UrduAt the beginning of the COVID-19 pandemic, Joachim Kock, mathematician at the Universitat Autònoma de Barcelona (UAB), began to experiment with epidemiological models. He did not improve upon the predictions, but unexpectedly he made a mathematical discovery that led to the solution of an old problem in theoretical computer science, open since the 1980s, on Petri nets.

Research to improve space weather predictions by Dr. Nikolai Pogorelov at The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, will boost abilities crucial to the success of the defense mission of the Space Force Command that’s set to be located in Huntsville, Ala.
In New Step Towards Autonomous Materials, Researchers Design Patterns in Self-propelling Liquid Crystals
Imagine a capsule implanted in your body that automatically releases antibodies in response to a virus, or clothing that senses and captures contaminants from the air.
PME researchers have taken a step toward developing such autonomous materials by creating self-propelling liquid crystals and patterning their activity to control the movements of defects within the crystals.
UAH solar physicist proposes new mechanism for how electrons work in solar flares
A new mechanism to explain how electrons work in solar flares has been proposed by a University of Alabama in Huntsville (UAH) solar physicist using a theoretical model of particle acceleration.
Los Alamos study hopes to characterize and optimize ventilator treatment for Covid-19
Cross-disciplinary scientists and engineers at Los Alamos National Laboratory are working to learn how Intrapulmonary Percussive Ventilation (IPV) helps clear mucus from blocking the airways of the human lung, a common reaction to the Covid-19 virus.
Issei Nakamura Wins CAREER Award for Charged Liquids Research
Michigan Tech physicist Issei Nakamura has received a National Science Foundation (NSF) CAREER Award for his research on computational methods to simulate how polymeric liquids interact with electric charges.
Computer-based Modeling Identifies how Cell Death Is Regulated in Ischemic Kidney Injury

U wildfire researchers fine-tune forest fire computer models
Grass fires behave differently than those in forests. But computer fire simulations don’t capture that difference very well. Derek Mallia and colleagues found that conventional models overestimate the growth rate of fires in forests and the height of smoke plumes.…
Scientists look to space to track plant pathogens coasting through atmosphere
To better understand how plant pathogens that travel the globe with dust particles might put crops at risk, a Cornell University-led team of scientists will use data from NASA’s Earth Observing Satellites to identify areas of potential disease and track plumes of dust that traverse the globe.
Social distancing and COVID-19: A law of diminishing returns
Modeling from the McKelvey School of Engineering at Washington University in St. Louis shows how social distancing could have better been implemented. The key? Longer periods of distancing would have helped — but only to a point. More needed to be done.
Iowa State University joins the international APSIM Initiative
The Iowa State University Department of Agronomy is the first North American entity to join the Agricultural Production Systems sIMulator (APSIM) Initiative. The computer modeling tools predict crop production in light of climate, genotype, soil and management factors.
