A new study of researchers at IMT School for Advanced Studies Lucca, published in Scientific Reports, has identified tracks of increasing concern about pneumonia cases on posts published on Twitter in seven countries, between the end of 2019 and the beginning of 2020. The analysis of the posts shows that the whistleblowing came precisely from the geographical regions where the primary outbreaks later developed.

 E-Mail IMAGE: Optical flow field (blue arrows) when the drone flies straight forward. In the flight direction, the flow is smallest, making the tree in the drones path the hardest one to... view more  Credit: MAVLab/ TU Delft If you ever saw a honeybee hopping elegantly from flower to flower or avoiding you as you passed by, you may have wondered how such a tiny insect has such perfect navigation skills. These flying insects skills are partially explained by the concept of optical fl...

 E-Mail BROOKLYN, New York, Tuesday, January 19, 2021 - The World Health Organization reports that as of January 19, 2021, there are approximately 94 million cases of COVID-19 globally, with over 2 million deaths. In the face of these numbers -- driven in part by an aggressive resurgence of the virus in the U.S. -- health authorities face a tenuous balancing act: how to enact policies to keep citizens safe while doing the least possible damage to quality of life and local economies, especially...

Credit: (Image courtesy of Guy Theraulaz/Harvard SEAS) 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. The research is published in the Proceedings of the National Academy of Sciences. "Termite mounds are amongst the greatest examples of animal architecture o...

 E-Mail IMAGE: New research can help ecosystem managers identify species vulnerabilities and prevent populations from becoming at risk, like the endangered Mexican gray wolf. view more  Credit: U.S. Fish and Wildlife Service More than 3,000 animal species in the world today are considered endangered, with hundreds more categorized as vulnerable. Currently, ecologists dont have reliable tools to predict when a species may become at risk. A new paper published in Nature Ecology and Evo...

 E-Mail IMAGE: Using computer simulations built on reasonable assumptions and conducted under careful control, computational bioscientists can mimic real biological conditions. Starting with the original founding population (ancient phase), they can evolve... view more  Credit: © 2021 KAUST; Anastasia Serin Computer simulations of cells evolving over tens of thousands of generations reveal why some organisms retain a disused switch mechanism that turns on under severe stress, changin...
