Evernote resets passwords after data breach

Evernote, a Web-based note-sharing service, said it was resetting the passwords of its 50 million users because hackers managed to breach its computer network and access some user names, email addresses and encrypted passwords.

Evernote spokeswoman Ronda Scott said via email on Saturday that the attack "follows a similar pattern" to other cyber attacks on Internet-based companies in recent weeks, but she did not elaborate.

"In our security investigation, we have found no evidence that any of the content you store in Evernote was accessed, changed or lost," the company said on its website. "We also have no evidence that any payment information for Evernote Premium or Evernote Business customers was accessed."

Scott declined to say how many accounts had been exposed or whether it might be possible for the hackers to unscramble encrypted passwords.

A series of technology companies including Facebook, Apple, Microsoft and Twitter have recently disclosed cyber attacks. In the majority of those cases, the companies said that the unknown hackers exploited a bug in Java software and that no user information was compromised.

Twitter is the only major Internet company that has recently reported its user information was exposed to hackers. On Feb. 1, Twitter reset passwords for 250,000 accounts whose encrypted passwords may have been accessed.

Scott said Evernote believed that the hackers did not exploit a bug in Java when they broke into the company's system.

Evernote is a privately held company whose major investors include Meritech Capital, CBC Capital, Sequoia Capital, Morgenthaler Ventures and DOCOMO Capital.

Pregnancy permanently changes foot size

Mar. 1, 2013 ? A new University of Iowa study confirms what many women have long suspected -- that pregnancy permanently changes the size and shape of a woman's feet.

Flat feet are a common problem for pregnant women. The arch of the foot flattens out, possibly due to the extra weight and increased looseness (laxity) of the joints associated with pregnancy. The new study, published in the March issue of the American Journal of Physical Medicine & Rehabilitation, suggests that this loss of arch height is permanent.

"I had heard women reporting changes in their shoe size with pregnancy, but found nothing about that in medical journals or textbooks," says Neil Segal, M.D., UI associate professor of orthopaedics and rehabilitation. "In order to study this more scientifically, we measured women's feet at the beginning of their pregnancy and five months after delivery. We found that pregnancy does indeed lead to permanent changes in the feet."

The UI study followed 49 pregnant women and collected static and dynamic arch measurements during the first trimester of pregnancy and again about five months after childbirth. The researchers found that for about 60 to 70 percent of the women in the study, their feet became longer and wider.

Specifically, the study showed that, on average, arch height and measures of arch rigidity decreased significantly comparing early pregnancy with five months after childbirth, causing corresponding increases in foot length (between 2 and 10 mm) and arch drop. However, no significant change in the distribution of foot pressure was detected. The study also suggested that first pregnancies may account for most of the observed changes, while second, third, or higher pregnancies may not further alter foot structure.

"We know that women, and especially women who have had children, are disproportionately affected by musculoskeletal disorders," says Segal, who also is an associate professor of radiology and epidemiology, and director of the Clinical Osteoarthritis Research Program. "It is possible that these foot changes that occur during pregnancy may help explain why, in comparison with men, women are at higher risk for pain or arthritis in their feet, knees, hips and spines."

Segal plans to conduct follow-up studies to assess whether these foot changes lead to health problems, like arthritis, later in life. He also is conducting studies of how women's musculoskeletal health can be protected during pregnancy.

In addition to Segal, the research team included Elizabeth Boyer; Patricia Teran-Yengle; Natalie Glass; Howard Hillstrom; and John Yack. The study was funded in part by grants from the American Geriatrics Society and the National Institute on Aging. The research team can be contacted at 319-335-7900.

Scientists discover new belt of radiation around Earth

NASA's twin Van Allen space probes detected a previously unknown temporary ring of high energy particles around our planet.?

By Charles Q. Choi,?SPACE.com / February 28, 2013

Two giant swaths of radiation, known as the Van Allen Belts, surrounding Earth were discovered in 1958. In 2012, observations from the Van Allen Probes showed that a third belt can sometimes appear. The radiation is shown here in yellow, with green representing the spaces between the belts.

A ring of radiation previously unknown to science fleetingly surrounded Earth last year before being virtually annihilated by a powerful interplanetary shock wave, scientists say.

NASA's twin Van Allen space probes, which are studying the?Earth's radiation belts, made the cosmic find. The surprising discovery ? a new, albeit temporary, radiation belt around Earth ? reveals how much remains unknown about outer space, even those regions closest to the planet, researchers added.

After humanity began exploring space, the first major find made there were the?Van Allen radiation belts, zones of magnetically trapped, highly energetic charged particles first discovered in 1958.

"They were something we thought we mostly understood by now, the first discovery of the Space Age," said lead study author Daniel Baker, a space scientist at the University of Colorado.

These belts were believed to consist of two rings: an inner zone made up of both high-energy electrons and very energetic positive ions that remains stable in intensity over the course of years to decades; and an outer zone comprised mostly of high-energy electrons whose intensity swings over the course of hours to days depending primarily on the influence from the solar wind, the flood of radiation streaming from the sun.

The discovery of a temporary new radiation belt now has scientists reviewing the Van Allen radiation belt models to understand how it occurred.

Radiation rings around Earth

The giant amounts of radiation the Van Allen belts generate can pose serious risks for satellites. To learn more about them, NASA launched twin spacecraft, the Van Allen probes, in the summer of 2012.

The satellites were armed with a host of sensors to thoroughly analyze the plasma, energetic particles, magnetic fields and plasma waves in these belts with unprecedented sensitivity and resolution.

Unexpectedly, the probes revealed a new radiation belt surrounding Earth, a third one made of super-high-energy electrons embedded in the outer Van Allen belt about 11,900 to 13,900 miles (19,100 to 22,300 kilometers) above the planet's surface. This stable ring of?space radiation?apparently formed on Sept. 2? and lasted for more than four weeks.

"The feature was so surprising, I initially foolishly thought the instruments on the probes weren't working properly, but I soon realized the lab had built such wonderful instruments that there wasn't anything wrong with them, so what we saw must be true," Baker said.

This newfound radiation belt then abruptly and almost completely disappeared on Oct. 1. It was apparently disrupted by an interplanetary shock wave caused by a spike in solar wind speeds.

"More than five decades after the original discovery of these radiation belts, you can still find new unexpected things there," Baker said. "It's a delight to be able to find new things in an old domain. We now need to re-evaluate them thoroughly both theoretically and observationally."

A radiation mystery

It remains uncertain how this temporary radiation belt arose. Van Allen mission scientists suspect it was likely created by the?solar wind?tearing away the outer Van Allen belt.

"It looks like its existence may have been bookended by solar disturbances," Baker said.

Future study of the Van Allen belts can reveal if such temporary rings of radiation are common or rare.

"Do these occur frequently, or did we get lucky and see a very rare circumstance that happens only once in a while?" Baker said. "And what other unusual revelations might come now that we are really looking at these radiation belts with new, modern tools?"

The scientists detailed their findings online Feb. 28 in the journal Science.

Dale Robertson, actor in U.S. westerns, dies at 89

LOS ANGELES (Reuters) - Dale Robertson, the star of scores of Hollywood Westerns in the 1950s and 1960s, has died at the age of 89 in Southern California, Scripps Memorial Hospital in La Jolla said on Thursday.

Robertson, who was best known for his role of special agent Jim Hardie in the NBC television series "Tales of Wells Fargo" from 1957-1962, died on Tuesday, the hospital said.

The "Sitting Bull" star had been in poor health for about two years and had a cancer diagnosis last week, his niece, Nancy Love Robertson, told The Oklahoman newspaper.

Born Dayle Lymoine Robertson in Harrah, Oklahoma, in 1923, the actor attracted the attention of Hollywood agents after a Los Angeles photographer posted his photo in a display window.

Robertson, who served in Europe and Africa during World War Two, starred in 60 films and television shows over his five-decades acting career, starting out with roles in 1950s Westerns such as "Devil's Canyon" and "Dakota Incident."

The actor was inducted in 1983 into the National Cowboy and Western Heritage Museum's Western Performers Gallery in Oklahoma City, alongside some of Hollywood's most famous on-screen cowboys including John Wayne and Roy Rogers.

Robertson is survived by his wife, Susan, and two daughters.

Companies struggle to popularize mobile money

(AP) ? Mobile money may seem like a hot concept, but consumers aren't warming to it.

At the world's largest cellphone trade show, here in Barcelona this week, the 70,000 attendees are encouraged to use their cellphones ?instead their keycards? to get past the turnstiles at the door. But very few people took the chance to do that. The process of setting up the phone to act as a keycard proved too much of a hassle.

It's a poor omen for an industry that's eager to have the cellphone replace both tickets and credit cards. Companies are building chips antennas into phones that let the gadgets interact with "tap to pay" terminals and other devices equipped with short-range sensors, like subway turnstiles. But getting the technology to do something useful and convincing people to adopt it is a slow process.

To make a payment in a store with your cellphone, "you need a lot of things to align," said Reed Peterson, who heads the Near-Field Communications initiative for the GSM Association, a global trade group for the wireless industry. The phone needs to be properly equipped with NFC hardware and software; the store needs to have the proper equipment and training. The phone company needs to support the transaction, and banks and payment processors need to be in on it.

Some of these things have fallen into place, Peterson said, but the network of commercial agreements that supports these payments needs to expand. And consumer demand remains elusive.

"I want to get to the point where the consumer goes into the store and says 'Show me only the phones that have NFC'," Peterson said.

Today, a buyer is quite likely to go into a store and ask for an iPhone, and that's an obstacle to NFC adoption. Apple Inc. is the lone holdout among major smartphone makers, and hasn't built NFC into any of its devices yet.

Visa, the global payments network, announced a coup at the show: it has struck a deal with Samsung Electronics to take charge of the "secure element" in the next flagship phone from the South Korean company. The Galaxy S IV is expected to be launched at an event in New York on Mar. 14, though the name has not been confirmed.

The "secure element" is sort of like a safe inside the phone. Whoever controls access to it decides which credit cards, transit passes or other verified "documents" the phone can store. A bank that wants to let customers use their Samsung smartphones as virtual credit cards will have to go through Visa.

Control of the secure element is a crucial battleground for NFC. The GSMA, which is dominated by cellphone carriers, advocates putting the secure element not in the phone itself, but in the subscriber identity module, or SIM card, which plugs into the phone to identify the user and supply a phone number to the network. SIM cards are issued and controlled by the carriers who would like to be the ones in control of the secure element.

While Visa, phone companies and Google (which has its own payment initiative) duel over the secure element, eBay Inc.'s PayPal is wondering what all the fuss is about. The online payment network thinks NFC is a lot more trouble than it's worth. The company isn't afraid to say so at the wireless industry tradeshow.

"If you want to change something, you have to solve problems that people have in everyday life," said David Marcus, the president of PayPal. "It's not like everyone is thinking 'Oh, I wish someone came up with something better'" than paper money and credit cards.

PayPal is putting a lot of effort into making cellphones central to the way we shop, but is focusing on the shopping experience itself, rather than payments. The company's ideal vision for buying a cup of coffee: You pull out your phone on the way to the store, fire up PayPal's app to order your double-skim latte and pay for it in advance. When you arrive at the counter, the barista has your picture and your coffee, and gives it to you right away. Then you're out the door.

Thirty years ago, Marcus said, store clerks knew the people in their neighborhood and greeted them by name.

"We think with this technology, we could recreate that personal connection," he said. "We feel this is going to leapfrog the efforts of NFC."
