The increasing threat of foreign interference in elections has driven six nations to take similar approaches to combat this pervasive threat. A review of the details to their responses brings out valuable differences and insights. These are presented in a forthcoming special issue of the peer-reviewed Election Law Journal.
The American pika is a charismatic, diminutive relative of rabbits that some researchers say is at high risk of extinction due to climate change. Pikas typically live in cool habitats, often in mountains, under rocks and boulders. Because pikas are sensitive to high temperatures, some researchers predict that, as the Earth's temperature rises, pikas will have to move ever higher elevations until...
For vegetable growers, weeds can mean lost income from reduced yield and foreign plant matter contaminating the harvest. But for many crops, particularly vegetable legumes, weed management options are very limited.
Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Nangka's rainfall rates as the storm soaked Hainan Island, China early on Oct. 13 (EDT).
NASA's Terra satellite obtained visible imagery as Tropical Storm Delta made landfall in Louisiana and moved northeastward soaking the U.S. southeast and Mid-Atlantic states.
Kurt looks and acts like any other young horse. He scampers and strides on springy legs, testing their strength. When it's time to recharge, he nuzzles up to his mother for some nourishing milk.
Ocean waves represent an abundant source of renewable energy. But to best use this natural resource, wave-energy converters need to be capable of physically handling ocean waves of different strengths without capsizing.
A study by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), the Universidad Complutense (UCM), Universidad de Girona (UdG), and the Institute for Bioengineering of Catalonia (IBEC), working together with other international centers, has overcome one of the key hurdles to the use of nanorobots powered by lipases, enzymes that play essential roles in digestion by...
A seemingly small one-to-two degree change in the global climate can dramatically alter weather-related hazards. Given that such a small change can result in such big impacts, it is important to have the most accurate information possible when studying the impact of climate change. This can be especially challenging in data sparse areas like Africa, where some of the most dangerous hazards are...
How can consumers be encouraged to take better care of public goods and resources? That's the question posed in a new research paper co-authored by Collen P. Kirk, D.P.S., associate professor of marketing at New York Institute of Technology, in the Journal of Marketing.
Optical spectrometers are instruments with a wide variety of uses. By measuring the intensity of light across different wavelengths, they can be used to image tissues or measure the chemical composition of everything from a distant galaxy to a leaf. Now researchers at the UC Davis Department of Biomedical Engineering have come up a with a new, rapid method for characterizing and calibrating...
Sequencing RNA from individual cells can reveal a great deal of information about what those cells are doing in the body. MIT researchers have now greatly boosted the amount of information gleaned from each of those cells, by modifying the commonly used Seq-Well technique.
It was just a year ago when Kevin Patel stood before a cheering climate change rally in New York and proclaimed that his generation would be the one to change the fate of the planet.
A survey of maritime infrastructure engineers by University of Rhode Island researchers found that the rising sea level is often not factored into designs of ports, breakwaters, fishing piers and other coastal infrastructure.
California's siege of wildfires has significantly quieted but forecasters warned Tuesday that a fall heat wave could bring back critical fire weather conditions this week.
Blue Origin, the US space company founded by billionaire Jeff Bezos, succeeded Tuesday in its latest test flight of its rocket aimed at one day taking tourists to space, even as the date of the first crewed launch remains unclear.
Two Southwest Research Institute (SwRI) experi-ments were aboard Blue Origin's New Shepard suborbital rocket today, which launched from Van Horn, Texas. The Box of Rocks Experiment II (BORE II) tested a new technology for magnetically attaching to and sampling asteroids. The second experi-ment evaluated a tapered liquid acquisition device (LAD) designed to safely deliver liquid propellant to a...
Researchers from MIPT have developed a prototype detector of solar particles. The device is capable of picking up protons at kinetic energies between 10 and 100 megaelectronvolts, and electrons at 1-10 MeV. This covers most of the high-energy particle flux coming from the Sun. The new detector can improve radiation protection for astronauts and spaceships, as well as advancing our understanding of...
The American Statistical Association Board of Directors has endorsed the recommendations of the 2020 Census Quality Indicators report, written by a task force of census experts to shed light on the quality, accuracy, and coverage of the 2020 Census counts. The task force, co-chaired by former US Chief Statistician Nancy Potok and ASA President-elect Robert Santos, was formed in early September in...
Steam-assisted oil extraction methods for heavy deposits have long been the focus of attention at Kazan Federal University. In particular, much attention is paid to in-situ combustion catalysts.
Storage jars form one of the main ceramic types which were produced and abundantly used ever since pottery was invented. The need to collect, store, and distribute agricultural products such as grains, oils and wine in large vessels has littered excavation sites with an abundance of ceramic jar fragments of various designs, sizes and shapes. However, for all of their variety, three Israeli...
Powerful picosecond generators are in demand in various fields of experimental electrophysics to produce ultrashort electron beams and X-ray pulses in vacuum diodes and to form runaway electron flows in gases.
For decades, biologists have captured tiny sea star larvae in their nets that did not match the adults of any known species. A Smithsonian team recently discovered what these larvae grow up to be and how a special superpower may help them move around the world. Their results are published online in the Biological Bulletin.
University of Guam researchers continue to expand knowledge of a unique group of plants called cycads. The world's contemporary cycad plants depend on small insects for pollination services. The Guam team's 2017 discovery of the new Cycadophila samara beetle and its pollination of cycads is now contributing to an international effort to more fully understand the intimate relationship between plant...
