 E-Mail IMAGE: Physicists have developed a new method that enables emulation of complex calculations at lightning speed. This could yield new insights about the quantum properties of strongly interacting matter such as... view more  Credit: Illustration: Andreas Ekström and Yen Strandqvist/Chalmers University of Technology A calculation so complex that it takes twenty years to complete on a powerful desktop computer can now be done in one hour on a regular laptop. Physicist Andreas Ekström at Chalmers University of Technology, together with international research colleagues, has des...

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.

These flying insects' skills are partially explained by the concept of optical flow: they perceive the speed with which objects move through their field of view. Robotics research...

 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 in smaller cities and towns, where short supply of intensive care units and tight budgets make the ...
