However, while the first gene therapy products approved by the Federal Drug Ad...

 E-Mail Researchers from North Carolina State University used a three-model approach to trace the between-farm spread of porcine epidemic diarrhea virus (PEDV), as well as to analyze the efficacy of different control strategies in these scenarios. The approach may enable farmers to be more proactive in preventing the spread of PEDV and to optimize their efforts to control the disease. PEDV is a virus that causes high mortality rates in preweaned piglets. The virus emerged in the U.S. in 2013 and by 2014 had infected approximately 50 percent of breeding herds. PEDV is transmitted by contact w...

 E-Mail Wilmington, DE, Feb. 11, 2020 -Scientists have developed an affordable, downloadable app that scans for potential unintended mistakes when CRISPR is used to repair mutations that cause disease. The app reveals potentially risky DNA alterations that could impede efforts to safely use CRISPR to correct mutations in conditions like sickle cell disease and cystic fibrosis. The development of the new tool, called DECODR (which stands for Deconvolution of Complex DNA Repair), was reported today in The CRISPR Journal by researchers from ChristianaCare's Gene Editing Institute.   "Our rese...

Credit: Peter the Great St.Petersburg Polytechnic University The energy of the future lies in the area of the controlled thermonuclear fusion. The scientific group from Peter the Great St.Petersburg Polytechnic University (SPbPU), headed by Professor Vladimir Rozhansky, is directly involved in the establishment of the world's largest experimental thermonuclear reactor ITER. Researchers discovered new effects, which affect the energy flow in the reactor. The theoretical predictions were confirmed by the experiments on two tokamaks. The research results were published in the scientific jo...

The academic field of network science is concerned with analyzing such real-world complex networks and understanding how their structure influences their function or behavior. Examples ...
