Mystery Solved! Find Out Why Google Used A Doodle Of A UFO On Its Search Engine

Doodle mystery: Google used the image of a UFO on its logo, sparking mass internet speculation and rumours on Twitter and Facebook

From The Daily Mail:

Google bamboozled its users today by displaying the symbol of a UFO on its search engine page.

The website featured the classic image of a flying saucer shining a beam of light onto the middle of the classic logo.

It usually displays images that mark anniversaries or key events on its home page but its selection this time seemed a total mystery.

Clicking on the link only led to the results for 'unexplained phenomena', adding to the confusion which soon spread around the world.

Astronauts Take a Break From Busy Space Mission

From Space.com:

Astronauts took a hard-earned break from work aboard the International Space Station Friday as they hit the midpoint of a busy mission to boost the outpost's science gear and supplies.

The 13 astronauts aboard the docked station and shuttle Discovery had a half-day off from their joint mission, time enough to gaze down at their home planet or simply enjoy flying in weightlessness.

"Sometimes, you've just got to look out the window and enjoy the view," shuttle astronaut Jose Hernandez told reporters in a televised interview this week. "It's just breathtaking and I can't describe it with words. It's just indescribable."

Chemical Neurowarfare

From Ryan Sager - Neuroworld:

Imagine a future where the Iranian regime didn’t need to spend weeks in the streets beating, killing, and jailing protesters to put down the reform movement. Imagine in this future that the beatings would be replaced with something gentler, but ultimately more sinister: non-lethal, weaponized drugs designed to decrease aggression and increase trust.

That’s the future imagined and fretted over in an opinion piece (non-gated, samizdat version here) and editorial (PDF) in the current issue of Nature.

Your Brain Is Organized Like a City

Brains and cities, as they get bigger, do so based on similar mathematical rules. Image credit: Credit: Rensselaer/Mark Changizi

From Live Science:

A big city might seem chaotic, but somehow everything gets where it needs to go and the whole thing manages to function on most days, even if it all seems a little worse for the wear at the end of the day. Sound a bit like your brain?

Neurobiologist Mark Changizi sees strikingly real similarities between the two.

Changizi and colleagues propose that cities and brains are organized similarly, and that the invisible hand of evolution has shaped the brain just as people have indirectly shaped cities. It's all driven by the need for organization and efficiency, the researchers say.

A Giant Fingerprint On Mars: High Res Camera Reveals Details Just 3ft Across On Red Planet

(Click Image To Enlarge)
Planet print: This picture was taken in a crater near Fan in the Coprates Region of Mars. The giant fingerprint-like shape was created by possible evaporites - sediments formed by the evaporation of water

From The Daily Mail:

This striking range of dunes and craters appears to form a giant cosmic fingerprint on the surface of the Red Planet.

Scientists believe the undulating ground reveals global climate changes that took place on Mars over the past few million years.

The area is in the Coprates region, a large trough that forms part of the Valles Marineris - a system of canyons stretching thousands of miles along Mars' equator.

The whitish areas could be evaporites - mineral sediments left behind when salt water evaporates. Such deposits would be of great interest as they indicate potential habitats for past martian life.

Prehistoric Hand Axes Older Than Once Thought

Oldest Old World Tools A collection of prehistoric stone hand axes appears above. When first discovered, most researchers thought that the hand axes were made between 500,000 and 200,000 years ago. However, a new study contends that they are in fact much older -- possibly the oldest hand axes in Europe. Michael Walker

From Discovery News:

Sept. 3, 2009 -- Europe's Stone Age has taken an edgy turn. A new analysis finds that human ancestors living in what is now Spain fashioned double-edged stone cutting tools as early as 900,000 years ago, almost twice as long ago as previous estimates for this technological achievement in Europe.

If confirmed, the new dates support the idea that the manufacture and use of teardrop-shaped stone implements, known as hand axes, spread rapidly from Africa into Europe and Asia beginning roughly 1 million years ago, say geologist Gary Scott and paleontologist Luis Gibert, both of the Berkeley Geochronology Center in California.

The Singularity And The Fixed Point -- A Commentary

From Technology Review:

The importance of engineering motivation into intelligence.

Some futurists such as Ray Kurzweil have hypothesized that we will someday soon pass through a singularity--that is, a time period of rapid technological change beyond which we cannot envision the future of society. Most visions of this singularity focus on the creation of machines intelligent enough to devise machines even more intelligent than themselves, and so forth recursively, thus launching a positive feedback loop of intelligence amplification. It's an intriguing thought. (One of the first things I wanted to do when I got to MIT as an undergraduate was to build a robot scientist that could make discoveries faster and better than anyone else.) Even the CTO of Intel, Justin Rattner, has publicly speculated recently that we're well on our way to this singularity, and conferences like the Singularity Summit (at which I'll be speaking in October) are exploring how such transformations might take place.

New Hope For Aids Vaccine As Scientists Find 'Achilles Heel'

From Times Online:

The search for an HIV vaccine has taken a major step forward with the discovery of a potential Achilles heel of the virus that causes Aids.

Two powerful antibodies that attack a vulnerable spot common to many strains of HIV have been identified, improving the prospects for a vaccine against a virus that affects an estimated 33 million people and kills over 2 million each year.

The discovery is important because it highlights a potential way around HIV’s defences against the human immune system, which have so far thwarted efforts to make a workable vaccine. The hope is that a vaccine that stimulates the production of these antibodies could remain effective against HIV even as the virus mutates.

Diesel Exhaust Is Linked To Cancer Development Via New Blood Vessel Growth

New research shows that diesel exhaust can induce the growth of new blood vessels that serve as a food supply for solid tumors. (Credit: iStockphoto)

From Science Daily:

ScienceDaily (Sep. 2, 2009) — Scientists have demonstrated that the link between diesel fume exposure and cancer lies in the ability of diesel exhaust to induce the growth of new blood vessels that serve as a food supply for solid tumors.

The researchers found that in both healthy and diseased animals, more new blood vessels sprouted in mice exposed to diesel exhaust than did in mice exposed to clean, filtered air. This suggests that previous illness isn’t required to make humans susceptible to the damaging effects of the diesel exhaust.

But mice fed the same high-fat diet during hours they should have been sleeping put on 48 percent compared to the weight they started with.

While the results would have to be replicated on humans to see if the effects are the same, researchers suspect they are.

From Popular Science:

The ancient Greeks thought an excess of bile could make you angry or melancholy, but Julian Zhu thinks the digestive juice could improve your smile. Zhu, a chemist at the University of Montreal, hit upon the idea while developing a bile-acid-based gel for tissue repair. He found that combining modified bile acids with silica created a hard plastic—perfect for patching broken pearly whites. The bile plastic matches the durability of plastic composite fillings and is more resistant to cracks. And it doesn’t leach mercury, as many commonly used metal fillings do. Bile occurs naturally in the body, so it wouldn’t cause any harm if the fillings were to decompose over time.

Google's Gmail Goof-Up

From Business Week:

The Web company initially offered little explanation for its e-mail failure; government may think twice before trusting it with vital tasks, says Computerworld.

It's too bad the National Transportation Safety Board can't investigate Google to find out just why Gmail crashed Tuesday as Google's explanations for its outages (via its dashboard) are short and kindergarten-like.

The NTSB would seek out the root cause of the outage, hold hearings and issue a report with recommendations for fixing the problem. But Google follows the standard operating practice of cloud and SaaS (Software-as-a-Service) providers, and that is to tell customers as little as possible about an outage. They treat their customers like dumb bunnies.

From The New York Times:

The human-driven buildup of heat-trapping greenhouse gases in the atmosphere appears to have ended a millenniums-long slide toward cooler summer temperatures in the Arctic, the authors of a new study report.

Scientists familiar with the work, to be published Friday in the journal Science, said it provides fresh evidence that human activity is not only warming the globe, particularly the Arctic, but could even fend off what had been presumed to be an inevitable descent into a new ice age over the next several dozen millenniums.

The reversal of the slow cooling trend in the Arctic, recorded in samples of layered lakebed mud, glacial ice and tree rings from Alaska to Siberia, has been swift and pronounced, the team writes.

In a study published online in Genome Research, scientists have made a crucial discovery of genes that have evolved in humans after branching off from other primates, opening new possibilities for understanding what makes us uniquely human.

What Happens When an Astronaut Sneezes?

No kidding! This CDC photograph captured a sneeze in progress, revealing the plume of salivary droplets as they are expelled in a large cone-shaped array from this man's open mouth. The flu virus can spread in this manner and survive long enough on a doorknob or countertop to infect another person. It dramatically illustrating the reason you should cover your mouth when sneezing or coughing to protect others from germ exposure, health officials say. It’s also why you need to wash your hands a lot, on the assumptions others don’t always cover their sneezes. Credit: CDC/James Gathany .

From Live Science:

Best to do the sneezing inside a shuttle or the space station, not on a spacewalk, when it can get real messy, with goo sprayed all over the inside of the helmet's "windshield."

Lately astronauts have been complaining about stuffy heads up there on the International Space Station. NASA doesn't think they have colds, though. Rather, the effects have more to do with pockets of carbon dioxide generated when they gather in groups, space station flight controller Heather Rarick said.

Space Mission To Mercury: How An Ion Engine Works

Photo courtesy NASA
This image of a xenon ion engine, photographed through a port of the vacuum chamber where it was being tested at NASA's Jet Propulsion Laboratory, shows the faint blue glow of charged atoms being emitted from the engine. The ion propulsion engine is the first non-chemical propulsion to be used as the primary means of propelling a spacecraft.

From The Telegraph:

The solar electric propulsion systems – or ion engines - which will power the next generation of spacecraft to Mercury and beyond are ten times more efficient than conventional rocket engines.

In an ion engine the gas xenon is pumped through a chamber where xenon atoms are stripped of an electron, becoming electrically charged ions, and drift towards two grids a millimetre apart.

The grids are fed with two thousand volts – in space this power will come from paper-thin solar panels spanning 26m. As the ions pass through the electrified grids they accelerate to up to 50km a second and shoot from the rear in a parallel beam.
