  • The close-up shot above shows a cancer cell that has been cut open using an ion beam. The beam has blasted part of the cell away to reveal a cross section and has cut into the silica substrate, creating a triangular shape. Ion-beam milling allows researchers to look inside cancer cells in unprecedented detail. The image by biomedical engineer Nick Moser and cancer biologist Chris Bakal was shortlisted for the science- and medical-imaging competition run by the Institute of Cancer Research in London.

    • The Economic Impact of Massive Infectious and Contagious Diseases: The Case of Wuhan Coronavirus 18 Pages Posted: 3 Mar 2020 Mario Arturo Ruiz Estrada University of Malaya (UM) - Faculty of Economics & Administration (FEA) Donghyun Park Asian Development Bank - Economic Research Evangelos Koutronas West Virginia University - Department of Mathematics Alam Khan KUST Muhammad Tahir Comsats Institute of Information Technology Date Written: January 29, 2020 Abstract We evaluate the economic impact of the Wuhan coronavirus, a massive infectious and contagious disease, on China’s economic performance. To do so, we develop a new model, namely the Integral Massive Infections and Contagious Diseases Economic Simulator (IMICDE-Simulator) and apply it to the coronavirus outbreak. Our analysis based on the simulator indicates that the final impact will be substantial. The results indicate that the growth of the Chinese economy will decline from 6.2% in 2019 to 4.3% in 2020. Hence, the Chinese economy can lose easily a margin between 1.9% to 2% of its growth. The negative effect is significantly larger than that of SARS, and thus also likely to have larger spill-overs on other economies.

    • Diagnostic Testing for the Novel Coronavirus Joshua M. Sharfstein, MD1; Scott J. Becker, MS2; Michelle M. Mello, JD, PhD3 Author Affiliations Article Information JAMA. Published online March 9, 2020. doi:10.1001/jama.2020.3864 Controversies over diagnostic testing have dominated US headlines about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the novel coronavirus responsible for coronavirus disease 2019 (COVID-19). Technical challenges with the first test developed by the Centers for Disease Control and Prevention (CDC) left the nation with minimal diagnostic capacity during the first few weeks of the epidemic. The CDC also initially limited access to testing to a narrow group of individuals with known exposure. The delayed discovery of a case of COVID-19 in California, followed quickly by evidence of community transmission in multiple states, revealed the shortcomings of this strategy. In the early stages, COVID-19 has spread beyond the nation’s ability to detect it.
