How can birds that weigh less than a AA battery survive the immense power of Atlantic hurricanes? A new study in Ecology Letters finds that these coastal birds survive because their populations can absorb impacts and recover quickly from hurricanes--even storms many times larger than anything previously observed.
DeKalb, Ill. -- A team of scientists reports that they accurately predicted the nation's extensive tornado outbreak of late May 2019 nearly four weeks before it began.
The team's study, detailing factors that went into the forecast, was published recently in the journal, Geophysical Research Letters.
Just as the steam engine set the stage for the Industrial Revolution, and micro transistors sparked the digital age, nanoscale devices made from DNA are opening up a new era in bio-medical research and materials science.
The journal Science describes the emerging uses of DNA mechanical devices in a "Perspective" article by Khalid Salaita, a professor of chemistry at Emory University, and Aaron Blanchard, a graduate student in the Wallace H. Coulter Department of Biomedical Engineering, a joint program of Georgia Institute of Technology and Emory.
ABERDEEN PROVING GROUND, Md. (Sept. 18, 2019) -- Anticipating the technology and weapon systems of our future Army might not be entirely daunting, new Army research finds.
Trends in the progression of weapon systems from the early crossbowman to a musket to a military tank might help predict our future systems, according to a new study to be published in the Journal of Defense Modeling and Simulation, "Towards Universal Laws of Technology Evolution: Modeling Multi-century Advances in Mobile Direct Fire Systems."
Tropical Storm Jerry is the latest in a line of tropical cyclones to develop in the North Atlantic Ocean this season. NASA-NOAA's Suomi NPP satellite passed overhead and provided forecasters with a view of its structure that helped confirm it was organizing.
TORONTO, September 18, 2019 - When Canada's honey bees are thriving, they produce honey and pollinate valuable crops like blueberries, apples and hybrid canola seeds.
But the health of honey bees is declining, with more than a quarter of honey bee colonies dying each winter. These deaths have left beekeepers and government regulators struggling to find ways to quickly diagnose, manage and improve bee health.
State spending on transitional housing supports for youth "aging out" of foster care can make a big difference in preventing homelessness, incarceration, substance abuse and early childbirth, according to a new study by social work researchers at Case Western Reserve University.
Hurricane Kiko weakened to a tropical storm, but imagery from NASA-NOAA's Suomi NPP satellite showed that the storm has maintained strength in the circular area of powerful storms around the low-level center.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of Kiko on Sept. 17 revealed that powerful storms circled the low-level center. The image showed strong bands of thunderstorms located over the northern and western quadrants of the storm.
The same chemicals responsible for the pungent smell of a cannabis plant may also contribute to air pollution on a much larger scale, according to new research from the Desert Research Institute (DRI) and the Washoe County Health District (WCHD) in Reno, Nev.
In a new pilot study, DRI scientists visited four cannabis growing facilities in Nevada and California to learn about the chemicals that are emitted during the cultivation and processing of cannabis plants, and to evaluate the potential for larger-scale impacts to urban air quality.
In early test tube and mouse studies, investigators at Johns Hopkins Medicine and the Johns Hopkins Kimmel Cancer Center have found that nonmuscle myosin IIC (MYH14), a protein activated in response to mechanical stress, helps promote metastatic behavior in pancreatic cancer cells, and that the compound 4-hydroxyacetophenone (4-HAP), known to stiffen myosin IIC-containing cells, can send it into overdrive, overwhelmi
Organic solar cells (OSCs) have drawn great attention due to their advantages of making large area and flexible solar panels through the low-cost solution coating methods. Recently, the single-junction OSCs with over 16% power conversion efficiency (PCE) have been reported. However, photovoltaic performance of these cells is very sensitive to the variation in the active layer thickness, which has been recognized as a big challenge for practical application of OSCs.
RESEARCH TRIANGLE PARK, N.C. -- Less expensive, lighter and safer batteries are a vital need for warfighters; a new Army project may offer a solution.
The growing popularity of lithium-ion batteries in recent years has put a strain on the world's supply of cobalt and nickel -- two metals integral to current battery designs -- and sent prices surging.
ROCHESTER, Minn. -- In a small safety and feasibility clinical trial, Mayo Clinic researchers have demonstrated for the first time that senescent cells can be removed from the body using drugs termed "senolytics". The result was verified not only in analysis of blood but also in changes in skin and fat tissue senescent cell abundance. The findings appear in the journal EBioMedicine.
One in four teachers work more than 60 hours a week and many work in the evenings, despite successive government promises to reduce their hours, according to a new UCL-led study.
The paper, published today and funded by the Nuffield Foundation, is the first piece of research to look at data from more than 40,000 primary and secondary teachers in England collected between 1992 and 2017.
How to design cities that encourage physical activity among the citizens? Coinciding with the European Mobility Week, the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa", has published a study describing the urban characteristics that encourage people to choose walking for travel, instead of a motorized vehicle, with the benefits this entails: more physical activity and less air pollution, which result in improved health.
