Quantum data lock promises leak-proof security


Quantum bit lock promises perfect security, even if someone cheats


Quantum cryptography is secure against intruders, since you can't intercept data in mid-flight without ruining it. The technology won't always stop leaks, however, which is why the University of Cambridge has developed a new protocol that keeps participants honest. The method combines the theories of both quantum physics and special relativity to preserve data in a locked state that isn't readable unless the sender provides a key; the laws of physics prevent anyone from decrypting the info beforehand. While we won't see any practical application of this quantum lock for a while, it could prove vital to financial traders and others who can't always trust their contacts.

(AP) — The Senate prepared to push major gay rights legislation past a first, big hurdle Monday as Democrats and a handful of Republicans united behind a bill to prohibit workplace discrimination against gay, bisexual and transgender Americans.

The legislation could win Senate passage by week's end, but its prospects in the Republican-majority House are dimmer.

Hours before Monday's vote, President Barack Obama issued a fresh plea for passage of the Employment Non-Discrimination Act, the first significant gay rights bill since Congress lifted the ban on gays serving openly in the military nearly three years ago.

"Americans ought to be judged by one thing only in their workplaces: their ability to get their jobs done," the president said in a message written for Huffingtonpost.com. "Does it make a difference if the firefighter who rescues you is gay — or the accountant who does your taxes or the mechanic who fixes your car?"

All 55 members of the Democratic majority and at least five Republicans were expected to vote to proceed with the bill, giving Majority Leader Harry Reid, D-Nev., the 60 votes necessary. Reid's Republican colleague in Nevada, Dean Heller, announced his support on Monday, saying that the measure "raises the federal standards to match what we have come to expect in Nevada, which is that discrimination must not be tolerated under any circumstance."

Opening Senate debate, Reid quoted slain gay rights leader Harvey Milk, who argued that freedom and individual rights shouldn't hinge on political deals and opinion polls.

The law, Reid said, would ensure that "all Americans regardless of where they live can go to work unafraid to be who they are." Sen. Tom Harkin, D-Iowa., called the measure another step forward in the country's progress.

The administration, in a strong statement of support, said passage of the bill was long overdue.

Current federal law prohibits discrimination on the basis of sex, race and national origin. But it doesn't stop an employer from firing or refusing to hire workers because they are gay, lesbian, bisexual or transgender. The bill would bar employers with 15 or more workers from using a person's sexual orientation or gender identity as the basis for making employment decisions, including hiring, firing, compensation or promotion.

Possible passage of the bill by week's end would cap a 17-year quest to secure Senate support for the anti-bias measure that failed by one vote in 1996, the same year Congress passed and President Bill Clinton signed the Defense of Marriage Act. That law required the federal government to refuse to recognize same-sex marriages.

Today Americans have shown increasing support for same-sex marriage, now legal in 14 states and the District of Columbia. The Supreme Court in June affirmed gay marriage and granted federal benefits to legally married same-sex couples.

Meanwhile, in Maine on Monday, six-term Democratic Rep. Mike Michaud, who is running for governor, said that he is gay.

"That may seem like a big announcement to some people. For me, it's just a part of who I am, as much as being a third-generation mill worker or a lifelong Mainer. One thing I do know is that it has nothing to do with my ability to lead the state of Maine," Michaud wrote in an op-ed article.

The anti-discrimination bill faces strong opposition from conservative groups — Heritage Action and the Faith and Freedom Coalition said the vote will be part of their legislative scorecard on lawmakers. More to its immediate prospects, the legislation is opposed by Speaker John Boehner, R-Ohio, and it's unclear whether the House will even vote on the measure.

Reiterating Boehner's longstanding opposition, spokesman Michael Steel said Monday that Boehner "believes this legislation will increase frivolous litigation and cost American jobs, especially small business jobs."

Besides Heller, four other Republican senators are backing the legislation — Susan Collins of Maine, Mark Kirk of Illinois, Orrin Hatch of Utah and Lisa Murkowski of Alaska — and proponents expect a few others to support it.

Chad Griffin, president of the Human Rights Campaign, the largest gay and lesbian advocacy group, contrasted Heller's backing with Boehner's opposition.

"The speaker, of all people, should certainly know what it's like to go to work every day afraid of being fired," Griffin said, a reference to the unsuccessful, tea party-backed challenge to Boehner earlier this year.

Twenty-two states and the District of Columbia have approved laws banning workplace discrimination on the basis of sexual orientation, and 17 of those also prohibit employers from discriminating based on gender identity.

About 88 percent of Fortune 500 companies have adopted nondiscrimination policies that include sexual orientation, according to the Human Rights Campaign. About 57 percent of those companies include gender identity.

The U.S. Chamber of Commerce remains neutral on the bill, a spokeswoman said Monday.

Drew Hammill, a spokesman for House Democratic Leader Nancy Pelosi, said it was disappointing that Boehner may not bring the measure to a vote. "When the Senate passes this legislation, all options will be on the table in order to advance this critical legislation in the House," Hammill said.

At the White House, spokesman Jay Carney sidestepped questions about whether Obama would consider issuing an executive order on workplace discrimination if Congress refused to act. Gay rights groups have criticized Obama for refusing to take that step, which would affect employees who work for federal contractors.

"We're focused on getting ENDA through Congress," Carney said, using the acronym for the workplace discrimination bill.

How can you tell if a breast tumor is malignant? This isn't a question that ultrasound and X-rays, or even magnetic resonance scans, can answer alone. Doctors must often extract tissue samples from an affected area with a fine needle for detailed examination. This sort of biopsy is often undertaken with the help of ultrasound, with doctors observing a screen for needle guidance. Unfortunately, around 30 percent of all tumors are invisible to ultrasound. In some cases, magnetic resonance imaging (MRI) is used to ensure correct needle insertion. This process involves two steps: the imaging itself, which takes place inside the MRI scanner, and the insertion of the biopsy needle, for which the patient must be removed from the machine to insert the needle accurately. This process is often repeated several times before the sample is finally taken. This ex-hausts patients and is also costly, because the procedure occupies the MRI scanner for a significant period.


In the joint MARIUS project (Magnetic Resonance Imaging Using Ultrasound systems and processes for multimodal MR imaging), experts from both the Fraunhofer Institute for Biomedical Engineering IBMT in St. Ingbert and the Fraunhofer Institute for Medical Image Computing MEVIS in Bremen are working together towards a quicker and gentler alternative.


Combining imaging techniques intelligently


The new technique would require just one scan of the patient's entire chest at the beginning of the procedure, meaning that the patient only has to enter the scanner once. The subsequent biopsy is guided by ultrasound; the system would transform the initial MRI scan and accurately render it on screen. Doctors would have both the live ultrasound scan and a corresponding MR image available to guide the biopsy needle and display exactly where the tumor is located.


The biggest challenge is that the MRI is performed with the patient lying prone, while during the biopsy she lies on her back. This change of position alters the shape of the patient's breast and shifts the position of the tumor significantly. To track these changes accurately, researchers have applied a clever trick: While the patient is in the MRI chamber during the scan, ultrasound probes, which resemble ECG electrodes, are attached to the patient's skin to provide a succession of ultrasound images. This produces two comparable sets of data from two separate imaging techniques.


When the patient undergoes a biopsy in another examination room, the ultrasound probes remain attached and continually record volume data and track the changes to the shape of the breast. Special algorithms analyze these changes and update the MRI scan accordingly. The MR image changes analogously to the ultrasound scan. When the the biopsy needle is inserted into the breast tissue, the doctor can see the reconciled MRI scan along with the ultrasound image on the screen, greatly improving the accuracy of needle guidance towards the tumor.


Ultrasound equipment suitable for use in an MRI Scanner


To realize this vision, Fraunhofer researchers are developing a range of new components. "We're currently working on an ultrasound device that can be used within an MRI scanner," says IBMT project manager Steffen Tretbar. "These scanners generate strong magnetic fields, and the ultrasound device must work reliably without affecting the MRI scan." Ultrasound probes that can be attached to the body to provide 3D ultrasound imaging are also being developed by the team as part of the project.


The software developed for the technique is also completely new. "We're developing a way to track movements in real time by means of ultrasound tracking," explains MEVIS project manager Matthias Gnther. "This recognizes distended structures in the ultrasound images and tracks their movement. We also need to collate a wide range of sensor data in real time." Some of the sensors gather data about the position and orientation of the attached ultrasound probes while others track the position of the patient.


The team will showcase the entire concept and an initial demonstrator of the technology in November at the MEDICA 2013 trade fair in Dsseldorf at the joint Fraunhofer booth (Hall 10, Booth F05). The next version is set to be completed next year. Whereas the IBMT team is developing the hardware and new ultrasound techniques, the MEVIS working group is concentrating on the software.


The primary objective of MARIUS is to develop ultrasound tracking to aid breast biopsies. Nevertheless, the developed components could also be used in other applications. For instance, the MARIUS system and its movement-tracking software could allow slow imaging techniques such as MRI or positron emission tomography (PET) to accurately track the movements of organs that shift even when a patient is lying still. Aside from the liver and the kidneys, which change shape and position during breathing, this includes the heart, whose contractions also cause motion. Thanks to a technique applied to reconstruct the image, the heart would appear well defined on MRI scans instead of blurred. The jointly developed technology could also be applied to treatments that use particle or X-ray beams. For tumors located in or on a moving organ, the new technology could target the rays so that they follow the movement.These beams could hit the tumor with more precision than currently possible and reduce damage to healthy surrounding tissue.

(AP) — Google is investing 450 million euros ($608 million) to expand a data center in southern Finland as part of Europe-wide development plans totaling hundreds of millions of euros.

The investment comes on top of the 350 million euros it spent on converting an old paper mill, bought from paper maker Stora Enso in 2009, into one of its centers serving customers in Europe and worldwide. It started operations in 2011, and currently employs some 125 people in Hamina, 150 kilometers (95 miles) east of Helsinki.

Google Inc. says the Hamina center is one of its most advanced and efficient, with a high-tech cooling system that uses seawater from the Baltic Sea to reduce energy usage and help keep computers running smoothly. In 2015, the plant will be primarily powered by wind energy and there are plans to meet future energy needs with "100% renewable energy."

The company says the expansion will employ up to 800 engineering and construction workers at the plant and that new, permanent jobs will be created once the extension opens.

"This investment underlines our commitment to working to help Finland take advantage of all the economic benefits from the Internet," Google's Finland manager Anni Ronkainen said. "As demand grows for our products, from YouTube to Gmail, we're investing hundreds of millions of euros in expanding our European data centers."

Finnish Prime Minister Jyrki Katainen, who attended the announcement in Hamina, welcomed the investment.

"Finland needs more foreign direct investments in order to enhance our economy, growth and employment," Katainen said. "Google's investment decision is important for us and we welcome it warmly."

Google has 19 data centers worldwide, with 70 offices in more than 40 countries employing some 30,000 people.

AP-CNBC poll: Twitter faces skeptical investors

(AP) — Twitter faces skepticism from potential investors and the broader public ahead of its initial public offering, according to an Associated Press-CNBC poll released Monday.

Some 36 percent of Americans say buying stock in the 7-year-old short messaging service would be a good investment, while 47 percent disagree. Last May, ahead of Facebook's IPO, 51 percent of Americans said Facebook Inc. would be a good investment. Just 31 percent didn't agree.

Twitter plans to make its Wall Street debut this week and surprisingly, 52 percent of people ages 18 to 34 say investing in the company's stock is not a good idea.

Twitter Inc. will begin trading on the New York Stock Exchange on Thursday morning after setting a price for its IPO sometime Wednesday evening. As it stands, the San Francisco-based company plans to raise as much as $1.6 billion in the process. The transaction values Twitter at as much as $12.5 billion. That's little more than one-eighth of Facebook's roughly $104 billion market value when it went public.

Twitter has not turned a profit since its launch, but its future depends on advertisements as a primary source of income. The company mainly sells three types of ads: promoted tweets, promoted accounts and promoted trends. A company like Starbucks, for instance, can pay Twitter to promote a single tweet or it can pay the company to ask users to follow its account.

It does not bode well that more than half of Twitter users say they have not noticed advertising. Among the 42 percent of users who did notice, 31 percent say they've clicked on or followed one of the promoted items in question.

Among the poll's other key findings:

— One in 5 Americans say they have a Twitter account. One in 10, meanwhile, looks at Twitter feeds but doesn't have an account of their own.

— Nearly a quarter of Twitter account holders send tweets at least once a day, while 29 percent say they never do. More account holders say they read others' tweets daily, 35 percent.

— About 30 percent of Twitter users say they have used the service to register complaints about a product or service or when they are looking for information about services or products.

— Twitter has billed itself as the place for public, real-time conversations, but only 16 percent of users say they turn to Twitter frequently for breaking news. That said, 44 percent of users do so at least some of the time.

— Just 19 percent of respondents say they have a "favorable" view of Twitter, while 47 percent feel the same way about Facebook.

— A sizable share of Americans aren't familiar with Twitter or don't know what to make of it: 9 percent have never heard of it and another 12 percent say they just don't know how they feel about it.

—Just 35 percent of Americans say they think Twitter will be a successful company in five years. More, 49 percent, think Facebook will be successful in five years.

The Associated Press-CNBC telephone poll was conducted Oct. 25 to 27 by GfK Roper Public Affairs and Corporate Communications among 1,006 U.S. adults. The results have a margin of error of plus or minus 3 percentage points. According to Twitter, 77 percent of its 232 million monthly visitors are outside of the U.S.

Biden: Whole nation looking to Virginia gov's race


ANNANDALE, Va. (AP) — Vice President Joe Biden says the entire nation is looking to the governor's race in Virginia to see the new face of progress in America.

Biden is campaigning with Democrat Terry McAuliffe in the Washington suburbs a day before Election Day.

Biden says McAuliffe's opponent, Republican Ken Cuccinelli, is the loudest voice in America against women's access to health care. He's painting Cuccinelli as part of a tea party faction that's turning back progress.

Biden says if Cuccinelli wins, Virginia will have to give companies stipends to locate in the state because corporations will be so turned off by Cuccinelli's policies.

He's praising McAuliffe as smart, tough and rooted in middle-class values.

Cuccinelli is campaigning Monday with Sen. Marco Rubio of Florida and former Rep. Ron Paul of Texas.
