Emotion detector: Facial expression recognition to improve learning, gaming Posted: 27 Apr 2016 07:36 AM PDT A computer algorithm that can tell whether you are happy or sad, angry or expressing almost any other emotion would be a boon to the games industry. New research describes such a system that is almost 99 percent accurate.

A single-celled organism capable of learning Posted: 27 Apr 2016 05:15 AM PDT For the first time, scientists have demonstrated that an organism devoid of a nervous system is capable of learning. Biologists have succeeded in showing that a single-celled organism, the protist, is capable of a type of learning called habituation. This discovery throws light on the origins of learning ability during evolution, even before the appearance of a nervous system and brain. It may also raise questions as to the learning capacities of other extremely simple organisms such as viruses and bacteria.

Chemists use DNA to build the world's tiniest thermometer Posted: 27 Apr 2016 05:07 AM PDT Researchers have created a programmable DNA thermometer that is 20,000x smaller than a human hair. One of the main advantages of using DNA to engineer molecular thermometers is that DNA chemistry is relatively simple and programmable. So, the research team has created various DNA structures that can fold and unfold at specifically defined temperatures.
