Facebook Wants To Control The Web, Like It Or Not

From InfoWorld:

Facebook wants to dictate how you log in and share content across the Web. Should you let them? Cringely says nyet.

Mark Zuckerberg may look and sound like the irritatingly self-satisfied rich kid you always hated in high school, but I’ll say this for him: He’s got cojones the size of tractor tires.

Facebook just made a play to take over the entire Web -- or at least, the parts that get the most traffic -- via its new "social graph,” officially unveiled at this week’s F8 confab.

Experimental Explanation Of Supercooling: Why Water Does Not Freeze In The Clouds

From Science Daily:

ScienceDaily (Apr. 23, 2010) — Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today. A good example of this phenomenon is found everyday in meteorology: clouds in high altitude are an accumulation of supercooled droplets of water below their freezing point.

Flying Car Could Transform Warfare

From Live Science:

The Defense Advanced Projects Agency (DARPA) has cleared the Transformer (TX) program for takeoff. If it flies, by 2015 U.S. soldiers will be able to ride into battle aboard a four-person flying car that can cruise in the air like an airplane, drive on the ground like an SUV, rove 250 miles on one tank of fuel and not require a runway to get airborne.

DARPA, the Department of Defense office that is tasked with exploring futuristic technologies that may have military applications, held an industry day workshop for companies earlier this year to solicit proposals for developing a prototype vehicle. Proposals are due May 27.

From The Guardian:

Climate modeller Andrew Weaver launches libel action in Canada for publishing 'grossly irresponsible falsehoods'.

One of the world's leading climate scientists has launched a libel lawsuit against a Canadian newspaper for publishing articles that he says "poison" the debate on global warming.

In a case with potentially huge consequences for online publishers, lawyers acting for Andrew Weaver, a climate modeller at the University of Victoria, Canada, have demanded the National Post removes the articles not only from its own websites, but also from the numerous blogs and sites where they were reposted.

IPad’s Rivals Are On The March

From Times Online:

As Apple prepares to unleash the iPad in Britain, its rivals are preparing their fightback, rushing to create and release their own tablet computers, devices already dubbed the “iPad killers”.

Moreover, the attack on the iPad is coming on several fronts. The mobile phone maker Nokia is believed to be planning a similar machine designed mainly to read electronic books. Microsoft is flirting with the idea of creating a tablet. Even Google could enter the fray with a slate of its own.

Obama’s NASA Blueprint Is Challenged In Congress

From The New York Times:

WASHINGTON — President Obama may have hoped that a speech a week ago at the Kennedy Space Center would sway skeptics to his proposed space policy, but a Congressional hearing on Thursday gave little signs that the lines of contention have shifted yet.

Opponents like Richard C. Shelby, the Republican senator from Alabama where NASA’s Marshall Space Flight Center has been leading the design of the Ares I rocket that the Obama administration would like to cancel, continued to denounce Mr. Obama’s plans. Those plans call for ending NASA’s current Constellation program that was to send astronauts back to the moon and turning to private companies for transportation into orbit.

From New Scientist:

On 28 December 1963, Randy Gardner, a 17-year-old schoolboy in San Diego, California, got up at 6 am feeling wide awake and raring to go. He didn't go back to sleep again until the morning of 8 January 1964. That's 11 days without sleep.

Gardner's 264 hours remains the longest scientifically verified period without sleep, breaking the previous record of 260 hours. It was described in a 1965 paper by sleep researcher William Dement of the Stanford University School of Medicine in California, who stayed awake with Gardner for the final three days.

From Popular Science:

Your chance to spot 50 years' worth of sneakily concealed aliens.

Over the past decade, those who wished to contribute to SETI's mission of locating life elsewhere in the universe could leave their computers on running a special screensaver and donate their unused computing power to the cause. Now, SETI director Jill Tarter is asking people around the globe to get more involved in the Search for Extraterrestrial Intelligence by opening up SETI's servers to the public calling for a worldwide, open source contribution to the search.

In Deep Sea, Waves With a Familiar Curl

From The New York Times:

Scientists exploring the deep sea have discovered a distinctive kind of breaking wave. The finding reveals the presence of a subtle new force that can stir the dark seabed, and it helps to explain some of the nuances of planetary recycling and the provision of food to abyssal life.

The discovery also illustrates the radical nature of the insights that lay behind the start of the scientific revolution some four centuries ago.

Wow! Celebrate Hubble’s 20th With Best Space Image Ever

From Wired Science:

We were already dreading the day Hubble dies, but this mind-blowing new image released to celebrate the space telescope’s 20th anniversary makes us wish for eternal life for the famous satellite even more.

This new gem rivals what may be Hubble’s most famous image, a shot of the Pillars of Creation taken in 1995. The shot above is of a star-forming region in the Carina Nebula. The enormous pillar of gas and dust is 3 light-years tall. The seam in the middle is the result of new stars forming and emitting powerful gas jets that are ripping the pillar apart.

Dream A Little Dream Of Recall

From Science News:

Nap-time reveries may show that sleeping brain is making memories.

People who have nap-time dreams about a task that they’ve just practiced get a big memory boost on the task upon awakening, Harvard researchers report.

Those who dream about anything else have no such enhanced recall, the team reports in a paper published online April 22 in Current Biology. Neither do those who stay awake, even if they think about the task.

Toilet Paper Problem: Good Raw Material Being Wiped Out

From Live Science:

A shortage of high-quality paper for recycling could mean scratchy toilet tissue. To keep consumers happy and avoid any chafed rear ends, companies are now on a quest to find new paper supplies, according to an article in the current issue of Chemical & Engineering News (C&EN).

The problem: Consumers once could fill up large bins with their recycled newspapers, magazines and print paper. But as electronic communication surges, these sources of recycled paper are becoming scarce.

From Epicenter:

Apple appears to have been right in betting that people would embrace a big version of the iPod Touch; the increased sense of intimacy with no keyboard or mouse chaperons is palpable. But even larger touchscreens, like the one the Finnish company MultiTouch let us play around with last week, can track each fingertip of a large group of people — a key distinction that enables a more social set of behaviors, because multiple people can use them at the same time.

From New Scientist:

Zi Ye and Hammad Khalid of the Human Media Lab at Queen's University in Kingston, Ontario, Canada, have devised a way of using a shoulder-mounted projector system to display - and play - a game on a bendy A4-sized sliver of plastic. Sensors in the screen allow gameplay to be controlled by bending, shaking or tapping it.

A prototype of the system, called Cobra, was shown last week at the Computer-Human Interaction meeting in Atlanta, Georgia. It runs games on a computer housed in a shoulder pouch, while the pouch's straps hold a small projector that shines images onto the flexible screen, held by the gamer.
