Submission + - Identical Twins Not Identical After All

Hugh Pickens writes: "Contrary to previous beliefs, identical twins are not genetically identical. Researchers studied 19 pairs of monozygotic, or identical, twins and found differences in copy number variation in DNA which occurs when a set of coding letters in DNA are missing, or when extra copies of segments of DNA are produced. In most cases, variation in the number of copies likely has no impact on health or development but in others, it may be one factor in the likelihood of developing a disease (pdf). "Those differences may point the way to better understanding of genetic diseases when we study so-called discordant monozygotic twins....a pair of twins where one twin has a disorder and the other does not," says Carl Bruder, Ph.D. "If twin A develops Parkinson's and twin B does not, the region of their genome where they show differences is a target for further investigation to discover the basic genetic underpinnings of the disease.""

Submission + - Building the Interplanetary Internet

sighted writes: "Internet pioneer Vint Cerf is leading a NASA effort to create a permanent network link to Mars within the next two years. As Cerf outlined in a recent talk, the "InterPlaNet" protocol is designed to handle the delay caused by interplanetary distances. For example, it can take a signal up to 20 minutes to travel between the Earth and Mars, depending on the distance between the two planets."

Scientists Make Quantum Encryption Breakthrough 156

Madas writes "Scientists working in Cambridge have managed to make quantum encryption completely secure (registration required) by putting decoy pulses in the key transmission stream. According to the story this paves the way for safe, encrypted high-speed data links. Could this allow completely private transmission of data away from snooping eyes and ears? Or will it mean film studios can stop movies from being copied when traveling on the internet?"

Submission + - College Students Illegally Sharing

An anonymous reader writes: The IndyStar has an article about how copyright infringement is rampant on college campuses here. The article explains that if the schools do nothing about it, they could be subject to lawsuits. However, the punishments used by the school don't appear to be too harsh for the first couple offenses.

Skype Asks FCC to Open Cellular Networks 292

Milwaukee's_Best writes "Skype has just asked the FCC to force wireless phone companies to open their networks to all comers. Skype essentially wants to turn the wireless phone companies into just another network of the kind currently operated on the ground. This would require carriers to allow any phone to be used on their networks, and for any application. Users would simply purchase a voice or data plan (though these could easily converge into a data plan if VoIP calling is used) and then use the device of their choice to access the network of their choice. Think of it as network neutrality for cell networks. Given the competition that exists within the industry, is this needed?"
