When the Delaware Supreme Court revived a family’s lawsuit late last month over a school resource officer’s intense interrogation of their third-grade son, it reignited the debate about having police officers stationed at schools to investigate matters that used to be handled by school administrators.

According to court papers, the questioning was so intense, complete with threats of the children being sent to a juvenile facility for lying, that the 8-year-old — who was not a suspect — burst into tears.

These demands for master encryption keys, which have not been disclosed previously, represent a technological escalation in the clandestine methods that the FBI and the National Security Agency employ when conducting electronic surveillance against Internet users.

"The government is definitely demanding SSL keys from providers," said one person who has responded to government attempts to obtain encryption keys. The source spoke with CNET on condition of anonymity.

"The requests are coming because the Internet is very rapidly changing to an encrypted model," a former Justice Department official said. "SSL has really impacted the capability of U.S. law enforcement. They're now going to the ultimate application layer provider."

Edward Snowden isn't yet allowed to step outside the Moscow airport where he's been holed up for weeks, despite reports to the contrary, his Russian lawyer, Anatoly Kucherena, said Wednesday.

White House spokesman Jay Carney said Wednesday the U.S. government is seeking "clarity" about Snowden's status. And a spokeswoman for Secretary of State John Kerry said Washington would find it "disappointing" if Snowden were allowed to leave the airport.

The agency turns its giant machine brains to the task of sifting through unimaginably large troves of data its surveillance programs capture.

But ask the NSA as part of a freedom of information request to do a seemingly simple search of its own employees' e-mail? The agency says it doesn't have the technology.

"It's just baffling," says Mark Caramanica of the Reporters Committee for Freedom of the Press. "This is an agency that's charged with monitoring millions of communications globally, and they can't even track their own internal communications in response to a FOIA request."

Most households in the UK will have pornography blocked by their internet provider unless they choose to receive it, David Cameron has announced.

He said: "I want to talk about the internet, the impact it is having on the innocence of our children, how online pornography is corroding childhood.

Ms Perry argued filters would make a difference, saying that the killers of schoolgirls April Jones and Tia Sharp had accessed legal pornography before moving on to images of child abuse.

On October 10, 2011, researchers from the University of Minnesota found that women who took supplemental multivitamins died at rates higher than those who didn't. Two days later, researchers from the Cleveland Clinic found that men who took vitamin E had an increased risk of prostate cancer. "It's been a tough week for vitamins," said Carrie Gann of ABC News.

Seven previous studies had already shown that vitamins increased the risk of cancer and heart disease and shortened lives.

In May 1980, during an interview at Oregon State University, Linus Pauling was asked, "Does vitamin C have any side effects on long-term use of, let's say, gram quantities?" Pauling's answer was quick and decisive. "No," he replied.

Seven months later, his wife was dead of stomach cancer. In 1994, Linus Pauling died of prostate cancer.

Bankruptcy would allow Detroit's state-appointed emergency manager, Kevyn Orr, to liquidate the city's assets to try to meet the demands of creditors and pensioners.

But two pension funds representing retired city workers have resisted the bankruptcy plan, and - with tens of thousands of creditors - the city is already facing a number of lawsuits.

Chinese telecom provider Huawei represents an unambiguous national security threat to the United States and Australia, Gen. Michael Hayden, the former director of the National Security Agency (NSA) and the Central Intelligence Agency (CIA) and now a security consultant and director of Motorola Solutions, told the Australian Financial Review, according to a July 19 report.

Hayden said that despite Huawei's best efforts to ease his concerns, "God did not make enough briefing slides on Huawei to convince me that having them involved in our critical communications infrastructure was going to be okay."

Since 1944, physicists at Trinity College in Dublin have been trying to measure the viscosity of pitch tar, a polymer seemingly solid at room temperature, and witness it dripping from a funnel.

"The viscosity of pitch-tar is calculated to be 230 billion times that of water or 230,000 times the viscosity of honey," the college's School of Physics says on the experiment page.

A Pakistani Taliban leader has sent a letter to schoolgirl Malala Yousafzai, 16, expressing shock that she was shot by Taliban gunmen last year.

The Taliban leader also says that his group is not "against education of any men or women or girls". Instead he claims Malala was targeted because she campaigned to "malign [the Taliban's] efforts to establish the Islamic system".
