Monster-wheat grown by Oxford could revolutionise farming
Posted by Shane Hinshaw in categories: energy, food, genetics
A crop spray which can boost farmer’s wheat yields by one fifth, without the need for genetic modification, has been developed by scientists at Oxford University.
Researchers have found a molecule which helps plants make the best use of the sugary fuel that they generate during photosynthesis. And with more fuel, the plants can produce bigger grains.
Other scientists in Britain have developed ways to genetically modify crops to increase yields, and the Department of Environment is currently deciding whether to allow a field trial for GM wheat in Hertfordshire.

The recently discovered element 117 has been officially named “tennessine” in recognition of Tennessee’s contributions to its discovery, including the efforts of the Department of Energy’s Oak Ridge National Laboratory and its Tennessee collaborators at Vanderbilt University and the University of Tennessee.
“The presence of tennessine on the Periodic Table is an affirmation of our state’s standing in the international scientific community, including the facilities ORNL provides to that community as well as the knowledge and expertise of the laboratory’s scientists and technicians,” ORNL Director Thom Mason said.
“The historic discovery of tennessine is emblematic of the contributions Tennessee institutions like Oak Ridge National Laboratory, the University of Tennessee and Vanderbilt University make toward a better world,” Tennessee Gov. Bill Haslam said. “On behalf of all Tennesseans we thank this world body for honoring our state this way.”

MIT’s sensor network tracks your power-hungry appliances
Posted by Bruno Henrique de Souza in categories: electronics, energy
A Marinha dos Estados Unidos fez uma parceria com cientistas do Massachusetts Institute of Technology (MIT) para criar uma rede de sensores barato, portátil que monitora o consumo de energia de cada um dos seus dispositivos domésticos.
O sistema consiste de cinco sensores de tamanho selo-postais colocados acima ou perto de linhas elétricas que entram na casa, que podem identificar cada luminária ou aparelho com base em seu uso de energia. Ele canaliza os dados para um aplicativo em tempo real, permitindo que as pessoas possa ver quando sua geladeira consome para um ciclo de degelo, por exemplo.
“Já existem maneiras de monitorar o uso de energia doméstico, mas elas envolvem a contratação de um eletricista licenciado ou cortando linhas de energia ou tubos caro para anexar, equipamento especializado,” professor de engenharia do MIT e chefe do projeto Stephen Leeb disse em um comunicado de imprensa. “Com o nosso sistema, é possível instalar sensores sem contato usando laços zip ou mesmo velcro, e usar o processamento de sinal para medir o consumo de energia. Também poderia servir como uma maneira de dizer quando o equipamento precisa de manutenção ou substituição.”
