Bees Swarm in Own Sensor Network

Researchers from the University of Tasmania and Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO) are using sensors to help them better understand swarming bees’ behaviors. They have attached 2.5 mm × 2.5 mm RFID sensors with adhesive to the backs of about 5,000 honey bees in Hobart, Tasmania, Australia, who had been refrigerated briefly to put them to sleep. Researchers claim the sensor is sufficiently light and unobtrusive to affect a bee’s flight. The RFID sensors identify bees to the researchers’ system when the bee passes various checkpoints, thereby letting them track the tagged insects’ movements. The researchers then construct a 3D model so that they can visualize movement patterns. The scientists are investigating several issues about bee health and the environment, including ways to improve agricultural pollination and the effects of agricultural pesticides on honey bees. The researchers aim to further reduce the sensors to 1 mm square so that they can affix them to smaller insects, including mosquitoes and fruit flies. (SlashDot)(Geek)(CSIRO)
 

Researchers Create New Nanoscale Material

An international team of researchers led by scientists from the Commonwealth Scientific and Industrial Research Organisation and RMIT University have developed a new two-dimensional material they say “could revolutionize the electronics market.” The material consists of molybdenum oxide layers in sheets about 11 nanometers thick that are similar to graphite layers. The material’s structural properties, which are also semiconducting, allow electrons to freely flow at ultra-high speeds, which could enable smaller devices to be created that are able to transfer data at high speed. The researchers made nanoscale transistors with the material but say additional research is needed before devices can be made using the material. Other research collaborators included scientists from Monash University, University of California at Los Angeles, and Massachusetts Institute of Technology. The researchers published their work in Advanced Materials. (EurekAlert)(The Commonwealth Scientific and Industrial Research Organisation)
