Caterpillars Are Changing into Butterflies Earler
Climate change is making butterflies more violent. They are coming out 10 days earlier than they used to in spring. The change has been caused by a 0.91ºC increase in temperature in Melbourne. All species that interrelate with the Common Brown butterfly (Heteronymph Merope) breed earlier as well.
A group of academics funded by the Australian Research Council has researched this issue. Members of the group studied caterpillars bred at the old and new temperature in the laboratory and noted the changed. Observation of the butterfly in the wild has confirmed that caterpillars are changing into butterflies earlier.
If butterflies are coming out sooner then other insects must doing this as well. This means that crops will have to be planted earlier in to be fertilized by insects. People in cities do not understand the importance of pollination on food crops.

The Hobbit a Small Human on Flores Is Proven
Many people have written off the "hobbit" find as being just a joke, a sad hoax played on society. However, finding tiny "humans" is, apparently, real. Most scientists have accepted it though some still scoff at the whole issue without looking into it.
In 2004 archaeologists in Indonesia found skeletons, not fossils, skeletons of small human-like creatures who lived on the island of Flores as recently as 18,000 years ago. While humans spread around the world, these small "humans" carried on hunting pygmy elephants and other local species in isolation. Flint flakes found in million year old volcanic sediment show hobbit activity there a very long time ago.
The question is - When did the early humans leave Africa? Considering Man left the continent no more than 100,000 years ago why did other excursions of early man end in extinction? At least one group survived long enough to enlighten us about the numerous times humans left Africa. Evidence from bone structure shows that the hobbit descended from an earlier type of human than the small-brained Homo erectus which left two million years ago.
Spending time considering how hobbit came to be on Flores is quite irrelevant. Whether they went by boat, raft or just walked when a land bridge appeared, they got there and thrived.

Fossilised Eggshells Are Ideal for Extracting DNA
Jurassic Park is getting closer to reality. Australian scientists have managed to get DNA from fossilised eggshells of extinct birds. The Team warns though that bringing ancient creatures back to life is a long way off. Particles of fossilised eggshells from Australia, New Zealand and Madagascar were used in the research.
A target species was the Moa bird which lived in New Zealand into the 18th century. Another was the Elephant Bird extinct in Madascar during the 17th century. Older bird were also worked on: the New Zealand Duck, Australian Owl and an Emu which was 19,000 years old. In work on older fossils, results did not come up with usable DNA.
Techniques used were the usual reduction of sample and polymeras amplification. These were very short pieces of DNA obtained from minute samples. Eggshells were found to be even better than bones and hair for storing DNA.

If You Sit Down You Die
Humans are built to stand up all the time. How ridiculous this sounds, but this is what scientists say. You will die younger, get diabetes, and fall victim to cancer if you sit down too much. Doing exercise wont stop it apparently. Even sitting down at any time is damaging. This is "silly science" because though people sit down longer than ever before they also live longer. Statistics prove this.
Scientists say the body only functions "normally" if we are standing. They cease if we sit down. If these body operations work when we are standing what proof is there that they are really necessary? There is no proof. This is just a whim and let's hope it soon passes before people bring cases to court against employers.
There is no more ardent a person against smoking than an ex-smoker. Guess What! The main researcher on all this stuff, Professor Levine, has taken to standing all the time. This bloke is a bit of a nutcase, an obsessive compulsive if there is one - he walks around the room like in the old movies with an almighty long telephone cord. He also invented machines where you can keep walking or cycle while still using a computer. Health and safety has deemed these device too dangerous to use.
Levine wants to change the world like all obsessives. "What you need to do is to create an overall environment of health." Yeah, like those people selling ordinary tea that supposedly makes you lose weight. Beware, the Professor has four large US companies on board to find out how much can be saved in dollars by walking around all the time. You could be next on the test list.
