The announcement was made by the Brazillian government based on satellite imagery from the National Institute of Space Research, which shows that during the last 5 months of 2007, 1,250 square miles of rainforest were lost. It is suggested that increases in commodities such as soya have encouraged the illegal deforestation of areas to allow for the cultivation of these crops. This data comes after the success of pio- neering legislation in early 2007, which saw a significant decrease in illegal logging. www.bbc.co.uk/news “1000 Genomes Project” Tuesday 22nd January 2008 saw the launch of the “1000 Genomes Project”, an international project aim- ing to sequence 1000 individuals’ genomes with the hope of guiding researchers to disease-associated regions on the genome and to hasten supplementary follow-on research. Although some observers have questioned whether the project is ambitious enough, the high number of people will allow scientists to look at a greater variation of structural differences than in previous studies and will compare areas of DNA deletion, duplication and rearrangement. www.nature.com/news Curried bird-flu The much-forgotton bird-flu virus is still continuing it’s spread across the world with the virus spread- ing through domestic fowl populations in India. The state of West Bengal in northeast India has seen the H5N1 virus spread into more of the state’s districts, however people are releuctant to hand over the birds for culling. It has been estimated that two million birds need to be destroyed to prevent further spread of the highly pathogenic virus, which can infect most birds and has been known to spread to humans. www.bbc.co.uk/news [2] The Missing Link News and events Events What’s on in and around Bristol this month Shell Wildlife Photographer of the Year 2007 - Winning and commended images from this year’s competi- tion.
