Chickens are evolving faster than previously thought, according to new research that challenges ideas of when they were domesticated and may have implications for human migration.
The findings, published in journal Biology Letters, are based on a genetic analysis of a chicken population that can be traced back over 50 generations.
The international team of researchers sequenced 12 mitochondrial genomes – DNA generally thought to be passed down from the mother to their offspring – in a well-known population of White Plymouth Rock chickens.
Previous chicken research – March 2014 – has been used to gauge human events in history, notably that Christopher Columbus beat Polynesians to South America :: Read the full article »»»»

Medical and engineering specialists say they are on the cusp of a breakthrough after successfully transplanting a bionic heart into a sheep.
The bionic heart was designed by Brisbane engineer Dr Daniel Timms in 2001 while he was studying at the Queensland University of Technology.
It contains a spinning disc with small blades on each side that pump blood around the body and lungs, without a traditional pulse.
The bionic heart can last at least 10 years and could help bridge the gap between patients requiring heart transplants and the number of donor hearts available.
The team, made up of Queensland and international researchers, said the device was a significant advance on other designs that were large, prone to wear, or could only pump on the left or right side.
It is expected to be ready for human trials within three years :: Read the full article »»»»

In 1988, beloved British author Roald Dahl wrote some of his most poignant, instructive words. In an open letter, the writer known for his children’s books pierced with dark humour, urged parents to vaccinate their children against measles following the death of his eldest daughters to the same disease.
Olivia Dahl died of measles encephalitis, aged just seven years old. The author went on to dedicate two of his books to her, James and the Giant Peach, and the BFG; “For Olivia: 20th April 1955 — 17th November 1962.” :: Read the full article »»»»

Australian beer drinkers will soon have the option of buying a beer with a much longer shelf life, a new type of malt barley, developed by Adelaide researchers and a Japanese brewer, can curb beers propensity of tasting stale when left on the shelf.
The new barley variety ‘SouthernStar’ is the results of collaboration between the University of Adelaide and Sapporo Breweries. Importantly this new barley is not genetically modified, it’s been produced using conventional – albeit high tech – breeding techniques, utilising data from the recently completed Barley Genome Project .
South Australian farmers are to begin commercial production of the barley this year. Commercial crops grown in 2013 will be harvested in November/December, processed into malt in the first half of 2014 and used for commercial beer production in the later part of 2014 :: Read the full article »»»»
