This means that in evolutionary terms the sexually reproducing populations are the winners on average. "Almost ev......ocysts.

...ompounds exerts a strong control on the extent and efficiency of bioremediation. The use of oxygen (aerobic respiration) yields the most energy to the bacteria and thus results in the most complete and rapid bioremediation. When oxygen is not present, bacteria can use other TEAPs, such as nitrate reduction, i...Study helps identify key step in simple motor learning
...ing didn't change, but the rate of ion flow or the efficiency of glutamate binding were reasonable possibilities. The experiments, however, show that none of these three are present in Purkinje cells during long-term synaptic depression." Now that the only contributor to the lowered response to glutamate is......ngineering. The innovation makes possible the high efficiency conversion of kinetic energy from relatively slow-moving and multidirectional fluid flows into electrical energy. The Gorlov Helical Turbine was also named one of Popular Science's top 100 innovations of 2001. In the pursuit of his lifelong dream of...Aquaporins - the perfect water filters of the cell
...gree of selectivity, aquaporins reach a remarkable efficiency of up to three billion water molecules per second and channel. A membrane patch of 10x10 cm2 with embedded aquaporins could filter 1 liter of water in about 7 seconds. How are these conflicting requirements realized?
