MikShapi writes "Skin cells can now be turned into something resembling stem cells. A genetic modification to four genes using a viral vector reverses differentiating, making the cells revert to a stem-cell state, capable for becoming any other cell in the body. The researchers are calling them 'iPS cells' or 'induced pluripotent stem cells.' In their experiments, iPS cells in the lab turned into nerve cells, heart muscle, and other tissues. The research was published in Cell and Nature by teams from the universities of Kyoto and Wisconsin. The article notes that if the new method proves successful, 'we can disconnect the whole stem cell debate from the culture war, from battles over embryo politics and abortion rights.' And, should this technique be adopted, stem cells will henceforth be abundant, easier and cheaper to come by for research and therapeutic purposes."Read more of this storyat Slashdot.
Kyle Spector writes "A global futurist research firm convened an expert panel to forecast the major areas and potential advances in technology innovation through the year 2025.

hereisnowhy writes "A giant fossilized claw discovered in Germany belonged to an ancient sea scorpion that was much bigger than the average man, an international team of geologists and archaeologists reported Tuesday. In a report in the Royal Society's journal Biology Letters, the team said the claw indicates that sea scorpion Jaekelopterus rhenania was almost 2.5 meters long, making it the largest arthropod — an animal with a segmented body, jointed limbs and a hard exoskeleton — ever found. In the report, the authors said the scorpion exceeds previous size records for arthropods by almost half a meter."Read more of this storyat Slashdot.
An anonymous reader noted that "The Arecibo Observatory funding was slashed. Cut to $8 million from $10.5 million, which will decrease the amount of time that the telescope is operational. "A quarter of its staff was laid off last year," and Arecibo, which is located in Puerto Rico, could possibly be completely closed in four years, according to the "National Science Foundation (NSF), which pays for the operation of the telescope." This comes after "a review panel for the foundation's astronomy division two years ago" suggested cutting Arecibo's financing by 25 percent as a way to pay for new facilities. There has been "[a]n outcry" in response to the "decision, particularly from planetary scientists" who argued that the panel "overlooked Arecibo's role in cataloging potential dangers from asteroids." The Times notes that in Arecibo's favor is the fact that it "may be much cheaper to keep...open" than dismantle, which "could cost hundreds of millions of dollars."" I've been considering a vacation to PR for a few years, and seeing this thing is on my list of awesome things to try to see. Guess I should hurry ;)Read more of this storyat Slashdot.
coondoggie writes to tell us that NASA has announced a new low-cost satellite that could be ideal for those who wish to get into space quickly and (relatively) inexpensively. "The Fast, Affordable, Science and Technology SATellite (FASTSAT) is 39.5 inches in diameter — not much larger than an exercise ball. It is hexagonally shaped and clocks in at a little less than 200 Lbs. It can carry a payload up to 110 Lbs. [...] NASA said FASTSAT is just the right size for earth observing missions, space science missions, and technology demonstrations. 'We think we can do whole missions for less than $10 million instead of the traditional $100s of millions, and that includes the launch vehicle, the satellite, and the widget you want to test,' said Marshall Space Flight Center's Edward 'Sandy' Montgomery in a release."Read more of this storyat Slashdot.

Smivs writes "Scientists have concluded that moons like the Earth's are actually quite rare. Only 5-10% of planetary systems are likely to contain moons formed by planetary collisions. 'By the time the Earth's moon formed, when the Sun was 30 million years old, the planet formation process in our Solar System should have been approaching its end. In the latest study, Dr Gorlova's team looked at the heat signature of stars using the infrared. This allows astronomers to predict how much of that heat comes from the star itself and how much is re-emitted by dusty material encircling it.'"Read more of this storyat Slashdot.

Today, Putin has just approved construction of Vostochny between 2010 and 2018 which will be positioned in the far east of Russia to complement the Plesetsk Cosmodrome in the northern part of the country. This is not bad news for Kazakhstan as the director of the Russian Federal Space Agency has announced they plan to operate this facility alongside Baikonur."Read more of this storyat Slashdot.

realwx writes "New Zealand scientists have found a bacterium, named 'Methylokorus infernorum,' that eats a key global warming chemical. Found in a hot spring, the bug lives off of methane emissions from geothermically active areas. A scientist quoted in the article stated that a cubic meter of liquid containing the bacterium would consume about 11kg of methane each year. 'But Dr Stott cautioned that such an application was probably some years into the future. He said it was unlikely the micro-organism, which prefers acidic conditions of about 60C, could ever be added to sheep or cows' food to stop the animals releasing methane.'"Read more of this storyat Slashdot.
Roland Piquepaille writes "Wind power is one of the world's fastest growing electric energy sources, but as wind is intermittent, a single wind farm cannot deliver a steady amount of energy. This is why scientists at Stanford University want to connect wind farms to develop a cheaper and more reliable power source. Interconnecting wind farms with a transmission grid should reduce the power swings caused by wind variability and provide a somewhat constant and reliable electric power (or 'baseload' power) provided by other power plants."Read more of this storyat Slashdot.
KentuckyFC writes "Bird flu gets all the headlines but ordinary flu kills several orders of magnitude more people each year and represents a significant threat to our society. The frightening thing about ordinary flu is how little we understand about how it spreads. According to a report at the physics arXiv blog, researchers trying to model this process say they still don't know some basic probabilities associated with infection (pdf, abstract). For instance, given that the disease has manifested itself clinically in an individual, what are the chances of that person dying? And if a virus can be caught from a number of different host species (as it might eventually be with bird flu) what is the probability of transmission?"Read more of this storyat Slashdot.
An anonymous reader writes "A team led by the University of Colorado at Boulder and the University of Milan has discovered some unexpected forms of liquid crystals of ultrashort DNA molecules immersed in water, providing a new scenario for a key step in the emergence of life on Earth. CU-Boulder physics Professor Noel Clark said the team found that surprisingly short segments of DNA, life's molecular carrier of genetic information, could assemble into several distinct liquid crystal phases that "self-orient" parallel to one another and stack into columns when placed in a water solution. Life is widely believed to have emerged as segments of DNA- or RNA-like molecules in a prebiotic "soup" solution of ancient organic molecules.Read more of this storyat Slashdot.
