ORLANDO, Oct. 30, 2020 - The increase in online education has allowed a new type of teacher to emerge ¬-- an artificial one. But just how accepting students are of an artificial instructor remains to be seen.
That's why researchers at the University of Central Florida's Nicholson School of Communication and Media are working to examine student perceptions of artificial intelligence-based teachers.
HOUSTON - (Oct. 30, 2020) - Let's call it the Texas two-step, but for molecules.
Rice University scientists have developed a method to reduce alkenes, molecules used to simplify synthesis, to more useful intermediates for drugs and other compounds via a dual-catalyst technique known as cooperative hydrogen atom transfer, or cHAT.
The process enables the hydrogenation of alkenes, hydrocarbons that contain a carbon-carbon double bond, in a simpler and more environmentally friendly way.
CHAPEL HILL, N.C.--Both cancer patients and their medical teams found it beneficial when patients shared their symptoms in real time using a web- or telephone-based reporting system, according to a national multi-institutional study.
Subarctic regions are facing rapid changes in climate and land-use intensity. An international research team recently completed an investigation to see how these changes are affecting the food webs and fish communities of lakes in northern Finland. Biomasses and omega-3 fatty acids, EPA and DHA, were determined from the algal producers at the base of food web to large carnivorous fish from 20 lakes along a pronounced climatic and productivity gradient. Increasing nutrient load and rising temperature shift food webs towards murky water adapted communities.
Researchers from the University of Kent, the Goethe-University in Frankfurt am Main (Germany), and the Hannover Medical School (Germany) have identified a drug with the potential to provide a treatment for COVID-19.
Optical barcodes enable detection and tracking via unique spectral fingerprints. They've been widely applied in areas ranging from multiplexed bioassays and cell tagging to anticounterfeiting and security. Yu-Cheng Chen of the Bio+Intelligent Photonics Laboratory at Nanyang Technological University notes that the concept of optical barcodes typically refers to a fixed spectral pattern corresponding to a single target.
Boston - While current antiretroviral treatments for HIV are highly effective, data has shown that people living with HIV appear to experience accelerated aging and have shorter lifespans - by up to five to 10 years - compared to people without HIV. These outcomes have been associated with chronic inflammation, which could lead to the earlier onset of age-associated diseases, such as atherosclerosis, cancers, or neurocognitive decline.
By studying impact marks on the surface of asteroid Bennu - the target of NASA's OSIRIS-REx mission - a team of researchers led by the University of Arizona has uncovered the asteroid's past and revealed that despite forming hundreds of millions of years ago, Bennu wandered into Earth's neighborhood only very recently.
Adoptively transferred T-cells can prolong survival and sometimes cure patients with advanced solid tumors. While promising, it can take months to generate the necessary T-cells to help these patients. Such slow speed makes this therapy impractical for most patients who need immediate treatment.
Cancer immunotherapies, which empower patients' immune systems to eliminate tumors, are revolutionizing cancer treatment. Many patients respond well to these treatments, sometimes experiencing long-lasting remissions. But some cancers remain difficult to treat with immunotherapy, and expanding the impact of the approach is a high priority.
Imperial College London researchers have simulated for the first time how soil moisture content affects the ignition and spread of smouldering peat fires, which can release up to 100 times more carbon into the atmosphere than flaming fires. They also simulated how several smaller peat fires can merge into one large blaze, and tracked the interplay between smouldering and flaming fires.
Researchers from Boston University, Rutgers University, University of Washington, Cornell University, and University of Pennsylvania published a new paper in the Journal of Marketing that proposes that preserving psychological ownership in the technology-driven evolution of consumption underway should be a priority for marketers and firm strategy.
The study, forthcoming in the the Journal of Marketing, is titled "Evolution of Consumption: A Psychological Ownership Framework" and is authored by Carey Morewedge, Ashwani Monga, Robert Palmatier, Suzanne Shu, and Deborah Small.
HANOVER, N.H. - October 29, 2020 - Researchers have designed a smart fabric that can detect non-metallic objects ranging from avocadoes to credit cards, according to a study from Dartmouth College and Microsoft Research.
The fabric, named Capacitivo, senses shifts in electrical charge to identify items of varying shapes and sizes.
Construction workers have a much higher risk of becoming hospitalized with the novel coronavirus than non-construction workers, according to a new study from researchers with The University of Texas at Austin COVID-19 Modeling Consortium.
Future pandemics will emerge more often, spread more rapidly, do more damage to the world economy and kill more people than COVID-19 unless there is a transformative change in the global approach to dealing with infectious diseases, warns a major new report on biodiversity and pandemics by 22 leading experts from around the world.
