in a new study published in The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and areas of abundant ionised particles in the hot outer atmosphere.
Modern decision theory can assist policymakers in critical times such as the COVID-19 crisis, argue Bocconi University's Massimo Marinacci and Valentina Bosetti in a paper coauthored by Nobel laureate Lars Peter Hansen
Researchers at the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) in Argentina have found that, since the 1990s, up to 25% of reported bee species are no longer being reported in global records, despite a large increase in the number of records available. While this does not mean that these species are all extinct, it might indicate that these species have become rare enough that no one is observing them in nature. The findings appear January 22 in the journal One Earth.
A new global, mathematical modeling study pubilshed in the journal Science shows that in most cases prioritizing older adults for COVID-19 vaccines saves the most lives. It also found that, in some cases, more lives could be saved and infections prevented if those who've already tested positive step to the back of the line.
To help build aircraft that can better handle violent turbulence, Purdue University researchers developed a new model that allows engineers to incorporate the physics of an entire vortex collision into their design codes.
While autonomous drones can greatly assist with difficult rescue missions, they require a safe landing procedure. In a new study, scientists from Shibaura Institute of Technology (SIT), Japan, have demonstrated automated drone landing with a simple 2D camera guiding the drone to a symbolized landing pad. The guiding camera can be further improved to include depth-related information, paving the way for novel applications in indoor transportation and inspection.
Researchers say they have been able to greatly improve the readout of data from digital memories - thanks to a phenomenon known as 'quantum entanglement'.
An international research team has developed a fast and affordable quantum random number generator. The device created by scientists from NUST MISIS, Russian Quantum Center, University of Oxford, Goldsmiths, University of London and Freie Universität Berlin produces randomness at a rate of 8.05 gigabits per second, which makes it the fastest random number generator of its kind. The study has been published in Physical Review X.
A mathematical framework enables accurate characterization of shapes
Following a series of studies on termite mound physiology and morphogenesis over the past decade, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have now developed a mathematical model to help explain how termites construct their intricate mounds.
