What's the No. 1 requested feature people want in an e-ink e-reader?

According to Barnes & Noble, it's an integrated light, which is why the company spent the last two years developing the new $139 Nook Simple Touch with GlowLight, available today for preorder and shipping in early May.

I had a chance to play around with the new Nook at a launch event in New York and, as you can see from the pictures, except for the gray border around the edge, it looks identical to the standard $99 Nook Simple Touch, which remains on the market. … Read more

A year ago, hedge fund manager Philip Falcone's LightSquared offered the Federal Communications Commission a huge opportunity to satisfy some of its most lofty wireless broadband goals. Today, the company is facing possible bankruptcy and only the slimmest chance of actually building its network, leaving policy makers in Washington focusing on alternatives.

Earlier this week, Falcone, whose hedge fund Harbinger Capital is the largest stakeholder in LightSquared, told Reuters that bankruptcy protection is one of several options he is considering as he tries to keep the company alive. LightSquared, which has been battling the GPS industry over claims that … Read more

Cree is leaning on high design to get LED lighting onto lamp posts.

The company today introduced new lines of streetlights that use long-lasting and energy-efficient LEDs, including AeroBlades lamps which are an array of LED light sources in blade-like strips.

Cree also updated its traditional LED streetlights for overhead lighting and developed a lamp with traditional bulb designed to fit into historic districts.

The products are the first since Cree, which makes LED light sources, purchased Ruud Lighting to expand its lighting fixture business. LEDs are a good fit for street lights in that they last longer than other … Read more

It may not be the first smartphone-microscope combo, but creators of the SkyLight adapter say their device is different: it doesn't use any optics.

Attach the base of SkyLight to a microscope and slide in a smartphone--most any smartphone actually, thanks to the mount's adjustable clips. Users -- whether students or scientists -- can then capture microscopic images and send them via e-mail or to the Web.

SmartPlanet visits with SkyLight creators Andy Miller and Tess Bakke for a hands-on look at the device.

This video originally appeared on SmartPlanet with the headline "SkyLight starts selling combo smartphone-microscope mount.&… Read more

In a famous surgery in the early 1900s, Canadian neurosurgeon Wilder Penfield, trying to treat epilepsy, found that stimulating specific neurons while patients were under local anesthesia caused them to vividly recall complex events. The mind, then, is based on matter, Penfield concluded.

Now researchers at MIT say they put this observation to the test in a rigorous study showing that the direct reactivation of specific hippocampus neurons can lead to very specific memory recall. And to do this, all they used was light.

"We demonstrate that behavior based on high-level cognition, such as the expression of a specific … Read more

Has the Federal Communications Commission finally learned its lesson on spectrum management?

The FCC began proceedings yesterday that could OK Dish Network's plan to use existing spectrum to build a terrestrial 4G LTE mobile broadband network. The rulemaking follows the agency's earlier rejection of Dish's request for a waiver of license conditions, which prohibit using the spectrum for anything other than satellite-based applications.

The decision to proceed with the slower but more formal process was certainly motivated in part by the recent fiasco involving LightSquared. In January 2011, the FCC granted LightSquared a waiver similar to the … Read more

LightSquared says it's not yet giving up its fight to build a nationwide 4G LTE network.

The company, which is backed by Philip Falcone's Harbinger Capital, has invested more than $4 billion into the network, which it hoped would be a wholesale alternative to wireless broadband networks run by AT&T and Verizon wireless. For the past year, the company has been fighting an uphill battle in Washington, D.C., where the GPS industry has rallied political support around its claims that LightSquared's network interferes with its receivers and therefore cannot be built.

So far, the … Read more

New experimental evidence is helping disprove last year's highly surprising finding of neutrinos breaking established physics laws by traveling faster than light.

The finding involved clocking the neutrinos--tiny, nearly massless subatomic particles--as they traveled from the CERN particle accelerator near Geneva to the Gran Sasso National Laboratory in Italy, about 730km away. An experiment called Opera found the neutrinos taking less time to arrive than light would, but now another Gran Sasso experiment, Icarus, showed neutrinos making the journey at a more sedate pace under light speed, CERN said.

That finding comes after news in February that a fiber-optic connection problem … Read more

A worldwide zombie invasion is the perfect hypothetical setting for survivalist tips, and Jeff and I can't help but explore a few of them after watching this week's episode of "The Walking Dead."

After we get that out our system, the rest of today's rundown consists of AOL laying off the majority of its AIM unit, waving goodbye to the printed Encyclopedia Britannica, and a city in the U.K. shaming away loitering youth with pink lighting that exposes acne.… Read more
