New Rochelle, NY, April 20, 2020--A new study analyzing tweets about COVID-19 found that users with larger social networks tend to use fewer uncivil remarks when they have more positive responses from others. The study, which used computer-assisted content analysis, is published in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
To find out more about birds such as the black-tailed godwit, ecologists have been conducting long-term population studies using standardized information on reproductive behaviour--such as dates of egg-laying or hatching and levels of chick survival. New information gathered using geolocators on godwits in the Netherlands shows that traditional observation methods can lead to inaccurate data. The study was published in the April-issue of the Journal of Avian Biology.
New Rochelle, NY, April 20, 2020--A group of researchers with experience in treating high altitude pulmonary edema (HAPE) have written to correct the misconception in medical social media forums and elsewhere that the lung injury seen in COVID-19 is not like typical acute respiratory distress syndrome (ARDS) and is instead like HAPE.
When people suffer debilitating injuries or illnesses of the nervous system, they sometimes lose the ability to perform tasks normally taken for granted, such as walking, playing music or driving a car. They can imagine doing something, but the injury might block that action from occurring.
Brain-computer interface systems exist that can translate brain signals into a desired action to regain some function, but they can be a burden to use because they don't always operate smoothly and need readjustment to complete even simple tasks.
Now you see it, now you don't.
What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight. Though this happens in science fiction, such as Superman's home planet Krypton exploding, astronomers are looking for a plausible explanation.
What astronomers thought was a planet beyond our solar system, has now seemingly vanished from sight. Astronomers now suggest that a full-grown planet never existed in the first place. The NASA/ESA Hubble Space Telescope had instead observed an expanding cloud of very fine dust particles caused by a titanic collision between two icy asteroid-sized bodies orbiting the bright star Fomalhaut, about 25 light-years from Earth.
DURHAM, N.C. -- As droughts become more frequent and intense, the fragmentation of water service in the U.S. among tens of thousands of community systems, most of which are small and rely on local funding, leaves many households vulnerable to water contamination or loss of service, a new Duke University analysis finds.
These vulnerabilities aren't distributed equally, the study shows. Households in low-income or predominantly minority neighborhoods are likely to face the highest risks.
INDIANAPOLIS -- Putting together research for publication can be a challenging and time-consuming process, heightened even further because of the current COVID-19 situation, during which non-essential labs have been hibernated and many researchers are now working separately and remotely, instead of collaborating within the same space.
In the latest issue of Molecular Therapy, Skoltech and MIT researchers have published a new combinatorial therapy for the treatment of liver cancer. Using a siRNA approach, a field in which Dr Zatsepin (Skoltech) excels, coupled with lipid nanoparticle technology developed in the Anderson laboratory (MIT), the scientists targeted proteins that are involved in apoptosis, a regulated program for cell death. In combination with chemotherapy, this caused a significant decrease in tumor load in a mouse model of hepatocellular carcinoma.
Your phone's GPS, the WiFi in your house and communications on aircraft are all powered by radio-frequency waves, or RF waves, which carry information from a transmitter at one point to a sensor at another. The sensors interpret this information in different ways. For example, a GPS sensor determines its location by using the amount of time it takes to receive a signal from a satellite. For applications such as in-door localization and defeating spoofing GPS signals, a wireless sensor measures the angle at which it receives an RF wave.
