The reproductive spores of many species of fungi have evolved remarkably drag-minimizing shapes, according to new research by mycologists and applied mathematicians at Harvard University. In many cases, the scientists report in the Proceedings of the National Academy of Sciences, the drag experienced by these fungal spores is within one percent of the absolute minimum [...]

Attention in biofuel development has shifted recently from the soil to the sea, and specifically to marine algae. An emerging algal biofuel consortium now sees algae as a “green bullet” — science and society’s best hope for a clean bioenergy source that will help loosen broad dependence on fossil fuel, counteract climate warming, and power [...]

Entirely new protein structures are very rarely found to drive known biochemical processes. But molecular biologists have just succeeded in finding an example. They studied the protein ASST, present in pathogenic E. coli bacteria, which cause urinary tract infections. In addition to an entirely new structure, the researchers found a transfer mechanism similar to ping-pong, [...]
