A "3D" processor could make wireless communication more efficient according to scientists at the University of Florida. It could benefit both WiFi and cellular data services. One of the limitations of current WiFi tech is that it uses a "planar ... processor" to handle the wireless signal. Because these processors are (in practical terms) two-dimensional, they can only work with a limited range of wireless frequencies. Expanding the range of frequencies planar processors can handle is only possible by making them wider, a little like increasing capacity on roads. But making the ... (view more)

Android devices may soon tell users when their phone is starting to degrade. It's a feature already found in phones. The feature is not about the percentage of charge the battery has, which is easy to find in Android settings and can be shown ... permanently on the screen. Instead, it's about battery health. It's described by Google as the "estimated percentage of charge the battery can currently hold compared to when it was new." That's not necessarily as straightforward as it might seem: battery life doesn't necessarily degrade at a consistent rate. A rule of thumb, the battery should retain at ... (view more)

Walmart has stopped offering a 30TB portable hard drive that was listed on its website for $39. The third-party listing was not an unbelievable bargain but rather an audaciously cheeky scam.

Those familiar with the SSD market would recognize straight away that this was, to say the least, an implausible price. Most externals SSD ranges designed for the consumer market top out at 4TB ... (view more)
