Brute Force: Humans Can Sure Take A Punch
From Live Science:
The human body can take a remarkable amount of punishment, given bones made of one of the strongest materials found in nature. At the same time, even an unarmed person can inflict an astonishing amount of damage with the proper training.
So how much does it take to crack a bone? And how much mayhem can a person deal out? In an era when "extreme fighting" has become a popular phenomenon, scientists are testing the extremes that athletes at the peak of their game can reach in order to help the rest of us.

From CBS News:
NOAA May Limit Sonar Tests, though Another Case Heads to Court.
Whales and the U.S. Navy have tangled repeatedly over the past years over charges that the Navy’s sonar exercises disorient or injure whales and other marine mammals. Now, whales in the Pacific appear to have a new champion: the National Oceanic and Atmospheric Administration, which is considering limiting the Navy’s sonar tests in certain marine mammal “hot spots.”

From Technology Review:
An earlier measure of treatment could improve patients' prognosis.
When it comes to aggressive cancers, in the brain or lung for example, oncologists know that the sooner they can determine whether a treatment is unsuccessful, the sooner they can reevaluate and, if necessary, prescribe a new course of action. But typically, it takes two months or more to do the before-and-after comparisons that help determine whether a tumor is shrinking. Now an Israeli company called Aposense says it may have found a way to drastically speed up the process: an imaging marker that, when used with PET scans, indicates the presence of dying cells.

Police Want Backdoor To Web Users' Private Data
From CNET News:
Anyone with an e-mail account likely knows that police can peek inside it if they have a paper search warrant.
But cybercrime investigators are frustrated by the speed of traditional methods of faxing, mailing, or e-mailing companies these documents. They're pushing for the creation of a national Web interface linking police computers with those of Internet and e-mail providers so requests can be sent and received electronically.

No (Primordial) Soup For You: Origins Of Life Were Not What You Think
From Discovery News:
The predominant theory of the origin of life would make a terrific setting for a space horror movie, or a particularly tense episode of Star Trek: picture early Earth, a noxious place devoid of oxygen, its young oceans choked with some kind of indiscernible ooze.
Depending on how you like your origin stories, a thunderstorm passes overhead, and lightning crackles into the broth, pouring forth ever bigger organic molecules until -- presto! -- virus-sized strands of RNA and the first replicating life is formed.

DARPA's Robotic Ghost Ships Will Stalk Submarines
From Popular Science:
Ships that appear in perfect working order except for a missing human crew would normally raise suspicions that something has gone terribly wrong, possibly in the vicinity of the Bermuda Triangle. Yet an unmanned frigate is exactly what DARPA's mad scientists at the Pentagon have ordered, according to The Register. The automated ships' mission would have it spending months cruising the seas unmanned, on the hunt for ghostly enemy submarines.

NASA's New Mission: Space To Thrive
From The Economist:
A plan to overhaul America’s space agency is long overdue.
IN 2004 George Bush announced a plan for America’s space agency, NASA, to return to the moon by 2020, land there, explore the surface and set up a base. The moon would then serve as a staging post for a journey to Mars. It was, unfortunately, unclear how this modest proposal would be paid for and, as work began and costs spiralled, the “vision” seemed more science fiction than science.

Suspected Asteroid Collision Leaves Odd X-Pattern Of Trailing Debris
This is a NASA Hubble Space Telescope picture a comet-like object called P/2010 A2, which was first discovered by the LINEAR (Lincoln Near-Earth Asteroid Research program) sky survey on January 6. The object appears so unusual in ground-based telescopic images that discretionary time on Hubble was used to take a close-up look. This picture, from the January 29 observation, shows a bizarre X-pattern of filamentary structures near the point-like nucleus of the object and trailing streamers of dust. The inset picture shows a complex structure that suggests the object is not a comet but instead the product of a head-on collision between two asteroids traveling five times faster than a rifle bullet (5 kilometers per second). Astronomers have long thought that the asteroid belt is being ground down through collisions, but such a smashup has never before been seen. (Credit: NASA, ESA, and D. Jewitt (UCLA))

The 'New' NASA Will Look Back At Earth
From Live Science:
NASA's new proposed budget will in part shift the space agency's focus from landing people on the moon back to Earth, with more money slated to go to projects that will help us understand our planet's climate and even plans to re-launch the carbon observatory that failed to launch last year.
The 2011 proposed budget for NASA, announced on Monday, cancels the Constellation program to build new rockets and spacecraft optimized for the moon, but increases NASA's overall budget by $6 billion over the next five years. Of that $6 billion, about $2 billion will be funneled into new and existing science missions, particularly those aimed at investigating the Earth sciences, particularly climate.

Google Shows Off Chrome OS Tablet Ideas
From CNET News:
Who could resist the months of hype that paved the way for Apple's iPad debut last week? Apparently not Google, which has shown its interest in tablet computing with its browser-based Chrome OS.
On Monday, Glen Murphy, a user interface designer for Google's Chrome browser and the Chrome operating system based on it, pointed to image and video concepts of a Chrome OS-based tablet that went live two days before the iPad launch. Apparently nobody noticed initially, because only now did Murphy tweet, "Apparently our tablet mocks have been unearthed."
The site also shows the array of devices Google envisions for Chrome OS.

The Pursuit Of Intelligence In Computer Science
What actually constitutes an objective pattern of cognition in machines that we will recognize as intelligent is extremely vague and constantly being rewritten. Steve Dunning/Getty Images
From Discovery News:
We can’t give machines intelligence until we can figure out what roles creativity, inspiration and curiosity should play.
Since the dawn of high tech electronics and robotics, we’ve heard an awful lot about artificial intelligence and countless tales about how it may just decide to enslave us all one of these days, or fuse with humanity into an unrecognizable homunculus of men, women, children and machines as in the end of Isaac Asimov’s classic short story The Last Question, which is probably my favorite science fiction tale for it’s amazing scope and it’s bizarre climax. But when we actually drill down to the actual requirements for making machines endowed with the kind of computing abilities we’d call intelligence, we’ll find that the definition of what actually constitutes an objective pattern of cognition we will recognize as intelligent is extremely vague and constantly being rewritten.

NASA Budget Creates Uncertainty In Clear Lake
From Houston Chronicle:
Change came to Washington a year ago with the election of President Barack Obama, and one year later it is thundering through Houston's space community like a shuttle's sonic boom.
The totality of impacts from Obama's proposed NASA budget for Houston, the Clear Lake community surrounding Johnson Space Center and even for the astronauts themselves is still far from certain.
Space agency officials declined Tuesday to even confirm that NASA's astronaut corps would continue after the space shuttle retires within the next year.

China's Power Boom Means West May Swap Oil Dependency For Green Tech Dependency
From Popular Science:
President Obama made it clear in his State of the Union Address last week that he fears the American economy is on the brink of missing out on a green tech boom that could propel us out of our current financial mess and into the coming century, and it appears his concern is well-placed. China leapfrogged Denmark, Germany, Spain and the U.S. to become the world's largest maker of wind turbines last year, and 2010 is shaping up to be another banner year. For China that is, not for the West.

Neuron Breakthrough Offers Hope On Alzheimer’s And Parkinson’s
From Times Online:
Neurons have been created directly from skin cells for the first time, in a remarkable study that suggests that our biological makeup is far more versatile than previously thought.
If confirmed, the discovery that one tissue type can be genetically reprogrammed to become another, could revolutionise treatments for conditions such as Parkinson’s disease and Alzheimer’s, opening up the possibility of turning a patient’s own skin cells into the neurons that they need.

Apple iPad May Ship With Webcam
From Wired Science:
Close scrutiny of the iPad which Steve Jobs presented at Apple’s special event last week shows what may be webcam, tucked away in the black screen bezel just like it is on the MacBook Pro.
A screen-grab from the official video of the event shows nothing but a small dot above the screen, opposite the home button. Taken alone, this isn’t much, but compare this with the picture of the iPad leaked just hours before the event (below). If you remember, these showed an iPad locked down in a security frame, and you could clearly see the camera in the bezel. I even pointed out the cutout in the frame that let us see the webcam.

Save the Ozone Layer, Give Global Warming A Boost?
From The National Geographic:
While most of the world has warmed, parts of the southern hemisphere have remained stubbornly cold—oddly enough because of a gaping hole in the ozone layer. Now new research shows that all the efforts made by scientists and environmental advocates to close the hole may actually increase warming throughout the entire southern hemisphere.
That's because, for decades, brighter summertime clouds, created by the hole, have reflected more of the sun's rays, acting as a shield against global warming.

From The New Scientist:
"IN MONTH XI, 15th day, Venus in the west disappeared, 3 days in the sky it stayed away. In month XI, 18th day, Venus in the east became visible."
What's remarkable about these observations of Venus is that they were made about 3500 years ago, by Babylonian astrologers. We know about them because a clay tablet bearing a record of these ancient observations, called the Venus Tablet of Ammisaduqa, was made 1000 years later and has survived largely intact. Today, it can be viewed at the British Museum in London.

Spray-On Miracle Could Revolutionise Manufacturing
From The Independent:
Liquid glass sounds like the stuff of sci-fi. But can it really live up to the hype?
It sounds too good to be true: a non-toxic spray invisible to the human eye that protects almost any surface against dirt and bacteria, whether it is hospital equipment and medical bandages or ancient stone monuments and expensive fabrics.
But true it is. The spray is a form of "liquid glass" and is harmless to living things and the wider environment. It is being touted as one of the most important, environmentally-friendly products to emerge from the field of nanotechnology, which deals in objects at the molecular end of the size scale.

From The Telegraph:
A cat with an uncanny ability to detect when nursing home patients are about to die has proven itself in around 50 cases by curling up with them in their final hours, according to a new book.
Dr David Dosa, a geriatrician and assistant professor at Brown University, said that five years of records showed Oscar rarely erring, sometimes proving medical staff at the New England nursing home wrong in their predictions over which patients were close to death.
The cat, now five and generally unsociable, was adopted as a kitten at the Steere House Nursing and Rehabilitation Centre in Providence, Rhode Island, which specialises in caring for people with severe dementia.

So All These Climate Revelations Were A Dastardly Foreign Plot -- A Commentary
From The Independent:
It hasn't occurred to King that the emails might have been leaked by an insider
It was the Russians. Or possibly the Chinese. No, wait, it was the Americans. Yes, our very own version of Inspector Clouseau is on the case of the leaked emails from the University of East Anglia's Climatic Research Unit.
Yesterday Sir David King, Tony Blair's former chief scientific advisor, told this newspaper: "It was an extraordinarily sophisticated operation. There are several bodies of people who could do this sort of work. These are national intelligence agencies... there is the possibility that it could be the Russian intelligence agency." However, King goes on to suggest that the expense of such an operation would be too great for the entire Russian state to undertake: "In terms of the expense, there is the American lobby system, which is a very likely source of finance, so the finger must point to them."

How To Fall 35,000 Feet—And Survive
From Popular Mechanics:
You're six miles up, alone and falling without a parachute. Though the odds are long, a small number of people have found themselves in similar situations—and lived to tell the tale. Here's PM's 120-mph, 35,000-ft, 3-minutes-to-impact survival guide.
You have a late night and an early flight. Not long after takeoff, you drift to sleep. Suddenly, you’re wide awake. There’s cold air rushing everywhere, and sound. Intense, horrible sound. Where am I?, you think. Where’s the plane?
You’re 6 miles up. You’re alone. You’re falling.
Things are bad. But now’s the time to focus on the good news. (Yes, it goes beyond surviving the destruction of your aircraft.) Although gravity is against you, another force is working in your favor: time. Believe it or not, you’re better off up here than if you’d slipped from the balcony of your high-rise hotel room after one too many drinks last night.

The Brain: What Is The Speed Of Thought?
From Discover Magazine:
Faster than a bird and slower than sound. But that may be besides the point: Efficiency and timing seem to be more important anyway.
When Samuel Morse established the first commercial telegraph, in 1844, he dramatically changed our expectations about the pace of life. One of the first telegraph messages came from that year’s Democratic National Convention in Baltimore, where the delegates had picked Senator Silas Wright as their vice presidential nominee. The president of the convention telegraphed Wright in Washington, D.C., to see if he would accept. Wright immediately wired back: No. Incredulous that a message could fly almost instantly down a wire, the delegates adjourned and sent a flesh-and-blood committee by train to confirm Wright’s response—which was, of course, the same. From such beginnings came today’s high-speed, networked society.

Charting The Winners And Losers In Obama’s Science Budget
From Wired Science:
President Obama’s administration revealed its new budget Monday, and it increases funding for nearly all areas of science.
The largest raise went to the National Institutes of Health, which added $1 billion dollars to an already hefty budget. With the boost, the NIH would receive $32.1 billion in total funding. Only the Centers for Disease Control would receive less money than last year, although the cut is small. NASA, the Department of Energy’s Office of Science, and the National Science Foundation, as well as smaller research efforts at the National Institute for Standards and Technology and Department of Agriculture, would also get bumps.

NASA Budget: Constellation Officially Canned, But The Deep-Space Future Is Bright
The Ares I-X The Constellation Program rockets will fly no more, but "aggressive" research into heavy-lift rockets should take us closer to manned missions in deep space. NASA
From Popular Science:
Rumors circulated last week, but now it’s official: NASA won’t be sending manned missions back to the moon any time soon. But in what may seem like a gutting of NASA moon- and Mars-based ambitions there is a silver lining: a $6 billion investment in helping private industry bring their space launch vehicles up to human-rated capacity and a smattering of modest robotic precursor missions to the moon, Mars, Martian moons or the Lagrange points that should set the stage for later manned missions far beyond low-earth orbit.

Sea Level In Israel Has Been Rising And Falling Over The Last 2,500 Years
Rising and falling sea levels over relatively short periods do not indicate long-term trends. An assessment of hundreds and thousands of years shows that what seems an irregular phenomenon today is in fact nothing new," explains Dr. Dorit Sivan, who supervised the research.

From Science Daily:
Science Daily (Feb. 1, 2010) — The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels, most of the time below the present-day level. This has been shown in a new study supervised by Dr. Dorit Sivan, Head of the Department of Maritime Civilizations at the University of Haifa. "Rises and falls in sea level over relatively short periods do not testify to a long-term trend. It is early yet to conclude from the short-term increases in sea level that this is a set course that will not take a change in direction," explains Dr. Sivan.

Unlike conventional computers, which store each piece of data as a single value (either zero or one), quantum processors can take on multiple values simultaneously, which is why they are so efficient. Or rather why they would be, if we could figure out how to build them. So engineers in the field are abuzz about two major advances toward the creation of a practical quantum computer.

What The iPad Means For The Future Of Computing
From Gadget Lab:
When I picked up my iPhone over the weekend, I had an epiphany. I was using the LinkedIn app to confirm an invitation to connect, and it hit me: This is the future of mobile computing, the mobile web — the mobile experience.
No, I’m not saying the LinkedIn app is the future per se (that’d be silly), but rather the overall concept of it. The LinkedIn iPhone app is, in my opinion, better than the actual LinkedIn.com website. Same goes for the Facebook app compared to Facebook.com.

World's Most Powerful Laser To Trigger Fusion Reaction This Year
From The Telegraph:
A pivotal step in the march towards fusion power, the ''holy grail'' of sustainable clean energy, could be taken this year.
Scientists in the US are preparing for the dramatic moment when the world's most powerful laser unleashes the nuclear force that lights up the sun and achieves ''ignition''.
At that moment, 192 laser beams housed in a building the size of three football pitches will focus on a target the size of a peppercorn to trigger a self-sustaining fusion reaction.

Obama To Scrap Nasa Moon Mission In Favour Of Private 'Space Taxis'
Farewell Orion? The Contellation space programme looks set to be scrapped. There had been plans to use the Orion module to ferry astronauts to the ISS, like in this artist's impression
From The Daily Mail:
American dreams of putting another man on the Moon were dashed last night as President Obama announced a spending freeze to help combat a £1trillion U.S. budget deficit.
NASA's plan to launch a series of new manned Moon missions was one of 120 government-funded programmes shelved.
The Constellation Project, started by George Bush, was supposed to restore America's reputation as a pioneer in human exploration and anticipated landings on Mars by the middle of the century.

New Infographic Visualizes The Space Debris Cloud Surrounding Earth
From Popular Science:
My debris field is bigger than yours.
Space debris remains one of the biggest challenges for a space-faring humanity in the 21st century, as even the smallest pieces can pose a serious threat to satellites, manned spacecraft and the International Space Station. Now our friends at Fast Company have stumbled on a nifty infographic by Austrian designer Michael Paukner that lays out the space clutter situation more clearly.

No Moon Program For NASA
The battle over space has begun. And it's likely to be brutal.
The Obama administration is attempting to kill NASA's ambitious back-to-the moon program, an effort that carried the imprimatur of George W. Bush. The Constellation program had already run through about $9 billion to develop a new crew capsule, Orion, and a new rocket, the Ares 1. Both are vaporized by Obama's new NASA strategy.

WikiLeaks Whistleblower Site In Temporary Shutdown
From BBC News:
WikiLeaks, a whistleblower website that allows people to publish uncensored information anonymously, has suspended operations owing to financial problems.
Its running costs including staff payments are $600,000 (£377,000), but so far this year it has raised just $130,000 (£81,000).
WikiLeaks has established a reputation for publishing information that traditional media cannot.
The website claims to be non-profit and relies on donations.
A statement on its front page says it is funded by "human rights campaigners, investigative journalists, technologists and the general public".
