DES PLAINES, IL -- Emergency physicians may benefit from training on safely handling firearms, according to the findings of a survey to be published in the March 2020 issue of Academic Emergency Medicine (AEM), a journal of the Society for Academic Emergency Medicine (SAEM).
Physicists have been trying to observe the quantum phenomenon Kondo cloud for many decades. An international research team has recently developed a novel device which successfully measures the length of the Kondo cloud and even allows for controlling the Kondo cloud. The findings can be regarded as a milestone in condensed matter physics, and may provide insights for understanding the multiple impurity systems, such as high-temperature superconductors.
CLAREMONT, CA (11 March 2020, 9 a.m. PDT)--The discovery of a small, bird-like skull, described in an article published in Nature, reveals a new species, Oculudentavis khaungraae, that could represent the smallest known Mesozoic dinosaur in the fossil record.
Researchers using ESO's Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.
A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors.
In a study published today in Nature, a team of engineers at UNSW Sydney has done what a celebrated scientist first suggested in 1961 was possible, but has eluded everyone since: controlling the nucleus of a single atom using only electric fields.
NORTH CAROLINA...March 11, 2020 - Despite a previous warning by Ben-Gurion University of the Negev (BGU) researchers, who exposed vulnerability in the 911 system due to distributed denial of service attacks (DDoS), the next generation of 911 systems that now accommodate text, images and video still have the same or more severe issues.
NASA-NOAA's Suomi NPP satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of newly formed Tropical Storm 21S.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of Tropical Cyclone 21S that revealed strong thunderstorms circling the center of circulation. Strong storms were also in the southeastern quadrant of the storm which extended to the coast of Western Australia.
HOUSTON - (March 11, 2020) - One bayou meanders toward downtown Houston. The other runs in parallel to the south, much of it through a concrete channel.
Which is better at preventing floods? Researchers at Rice University's Brown School of Engineering give the nod to nature.
Boston - In the United States, income inequality has steadily increased over the last several decades. Given widening inequities, health care leaders have been concerned about the health outcomes of older Americans who experience poverty, particularly because prior studies have shown a strong link between socioeconomic status and health.
The increase in diet-related illness has led to a high burden of costs for society. However, German policymakers, in comparison with their international counterparts, have so far been reluctant to make political interventions that support healthy eating habits among its citizens. The concern is that serious interventions, such as imposing taxes or even bans, will be unpopular. Researchers at the University of Göttingen have now shown, in fact, that there is clear support for nutritional policy action in Germany.

COVID-19: Protecting Hospitals from the Invisible

A German-American team of IT security researchers has investigated how users choose the PIN for their mobile phones and how they can be convinced to use a more secure number combination. They found that six-digit PINs actually provide little more security than four-digit ones. They also showed that the blacklist used by Apple to prevent particularly frequent PINs could be optimised and that it would make even greater sense to implement one on Android devices.
A University of Oklahoma-led study shows that grasshopper numbers have declined over 30% in a Kansas grassland preserve over the past two decades. Published in the Proceedings of the National Academy of Sciences (USA), the paper, "Nutrient dilution and climate cycles underlie declines in a dominant herbivore," reveals a new potent and potentially widespread threat to Earth's plant feeders: the dilution of nutrients like nitrogen, phosphorus, and sodium in the plants themselves due to increasing levels of atmospheric CO2.
Scientists at Washington University School of Medicine in St. Louis have developed a new imaging agent that could let doctors identify not only multiple types of tumors but the surrounding normal cells that the cancer takes over and uses as a shield to protect itself from attempts to destroy it.
The study appears March 9 in the journal Nature Biomedical Engineering.
Birds alighting on driveways and baby bunnies munching on lawn grass should keep something in mind: Beware the house cat.
A new study shows that hunting by house cats can have big effects on local animal populations because they kill more prey, in a given area, than similar-sized wild predators. This effect is mostly concentrated relatively close to a pet cat's home, since most of their movement was a 100-meter radius of their homes, usually encompassing a few of their neighborhood's yards on either side.
