Nest recalling 440K smoke alarms for safety risk
Government regulators on Wednesday said that they have approved Nest Labs' plans to fix a feature in its smoke alarms that could prevent them from sounding immediately.
Improving terahertz optics with efficient broadband antireflection coatings
Antireflection coatings are familiar from their use in everyday optical devices, such as glasses and lenses. They can increase the amount of light that passes through optical instruments by reducing the fraction ...
Inspecting letters with terahertz waves
Is it a harmless parcel or a bomb, an innocent letter or a drug shipment? A new terahertz scanner is capable of detecting illicit drugs and explosives sent by post without having to open suspicious packages ...
Will the 2014 El Nino be like 1997?
Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet ...
Engineers invent a way to beam power to medical chips deep inside the body
A Stanford electrical engineer has invented a way to wirelessly transfer power deep inside the body, and then use this power to run tiny electronic medical devices such as pacemakers, nerve stimulators, or ...
New 'T-ray' tech converts light to sound for weapons detection, medical imaging
A device that essentially listens for light waves could help open up the last frontier of the electromagnetic spectrum—the terahertz range.
Tricking the uncertainty principle

Blogger claims BICEP2 team acknowledging possible error in discovery of evidence of gravitational waves
Dancing beads on surface waves cluster in surprising ways
(Phys.org) —FOM researchers have discovered that objects floating on surface waves behave differently than expected. If a small number of floating objects is present on a water surface, these will drift ...
