Feast your eyes on the world's highest, longest bridge, a virtual reality experience that shows the surreal world of Salvador Dali's art and zoom along with drone racers. Above: Glass bridges are becoming all the rage in the China. There's one in Hunan Province, for example, that's 984 feet long and spans a 590-foot deep crevasse. Now Israeli architectural firm Haim Dotan is on track to build a 1410-foot-long one over the Zhangjiajie Grand Canyon, 984 below. The architects say it should hold 800 people at a time. You first.

To show just how aerodynamic their seven-seater X-Trail crossover vehicle is, Nissan built a seven-seater bobsleigh. British Olympic medallist Sean Olsson took it for a spin at the Igls Olympic track in Innsbruck, Austria, and found that the sled accelerated from 0 to 62 mph in 30 seconds. We're wondering if it has cupholders.

Scientists at Harvard University have discovered that a simple fold in origami called mountain-valley fold is so versatile, it could be the key to creating just about any shape. Objects that fold and collapse into smaller packages could have applications in space travel, architecture, surgery and robotics.

The Lifeshirt from Aegis is a shirt you can wear while boating, surfing, waterskiing, etc. But unlike other shirts, this one works like a floatation device in emergency situations. Just pull the handle in the shoulder and a CO2-cylinder inflates a bladder designed to keep the head above water. The shirt can also be set to automatic and inflate as soon as it detects that the wearer is submerged in water.

In an interview this week with CBS’ Gayle King, the Obamas said the White House Wi-Fi needed an upgrade.
“...it is an old building, and so there’s a lot of dead spots where Wi-Fi doesn’t work,” President Obama said. The first lady added that wireless access could be “a little sketchy,” which irritated their daughters.
President Obama wants the issue fixed before the next president arrives, but it may not be as simple as waiting for a technician to show up. That’s because, spottiness aside, this is not just any Wi-Fi.
The issue with Wi-Fi dates back to 2012 — prehistoric in terms of Internet speed.
In March of that year, Nextgov’s Bob Brewin spotted a Defense Information Systems Agency “notice to industry” on the Federal Business Opportunities website requesting a White House campus Wi-Fi network.
It needed to serve 60 buildings, several outdoor areas and accommodate sensitive data. The goal was simply to move from place to place without losing a signal.
“The agency specified the latest Wi-Fi standard, 802.11n, which has a raw data rate of 600 megabits a second and backward compatibility with the older 802.11 a/b/g standards,” Brewin, who passed away in 2014, wrote at the time.
They finally got it.
But a more advanced standard called 802.11ac exists now and it has 1300 megabits per second capacity. There's no indication that the White House network got upgraded.
Regardless of the standard, any technology wielded by the leader of the free world must be secure. White House officials don’t reveal much, but from what we’ve seen everything goes through serious vetting. Remember how Obama fought to keep his BlackBerry? And he’s still not allowed to have an iPhone for security reasons.
So I’m sure the Wi-Fi network was also subjected to an intense process.
The constant challenge is balancing security and functionality. Retired general James E. Cartwright, who was on the Joint Chiefs of Staff during Obama’s first term, recently told the New York Times how DARPA modified his iPad. They took out the cameras, wireless chips, location sensors, microphones, and disconnected it from any network.
“What I ended up with was a pretty dumb iPad,” he said. Sounds like the Obamas ended up with a pretty dumb wireless network, too. Maybe by the end of the next president’s term, the signal will be slightly stronger.
