Scientist 3D printed a Star Trek USS Voyager spaceship that is smaller than the width of a human hair.

Scientists at Leiden University in the Netherlands have created a 3D-printed version of Star Trek's USS Voyager spaceship that measures a ultra-tiny 15 um (micrometers) long. By comparison, the width of a human hair is 50 um. The USS Voyager spaceship is so tiny, it can only be viewed through a microscope! Microswimmers Scientists create microscopic models so they can study "microswimmers". Microswimmers are important because they will one day lead to tiny swimming robots that can be turned loose in the human body to repair tiny injuries or deliver drugs to a precise location inside the body. Because they are so tiny, microswimmers face a variety of challenges that scientists must solve. For instance, their small size and shape means they are impacted by the fluid's viscosity

See the intercontinental path of two birds on their epic migration from Europe to Africa

The guys over at 422 South have done it again providing us a wonderful “data-visualization” of the migratory path of the European honey buzzard.  The European honey buzzard, also known as the pern, migrates every year from Europe to the warmer coasts of Africa where it spends the winter months soaking in the warm sun and sipping on drinks with little umbrellas in them.  The visual above shows the remarkable flight paths of two such honey buzzards, a male and a female, between Fall 2010 and Spring 2011.  Both birds' southward migration took them from the Veluwe forest in the Netherlands to the warmer weather on the African coast (Liberia, Ghana, and Cameroon).  After wintering in Africa, both birds flew back to the Veluwe forest (the
