of New Zealand's North Island.
The researchers hope that their clearer view of the rocks around these fault lines - whose movements can trigger earthquakes and subsequent tsunamis - will help them better understand why such events happen.
MADISON, Wis., Sept. 24, 2019 - In California, the state with more building destruction by wildfire than all of the other states combined, new research by a U.S. Department of Agriculture Forest Service scientist and University of Wisconsin-Madison partners found something surprising. Over nearly three decades, half of all buildings destroyed by wildfire in California were located in an area that is described as having less of the grasses, bushes and trees that are thought to fuel fire in the wildland-urban interface, or WUI.
SILVER SPRING, Md.--Healthcare practitioners and researchers have a new tool to combat obesity in primary care settings, according to a study published in Obesity, the flagship journal of The Obesity Society.
According to a recent study published in Proceedings of the National Academy of Sciences of the United States of America, the biological clock influences immune response efficacy. Indeed, CD8 T cells, which are essential to fight infections and cancers, function very differently according to the time of day. The study was carried out by a team of researchers led by Nicolas Cermakian, PhD, of the Douglas Research Centre, and Nathalie Labrecque, PhD, of the Maisonneuve-Rosemont Hospital Research Centre.
NASA-NOAA's Suomi NPP satellite passed over the Caribbean Sea and used infrared light to obtain temperature information about Karen's cloud tops. Data showed powerful thunderstorms re-developed in around the storm's center as it strengthened back into a tropical storm.
Insulin-like growth factor 1 (IGF1) is essential for allowing tendons to adapt to physical activity and grow properly, according to basic science research by investigators at Hospital for Special Surgery (HSS). The findings provide a strong rationale for pursuing clinical trials to explore IGF1 as a new target for treating tendon injuries in humans.
Annapolis, MD; September 24, 2019--In 1999, West Nile virus was detected in the United States for the first time, and within five years it had spread from New York across the contiguous United States and into Canada, Mexico, and Central and South America. Transmitted to humans by mosquitoes that feed on infected birds, West Nile virus has served as a wake-up call to the challenge of preventing the spread of mosquito-borne diseases in the era of globalized trade and travel.
Cells that become senescent irrevocably stop dividing under stress, spewing out a mix of inflammatory proteins that lead to chronic inflammation as more and more of the cells accumulate over time. Publishing in the September 24 edition of Cell Reports, researchers at the Buck Institute identified 44 specific senescence-associated proteins that are involved in blood clotting, marking the first time that cellular senescence has been associated with age-related blood clots.
BOSTON (Sept. 24, 2019, 11:00 a.m. ET)--Despite years of steady advice and guidance on healthy eating, a 'report card' on the American diet shows adults are still consuming too many low-quality carbohydrates and more saturated fat than recommended, according to researchers at the Friedman School of Nutrition Science and Policy at Tufts University and the Harvard T.H. Chan School of Public Health.
WASHINGTON, D.C., September 24, 2019 -- Being able to accurately forecast how much solar energy reaches the surface of the Earth is key to guiding decisions for running solar power plants.
While day-ahead forecasts have become more accurate in recent years, the solar community lacks a unified verification procedure, and assessing how one forecast compares to another is difficult. New work in the Journal of Renewable and Sustainable Energy, from AIP Publishing, looks to provide a standard of reference to the field.
WASHINGTON, D.C., September 24, 2019 -- By studying the brain dynamics of 28 subjects with epilepsy, scientists demonstrated there is no evidence for a previously suspected warning sign for seizures known as "critical slowing down."
In 2013, some of the first seizure-prediction devices were developed and successfully tested. Although extensive research efforts have successfully identified predictors of imminent seizures, the concept of critical slowing down as an index for seizure susceptibility has been controversial and remained unproven.
According to a new study carried out at the University of Eastern Finland, the distribution of drug molecules within the brain can be improved by utilizing LAT1, which is expressed highly in the brain. By converting drug molecules temporarily into prodrugs, derivatives that can utilize LAT1 for cell entry and subsequently release the active parent drug within the target cells. This way one can achieve many times higher concentrations compared to the treatment with the parent drugs alone, which cannot utilize LAT1.
Today's electronics industry is increasingly focusing on computers or smartphones with screens that can be folded or rolled. Smart clothing items make use of wearable micro-devices or sensors to monitor bodily functions, for example. However, all these devices need an energy source, which is usually a lithium-ion battery. Unfortunately, commercial batteries are typically heavy and rigid, making it fundamentally unsuitable for applications in flexible electronics or textiles.
