Is this an impostor trying to break into your phone with his voice?
You can log in to your smartphone by talking to it. Current security systems don't protect enough against imitators. The best way to ensure voice authentication is secure is to start with the sound.

Citizens and activists are using cheap off-the-shelf sensors to collect their own data on air pollution. It's a promising trend, but these devices have serious technical limitations.
Connecting cities should serve all citizens, not just a few.

Design will make the difference between smart city projects offering great promise or actually reinforcing or even widening the existing gaps in unequal ways their cities serve residents.
A hydro-responsive thread can be used with sensors to monitor body functions.

Flexible, easy to make, inexpensive, stretchable and simple to coat with nanomaterials, threads are also very commonly used by doctors already.
Microsoft Kinect's cheap sensors could create low-cost 3D computer models of crime scenes.
Humidity levels can mean life or death for insects.
Detecting drier or wetter conditions is crucial for insect survival. We've long known they can do this – now researchers have discovered the genetic and neural basis for their humidity-sensing system.
These backpacked pigeons are patrolling London’s skies.

This low-cost way of monitoring air quality is appealing, but there needs to be acknowledgement of their weaknesses as well as strengths.
Still a few kinks to be worked out.
We can already track plenty of body data, but to really make a difference, wearables need to consistently collect clinically valuable information that can be used to improve health.
Tractors may have revolutionised farming but to protect biosecurity, farmers could do with some extra help.
