America leads the world in adult science literacy, science output and social media. That means broad social networks.

And it means, unless some field of science is your particular hot-button issue, the US is doing better in science acceptance than every other country, and spending time and money doing awareness is not really helping much.

Facial recognition software works pretty well. It measures various parameters, such as the distance between the person's eyes, the height from lip to top of their nose and various other metrics and then compares it with photos of people in a database.

Why not create emotion recognition software that can use its own custom parameters? 

Dev Drume Agrawal, Shiv Ram Dubey and Anand Singh Jalal of the GLA University, in Mathura suggest in the International Journal of Computational Vision and Robotics
has taken a three-phase approach to a software emotion detector.

A team of researchers has developed a new model to study the motion patterns of bacteria in real time and to determine how these motions relate to communication within a bacterial colony.

The researchers chemically attached colonies of Escherichia coli bacteria to a microcantilever – a microscopic beam anchored at one end, similar to a diving board – thus coupling its motion to that of the bacteria. As the cantilever itself isn't doesn't generate any vibrations, or 'noise,' this allowed the researchers to monitor the colony's reactions to various stimuli in real time.

For lovers of wild foods, autumn means things like mushrooms and fungi of dizzying variety.

Intrepid treasure hunters scour the woods in search of delectable wild mushrooms and their not-quite-meat, not-quite-vegetable qualities.

A bonus: If you find some, you may be eating something not even known to science.

The Fungi Kingdom is enormously diverse and completely under-documented. Species are tough to know, and that is without counting the billions that have gone extinct without us ever knowing about them, but of the 10 million species likely out there, only about 100,000 have been described.

That DNA makes RNA which makes protein is a simplified explanation molecular biologists use to explain for how genetic information is deciphered and translated in living organisms.

The process is more complicated than the schema first articulated nearly 60 years ago by Nobel Laureate Francis Crick, co-discoverer of the DNA's double-helix structure. Now it is known that there are multiple types of RNA, three of which—messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA)—are essential for proper protein production. Moreover, RNAs that are synthesized during the process known as transcription often undergo subsequent changes, which are referred to as "post-transcriptional modifications."

If we get sugars down to 3% of total energy intake, it may put dentists out of business, according to a paper in BMC Public Health which analyzed the effect of sugars on tooth decay and found that sugars are the only cause of tooth decay in children and adults.

Free sugars are defined by the World Health Organisation Nutrition Guidance Advisory Group as "Free sugars include monosaccharides and disaccharides added to foods by the manufacturer, cook or consumer, and sugars naturally present in honey, syrups, fruit juices and fruit concentrates."
