Cloned Apples
Grafting -- an ancient way
of cloning plants -- enables
plant scientists to create
new varieties of apples. The
selected genetic traits
allow trees to resist pests
with less pesticides, and to
make better-tasting fruits.

Tulips! Tulips! Tulips!
Of the 1,700 varieties of
tulips, about 80 percent
come from Holland, which
exports more than $700
million's worth of tulips
per year. Tulip bulbs take
up to five years to fully

Plants Under Attack
Plant biologists have
identified the strategy used
by plants to recognize an
attack. When insects ingest
parts of a plant digestion
turns proteins into a
peptide elicitor, which is
secreted back into the plant

HoneyBee Decline
Entomologists are studying
the reasons behind an
enormous bee die off
happening across the
country. They call it Colony
Collapse Disorder, and if
they cannot find a solution
the 80% of fruits and

Soil Chemists Plant Ferns to Soak Up Backyard Poisons
Planting ferns can be a cheaper, greener way to soak up poisons such as arsenic from the soil. Ferns absorb arsenic through their roots and store it in their leaves, which can then be cut off. ... > more -
