Deadly Viruses Which Kill Cane Toads Identified by Scientists

In the 1930s Australian sugar cane was being destroyed by the grey-backed cane beetle and the French beetle. They are both native to Australia. Scientists looked abroad for a solution. They made the biggest mistake in Australia's history.

Australian cane toad

Cane toads were brought in from Hawaii in 1935. They bred impressively in captivity: this should have been a warning sign. Beetles in Hawaii are not the same as Australian types. Ignoring potential danger 102 young toads were released In Innisfall, Cairns and Gordonvale. Entomologist, Walter Froggatt announced that there would be a disaster - he was right.

Their population exploded across the country. Cane toads did not eat the beetles damaging sugar cane. They devoured native insects, other amphibians and reptiles. Furthermore, creatures that eat them die because they are poisonous.

Fortunately, there has been a breakthrough that could see the end to the dangerous pest. Their DNA has been sequenced. Three viruses have been identified that will kill them. The viruses are specific to cane toads.

As the pest was introduced to new countries they developed new immunities, adapting to local conditions. However, they do not have any resistance to the three viruses. Hopefully when the viruses are ultimately used to control the deadly amphibians native wildlife will recover.

New Species Found in Australia

An endangered animal, Antechinus, has two new members. Well, they have been there all along. A team from Queensland University of Technology discovered the Tasman Peninsula Dusky Antechinus (Antechinus vandycki) in south east Tasmania, and nominated the Mainland Dusky Antechinus   (Antechinus mimetes) . The latter was known to be in New South Wales and Victoria but it is now a species in its own right. The Tasman Antechinus is about 13 cm long with a short tail weighing roughly 90g. It is located in Port Arther, Tasmania. Under threat from clearing of trees it resides in state forest in fragmented groups.  Survival is precarious in the isolated stands. While uncovering new species is rare in developed countries, new ones are being found in Australia all the time. This is due to the low population density of people in inland Australia. Unfortunately, new species when found are usually in small numbers and under threat. Antechinus are not helping themselves...

Albert Einstein's Genius Was Due to His Unusual Brain

Albert Einstein wasn't only a genius her was a very odd human being. His brain shows peculiar differences from the norm; it had many more folds than the average person. This gave the brain a greater surface area. It is like using a larger computer to do calculations. Upon his father's death in 1955, Thomas Einstein gave the pathologist permission to preserve the brain of Albert Einstein. It was photographed then dissected into 2,000 ultra-thin slices. The slices and slides of them were later distributed to researchers. The brain had more neurons and glia cells, well outside of the normal range; pariental lobes were unusual in the pattern of ridges and grooves. Einstein only had a brain of average size. The area controlling the tongue and face was larger, as was the region that involves attention and planning. Overall, Einstein's brain was complex. Many people think in words. He said his thinking was like a physical activity. If selection based on "healthy...

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
