Today's weather forecasts come from some of the most powerful computers on Earth. The huge machines churn through millions of calculations to solve equations to predict temperature, wind, rainfall and other weather events. A forecast's combined need for speed and accuracy taxes even the most modern computers.
A team of researchers from Russia, the United States, and China led by Skoltech Professor Artem R. Oganov has discovered an unexpected very complex europium hydride, Eu8H46. The paper detailing the discovery has been published in The Journal of Physical Chemistry Letters.
Tifton, Georgia: A study out of the University of Georgia sought to determine the level of host plant resistance that can be assured by several promising experimental bermudagrass genotypes against potential damages committed by the fall armyworm.
LAS VEGAS, NEVADA: Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere's water vapor. Without that input of water vapor, clouds could not form, and precipitation would never fall. It is the process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.
Studies on spintronics, which deal with the intrinsic spin of electrons and the field of electronic engineering, are actively conducted to address the limitation of integration level of silicon semiconductors currently in use and to develop ultra-low-power and high-performance next-generation semiconductors. Magnetic materials are one of the most commonly used materials to develop spintronics devices such as magneto-resistive random-access memory (MRAM).
Titled "Energy transition at the crossroads", the new issue of the Russian Journal of Economics gets a set of profound messages across, which can be summarized as: "transition matters, transition goes, yet transition is not a simple, unified march towards a Green future".
According to a new study from the University of Vaasa, Finland, seabed sediment and asphalt areas are noteworthy sources of heat energy also in northern conditions. Sediment heat has been studied in Suvilahti, Vaasa, and asphalt heat in the parking area of University of Vaasa for several years.
- I studied the usability of two new kinds of geothermal heat sources in Finnish conditions, says Mäkiranta, who is defending her doctoral dissertation on 18th December in the University of Vaasa.
WEST LAFAYETTE, Ind. -- Electronics are increasingly being paired with optical systems, such as when accessing the internet on an electronically run computer through fiber optic cables.
But meshing optics -- which relies on particles of light called photons--with electronics--relying on electrons -- is challenging, due to their disparate scales. Electrons work at a much smaller scale than light does. The mismatch between electronic systems and optical systems means that every time a signal converts from one to the other, inefficiency creeps into the system.
In extreme environments, even the most ordinary tasks can seem like unsurmountable challenges. Because of such difficulties, humanity has, for the most part, settled on grounds that were favorable for harvesting crops, herding cattle, and building shelters. But as we seek to expand the limits of human exploration, both on earth and in space, the people pioneering this search will undoubtedly face conditions that, for all intents and purposes, are not conducive to human habitation.
COLUMBUS, Ohio - Telling a distressed friend or family member something as simple as "I understand why you feel that way" can go a long way toward helping loved ones feel better, new research suggests.
In the study, participants described to the researchers a real-life incident that made them angry.
Many neurodegenerative conditions, from glaucoma to Alzheimer's disease, are characterized by injury to axons -- the long, slender projections that conduct electrical impulses from one nerve cell to another, facilitating cellular communications. Injury to axons often leads to neuronal impairment and cell death.
Electrons inhabit a strange and topsy-turvy world. These infinitesimally small particles have never ceased to amaze and mystify despite the more than a century that scientists have studied them. Now, in an even more amazing twist, physicists have discovered that, under certain conditions, interacting electrons can create what are called "topological quantum states." This finding, which was recently published in the journal Nature, has implications for many technological fields of study, especially information technology.
Researchers at HSE University and Lomonosov Moscow State University analyzed data on Russians' movements during the first wave of the COVID-19 pandemic. Their analysis showed that residents of lower-income municipalities self-isolated less compared to residents of higher-income cities. The findings were published in the journal Environment and Planning A.
The Fatty Acid Research Institute (FARI) has published a new research paper in conjunction with The Cooper Institute on omega-3s and heart rate recovery.
Omega-3 fatty acids have a long history of being "heart healthy" but exactly why and how has been less clear. They are known to lower serum triglyceride levels, but the effect is relatively small and it's not clear how much of a risk factor high triglyceride levels is in the first place. So how do the omega-3 fatty acids EPA and DHA work?
In 2006, Greenpeace launched a campaign exposing deforestation caused by soy production in the Brazilian Amazon. In the previous year, soy farming expanded into more than 1,600 square kilometers of recently cleared forests. The destruction, they said, had to stop.
In response, major soy companies in the region reached a landmark agreement as signatories to the Amazon Soy Moratorium (ASM), pledging not to purchase crops grown on recently cleared land. Deforestation fell in the following years, but no one had measured the moratorium's aggregate impact.
