DNA provides window into early Aboriginal history

Scientists have used hair to locate where distinct Aboriginal groups lived in Australia up to 50,000 years ago.

The genetic study could help reconnect indigenous families with ancestral communities, according to the University of Adelaide-led study.
It shows the first Australians spread rapidly before largely spending continuous time in distinct areas.
The research is an important step in learning more about ancestry prior to European settlement, the authors said.
It again confirmed that Aboriginal Australians descended from a single population that arrived 50,000 years ago from New Guinea, when it was joined to Australia.

Genetic map

The research, published in the journal Nature, analysed 111 hair samples taken by anthropologists from across Australia in the early 20th Century.
The DNA allowed researchers to trace maternal ancestry through unique genetic material.
"What we've found is that we can see right the way back to the first colonisation of Australia by Aboriginal people," said lead author Prof Alan Cooper.-read more

Neanderthals 'self-medicated' for pain

Neanderthals dosed themselves with painkillers and possibly penicillin, according to a study of their teeth.

One sick Neanderthal chewed the bark of the poplar tree, which contains a chemical related to aspirin.
He may also have been using penicillin, long before antibiotics were developed.
The evidence comes from ancient DNA found in the dental tartar of Neanderthals living about 40,000 years ago in central Europe.
Microbes and food stuck to the teeth of the ancient hominins gives scientists a window into the past.
By sequencing DNA preserved in dental tartar, international researchers have found out new details of the diet, lifestyle and health of our closest extinct relatives.
"Their behaviour and their diet looks a lot more sophisticated and a lot more like us in-read more

Hundreds of passengers are stranded at Heathrow when British Airways cancels flight to San Francisco due to a MOUSE being spotted on the plane Read more: http://www.dailymail.co.uk/news/article-4271666/Flight-cancelled-MOUSE-spotted-plane.html#ixzz4aTNW2vxK F

A British Airways flight to the US has been cancelled after a mouse was seen running through the plane.

The flight to San Francisco was due to take off from London Heathrow at 10.40am this morning but was stopped at the very last minute.

Passengers were taken off the plane and transferred onto another aircraft which took off some hours later.

The woolly mammoth died out after losing its warm coat… and its sex life

The woolly mammoth was not so furry when it died out… growing a weird, semi transparent satin coat.

New research suggests the mammoth also had a poor sense of smell – and sex life – just before being wiped out after suffering a “genomic meltdown”.Experts say this can happen when a once thriving species reaches the brink of extinction, as small populations develop mutations caused by in breeding.

The last mammoth disappeared from the planet almost 4,000 years ago, but the groundbreaking findings have implications for animal conservation today.

They also shed fresh light on the theory of evolution, and serves as a warning for those interested in bringing the woolly mammoth back to life, known scientifically as “de-extinction.”

There are at least three teams trying to rebuild the whole mammoth genome – which could one day become a template to recreate actual mammoths.-READ MORE

Distinctive British bird is under threat of EXTINCTION as they lose habitats

The curlew with its distinctive call and long curved bill is under threat as experts warn the species faces extinction world-wide.

In Britain they are a regular site on coastal marshes and mud-flats easily identifiable by their long legs and curved bill.

But ornithologists reports that although curlew species occur on all continents except Antarctica some species may already have become extinct.

Nicola Crockford, policy officer for the RSPB, said: "The Eurasian curlew is an iconic species - its appearance in spring is announced by one of nature's most evocative calls.-READ MORE
