Scientists Demonstrate Mind-Controlled Robot


"On Tuesday, a team at Switzerland’s Federal Institute of Technology in Lausanne used only a simple head cap to record the brain signals of Mark-Andre Duc, who was at a hospital in the southern Swiss town of Sion 162 miles away.

"Mr. Duc’s thoughts - or rather, the electrical signals emitted by his brain when he imagined lifting his paralyzed fingers - were decoded almost instantly by a laptop at the hospital.

"The resulting instructions - left or right - were then transmitted to a foot-tall robot scooting around the Lausanne lab....The robot itself is an advance on a previous project that let patients control an electric wheelchair."


Art Is Long; Copyrights Can Even Be Longer


"Artists’ copyright is frequently misunderstood. Even if a painting (or drawing or photograph) has been sold to a collector or a museum, in general, the artist or his heirs retain control of the original image for 70 years after the artist’s death.

"Think of a novel. You may own a book, but you don’t own the writer’s words; they remain the intellectual property of the author for a time.

"So while MoMA owns the actual canvas of “Les Demoiselles,” the family of Picasso, who died in 1973, still owns the image. And under existing law, the estate will continue to own the copyright until 2043.

"If someone wants to reproduce the painting — on a Web site, a calendar, a T-shirt, or in a film — it is the estate that must give its permission, not the museum."  





Senate rejects measure to nullify union rules:  
Democrats support new regulations

"The Senate rejected a Republican attempt Tuesday to overturn new regulations designed to give unions quicker representation elections in their effort to organize more workplaces.



"Under the existing regulations, workers typically vote within 45 to 60 days after a union gathers enough signatures from workers saying they want to hold an election. The new rules could cut that time by days or even weeks by simplifying procedures and putting off some challenges until after the election is held, cutting back hearings and reducing legal delays.


"Unions call the changes a modest fix to prevent companies from using stalling tactics to delay a vote while workers can be subject to harassment, threats and even illegal firing. Republicans argue the new rules will lead to “ambush” elections that barely leave company managers enough time to respond or counsel against forming a union."

"Washington (CNN) -- President Barack Obama announced Monday that he has signed an executive order allowing new sanctions against companies that enable Syria and Iran to use technology such as cell phone monitoring to carry out human rights abuses.

"The order is part of a broader strategy intended to strengthen the administration's ability to prevent atrocities, including creation of an Atrocities Prevention Board, Obama said in somber remarks at the U.S. Holocaust Memorial Museum to mark Holocaust Remembrance Day.

" "These technologies should be in place to empower citizens, not to repress them," Obama said of the measure, which targets the Syrian and Iranian governments, as well as companies that provide them with high-tech equipment to use against their own people."


"A new study says that for the first time since the Great Depression, there may be fewer Mexican immigrants coming into the United States than there are moving from the United States back to Mexico. According to the Pew Research Center, the net migration between the U.S. and Mexico over the last five years was essentially zero, and the downward trend suggests that flow of both legal and illegal immigrants may have actually reversed back toward Mexico.

"There are many possible reasons to explain the decline, but the most obvious one would seem to be the struggling U.S. economy, which has cost millions of available jobs, particularly in construction and in the South, where recent immigrants generally thrive. There have also been big increases in enforcement, deportations, and border security, although the report also says that arrests of illegal immigrants trying to cross the border has actually plummeted by nearly 75%. Whether that's because fewer people want to come here or they just don't think it's worth the risk is hard to pin down, but the number of folks willing to take the chance is definitely declining.

"Given the continued hysteria over illegal immigrants and how demographic shifts might change the country in the future, many Americans might be shocked to learn that the shift is actually heading in the other direction. There have been several state laws just within the last couple of years that were passed on the premise that illegal immigration was out of control, even as the population of Mexican immigrants is apparently lower than it has been in decades. (Some might argue that the news laws are responsible for that, but the trend was clearly in place even before they were passed.) The Supreme Court will actually hear arguments this week about the harsh Arizona law that has been at the center of the debate for the last couple years, but this new evidence may put the crackdown in a new light, since the problem it was intended to resolve may not actually exist."  from Dashiell Bennett @ The Atlantic Wire


"Social Security and Medicare, the government-run health plan for senior citizens, are together the largest U.S. public benefit programs and account for one-third of the federal budget. The programs' costs are projected to grow rapidly because of the aging U.S. population and, in Medicare's case, the rising cost of health care....


"Treasury Secretary Timothy Geithner said the Obama administration would seek to work with Congress to come up with a long-term solution to repair the solvency of the disability trust fund but didn't offer specifics. "The best thing to do is a long-term solution," he said....

"Social Security's worsening outlook comes from a combination of higher cost-of-living adjustments pushing benefits up and lagging wage growth holding down tax revenue.

"In recent years, the Social Security disability rolls have soared, as many Americans with mental and physical health problems sought to enter the program and others with less severe issues applied because of a scarcity of work."  from Damian Paletta @ The WSJ

Call for Growth to Counter German Push for Austerity

BERLIN — "With political allies weakened or ousted, Chancellor Angela Merkel’s seat at the head of the European table has become much less comfortable, as a reckoning with Germany’s insistence on lock-step austerity appears to have begun.


" “The formula is not working, and everyone is now talking about whether austerity is the only solution,” said Jordi Vaquer i Fanés, a political scientist and director of the Barcelona Center for International Affairs in Spain....


"From trading floors to polling stations to the streets of cities across Europe, the message appears increasingly to be that countries cannot cut their way to fiscal health. They need growth, too. In recent months, powerful voices have joined the chorus, including those of the managing director of the International Monetary Fund, Christine Lagarde, and Italy’s prime minister, Mario Monti. Treasury Secretary Timothy F. Geithner has called repeatedly for Europe to defer budget cutting in favor of some form of stimulus spending.

Pressured by the presidential campaign, even Mr. Sarkozy, once Ms. Merkel’s most prominent ally, has begun to talk of the need for growth."  from Nicholas Kulish @ NYT:

"The gallery at Art Center College of Design in Pasadena is also on hand — albeit it coincidentally — to mark the passage of government near-exclusivity in space exploration. A large exhibition chronicles "The History of Space Photography" through May 6....

"Guest curator Jay Belloli worked with several consultants from the nearby Jet Propulsion Lab. (JPL, founded at Caltech and affiliated with NASA, has 23 spacecraft and 10 instruments conducting active missions, according to its website.) Belloli and his team selected 150 noteworthy images, most from the last 50 years of space exploration, and added three video projections that feature various celestial animations....

"The show includes classics, such as Edward Hubble's 1923 telescopic photograph verifying the existence of galaxies beyond our own Milky Way. Astronaut John Glenn's 1962 color photograph taken from the window of his orbital spacecraft is a kind of drive-by tourist snapshot on steroids (it shows the Georgia coastline). "The History of Space Photography" offers total visual fictions too, since images made from cameras performing digital scans gathered over time (sometimes many minutes) are composites; color is also always malleable and print size is arbitrary...."  from Christopher Knight, Los Angeles Times Art Critic

iBrain: A Mind Reading Machine

The iBrain is part of a new generation of portable neural devices and algorithms intended to monitor and diagnose conditions like sleep apnea, depression and autism.


The iBrain is part of a new generation of portable neural devices and algorithms intended to monitor and diagnose conditions like sleep apnea, depression and autism. Invented by a team led by Philip Low, a 32-year-old neuroscientist who is chief executive of NeuroVigil, a company based in San Diego, the iBrain is gaining attention as a possible alternative to expensive sleep labs that use rubber and plastic caps riddled with dozens of electrodes and usually require a patient to stay overnight.

“The iBrain can collect data in real time in a person’s own bed, or when they’re watching TV, or doing just about anything,” Dr. Low said.

Why the Coming Patent Crisis is Inevitable



 "At some point in the future, a company is going to skip the settlement and use the courts to shut down a popular and universal feature on the Web's top domains, simply because it has a patent that says it came up with the notion first. It will be a shock that reverberates all the way to the U.S. government and the World Trade Organization.

I suspect a patent crisis is both necessary and inevitable. The reason is simple: there isn't enough political will or pressure to institute massive patent reform without a crisis to rally around."




GSA chief gone: fallout continues in wake of lavish expense

"Tangherlini said in a letter of introduction to GSA employees that the agency was taking some immediate action "to ensure that our customers maintain their faith in our services." Those measure include a review of planned conferences and meetings that involve travel or substantial expenditures of public funds and the cancellation of a number of conferences that only or primarily involved staff, he said in the letter."


" "Groupon's internal controls were so poor and inadequate that Groupon's reported results were not reliable," shareholder Fan Zhang alleged, according to Bloomberg review of the complaint filed in federal court in Chicago....The lawsuit comes a day after reports that Groupon's revision of its first set of financial results as a public company had attracted the attention of the U.S. Securities and Exchange Commission, although the commission has reportedly not yet elected to launch a formal investigation of the company."


"Big Society Capital has £600m, of which the majority comes from unused cash in bank accounts that had been dormant for more than 15 years.  The fund will back social enterprises that prove they can repay an investment through the income they generate.  "This is about supplying capital to help society expand," said Prime Minister David Cameron."



"In its lawsuit, Yahoo claimed that Mark Zuckerberg's company's "entire social network model" was based on its technology, and infringed its rights to innovations involved in messaging, privacy controls, advertising, customisation and social networking.

Facebook is preparing for initial public offering on a stock market that could value Facebook at $100bn (£64bn).  Yahoo, which has struggled in recent years against competition from both Facebook and Google, has a market value of $18.3bn.  On Wall Street, Yahoo shares fell 28 cents on Tuesday to close at $15.18."




"One of the City's top bankers, Ian Hannam, has been fined £450,000 by the Financial Services Authority (FSA) for providing inside information to a prospective client.  Mr Hannam has resigned as chairman of Capital Markets at JP Morgan Cazenove, and is appealing against the decision.  A former captain in the territorial SAS, he said the FSA's conclusion was wrong and he had acted with integrity.

The FSA said that while Mr Hannam had not deliberately set out to commit market abuse, his failings were serious because of his experience and senior position at JP Morgan.  It claims he disclosed inside information in two emails sent to a prospective client towards the end of 2008."


"BRUSSELS — The European Union’s competition office on Tuesday opened two antitrust cases against Motorola Mobility for possibly abusing its patents following complaints by two rivals, Microsoft and Apple.

The cases are the latest stage in what has become a full-blown battle over the ownership of essential technologies that help power mobile and gaming devices, a fight that has engulfed Google and virtually all the other major players in the industry."


"Peter Gelb has both raised expectations and invited criticism by calling Robert Lepage’s $16 million production of Wagner’s “Ring” cycle for the Metropolitan Opera revolutionary. He used the word again in a recent interview at his office, as he spoke of the “trials and tribulations” of executing Mr. Lepage’s “superhuman,” technically daunting concept in a repertory theater “against amazing odds.”

"...But Mr. Gelb, the Met’s general manager since 2006, has been living it, attending every stage rehearsal and “complaining bitterly,” he said, about the persistent clankiness of the so-called machine, the 45-ton set of movable planks that dominate the production.He could be right....But for many people, making the set a character is the problem. The machine imposes itself and distracts us from Wagner’s music drama."

So, is this statistical debate over whether the poverty line is too high or too low missing the real issue?

What Does India’s Poverty Line Actually Measure?



Jean Drèze, an economist and former member of the National Advisory Council, certainly thinks so. “What is really shocking is not that the official poverty line is abysmally low, but that even with that abysmal benchmark, so many people are below it,” he told us. “The belated discovery that it is impossible to have a dignified life on the official poverty line draws our attention to the appalling living conditions of the Indian poor.” Taking a position diametrically opposed to Mr. Bhalla and Mr. Panagariya, Mr. Drèze argues, “The message about the terrifying nature of ‘hidden poverty’ in India has been somewhat lost in the din of the recent debate.”

NEW ORLEANS — Rarely has a national title seemed to yield so little to celebrate. The starting five for the champion Kentucky Wildcats — a mix of freshmen and sophomores — are expected to enter the N.B.A. draft, and never again play for the college they ever so briefly attended....

"Mark Emmert, the president of the National Collegiate Athletic Association, had already expressed regret that the N.B.A.’s so-called “one-and-done” rule allows universities to recruit athletes who show little interest in getting an education.


"...The rule is actually enforced by the N.B.A., which has no plans to change it. It was put in place in 2005 as part of the league’s collective bargaining agreement, after teams spent years investing in athletic but unproven teenagers who were jumping straight to the N.B.A. from high school. Some, like Kobe Bryant and Kevin Garnett, turned into stars. Others flopped.

"Technically, the rule does not force talented players like Kentucky’s Anthony Davis to go to college, but it states that they must be one year removed from their graduating high school class to be eligible for the N.B.A. draft. Academics have criticized the rule and the N.C.A.A. has complained, but neither had the power to make any changes. Even a former Kentucky president, Lee T. Todd Jr., has expressed uneasiness with the situation, one which can give players little incentive to attend class, let alone excel academically, after a certain point in the season."

"First Amendment rights group Media Coalition, which represents the Motion Picture Association of America, the Recording Industry Association of America, the Association of American Publishers and other related groups, says the bill is not only a violation of the First Amendment, but is so far-ranging as to be preposterous.


In a letter to the governor, the coalition said while government can criminalize speech "that rises to the level of harassment, and many states have laws that do so," Arizona's legislation:


... takes a law meant to address irritating phone calls and applies it to communication on web sites, blogs, listserves and other Internet communication. H.B. 2549 is not limited to a one to one conversation between two specific people. The communication does not need to be repetitive or even unwanted. There is no requirement that the recipient or subject of the speech actually feel offended, annoyed or scared. Nor does the legislation make clear that the communication must be intended to offend or annoy the reader, the subject or even any specific person."




“(Superintendent Colby) asked me three times if he could view my Facebook and I repeatedly said I was not OK with that,” Hester told WSBT.


In a letter to Hester from the Lewis Cass ISD Special Education Director, he wrote “…in the absence of you voluntarily granting Lewis Cass ISD administration access to you[r] Facebook page, we will assume the worst and act accordingly.


Hester is currently on unpaid leave, collecting workman's compensation while legally battling the school district. "I stand by it," Hester told WSTB News. "I did nothing wrong. And I would not, still to this day, let them in my Facebook.  And I don’t think it’s OK for an employer to ask you.”

Purpose of the Raspberry Pi


"The Raspberry Pi is a credit-card sized computer that plugs into a TV (or DVI monitor) and a keyboard, and can be used for "many of the things your desktop PC does, like spreadsheets, word-processing and games," says the foundation, a registered British charity started with the goal of getting kids thinking about programming — and not just consuming content — on computers. "This is a tiny bit of kit aimed at getting hackable technology into the hands of anyone who can afford" it, noted The Register."

Raspberry Pi: Cool!


The Raspberry Pi is a $25 computer that is powerful enough to run Quake 3, a pretty intense 3D video game. It plugs straight into a TV with an HDMI output and it's designed to be cheap enough that anyone can buy.

So why is the Raspberry Pi foundation, the organization behind this charming device, making the computers in the first place?

We spoke with Eben Upton, executive director of the Raspberry Pi foundation to find out why. Here's what we learned:

  • It's primarily intended for the education market. The whole idea was conceived as a way to get kids to learn how to manipulate and program computers earlier on.
  • The Raspberry Pi foundation wants to open-source the technology so "a company in China can produce a million computers" for developing countries and schools. The foundation expects third parties to start developing Raspberry Pi devices midway through 2012.
  • The multimedia performance of the Raspberry Pi is "substantially better" than the Tegra 3, a chip used in many modern smartphones, Upton said. The only smartphone that comes close to the Raspberry Pi's performance is the Galaxy S 2, he said.
  • They don't intend to make money off it. While you could easily turn something like this into a fully operational business, the Raspberry Pi foundation will remain a not-for-profit, Upton said.
  • Around 10,000 units should be available once or twice a month. There's an upper limit of about 100,000 that the Raspberry Pi foundation can produce in a year, though.

SpaceX poised to make history with space station docking


Hawthorne-based commercial space venture SpaceX is set to send its Dragon space capsule to dock with the $100-billion International Space Station -- a feat that's been accomplished only by the world's wealthiest nations.
NASA announced Friday that the private company, formally named Space Exploration Technologies Corp., will aim to launch its 18-story Falcon 9 rocket Feb. 7, pending completion of final safety reviews, testing and verification.
In a statement, SpaceX President Gwynne Shotwell said the mission "will mark a historic milestone in the future of spaceflight.”

Cagebreak!

A new study finds that rats will intentionally work to free a trapped pal.

A new study finds that rats will intentionally work to free a trapped pal.

Calling someone a "rat" is no compliment, but a new study shows that rats actually are empathetic and will altruistically lend a helping paw to a cage mate who is stuck in a trap.

Not only will rats frantically work to free their trapped cage mate; they will do so even when there's a tempting little pile of chocolate chips nearby, the study reveals. Instead of leaving their pal in the trap and selfishly gobbling the candy all by themselves, rats will free their cage mate and share the chocolate.

"To me that's absolutely stunning," says neurobiologist Peggy Mason of the University of Chicago. "The fact that the rat does that is really amazing."

Mason and her colleagues designed a series of experiments, described in the journal Science, to explore the evolutionary roots of empathy.

Scientists excited over hints of finding the elusive Higgs boson - latimes.com

Hundreds of researchers are sifting through data from CERN's Large Hadron Collider outside Geneva, which sends beams of protons hurtling toward one another at nearly the speed of light. They are hoping that some of the collisions produced telltale tracks of the Higgs boson — and thus provide a key piece of experimental confirmation of the Standard Model of particle physics, which describes how subatomic particles interact to form the basic building blocks of the universe.
