New Evidence For Oceans of Water Deep In the Earth 190

techtech (2016646) writes Researchers from Northwestern University and the University of New Mexico report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form—the ingredients for water are bound up in rock deep in the Earth's mantle—the discovery may represent the planet's largest water reservoir. This research was published in Science.

NASA Forming $3M Satellite Communication, Propulsion Competition 9

coondoggie (973519) writes NASA took the next step in forming a large-scale, $3 million competition to build advanced propulsion and communications technologies for small, inexpensive satellite systems known as cubesats. The Cubesat Lunar Challenge will be broken up into two areas: propulsion and communication while in orbit around the moon. In Request For Information published this week, NASA said the two challenges would provide competitive opportunities for a variety of competition teams to deploy cubesats on a NASA or third-party provided launch.

US Pushing Local Police To Keep Quiet On Cell-Phone Surveillance Technology 253

schwit1 (797399) writes with this story from the Associated Press, as carried by Yahoo News: The Obama administration has been quietly advising local police not to disclose details about surveillance technology they are using to sweep up basic cellphone data from entire neighborhoods, The Associated Press has learned. Citing security reasons, the U.S. has intervened in routine state public records cases and criminal trials regarding use of the technology. This has resulted in police departments withholding materials or heavily censoring documents in rare instances when they disclose any about the purchase and use of such powerful surveillance equipment. Federal involvement in local open records proceedings is unusual. It comes at a time when President Barack Obama has said he welcomes a debate on government surveillance and called for more transparency about spying in the wake of disclosures about classified federal surveillance programs.

Ask Slashdot: PC-Based Oscilloscopes On a Microbudget? 172

New submitter fffdddooo (3692429) writes I know it's something that people used to ask every few years, but answers get old so quickly. I'm an electronics teacher, and I'm wondering if it's possible to find some oscilloscope (and why not spectrum analyser?) for recommending to my students, to be able to work at home. I'm thinking of something near $50-$70. Two or three years ago, I'm sure the answer was No, but nowadays? The same reader points out two options spotted on Amazon: one that's "very cheap but Khz" (it's also a kit that requires assembly), and another that aims to be capable of 20MHz, 2-channel operation. What's out there, he'd like to know, that's not junk?

Why United States Patent Reform Has Stalled 139

ectoman (594315) writes Proponents of patent reform in the United States glimpsed a potential victory late last year, when the House of Representatives passed H.R. 3309, the Innovation Act, designed to significantly mitigate patent abuse. Just months ago, however, the Senate pulled consideration of the bill. And since then, patent reform has been at a standstill. In a new analysis for Opensource.com, Mark Bohannon, Vice President of Corporate affairs and Global Public Policy at Red Hat, explains three reasons why. "For this year, at least," he writes, "the prospect of addressing abusive patent litigation through Congressional action is on ice"—despite the unavoidable case for reform.

mrspoonsi (2955715) writes Mozilla, the organisation behind the Firefox browser, has announced it will start selling low-cost smartphones in India within the "next few months". Speaking to the Wall Street Journal, the firm's chief operating officer suggested the handsets, which will be manufactured by two Indian companies, would retail at $25 (£15) [note: full article paywalled]. They will run Mozilla's HTML5 web-based mobile operating system, Firefox OS. The firm already sells Firefox-powered phones in Europe and Latin America. Firefox OS has come a long way even in the year since we saw a tech demo at Linux Fest Northwest.

The Government Can No Longer Track Your Cell Phone Without a Warrant 173

Jason Koebler (3528235) writes The government cannot use cell phone location data as evidence in a criminal proceeding without first obtaining a warrant, an appeals court ruled today, in one of the most important privacy decisions in recent memory. "In short, we hold that cell site location information is within the subscriber's reasonable expectation of privacy," the United States Court of Appeals for the Eleventh Circuit ruled. "The obtaining of that data without a warrant is a Fourth Amendment violation."
