Japan has launched its first unmanned cargo vessel to the International Space Station carrying food, supplies and scientific equipment for the astronauts there.

The Japan Aerospace Exploration Agency (JAXA) launched the H-IIB rocket, carrying the H-II Transfer Vehicle (HTV) just after 2 a.m. Friday (1 p.m. Thursday ET) from the Tanegashima Space Centre, on an island off Japan's southern coast...
Japan has plans to send one HTV to the station every year until 2015. Japan currently has no vehicles that can take humans into space.

If you listen to inventor Dean Kamen, the biggest health problem facing the world today is not AIDS, obesity or malnutrition. It's a shortage of water...

They've been working on an invention they say can tap into 97 percent of the world's undrinkable water.
It's called the Slingshot, and it's a portable, low energy machine that is designed to purify water in remote villages...

Perhaps you've heard about the Slingshot, which Kamen has been working on for more than 10 years. Over that time it has turned dirty river water, ocean water and even raw sewage into pure drinking water. Kamen says it can turn anything that looks wet, or has water in it, into the "stuff of life."


In summer 2006, Kamen delivered two Slingshots to the small community of Lerida in Honduras. They were used for a month and Kamen says everything ran as planned.

"The machine worked very well down there, taking virtually any water that the people from that village brought to us," he says. "All the water that we got from the machine was absolutely pure water."

ScienceDaily (Sep. 15, 2009) — An international team of researchers, including Monash University biochemists, has discovered evidence at the molecular level in support of one of the key tenets of Darwin's theory of evolution.

Monash University's Professor Trevor Lithgow said the breakthrough, funded by the Australian Research Council and published recently in the journal Proceedings of the Na More..tional Academy of Sciences, provides a blueprint for a general understanding of the evolution of the "machinery" of our cells.

"Our cells, and the cells of all organisms, are composed of molecular machines. These machines are built of component parts, each of which contributes a partial function or structural element to the machine. How such sophisticated, multi-component machines could evolve has been somewhat mysterious, and highly controversial." Professor Lithgow said.

A non-Darwinian explanation, from believers of Intelligent Design, proposed these complex machines to be "irreducibly complex". In other words they are so neatly complex and complete that they couldn't have evolved but rather must have been designed by an intelligent entity.

"Our research shows that these machines although complete and complex, were a result of evolution. Simple 'core' machines were established in the first eukaryotes by drawing on pre-existing proteins that had previously provided distinct, simplistic functions," Professor Lithgow said.

As a model system, the research focused on one specific molecular machine, the TIM complex, which transports proteins into mitochondria. Mitochondria are a compartment of human cells that serve as the energy-producing 'powerhouses'. At a very early stage in evolution, mitochondria were derived from bacteria that lived within the first eukaryotic cells.

"Our cells literally are chimeras of a "host" cell and these intracellular bacteria. Yet bacteria don't have TIM complexes – to understand where the TIM complex came from we simply applied scientific reasoning and looked at a modern-day bacterium akin to the organism that gave rise to mitochondria." Professor Lithgow said.

The group looked at the bacterium Caulobacter crescentus and found bacterial proteins related to the components of the mitochondrial TIM complex. They then showed that these bacterial proteins are not found as part of protein transport machines.

"François Jacob described evolution as a tinkerer, cobbling together proteins of one function to yield more complex machines capable of new functions." Professor Lithgow said.

"Our work describes a perfect example of Jacob's proposition, and shows that Darwin's theory of evolution beautifully explains how molecular machines came to be."

Professor Lithgow was joined by Monash researchers Dr Abigail Clements, Dr Dejan Bursac, Dr Xenia Gatsos, Dr. Andrew Perry, Mr. Srgjan Civciristov and Ms. Nermin Celik together with researchers from the University of Melbourne and Yale University in the US.

This was a house episode not long ago. Only took him 24 minutes to solve it, take that Belgian docs!

It must be really bad to be stuck trying to communicate and going nowhere, at least the upside has to be it cannot happen again since the test for it is now known.
One day Alice came to a fork in the road and saw a Cheshire cat in a tree. "Which road do I take?" she asked. "Where do you want to go?" was his response. "I don't know", Alice answered. "Then", said the cat, "It doesn't matter.”

I thought this article was pretty cool and very interesting. It doesn't surprise me at all that this is a teenager. Many people and many parts of society immensely underestimate teenagers in what they're capable of doing.

PlayStation 3 'hacked' by iPhone cracker

What the article is about:
"A US hacker who gained notoriety for unlocking Apple's iPhone as a teenager has told BBC News that he has now hacked Sony's PlayStation 3 (PS3)."

Perhaps it was thinking of using the camera as a tool too?
