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.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
