of bacteria which can pass electrons to an anode, the negative electrode of a fuel cell. The electrons flow from the anode through a wire, producing a current, to a cathode, the positive electrode of a fuel cell, where they combine with hydrogen ion...
Protein abundant in human tumors confers resistance to anticancer drugs
...owever, the details of the biology underlying drug action
and why some cancers are drug resistant are not well understood. A research team led by Dr. Donald Kufe from the Dana-Farber Cancer Institute in Boston, Massachusetts examined the role of a protein called MUC1 in drug resistance in cancer cells. The ...

of AA in stabilizing memory still is unknown, this molecule has already been implicated in memory formation in chickens and rodents. The current genetic findings from flies therefore suggest that the radish/phospholipase A2-dependent form of memory s...

would also remove carbon dioxide from the atmosphere and "store" the remnants in the added soil, the impact would be "trivial" compared to expectations from boosted tree growth, Schlesinger said. Based on available evidence from the Duke experiment, ...
