Unparalleled investigation leads to looters’ haven and arrests
An unprecedented collaboration of archeologists, Maya villagers and Guatemalan authorities has resulted in the recovery of a magnificent Maya altar stone that was carved in 796 AD and sheds new light on the collapse of the classic Maya civilization. In addition to the altars archeological importance, its recovery illustrates the value of working with indigenous peoples to restore ancient ruins. Archaeologist Arthur Demarest of Vanderbilt University, who helped recover the altar from the looters hideout, said the relic is one of the finest Maya altars known and provides important clues about one of the wealthiest Maya kingdoms.
The great altar was placed in 796 A.D. as a marker at the end of the royal ball court of Cancuén, the site of one of the largest royal palaces ever found, where the ancient citys ruler would play the sacred Maya ball game against visiting kings. The role of the game was more ritual than sport. Location of ball courts in the ritual space within Maya cities, and the imagery that accompanies them, underscores their role as boundaries between the actual and supernatural worlds.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
