Chemistry - Phones explode because lithium operates by chemical action. Let's not kid ourselves here: The iPad has had battery "explosions" just as much, if not more than Samsung. It is just that Samsung is more outspoken about issues. Apple believes that if it ignores a problem it will go away. I would like to see the real statistics on all phones. Batteries operate by chemical action. What you learned at school was that chemicals are dangerous. The unexpected sometimes happens. Lithium has the capacity to store a lot of energy. This pent-up power is always looking for a way out of its container. Though the incidents of phones catching fire is very low, the mere thought of something exploding in your pocket is frightening. Lithium batteries are notoriously unstable. They have caused fires on aircraft. Thankfully, no one has yet been killed. We do not have any alternative to lithium batteries. They are the most efficient and can be made very small. Consumer

The first singing birds originated in Australia - science. Singing birds originated in Australia. This is true. Just when they moved to other parts of the world is not yet clearly known. Evidence from DNA sequencing and fossils point to this happening approximately 23 million years ago. They first "hopped" from island to island until they reached Indonesia. From there it was easy for them to spread to Asia. The progression to populate the world occurred rapidly, like when humans moved out of Africa.  It took only a few thousand years for the initial "breakout". Birds of song could not leave Australia before 23 million years ago as Indonesia before that time was a small island and there was a huge distance of ocean for the birds to cross to reach other land masses. Half of all bird species are song birds. The only continent where they did not go is Antarctica. This is a mystery because penguins are birds, so the cold barrier is not significant for birds.  Man

Science - Research in Western Australia shows super volcanoes erupted zircon gemstones. The surface of Earth was once covered in diamonds, well a very close imposter anyway. Australian scientists have just found out that a super volcano spewed out zircon crystals all over Australia.  It is a gem stone in many more colors than diamond. Samples from drilling in Western Australia showed particular crystals should have not been there. They were different from naturally occurring ones eroded from rocks. The "strangers" were 2,300km from their volcanic source. The great distance from erupting volcanoes indicates that the volcanic explosions 106 million years ago were much larger than previously thought. Australia must have been a very violent place in the past. Many animals would have died out because of the eruptions. ◆ science  CScience by Ty Buchanan   ◆ Tys Country Amusing Animal Photos Odd Weird Things Articles News Reviews ● Vista Computer Solutions               

Zoology shows men scorn their stepsons, like birds. It is common knowledge that cuckoos "dump" their eggs in other birds' nests to put the responsibility of bringing up cuckoo chicks to strangers. It appeared that birds could not tell the difference between there own offspring and cuckoos. However, this belief has been proved wrong by research on the southern pied babbler of Africa. This bird lives in a group of up to 14 individuals. It has been observed that the dominant male will push out unrelated subordinate males. Females did not show any favor. It is purely a male thing. The prime behavior of the birds is the practice of male birds helping to raise the young of other mating pairs. They obviously remember who is related to whom, particularly in regard to their own young. The males thrown out of groups do not fair well in life generally. Their health suffers. They become skinny and remain that way. Seldom do they become dominant males. There could be a

New technology pins criminals to gun crimes.> It is getting more difficult for criminals to get away with breaking the law. If a gun is used it is now possible to match the gunshot residue to specific bullet cartridges. A criminal will probably keep some unused cartridges at his/her home. The shooter will have residue on this body and the gun anyway. Each batch of bullets has a different chemical makeup. Differing amounts of glass fragments is the main difference. Sensitive High Resolution Ion Microprobe (SHRIMP) and Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) provide extremely detailed analysis of gunshot residue. When a gun is fired, residue to splattered everywhere, on the shooter, the victim and in the wound itself. There is no way of destroying the evidence. Residue can be matched with bullets at a certainty of 99 per cent. It is possible that some innocent people jailed for crimes will be shown to be not guilty with the used of the new techn

Fire caused tuberculosis according to new archaeological theory. Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt. A new premise is that the adoption of fire by early humans caused the emergence of tuberculosis. Apparently, many people crouching around a fire set the ideal conditions for TB to take hold. Just a minute though. Didn't Africans also cook meat on fires and kept near to it for warmth on cold nights? They certainly did. No, this new theory does not hold up. It is assumed that TB is mainly a thing of cold climates.  More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans
