Cola Consumption Can Lead To Muscle Problems 420

wjousts writes "As I'm sure many Slashdot readers live almost exclusively on cola drinks, a new warning from doctors: 'Doctors have issued a warning about excessive cola consumption after noticing an increase in the number of patients suffering from muscle problems, according to the June issue of IJCP, the International Journal of Clinical Practice. ... 'Evidence is increasing to suggest that excessive cola consumption can also lead to hypokalaemia, in which the blood potassium levels fall, causing an adverse effect on vital muscle functions.' And sorry, diet colas aren't any better."

Craigslist Fights Back, Sues SC Atty General 286

FredMastro writes "Craigslist has now stepped past just asking for an apology. The Wall Street Journal and CNet report that Craigslist is fighting back. 'Craigslist said it has sued South Carolina Attorney General Henry McMaster, in the latest escalation of a battle over adult-oriented ads on the company's site. Jim Buckmaster, Craigslist's chief executive, said in a blog post that the company filed its suit in federal court in South Carolina. ...'" Unfortunately, the WSJ's piece requires a subscription, but reader Locke2005 adds a link to coverage in the San Jose Business Journal.

Special Effects Lessons From JJ Abrams' Star Trek 461

brumgrunt writes "JJ Abram's hugely successful — on many levels — reboot of Star Trek has, for Den Of Geek, brought to the fore a lesson about special effects that many movie makers have been missing. Surely it's time now that special effects were actually used properly?" (The new film is not without some goofs, though only a few of the ones listed by Movie Mistakes' nitpickers are sciency.)

Energy Secretary Chu Endorses "Clean Coal" 464

DesScorp writes "The Wall Street Journal is reporting that Energy Secretary Steven Chu is endorsing 'clean coal' technology and research, and is taking a pragmatic approach to coal as an energy supply. '"It absolutely is worthwhile to invest in carbon capture and storage because we are not in a vacuum," Mr. Chu told reporters Tuesday following an appearance at an Energy Information Administration conference. "Even if the United States or Europe turns its back on coal, India and China will not," he said. Mr. Chu added that "quite frankly I doubt if the United States will turn its back on coal. We are generating over 50% of our electrical energy from coal."' The United States has the world's largest reserves of coal. Secretary Chu has reversed his positions on coal and nuclear power, previously opposing them, and once calling coal 'My worst nightmare.'"

NASA Taking Ethernet Into Deeper Space 77

coondoggie writes "While Ethernet technology has gone places no one would have envisioned 36 years ago, NASA today signed an agreement with a German Ethernet vendor to build highly fault-tolerant networks for space-based applications. TTTech builds a set of time-triggered services called TTEthernet that is implemented on top of standard IEEE802.3 Ethernet. Its technology is designed to enable design of synchronous, highly dependable embedded computing and networking, capable of tolerating multiple faults, the company said."

Confusion Reigns As Analog TV Begins Shutdown 434

As TV stations across the country switch off their analog signals, uncertainty reigns. Some 691 stations will have converted to digital broadcasting by midnight tonight (some interpreted the mandate as going digital by Feb. 17, not during Feb. 17, and shut down yesterday). This represents about a third of TV broadcasters nationwide. No one can say how many of the estimated 5.8 million households unready for the transition are in areas served by the stations that are switching now. The FCC added to the uncertainty by imposing extra conditions, making it unclear until last Friday exactly which stations would be switching at the beginning of the transition period. The article quotes a former analyst at Barclays Capital who said the whole process has been "botched politically."

Conflict of Interest May Taint DTV Delay Proposal 339

Anonymous writes "Ars Technica has discovered that one of the Obama transition team members advising on the digital TV transition has a conflict of interest that would benefit WiMAX carrier Clearwire over Verizon. 'Barack Obama's call to delay the DTV transition would affect not only millions of analog TV viewers, but also powerful companies with a vested interest in the changeover date — including at least one with an executive on Obama's transition team.'"

Multiple Asteroid Belts Found Orbiting Nearby Star 135

Kligat writes "Scientists have found two asteroid belts around the star Epsilon Eridani, the ninth closest star to our solar system. Epsilon Eridani also possesses an icy outer ring similar in composition to our Kuiper Belt, but with 100 times more material, and a Jovian mass planet near the edge of the innermost belt. Researchers believe that two other planets must orbit the 850 million year old star near the other two belts. Terrestrial planets are possible, but not yet indicated."

Interplanetary Internet Tested In Space 124

Anonymous Coward writes "After Vint Cerf planned the Interplanetary Internet, there's a press release saying that the Interplanetary Internet is now being tested in space, using the Bundle Protocol developed by the Delay-Tolerant Networking Research Group. There's a conference paper with details on the testing too. These guys were previously the first to test IPv6 in space. Now they've found something with even fewer users than IPv6 to play with!"

VR Study Says 40% of Us Are Paranoid 221

Roland Piquepaille writes "UK researchers have recently used virtual reality to check if people had paranoid thoughts when using public transportation. Their VR tube ride experiment revealed that 40% of the participants experienced exaggerated fears about threats from others. Until now, researchers were relying on somewhat unreliable questionnaires to study paranoid thoughts which are often triggered by ambiguous events such as someone laughing behind their back. With the use of VR, psychiatrists and psychologists have a new tool which can reliably recreate social interactions. As the lead researcher said, VR 'is a uniquely powerful method to detect those liable to misinterpret other people.'."

Physicist Calculates Trajectory of Tiger At SF Zoo 713

KentuckyFC writes "Is it really possible for a 350-pound tiger to leap a 12.5-foot barrier from 33 feet away? (Said another way: a 159-kg tiger, a 3.8 m barrier, and 10 m away.) A physicist at Northeastern University has done the math, a straightforward problem in ballistics, and the answer turns out to be yes (abstract on the physics arXiv). But I guess we already knew that following the death of Carlos Souza at the paws of Tatiana, a Siberian Tiger he had allegedly been taunting at San Francisco zoo at the end of last year."
