This Sneaky Camera Can Detect Objects Hidden Around Corners

In the future, staying out of photos may not be as easy as ducking behind a corner. Nature Photonics recently reported on a new camera from scientists at Heriot-Watt University that can detect objects outside of its frame of view using a mechanism similar to the echo location used by bats.

In the video below, the researchers test the device by placing Terry, a 30-centimeter foam figurine, around a corner with the camera situated on the opposite side. They then shine a laser pointer to send short pulses of light to a spot on the floor just outside the camera’s range. Because the ultra-fast, ultra-sensitive camera is sensitive enough to detect single photons, it is able to pick up the light’s “echo” as it rebounds off the object—in this case, Terry—beyond the wall. 

At this stage, the camera is only able to sense small objects no more than a meter away. And while it can pinpoint the exact location of objects even when they’re on the go, it’s still unable to determine shapes. The next step for the team is to develop the technology needed to sense human-sized figures from meters away. In addition to making the world’s sneakiest security camera, it could also be used by cars to detect any incoming vehicles or pedestrians that are out of view.

Attention Business Travelers: These Are the Countries With the Fastest Internet

Whether you travel for business or pleasure, high-speed internet seems like a necessity when you’re trying to connect with colleagues or loved ones back home. Of course, the quality of that connection largely depends on what part of the world you’re in—and if you want the best internet on earth, you’ll have to head to Asia.

Singapore might be smaller than New York City, but it has the fastest internet of any country, Travel + Leisure reports. The city-state received the highest rating from the World Broadband Speed League, an annual ranking conducted by UK analyst Cable. For the report, Cable tracked broadband speeds in 200 countries over several 12-month periods to get an average.

Three Scandinavian countries—Sweden, Denmark, and Norway—followed closely behind Singapore. And while the U.S. has the fastest broadband in North America, it comes in 20th place for internet speed globally, falling behind Asian territories like Japan, Taiwan, and Hong Kong, as well as European countries like Estonia, Latvia, Lithuania, and Spain. On the bright side, though, the U.S. is up one place from last year’s ranking.

In the case of Singapore, the country’s small size works to its advantage. As a financial hub in Asia, it depends heavily on its digital infrastructure, and as a result, “there is economic necessity, coupled with the relative ease of delivering high-speed connections across a small area,” Cable notes in its report. Within Singapore, 82 percent of residents have internet access.

Sweden, Denmark, and Norway, on the other hand, have all focused on FTTP (Fiber to the Premises) connections, and this has boosted internet speeds.

Overall, global broadband speeds are rising, and they improved by 23 percent from 2017 to 2018. However, much of this progress is seen in countries that are already developed, while underdeveloped countries still lag far behind.

“Europe, the United States, and thriving economic centers in the Asia-Pacific region (Singapore, Japan, Taiwan, and Hong Kong) are leading the world when it comes to the provision of fast, reliable broadband, which suggests a relationship between available bandwidth and economic health,” Dan Howdle, Cable’s consumer telecoms analyst, said in a statement. “Those countries leading the world should be congratulated, but we should also be conscious of those that are being left further and further behind."

Samsung Is Making a Phone You Can Fold in Half

The iPhone vs. Galaxy war just intensified. Samsung is pulling out all the stops and developing a foldable phone dubbed Galaxy X, which it plans to release next year, according to The Wall Street Journal.

It would seem the rumors surrounding a mythical phone that can fold over like a wallet are true. The phone, which has been given the in-house code name “Winner,” will have a 7-inch screen and be a little smaller than a tablet but thicker than most other smartphones.

Details are scant and subject to change at this point, but the phone is expected to have a smaller screen on the front that will remain visible when the device is folded. Business Insider published Samsung patents back in May showing a phone that can be folded into thirds, but the business news site noted that patents often change, and some are scrapped altogether.

The Galaxy Note 9 is also likely to be unveiled soon, as is a $300 Samsung speaker that's set to rival the Apple HomePod.

The Galaxy X will certainly be a nifty new invention, but it won’t come cheap. The Wall Street Journal reports the phone will set you back about $1500, which is around $540 more than Samsung’s current most expensive offering, the Galaxy Note 8.
