Kindle iOS app gets a slew of new features for the blind and visually impaired

The latest upgrade to the iPhone and iPad version of Amazon's Kindle reading app brings a bunch of new features aimed at blind and visually impaired users. At the top of the list is the ability to read aloud 1.8 million Kindle Store titles, with help from Apple's VoiceOver technology. The update also brings better library and book navigation and search, as well as features like notes, highlights, bookmarks, font size, background color and brightness. Standard Kindle features like X-Ray, End Actions and sharing via Facebook and Twitter are also made more accessible through the update. Amazon's promised a similar update for non-iOS versions of the app at some point in the future -- in the meantime, a full list of new features can be found in a press release after the break.

(AP) ? A Vermont woman revealed her new face Wednesday, six years after her ex-husband disfigured her by dousing her with industrial-strength lye, and said she went through "what some may call hell" but has found a way to be happy.

Carmen Blandin Tarleton of Thetford had face transplant surgery at Boston's Brigham and Women's Hospital in February and spoke publicly for the first time at a news conference at the hospital Wednesday.

"I'm now in a better place, mentally and emotionally, than I ever could have imagined six years ago," Tarleton said. "I want to share my experience with others, so they may find that strength inside themselves to escape their own pain."

In 2007, the 44-year-old mother of two was attacked by her now ex-husband Herbert Rodgers, who believed she was seeing another man. Police say he went to the house looking for that man, then went into a fury directed toward Tarleton, striking her with a bat and pouring lye from a squeeze bottle onto her face.

When police arrived, Tarleton was trying to crawl into a shower to wash away the chemical, which had already distorted her face.

In 2009, Rodgers pleaded guilty to maiming Tarleton in exchange for a prison sentence of at least 30 years.

The hospital said that during the face transplant surgery, more than 30 surgeons, anesthesiologists and nurses worked for more than 15 hours to replace her skin, muscles, tendons and nerves.

The face donor was a Williamstown, Mass., woman, Cheryl Denelli Righter, who died of a sudden stroke, a hospital spokeswoman said.

Righter's daughter, Marinda, told Tarleton on Wednesday that she looked beautiful, adding she was certain her mother had somehow picked Tarleton. "They are both mothers, they are both survivors, they are both beacons of light," she said.

Righter said that after meeting Tarleton for the first time Tuesday, she felt overjoyed for the first time in a long time.

"I get to feel my mother's skin again, I get to see my mother's freckles, and through you, I get to see my mother live on," she said. "This is truly a blessing."

Tarleton is legally blind and read her remarks from a tablet. She thanked Righter's family for what she called "a tremendous gift" that's greatly alleviated the physical pain she'd felt daily.

Tarleton referred to the victims of the Boston Marathon bombing and said the city is "facing the challenges of pain and forgiveness."

"There is a lot to learn and take from horrific events that happen," Tarleton said. "I want others to know that they need not give up on feeling themselves when tragedy strikes, but instead they can make a choice to find the good and allow that to help them heal."

Graphene's high-speed seesaw

Apr. 29, 2013 ? A new transistor capable of revolutionising technologies for medical imaging and security screening has been developed by graphene researchers from the Universities of Manchester and Nottingham.

Writing in Nature Communications, the researchers report the first graphene-based transistor with bistable characteristics, which means that the device can spontaneously switch between two electronic states. Such devices are in great demand as emitters of electromagnetic waves in the high-frequency range between radar and infra-red, relevant for applications such as security systems and medical imaging.

Bistability is a common phenomenon -- a seesaw-like system has two equivalent states and small perturbations can trigger spontaneous switching between them. The way in which charge-carrying electrons in graphene transistors move makes this switching incredibly fast -- trillions of switches per second.

Wonder material graphene is the world's thinnest, strongest and most conductive material, and has the potential to revolutionise a huge number of diverse applications; from smartphones and ultrafast broadband to drug delivery and computer chips. It was first isolated at The University of Manchester in 2004.

The device consists of two layers of graphene separated by an insulating layer of boron nitride just a few atomic layers thick. The electron clouds in each graphene layer can be tuned by applying a small voltage. This can induce the electrons into a state where they move spontaneously at high speed between the layers.

Because the insulating layer separating the two graphene sheets is ultra-thin, electrons are able to move through this barrier by 'quantum tunnelling'. This process induces a rapid motion of electrical charge which can lead to the emission of high-frequency electromagnetic waves.

These new transistors exhibit the essential signature of a quantum seesaw, called negative differential conductance, whereby the same electrical current flows at two different applied voltages. The next step for researchers is to learn how to optimise the transistor as a detector and emitter.

One of the researchers, Professor Laurence Eaves, said: "In addition to its potential in medical imaging and security screening, the graphene devices could also be integrated on a chip with conventional, or other graphene-based, electronic components to provide new architectures and functionality.

"For more than 40 years, technology has led to ever-smaller transistors; a tour de force of engineering that has provided us with today's state-of-the-art silicon chips which contain billions of transistors. Scientists are searching for an alternative to silicon-based technology, which is likely to hit the buffers in a few years' time, and graphene may be an answer."

"Graphene research is relatively mature but multi-layered devices made of different atomically-thin materials such as graphene were first reported only a year ago. This architecture can bring many more surprises," adds Dr Liam Britnell, University of Manchester, the first author of the paper.

Samsung launching Galaxy S4 in India ?Gangnam Style?

During their launch event at India for the Galaxy S4, Samsung decided to hire popular Bollywood actor Ranveer Singh to do their own version of Psy's "Gangnam Style". Except in this case it's "Samsung Style".?

The song goes into surprising depth about the new Galaxy S4 and it's many features. Half way through it mixes the English lyrics with Hindi, but still worth a watch with your late morning coffee.

Court rules in favor of NYSE, Nasdaq in NetCoalition case

NEW YORK (Reuters) - A U.S. appeals court on Tuesday dismissed complaints filed by Google , Yahoo! and other Internet companies that sought to reduce the fees the New York Stock Exchange and Nasdaq Stock Market charge for market data, saying the Dodd-Frank bill stripped it of jurisdiction in the case.

The U.S. Court of Appeals for the District of Columbia Circuit ruled against the NetCoalition group of Internet companies, which included Google and Yahoo, and the Securities Industry and Financial Markets Association, a lobby for brokers.

Sifma and the NetCoalition group had challenged changes to the Securities Exchange Act that were included in Dodd-Frank, which allowed NYSE and Nasdaq to file new fee schedules that were "immediately effective" and sidestep regulatory review.

The court had ruled in an earlier case that competition should determine whether market data - prices for stock quotations and share prices - are "fair and reasonable," but the court said Dodd-Frank "ousts us of jurisdiction."

The court said that because the SEC is no longer required to approve an exchange's filing for new fees before it becomes effective, its prior ruling is inoperative.

Lenovo unveils touchscreen ThinkPad S431, ships ThinkPad Edge E431 and E531

Lenovo unveils touchscreen ThinkPad S431, ships ThinkPad Edge E431 and E531

Lenovo is giving fans of professional laptop chic a treat today: in addition to shipping the ThinkPad Edge E431 and E531, it's unveiling one more model, the ThinkPad S431. The new Ivy Bridge-powered system is closer to the Edge S430 in spirit, carrying a similar 0.8 inches thick chassis, an aluminum lid and a thin-bezel design that stuffs a 14-inch touchscreen into a small body. It does carry the newer Edge line's unifying OneLink connector and gesture-friendly touchpad, although the svelter profile also involves some sacrifices -- the S431 tops out at 8GB of RAM and a 500GB hard drive, or about half what its peers can manage. The slimmer, touch-enabled design will also boost the asking price to $699 when the S431 ships in June, although the cost conscious can spring for the E431 and E531 today for a distinctly cheaper $599.
