Researchers build miniature flying robots, modeled on Drosophila
“We may not be at fruit fly level yet, but researchers are giving the insects some competition. In today’s issue of Science, they report on miniature flying robots that aren’t much bigger than a coin. The power and control are handled externally, but the tiny robots can still perform basic maneuvers, and have enough lift to spare that they could fly under their own power for a few minutes, if the right power storage were developed.”
Born in 1707, Carl Linnaeus would rise to such a level of greatness that the philosopher Jean-Jaques Rousseau once said “Tell him I know no greater man on earth,” and was heralded by many of his contemporaries and apostles as Princeps botanicorum - the Prince of Botany. This praise was not without merit: he’s the reason we name almost everything in biology the way that we do. Prior to Linnaeus, the science dealing with naming, organizing, and classifying organisms, called taxonomy, was a disorganized and confusingly complex mess. The word taxonomy is derived from an irregularly-conjugated Ancient Greek word taxis which means arrangement, and the Ancient Greek suffix -nomia, derived from the Ancient Greek word nemein, meaning to manage.
Linnaeus had a passion for botany, and while he went to school to study medicine, his long-term goals always included learning about plants. At 25, he won a grant to travel to Lapland and document the local flora and fauna. While there, he began to classify the flowers he found with what we now know as the bionomial classification system - from the Latin bi, meaning two, and nominus meaning name. Prior to this system, species were given long, many-worded descriptive names, and there were several competing outlines for classifying plants and animals into groups, none of which were particularly accurate or helpful to a scientist not intimate with the specific branch of biology the outline was designed for.
The binomial classification system uses two identifiers for a species - the “generic name” (also known as its genus), and the “specific” name (also known as the species). Linnaeus introduced this system in his book Systema naturae, first published in 1735. Even though the first edition was basic and just twelve pages long, it introduced to the scientific community a system that was simple, understandable, easy to remember, and easy to add new species to. Throughout his life, Linnaeus and his apostles continued work on Systema naturae, and by its 10th Edition in 1758, it classified over 4400 species of animals, and 7700 species of plants.

To everyone asking: “Pangolin = sandshrew?”
Baby Pangolin or 9-Ringed Armadillo x Shrew = Sandshrew.
Pangolin = SandSLASH.
