Robot Bees to Stimulate Pollination
Two scientists from the UK and the US have been jointly awarded £640,000 to build microrobots that simulate the buzzing of bees. Over three years the scientists will work to build tiny robots that can reproduce the buzzes of pollinating bees.

Rethinking Wave Energy Converters Using Variable-Geometry
A major challenge currently facing wave energy technology is the achievement of cost competitiveness. Because they must be designed to be robust enough to withstand large wave loads and unforgiving sea states, about 35%-50% of wave energy converter costs can be attributed to device structural costs alone. Reducing the structural cost and increasing energy capture are two paths toward reducing wave energy's levelized cost of energy, thereby increasing its attractiveness as a major renewable energy source.

First Commercial Scale Offshore Wind Farm in the United States
The US Department of the Interior announced approval of the construction and operation of the Vineyard Wind project — the first large-scale, offshore wind project in the United States. The 800-megawatt project will contribute to the goal of generating 30 gigawatts of energy from offshore wind by 2030.

Flame-Retardant, Insect Repelling Fabric for Soldiers
Using methods to measure heat release capacity and total heat release, as well as a vertical flame test, they found that the modified material performed at least 20% better than the untreated material. They also used a standard insect repellency test with live mosquitoes and found that the efficacy was greater than 98%. Finally, the fabric remained "breathable" after treatment as determined by air permeability studies.

New Green Technology Generates Electricity "Out of Thin Air"
Electrical engineers and microbiologists have created a device they call an 'Air-gen' or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere.

'Phyjama,' a physiological sensing pyjama
Scientists expect that in the future, electronically active garments containing unobtrusive, portable devices for monitoring heart rate and respiratory rhythm during sleep, for example, will prove clinically useful in health care. Now researchers have developed physiological-sensing textiles that can be woven or stitched into sleep garments they have dubbed "phyjamas."
