KentuckyFC writes “Steganography is the art of hiding a message in such a way that only the sender and receiver realize it is there. (By contrast, cryptography disguises the content of a message but makes no attempt to hide it.) The central problem for steganographers is how much data can be hidden without being detected. But the complexity of this problem has meant it has been largely ignored. Now two personal scientists (one working for Google) have made a major theoretical breakthrough by tackling the problem in the same way that the electrical engineer Claude Shannon calculated the capacity of an ordinary communications channel in the 1940s. In Shannon’s theory, a transmission is considered successful if the decoder properly determines which message the encoder has sent. In the stego-channel, a transmission is successful if the decoder properly determines the sent message without anybody else detecting its presence (abstract). Studying a stego-channel in this way leads to some counter-intuitive results: for example, in certain circumstances, doubling the number of algorithms looking for hidden data can increase the capacity of the steganographic channel”

Some great news for Apple Inc.’s (NASDAQ: AAPL) revolutionary iPhone today, as a new study shows that for the first time ever, Apple has moved ahead of competitor Research in Motion Limited (NASDAQ: RIMM) for second place in overall smartphone market share.

Top slot remains firmly in the hands of Nokia Corporation (ADR) (NYSE: NOK), but the current data may start to give the perennial champion some reason for concern. While its current lead in market share domination remains well above its next closest competitor, but the figures are much closer than what they were this time last year, another indication of just how popular the iPhone has become over the past year.

Last year at this time, Nokia had a very tight grip on the market, with a reported 51.4% control of the market. It’s next closest competitor was Research in Motion, which had 10.6% market share.

New Scientist reviews the possibility that the Cassini probe might be repurposed to look for signs of life on Saturn’s enigmatic moon Enceladus. “[Enceladus’ water vapor] plume’s origin is still being debated, but some models recommend the moon holds an ocean of liquid water beneath its surface. This ocean could be a potential habitat for extraterrestrial life. … Though the probe was never designed to look for life, it could do so by studying organic chemicals such as methane in the plume, the team says.”

Death Metal sends in a Scientific American article reporting that 2,000 of 6,000 amphibian species are endangered worldwide. A combination of environmental assaults, including global warming, seems to be responsible. “… national parks and other areas protected from pollution and development are providing no refuge. The frogs and salamanders of Yellowstone National Park have been declining since the 1980s, according to a Stanford University study, as global warming dries out seasonal ponds, leaving dried salamander corpses in their wake. Since the 1970s, nearly 75 percent of the frogs and other amphibians of La Selva Biological Station in Braulio Carrillo National Park in the Caribbean lowlands of Costa Rica have died, perhaps due to global warming. But the really bad news is that amphibians might be just the first sign of other species in trouble. Biologists at the University of California, San Diego, have shown that amphibians are the first to respond to environmental changes, thanks to their sensitivity to both air and water. What goes for amphibians may soon be true of other classes of animal, including mammals.”

miller60 writes “News sites and political blogs are expecting extraordinary traffic tonight as Americans track results of the Presidential election, and are scaling their infrastructure to meet the challenge. Yahoo expects its Election Night traffic might be three times the volume seen in 2004, when it had 80 million page views on Election Day and 142 million more visits the following day. Hosting companies say customers have been ordering extra servers and load balancing services, while content delivery networks are also anticipating a busy night. Will traffic approach record levels? Akamai’s Net Usage Index, which tracks traffic to its customer news sites, is one metric to watch.”
