Creating Fragrant Flowers

When was the last time you got a bouquet of flowers that had a

When was the last time you got a bouquet of flowers that had a fragrant smell? While there’s no shortage of beautiful looking flowers for sale, many have little, if any, scent anymore. Ast he Great Lakes Radio Consortium’s Tamar Charney reports, it’s a problem one scientist has gotten a whiff of:


Flowers have lost their smell as flower growers have bred them to be big and brightly colored. Eran Pichersky is a biologist at the University of Michigan. He studies the smell of flowers. Pichersky is focusing his genetics research on whether it’s possible to bioengineer a flower’s scent.


“We actually have some collaboration with biotech companies who are trying to use some of the genes and enzymes we’ve isolated to put them back into plants so that the plant makes more scent, or even new scent that they didn’t make before.”


But it’s not florists who are interested in this work, it’s farmers. Pichersky’s research means it might be possible to alter the smell of flowers in ways that entice bees to visit crops more often, or even attract other insects to do the pollination work. That increase in pollination could mean an increase in crop yields.

Tumors Found on Zooplankton

Scientists are alarmed at the discovery of tumors on tiny animals at
the base of the food chain in one of the Great Lakes. The Great Lakes
Radio Consortium’s Lester Graham reports… no one seems sure what this
will mean to life in the lakes:

Looking for the Perfect Hiding Place

As a child you probably had a hiding place – a nook under the eaves of
your house or a hideout in the backyard. But today’s kids have fewer
chances to play in these places than earlier generations did. As the
Great Lakes Radio Consortium’s Tamar Charney reports there are some
designers at the University of Michigan who are starting to pay
attention to what children want when they play:

‘Greening’ an Old Building

It’s no longer that unusual for builders to incorporate elements of
“green” design into their projects. Often, the buildings are new
construction. But it’s much more challenging to renovate an existing
structure. Now, some colleges and universities are leading the movement
toward green renovation. The Great Lakes Radio Consortium’s Wendy
Nelson reports:

Warmer Winters Drive Songbirds North

Each year, many of us look forward to the return of familiar birds at
the feeder. But a new study has found warmer temperatures are causing
birds like chickadees and larks to find new homes. The Great Lakes Radio
Consortium’s Karen Kelly reports:

Are Today’s Kids Less Active?

The U-S Surgeon General recently declared childhood obesity as aproblem of epidemic proportion in this country. Over the last 30 years,children have been getting heavier, relative to their height. Today,one in five children is at least 20 percent above an optimal weight.The problem may not be so much what kids are eating … as it is what theyare doing.

Environmental Theme Semester

"Environment" is the buzz word at The University of Michigan campus in Ann Arbor this semester. Following a trend among universities nationwide, faculty and students from all different departments here joined together to pay a tribute to planet earth with an Environmental Theme Semester. The Great Lakes Radio Consortium’s Julie Edelson Halpert attended one of the events and has this report:
