UK lawmakers: Rupert Murdoch unfit to lead company

(AP) ? News Corp. chief Rupert Murdoch is unfit to lead his global media empire, an influential group of British lawmakers said Tuesday.

In a scathing report, the lawmakers said his company misled Parliament about the scale of phone hacking at one of its tabloids.

Parliament's cross-party Culture, Media and Sport committee said News International, the British newspaper division of Murdoch's News Corp., had deliberately ignored evidence of malpractice, covered up evidence and frustrated efforts to expose wrongdoing.

Murdoch has insisted he was unaware that hacking was widespread at his now-shuttered News of the World tabloid, blaming underlings for keeping him in the dark.

The legislators said if that was true, "he turned a blind eye and exhibited willful blindness to what was going on in his companies."

"We conclude, therefore, that Rupert Murdoch is not a fit person to exercise the stewardship of a major international company," the report by the panel of 11 lawmakers said.

Labour Party panel member Tom Watson said the decision had not been unanimous, and Conservative lawmakers Louise Mensch ? who opposed condemning Murdoch ? said the split had been along party lines.

The judgment on Murdoch implies that News Corp., which he heads, is also not a fit to control British Sky Broadcasting, in which News Corp. holds a controlling stake of 39 percent.

The committee agreed unanimously that three key News International executives misled Parliament by offering false accounts of their knowledge of the extent of phone hacking at the News of The World ? a rare and serious censure which usually demands a personal apology to legislators.

Murdoch closed down the 168-year-old Sunday tabloid last July amid public revulsion at the hacking of voice mail messages of celebrities and victims of crime, including murdered schoolgirl Milly Dowler.

Throughout the scandal, News International's approach "was to cover up rather than seek out wrongdoing," the legislators wrote.

Researchers make an RGB laser with a regular laser and quantum dots

Researchers make an RGB laser with a regular laser and quantum dots

The problem with lasers is, they tend to generate just a single color or light.To get more than one hue requires actually combining more than one type of laser to produce red, green and blue. But researchers at Brown University have figured out a solution to creating small RGB lasers by using colloidal quantum dots, or CQDs. The idea of leveraging the properties of the thin film isn't new, but past attempts to use CQDs in semiconductor lasers have failed because the necessary energy tends to wind up as heat instead of light. The work around scientists found was to excite the various dot sizes with a laser then filter out original light source. Unfortuneately, the solution is far from practical for use in commercial products, but it does represent a milestone in the march towards a single-material multi-wavelength laser.

Short sleep duration increases expression of genetic risks for high body mass index

DARIEN, IL Toss out another old wives' tale: Sleeping too much does not make you fat. Quite the opposite, according to a new study examining sleep and body mass index (BMI) in twins, which found that sleeping more than nine hours a night may actually suppress genetic influences on body weight.

The study looked at 1,088 pairs of twins and found that sleeping less than seven hours a night was associated with both increased BMI and greater genetic influences on BMI. Previous research has shown that genetic influences include things like glucose metabolism, energy use, fatty acid storage and satiety. In this study, the heritability of BMI was twice as high for the short sleepers than for twins who slept longer than nine hours a night.

"The results suggest that shorter sleep provides a more permissive environment for the expression of obesity related genes," said principal investigator Nathaniel Watson, MD, MSc, of the University of Washington. "Or it may be that extended sleep is protective by suppressing expression of obesity genes."

Watson and colleagues determined that for twins sleeping less than seven hours, genetic influences accounted for 70 percent of the differences in BMI, with common environment accounting for just 4 percent and unique environment 26 percent. For twins averaging more than nine hours of sleep, genetic factors were attributed to 32 percent of weight variations, with common environment accounting for 51 percent and unique environment 17 percent.

More research is needed, Watson said, but these preliminary results may suggest that behavioral weight loss measures would be most effective when genetic drivers of body weight are mitigated through sleep extension.
