"Aerogel, one of the world’s lightest solids, can withstand a direct blast of 1kg of dynamite and protect against heat from a blowtorch at more than 1,300C.
Scientists are working to discover new applications for the substance, ranging from the next generation of tennis rackets to super-insulated space suits for a manned mission to Mars.
It is expected to rank alongside wonder products from previous generations such as Bakelite in the 1930s, carbon fibre in the 1980s and silicone in the 1990s. Mercouri Kanatzidis, a chemistry professor at Northwestern University in Evanston, Illinois, said: “It is an amazing material. It has the lowest density of any product known to man, yet at the same time it can do so much. I can see aerogel being used for everything from filtering polluted water to insulating against extreme temperatures and even for jewellery.”
Aerogel is nicknamed ...Write Comment (0 Comments) |

A few weeks ago I posted an article on how it was time to start your herbs for the season. Normally at the beginning of March this is the case, however if you live in the Northeast, this year seems to be a bit different.
As I look out my window in my New York home, I can't help but feel a little depressed that it is April 12th and it is snowing outside. With all of this talk about global warming, I find my large picture window in my kitchen packed with pots with all of my started herbs. I swear that my basil plant is about one day from shouting "I want to go outside!"
I have had to attach a light over the large window sill so some of the herbs have enough light so they avoid reaching and stalk out too much. I have all my planters sit at the ready to be filled with dirt and put into the sun.
I can't imagine what the local garden shops are going through right now. By now I am...Write Comment (0 Comments) |

The Wind Tunnel Foot Bridge is a new covered bridge for the 21st century; a design proposal for a new kind of wind activated footbridge made of steel and aluminum. As the wind blows, the five wind turbine wheels turn at different speeds around the people who are walking through to reach the other side. Link Write Comment (0 Comments) |

NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years.
"These observations give the strongest evidence to date that water still flows occasionally on the surface of Mars," said Michael Meyer, lead scientist for NASA's Mars Exploration Program, Washington.
Liquid water, as opposed to the water ice and water vapor known to exist at Mars, is considered necessary for life. The new findings heighten intrigue about the potential for microbial life on Mars. The Mars Orbiter Camera on NASA's Mars Global Surveyor provided the new evidence of the deposits in images taken in 2004 and 2005.
"The shapes of these deposits are what you would expect to see if the material were carried by flowing water," said Michael Malin of Malin Space Science Systems, San Diego. "They have fin...Write Comment (0 Comments) |

The American Psychological Association has established a style that it uses in all of the books and journals that it publishes. When editors or teachers ask you to write in the “APA Style,” they do not mean writing style. They are referring to the editorial style that many of the social and behavioral sciences have adopted to present written material in the field. Continue reading on APA Writing Style at Article Land.

Portugal has started building their largest solar power facility yet!
"The 58m euro (£40m) plant near Serpa, 200km (125 miles) south of Lisbon, will produce enough electricity for 8,000 homes when it starts next January.
The 11-megawatt solar power plant, to be made up of 52,000 photovoltaic modules, will cover a 60-hectare (150-acre) southern-facing hillside."Write Comment (0 Comments) |

Scientist at Ghent University in Belgium and University of Queensland in Australia are working on a prototype device that generates electricity from the solid waste that we humans produce every day.
The process works by harnessing the energy that waste-eating bacteria make and turning it into electricity.
Not surprisingly, the researchers are hoping to use the technology to power water treatment plants, but they say a domestic power plant is also possible in the futureWrite Comment (0 Comments) |

Even among astronauts, Neil Armstrong gets special respect - he was, after all, the first man to walk on the moon.
On Tuesday, the Apollo 11 astronaut got a piece of the moon rock he brought back to Earth. "I get to keep it myself only so long as I speak today. So I'm going to be talking longer than usual," Armstrong, 75, joked at a ceremony in which NASA presented him with the rock.
The rock - about 2 grams of medium light grey, fine-grained basalt encased in clear plastic - was part of NASA's Ambassadors of Exploration award. It was created to commemorate the 35th anniversary of the July 20, 1969, moon walk by Armstrong and fellow astronaut Buzz Aldrin.
NASA has also designated the astronauts of the Mercury, Gemini and Apollo programs as Ambassadors of Exploration.
Armstrong accepted the award at the Cincinnati Museum Center, where it will be on permanent display. About...Write Comment (0 Comments) |

Dinner and dancing are hallmarks of any successful courtship. The same holds true of chickens. A good rooster knows what a fickle hen wants - some pecking at the ground, a little singing, some prancing about.
Over the last decade, however, researchers have noticed that, in certain lines of roosters, courtship is becoming a lost art.
It seems the quest for a perfect breast has turned some roosters into sexually aggressive sociopaths.
"What we were seeing was roosters attacking hens in some of the meat-type birds," says Suzanne Millman, a professor in the veterinary college at the University of Guelph, who examined the phenomenon for her PhD.
"They were jumping right into mating without doing all the stuff to make the hens interested in them."
Millman says the problem is specific to what are called broiler breeders. They are the birds used to breed chickens for eating.

A meteorite believed to have come from an asteroid belt between Mars and Jupiter sold for $93,000 US Tuesday at an auction of rare space sculptures.
The 160-kilogram chunk of iron, thousands of years old and discovered in the Campo del Cielo crater field in Argentina, was one of 10 meteorites that went for astronomic prices at a Bonhams' New York natural history auction.
The pristine meteorite, known as Valley of the Sky, was purchased by a private collector in the United States who bid by phone and plans to display it as a work of art, said Thomas Lindgren, acting director of the natural history division for the Bonhams auction house.
"This is art, not from man, but from outer space," Lindgren said. The auction house had expected it to sell for between $40,000 and $50,000.
"He was absolutely ecstatic," Lindgren said of the buyer. "There was no way he was going to walk ...Write Comment (0 Comments) |

From space, Earth looks blue and green. But put your nose to the ground, and you'll probably see just brown.
Where does the brown ground come from? Green plants, a new study reveals.
As plants wilt and die, their leaves and limbs drop off, bringing carbon that they've stored for a living to the soil. Tiny microbes in the earth rip the dead plants apart with specialized enzymes, which break the chemical bonds in the plant material, cutting meals into the perfect size for microbes.
The hungry microbes process a large amount of the carbon in the soil, even incorporating some of the element into their own cells.
As busy as they are, microbes can't get all the work done.
"They're not quite a hundred percent efficient," said Steven Allison, an ecologist at the University of California, Irvine. "There's carbon that doesn't get eaten by a microbe and there's carbon in t...Write Comment (0 Comments) |
