The most adorable thing you’ll see today
The Los Angeles Unified School District has taken a step forward in its $1-billion plan to equip every student with an iPad. The program launched in two elementary schools yesterday, though critics stand firm that the effort is far too expensive, and unnecessary.
As for the students above:

The truth is finally out there on Area 51
After years of wild speculation about the existence and true nature of Area 51, and frequent appearances in all sorts of alien-themed works of pop culture, the CIA has revealed details of the secretive military base. In a 400-page document dump, the agency has officially confirmed the existence of the base, and confirmed that it played host to secretive U-2 stealth plane testing.
“There is a section on the relationship between the U-2 program being responsible for UFO sightings,” National Security Archive senior fellow Jeffrey Richelson told the Los Angeles Times on Friday. “But if people are looking for sections on dead aliens and inter-species contact, they’ll be disappointed. It’s just not there.”
That is, of course, unless you think there are still extraterrestrial secrets locked away somewhere, kept under the close watch of the Smoking Man.

Meet the Hyperloop, the possible future of transportation
Tesla Motors CEO Elon Musk isn’t exactly one to dream small: Just look at his plan for a so-called Hyperloop transportation system, which would reach speeds of more than 700 mph, has just been officially unveiled.
While a network of tube transports that would make a trip from Los Angeles to San Francisco as short as 30 minutes seems ridiculous, remember that Musk is also leading SpaceX, which aims to commercialize space travel.
Said Musk in his unveiling of the Hyperloop:
When the California “high speed” rail was approved, I was quite disappointed, as I know many others were too. How could it be that the home of Silicon Valley and JPL – doing incredible things like indexing all the world’s knowledge and putting rovers on Mars – would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world?
As for how the whole thing works:
Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube. The capsules are supported on a cushion of air, featuring pressurized air and aerodynamic lift.
The capsules are accelerated via a magnetic linear accelerator affixed at various stations on the low pressure tube with rotors contained in each capsule. Passengers may enter and exit Hyperloop at stations located either at the ends of the tube, or branches along the tube length
All of that said, there are no immediate plans to construct the loop, and that the project is currently “extremely speculative.”

Panoramic Tokyo, in extreme detail
The photo above is a sample of the ridiculously-detailed panoramic shot taken by photographer Jeffrey Martin. Coming in at a whopping 150-gigapixels, the full photo would be 330 feet wide if fully printed out.
It took months to assemble and stitch the nearly 16,000 photos from about 128 gigabytes of jpeg files into three sections that were then combined into the 360-degree panorama, which itself was a 200gb psb file.

Times staffer Ralph Vartabedian has a fascinating report about the development, launch and personalities behind Syncom, the first communications satellite, which was built in Los Angeles and sent into orbit in 1963.
Of all the technological breakthroughs made in Los Angeles during the Cold War — the laser, the first supersonic jet fighter, the Apollo moon ship, stealth aircraft, the space shuttle, the intercontinental ballistic missile system and much else — the creation of a communications satellite has had the largest and most enduring cultural, social and economic impact.
After the satellite entered orbit, President John F. Kennedy had a somewhat-awkward conversation with Nigerian Prime Minister Abubakar Tafawa Balewa.
Several weeks after the Syncom launch, President Kennedy inaugurated international satellite telephone service to Nigeria, where the Navy had stationed its receivers. The symbolic phone call to Nigerian Prime Minister Abubakar Tafawa Balewa lasted two minutes.
Kennedy and Balewa traded pleasantries, briefly mentioned the nuclear weapons test ban treaty signed that year, and talked about a boxing match in which Nigerian middleweight boxer Dick Tiger had retained his title against an American.

July 29, 1958: NASA is Created
On this day in 1958, the United States Congress passed legislation creating the National Aeronautics and Space Administration (NASA). Since its creation, NASA has played a vital role in coordinating all of the US’ activity in space. The agency spearheads and sponsors space exhibitions and has launched numerous orbiting satellites that have produced information about the solar system and universe.
In recent years, many feel that NASA has experienced numerous setbacks. The most significant being the end of the space shuttle program in 2011.
Celebrate NASA’s birthday with PBS NewsHour’s video of the agency’s newest vehicle “Curiosity.”

Celebrating Syncom: The pioneering communications satellite
Its name may not be as familiar as Sputnik’s, but that doesn’t mean the Syncom communications satellite deserve no celebrations on its 50th anniversary.
In fact, it was Sputnik that inspired one of Syncom’s creators, Harold Rosen, in the first place. Rosen, then a student at Caltech, watched the Soviet satellite streaking across the sky as he brainstormed:
What he imagined by 1959 was a revolution in communications: an extremely lightweight, solar-powered telephone switching station in orbit 22,000 miles above Earth. In those days, an international telephone connection required making a reservation because the existing system — copper cables and radio signals — carried few calls. Many countries could not be called at all. A satellite could change all of that.
Just think - without the successful launch of Syncom on July 26, 1963, the quick rise of international television signals, electronic credit card authorizations and countless other innovations would be completely different.
And what once was a single 78-pound satellite has turned into more than 500 descendants currently orbiting the Earth, some of which weigh more than 13,000 pounds.

See that little dot in the distance? That’s Earth.
NASA’s Cassini spacecraft took some incredible photos of our home planet Friday, which the agency finally released yesterday.
The craft is current orbiting Saturn, as seen above, and is often unable to sneak a peek at Earth due to its relative closeness to the sun. So how did we get a hold of these stunning photos?
…on Friday, Saturn moved between Cassini and the sun, casting the spacecraft in shadow and allowing it to look back toward the inner solar system without the risk of ruining the detectors on its cameras.
Thanks to this orbital geometry, Saturn’s rings were also backlit by the sun, giving Cassini the rare opportunity to snap images of the powdery dust in Saturn’s rings in hyper-sharp detail.

Tumblr users have always had the option of marking their account as NSFW, and since around 10% of Tumblr is porn, people were generally pretty good at labelling their blogs.
However, under Tumblr’s new content restrictions, posts from Adult-rated blogs will no longer show up on tags. Any tags. Also, Tumblr is able to flag your account as Adult without you labelling it as such—although users do have the option of appealing to the “Trust & Safety Team” if their feel their blog has been flagged unfairly.
Adult blogs are now unsearchable.
If your blog has been flagged as Adult, nothing you post will ever appear on Tumblr’s public tag searches. Your posts will only be visible to your own followers and the followers of people who reblog your content.
This means that if you want to publicize something like a Kickstarter campaign or political message, or even to signal boost a personal plea for help, that post will still not show up on Tumblr’s internal search engine. You are cut off from everyone except your own circle of followers.
Also, Many Tumblr users are finding that some tags have disappeared entirely from Tumblr’s iPhone app.
It’s unclear whether this is directly linked to the new content restrictions, but for example, iPhone users searching the #gay, #lesbian or #bisexual tags have reported seeing the result “No posts found,” although #bi, #lgbt and #queer still produce results. [READ MORE]
Continuing to reblog this story because this is 100% bad news bears.
This is an awkward situation all around. How do you think Tumblr could have handled this situation better, folks? I bet they’d love constructive feedback here. Shoot us an ask. Will share the best ideas with everyone.
Head on over to ShortFormBlog for a interesting discussion on how Tumblr should manage its complicated NSFW issue.

Settling the debate over the nature of the T. rex
One question has hounded the T. rex, perhaps the most famous dinosaur of them all, for years. Were they terrifying, active predators? Overgrown vultures? Or perhaps a mix of the two?
Now for the first time, there’s direct evidence that T. rexes were hunters, with palentologists discovering a vertebrae of a hadrosaur that had healed around a T. rex tooth, suggesting the prey had been alive when it was bitten.
The tooth crown and vertebrae found in South Dakota’s Hell Creek Formation is “the piece that settles the controversy,” said University of Kansas paleontologist David Burnham, a member of the study team.
