Scheme To 'Pull Electricity From The Air' Sparks Debate

The claim of electricity from the air as a renewable resource is controversial

From The BBC:

Tiny charges gathered directly from humid air could be harnessed to generate electricity, researchers say.

Dr Fernando Galembeck told the American Chemical Society meeting in Boston that the technique exploited a little-known atmospheric effect.

Tests had shown that metals could be used to gather the charges, he said, opening up a potential energy source in humid climates.

However, experts disagree about the mechanism and the scale of the effect.

Does Langage Influence Culture?

Lost In Translation -- Wall Street Journal

New cognitive research suggests that language profoundly influences the way people see the world; a different sense of blame in Japanese and Spanish.

Do the languages we speak shape the way we think? Do they merely express thoughts, or do the structures in languages (without our knowledge or consent) shape the very thoughts we wish to express?

Take "Humpty Dumpty sat on a..." Even this snippet of a nursery rhyme reveals how much languages can differ from one another. In English, we have to mark the verb for tense; in this case, we say "sat" rather than "sit." In Indonesian you need not (in fact, you can't) change the verb to mark tense.

Silicon Valley’s Dark Secret: It’s All About Age

From Tech Crunch:

An interesting paradox in the technology world is that there is both a shortage and a surplus of engineers in the United States. Talk to those working at any Silicon Valley company, and they will tell you how hard it is to find qualified talent. But listen to the heart-wrenching stories of unemployed engineers, and you will realize that there are tens of thousands who can’t get jobs. What gives?

The harsh reality is that in the tech world, companies prefer to hire young, inexperienced, engineers.

Ye Cannae Change The Laws Of Physics. Or Can You?

From The Economist:

RICHARD FEYNMAN, Nobel laureate and physicist extraordinaire, called it a “magic number” and its value “one of the greatest damn mysteries of physics”. The number he was referring to, which goes by the symbol alpha and the rather more long-winded name of the fine-structure constant, is magic indeed. If it were a mere 4% bigger or smaller than it is, stars would not be able to sustain the nuclear reactions that synthesise carbon and oxygen. One consequence would be that squishy, carbon-based life would not exist.

Earliest Fossil Evidence Of Humans In Southeast Asia?

Archaeologists excavating Callao Cave in the Philippines.
Armand Salvador Mijares

From Earth Magazine:

Modern humans reached the islands of Southeast Asia by approximately 50,000 years ago, but our ancestors’ journey was not easy. Even during times of low sea level, a voyage to some of these islands would have required crossing open water, leaving many scientists to wonder how humans arrived on the most isolated islands. Now the story is growing more complicated: A group of archaeologists has discovered a 67,000-year-old foot bone that they say represents the earliest-known presence of humans in the northern Philippines and may be among the oldest-known traces of modern humans in all of Southeast Asia — that is, if the bone truly belongs to Homo sapiens. The bone’s small size and unusual features make it difficult to determine exactly which species of Homo it was — Homo sapiens, Homo floresiensis or something else?

The U.S. Sniper's More Accurate, Quieter Rifle -- Popular Mechanics

Army Snipers in Afghanistan will receive an improved rifle this fall.

For snipers, every war is different. Recognizing the differences between conditions in Iraq and Afghanistan, the Army is now selecting a contractor to upgrade the 22-year-old Remington bolt-action rifle to become a more effective killing machine. The Army will pour about $5.6 million into upgrades to the M24, with the new gear expected to be delivered to troops by this fall. The M24's barrel is being modified to shoot heavier .300 Winchester Magnum rounds, instead of the 7.62mm NATO ammunition, which should extend the rifle's maximum effective range by hundreds of yards to a maximum of about 1400 yards. The suppressor will reduce the noise and flash of the gun so snipers can stay in their hiding positions much longer after they fire.

Both Siemens and GE bet on direct-drive generators.

Wind turbine manufacturers are turning away from the industry-standard gearboxes and generators in a bid to boost the reliability and reduce the cost of wind power.

Siemens has begun selling a three-megawatt turbine using a so-called direct-drive system that replaces the conventional high-speed generator with a low-speed generator that eliminates the need for a gearbox. And last month, General Electric announced an investment of 340 million euros in manufacturing facilities to build its own four-megawatt direct-drive turbines for offshore wind farms.

When Will We Be Able To Build Brains Like Ours?

Image: Henrik5000

From Scientific American:

Sooner than you think -- and the race has lately caused a 'catfight'.

When physicists puzzle out the workings of some new part of nature, that knowledge can be used to build devices that do amazing things -- airplanes that fly, radios that reach millions of listeners. When we come to understand how brains function, we should become able to build amazing devices with cognitive abilities -- such as cognitive cars that are better at driving than we are because they communicate with other cars and share knowledge on road conditions. In 2008, the National Academy of Engineering chose as one of its grand challenges to reverse-engineer the human brain. When will this happen? Some are predicting that the first wave of results will arrive within the decade, propelled by rapid advances in both brain science and computer science. This sounds astonishing, but it’s becoming increasingly plausible. So plausible, in fact, that the great race to reverse-engineer the brain is already triggering a dispute over historic “firsts.”
