Even if all nuclear power plants were shut down today, there’s a mountain of radioactive waste waiting to be disposed of. Yet only Finland has an approved solution for nuclear waste disposal, while projects in the US , UK , and Germany have failed for decades, and progress is also slow in other countries . With growing calls to extend the life of existing nuclear power stations and build new ones, that mountain of radioactive waste sitting in temporary , vulnerable , and expensive storage will keep growing. The challenge is daunting. “ High-level ” nuclear waste, which includes spent nuclear fuel, stays radioactive for hundreds of millennia , so a waste facility must keep it safely away from aquifers, violent weather, war, plane crashes, sea level rise, future ice sheets, volcanic activity, and even curious future humans for a time span that dwarfs all of previous human history. Ultimately, it’s the geology of a proposed disposal site that determines if … [Read more...] about Solving the rock-hard problem of nuclear waste disposal

A security researcher says that Apple's iOS devices don't fully route all network traffic through VPNs as a user might expect, a potential security issue the device maker has known about for years. Michael Horowitz, a longtime computer security blogger and researcher, puts it plainly—if contentiously—in a continually updated blog post . "VPNs on iOS are broken," he says. Any third-party VPN seems to work at first, giving the device a new IP address, DNS servers, and a tunnel for new traffic, Horowitz writes. But sessions and connections established before a VPN is activated do not terminate and, in Horowitz's findings with advanced router logging, can still send data outside the VPN tunnel while it's active. In other words, you might expect a VPN client to kill existing connections before establishing a secure connection so they can be re-established inside the tunnel. But iOS VPNs can't seem to do this, Horowitz says, a finding that is backed up by a similar report from May … [Read more...] about iOS VPNs have leaked traffic for more than 2 years, researcher claims
