Can airborne viruses survive in water?

Science Daily - Fri, 21/04/2017 - 1:15pm
A new study challenges the tenet that herpes viruses, like most enveloped viruses, are relatively unstable outside their host. Under a variety of conditions equine herpesvirus remained stable and infectious over a three week period. This suggests that untreated water could be a source of infection by some herpesviruses.

US Prepares Charges To Seek Arrest of WikiLeaks' Julian Assange

Slashdot - Fri, 21/04/2017 - 1:00pm
An anonymous reader quotes a report from CNN: U.S. authorities have prepared charges to seek the arrest of WikiLeaks founder Julian Assange, U.S. officials familiar with the matter tell CNN. The Justice Department investigation of Assange and WikiLeaks dates to at least 2010, when the site first gained wide attention for posting thousands of files stolen by the former U.S. Army intelligence analyst now known as Chelsea Manning. Prosecutors have struggled with whether the First Amendment precluded the prosecution of Assange, but now believe they have found a way to move forward. During President Barack Obama's administration, Attorney General Eric Holder and officials at the Justice Department determined it would be difficult to bring charges against Assange because WikiLeaks wasn't alone in publishing documents stolen by Manning. Several newspapers, including The New York Times, did as well. The investigation continued, but any possible charges were put on hold, according to U.S. officials involved in the process then.The U.S. view of WikiLeaks and Assange began to change after investigators found what they believe was proof that WikiLeaks played an active role in helping Edward Snowden, a former NSA analyst, disclose a massive cache of classified documents. Attorney General Jeff Sessions said at a news conference Thursday that Assange's arrest is a "priority." "We are going to step up our effort and already are stepping up our efforts on all leaks," he said. "This is a matter that's gone beyond anything I'm aware of. We have professionals that have been in the security business of the United States for many years that are shocked by the number of leaks and some of them are quite serious. So yes, it is a priority. We've already begun to step up our efforts and whenever a case can be made, we will seek to put some people in jail." Meanwhile, Assange's lawyer said they have "had no communication with the Department of Justice."
