Treetops
What is a tree, anyway? An assemblage of pipes? A river on
end? "I used to think a branch was a branch," says forest
biologist Kim Steiner. He and his graduate students are finding
it to be no such simple thing.
Redrawing the Family Tree
How close are rabbits and rodents? When did bats evolve
wings? Which is a blackbird's nearest kin, a bobcat or a
boxturtle? And how did those lizards all get to Galapagos? Using
new mitochrondrial-DNA techniques, biologists Linda Maxson and
Blair Hedges and their graduate students are finding answers to
these questions, and more.
The Life of The Pill
The birth control pill "changed the world," says retired
English professor Bernard Asbell, whose "biography" of the drug
shows "how difficult and painful and full of surprises" such
changes can be.
Fine Prints
Among prints by Baskin, Goya, Picasso, Curry, and Kent are
three, by the American Will Barnet, which show abstract
expressionism to be more than chaos and spontaneity, more than
paint thrown at the canvas.
