Studying genetic variation in the common brown lizard, Anolis sagrei, the researchers found that introduced populations of the lizard in five different countries can be traced back to the Sunshine State as their site of export.
The team analyzed a small region of DNA from more than 600 different individuals to get a genetic "ID card" for each lizard. The historic home for Anolis sagrei is the Caribbean, especially Cuba, where the researchers have found that there are at least eight genetically distinct groups of the lizard. In the late 1800s, Anolis sagrei was introduced (probably through a shipment of goods) to the Florida Keys, got a toehold and, after a decades-long lag, began spreading into the Florida mainland in the 1940s, most likely from separate introductions.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
