COPIE O CÓDIGO ABAIXO E COLOQUE ESTA TIRINHA NO SEU SITE OU BLOG

Mehmet Oz, America's doctor, is known for many things, but being a proponent of good science isn't one of them. Last summer, he was even dragged up to Capitol Hill and berated by senators for his bunk weight-loss prescriptions. "The scientific community is almost monolithic against you," Sen. Claire McCaskill admonished him.

Now comes more evidence of Oz's wizardry: according to the blog Retraction Watch, a key study that the TV doctor used to tout a green coffee bean extract for weight loss has been retracted. "The sponsors of the study cannot assure the validity of the data so we, Joe Vinson and Bryan Burnham, are retracting the paper," the journal's retraction notice reads.

Even before the retraction, the study had attracted a lot of scrutiny for being too weak and flawed to support any health claims, let alone weight loss wonders. The Federal Trade Commission had also settled a $3.5-million lawsuit with the supplement-makers for its false marketing and bad science. This from the FTC's September press release about the settlement:

The FTC charges that the study’s lead investigator repeatedly altered the weights and other key measurements of the subjects, changed the length of the trial, and misstated which subjects were taking the placebo or GCA during the trial. When the lead investigator was unable to get the study published, the FTC says that AFS hired researchers Joe Vinson and Bryan Burnham at the University of Scranton to rewrite it.

Despite receiving conflicting data, Vinson, Burnham, and AFS never verified the authenticity of the information used in the study, according to the complaint. Despite the study’s flaws, AFS used it to falsely claim that GCA caused consumers to lose 17.7 pounds, 10.5 percent of body weight, and 16 percent of body fat with or without diet and exercise, in 22 weeks, the complaint alleges.

Although AFS played no part in featuring its study on The Dr. Oz Show, it took advantage of the publicity afterwards by issuing a press release highlighting the show. The release claimed that study subjects lost weight "without diet or exercise," even though subjects in the study were instructed to restrict their diet and increase their exercise, the FTC contends.

More writing.

Here’s some more excellent parenting.

Newly released documents definitively show that local law enforcement in Washington, DC, possessed a cellular surveillance system—commonly known as a "stingray"—since 2003. 

However, these stingrays literally sat unused in a police vault for six years until officers were trained on the devices in early 2009.

"It's life imitating The Wire," Chris Soghoian, a staff technologist at the American Civil Liberties Union, told Ars. "There's an episode in Season 3 where [Detective Jimmy] McNulty finds a [stingray] that has been sitting on the shelf for a while." (more)

Uma das atrações da Audi no Salão do Automóvel de São Paulo será o conceito Urban, que já foi mostrado durante o Salão de Frankfurt de 2011. O modelo conta com versões cupê e conversível, ambos com a mesma proposta de ser um automóvel urbano, tanto é que o conjunto mecânico elétrico conta com autonomia de apenas 70 quilômetros, ideal para rodar nas grandes cidades.

O novo Audi Urban Concept traz como destaque o uso de materiais leves e também algumas soluções visuais, como os para-lamas com feixe de LED. Na versão conversível, o Audi traz portas que se abrem diagonalmente para cima. O cockpit é feito de polímero reforçado com fibra de carbono. O interior do modelo dispõe de apenas dois lugares defasados – o assento do motorista fica mais à frente do passageiro.

São dois motores elétricos que equipam o Urban, com potência de 20 cavalos e 4,8 kgfm de torque, alimentados por baterias de íon de lítio de 7,1 kWh. O peso do modelo é de apenas 480 quilos.

iFixIt has conducted its teardown of the brand new Mac mini, finding that the new device is more difficult to open than previous models. They've also discovered that the RAM is soldered onto the machine, which was first discovered late last week.


The team found that gaining entry into the new desktop is more difficult than previous models. Instead of a twistable bottom cover, the new Mac mini requires a plastic opening tool to pop off the cover. Underneath that is a new solid door that blocks easy access to the RAM and fan. The door uses what iFixIt calls "the smallest Torx Security screw" they've ever seen, requiring their tool design team to prototype a new screwdriver to open the desktop.

Inside, the Mac mini now sports a new AirPort card that connects straight to a PCIe slot rather than via a cable. Unlike past Mac minis, the new version only contains one SATA port. Previously, Mac mini users could upgrade their desktops with an extra hard drive. However, iFixIt notes that there is an extra socket that could potentially be used for a SSD blade via a PCIe cable. Oddly, the new Mac mini's power supply is identical to both the 2012 and 2011 models.

Finally, iFixIt gave the new Mac mini a repairability score of 6 out of 10, which is a worse score than the 2012 Mac mini's 8 out of 10. Although disassembly is straight forward, the team noted that the presence of Torx security screws and soldered on RAM made it more difficult to repair than previous models.

Don’t make any sudden movements. It’s probably just as frightened as you are.
