Library of Congress digs in to full archive of 170 billion tweets

Label:


The U.S. Library of Congress said today that it has completed a process of collecting a full, ongoing stream of tweets, and that it has begun work to archive and organize more than 170 billion tweets.




Under an agreement struck between the government institution and Twitter in 2010, the microblogging company is providing the Library of Congress with a full stream of all public tweets, starting with 21 billion generated from between 2006 and April 2010, and now supplemented with about 150 billion more posted since then.


In an announcement about the status of the project today, the library wrote that:


Twitter is a new kind of collection for the Library of Congress but an important one to its mission. As society turns to social media as a primary method of communication and creative expression, social media is supplementing, and in some cases supplanting, letters, journals, serial publications, and other sources routinely collected by research libraries.


Though the Library has been building and stabilizing the archive and has not yet offered researchers access, we have nevertheless received approximately 400 inquiries from researchers all over the world. Some broad topics of interest expressed by researchers run from patterns in the rise of citizen journalism and elected officials' communications to tracking vaccination rates and predicting stock market activity.


The Library of Congress isn't entirely clear how the ongoing archive will be utilized, but it has issued a white paper (PDF) outlining the project.


This project, of course, is different than Twitter's recently announced initiative to make every user's full tweet history available to them. That effort is under way, though only some users have been given access to date.


Interestingly, the Library of Congress reported in the white paper that its two full copies of the entire archive of 170 billion tweets comprise about 133 Terabytes of data. Each tweet, the library wrote, contains about 50 accompanying metadata fields.

Quadruple Amputee Gets Two New Hands on Life

Label:












It's the simplest thing, the grasp of one hand in another. But Lindsay Ess will never see it that way, because her hands once belonged to someone else.


Growing up in Texas and Virginia, Lindsay, 29, was always one of the pretty girls. She went to college, did some modeling and started building a career in fashion, with an eye on producing fashion shows.


Then she lost her hands and feet.


Watch the full show in a special edition of "Nightline," "To Hold Again," TONIGHT at 11:35 p.m. ET on ABC


When she was 24 years old, Lindsay had just graduated from Virginia Commonwealth University's well-regarded fashion program when she developed a blockage in her small intestine from Crohn's Disease. After having surgery to correct the problem, an infection took over and shut down her entire body. To save her life, doctors put her in a medically-induced coma. When she came out of the coma a month later, still in a haze, Lindsay said she knew something was wrong with her hands and feet.


"I would look down and I would see black, almost like a body that had decomposed," she said.


The infection had turned her extremities into dead tissue. Still sedated, Lindsay said she didn't realize what that meant at first.










"There was a period of time where they didn't tell me that they had to amputate, but somebody from the staff said, 'Oh honey, you know what they are going to do to your hands, right?' That's when I knew," she said.


After having her hands and feet amputated, Lindsay adapted. She learned how to drink from a cup, brush her teeth and even text on her cellphone with her arms, which were amputated just below the elbow.


"The most common questions I get are, 'How do you type,'" she said. "It's just like chicken-pecking."

Despite her progress, Lindsay said she faced challenges being independent. Her mother, Judith Aronson, basically moved back into her daughter's life to provide basic care, including bathing, dressing and feeding. Having also lost her feet, Lindsay needed her mother to help put on her prosthetic legs.


"I've accepted the fact that my feet are gone, that's acceptable to me," Lindsay said. "My hands [are] not. It's still not. In my dreams I always have my hands."


Through her amputation recovery, Lindsay discovered a lot of things about herself, including that she felt better emotionally by not focusing on the life that was gone and how much she hated needing so much help but that she also truly depends on it.


"I'm such an independent person," she said. "But I'm also grateful that I have a mother like that, because what could I do?"


Lindsay said she found that her prosthetic arms were a struggle.


"These prosthetics are s---," she said. "I can't do anything with them. I can't do anything behind my head. They are heavy. They are made for men. They are claws, they are not feminine whatsoever."


For the next couple of years, Lindsay exercised diligently as part of the commitment she made to qualify for a hand transplant, which required her to be in shape. But the tough young woman now said she saw her body in a different way now.

Unique meteorite hints Mars stayed moist for longer

Label:







































A scorched rock bought in Morocco turned out to be a diamond in the rough. The unusual meteorite may be the first sample of the Red Planet's crust ever to hit Earth, and it suggests that Mars held on to its water for longer than we thought.












The meteorite, dubbed Northwest Africa (NWA) 7034, is strikingly different from the 111 previously discovered Martian meteorites. "You could look at meteorites for the rest of your life and not find another one like this," says Carl Agee of the University of New Mexico in Albuquerque, who was part of a team that has recently analysed NWA 7034. "This is in its own new group."













The most distinctive difference is its mineral content. Previously found meteorites had unearthly oxygen isotopes that marked them as being from another planet, and their volcanic origin made Mars the most likely culprit. But compared to these meteorites, surface rocks studied by Martian rovers and orbiters are much richer in light metals such as potassium and sodium. This suggests the known meteorites came from deeper inside the Red Planet.












"We're watching data coming back from Mars, and everything that comes back doesn't look like the Martian meteorites we have in our collections," says Munir Humayun of Florida State University in Tallahassee, who was not involved in the new study. "That's kind of a bummer."











By contrast, NWA 7034's chemistry closely resembles the rock and soil studied by NASA's Spirit rover. Preliminary measurements from the Curiosity rover, which landed in August 2012, suggest its landing site also has a similar composition.












Drying era













"Finally, it looks as if we have a sample that is very similar to the rocks that the rovers are seeing," Agee says. What's more, the Moroccan meteorite may come from a period in Mars' history when the planet was drying out.











Mars is thought to have once been much warmer, wetter and more hospitable to life. Then it morphed into the dry, cold desert we see today. The oldest known Mars meteorite, called the Allan Hills meteorite, is 4.5 billion years old. The other 110 meteorites are much younger – 1.5 billion years old at most – and formed after Mars is thought to have lost its water.













NWA 7034 is 2.1 billion years old, making it the first meteorite that may hail from the transitional era. Intriguingly, it has as much as 30 times more water than previous meteorites locked up in its minerals. "It opens our mind to the possibility that climate change on Mars was more gradual," Agee says. "Maybe it didn't lose its water early on."











Hot deal













The 319.8-gram rock found its way to Agee's lab via an amateur collector named Jay Piatek. He bought it for what turned out to be a knock-down price from a Moroccan meteorite dealer, who recognised its scorched exterior as a sign that it fell from space. "It didn't look like a Martian meteorite, so it didn't have the Martian meteorite value at the time," Agee says, adding that Mars rock can go for $500 to $1000 per gram.












Piatek brought the rock to Agee's lab to find out what it was. "Honestly, I had never seen anything like it. I was baffled, initially," Agee says. "Now, about a year and a half after the first time I set eyes on this thing, we are convinced that it is Martian, a new type, and has important implications for understanding the history of Mars."












Humayun says the results so far are exciting, and that the rock's carbon content could also yield valuable insights once other researchers get their hands on it.












"What's the most exciting thing you would want to do with a rock that comes from the near surface of Mars, especially one that seems to be loaded with water?" he asks. "I would say, what about life?" Agee and colleagues found organic matter in the meteorite, he says, but it will take more work to determine whether it was of Martian or terrestrial origin.












If it's Martian, "that would spark a lot of excitement", he says.

Teen boasts of drunken driving on Facebook, arrested

Label:


Cox-Brown's Facebook page. The boast has been removed.



(Credit:

It has now been firmly established -- by Randi Zuckerberg, no less -- that Facebook is the home of human decency.


How is it possible, then, that 18-year-old Jacob Cox-Brown of Astoria, Ore., did not receive the message?


For, according to KGW.com, Cox-Brown had the indecent temerity to post this to his Facebook page: "Drivin drunk... classsic ;) but to whoever's vehicle i hit i am sorry. :P."


This was, indeed, a classsic (sic) example of misbegotten sharing.


For police -- who had concluded that not one but two vehicles had been struck by an unknown driver -- now concluded that the driver was Jacob Cox-Brown.


How did they manage this? By the saddest reality of all. Two of Cox-Brown's alleged friends reportedly contacted the law in order, one imagines, to restore human decency.



More Technically Incorrect



The police issued a press release that read: "Astoria Police have an active social media presence. It was a private Facebook message to one of our officers that got this case moving, though. When you post...on Facebook, you have to figure that it is not going to stay private long."


No, not long at all, as Randi Zuckerberg can attest.


Cox-Brown has been charged with two counts of failing to perform the duties of a driver. These, presumably, include not hitting other vehicles.


While Randi Zuckerberg railed that you can't trust the friends of friends, Cox-Brown now seems to have realized that you can't even trust your friends.


At least those who claim to be your friends on Facebook.

Pictures We Love: Best of 2012

Powder-splattered, and powder-splattering, runners cross the finish line of The Color Run 5K in Irvine, California, on April 22. Each kilometer (0.6 mile) of the event features a color-pelting station dedicated to a single hue, culminating in the Pollock-esque riot at kilometer 5.

The "magical color dust" is completely safe, organizers say, though they admit it's "surprisingly high in calories and leaves a chalky aftertaste."

Ex-USC Player: Painkiller Injections Caused Heart Attack

Label:












Despite stated label risks of possible fatal heart attack, stroke or organ failure, college football players across the country are still being given injections of a powerful painkiller on game days so they can play while injured, an ABC News investigation has found.


The drug, a generic version of Toradol, is recommended for the short-term treatment of post-operative pain in hospitals but has increasingly been used in college and professional sports, and its use is not monitored by the NCAA, the governing body of college sports.


Only two of the country's top football programs, Oklahoma and the University of Nebraska, reported to ABC News that they have limited or stopped the use of the drug in the wake of growing concern about its risks.


Which Top-Ranked College Football Teams Use Toradol?


Oklahoma said it stopped using the painkillers in 2012 after using them repeatedly in 2010 and 2011.


Nebraska said its doctors now restrict its use.


SEND TIPS About Painkiller Use in College Sports to Our Tipline


"While team physicians reserve the option to use injectable Toradol, it is rarely prescribed, and its use has been avoided this season following reports of heightened concern of potential adverse effects," Nebraska said in a statement to ABC News.

Despite Risks, College Football Still Uses Powerful Painkiller Watch Video





The top two college football programs, Notre Dame and Alabama, refused to answer questions from ABC News about the painkiller. They play for the national college championship on Jan. 7.


Controversy surrounding the drug has grown this year following claims by former USC lineman Armond Armstead that he suffered a heart attack after the 2010 season, at age 20, following shots of generic Toradol administered over the course of the season by the team doctor and USC personnel.


"I thought, you know, can't be me, you know? This doesn't happen to kids like me," Armstead told ABC News.


The manufacturers' warning label for generic Toradol (ketorolac tromethamine) says the drug is not intended for prolonged periods or for chronic pain and cites gastrointestinal bleeding and kidney failure as possible side effects of the drug.


In addition, like other drugs in its class, the generic Toradol label warns "may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction (heart attack), and stroke, which can be fatal."


"This risk may increase with duration of use," the so-called black box warning reads.


In a lawsuit against the school and the doctor, Dr. James Tibone, Armstead claims the school ignored the stated risks of the drug and never told him about them.


"He was a race horse, a prize race horse that needed to be on that field no matter what," said Armstead's mother Christa. "Whether that was a risk to him or not."


Armstead says he and many other USC players would receive injections of what was known only as "the shot" in a specific training room before big games and again at half-time.


"No discussion, just go in. He would give the shot and I would be on my way," Armstead told ABC News.


Armstead said the shot made him feel "super human" despite severe ankle, and later shoulder pain, and that without it, he never could have played in big USC games against Notre Dame and UCLA.


"You can't feel any pain, you just feel amazing," the former star player said.


USC declined to comment on Armstead's claims, or the use of Toradol to treat Trojan players.


An ABC News crew and reporter were ordered off the practice field when they tried to question USC coach Lane Kiffin about the use of the painkiller. USC says the ABC News crew was told to leave because they had not submitted the appropriate paperwork in advance to attend the practice session.

One killed as cyclone hits New Caledonia

Label:





NOUMEA: One man was killed and another was missing after Cyclone Freda hit New Caledonia, as landslides blocked roads and high winds downed power lines, officials in the French Pacific territory said on Thursday.

Wind gusts had weakened to 90 kilometres per hour (60 miles per hour) as it moved towards the east Caledonian island of Mare, after hitting the Solomon Islands earlier this week as a destructive storm with gusts reaching 231 kph.

High commissioner Albert Dupuy told reporters in the capital Noumea that one man had drowned in high seas whipped up by Freda, while an 18-year-old male was missing after attempting to cross a swollen river.

Some 3,200 people were without power, Dupuy said, adding that multiple roadways were blocked by landslides or flooding.

The storm was moving eastward at 30 kph and set to leave the New Caledonian region over the next 48 hours, officials said.
