one — on Saturday night. And a Boston law forbids taking a bath unless one has
been so ordered by a physician.

Can fish feel pain? Russell, Elma, New York, USA
Perhaps so. Recent findings from Scotland indicate some can.
Investigators (from Roslin Institute and the University of Edinburgh led by
biologist
Lynne Sneddon now at Liverpool University) used a variety of approaches, but the clincher was behavior.
After the team injected simulated bee venom (a chemical extract) into the lips of rainbow trout, the
trout indicated pain by
- rocking with pain, much as mammals do
- rubbing their lips on the gravel floor of the tank and on tank walls
- taking three times longer than the control fish to resume eating after
being 'stung' by the 'bees.'

How many rings does Saturn have? Megan, Aurora,
Nebraska, USA
The Voyager spacecraft took pictures of Saturn's Rings in 1980 and 1981,
which showed thousands of thin rings — some less than a half-mile across
(600 m), others up to maybe five miles (10 km) across. The rings group
into four main bands, separated by gaps, and three fainter, narrower ones.
Nobody knows the exact ring count.
