Why We Can't Do 3 Things At Once

When humans pursue two goals A and B concurrently, the two frontal lobes divide for representing the two goals and related actions simultaneously. The anterior most part of the frontal lobes enables to switch back and forth between the two goals, i.e. executing one goal while maintaining the other one on hold. This inter-hemispheric division of labor explains why humans appear unable to accurately carry out more than two tasks at one time. Credit: Etienne Koechlin, INSERM-ENS, Paris, France, 2010.

From Live Science:

For those who find it tough to juggle more than a couple things at once, don't despair. The brain is set up to manage two tasks, but not more, a new study suggests.

That's because, when faced with two tasks, a part of the brain known as the medial prefrontal cortex (MFC) divides so that half of the region focuses on one task and the other half on the other task. This division of labor allows a person to keep track of two tasks pretty readily, but if you throw in a third, things get a bit muddled.

Apollo 13: Australia's Untold Story

From Cosmos:

MELBOURNE: Forty years ago, on 13 April 1970, NASA's worst nightmare became reality when there was an explosion aboard Apollo 13.

And in Australia, scientists and engineers at the Parkes radiotelescope - celebrated in the 2000 movie The Dish - had to find a way to stay in contact with the stranded astronauts.

"The expertise and skills of Australian scientists proved vital in the tracking of the spacecraft - without which the rescue would not have succeeded," said John Sarkissian, the operations scientist at Parkes.

April 16, 1943: Setting The Stage for World’s First Acid Trip

1943: Albert Hofmann accidentally discovers the psychedelic properties of LSD.

From Wired:

Hofmann, a Swiss chemist, was researching the synthesis of a lysergic acid compound, LSD-25, when he inadvertently absorbed a bit through his fingertips. Intrigued by the stimulating effects on his perception, Hofmann decided further exploration was warranted. Three days later he ingested 250 micrograms of LSD, embarking on the first full-fledged acid trip.

Google's Q1 Earnings Show Continued Ad Growth

From CNET:

Google continues to demonstrate that an online advertising recovery is well under way, at least when it comes to search advertising.

For its fiscal first quarter, which ended March 31, Google on Thursday reported revenue of $6.77 billion, up 23 percent from the same period last year. Financial analysts evaluate Google's revenue performance by excluding traffic-acquisition costs paid to Google's partners, which totaled $1.71 billion. That puts net revenue at $5.06 billion, slightly ahead of analyst estimates of $4.95 billion for the quarter.

DARPA Spills Details On Its Plans For The Transformer TX Flying Car

Transformer Car Oh hi DARPA, you called?

From Popular Science:

DARPA didn't reveal much at first about its "Transformer TX" program aimed at developing a flying car for the military. But now the full proposal has been published, and shows that the Pentagon agency hopes to get a prototype airborne by 2015, The Register reports.

The mad scientists want a vertical-takeoff vehicle that handles like an off-road-capable SUV on the ground, and can cruise like a light single-engine aircraft at altitudes of up to 10,000 feet.

Facebook Attacked Over Refusal To Install Panic Button

From Times Online:

Britain's online child protection agency attacked Facebook yesterday for its continued refusal to install a panic button on its site.

Richard Allan, head of policy for the social networking site in Europe, said it had agreed a series of measures allowing users in the UK to report concerns about child safety directly to the Child Exploitation and Online Protection centre (Ceop).

The new system flags up Ceop after users have already gone through Facebook's own reporting procedure.

Navy SEALs Recognize Anger More Quickly

From Live Science:

The brains of elite soldiers can respond faster to signs of anger than normal, which could help them detect threats and make the difference between life and death when under fire.

The differences in the brains of those who excel in extreme circumstances are poorly understood. Such research might help improve military performance, explained neuroscientist Alan Simmons at the University of California at San Diego.

Body Heat: Sweden's New Green Energy Source

Commuters at Stockholm's Central station. Jim Stenman

From Time Magazine:

It's 7:30 a.m. on a wintry morning in downtown Stockholm and a sea of Swedes are flooding Central Station to catch a train to work. The station is toasty thanks to the busy shops and restaurants and the body heat being generated by the 250,000 commuters who crowd Scandinavia's busiest travel hub each day. This heat used to be lost by the end of the morning rush hour. Now, however, engineers have figured out a way to harness it and transfer it to a newly refurbished office building down the block. Unbeknownst to them, these sweaty Swedes have become a green energy source: "They're cheap and renewable," says Karl Sundholm, a project manager at Jernhusen, a Stockholm real estate company, and one of the creators of the system.

On Its Way To Britain: The Killer Asian Hornet Which Threatens Our Native Honeybees

An Asian hornet is seen in a beehive in south western France. The pest has decimated hives in Europe and is on its way to Britain

From The Daily Mail:

Giant hornets with a searing sting and a hearty appetite for honeybees are making a beeline for Britain.

The Asian hornet is four times the size of our native honeybees and is armed with a sting that has been compared to a hot nail being hammered into the body.

Aggressive and belligerent, it preys on honeybees, 'picking them off' as they leave their hive, until the colony is so exhausted that the hornets can move in and ransack it.

Yahoo, Feds Battle Over E-Mail Privacy

From Threat Level:

Yahoo and federal prosecutors in Colorado are embroiled in a privacy battle that’s testing whether the Constitution’s warrant requirements apply to Americans’ e-mail.

The legal dust-up, unsealed late Tuesday, concerns a 1986 law that already allows the government to obtain a suspect’s e-mail from an ISP or webmail provider without a probable-cause warrant, once it’s been stored for 180 days or more. The government now contends it can get e-mail under 180-days old if that e-mail has been read by the owner, and the Constitution’s Fourth Amendment protections don’t apply.

BRACE yourself for more winters like the last one, northern Europe. Freezing conditions could become more likely: winter temperatures may even plummet to depths last seen at the end of the 17th century, a time known as the Little Ice Age. That's the message from a new study that identifies a compelling link between solar activity and winter temperatures in northern Europe.

Is Earth Shaking More?

From Live Science:

As the numbers of buried or dead continue to climb from today's 6.9-magnitude earthquake in China, an event so close on the heels of the devastating Chile and Haiti earthquakes, you might wonder if Earth is shaking more lately. Perhaps, scientists say, but not unusually so.

Seismic activity may be higher in recent years than the long-term average, but it's still not out of the normal range, the experts contend.
