Twisted Physics: Scientists Create Light Knots

By reflecting a laser beam from a specially designed hologram (shown here as the colored circle), physicists created knots of dark filaments (represented by the colored knot). Credit: Mark Dennis.

From Live Science:

Like your shoelaces or electrical cords, light can get twisted into knots. Now, scientists have used a computer-controlled hologram and theoretical physics to turn a light beam into pretzel-like shapes.

The twisted feat not only led to some pretty cool images, but the results have implications for future laser devices, the researchers say.

Turkey Blocking 3,700 Websites: OSCE

From Reuters:

VIENNA (Reuters) - Europe's main security and human rights watchdog said Monday Turkey was blocking some 3,700 Internet sites for "arbitrary and political reasons" and urged legal reforms to show its commitment to freedom of expression.

Milos Haraszti, media freedom monitor for the 56-nation Organization for Security and Cooperation in Europe (OSCE), said Turkey's Internet law was failing to preserve free expression in the country and should be reformed or abolished.

"In its current form, Law 5651, commonly known as the Internet Law of Turkey, not only limits freedom of expression, but severely restricts citizens' right to access information," Haraszti said in a statement.

Space Shuttles For Sale

From New Scientist:

Space shuttle for sale, fully loaded, air conditioning, one careful owner. It's the ultimate bargain. NASA has cut the price of a space shuttle to $28.8 million. The vehicles will go on sale after they finish constructing the International Space Station, scheduled to be later this year. The New York Times reports that NASA had hoped to get $42 million for each vehicle but lowered the cost in the hope of sealing a deal. It has three to sell, although one of these, Discovery, is already promised to the Smithsonian National Air and Space Museum in Washington DC.

McAfee: China Attacks A 'Watershed Moment'

From CNET:

The China-based cyber attacks on Google and other companies were "a watershed moment in cybersecurity," according to an executive at computer security company McAfee.

"I believe this is the largest and most sophisticated cyberattack we have seen in years targeted at specific corporations," McAfee Chief Technology Officer George Kurtz wrote on his blog Sunday. "While the malware was sophisticated, we see lots of attacks that use complex malware combined with zero day exploits."

Feet Hold The Key To Human Hand Evolution

Scientists simulated the change from an ape-like hand to a human-like hand.

From The BBC:

Scientists may have solved the mystery of how human hands became nimble enough to make and manipulate stone tools.

The team reports in the journal Evolution that changes in our hands and fingers were a side-effect of changes in the shape of our feet.

This, they say, shows that the capacity to stand and walk on two feet is intrinsically linked to the emergence of stone tool technology.

Hexapod Robot Moves In The Right Direction By Controlling Chaos

From Scientific American:

Given that robots generally lack muscles, they can't rely on muscle memory (the trick that allows our bodies to become familiar over time with movements such as walking or breathing) to help them more easily complete repetitive tasks. For autonomous robots, this can be a bit of a problem, since they may have to accommodate changing terrain in real time or risk getting stuck or losing their balance.

From Times Online:

A WARNING that climate change will melt most of the Himalayan glaciers by 2035 is likely to be retracted after a series of scientific blunders by the United Nations body that issued it.

Two years ago the Intergovernmental Panel on Climate Change (IPCC) issued a benchmark report that was claimed to incorporate the latest and most detailed research into the impact of global warming. A central claim was the world's glaciers were melting so fast that those in the Himalayas could vanish by 2035.

Another Sign That America's Science Position In The World Is Changing

U.S. Keeps Science Lead, But Other Countries Gain -- Wall Street Journal

The U.S. remains the world's science and technology leader, but other countries are gaining ground, the National Science Board said Friday in its biennial report on science and engineering.

The U.S. accounted for nearly a third of $1.1 trillion spent on research and development globally in 2007, minted more science and engineering doctorates than any other country, and led the world in innovative activity. Efforts by China and other developing Asian countries to boost their science and engineering capabilities are bearing fruit, however, and the gap between them and the U.S., though still wide, is narrowing.

Popular interest in history is peaking like perhaps never before in the 21st century.

TV historians such as Simon Schama and David Starkey are household names. Dan Brown's Lost Symbol dominated the fiction chart in the past year and all of the novels shortlisted for the Man Booker prize in 2009 were set against historical backdrops, with the winner – Hilary Mantel’s Tudor England-based Wolf Hall – proving the most popular Booker prize winner of all time.

The combination of widespread deforestation and the recent earthquake in Haiti could lead to more landslides in the already hard-hit country, scientists say (Haiti map).

(Read "Haiti Earthquake 'Strange,' Strongest in 200 Years.")

Many of Haiti's people, the poorest in the Americas, routinely cut down trees for fuel—either to burn "raw" or turn into charcoal.

As a result, the destruction of Haiti's natural forests is almost total, making the Caribbean country one of the most deforested in the world.

Voodoo Wasps That Could Save The World

$5 Million Will Buy You Your Own Jet Fighter

$5M Buys the Ride of Your Life -- Autopia

The Russian Sukhoi SU-27 has a top speed of Mach 1.8 (more than 1,300 mph) and a thrust-to-weight ratio greater than 1:1. In other words, it can accelerate while climbing straight up.

Last week, we told you about a cool DIY jet. If you like the idea of a jet but not the thought of doing it yourself, John Morgan has you covered. He’s got a pair of beautifully restored Sukhoi SU-27 Flanker jets. They’re first-rate pieces of Soviet-era hardware designed to go head-to-head with the McDonnell Douglas F-15 Eagle.

Electromagnetic Manufacturing: It's A Knockout

From The Economist:

Engineers find a new way to punch holes through steel.

ELECTROMAGNETIC pulses (EMPs) are usually associated with warfare. The idea is to use a blast of energy to fry the enemy’s computers and telecommunications gear. One common way proposed to do this is with an atomic bomb. In a less extreme fashion, however, EMPs have peaceful uses. They are already employed industrially to shape soft and light metals, such as aluminium and copper. Now a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, has found a way to use an EMP device to shape and punch holes through industry’s metallic heavyweight—steel. This could transform manufacturing by doing away with the need to use large, heavy presses to make goods ranging from cars to washing machines.
