The internet is ruled by a small number of massive corporations. Roger McNamee, Co-founder of Elevation Partners on CNBC, says, Google, Facebook, Amazon are increasingly just super-monopolies, especially Google … The share of the markets they operate in is literally on the same scale that Standard Oil had … more than 100 years ago—with the …
Jan. 10 (UPI) — By analyzing the unique rotation of FRB 121102, a fast radio burst discovered by Cornell astronomers, scientists have been able to study the nature of its cosmic origin.
While studying the giant pulse of radio waves, researchers realized the waves gyrate, or “twist and shout,” as they pass through a veil of magnetized plasma. The twists represent what’s called Faraday rotation, while the shouts describe the bursts.
By measuring these two phenomena, scientists can better understand the cosmic conditions that inspired the massive pulse of radio waves.

A little hBN in ceramics could give them outstanding properties, according to a Rice University scientist.
Rouzbeh Shahsavari, an assistant professor of civil and environmental engineering, suggested the incorporation of ultrathin hexagonal boron nitride (hBN) sheets between layers of calcium-silicates would make an interesting bilayer crystal with multifunctional properties. These could be suitable for construction and refractory materials and applications in the nuclear industry, oil and gas, aerospace and other areas that require high-performance composites.
Combining the materials would make a ceramic that’s not only tough and durable but resistant to heat and radiation. By Shahsavari’s calculations, calcium-silicates with inserted layers of two-dimensional hBN could be hardened enough to serve as shielding in nuclear applications like power plants.

Over the past year, Google has demonstrated its desire to step up its hardware game. The company bought HTC’s Pixel team for $1.1 billion, designed its own imaging chip for the Pixel 2 and also hired a key Apple chip designer. Bloomberg reports that in its bid to gain an edge on the competition, Google has quietly snapped up UK startup Redux, a small team focused on delivering sound and touch feedback via mobile displays.
According to filings, Google took control of the startup back in August and then subsequently shut down the company’s website. Previous demonstrations show Redux playing back music via a tablet device, which possesses tiny actuators that vibrate the screen and effectively turn it into a loudspeaker. By eliminating the need for smartphone speakers, Google may be able free up more space for batteries and other important components inside future smartphones.
Imagine you and a group of friends are at the peak of a mountain after a long hike. It’s sunset and the sky is alight; you want to take a photo. You pull out your smartphone, but instead of flipping it around to take a long-armed selfie, you unclip a tiny drone from the back of your phone, make it hover at the perfect height and snap a series of photos, no extendo-arms required.
With CES 2018 now in full swing, it’s time to explore what Intel, Samsung, Toyota, and other companies have in store for the future of consumer electronics.
The 2018 Consumer Electronics Show is now in full swing. Between now and Friday, January 12, all kinds of technology — both conceptual and practical — will be unveiled and trotted out in front of audiences. We’ve already written about what you can expect to see from CES 2018, but as day one draws to a close, it’s a good time to check-in on what’s already trending.
WiFi security hasn’t changed much since WPA2 came to be in 2004, and that’s becoming increasingly apparent when public hotspots are frequently risky and glaring exploits are all too common. It’s about to get a long-due upgrade, though: the Wi-Fi Alliance plans to roll out a WPA3 standard that addresses a number of weak points. For many, the highlight will be individualized data encryption. Even if you’re on an open public network, you won’t have to worry quite so much about someone snooping on your data.
You’ll also see safeguards even when people have terrible passwords, and a simplified security process for devices that have either a tiny display or none at all (say, wearable devices or smart home gadgets). And companies or governments that need stricter security will have access to a 192-bit security suite.
WPA3 should arrive sometime in 2018, and comes on the back of other improvements like more thorough testing to catch potential vulnerabilities before they require emergency patches. These initiatives aren’t going to guarantee airtight security when you’re at the coffee shop, but they could at least eliminate some of WiFi’s more worrying flaws.
