Researchers from Indiana University (IU) have made the first direct visual observation of bacteria taking up foreign DNA from its surrounding. It is a key step in their process of rapidly evolving new traits, including troublesome drug resistance. The new methods developed by the researchers provided them with the ability to catch this mechanism on film.
Isn´t the sensation of being tickled just the most bizarre? As silly as it might seem, there is apparently a whole evolutionary war being waged in the process of tickling, according to studies.
One of the particularly interesting chemical properties that are giving us some insight into our organic world is chirality. Chirality is a geometric property of most biochemical molecules that makes them different than their mirror images, just like our left and right hand are.
