Intel Haswell's idle states reportedly won't play well with some power supplies

Intel Haswell's lowpower state reportedly won't play well with cheap power supplies

One of the staples of Intel's upcoming Haswell processor architecture is its support for lower-power idle states that can rival tablet chips in power consumption, even on the desktop. However, that may come with a big caveat for budget and custom-built PCs: certain power supplies might not cut it. VR-Zone claims that those idle states require as little as 0.05 amps of current, which could be too nuanced for older or cut-rate supplies that deliver power in bigger clumps. That might not be a problem for companies building complete PCs, but Corsair's Robert Pearce tells The Tech Report that it may lead to a lot of motherboard builders playing it safe by disabling those specific modes by default. Many of us, in turn, would either have to buy a fresh supply or toggle the power-saving options ourselves. We've reached out to Intel to verify the truth, but it may be wisest to make a cleaner break from the past with any near-term upgrades.

Official: Arrested student entered US without visa

WASHINGTON (AP) ? One of three college students arrested Wednesday in the Boston Marathon bombings case was allowed to return to the United States from Kazakhstan in January despite not having a valid student visa, a federal law enforcement official told The Associated Press.

Authorities charged the student ? a friend and classmate of one of the men accused of setting off the deadly explosions ? with helping after the attacks to remove a laptop and backpack from the bombing suspect's dormitory room before the FBI searched it.

The government acknowledged that U.S. Customs and Border Protection was unaware that the student was no longer in school when he was let back into the United States.

The disclosure was another instance of possible lapses by the federal government in the months before the Boston bombings. The Obama administration earlier this week announced an internal review of how U.S. intelligence agencies shared sensitive information and whether the government could have disrupted the attack. Republicans in Congress have promised oversight hearings starting next week.

Federal authorities on Wednesday arrested three college friends of Dzhokhar Tsarnaev, a bombing suspect, including Azamat Tazhayakov, a friend and classmate of Tsarnaev's at the University of Massachusetts Dartmouth. Tazhayakov left the U.S. in December and returned Jan. 20. But in early January, his student-visa status was terminated because he was academically dismissed from the university, the official told the AP.

The law enforcement official said information about Tazhayakov's status was in the Homeland Security Department's Student and Exchange Visitor Information System, called SEVIS, when Tazhayakov arrived in New York in January.

The official spoke on the condition of anonymity because this person was not authorized to discuss details of Tazhayakov's immigration history.

DHS spokesman Peter Boogaard said when Tazhayakov arrived on Jan. 20, Customs and Border Protection officials had not been notified that he was no longer a student.

"DHS has recently reformed the student visa system to ensure that CBP is provided with real time updates on all relevant student visa information," Boogaard said. "At the time of re-entry there was no derogatory information that suggested this individual posed a national security or public safety threat."

Tazhayakov and another student from Kazakhstan, Dias Kadyrbayev, were detained last month on immigration charges. They were arrested on federal criminal charges of conspiracy to obstruct justice. Robel Phillipos, 19, was also arrested and charged with willfully making materially false statements to federal law enforcement officials during a terrorism investigation.

Questions about Tazhayakov's immigration status came up Wednesday during an immigration hearing in Boston when a judge questioned how he was able to return to the U.S. in January. A lawyer for Tazhayakov said he had re-enrolled in the university with a different major after returning to the country.

International students who aren't enrolled or are dismissed from a college or university generally have 30 days to rectify their status and re-enroll as long as they are already in the United States.

Lawmakers have questioned information sharing among U.S. law enforcement before the bombings. In 2011, Russian officials notified the FBI and CIA that they were concerned about now-deceased bombing suspect Tamerlan Tsarnaev. In early 2012 Homeland security was alerted of Tamerlan Tsarnaev's travel to and from Russia ? information that was shared with Boston's joint terrorism task force. But the FBI investigation into him had closed and therefore he didn't warrant additional scrutiny, officials have said.

FDA: Morning-after pill OK for ages 15 and up

WASHINGTON (AP) ? The government on Tuesday lowered to 15 the age at which girls can buy the morning-after pill without a prescription and said the emergency contraception no longer has to be kept behind pharmacy counters.

The decision by the Food and Drug Administration is an attempt to find middle ground just days before a court-imposed deadline to lift all age restrictions on the drug.

Today, Plan B One-Step is sold behind pharmacy counters, and buyers must prove they're 17 or older to buy it without a prescription. Tuesday's decision lowers the age limit to 15 ? and will allow the pill to sit on drugstore shelves next to condoms and spermicides or other women's health products. But customers must prove their age at the cash register.

Teva Women's Health, which makes Plan B, said it would begin over-the-counter sales in a few months.

The question is whether Tuesday's action settles a larger court fight. Earlier this month, U.S. District Judge Edward Korman of New York blasted the Obama administration for imposing the age-17 limit, saying it had let election-year politics trump science and was making it hard for women of any age to obtain the emergency contraception in time. He ordered an end to all age restrictions by Monday, for Plan B and its generic versions.

The FDA said Tuesday's decision was independent of the court case and wasn't intended to address it. Technically, the FDA approved Teva's application to sell Plan B in this manner.

The Justice Department remained mum on whether it planned to appeal Korman's decision, and the White House had no immediate comment.

The women's group that sued over the age limits said Tuesday's action is not enough, and it will continue the court fight if necessary.

Lowering the age limit "may reduce delays for some young women but it does nothing to address the significant barriers that far too many women of all ages will still find if they arrive at the drugstore without identification," said Nancy Northup, president of the Center for Reproductive Rights.

The FDA said the Plan B One-Step will be packaged with a product code that prompts the cashier to verify a customer's age. Anyone who can't provide such proof as a driver's license, birth certificate or passport wouldn't be allowed to complete the purchase. In most states, driver's licenses, the most common form of identification, are issued at age 16.

"These are daunting and sometimes insurmountable hoops women are forced to jump through in time-sensitive circumstances, and we will continue our battle in court to remove these arbitrary restrictions on emergency contraception for all women," Northup said.

Other contraceptive contraception advocates called the move promising.

"This decision is a step in the right direction for increased access to a product that is a safe and effective method of preventing unintended pregnancies," said Sen. Patty Murray, D-Wash. "It's also a decision that moves us closer to these critical availability decisions being based on science, not politics."

Social conservatives had opposed any efforts to loosen restrictions on sale of the morning-after pill, arguing that it was important for parents and medical professionals to be involved in such decisions involving young girls.

The group Concerned Women for America charged that health officials were putting politics and so-called progress ahead of the health of children as well as women.

"It makes no sense that kids need parental permission to take aspirin at school, but they're free to buy and administer Plan B," Penny Nance, CEO and president of CWA, said in a statement.

Half the nation's pregnancies every year are unintended, and doctors' groups say more access to morning-after pills could cut those numbers. The pills contain higher doses of regular contraceptives, and if taken within 72 hours of unprotected sex, can cut the chances of pregnancy by up to 89 percent. But it works best if taken in the first 24 hours.

The FDA had been poised to lift all age limits and let Plan B sell over-the-counter in late 2011, when Health and Human Services Secretary Kathleen Sebelius, in an unprecedented move, overruled her own scientists. Sebelius said some girls as young as 11 are physically capable of bearing children but shouldn't be able to buy the pregnancy-preventing pill on their own.

President Barack Obama supported Sebelius' move and a spokesman said earlier this month that the president's position hadn't changed.

The Justice Department could appeal Korman's ruling and seek a stay. If granted, the appeals process would move through the courts, while Plan B is sold over the counter whenever Teva has the product repackaged to meet FDA's requirements.

Absent a stay, "we will want to go back to court as quickly as possible and ask the judge to hold them in contempt," said Janet Crepps, a senior counsel for the Center for Reproductive Rights.

The FDA said Tuesday that Teva had provided data proving that girls as young as 15 could understand how Plan B works and use it properly, without the involvement of a health care provider. Teva plans to conduct a consumer-education program, and indicated it is willing to audit whether stores are following the age requirement, the agency said.

FDA said its ruling applies only to Plan B One-Step, and not to generic versions of the pill which would remain behind pharmacy counters with the age-17 restriction.

If a woman already is pregnant, the morning-after pill has no effect. It prevents ovulation or fertilization of an egg. According to the medical definition, pregnancy doesn't begin until a fertilized egg implants itself into the wall of the uterus. Still, some critics say Plan B is the equivalent of an abortion pill because it may also be able to prevent a fertilized egg from attaching to the uterus, a contention that many scientists ? and Korman, in his ruling ? said has been discredited.

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

Lenovo ThinkPad Edge E431

Lenovo is giving fans of professional laptop chic a treat today: in addition to shipping the ThinkPad Edge E431 and E531 (pictured above), 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.

Toddler is youngest to ever get lab-made windpipe

CHICAGO (AP) ? A 2-year-old girl born without a windpipe now has a new one grown from her own stem cells, the youngest patient in the world to benefit from the experimental treatment.

Hannah Warren has been unable to breathe, eat, drink or swallow on her own since she was born in South Korea in 2010. Until the operation at a central Illinois hospital, she had spent her entire life in a hospital in Seoul. Doctors there told her parents there was no hope and they expected her to die.

The stem cells came from Hannah's bone marrow, extracted with a special needle inserted into her hip bone. They were seeded in a lab onto a plastic scaffold, where it took less than a week for them to multiply and create a new windpipe.

About the size of a 3-inch tube of penne pasta, it was implanted April 9 in a nine-hour procedure.

Early signs indicate the windpipe is working, Hannah's doctors announced Tuesday, although she is still on a ventilator. They believe she will eventually be able to live at home and lead a normal life.

"We feel like she's reborn," said Hannah's father, Darryl Warren.

"They hope that she can do everything that a normal child can do but it's going to take time. This is a brand new road that all of us are on," he said in a telephone interview. "This is her only chance but she's got a fantastic one and an unbelievable one."

Warren choked up and his wife, Lee Young-mi, was teary-eyed at a hospital news conference Tuesday. Hannah did not attend because she is still recovering from the surgery. She developed an infection after the operation but now is acting like a healthy 2-year-old, her doctors said.

Warren said he hopes the family can bring Hannah home for the first time in a month or so. Hannah turns 3 in August.

"It's going to be amazing for us to finally be together as a family of four," he said. The couple has an older daughter.

Only about one in 50,000 children worldwide are born with the windpipe defect. The stem-cell technique has been used to make other body parts besides windpipes and holds promise for treating other birth defects and childhood diseases, her doctors said.

The operation brought together an Italian surgeon based in Sweden who pioneered the technique, a pediatric surgeon at Children's Hospital of Illinois in Peoria who met Hannah's family while on a business trip to South Korea, and Hannah ? born to a Newfoundland man and Korean woman who married after he moved to that country to teach English.

Hannah's parents had read about Dr. Paolo Macchiarini's success using stem-cell based tracheas but couldn't afford to pay for the operation at his center, the Karolinska Institute in Stockholm. So Dr. Mark Holterman helped the family arrange to have the procedure at his Peoria hospital, bringing in Macchiarini to lead the operation. Children's Hospital waived the cost, likely hundreds of thousands of dollars, Holterman said.

Part of OSF Saint Francis Medical Center, the Roman Catholic hospital considers the operation part of their mission to provide charity care, but also views it as a way to champion a type of stem-cell therapy that doesn't involve human embryos, the surgeons said. The Catholic church opposes using stem cells derived from human embryos in research or treatment.

Macchiarini has been involved in 14 previous windpipe operations using patients' own stem cells ? five using man-made scaffolds like Hannah's but in adults; and nine using scaffolds made from cadaver windpipes, including one in a 10-year-old British boy.

He said only one patient died, a 30-year-old man from Abingdon, Md., who had the operation in November 2011 to treat late-stage cancer of the windpipe. He died about four months later of uncertain causes, Macchiarini said.

Similar methods have been used to grow bladders, urethras and last year a girl in Sweden got a lab-made vein using her own stem cells and a cadaver vein.

Scientists hope to eventually use the method to create solid organs, including kidneys and livers, said Dr. Anthony Atala, director of Wake Forest University's Institute for Regenerative Medicine. He said the operation on Hannah Warren "is really showing that the technique is workable."

Hannah had breathing difficulties at birth and Korean doctors soon discovered the missing windpipe. They reconfigured her esophagus so that a breathing tube could go down it from her mouth to her lungs. The esophagus normally runs behind the windpipe and carries food to the stomach.

Korean doctors said she couldn't live long with the tube and told her parents there was nothing more they could do.

Hannah outlived their expectations and has thrived despite the grim prognosis and other abnormalities including an undeveloped voice box that prevented her from speaking. Now that she has a windpipe and can breathe more normally, doctors expect the larynx to grow and function normally. She will work with speech therapists to help her learn to talk.

Holterman said Hannah will likely need a new windpipe in about five years, as she grows.

She breathes with help from a ventilator but no longer has a tube in her mouth that she'd lived with since shortly after birth, Holterman said. She's not yet able to eat normally, but doctors let her have her first taste ever of food ? a few licks on a lollipop. Her father said she already has discriminating taste and prefers chocolate Korean lollipops to the American kind.

"I asked her, 'Is it good?'" he said, "and she immediately nodded her head."
