University of British Columbia researchers have found a new system that could help yield 'warmer' quantum technologies.
Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.
University of Houston researchers link autism spectrum disorders to defects in a nuclear receptor inside the brain. And just like that, this world-renown team advances the understanding of autism.
When a thin purple ribbon of light appeared and starting glowing in the midnight sky over Regina, Canada, in 2016, Notanee Bourassa knew that what he was seeing was not normal. Having watched the northern lights for almost 30 years, he knew this wasn't an aurora. It was something else.
Last year, 81 million people worldwide experienced severe food insecurity. About 80 percent of them live in Africa.While much of that food insecurity relates to civil war and violence in places like South Sudan and Nigeria, a good portion also stems from a sequence of five severe droughts that began in Ethiopia in 2015 and spread across parts of the continent in the ensuing three years.
Nuclear fusion, the process that powers our sun, happens when nuclear reactions between light elements produce heavier ones. It's also happening -- at a smaller scale -- in a Colorado State University laboratory.Using a compact but powerful laser to heat arrays of ordered nanowires, CSU scientists and collaborators have demonstrated micro-scale nuclear fusion in the lab. They have achieved record-setting efficiency for the generation of neutrons - chargeless sub-atomic particles resulting from the fusion process.
Researchers at the University of Pennsylvania set out to determine whether and how gum-derived stem cells play a role in accelerated wound healing. Their results, indicating that these cells secrete tiny vesicles packed with signaling proteins, point the way forward for therapeutic strategies that aim to harness the prowess of stem cells to treat delayed wound healing as well as other conditions that involve an overactive inflammatory response, such as autoimmune diseases.
An international team led by researchers from the Spanish National Research Council (CSIC) has developed a method to measure the integration or segregation of immigrants based on the messages they write on the social network, Twitter.
For the first time, researchers have produced a nearly complete three-dimensional structure for the yeast Nuclear Pore Complex (NPC). This discovery represents a major step toward identifying the atomic structure of the NPC, which soon may provide researchers with a better understanding of how the central transport channel functions.
A team of researchers have developed an open-source, clinically validated template for a 3-D printed stethoscope for use in areas of the world with limited access to medical supplies -- places where a stethoscope could mean the difference between life and death.
Scientists at The Australian National University (ANU) are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of tectonic plates, which regulate the water cycle that is critical for a habitable planet.
A team led by scientists from Scripps Institution of Oceanography at the University of California San Diego and the J. Craig Venter Institute (JCVI) has demonstrated that the excess carbon dioxide added to the atmosphere through the combustion of fossil fuels interferes with the health of phytoplankton which form the base of marine food webs.
Researchers have produced a 'human scale' demonstration of a new phase of matter called quadrupole topological insulators that was recently predicted using theoretical physics. These are the first experimental findings to validate this theory.
Researchers at VIB and KU Leuven have uncovered a trio of complementary ion channels in sensory neurons that mediate detection of acute, harmful heat. Having three redundant molecular heat-sensing mechanisms provides a powerful fail-safe mechanism that protects against burn injuries. The seminal findings have been published today in Nature.
Both cell type and developmental stage can be deduced from measurements of chromatin accessibility in thousands of single cells, researchers at EMBL and the University of Washington show. They used this approach to uncover how cells in developing embryos regulate their identity as they decide what kind of cell to become. Nature publishes the results on March 14.
MIT and Australian scientists have found that seismic imaging is blind to water, a finding that may lead researchers to reinterpret seismic maps of the Earth's interior.
Ocean acidification will severely impair coral reef growth before the end of the century if carbon dioxide emissions continue unchecked. The paper represents the first ocean acidification experiment in which seawater was made artificially acidic by the addition of carbon dioxide and then allowed to flow across a natural coral reef community. The acidity of the seawater was increased to reflect end-of-century projections if carbon dioxide from greenhouse gas emissions are not abated.
Eric Skaar, Ph.D., M.P.H., and colleagues at Vanderbilt have combined multiple types of molecular imaging to probe an invasive Staphylococcus aureus infection in the mouse. Their integrated imaging approach, reported this week in Science Translational Medicine, revealed new insights about staph infections and can be broadly applied to any health or disease state.
The extreme wet and dry periods Mongolia has experienced in the late 20th and early 21st centuries are rare but not unprecedented and future droughts may be no worse. An international team of researchers developed a climate record stretching 2,060 years into Mongolia's past using tree rings. The team then combined the tree-ring record of past climate with computer models that can project future regional climate.
Sexual minority students -- lesbian, gay, bisexual and queer -- were less likely than their heterosexual peers to be retained in STEM degrees after four years of college, suggests a new study based on a national survey of more than 4,000 college students. Diversity is crucial in STEM fields, providing a greater likelihood of reaching breakthroughs. However, compared.
