    with efforts to reduce carbon emissions and to adapt to the effects of climate change Artificial trees could be used in areas of high carbon emissions Photo credit BBC Many climate scientists calculate that the world has only a few decades to reduce emissions before there is so much carbon dioxide in the atmosphere that a dangerous rise in global temperature is inevitable The authors of this report say that geo engineering of the type they propose should be used on a short term basis to buy the world time but in the long term it is vital to reduce emissions They define two types of geo engineering Nem Vaughan of University of East Anglia said The first category attempts to cool the planet by reflecting some of the sunlight away The problem with this is that it just masks the problem The other type of geo engineering is to remove carbon dioxide from the atmosphere and store it Hundreds of options The team studied hundreds of different options but have put forward just three as being practical and feasible using current technology A key factor in choosing the three was that they should be low carbon technologies rather than adding to the problem Dr Fox told BBC News Artificial trees are already at the prototype stage and are very advanced in their design in terms of their automation and in the components that would be used They could within a relatively short duration be moved forward into mass production and deployment The trees would work on the principle of capturing carbon dioxide from the air through a filter The CO2 would then be removed from the filter and stored The report calls for the technology to be developed in conjunction with carbon storage infrastructure Dr Fox said the prototype

    it can also be used in developing countries A research team in California has developed a phone attachment that can test blood or water samples advanced microanalysis previously only possible with expensive bulky hospital equipment Samples could be inserted like memory sticks into the mechanical attachment which reads the slides and provides a diagnosis in plain English no advanced biology classes needed Image Credits Ozcan Research Group Devex Funding came from U S government sources like the National Institutes of Health and the Department of Defense which saw the potential for improving battlefield care telemedicine and public health monitoring in big cities But the product s ability to function in low resource settings makes it applicable to developing countries as well The technology acts like a microscope and diagnostic tool all at once bringing the hospital to the field It uses an algorithm that would allow a front line health worker to quickly test someone s blood for malaria parasites or to get a read on how well a patient s HIV is being controlled with medication People could also manage their health conditions by using the easy to use interface themselves to send test results to a clinic they otherwise couldn t get to The data from these tools can be coded for location and time and copied to a central server providing an accurate and real time picture of a disease outbreak or a water condition for emergency responders or policymakers The attachment brings an army of technologies together basically using all the cool things a cell phone can do like connect wirelessly and do digital imaging and putting them to work together in a new way Dr Aydogan Ozcan who leads the California research team behind the attachment said he got the idea while thinking about how

    in disaster prone countries Speaking in Japan at the Google hosted event Big Tent The Role of Technology in Disaster Preparedness and Relief Ms Wahlström who heads the UN Office for Disaster Risk Reduction UNISDR said Experience shows that early warning messages save lives if people receiving the message know how to act what to do when the emergency strikes There is an opportunity for Google and other providers of information to make themselves part of the chain of education and awareness raising that is necessary to reach all people in exposed and vulnerable regions and to save lives In a number of high risk countries 90 percent of the people have a cell phone and only 10 percent have internet access Innovative partnerships will overcome this gap She pointed out that the internet combined with technologies such as Geographic Information systems makes it possible to better understand hazards and in particular the growing exposure and vulnerability of cities to disasters and risks Easy access to applicable risk assessment and hazard mapping is critical to offer citizens the choice to take decisions on their own safety and how to protect their assets Partnerships with Google and other e providers as well as the insurance industry will speed up the availability of such critical information she said Ms Wahlström said that over the last 30 years Asia has experienced 5 000 major weather related catastrophes more than any other continent over the same period and had also suffered 51 of the world s fatalities from natural catastrophes And the bulk of the record 360 billion economic losses from last year some 80 had occurred in Asia Greater investment in resilient infrastructure was required if the region was to cope with the fact that GDP exposure to flood is now eight times

    of a three year project co funded by the Technology Strategy Board in UK The collar is the result of a joint project between The University of Strathclyde Morrisons Scottish Agricultural College SAC NMR Harbro Well Cow and Embedded Technology Solutions who are developing the technology The equipment involves each cow wearing an intelligent collar that picks up on subtle movements with the same sensor used in Wii gaming and generates a continuous record of their activity patterns Results will then be sent back using a range of wireless technologies like 3G with a full update accessible via a hub or even through a mobile phone It is envisaged that farmers can set up alerts for their phone to receive a text when a cow is in distress coming in to heat or entering labour Wireless technology means that the signal from the cow s collar would be accessible from anywhere so farmers can check on their cattle s status using their phone wherever they are It will provide vital improvements in the important areas of cow illness and streamline the insemination process By accurately sensing the cow s head positions in three dimensions the collar will be able to

    invasive technique may aid conservation efforts to protect the cheetah population in the wild The footprint identification technique FIT has already helped researchers study other big cats and endangered species including bengal tigers and polar bears Now the method has been developed for the first time with cheetahs in a international collaboration involving conservation organisations N a an ku sê sanctuary Wildtrack AfriCat and Chester Zoo Unique print The technique is based on the assumption that every paw print is unique to that cheetah and can be identified similar to a human fingerprint The local San people in Namibia have been able to identify individual animals from their tracks for many years Digital photographs of each cheetah s prints are taken and fed into a computer database Whereas each human fingerprint has a unique pattern of ridges and whorls each cheetah produces a paw print of unique size shape and character Digital photographs of each cheetah s prints are taken and fed into a computer database When a new print in sighted and recorded a bespoke computer program then scans these photographs recording the distances between specific points on the paw print until it finds a match So far researchers have photographed and taken measurements of footprints from wild and captive cheetahs held in N a an ku sê sanctuary in central Namibia Africa and Chester Zoo in the UK They now hope to increase the size of their database to include many more wild cheetahs allowing the cats to be identified in a non invasive way Paw prints from individual animals will enable scientists to understand the movements and interactions of cheetahs plus how many there are in a certain area It is extremely important because you can never catch and collar all cheetah to find out about their
