Scientists have performed successful teleportation on atoms for the first time, the journal Nature reports.

Teleportation breakthrough made

''Waste heat'' might not be such a waste after all. The excess heat produced in everything from microelectronics to large ship engines is generally thought of as a problem for engineers to solve. But a new leap in semiconductor technology funded by the Office of Naval Research could put that troublesome heat to good use.

Archaeologists have found what they believe to be the site of the Library of Alexandria, often described as the world's first major seat of learning.

A powerful method for extracting information from supposedly secure systems is side-channel attacks: cryptanalytic techniques that rely on information unintentionally leaked by computing devices. Most side-channel attack research has focused on electromagnetic emanations (TEMPEST), power consumption and, recently, diffuse visible light from CRT displays. The oldest eavesdropping channel, namely acoustic emanations, has received little attention. Our preliminary analysis of acoustic emanations from personal computers shows them to be a surprisingly rich source of information on CPU activity.

Entanglement between a photon and a trapped atom has been directly observed for the first time, offering a method for establishing links between quantum memories over appreciable distances. Entanglement--a sort of arranged marriage between two or more particles--has usually been directly measured between species of the same kind, such as all photons or all atoms.

Opportunity's Microscopic Imager found this intriguing object, looking more like Rotini pasta. Its odd shape has stirred up Mars researchers, both inside and outside of the NASA Mars Rover Exploration team. Whether or not this object is related to biology has prompted a variety of views.

Voice-stress analysis, an alternative to the polygraph as a method for lie detection, is already widely used in police and insurance fraud investigations. Now, however, it is being touted as a powerful and effective tool for an array of new applications -- everything from the screening of potential terrorists in the nation's airports to catching wayward spouses in messy marital disputes. Despite its booming popularity, a number of federally sponsored studies have found little or no scientific evidence to support the notion that existing voice-stress technologies are capable of consistently detecting lies and deceptions.

Jan. 29, 2004 — The Inca invented a powerful counting system that could be used to make complex calculations without the tiniest mistake, according to an Italian engineer who claims to have cracked the mathematics of this still mysterious ancient population.

Recent studies are investigating the hypothesis that elaborated knotted strings known as khipu contain a hidden written language stored following a seven-bit binary code. Nobody, however, had been able to explain the meaning of these geometrical tablets known as yupana.

Different in size and shape, the yupana had been often interpreted as a stylized fortress model. Some scholars also interpreted it as a counting board, but how the abacus would have worked remained a mystery.

"It took me about 40 minutes to solve the riddle. I am not an expert on pre-Columbian civilizations. I simply decoded a 16th century drawing from a book on mathematical enigmas I received as a Christmas present," engineer Nicolino De Pasquale said.

Pictures from Nasa’s roving Mars buggy have astonished scientists by indicating that it may have landed in mud.

The Voynich manuscript may be elegant gibberish.

A strange sixteenth-century book may be cunningly crafted nonsense, says a computer scientist. Gordon Rugg has used the techniques of Elizabethan espionage to recreate the Voynich manuscript, which has stumped code-breakers and linguists for nearly a century.
