A new portable sensor system detects airborne organic chemicals about as accurately as a $25,000 machine confined to a lab. The device’s sensor element (above) holds an array of polymers deposited between capacitance plates; their ability to store electrical charge changes in specific ways when certain molecules are absorbed, enabling the device to identify those agents. The system incorporates a polymer called BSP3, invented at Pacific Northwest National Laboratory, that is especially responsive to compounds such as nerve agents and certain pesticides.

A new study shows what it might take to make AI useful in health care
Researchers used machine vision to help nurses monitor ICU patients. The way they approached their work shows the value of asking what people actually need artificial intelligence for.
Trained neural nets perform much like humans on classic psychological tests
Neural networks were inspired by the human brain. Now AI researchers have shown that they perceive the world in similar ways.
No, scientists didn’t just “reverse time” with a quantum computer
Amazing headlines about time machines are a long way off the mark, sadly.
