Jurassic Piranha Fossil is Earliest Flesh-Cutting Fish

The fossil of a piranha-like jurassic fish shows a flesh-slicing eating ability. The specimen was the first bony fish to have this capacity. Teeth were much like the South American piranha. However, the ancient creature lived in the ocean not in freshwater. People eat the piranha and say it tastes like other fish.

Did Australian Aboriginals Plan to Reach the Continent?

Aborigines were the first out of Africa and first into Asia. Aboriginal Australians left Africa earlier that East Asians and Europeans according to analysis of DNA from a 90-year-old hair sample.

DNA From Mucus Shows the Sex of Whales

Genetics: Scientists work on whales instead of cattle.
Work on cattle genetics has shown the way to determine the sex of whales using a sample taken from blow holes. Specimens are composed of water and mucous membrane material.  They are collected from the sea by people in dingies, canoes and kayaks. The process involves scooping with a six-metre long carbon-fibre pole.
Getting samples of whale mucus
A team of researchers has enjoyed the chance to get away from working with cattle. They have also done a genetic study of koalas. Improving cattle and meat are their priorities, however.  A few hundred samples are to be taken.  This compares to a half a million already collected from cattle.

While blow hole samples are used for whales, hair is taken from cattle. Researchers have identified favourable traits for cattle from DNA. The real problem is getting these into cattle. Farmers are the ones who breed animals, not researchers. It is no surprise to find the more direct work on whales a welcome change.

New Chinese Theme Park for Australia?

A theme park is to be built at Warnervale in New South Wales. It is not your usual holiday inspired park like Marine World or Disney World. The name of the new entertainment precinct is not yet known, but it will be devoted solely to things Chinese. Buddhist

It is aimed more at Chinese tourists than Australians. A panda paradise, thanksgiving temple and treasure ship are expected to draw the customers. A massive half a billion dollars is dedicated to the project.

The rather odd name of "Chappypie China Time" is being put forward as the preferred choice by Chinese developers. This choice will not go down well with Australians. It is awkward and doesn't translate well into Australian culture.

It will based on "old" China, not the present totalitarian state. Things such as a copy of the Forbidden City, thousand-hand Guanyin and dragon boats will be the main theme.  Developers say it will rival Sydney Harbour Bridge and the Opera House. However, these are thing quintessentially Australia. How can a Chinese project be marketed as an Australian icon?

The Wyong Shire Council insisted that the park must have rides to make it relevant to Australian customers. Disney has also said that legal action will follow if the word "Disney" is in the park's name. The move by the Chinese consortium comes as a bit of a shock to Disney which says there is no local market there for such a huge investment.

Such a project could be a ruse to build a thanksgiving temple. This will be the first thing constructed. It could also be the last. Local people would not want such as large temple built near to them. Councillors should be wary of the "easy out" clause in the contract.

Australian Refugee Policy is Seen as Ruthless by the World

Lieutenant-General Angus Campbell, military commander of Australia's People-smuggling operation believes that "Australia is seen as reasonable and generous in its treatment of refugees."  How stupid and out of touch can you be.  The world knows that Australia couldn't care less about the welfare of refugees.

Don't get me wrong here:  I was the first person in Australia to suggest sending those seeking asylum home, on this very blog.  However, I said economic migrants should be flown home, not turned around in Indonesian waters and send into imminent danger in a small (provided) orange boat.

Agreements should have been reached with the countries of origin of the disenchanted people to safely transport them home.  Australia is in the top three nations resettling refugees, but we are falling fast from this position because our actions are draconian.  They are ruthlessly too effective.  No other country has taken such harsh measures.

The real problem is that Australia is charging and sentencing people smugglers when such behavior is not illegal internationally.  It is not a crime.  First the Lieutenant General fully supported the government then he promptly distanced himself by saying, "I think the question of appropriateness is something both for the government of the day, the parliament and the people, it's not for me to comment,"  It certainly isn't for you to comment, at all!

New Jellyfish in Coffs Harbour

It seems humans know just about everything. This is a myth really. A new species of jellyfish has be seen in Coffs Harbour, NSW. It seems the marine creature has been there for a long time.

The mystery "object" is a box jellyfish that appears to be totally harmless. It is unlike the Irujandji and is smaller than the dangerous Chironex flecker box jellyfish. Fishermen have been seeing the new jellyfish for sometime but authorities took no notice. A game crew took photos of the animal last week.

Finally "professionals" acted and arrangements are being made to catch some specimens. Fish of all kinds are moving south as the temperature of the ocean increases due to climate change. It is believed the visiting jellyfish come from more northern climes. Usually jellyfish do not move south because they can be harmed by rougher seas. They prefer the warm, calmer tropics.
