From Science Daily:

Science Daily (Jan. 18, 2010) — The Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, recently obtained the biggest fleet of so-called gliders in Europe. These instruments can explore the oceans like sailplanes up to a depth of 1000 metres. In doing so they only consume as much energy as a bike light. In the next years up to ten of these high-tech instruments will take measurements to better understand many processes in the oceans. Currently scientists and technicians prepare the devices for their first mission as a 'swarm' in the tropical Atlantic.

The Science Behind The Cell Phone Cancer Scare

studies have yet to find a link. Credit: Stockxpert

From Live Science:

Do cell phones cause brain cancer? There's no good reason to think they do.

But if we are to believe the gospel truth delivered by physicists that radio waves from cell phones simply aren't powerful enough to break chemical bonds, the trait of all cancer-causing mutagens, why then do very smart people — smarter than me, for sure — continue to investigate this matter?

No Bananas On My Space Flight

From New Scientist:

Astronauts experience weightlessness, and most of them also lose weight in space. Why? Because they are often nauseous, always busy, and the food on board their capsules, shuttles and space stations doesn't look, smell or taste like it does on Earth.

As a result, NASA has devoted years to creating foods that can travel safely into space and meet astronauts' nutritional needs while not making a mess of their spacecraft.

From The BBC:

Becoming the pilot of a spaceship may seem the stuff of science fiction, but it could be a regular job in just 20 years time, a report has concluded.

That is one of the findings of a government study into jobs of the future, which also suggests people will be employed to make human body parts.

It names 20 jobs that could be common by 2030, including "vertical farmers" growing food in multi-storey buildings.

It also says surgeons may be employed to give people extra memory capacity.

The Core Of Truth Behind Sir Isaac Newton's Apple

Sir Isaac Newton was said to have discovered gravity while
sitting in his mother's garden in Lincolnshire. PA.

From The Independent:

The manuscript that gave rise to one of science's best-known anecdotes is now online.

It is one of the most famous anecdotes in the history of science. The young Isaac Newton is sitting in his garden when an apple falls on his head and, in a stroke of brilliant insight, he suddenly comes up with his theory of gravity. The story is almost certainly embellished, both by Newton and the generations of storytellers who came after him. But from today anyone with access to the internet can see for themselves the first-hand account of how a falling apple inspired the understanding of gravitational force.

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.

Weekends Are Good For You, Study Finds

From Live Science:

Just about everybody – even workaholics – should look forward to the weekend, when most people get a mood boost, a new study suggests.

Participants in the study often reported better moods, greater vitality, and fewer aches and pains from Friday evening through Sunday afternoon as compared with the rest of the week.

"Workers, even those with interesting, high-status jobs, really are happier on the weekend," said study researcher Richard Ryan, a professor of psychology at the University of Rochester.
