Sterling D. Allan writes "By injecting a water-ethanol mixture called Aquahol that can be used on most any vehicle, and by producing ethanol from the prolific and multi-use sweet sorghum plant, Tectane's net result is no added emissions to the environment, at a cost savings. This past Wednesday they had a press conference in which they showed a 30-minute short version of a documentary film about their company, being produced by Nicholas Klein, best known for such Hollywood hits as The Million Dollar Hotel starring Mel Gibson and The Venice Project starring Dennis Hopper and Lauren Bacall. A vehicle running on this technology requires only a slight addition to the engine compartment to house the injection apparatus, which is said to increases mileage by between 20 and 40 percent, cutting emissions by 20 to 60 percent, while increasing horse power by 10 to 15 percent, and increasing the lifetime of the engine by 50 percent. It also removes the need for the catalytic converter, as well as environmentally destructive chemical additives to the fuel like MBTE. The modification enables almost all cars to run on any fuel, including low (75) octane gasoline, which is cheaper, requiring less refinement. The second part of the equation is in the ethanol production method that they promote, using sweet sorghum. The plant can grow without pesticides or expensive fertilizers, grows prolifically, with little water, producing two crops per season; and the entire plant can be used, not just a portion. The stalk fibers can be used as a substitute for wood composites, eliminating the need for deforestation for buildings. The grainy top can be used for animal feed. The pulp can be used for paper production, and has been by the paper company, Cascade, since 2003. The leftover biomass can be used in energy generation plants, being an ideal fuel since it is neither too dry nor too wet."

Nanorust Used To Purify Water 99

eldavojohn writes "How do you remove arsenic from water? Well, a research team has discovered that adding and removing nanorust works well. From the article, 'The team added nanoscale iron oxide to contaminated water, where it clumped together with the arsenic. They then magnetized the nanoparticles with an electromagnet and pulled them out. "We only needed a surprisingly weak magnetic field," says Colvin. "In fact, we could pull then out with just a hand-held magnet, making this a very practical method.' Big news for developing nations that are plagued with non-potable drinking water."

Not quite: it's more interesting than that. The Nature Biotechnology paper referenced in TFA goes into more detail.

A simple version: the anthrax bacterium makes a particular protein complex - the anthrax toxin - that disrupts cell membranes. This toxin has seven-fold symmetry, meaning that it is made up of seven identical subunits. There are various peptides that bind to each subunit and inhibit the anthrax toxin, thereby protecting cells.

What this group has done is to make liposomes (fat globules, not antibodies) with different concentrations of these peptides on the surface. When the density of inhibitory peptides on the liposomes roughly matches the density of target sites (one on each of the seven subunits) on the anthrax toxin, the inhibition is much more efficient. (This means you need much less of the peptide to protect cells.)

This general idea - of putting lots of inhibitory agents on one particle or compound - has been done before. The big advance here is that this is an easy way control the number & density of the inhibitors. Pretty slick.
