Here Be Monsters: Study Identifies Likely Location of Merging Black Hole Giants

  Here Be Monsters: Study Identifies Likely Location of Merging Black Hole Giants Determining the precise location or home galaxy of these black hole pairs has multiple advantages for astrophysics. First, it would increase the odds of seeing light signals created by the merger of two black holes. While the black holes themselves are completely dark, nearby matter (such as a disk of gas and dust swirling around it) could radiate light. Studying this light could provide scientists with more information about these events.

Sprint and T-Mobile end merger negotiations

  Sprint and T-Mobile end merger negotiations Sprint and T-Mobile end merger negotiationsSprint Corp (S.N) and T-Mobile USA Inc (TMUS.O) said on Saturday that they officially broke off merger negotiations, ending months of back-and-forth talks that would have created the third-biggest U.S. wireless provider.

Aluminum foil can actually improve your wireless signal . Bust out the tinfoil, everyone.

And when SoundCloud hasn't had much success getting customers to bite, a good deal like this could go a long way toward improving the company's bottom line.

If you've ever thought of resorting to aluminum foil to redirect your home's poor WiFi signal, it turns out you're not actually that far off the mark. EurekAlert reported November 8 that researchers at Dartmouth College have discovered that 3D printed signal reflectors, consisting of a thin layer of metal and plastic, can drastically and cheaply improve the wireless signal around a home.

These experiments were based off the idea of using an aluminum soda can behind a router in order to direct the signal away from deadening walls and other obstructions. The team was able to analyze a space and create a custom reflector that would optimize the WiFi signal in that room. They then fed their data into a custom program called WiPrint that designed an optimal plastic reflector and created it using a 3D printer. The last step is to cover the object in aluminum foil and place it on the router. You can see a demonstration in the video below.

Its researchers have found a way to spin light into complex states that promise breakthroughs in multiple fields. Its researchers have found a way to spin light into complex states that promise breakthroughs in multiple fields. They've built metasurfaces whose elaborate optics combine two kinds of light momentum (orbital angular and spin angular) to send light into corkscrews, spirals or even fork-like shapes. If you want to change the light state, you just need to change the polarization of that light.

This solution solves multiple problems with WiFi signals. First of all, it's inexpensive; if you have access to a 3D printer, it will only run you about $35. Directional antennas cost a lot more than that. Second, it allows you control over your WiFi signal, which has more benefits than you think. Not only does it make sure you have signal in the rooms you need it in, but it allows you to cut off signal where you don't. This improves physical security, ensuring neighbors (and unsavory types) can't access your network.

The next step for the team is to figure out how to design reflectors that are made of a different material than 3D printed plastic. The idea is to eventually create an object that can actually change shape if the room's layout changes. This may not expand the coverage area of your router, but it will ensure that you'll get stronger signal in the areas you need it most.

I tried out Google’s translating headphones. Here’s what I found. .
Google’s Pixel Buds won’t put translators out of business, but they're better than a phrase book.The most important thing you should know about Pixel Buds is that their full features only work with Google’s newest smartphone, the Pixel 2. While they’ll function with other phones, you must have a Google Pixel phone — last year's Pixels, the Pixel 2 or Pixel 2 XL (which, buyer beware, have had some early quality-control issues) —  to access the Pixel Buds’ marquee feature: real-time translation.
