All The Digital Data In The World Is Equivalent To One Human Brain
From Popular Science:
If you could put all the data in the world onto CDs and stack them up, the pile would stretch from the Earth to beyond the moon, according to a new study. The world’s technological infrastructure has a staggering capacity to store and process information, reaching 295 exabytes in 2007, a reflection of the world’s almost complete transition into the digital realm. That's a number with 20 zeroes behind it, in case you're wondering.

Winter Scuttles Effort to Reach Ancient Arctic Lake
From CBS News:
In a race against the clock, Mother Nature won. A Russian team that has been toiling around the clock to pierce through to a sub-glacial lake in Antarctica is calling it quits - for now - because of harsh winter weather that's freezing their hydraulic tools.
The sub-glacial Lake Vostok is located at the bottom of a 12,000 foot-thick ice sheet in Antarctica but the project leaders reported the evacuation of its team 29.53 meters short of the final destination. They plan to resume their work next spring, when temperatures allow them to again use their drills. Lake Vostok has some of the lowest recorded temperatures found anywhere, with the thermometer going as low as -129 degrees Fahrenheit.

After Retiring from Government Service, Space Shuttles May Be Sold For Flights In Private Sector -- Popular Science
NASA contractor suggests private spaceflights starting in 2013.
A NASA contractor wants to go all Brett Favre on America’s space shuttles, pulling them out of retirement past their prime to keep them going, even if it’s to play for the other side.
United Space Alliance, which manages the shuttle program for NASA, wants to spend $1.5 billion annually to fly two missions a year from 2013 to 2017, using Endeavour and Atlantis. It would bridge the gap between the end of the shuttle program and the start of privately run space taxis, and help prevent American reliance on Russian Soyuz spacecraft.

A Satellite Network Is One Way To Bypass An Internet Shutdown
Online censorship and Internet kill-switches could meet their match if satellite-enabled services and ground peer-to-peer networks become more widespread in the future. That's the view of Kosta Grammatis, CEO and founder of ahumanright.org, who sees Internet access as a basic necessity.
An independent satellite operator could have kept Egyptian protesters online and connected to the outside world despite the Egyptian government's shutdown of Internet Service Providers (ISPs) this past week. Governments would find it difficult to jam an independent satellite signal across an entire country, Grammatis said in a TIME interview.

Is There Life Out There?
Hunting: Nasa's planet-hunting telescope is finding whole new worlds of possibilities in the search for alien life
Chances Of Finding Aliens Given A Boost After Nasa Finds Evidence Of Over 1,200 MORE Planets - And 54 Of Them May Be Able To Support Life! -- The Daily Mail
The chances of finding alien life were given a boost last night after Nasa revealed it had found evidence of more than 1,200 planets in orbit around far distant stars.
If the findings are confirmed, it will more than triple the number of known planets outside our own solar system in one fell swoop - and, amazingly, 54 of them could be able to support life.
Only two potentially habitable planets have previously been found outside earth's solar system, so Kepler chief scientist William Borucki said 54 is 'an enormous amount, an inconceivable amount'.

With Climate Change, Expect More Monster Winter Storms -- Live Science
No single weather event can be directly attributed to climate change. But as the globe warms up, Americans can expect more storms like the one bearing down on much of the United States, scientists say.
That's not because the Feb. 1 storm can be linked to rising atmospheric carbon dioxide levels or increasing global temperature – again, such a connection is impossible to make – but, according to climatologists, an increased propensity for winter storms is exactly what you'd expect in a warming world.

The Landscape Of Mars Is Actively Changing
Three images of the same location taken at different times show seasonal activity causing sand avalanches and ripple changes on a Martian dune. Every year, dune fields at high latitudes are covered by a seasonal polar cap of condensed carbon dioxide (dry ice). Sand sliding down the dune carves out new alcoves at the top and adds to the debris apron on the bottom. The top image was taken in the Martian summer when the dunes were free of seasonal dry ice. Spring found the region covered by a layer of seasonal ice (middle). Evaporation of this seasonal ice layer shows up as dark streaks of fine particles carried to the top of the ice layer by escaping gas. As the ice changes from solid to gas, gas flowing underneath destabilizes the sand and causes it to avalanche down the dune. The bottom image shows the resulting changes, revealed during the following summer after the ice was gone. New wind ripples can be seen on the debris apron. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter took these images, each showing an area of 285 x 140 meters, centered at 84 degrees North latitude and 233.2 degrees East longitude.

Space So Full Of Junk That A Satellite Collision Could Destroy Communications On Earth -- The Telegraph
Space is so littered with debris that a collision between satellites could set off an “uncontrolled chain reaction” capable of destroying the communications network on Earth, a Pentagon report warned.
The volume of abandoned rockets, shattered satellites and missile shrapnel in the Earth’s orbit is reaching a “tipping point” and is now threatening the $250 billion (£174bn) space services industry, scientists said.
A single collision between two satellites or large pieces of “space junk” could send thousands of pieces of debris spinning into orbit, each capable of destroying further satellites.

5,000 Years Of Egyptian Antiquities Are Now Being Looted Across Egypt
Egypt's Antiquities Fall Victim To The Mob -- Wall Street Journal
When Zahi Hawass, the secretary general of the Supreme Council of Antiquities, came to work at the Egyptian Museum on Saturday, he found that looters had broken in and beheaded two mummies—possibly Tutankhamun's grandparents—and looted the ticket booth. Reports indicate that middle-class Egyptians, the tourism police and later the military secured the museum. But now it appears that many other museum's and storehouses have been looted, along with archaeological sites. A vast, impoverished underclass seems less taken with either the nationalist narrative of Egyptian greatness that stretches back to the pharaohs, or the intrinsic value of antiquities for all humanity, and more intrigued by the possibility of gold and other loot. For his part, Mr. Hawass has now been appointed state minister for antiquities by President Hosni Mubarak.

My Comment: The focus of the media is on the Egyptian Museum in Cairo, and efforts to protect it. But the fact is that there are many more museums all across Egypt, and reports are now coming in that they are being looted. To say that this is a catastrophe is an understatement. Regardless of what is happening politically, years from now Egypt will be looking at what is happening today as a dark day in which a good portion of its historical past was looted and stolen.
Why Walking Will Boost Your memory
Forget the brain puzzles, mild exercise such as walking can boost brain volume and improve memory in older adults, researchers have found.
"With a limited investment of time and effort you can produce fairly dramatic improvements in memory and brain health," senior researcher Arthur Kramer, of the University of Illinois at Urbana-Champaign, told LiveScience. "You can roll back the clock about two years."

Shutting Down The U.S. Internet: A Doomsday Scenario
From CBS News:
For Americans addicted to Facebook and Google, a day without the Internet might seem to last forever, but the effect of going offline would be no less traumatic for the entire U.S. economy, experts say.
While the economy probably could reverse the damage from being offline a few days, every day without the Internet would be a step closer to calamity for manufacturing, finance and other sectors of the economy.

The Web Will Soon be Out of Addresses
The last big blocks of the net's dwindling stock of addresses are about to be handed out.
The event that triggers their distribution is widely expected to take place in the next few days.
When that happens each of the five regional agencies that hand out net addresses will get one of the remaining blocks of 16 million addresses.
The addresses in those last five blocks are expected to be completely exhausted by September 2011.

Rewriting History Of Man As A Global Species
Out Of Africa: Stone Tools Rewrite History Of Man As A Global Species -- The Independent
A stone-age archaeological site in the Arabian peninsula has become the focus of a radical theory of how early humans made the long walk from their evolutionary homeland of Africa to become a globally-dispersed species.
Scientists have found a set of stone tools buried beneath a collapsed rock shelter in the barren hills of the United Arab Emirates that they believe were made about 125,000 years ago by people who had migrated out of eastern African by crossing the Red Sea when sea levels were at a record low.

Is The PC On The Way Out?
Are Tablets Going To Kill The PC? -- Discovery Magazine
It would've been more appropriate to call this year's Consumer Electronics Show (CES) in Las Vegas the Consumer Tablet Show.
In the wake of Apple’s iPad 2010 success with sales topping 10 million units, competing companies rolled out more than 80 tablet devices at the January electronics tradeshow.
“At CES, it seemed like every major company introduced at least one new tablet to its line of products,” said Jonathan Strickland, technology expert who covered CES 2011 for HowStuffWorks.com and the TechStuff podcast.

My Comment: I am skeptical that this will happen. Computers are easier to use .... and quicker when it comes to work. Tablets will be predominant .... but killing the PC .... nah.
Identifying Skin Cancers With Laser Light

Yeah, you’ve been thinking about getting that thing checked out, but it’s just a mole right? Such is the problem with melanoma; it’s tough to know which spots on the skin are benign and which could be the hallmark of early-stage skin cancer. Most dermatologists still decide which moles require a biopsy by good old fashioned eye-balling, but a new device developed by researchers at British Colombia Cancer Agency (BCCA) could remove that guesswork, using a handheld laser to quickly identify problem spots that require closer examination.

Startling Images Which Show How Chimpanzees Mourn Their Dead
A Mother's Grief: The Startling Images Which Show How Chimpanzees Mourn Their Dead Just Like Humans -- The Daily Mail
Chimpanzees appear to mourn their dead infants just like humans, scientists have discovered.
Chimpanzee mothers establish close physical relationships with their young, carrying them for up to two years and nursing them until they are six.
But now scientists have filmed how one chimpanzee mother, whose 16-month-old infant died, apparently begins the grieving process.
It’s the latest evidence highlighting just how similar chimps and other great apes are to humans.

Asteroid Deflection: What If A Huge Asteroid Was Going To Slam Into Earth? -- Science Daily
ScienceDaily (Jan. 31, 2011) — So you think global warming is a big problem? What could happen if a 25-million-ton chunk of rock slammed into Earth? When something similar happened 65 million years ago, the dinosaurs and other forms of life were wiped out.
"A collision with an object of this size traveling at an estimated 30,000 to 40,000 mile per hour would be catastrophic," according to NASA researcher and New York City College of Technology (City Tech) Associate Professor of Physics Gregory L. Matloff. His recommendation? "Either destroy the object or alter its trajectory."
