A new type of rewritable paper that uses water as ink could slash the amount of paper that’s wasted daily, researchers say.
Researchers have created a new kind of generator that uses bacterial spores to harness the untapped power of evaporating water. Scientists from Harvard and Columbia universities have created small, prototype generators by coating a sheet of rubber with a soil bacterium, Bacillus subtilis, that greatly expands and contracts with changes in humidity.

The movies got the facts for this glow right, but why do nuclear reactors glow blue anyway? (more…)
CO2 is an important air pollution emission contributing to climate change. Researchers around the globe are looking at ways to remove CO2 from flue gasses and to store it (sequestering) or to in someway use it.
By tuning gold nanoparticles to just the right size, researchers from Brown University have developed a (more…)
In a time when Australia’s liquid transport fuel supplies are declining and our transport needs are growing, a research partnership between Australia and India could provide a solution to a number of energy concerns and ultimately reduce the reliance of both countries on imported fuels.
The widespread introduction of a clean-burning (more…)
HyperSolar, which develops of a new technology to produce renewable hydrogen using sunlight and any source of water, has announced that its artificial photosynthesis technology is now capable of producing 1.0 volt open circuit voltage for use in direct solar hydrogen production. This achievement represents a voltage increase over the previous 0.2 (more…)
Chinese researchers have developed a method of removing oil from polluted water using tiny barbed spikes that mimic the natural design of a cactus. Writing in the journal Nature Communications, the Beijing-based researchers describe how arrays of tiny copper spikes, similar to the cone-shaped spikes of a type of cactus known as Opuntia microdasys, (more…)
Scientists say they have identified the gene responsible for the yield of oil palm crops, a discovery that could boost the productivity of the world’s top source of vegetable oil and help reduce the size of oil palm plantations in the world’s tropical regions.
Seeds and oils from the plant that produces the loofah sponge could help purify wastewater and prevent the spread of waterborne diseases in the developing world, according to a scientist speaking today at the 17th Annual Green Chemistry & Engineering Conference in Bethesda, Md. The low-cost, biodegradable seeds and substances made from oils of these seeds (more…)
