Gas Sensors Sound the Smoldering Fire Alarm

Sep. 3, 2015 — Smoke detectors are everywhere, but still thousands of people die in fires annually. Fire gas detectors, which detect carbon monoxide and nitrogen oxide, identify fires at an early stage. Thanks to a ... read more

Aug. 28, 2015 — Even large objects obey quantum physics, meaning they are never quite at rest. Researchers have developed a way to detect -- and manipulate -- this underlying quantum ... read more

Aug. 28, 2015 — With detection limits down to the zeptomolar range (about 600 molecules in a sample), a new technology can analyze the metabolic composition of individual microbial cells, as well as detect the ... read more

Neurobiology: Light-Activated Learning

Aug. 28, 2015 — Scientists have developed a light-sensitive switch that regulates a protein implicated in the neurobiology of synaptic plasticity. The agent promises to shed new light on the phenomenology of ... read more

Cheaper, Better LED Technology
