A whirlwind recap of the links that piled up in my blogfodder folder.

Medical doctors at Massachusetts General Hospital have discovered that hydrogen sulfide gas can cause the metabolic processes of mammalian cells to drop drastically, thus approximating a state of suspended animation. By breathing a low concentration of the gas the heart rates of experimental animals plummeted rapidly without a corresponding drop in blood pressure or the need for refrigeration; moreover, the state appears to be reversible. This means that the organism requires less oxygen in the depressed state, which means that cells remain viable much longer. The surgical applications should be obvious.

The Internet Storm Center reported not too long ago …

Self-assembling three-dimensional crystals of DNA.

Scientists working in the burgeoning field of nanotechnology at Brookhaven National Laboratory have announced another breakthrough in molecular technology: They figured out how to use DNA to guide the construction of crystals on the molecular scale. It goes a little something like this: Because the nucleotides that link together to create DNA (adenine, thiamine, guanine, and cytosine) have regions with different patterns of electrical charges, individual molecules are attracted to one another and can stick together, rather like complimentary pieces of velcro. Moreover, each nucleotide has more than one region which can create a bond - this is how other parts …
