Suppose you could repair tissue damaged by a heart attack by magically
turning other cells into heart muscle, so the organ could pump
effectively again. Scientists aren't quite ready to do that. But they
are reporting early success with animal studies. Associated Press,

A researcher has successfully cultured brain cells taken from the desert
locust to delve deeper into the workings of the mammalian neurosystem.
Easier to work with than human neurons, the use of these insect neurons
allow the team to observe the neurons form a network, providing enormous
benefits to researchers. American Friends of Tel Aviv University, 11/29.

Say "laboratory animal" and most people will think of mice. A few
sophisticates might nominate the fruit fly. But rare will be the person
who suggests the roundworm. The Economist, 11/29. URL:

The European Union's REACH (Registration, Evaluation, Authorization and
Restriction of Chemicals) legislation is the world's most extensive
attempt at improving the safe use of chemicals. Nature has investigated
whether the European chemicals industry will meet the deadline and what
will happen if it does not. Nature, 11/30. URL:
