Researchers from nearby Reading University employed a new methodology during this summer's dig season at the Roman site, excavating with the help of new technologies for streamlining the archaeological process. The innovations, collectively known as e-science, threaten to shrug off archeology's antiquated image. … [Read more...] about Archaeologists Go Digital
This bird's-eye view showed the remains of large, circular ditches. This seemed peculiar, so Boschi and her colleagues began doing groundwork. At first, they used electrical resistance, which puts electrical currents into the ground and monitors for anomalies in how current flows through the soil. The team also used magnetic surveys to detect if any metal artifacts were lurking underground. … [Read more...] about Princely tomb of Iron Age mystery man discovered in Italy.

Seventeen-year-old swimmer Missy Franklin has already captured one gold medal in the 2012 London Olympics, winning the 100-meter backstroke. She'll aim for gold again Friday (Aug. 3) in the 200-meter backstroke. To succeed, she'll simply need to take advantage of the lessons of fluid dynamics. … [Read more...] about Pool Power: How Olympian Missy Franklin Overcomes Drag
At 10:56pm EDT on July 20, 1969, American astronaut Neil Armstrong became the first human being to ever step foot on any extraterrestrial body. His initial words of "that's one small step for (a) man, one giant leap for mankind" were heard around the world and have echoed through time ever since. Earlier today—43 years after his historic mission, a few weeks after he turned 82 years old and underwent heart surgery to relieve blocked arteries—Neil Armstrong passed away. … [Read more...] about A hero for all mankind, Neil Armstrong passes at age 82
Earlier this year, Ars visited the Navy's USS Rancocas, the "Cruiser in the Cornfield" (also known as the Vice Admiral James H. Doyle Combat Systems Engineering Development Site) and the neighboring Lockheed Martin Aegis assembly operation in Moorestown, New Jersey. Moorestown is where every radar system is given its final "burn in" before delivery. There, we got a walk-through of the guts of an operating Aegis radar room. While Lockheed Martin and the Navy have tested an active phased array version of the SPY-1 (designated the SPY-1E SBARS)—in which each of the more than 4,000 transmitting "radiators" generate its own signal—all the currently deployed SPY-1 systems use passive arrays. The radiators have radio energy generated by eight transmitters pushed through them via a maze of wave guides. (I was not certain if it was the large amount of coffee that I had consumed that day or the several megawatts of radio energy passing inches above my head that made me feel jittery). … [Read more...] about As N.
