Even in its current fragmented state, the growing, publicly available map--obtained at a cost of $250 million to date, he says--has led scientists to a host of disease genes. It is also letting them probe the genomes of other organisms for DNA that could turn out to be a mother lode for medicine...
...about unmanned space probes going to the stars? Unmanned probes can be much smaller and lighter than manned spaceships. That means the total power required for a probe to reach the stars is much less. But the unmanned probe still needs an engine delivering one megawatt per pound. The problem of cooling the engine remains the same, whether the ship is manned or unmanned, and the conclusion is the same. Unmanned probes are not going to reach the stars within this century...

It avoids the problem of cooling the engine by not having an engine. It is a sailing ship, not a steamship. He calls it Starwisp. It is a fishnet made of very fine wires and weighing less than an ounce. The net acts as a sail and is driven by the pressure of radio waves generated by a huge radio transmitter. The transmitter stays put, with...
