Scientists meeting at the third International Barcode of Life conference in Mexico City last week have agreed on a region of DNA that will be used to identify plants by genus in a new system of codification.
Although genetic “barcoding” of animals, which allows scientists to identify animals from a small section of their DNA, is already well-established, the system has until now not worked for plant species.

With the recent drop in costs for photovoltaics (PV) and the effect of dust and haze on solar-thermal technology(the technology originally planned) has caused a rethink in supplying energy to Masdar. The utilities management company has decided to use 50% photovoltaics and 50% solar thermal due to costs. Although photovoltaics produce 20% less energy than solar thermal they will cost 33% less to install. The use of solar power will cost more than 2.5 times the cost per kwh than the current method generating energy via natural gas.

London Development Agency reports
The London Development Agency (LDA) has congratulated a London company that has been recognised for its innovative and environmentally-friendly approach to construction.
The company was recognised for its potential contribution to the engineering and construction industries at the London Technology Fund (LTF) Competition awards ceremony held on Wednesday night at the Royal Bank of Scotland’s head office. Sarah Ebanja, Deputy Chief Executive at the LDA presented the Environment Award to Novacem, a start-up company developing carbon-negative cement.
Novacem, a spin-out from Imperial College London, has developed a groundbreaking type of cement, which has the potential to transform the cement industry from being a significant emitter of CO2 to being an absorber of CO2. Novacem estimates that for every tonne of ordinary Portland cement replaced by Novacem cement, around 0.75 tonne of CO2 could be captured and stored indefinitely in construction products.

Own an iPhone or an iPod touch? Well I just came across a new app from Autodesk Sketchbook Mobile(link to Autodeskpage) that enables you to sketch ideas or even full sketches.The app is based on the Autodesk Sketchbook Pro application (RRP$100USD).
Looking at the this app I thought that could have many applications for built environment professionals including sketching ideas for clients instantly, making notes on a plan on site, make notes on site photos for use later during site analysis, or mark and note site photos during construction inspections and many other applications. The application includes 3-6 layers, 25 different brushes and pens, zooming up to 2500%.
The Autodesk Sketchbook Mobile(link to App store) is available from the iTunes app store for $2.99. or you can download the Free Trial version Autodesk Sketchbook MobileX (link to App store)
