Google has just unveiled Project Tango, a smartphone with built-in 3D computer vision technology. Think of it as a smartphone with built-in Kinect functionality — but rather than enable Leap-like gesture control, the computer vision tech is used to create a full 3D map of your current environment. At its most basic, you might use Tango to create a map of your house, or a 3D model of your favorite antique vase or your motorbike.

Researchers working at a lab at Harvard University have developed a technique that allows for taking the temperature of individual living cells. In their paper published in the journal Nature, the team describes their technique and just how precise temperature measurements taken with it can be.

Quantum coherence in diamond and fluorescence thermometry

Thermometry – the measurement of temperature – is critical to a wide range of applications, including many industrial processes, biomedical monitoring, and environmental regulatory systems. However, measuring temperature in the presence of high RF (radio frequency) or other electromagnetic fields – such as are found in aerospace, automotive and medical systems – cannot be accomplished using electrical thermometric probes.
