'Eureka machine' works out laws of nature | Science | guardian.co.uk

Scientists have created a "Eureka machine" that can work out the laws of nature by observing the world around it - a development that could dramatically speed up the discovery of new scientific truths.

The machine took only hours to come up with the basic laws of motion, a task that occupied Sir Isaac Newton for years after he was inspired by an apple falling from a tree.

Scientists at Cornell University in New York have already pointed the machine at baffling problems in biology and plan to use it to tackle questions in cosmology and social behaviour.

FT.com / UK - Robot achieves scientific first
A laboratory robot called Adam has been hailed as the first machine in history to have discovered new scientific knowledge independently of its human creators.

Adam formed a hypothesis on the genetics of bakers' yeast and carried out experiments to test its predictions, without intervention from its makers at Aberystwyth University.

The result was a series of "simple but useful" discoveries, confirmed by human scientists, about the gene coding for yeast enzymes. The research is published in the journal Science.

North Korea 'begins fuelling rocket for launch' | World news | guardian.co.uk

North Korea has begun fuelling a rocket in readiness for a launch that could take place within days, further raising tensions between Pyongyang and Washington, it was reported today.

A senior US official told Reuters that Washington was exerting "maximum effort" to avert the rocket launch.

However, the official added: "The general expectation is that this launch is going to proceed."

The US president, Barack Obama, and the South Korean president, Lee Myung-bak - both of whom are in London for the G20 financial summit - agreed on the need for a "stern, united response" if the rocket was launched, a spokesman for Lee said.

North Korea's military has threatened immediate retaliation if "even the slightest effort" is made to intercept the rocket.

North Korea could launch missile on April 4 | World | Reuters

WASHINGTON/SEOUL (Reuters) - North Korea's missile preparations suggest Pyongyang could launch a satellite into space as early as Saturday, an American defence official said on Thursday as the U.S. military monitored the situation.

At the United Nations, Japan's U.N. ambassador, Yukio Takasu, said his country would request an emergency meeting of the Security Council to discuss a possible response if North Korea launched the long-range missile in the coming days.

The United States and others have threatened North Korea with punishment if they launch the long-range missile.

"They're doing everything consistent with the launch of a space vehicle on April 4," the U.S. defence official told Reuters on condition of anonymity.

Kidnappers free one Red Cross worker in Philippines | World | Reuters

MANILA (Reuters) - An Islamic militant group on Thursday freed a Filipina Red Cross worker held captive for two-and-a-half months in the southern Philippines, but continued to hold her two European colleagues, officials said.

The Abu Sayyaf rebel group had threatened to behead one of the hostages on Tuesday unless government troops withdrew from much of Jolo island, but the ultimatum was ignored.

President Gloria Macapagal Arroyo said the release of the Filipina engineer, Mary Jean Lacaba, was "confirmation that we should always stand behind our policy of dealing firmly with any form of lawless behaviour."

BBC NEWS | Technology | Virus battery could 'power cars'

Viruses have been used to help build batteries that may one day power cars and all types of electronic devices.

The speed and relatively cheap cost of manufacturing virus batteries could prove attractive to industry.

Professor Angela Belcher, who led the research team, said: "Our material is powerful enough to be able to be used in a car battery."

The team from MIT in the US is now working on higher power batteries.

Scientists at MIT used the viruses to build both the positively and negatively charged ends of a battery, the cathode and anode, the journal Science reports.

Photovoltaic Panel costs drop towards$1/watt.
  Barron's
With refined silicon at $50/lb. silicon photovoltaics can be sold for $1/Watt and pennies.

A YEAR AGO, REFINED silicon for solar cells cost 450 bucks a kilo on the spot market. You can have it today for closer to 100 and if you wait a month it may be cheaper still. Thanks to the workings of international capitalism, the 90% margins available in last year's market spurred silicon-factory expansions around the planet. But the new supply arrived just as end-market demand for solar panels got eclipsed by faltering government incentives, lower oil prices and the world financial freeze.

-Skip-

As practiced silicon refiners like Hemlock turn on new production, supply may outstrip demand by 50% this year and 75% next year. Latecomers like  LDK Solar (LDK) plan big refineries, although LDK's project just suffered storm damage. In the next five years, producers plan to double capacity from about 100,000 tons this year to 200,000 tons. That will help make solar power as cheap as the fossil-fueled power grid, and it's impossible to overstate how wonderfully that will help stem global warming. But barring a price-fixing conspiracy like some memory chip makers periodically attempt, the solar industry's margins may not be so hot.

Perhaps I will be able to use some of my US$ to buy US made solar panels affordably within a year.
