Matsumoto was also the first to publish scientific evidence that microexpressions may be a key to detecting deception. [38] Despite the prevailing belief among law enforcement and the public that micro-expressions are able to reveal whether a person is being deceitful, [39] there is a lack of empirical evidence to support this claim.
In The Expression of the Emotions in Man and Animals published in 1872, Charles Darwin theorized that emotions were evolved traits universal to the human species. However, the prevalent belief during the 1950s, particularly among anthropologists , was that facial expressions and their meanings were determined through behavioral learning processes.
Both Matsumoto [7] and Ekman [8] now have their own versions of the microexpression training tool, which is available on their websites. In 2009, Matsumoto and Bob Willingham conducted a study examining spontaneous facial expressions in blind judo athletes. They discovered that many facial expressions are innate and not visually learned. [9]
Leakage occurs when nonverbal signals betray the true content of a contradictory verbal message. Facial expression is difficult to read, and the Facial Action Coding System (FACS) is a means of uncovering deception. Small facial movements, known as micro-expressions, can be detected in this system using action units.
It is often stated as "DNA makes RNA, and RNA makes protein", [1] although this is not its original meaning. It was first stated by Francis Crick in 1957, [2] [3] then published in 1958: [4] [5] The Central Dogma. This states that once "information" has passed into protein it cannot get out again.
How to use a microarray for genotyping. The video shows the process of extracting genotypes from a human spit sample using microarrays. Genotyping is a major use of DNA microarrays, but with some modifications they can also be used for other purposes such as measurement of gene expression and epigenetic markers.

The development of FACS tools for different species allows the objective and anatomical study of facial expressions in communicative and emotional contexts. Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21]
