Which ear you hold your cell phone to may reveal brain dominance

It has long been understand that right-handed people -- who make up about 90 percent of the population -- have left-hemisphere dominant brains, and left-handed people the reverse. But the division of labor isn't actually that simple. For some 95 percent of righties, the left hemisphere almost exclusively handles language and the right emotion and image processing, while for lefties, only 20 percent experience such strict division.

Now there may be a new way, apart from handedness, to determine one's cerebral dominance: the cell phone.

In a new study out of Henry Ford Hospital in Detroit, published in JAMA Otolaryngology-Head & Neck Surgery, … Read more

How injectable nanogel could help fight diabetes

For diabetics who have to constantly manage their blood-sugar levels, insulin works. The problem is, many people with Type 1 diabetes have to prick their fingers multiple times a day to monitor their levels, and inject themselves with insulin when those levels are too high. And they don't always administer the right amount at the right time.

Researchers at the Massachusetts Institute of Technology and Boston Children's Hospital hope to automate insulin delivery with a novel nanotech approach that involves injecting a gel that detects blood-sugar levels and secretes insulin when needed -- with a single injection doing do the trick for as many as 10 days.… Read more

3D scanning shows a butterfly's metamorphosis

Thanks to the magic of dissection, we have a pretty good idea of the changes that occur when a caterpillar spins its chrysalis and enters its metamorphosis -- the developmental stage that sees it move from the juvenile larval stage to the gorgeous adult life of a butterfly.

However, as you might have already guessed, dissection destroys the specimen, meaning that researchers are unable to follow the full development of a creature. We do know that the caterpillar will use enzymes to break down some of its proteins to reform; Scientific American called this a cocoon full of "caterpillar soup." However, scientists have performed research revealing that while some breakdown occurs, the idea of caterpillar soup is mostly wrong (but still gross).

Using micro-computed tomography, or micro-CT scanning, which uses X-ray imaging to re-create 3D cross-sections of the scanned object, Tristan Rowe and Russell Garwood from the U.K's University of Manchester and Thomas Simonsen from London's Natural History Museum have discovered exactly what happens to a painted lady butterfly inside the chrysalis. … Read more

Google quantum computer lab to study artificial intelligence

Google is opening a new research lab to see if a quantum computer can solve problems too taxing for traditional computers.

Hosted by NASA's Ames Research Center, the new Quantum Artificial Intelligence Lab will be home to a quantum computer made by D-Wave Systems. Operated by the Universities Space Research Association, the supercomputer will be available to researchers around the world to work on their own projects.

The goal, as stated in a Google blog posted today, is "to study how quantum computing might advance machine learning."

Traditional computers are limited, as they think in terms of … Read more

Allure Energy latest to file infringement suit against Nest

Allure Energy sued Nest Labs yesterday, claiming that the company's much-celebrated Nest Learning Thermostat infringed on its patent.

Filing the suit in the United States District Court for the Eastern District of Texas, the Austin, Texas-based Allure alleged that its patent for the invention of an "Auto-adaptable energy management apparatus" trumped Nest's right to develop, market, and sell a smart thermostat.

Allure said it first began designing its product, which is known as EverSense, in 2009, and filed it patent application in 2010. The company said in a release that it also got a patent for &… Read more

$325,000 stem cell hamburger to be eaten soon

The race for a lab-grown meat alternative has been on for years. Modern Meadow, for example, has gone after a type of 3D-printed meat using bioprinting techniques. Dutch tissue engineer Mark Post is using stem cells to make a lab-grown hamburger, one that may be actually going down someone's gullet very soon.

Post's Cultured Beef Project has been in development at Maastricht University in the Netherlands for some time thanks to $325,000 in funding from an anonymous donor. Cow muscle stem cells are grown into miniscule strips of tissue. Each strip can take several weeks to grow. It takes 20,000 of these to make a single hamburger. It's a time-consuming and expensive product at this stage of the project.… Read more

U.S. State Department latest to crack down on 3D-printed guns

The latest governmental attack on 3D printed guns came from the U.S. State Department on Thursday.

In a letter sent to Defense Distributed, a nonprofit advocating for the creation of 3D printed firearms, the State Department demanded the removal from a public Web site of a set of 3D files used to print gun components. The State Department said that the online dissemination of the files could violate restrictions on exporting guns covered by International Traffic in Arms Regulations (ITAR)

Defense Distributed founder Cody Wilson said he obeyed the federal directive. It followed the announcement yesterday by California state … Read more

Why fear of 3D-printed guns is overblown

Despite politicians lining up to regulate 3D printed guns, and a new directive from the U.S. State Department arguing that disseminating 3D files for such weapons may violate weapons export rules, some think that it may all be much ado about nothing.

On Thursday, Forbes reported, the State Department demanded that Defense Distributed, a nonprofit dedicated to creating 3D printed guns, take down a set of files that theoretically enable anyone to print their own firearm.

"The government says it wants to review the files for compliance with arms export control laws known as the International Traffic in … Read more

Landsat watches over the Earth, documenting 28 years of change

NASA's Landsat 5, which recently set a Guinness World Record for the "Longest Operating Earth Observation Satellite," has been delivering high-quality, global data of Earth's land surface for 28 years and 10 months.

Using the annual Landsat satellite imagery captured since 1984, Google has created dramatic composites, alongside other Google Earth satellite imagery, depicting our changing world, the death and growth of natural lands, and humans' impact on the landscape.

The animated GIFs shown here chronicle the development and destruction of life on Earth, pulsing like a living being, with forests receding, water evaporating, and cities … Read more

3D holograms show if baby's smiling in the womb

Remember back in the olden days, when you had to wait till your baby came out of the womb to start determining whose nose and chin it had?

Pioneer, maker of speakers, receivers, and headphones, is moving into the in-utero-baby-picture realm with 3D holograms that give a remarkably detailed look at an infant's early visage.

The company does that using a full-color hologram printer. The device, which fits into a briefcase, can record a full color card-size hologram in 120 minutes, and a single-color hologram in 90 minutes. … Read more
