Scientists in Australia Discover 23 New Water Spiders

Australian scientists are discovering new Species every day. It certainly seems this way. Spiders are on the new knowledge table at the moment. Many have been unknowingly in the Queensland museum for a very long time. The new arachnids are in the Dendrolycosa, Dolomedes, Ornodolomedes, Megadolomedes and Mangromedes genera. They are all spiders of the water. New ones in the Ornodolmedes category are the most beautiful of all. Striking patterns and colors abound. The Queensland Museum Network includes existing collections and field trips by scientists recording discoveries. New kinds of arthropods have been found in all Australian states as well as New Caledonia Naming of recent additions have taken a turn as well. They carry the names of celebrities such Mick Fanning, Jack Nicholson and Professor Brian Greene. Soon there will be Blondie, Boy George or perhaps Kiss. Jokes aside, This is an interesting field. Why are there so many spiders that hunt on the surface of water?

Teflon Beats Gecko - Temporarily

Can nature beat science? This is an open question but it will be put to the test. Teflon is a material created by scientists. It does not occur naturally. Will it stand the test and be unique, unfettered by mother nature? Geckos can run along many surfaces, whether vertical or upside-down. Their toes are covered in in rows of keratin ridges called lamellae. They are like very fine hairs that attach to just about anything. Students at the University of Akron's Auburn Science Centre tested the ability of geckos to run along vertical teflon sheets. And yes, they could not cross it! By adding water, however, they ran along it quite happily. Apparently, the presence of moisture is a must for geckos to get around. Any surface that repels water is playground for geckos. An adhesive has been developed that will stick things together underwater based on research done on this interesting little creature. Science by Ty Buchanan http://www.adventure--australia.

Coal and Oil Production Brings Radioactive Sludge to the Surface

It seems it is not only nuclear power that pollutes the earth with radioactive substances. For centuries coal and oil production has brought thousands of tons of polluted material from beneath the planet to the surface. Further processing concentrates it even more.  Apparently the sludge is left lying around and is not isolated from the population. For every barrel of oil pumped up into storage, ten barrels of polluted water is dragged up as well. Uranium and radium occur naturally below ground. In the US plastic pipes used in the production process were given to kindergartens to make playground equipment. The coal and oil industry has known for many years about the problem but has kept very quiet about it. While nuclear power stations are closely monitored, limits are set high for coal and oil which allows producers to pollute at will. Tests for radioactivity on dumps of sludge give readings 700 times higher than clean areas. With new housing estates being built on top of discard

Geckos Cannot "Stick" to Wet Surfaces

Geckos are being studied to find out how they can climb across ceilings without falling off. Their toe pads can support weight equivalent to two people. Like many animals with the capacity to "stick" to things, the main reason they can hold on is the many tiny hairs on their suckers. A hair is further divided into hundreds of gripping setae. The attraction between molecules in the surface and the millions of setae add up to significant sticking power. Water is their enemy. If a surface is wet they fall off. Even on a dry surface, when gecko's feet are soaked in water they cannot hold on. Water tends to stop the superhydrophobic attracted between molecules. This is why geckos lose their wonderful climbing ability. In the wild they would be open to attack from predators in wet conditions. Furthermore, the hope of creating a new adhesive based on geckos is dashed. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.fe

Another Strange Thing on Planet Jupiter

Strange things are happening to the planet Jupiter. A few weeks ago its southern band faded from view. Now there has been a mysterious explosion on its surface. A bright spot was observed for several seconds. Last year's impact created damage on Jupiter that lasted for months. So the latest collision is only minor. It is important news for those who move in "planetary" circles, however. The activity is proven because an observer Anthony Wesley, who discovered last year's impact scar, caught it on video. Another astronomer, Christopher Go, also has video of it. Astronomers have to wait until Jupiter turns on its axis and shows the area again to see if there is lasting damage. Enthusiasts await processing of Anthony Wesley's video to evaluate what actually happened. Christopher Go's Video can be viewed here . http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorat
