Electrical stimulation to the brain speeds up learning

Air Force operator receiving transcranial direct current stimulation (TDCS) to accelerate learning.

By running a mild electric current through the brains of pilots during lessons, Air Force researchers have cut their personnel’s learning time in half.  Pilots were being taught how to identify targets using drones—the practice is increasingly important to modern warfare and one which, due to its difficulty, is holding back the deployment of drones. Caffeine and other stimulants have been tested to aid learning but none work as well as two milliamperes of direct current for 30 minutes to pilot’s brains during training sessions on video simulators.

Google drops ‘Renewable Energy Cheaper than Coal’ research project

google-alta-iv-wind-farm-construction-photo-001

Did Google give up on the planet?

Google is quite a big proponent of renewable energy. They have made all kinds of investments in wind, solar, geothermal, etc. Some are to generate clean energy for their own needs, others are more akin to financing deals to help big wind and solar farms get built. In any case, it is very commendable work and if more big corporations had the long-term vision of Google, the world would definitely be in better shape.

But sadly, one of their most promising clean energy projects has just gotten the axe. Renewable Energy Cheaper Than Coal which was launched in 2007 via the Google.org Foundation, aimed to drive down the cost of renewable energy via R&D efforts until it was cheaper than coal, the magic point at which adoption would reach escape velocity…

Malls go Big Brother with holiday shopping cell phone tracking

mall_cell_trackingggg

Where are you going and where have you been? No need to tell me, I already know.

With mobile phone privacy in the forefront of our minds, it was a bit disconcerting to hear that this holiday season (Black Friday through New Years) certain malls will be tracking shoppers’ phones. Right now, just two US malls have said they will be anonymously tracking visitor’s phones, the Promenade Temecula in Temecula, California and the wonderfully-named Short Pump Town Center in Richmond, Virginia.

A notice was posted at the Promenade stating that anonymous data will be collected using the signals from visitors’ mobile phones. The data will be anonymized and is collected using a number of “monitoring units” placed around the mall. The purpose of the data collection, according to both the mall’s signage and website is to “enhance the shopping experience,” something we’re not quite sure all the visitors will appreciate as much as the malls might hope…

Cyber Monday piggybacks on social media to become top online shopping day

cyber-monday-facebook-users-graph-done-21

When the term Cyber Monday was coined in 2005, the Monday after Thanksgiving was the 12th biggest online shopping day of the year. That year, Facebook had 5.5 million users and Twitter didn’t exist. In 2010, Cyber Monday was the #1 biggest online shopping day of the year, with sales topping $1 billion. I believe the growth of social media and the importance of Cyber Monday are correlated because peer -to-peer sharing of deals and owned marketing channels like Facebook Pages and Twitter accounts are bringing promotions directly to where users spend their time online.

The red line is where Cyber Monday ranked among the top online shopping days (from comScore press releases) for that year. Aside from 2008, which is an outlier due the recession, there is a trend in Cyber Monday popularity growing along with Facebook users…

House built on a Southern Calif. volcano.

Not every day you come across a unique home that looks like a UFO.  And you certainly wouldn’t come across one that is built on top of a volcano.  But there is a curious dwelling located between Las Vegas and Los Angeles that is sitting atop a volcano.  To be precise, the home is located in Newberry Springs, CA on top of a volcanic cinder cone.
