Energy with a grain of saltResearchers have developed a new sodium metal powered fuel cell with up to triple the output for its weight of a lithium-ion battery. The team from  MIT, including Yet-Ming Chiang, think these fuel cells could have enormous potential for electric vehicles — including flight. They say sodium can be electrically produced from salt on a large scale to facilitate this technology. The research was published in the journal Joule.Plants hear their pollinators, and produce sweet nectar in responseA new study has found that plants can respond to the distinctive vibrations of pollinating insects by activating sugar-producing genes to produce rich nectar. In contrast they respond to the sound of nectar-stealing non-pollinators by cutting back on sugar. Francesca Barbero, from the University of Turin in Italy, presented this work at a recent joint meeting of the Acoustical Society of America and 25th International Congress on Acoustics.Penguin poop helps create the cooling clouds over Anta
