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.

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.

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.
