Is Pinterest more popular than Tumblr in the U.S.?
New data compiled by Royal Pingdom seems to indicate that Pinterest has overtaken Tumblr in terms of traffic.
The ‘Pinners’ are laughing at us, comrades.
CNET is tumbling all the best product reviews, news, photos, videos, and tech goodness from across the Web.

When the aliens call, who’ll answer?
A new poll suggests that 77 percent of Americans think there’s evidence that aliens have already visited Earth. The same poll suggests most Americans think President Barack Obama would do a better job than presumptive GOP challenger Mitt Romney if we had to fight off an alien invasion. And if we have to rely on a superhero to save us, they’d rather go with the Hulk than Batman.
That somewhat silly survey was conducted to tout a “Chasing UFOs” TV series on the National Geographic Channel, but the results raise a serious question: If an alien civilization does get in touch with us, who’s in charge of figuring out what to do?
This kid looks like he can handle it:

Fun fact: Google’s I/O keynote is taking place in the same room that Apple’s WWDC keynote was in 2 weeks ago.

Seth MacFarlane donates Carl Sagan’s papers to Library of Congress
Not only is he rebooting Sagan’s iconic Cosmos TV series for Fox next year (starring Neil deGrasse Tyson, no less), now he has generously donated money to allow the U.S. Library of Congress to acquire Carl Sagan’s personal papers.
Included in the papers are personal letters, drafts of the Contact screenplay, academic articles, and the childhood drawing that you see above.
It’s appropriate that the great communicator of science, who believed that it should be accessible to everyone, should have his personal papers given the same privilege.

American and Israeli researchers have used twisted vortex beams to transmit data at 2.5 terabits per second. As far as we can discern, this is the fastest wireless network ever created — by some margin. This technique is likely to be used in the next few years to vastly increase the throughput of both wireless and fiber-optic networks.
These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM.
In this case, Alan Willner and fellow researchers from the University of Southern California, NASA’s Jet Propulsion Laboratory, and Tel Aviv University, twisted together eight ~300Gbps visible light data streams using OAM. Each of the eight beams has a different level of OAM twist. The beams are bundled into two groups of four, which are passed through different polarization filters. One bundle of four is transmitted as a thin stream, like a screw thread, while the other four are transmitted around the outside, like a sheathe. The beam is then transmitted over open space (just one meter in this case), and untwisted and processed by the receiving end. 2.5 terabits per second is equivalent to 320 gigabytes per second, or around seven full Blu-ray movies per second.
This huge achievement comes just a few months after Bo Thide finally proved that OAM is actually possible.

The iPhone at 5: From uncertainty to runaway hit
Apple’s iPhone first went on sale five years ago tomorrow. CNET gazes back at some of its early flaws, and looks to what lies ahead.

Apple’s iPhone 4 is still at the top of the list for Flickr users, according to analysis of the 7.2 billion photos uploaded to the site between April and June.
The phone, which was No. 1 last year as well, has beaten out several actual cameras — the Canon EOS 5D Mark II, Canon EOS Rebel T2I, and Nikon D90 — as well as its brethren, the iPhone 4S, which made the list at No. 3.
