Amazing bridge

This is a wildlife bridge in the Netherlands. Wildlife bridges are designed to help animals cross busy highways in safety. They don't just protect wildlife from being hit by cars - they also connect fragmented habitats and help populations intermingle and breed.
The Netherlands is leading the way in designing these bridges. The country is home to more than 600 similar crossings.

Robotic metal band ...

Did you ever wonder what Danny Carey would sound like if he had 4 arms?
How about if Angus Young had 78 fingers? Imagine what Robert Trujillo would sound like if he was actually made of metal?
Well, wonder no more, meatbags.
Compressorhead is the worlds heaviest metal band.
Stickboy, fingers, and bones are guaranteed to shake and rattle the world of meatbag music.
Stickboy (drums) was created to exacting specifications. 4 arms, 2 legs, 1 head, no brain. he plays a Pearl 14 piece kit with double kick. stickboy junior, the bastard child of an unknown mother takes control of the hihat shuffle. inception date 2007
Fingers (guitar) joined stickboy in 2009 and brings 78 purpose built fingers, enough to play the entire fret board and pluck.
Bones (bass) is the highest precision bass player in known existence, and the youngest member of the band. inception date 2012.
Standaside meatbags. Oil is thicker than blood.

How We Will Terraform Mars

NASA's latest Mars rover, Curiosity, is currently its way to Mars, on a mission to explore whether life could exist there. If we're going to colonize Mars — and some scientists say we must — it's likely that we'll start by terraforming. Terraforming, or planetary engineering, is the process of altering the climate of a planet to be more hospitable to life and human exploration. Of all the bodies in the solar system, Mars is by far the best candidate. Here's how that would work.


Once A Wet, Warm Planet
To understand how Mars might have a habitable future, it's important to understand a bit about Mars' past.
Mars' geological history is divided into three ages, which are from oldest to youngest the Noachian, the Hesperian and the Amazonian. The Noachian epoch, ranging from about 4.1 to about 3.7 billion years ago, is characterized by heavy asteroid bombardment and abundant surface water. This is the so-called "warm, wet" period. The Hesperian, ranging from 3.7 to somewhere between 1.7 and 3.0 billion years ago, is characterized by heavy volcanic activity and massive water flow. The Hesperian was an intermediate age between the warm wet Noachian and the the cold, dry Amazonian, which is the Mars we know today as being not the kind of place to raise a kid.
It is this unique history that makes Mars such an attractive candidate for terraforming. Unlike the other bodies in the solar system, Mars has a history (ancient though it may be) of being far more Earthlike than anywhere else in the solar system short of Earth itself. The proposals for terraforming the other bodies in the solar system are all highly theoretical, involving massive energy flux and near magical technology like changing planetary orbits, speeding up planetary rotation, sequestering hundreds of bars of atmosphere (1 bar = atmospheric pressure at sea level on Earth) or constructing planet-wrapping Dyson spheres to prevent atmospheric escape.
By contrast, Mars, with its 24 hr 37 minute day, relatively abundant water ice and history of warmer wetter conditions seems more within the grasp of near future human civilization to terraform. Add to this the fact that not-too-crazily-optimistic estimates of Mars' current conditions suggest that increasing the atmospheric pressure and temperature to more life friendly conditions may be more a matter of a nudge than a shove and it's easy to see why this world holds such fascination for would-be planetary engineers.
How We Will Terraform Mars Why Did Mars Die?
So, what happened on Mars? Why did this once warm and inviting place, with enough atmospheric pressure and a high enough temperature to support liquid water, become a frozen rock with an atmosphere too thin to support even water ice? The answer boils down to...or rather, freezes out to...volcanism and bombardment.
In the Noachian period, Mars experienced a high frequency of asteroid impacts. The energy and volatile gas introduced into the Martian environment by the Noachian bombardment helped maintain the warm, wet climate and the thick atmosphere.

For Girls only

Have heck loads of money and don't know what to do with it?! Make a shirt out of GOLD!

A wealthy man splashed out Rs 12 lakhs on a solid gold shirt in the hope it will attract female attention. No kidding!

'I know I am not the best looking man in the world but surely the woman are going to notice me with this' he explained a local newspaper in Pune.

Do you think the ladies will be dazzled with this shirt that screams out loud for attention?

Gamera II hits new high with unofficial human-powered helicopter altitude record (video)


DNP Altera Human Heli
The University of Maryland team responsible for the Gamera II human-powered helicopter NAA flight time record may be on its way to bagging another one -- this time for altitude. With new freshman pilot Henry Enerson spinning the cranks, the gigantic four-rotor design ascended to eight feet, an unexpectedly lofty level, according to the team. The well-controlled 25 second flight was far less than the record 49.9 seconds Gamera achieved earlier, but the new altitude bodes well for its upcoming Sikorsky Prize attempt. That $250,000 award, unclaimed since 1980, requires a 10-foot altitude to be maintained for one minute, and now looks to be distinctly in the UMD group's sights. Check the video after the break, and marvel at the ungainly quadrocopter's latest aerial exploit.


Depression and stress can shrink your brain

WASHINGTON: Severe depression or chronic stress can cause your brain to shrink and lead to emotional and cognitive impairment, a new study has claimed. A team of researchers led by Yale scientists discovered that one reason for this condition is a single genetic switch that triggers loss of brain connections in humans and depression in animal models.
The findings, published in the journal 'Nature Medicine' , show that the genetic switch known as a transcription factor represses the expression of several genes that are necessary for the formation of synaptic connections between brain cells, which in turn could contribute to loss of brain mass in the prefrontal cortex of the brain.
"We wanted to test the idea that stress causes a loss of brain synapses in humans ," said senior author Ronald Duman, the Elizabeth Mears and House Jameson professor of psychiatry and professor of neurobiology and of pharmacology.
"We show that circuits normally involved in emotion , as well as cognition, are disrupted when this single transcription factor is activated ," Duman said.
Scientists analysed tissue of depressed and non-depressed patients donated from a brain bank and looked for different patterns of gene activation. The brains of patients who were in depression exhibited lower levels of expression in genes that are required for function and structure of brain synapses.
Lead author and postdoctoral researcher H J Kang discovered that at least five of these genes could be regulated by a single transcription factor called GATA1

Inactivity 'killing as many as smoking'

A lack of exercise is now causing as many deaths as smoking across the world, a study suggests.
The report, published in the Lancet to coincide with the build-up to the Olympics, estimates that about a third of adults are not doing enough physical activity, causing 5.3m deaths a year.
That equates to about one in 10 deaths from diseases such as heart disease, diabetes and breast and colon cancer.
Researchers said the problem was now so bad it should be treated as a pandemic.
And they said tackling it required a new way of thinking, suggesting the public needed to be warned about the dangers of inactivity rather than just reminded of the benefits of being active.
