Since 2013, the Antarctic neutrino telescope IceCube has been detecting neutrinos that come from deep space. However, IceCube struggles to detect neutrinos with energies above 10¹? electronvolts because of the extremely low flux of these neutrinos at Earth. Now, researchers have obtained the first measurements of "radar echoes" from high energy particle cascades using a high energy electron beam at the SLAC National Accelerator Laboratory. Radar echoes are radio waves reflected from a conducting surface.
As the Democractic primaries accelerate and the 2020 presidential election approaches, many Americans still remember Russia's interference in the 2016 presidential election. Scientists have now developed a game theory model able to capture and assess election interference. Dewhurst et al. first created rational game players that were assigned different parameters.
Winds outside of Tropical Storm Gabekile are ripping the storm apart. NASA's Aqua satellite provided a visible image of the storm that showed strong northwesterly wind shear was adversely affecting the storm.
Gabekile formed on Feb. 15 and by the next day, it had rapidly intensified to hurricane-force with maximum sustained winds near 75 knots (86 mph/139 kph), then after encountering wind shear the storm quickly weakened.
Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that applying vibrational motion in a periodic manner may be the key to preventing dissipations of the desired electron states that would make advanced quantum computing and spintronics possible.
It takes a lot of fuel to launch something into space. Sending NASA's Space Shuttle into orbit required more than 3.5 million pounds of fuel, which is about 15 times heavier than a blue whale.
But a new type of engine -- called a rotating detonation engine -- promises to make rockets not only more fuel-efficient but also more lightweight and less complicated to construct. There's just one problem: Right now this engine is too unpredictable to be used in an actual rocket.
UCLA researchers have found that it is possible to assess a person's ability to feel empathy by studying their brain activity while they are resting rather than while they are engaged in specific tasks.
Australia's first plant foods - eaten by early populations 65,000 years ago - have been discovered in Arnhem Land.
Preserved as pieces of charcoal, the morsels were recovered from the debris of ancient cooking hearths at the Madjedbebe archaeological site, on Mirarr country in northern Australia.
University of Queensland archaeobotanist Anna Florin said a team of archaeologists and Traditional Owners identified 10 plant foods, including several types of fruits and nuts, underground storage organs ('roots and tubers'), and palm stem.
The Swedish team responsible for uterine transplantation research has, for the first time, transplanted a uterus from a deceased donor. The operation proceeded without complications and the recipient is doing well.
The transplant was done in December 2019 under the supervision of Mats Brannström, consultant physician and professor of obstetrics and gynecology at the University of Gothenburg. The research team plan to carry out another five transplants of a deceased donor's uterus in the course of 2020 and 2021.
Numerical simulations, generally based on equations that describe a given model and on initial data, are being applied in an ever-expanding range of scientific disciplines to approximate processes at given points in time and space. With so-called inverse problems, this critical data is missing--researchers must reconstruct approximations of the input data or of the model underlying observable data in order to generate the desired predictions.
An organic semiconductor photocatalyst that significantly enhances the generation of hydrogen gas could lead to more efficient energy storage technologies.
The combustion of fossil fuels is leading to dangerous climate change, driving the search for cleaner renewable energy sources. Solar energy is by far the most abundant renewable energy source, but unlocking its potential requires a way to store it for later use.
In the recent article published in Science Bulletin, the researchers develop an effective organic-cation intercalation strategy to manipulate the interlayer coupling of layered materials, and obtain a class of organic-inorganic hybrid crystals with tailored topological properties and enhanced superconductivities.
A University of Kent study has found that cultivated foods offer chimpanzees in West Africa more energetic benefits than wild foods available in the region.
The findings have made a significant development for our further understanding into human-primate coexistence and can help to inform conservation efforts for future improvement, particularly in locations where agricultural expansion is encroaching on tropical forests.
Exploiting a vulnerability in the mobile communication standard LTE, also known as 4G, researchers at Ruhr-Universität Bochum can impersonate mobile phone users. Consequently, they can book fee-based services in their name that are paid for via the mobile phone bill - for example, a subscription to streaming services.
Face blindness (prosopagnosia) is the inability to recognise faces. Much as people with dyslexia find it difficult to distinguish letters, people with face blindness are unable to "read" the special features that make faces unique, and which enable those without the condition to distinguish between people and recognise those we have met before.
Marine sediments cover more than two thirds of our planet's surface. Nevertheless, they are scarcely explored, especially in the deeper regions of the oceans. For their nutrition, the bacteria in the deep ocean are almost entirely dependent on remnants of organisms that trickle down from the upper water layers. Depending on how they process this material, it either remains in the depths of the ocean for a long time or moves back to the surface as carbon dioxide.
