WASHINGTON — The Secure World Foundation on April 2 released its annual report, “Global Counterspace Capabilities: An Open Source Assessment,” that sheds light on the growing space arms race between the United States, Russia and China. The report, compiled from publicly available information, details the counterspace capabilities — essentially space weapons — being developed by

Solution with the hepatocytes (liver cells) in suspension LyGenesis For the first time, a person has received an experimental treatment to transform one of their lymph nodes into a functioning miniature liver. We won’t know for months whether the therapy works, but if it does, it could revolutionise the treatment of liver disease. “This is
