Harvard Evolutionary Biologist Asks: Are There Hidden Benefits to Superstitions?
Superstitions have long been a part of human culture. From the extreme ones, like never crossing a black cat, shattering a mirror, or walking under a ladder, to the minor ones, like my necessity to wear my special beanie when I need help writing. There are superstitions for everything. But could superstition be linked to Charles Darwin’s famous theory of natural selection? Could there be a hidden benefit to superstition?
Deaf people feel their way to speech - health - 14 September 2008 - New Scientist
"One of the real mysteries of human language is that people who become deaf as adults remain capable of producing intelligible speech for years in the complete absence of any auditory input," says David Ostry, a neuroscientist at McGill University in Montreal, Canada, who led the new study along with colleague Sazzad Nasir.
Faux Superconductors Pass a Key Milestone -- Cho 2008 (912): 1 -- ScienceNOW
Twenty-two years ago, physicists discovered that certain materials containing copper and oxygen could carry electricity without any resistance at inexplicably high temperatures--well above absolute zero although still far colder than winter in Fargo, North Dakota. Such "high-temperature superconductivity" remains the biggest mystery in the physics of materials, and some scientists are trying to solve it in an unusual way, by simulating the crystals with patterns of laser light and puffs of ultracold atoms. Now, a team in Switzerland has taken a key step in that effort by replicating the basic starting point from which the superconductivity is thought to emerge--a sort of traffic jam in which nothing moves.
Physicists Harness Effects Of Disorder In Magnetic Sensors
University of Chicago scientists have discovered how to make magnetic sensors capable of operating at the high temperatures that ceramic engines in cars and aircraft of the future will require.
Accurate Speedometer For Astronomy: Determining Velocities Of Stars And Other Celestial Bodies
Events on a cosmic scale are often barely discernable on Earth. This explains why astronomers are currently not able to prove directly that the universe is expanding at an ever increasing rate, nor can they search for planets that are roughly the same size as Earth and revolve around a sun-like star.
Seeing Through The Skin: Optic-less Imaging Technology Could Beat Lens-based Imaging Devices
Skin vision is not uncommon in nature. Plants orient themselves to light, and some animals -- such as pit vipers, who use infrared vision, and reptiles, who possess skin sensors -- can “see” without the use of eyes. Skin vision in humans is likely a natural atavistic ability involving light-sensitive cells in our skin connected to neuro-machinery in the body and in the brain, explains Prof. Yaroslavsky.

BBC NEWS : UK : Education : Call for creationism in science
"Some of my comments about the teaching of creationism have been misinterpreted as suggesting that creationism should be taught in science classes. Creationism has no scientific basis. However, when young people ask questions about creationism in science classes, teachers need to be able to explain to them why evolution and the Big Bang are scientific theories but they should also take the time to explain how science works and why creationism has no scientific basis. I have referred to science teachers discussing creationism as a worldview'; this is not the same as lending it any scientific credibility."

Hawking vs Higgs: Heavyweight Bout at CERN's LHC
Professor Hawking's comments are entirely valid from a scientific point of view - the true mission of science is not to be right, but to find out what we don't know. Discovering a lack of Higgs boson will be just as exciting as its presence - solid information about a previously untapped region and further evidence for theories. Just different theories from the ones currently favored.

If they succeed, the group will snatch some of the glory from one of the most prestigious scientific projects undertaken in recent years: the ?3.5bn Large Hadron Collider (LHC), which is to be opened officially in Geneva this week.
Interstellar 'slowball' could have carried seeds of life - space - 04 September 2008 - New Scientist
Now Edward Belbruno and colleagues at Princeton University have shown that planetary systems in young, densely packed star clusters could throw out rocks at a slower pace. They showed that for rocks in certain orbital positions, the gravitational pull of the central star is equal to the pull of other stars in the cluster. This sends the rocks into chaotic orbits that eventually allow them to wander off at about 0.1 kilometres per second - slow enough for other stars to catch them
ET could 'tickle' stars to create galactic internet - space - 08 September 2008 - New Scientist
"But I'm inclined to think that positing the Cepheid scheme is like someone in Marconi's time predicting future radio broadcasters will use giant spark-gap transmitters to reach audiences in large cities," he says. "Better technology means higher efficiency, so using an entire star as the 'carrier' seems unlikely to me."

Cool philosophies : Article : Nature
For the LHC, some of these foundational issues are raised by the role of aesthetics as a guide to physical theory, in particular arguments based on symmetry. At the pragmatic level, symmetry has been an immensely fertile tool, and it underpins the notion of a Higgs mechanism for mass. But there is no rigorous justification for relying on it, and it is possible that the LHC might point the way to a new physics that discards it as a ruling principle.

'Lost World' Beneath Caribbean To Be Explored
"The Cayman Trough may be a 'lost world' that will give us the missing piece in a global puzzle of deep-sea life," says Dr Copley, a lecturer with the University of Southampton’s School of Ocean and Earth Science. Volcanic vents in the Atlantic are home to swarms of blind shrimp and beds of unusual mussels. But similar deep-sea vents in the eastern Pacific are inhabited by bizarre metre-long tubeworms. The researchers hope to find out whether creatures living in the Cayman Trough are related to those in the Pacific or the Atlantic – or completely different to both.
