Columbus (OH) - Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial ...

Age-old recipe: Instant porridge has been part of human diet for more than 8000 years, researchers have found (Source: iStockphoto) Related Stories Breakfast 8000 years ago wasn't that much different from what we enjoy today, according to a study that describes the world's oldest known cooked cereal. Dating from between 5920 to 5730 BC, the ancient cereal consisted of parboiled bulgur wheat that Early Neolithic Bulgarians could refresh in minutes with hot water. "People boiled the grain, dried it, removed the bran and ground it into coarse particles," lead author Soultana-Maria Valamoti says. "In this form, the cereal grain can be stored throughout the year and ...

Glowing cat may shed light on disease-fighting strategy by John Pope Monday October 20, 2008, 10:40 AM Everyone knows that cats can see in the dark, but that wasn't good enough for some New Orleans scientists. They produced Mr. Green Genes, a cat that glows in the dark and is destined to be more than just a novelty for Halloween parties. He's a nearly 6-month-old orange tabby but, under ultraviolet light, his eyes, gums and tongue glow a vivid lime green, the result of a genetic experiment at the Audubon Center for Research of Endangered Species. Mr. Green Genes is the first fluorescent cat in the United States, said Betsy Dresser, the center's director. The researchers ...

Fighter Jets Ordered to Shoot Down UFO By Noah Shachtman EmailOctober 20, 2008 | 12:26:00 PMCategories: Bizarro
Mcchordf86reduce_2 At the height of the Cold War -- and hysteria about alien invasions -- two U.S. fighter planes were "scrambled and ordered to shoot down a UFO over the English countryside," Reuters reports. The incident is one of thousands of UFO-related files, declassified and released by the British government today.
In one document, F-86 pilot Milton Torres describes his encounter with a huge, erratically-moving object in May, 1957.
"The order came to fire a salvo of rockets at the UFO. The authentication was valid and I selected 24 rockets.

Here's a whopper of a story if it ends up being true: Autoweek is reporting General Motors has placed the next-generation C7 Corvette program on indefinite hold due to the company's shaky financial situation. Sources within GM are saying the program has been shelved for now with no specific timetable for release. This is not to say the 'Vette is dead, only that GM's management has no clearly defined direction for the car. With the pressure from 2020 CAFE requirements and with coffers running dry, there are other more important programs to tend to. Autoweek goes on to look into their crystal ball and imagine a time when the C7 will actually bow as early as 2014 — yikes. ...

Chimps: Not Human, But Are They People? By Brandon Keim October 14, 2008 As a population of West African chimpanzees dwindles to critically endangered levels, scientists are calling for a definition of personhood that includes our close evolutionary cousins. Just two decades ago, the Ivory Coast boasted a 10,000-strong chimpanzee population, accounting for half of the world's population. According to a new survey, that number has fallen to just a few thousand. News of such a decline, published today in Current Biology, would be saddening in any species. But should we feel more concern for the chimpanzees than for another animal — as much concern, perhaps, as we might feel for ...

Contact: A'ndrea Elyse Messer aem1@psu.edu 814-865-9481 Penn State Deep magma matters in volcanic eruption cycle Although the Soufriere Hills volcano on Montserrat exhibits cycles of eruption and quiet, an international team of researchers found that magma is continuously supplied from deep in the crust but that a valve acts below a shallower magma chamber, releasing lava to the surface periodically. "Continuous records of surface deformation are available for only a few volcanoes," says Derek Elsworth, professor of energy and geo-environmental engineering, Penn State. "The Soufriere Hills volcano has been erupting since 1995 and provides a peek into the processes ...

Iowa State researchers developing wireless soil sensors to improve farming AMES, Iowa -- Ratnesh Kumar keeps his prototype soil sensors buried in a box under his desk. He hopes that one day farmers will be burying the devices under their crops. Kumar is leading an Iowa State University research team that's developing transceivers and sensors designed to collect and send data about soil moisture within a field. Eventually the researchers are hoping the sensors will also collect data about soil temperature and nutrient content. A major goal is to build small sensors (the prototypes are about 2 inches wide, 4 inches long and less than an inch thick) that can do their work entirely ...

7 June 2006 The largest Atlantic Halibut, Hippoglossus hippoglossus, ever recorded was caught and landed by professional net fisherman Rolf Larsen (62 years old), at Stamsund, Lofoten, Norway (within the Arctic Circle but with seas warmed by the Gulf Stream) This massive fish weighed 282 kg (that's ruffly 621.7035793617 lbs, folks!) and would have probably weighed 290 kg when first caught. The difference was because of the loss of blood after capture. Its total length was 262 cm. The fish was sold for display. *AND ANOTHER* A 39.25 stone (550 lb) Halibut caught by Arthur D. Campbell (d. 2006) at the East Horns Iceland on 18th May 1963. Fish landed in Aberdeen, Scotland by the Ben ...

An entrepreneur claims to have invented a machine that turns a cheap bottle of plonk into a vintage-tasting wine in a matter of minutes. The machine recreates the effects of decades of ageing by colliding alcohol molecules in the bottle Photo: CATERS Inventor Casey Jones says the £350 gadget uses ultrasound technology to recreate the effects of decades of ageing by colliding alcohol molecules inside the bottle. The Ultrasonic Wine Ager, which looks like an ordinary ice bucket, takes 30 minutes to work and has already been given the thumbs up by an English winemaker. Mr Jones, 53, said: "This machine can take your run-of-the-mill £3.99 bottle of plonk and turn it into ...
Persian wind catcher inspires US Inc.

A modern wind-powered machine inspired by Persian wind catchers is to warranty a high quality wind electricity generating system. Windation Energy Systems, a California-based company, says that their wind appliance resembles more or less like the modern heating and cooling equipment. Mark Sheikhrezai, CEO and founder of Windation, explains that there is a 8-by-8-foot frame around a 10-foot-high cylinder. Wind blows in the top, directed to the bottom and turns a turbine to make up to 5 kilowatts of electricity. A single unit wouldn't be capable of generating enough power for an entire office building but could develop a significant portion. Sheikhrezai, who was born in Iran, got the ...

Nobel physics prize goes to 2 Japanese, 1 American By MALCOLM RITTER, AP Science Writer Two Japanese scientists and an American won the 2008 Nobel Prize in physics on Tuesday for theoretical advances that help explain the behavior of the smallest particles of matter. The American, Yoichiro Nambu, 87, of the University of Chicago, won half the $1.4 million prize for mathematical work he did nearly a half-century ago. "I had almost given up" on getting the Nobel, Nambu said. Makoto Kobayashi and Toshihide Maskawa of Japan shared the other half for a 1972 theory that forecast the later discovery of a new family of subatomic particles. The insights of the three scientists ...

No Virgina, evolution isn't ending Category: Evolution Posted on: October 7, 2008 3:20 AM, by Razib I've already the covered Steven-Jones-evolution-is-ending story at my other weblog. I notice that John Wilkins has also objected to Jones' exaggerations. When I initially read the quotes from Jones in The Times I was alarmed, but wondered if his position was being taken out of context or misinterpreted. I emailed a prominent evolutionary biologist who I suspected would know Jones well enough to clarify this issue. My correspondent responded that Jones really does believe this, and he finds Jones' ideas as ludicrous as I do (adding for good measure he doesn't get the ...

Genes may explain racial disparities in asthma Mon Oct 6, 2008 1:57pm EDT NEW YORK (Reuters Health) - Asthma patients who are black tend to have more severe disease than asthma patients who are white, leading to more asthma control problems, higher rates of emergency department visits, and overall worse quality of life. These findings point to genetic differences that lead to poor responses to drug therapy as the source of these racial disparities. Based data obtained from The Epidemiology and Natural History of Asthma: Outcomes and Treatment Regimens (TENOR) study, Dr. Tmirah Haselkorn and colleagues undertook an in-depth analysis in an attempt to explain the differences between black ...

Asian mom, white dad: C-section more likely ZOSIA BIELSKI From Wednesday's Globe and Mail October 1, 2008 at 9:26 AM EDT Researchers have found that Asian women pregnant with white men's babies are more likely to deliver by cesarean section, and are now recommending that doctors factor in both a mother and father's race when they consider the risk of birth complications. Thirty-three per cent of couples consisting of an Asian mother and white father had C-sections. By comparison, 23 per cent of couples with a white mother and Asian father had cesareans. The researchers speculate this is because Asian women tend to be "smaller people" than Caucasians, and that ...

Spotless Sun: Blankest Year of the Space Age Sept. 30, 2008: Astronomers who count sunspots have announced that 2008 is now the "blankest year" of the Space Age. As of Sept. 27, 2008, the sun had been blank, i.e., had no visible sunspots, on 200 days of the year. To find a year with more blank suns, you have to go back to 1954, three years before the launch of Sputnik, when the sun was blank 241 times. "Sunspot counts are at a 50-year low," says solar physicist David Hathaway of the NASA Marshall Space Flight Center. "We're experiencing a deep minimum of the solar cycle." A spotless day looks like this: The image, taken by the Solar and Heliospheric ...

Love is blind for fish in murky waters 18:03 01 October 2008 NewScientist.com news service Ewen Callaway Some female fish have eyes for their man only. Colourful African cichlids have evolved into new species because females are partially blind to others. But even as that discovery is made, the species are under threat because the polluted waters they live in are causing them to interbreed. Among several closely related species of cichlids living in Lake Victoria, males come in either red or blue. Brighter males tend to get the girls, but new research suggests that both sexes have evolved to preferentially see only one colour, creating new species of fish in the process. "Reds ...

Heroic ants pay the ultimate price to safeguard nest 11:15 29 September 2008 NewScientist.com news service Andy Coghlan Ants in Brazil have provided the first example of insects sacrificing themselves to pre-empt a threat. At sunset, the ants seal up the entrance to their nest, but in doing so a few remain outside to kick sand over the entrance hole until it becomes invisible. These ants then die due to the cold, or get blown away in the wind. There are many examples in nature of insects sacrificing themselves when a colony or nest is under attack, such as when bees use their stings to defend the hive and die in the process. But the door-sealing activities of these 2-millimetre ants ...

Invisibility cloaks could take sting out of tsunamis 12:31 29 September 2008 NewScientist.com news service Colin Barras Invisibility cloaks that are able to steer light around two dimensional objects have become reality in the last few years. But the first real-world application of the theories that made them possible could be in hiding vulnerable coastlines and offshore platforms from destructive tsunamis. The first working invisibility cloak, built in 2006, guided microwaves around a small, flat copper ring as if it wasn't there. By October 2007, a device repeated the trick for harder-to-handle visible light, and some progress is reported on the yet more complex task of making ...

Lucky for some: Science of superstition Black cats, broken mirrors; superstitions may seem silly, but, asks Sanjida O'Connell, could they be the secret of our survival? Barack Obama played basketball the morning of his victory in the Iowa primary, and continued the tradition in every subsequent primary. The athlete Kelly Holmes laid her kit out in an exact order the night before a race. Superstitious habits are common; who doesn't cross their fingers, start at the sight of a black cat, touch wood and avoid walking under ladders? Superstitions seem irrational, but they pervade human life. The evolutionary biologist Dr Kevin Foster, from Harvard University, and Dr Hanna Kokko, ...

Genetics of Coat Colour in Dogs May Help Explain Human Stress and Weight A discovery about the genetics of coat colour in dogs could help explain why humans come in different weights and vary in our abilities to cope with stress, a team led by researchers from the Stanford University School of Medicine reports. The study, published in the Nov. 2 issue of Science, answers a longtime mystery: What determines coat color in dogs? While researchers have known since the 1900s that most mammals share the same genetic mechanism to determine coat color, by the 1950s they began to suspect that dogs were different. Now after swabbing the inner cheeks of hundreds of dogs and analyzing the DNA in the ...
