sciencehabit writes "It's a debate that has vexed scientists for decades: Is the Grand Canyon young or old, geologically speaking? Both, a new study declares. A group of scientists reports that the famed formation is a hybrid of five different gorges of various ages--two of three middle segments formed between 70 million and 50 million years ago and between 25 million and 15 million years ago, but the two end segments were carved in the past 5 million to 6 million years--and the Colorado River only tied them into a single continuous canyon 5 million or 6 million years ago."
hackingbear writes "The Chinese moon rover, Jade Rabbit, encountered an abnormality in its control mechanism before its planned sleep during the 14-day-long lunar night. In the form of a diary, the Jade Rabbit said, "The shi-fu ('kung-fu masters,' meaning the scientists and engineers) are working around the clock trying to fix the problem and their eyes look like a rabbit's (red due to fatigue), but I may not be able to survive over this lunar night." (translated, original in Chinese.) The rover landed on the moon on Dec 14 and was designed to operate for three months."
New submitter pefisher writes "The British are apparently admitting that they track their citizens as they travel the world (through information provided by intelligence agencies) and are arresting them if they have been somewhere that frightens them. 'Sir Peter, who leads the Association of Chief Police Officer's "Prevent" strategy on counter-terrorism, told BBC Radio 4's Today programme that those returning from Syria "may well be charged and investigated, but they will be put into our programmes".' The program seems to consist of being spied on by the returnee's cooperative neighbors."
From Ars Technica comes this update in the defamation case filed by climate researcher Michael Mann against political commentator Mark Steyn of National Review magazine, who rhetorically compared Mann to Penn State coach Jerry Sandusky and accused him of publishing intentionally misleading research results. "The defendants tried to get it dismissed under the District of Columbia's Strategic Lawsuit Against Public Participation (SLAPP) statute, which attempts to keep people from being silenced by frivolous lawsuits. The judge hearing the case denied the attempt and then promptly retired; Mann next amended his complaint, leading an appeals court to send the whole thing back to a new trial judge. Now the new judge has denied the SLAPP attempt yet again. In a decision released late last week (and hosted by defendant Mark Steyn), the judge recognizes that the comparison to a child molester is part of the "opinions and rhetorical hyperbole" that are protected speech when used against public figures like Mann. However, the accompanying accusations of fraud are not exempt:"
The L.A. Times reports that a group of students and parents, fed up with what they see as overarching job security in California schools, are suing in the hopes of making harder for poor teachers to stay on the books. From the article: "The lawsuit, filed by the nonprofit, advocacy group Students Matter, contends that these education laws are a violation of the Constitution's equal protection guarantee because they do not ensure that all students have access to an adequate education. Vergara versus California, filed on behalf of nine students and their families, seeks to revamp a dismissal process that the plaintiffs say is too costly and time consuming, lengthen the time it takes for instructors to gain tenure and dismantle the 'last hired, first fired' policies that fail to consider teacher effectiveness. The lawsuit aims to protect the rights of students, teachers and school districts against a "gross disparity" in educational opportunity, lawyers for the plaintiffs said." Perhaps related.
Rydia writes "Since it first released, I have been in love with my Nokia N900, and it has satisfied all my needs for a mobile with a high degree of control and utility. Sadly, the little guy is showing his age, both in battery life (even with the powersaving kernel options enabled), and performing in general has been left far, far in the dust by phones that are now considered quite old. The time has come to find its successor, but after a thorough search of smartphone options, I can't find any handset that offers everything for the power user that the N900 did (much less a hardware keyboard). I'd like to avoid supporting Google/Android, but there don't seem to be many options. Have any other techies found a replacement for their N900?"
VentureBeat is one of the many outlets featuring recently surfaced video of Steve Jobs doing an early demo of the Macintosh, 30 years ago. I remember first seeing one of these Macs in 1984 at a tiny computer store in bustling downtown Westminster, Maryland, and mostly hogging it while other customers (or, I should say, actual customers) tapped their feet impatiently.
Nerval's Lobster writes "A team of researchers at Virginia Tech University have developed a battery with energy density an order of magnitude higher than lithium-ion batteries, while being almost endlessly rechargeable and biodegradable as well – because it's made of sugar. The battery is an enzymatic biofuel fuel cell – a type of fuel cell that uses a catalyst to strip molecules from molecules of a fuel material. Instead of using platinum or nickel for catalysts, however, biofuel cells use the catalysts made from enzymes similar to those used to break down and digest food in the body. Sugar is a good fuel material because it is energy dense, easy to obtain and transport, and so simple to biodegrade that almost anything biological can eat it. Sugar-based fuel cells aren't new, but existing designs use only a small number of enzymes that don't oxidize the sugar completely, meaning the resulting battery can hold only small amounts of energy that it releases slowly. A new design that uses 13 enzymes that can circulate freely to get better access to sugar molecules, however, is able to store energy at a density of 596 amp-hours per kilogram – an order of magnitude higher than lithium-ion batteries, according to Y.H. Percival Zhang, who studies biological systems engineering at the College of Agriculture and Life Sciences and College of Engineering at Virginia Tech. "Sugar is a perfect energy storage compound in nature," Zhang said in a statement announcing publication in Nature Communications of his paper describing the battery. "So it's only logical that we try to harness this natural power in an environmentally friendly way to produce a battery.""
schwit1 writes "Despite initial high expectations, the Indian Air Force appears to be souring on a joint development deal with Russia for a new fifth-generation fighter jet, according to the Business Standard, a major Indian business publication. The Russian prototype is 'unreliable, its radar inadequate, its stealth features badly engineered,' said Indian Air Force Deputy Air Marshall S Sukumar at a Jan. 15 meeting, according to minutes obtained by the Business Standard. 'They're very good at building airplanes,' Cordesman said. 'The problem that Russia, since the collapse of the former Soviet Union, has been putting out the military equivalent of show cars. They look good, but it isn't always clear how practical they are and how many of the specifications they can actually meet.'"
phmadore writes "Version 1.4.0 (.TAR.GZ)of the most intellectually challenging OSS game out there (IMO), OpenTTD (Open Transport Tycoon Deluxe), is near at hand. Of course, most servers are still running 1.3.3 (the last stable, major version change, from November/December-ish). N-Ice.org typically waits until a stable release has been around for a minute to implement the changes into its online client (which is as yet unavailable as a binary for Linux; it varies only slightly from the official release and non-Windows users are able to interface with it no problem), but there are exciting developments coming down the pipe for OpenTTD. 'The new SSE blitters were also further improved. Not immediately noticeable but useful in the future, are the new string codes to display amounts of cargo in NewGRFs. For our Korean users, the separators in numbers were fixed.' Here is some information on the history of OTTD."
An anonymous reader writes "Tensions are high at Bletchley Park between the new management who want a 21st century installment and the volunteers who want to show the whole story (and get dismissed for doing so). This report [Note: video, with sound] is from the BBC: 'The groundbreaking intelligence work carried out at Bletchley Park during the second world war was credited with bringing forward the end of the conflict. In 2011 the site was awarded a £4.6m grant from the Heritage Lottery Fund (HLF). But Bletchley is currently in the throes of a bitter dispute, between owners who want to create a brand new visitors centre, and volunteers who have been working on the site for years.'"
theodp writes "Valleywag reports on legendary Silicon Valley venture capitalist Tom Perkins' WSJ op-ed on class tensions, in which the KPCB founder and former HP and News Corp. board member likens criticism of the techno-affluent and their transformation of San Francisco to one of the most horrific events in Western history. 'I would call attention to the parallels of Nazi Germany to its war on its "one percent," namely its Jews, to the progressive war on the American one percent, namely the "rich,"' Perkins writes. 'There is outraged public reaction to the Google buses carrying technology workers from the city to the peninsula high-tech companies which employ them. We have outrage over the rising real-estate prices which these "techno geeks" can pay...This is a very dangerous drift in our American thinking. Kristallnacht was unthinkable in 1930; is its descendent 'progressive' radicalism unthinkable now?"'"
MojoKid writes "There's no disputing that Bill Gates is blessed with a brilliant mind. Sure, he dropped out of Harvard College, but he got accepted into the elite institution of higher learning in the first place. Leading into his college career, Gates scored 1,590 out of 1,600 on the SAT. The rest is history — he went on to co-found Microsoft, built a net worth that's in the billions ($76.8 billion at last count), and now spends his time on his philanthropic efforts. Regardless, it took 23-year-old Magnus Carlsen, a "grandmaster" Chess player since the age of 13 and new world Chess champion, just 71 seconds to defeat Gates in a friendly game of Chess on a Norwegian television show. It takes longer to heat up a cup of water in the microwave."
An anonymous reader points out this recently published study (PDF) on detecting malicious (or at least suspicious) Tor exit relays. From their conclusions: "After developing a scanner, we closely monitored all ~1000 exit relays over a period of four months. Wed discovered 25 relays which were either outright malicious or simply misconfigured. Interestingly, the majority of the attacks were coordinated instead of being isolated actions of independent individuals. Our results further suggest that the attackers made an active effort to remain under the radar and delay detection." One of the authors, Philipp Winter, wrote a followup blog post to help clarify what the paper's findings mean for Tor users, including this clarification: "First, it's important to understand that 25 relays in four months isn't a lot. It is ultimately a very small fraction of the Tor network. Also, it doesn't mean that 25 out of 1,000 relays are malicious or misconfigured (we weren't very clear on that in the paper). We have yet to calculate the churn rate of exit relays which is the rate at which relays join and leave the network. 1,000 is really just the approximate number of exit relays at any given point in time. So the actual number of exit relays we ended up testing in four months is certainly higher than that. As a user, that means that you will not see many malicious relays 'in the wild."
The San Francisco Chronicle reports that "A federal judge overturned a jury's multimillion-dollar damage award to the programmer of the original John Madden Football video game on Wednesday, saying there was no evidence that his work was copied for seven years, without credit, by the marketer of later versions of the hugely successful game. The ruling by U.S. District Judge Charles Breyer of San Francisco spared Electronic Arts Inc. from nearly $4 million in damages, plus interest that could have exceeded $7 million. The jury verdict also could have led to larger damages against the company for later versions of the game, which reaped billions of dollars in revenues, if future juries found that those, too, had been lifted from the work of programmer Robin Antonick."
