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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
