Robotic bees
Researchers from Northeastern University are working to develop robotic bees. Steps have been taken to develop both the hardware for miniature flying robots (e.g. microchips, fuels cells and transmitters), and the software to simultaneously manage large numbers of robotic bees. … Continue reading
Data mining: a tool for social initiatives
The 2012 US presidential campaign provided a platform for the development of new voter interaction tools. The Obama campaign personnel developed two projects, Narwhal and Dreamcatcher, to capitalise on interaction with voters. The technologies mobilised the voting base and used … Continue reading
All-carbon solar cell built by Stanford scientists
Stanford University scientists have built the first ever carbon-only solar cell which may be a promising lower cost (and high performance) alternative to current photovoltaic energy devices. Existing solar cells often rely on multi-step processing and rare metals such as … Continue reading
An international approach for data centres
Approximately 30 million kW of electricity is used by data centres across the world, around the same as 30 nuclear power plants. The power demand in data centres (per rack) is growing very quickly for the UK and other developed … Continue reading
News: River eco-systems could be improved with new Cranfield research
A new remote-controlled ‘boat’ being developed at Cranfield University for the Environment Agency could assist in the recovery of fish populations in UK rivers, by improving migration routes and access to vital food and breeding grounds. The surveying device, or … Continue reading
Commercialisation of synthetic fuel made from air and water
Air Fuel Synthesis, an English company, has begun producing gasoline (petrol) from air and water. The company’s process combines carbon dioxide and hydrogen to create synthetic gasoline. Electrolysis is used to separate water into hydrogen and oxygen and carbon capture … Continue reading
Nanoparticles – a new study suggests they could stunt crop growth
A new study on nano-zinc oxide and nano-cerium oxide, two common nano particles, suggests that they can accumulate in crops such as soybeans and may stunt soil- fertilising bacteria. These findings may have food supply implications. Zinc oxide (ZnO) and … Continue reading
