Study: Earth microbes could survive Martian conditions

The Mars Curiosity rover recently detected signs of organic compounds on the Red Planet, but NASA won't call the findings definitive. One holdup is the issue of contamination. The trace amounts may be the result of contamination from the rover itself.

The contamination issue could rear its head again should the rover or future expeditions turn up any microbes. Finding microbes on Mars would be a cause for scientific celebration, but a study published in "Proceedings of the National Academy of Sciences of the United States of America" shows that Earth microbes could very well survive in the brutal conditions on Mars.… Read more

Policy and privacy: Five reasons why 2012 mattered

This was the year of Internet activism with a sharp political point to it: Protests drove a stake through the heart of a Hollywood-backed digital copyright bill, helped derail a United Nations summit, and contributed to the demise of a proposed data-sharing law.

In 2012, when Internet users and companies flexed their political muscles, they realized they were stronger than they had thought. It amounted to a show of force not seen since the political wrangling over implanting copy-protection technology in PCs a decade ago, or perhaps since those blue ribbons that appeared on Web sites in the mid-1990s in … Read more

Revealed: NSA targeting domestic computer systems in secret test

Newly released files show a secret National Security Agency program is targeting the computerized systems that control utilities to discover security vulnerabilities, which can be used to defend the United States or disrupt the infrastructure of other nations.

The NSA's so-called Perfect Citizen program conducts "vulnerability exploration and research" against the computerized controllers that control "large-scale" utilities including power grids and natural gas pipelines, the documents show. The program is scheduled to continue through at least September 2014.

The Perfect Citizen files obtained by the Electronic Privacy Information Center and provided to CNET shed more … Read more

NRA's Facebook page shuttered, Twitter activity halted

In the wake of the Newtown tragedy, when an armed man stormed a Connecticut elementary school and killed 26 people, including 20 children, gun control has been under high scrutiny from both lawmakers and citizens.

The National Rifle Association -- the longtime champion of gun ownership rights -- has stayed conspicuously out of the debate, however. So much so, that it has even ceased all of its social media activity -- its Facebook page was recently shuttered and the group has not posted a single new tweet on its Twitter account.

The last tweet from the NRA was posted at … Read more

U.N. summit's meltdown ignites new Internet Cold War

news analysis When the history of early 21st century Internet politicking is written, the meltdown of a United Nations summit last week will mark the date a virtual Cold War began.

In retrospect, the implosion of the Dubai summit was all but foreordained: it pitted nations with little tolerance for human rights against Western democracies which, at least in theory, uphold those principles. And it capped nearly a decade of behind-the-scenes jockeying by a U.N. agency called the International Telecommunication Union, created in 1865 to coordinate telegraph connectivity, to gain more authority over how the Internet is managed.

It … Read more

U.N. summit implodes as U.S., others spurn Internet treaty

In a stunning repudiation of a United Nations summit, an alliance of Western democracies including the United States, the United Kingdom, and Canada today rejected a proposed treaty over concerns it hands repressive governments too much authority over the Internet.

"This conference was never meant to focus on Internet issues," said ambassador Terry Kramer, head of the U.S. delegation to the Dubai summit. "The Internet has given the world unimaginable economic and social benefit during these past 24 years -- all without U.N. regulation."

Delegates from the Netherlands, New Zealand, Denmark, Sweden, the Philippines, … Read more

U.N. summit derailed over human rights controversy

A United Nations summit suddenly ran aground today after China, Algeria, and Iran objected to a U.S.-backed proposal that would include a mention of "human rights obligations" in a proposed telecommunications treaty.

Algeria's delegate warned at the U.N. summit in Dubai that there were many other nations -- calling them "silent member states" -- that also opposed the human rights language and forced a temporary adjournment of the proceedings.

China criticized the human rights language as well, saying "we also have a very serious question about the necessity of the existence … Read more

U.N. summit rejects U.S., Europe hands-off-the-Internet plea

Delegates to a United Nations summit agreed today that a U.N. body should take a more "active" role in shaping the future of the Internet, a move that had been opposed by the United States and its allies that had warned of greater government control.

The agreement by delegates from the International Telecommunication Union's 192 member nations, a majority of whom raised their placards in support of the language, took place after 1:30 a.m. local time in Dubai. It came after the head of the ITU, a U.N. agency, had promised not to … Read more

U.N. proposal renews concerns of Internet power grab

A United Nations agency has used a summit in Dubai to renew its efforts to gain more control over how the Internet is managed.

The International Telecommunication Union, a U.N. agency, has circulated draft language, which was leaked today, that would let the organization take what it describes as a more "active" Internet role in the future.

It shows that the ITU would become involved in "Internet-related technical, development and public policy issues" -- a broad phrase that sweeps in hot-button areas including cybersecurity, spam, surveillance, and censorship.

The draft document (PDF) was disclosed the … Read more
