Congress to examine government's dominance in wireless spectrum

Image

The US federal government is, by far and away, the largest user of wireless spectrum in the States -- much of which is spoken for by the Department of Defense. A new Congressional committee will, however, be re-examining that position with the goal of freeing up airwaves for public and commercial use. Brett Guthrie (R-KY), who will co-chair the group, hopes the effort will ultimately end up saving taxpayers money and satiating the country's "exploding demand for mobile broadband services." Of course this isn't the first time the idea has been broached, but the bi-partisan collective suggests that an actionable plan to ease the spectrum squeeze might not be too far off. Let's all hope that the findings don't become quite as contentious as some of the other issues currently being debated in Congress's hallowed halls.

Jack Dorsey Talks Square, Twitter, And Instagram-Facebook With Charlie Rose

Charlie Rose - Jack DorseyTwitter co-founder, and Square CEO and co-founder Jack Dorsey sat down with Charlie Rose yesterday (you can watch the full video clip here) to talk about the two companies he's developed as well as Facebook's $1 billion acquisition of Instagram and the "digital revolution." The entire interview is just under 18 minutes, and is worth a watch, but here are some of the highlights: As Square revealed yesterday, the payments company is now processing $5 billion in annual payments (or around $416 million in payments per month), which is up from $4 billion in annual payments in March. Dorsey says that Square is moving fast, and this year will be expanding internationally, both to local shops and larger merchants. "We want to be the point of sale for every merchant," he tells Rose.

Intel Core i7-3770K CPU review roundup: crossing the Ivy Bridge

Ivy Bridge

Today is officially Ivy Bridge day, in case you didn't already know. Intel took the wraps off the latest member of its processor family and the internet wasted no time putting the flagship Core i7-3770K through its paces. The 3.5GHz quad-core desktop chip comes packing not only some architectural tweaks, but a brand new integrated GPU in the form of the HD 4000. Oh, and it does all this using a brand new 22nm manufacturing process and 3D "Tri-Gate" transistors. What does that mean for you, the user? Lower power consumption, better performance and, surprisingly, unbelievably fast media transcoding. When AnandTech turned its eyes towards Quick Sync, the on-die media transcode engine introduced with Sandy Bridge, the 3770K practically buried the competition. Using Cyberlink Media Espresso the new chip turned a DRM-stripped Blu-ray of Harry Potter (130 minutes of 1080p video) into an iPad friendly format in just seven minutes without taxing the CPU.

At idle, power consumption hasn't changed much, but when TechSpot put the pedal to the metal things looked quite a bit different. The new i7-3770K sucked down just 147 watts, which was even four watts less than lower clocked i5-2500K. And, of course, it delivered much better performance. In fact, in Bit-Tech's tests, the only chip that was able to routinely best it was the hexa-core 3960X Extreme Edition -- and even that CPU barely eked out its victories. While AMD's offerings simply can't compete with Intel's on pure performance or power consumption, it does still outrun run Chipzilla's GPU. The HD 4000 is, undeniably, a huge step forward for the Core line, but it falls just short of matching the A8's integrated Radeon on Tech Report's tests.

Nokia flips internet sharing switch on for Lumia 710 and 800c in Tango update

Nokia flips internet sharing switch on for Lumia 710 and 800c in Tango update

Looks like Espoo's finally ready to do the Tango with Lumia owners. According to a report on Nokiapoweruser, updates for localized variants of the 710 and the China-only 800c have been spotted on NaviFirm, indicating a planned firmware rollout for those WP 7.5 devices is underway. Users in Belgium, the Netherlands and Vietnam who download the software should see that previously dormant internet sharing ability enabled, in addition to the installation of a trio of Nokia apps -- Sportstracker, News and Creative Studio -- as standard on handsets. No word on when the company intends to release the package to other markets, but with this latest news, it can't be far off now.

[Thanks, Nish]

Demo 2012: Looking for the Next Google, Facebook or Apple

Demo is a fascinating show. What you see is a string of companies that each have six minutes to pitch their products to an audience of media, investors, other companies (who might buy them), and peers. My initial thought is that my friend Carmine Gallo, who wrote The Presentation Secrets of Steve Jobs and teaches people how to present, could make a living helping these folks present properly.

What did the scientist say to the sommelier? 'Show me the proof'

ScienceDaily (Apr. 22, 2012) ? What does lemon pan sauce chicken have to do with biochemistry and molecular biology? If you ask the students in Joseph Provost's class at Minnesota State University Moorhead, they'll tell you that successful execution of the dish requires the Maillard reaction, a chemical process that's responsible for the flavors and colors in a variety of food, including toast and maple syrup.

In Provost's class, students are asked to do what would be unthinkable in a traditional science course: eat the results of their experiments.

"There are a few universities that teach this class, but I wanted to use the theme to bring science to a wider audience," Provost explains. "There is a ton of interesting biochemistry, chemistry, biology and physics involved with cooking, and all of it can be brought to this topic." Each section of his course is about food -- and explained with all of the interesting science involved. Provost says, "That is different than many courses, where the application is at the end of the chapter."

On April 22, Provost shared with other educator-scientists his recipe for making science accessible to liberal arts students with the hope that they, too, will cook up innovative teaching techniques. His presentation will be part of the American Society for Biochemistry and Molecular Biology annual meeting, held in conjunction with the Experimental Biology conference in San Diego.

Begun in the fall of 2010, Provost's Science of Cooking class draws about 150 students each semester and requires 12 hours of lab experience, which can be acquired in either the lecture hall or in students' homes. Together with a team of faculty, he hopes to create a textbook that can be used for non-science majors throughout the United States.

One (in-class) experiment covers freezing point depression through ice-cream making. "Students work in groups using various salt solutions to measure freezing point depressions, create secondary plots to determine trends and analyze the impact of salt and sucrose on making ice cream," Provost says. Later the students use a scientific approach to how biological molecules impact the taste of ice cream. He also uses convection, microwave and induction cooking teach the physics behind heat transfer.

Dishes such as cheese souffl? are used to examine protein denaturation and gas laws. Meanwhile, marinating shrimp is used as a launching point for discussions of acid denaturation of meats and how free amino acids affect taste.

"There are a lot of ways to get people interested in science. I think this a great way to show how biochemistry can daily impact their life," Provost says. "It also makes them a much better cook!"

20M Users Strong, Lookout Partners With Deutsche Telekom To Bring Mobile Security Apps To Europe

deutsche-telekomLookout, a company that offers security services for a number of smartphone platforms, is continuing its international expansion to Europe with a strategic partnership with European telecommunications giant. Deutsche Telekom. Financial terms of the partnership were not disclosed. For background, Lookout?s web-based, cloud-connected applications for Android, Windows Mobile, BlackBerry and iOS devices help users from losing their phones and identifies and block threats on a consumer?s phone. Users simply download the software to a device, and it will act as a tracking application, data backup and a virus protector much like security software downloaded to a computer. People can also manage multiple mobile devices and locate a phone or tablet on a Google map. Lookout, which now has 20 million users, says it identified more than 1,000 instances of mobile malware in 2011, which is a significant increase since 2010.
