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.

Beetle Controls Purple Loosestife

A European plant called purple loosestrife is increasingly making
itself at home near lakes, wetlands, and meadows throughout the Great
Lakes region. That’s bad news for native plants that are pushed out by
the aggressive newcomer. But help could be on the way. The Great
Lakes Radio Consortium’s Tracy Samilton reports on a program to
introduce a loosestrife-munching beetle:

Mayflies Make a Comeback

People have long considered the burrowing mayfly a pest. And 40 years
ago, they were glad when the clouds of bugs virtually disappeared from
the Great Lakes. But the mayfly is making a comeback. And as the Great
Lakes Radio Consortium’s Karen Kelly reports, scientists say it’s a sign
of a healthier water system:

Mutant Ladybugs Control Pests

It’s nothing new to get predators to get rid of pests. The colorfuland cute ladybug, for example, loves to devour aphids, mites andmealybugs and is used by many people instead of pesticides. But workingwith these flying predators presents some problems. Now, one researchermay have a solution. The Great Lakes Radio Consortium’s Wendy Nelsonreports:

El Nino Creates Ladybug Explosion

El Nino has been blamed for several things this year…And now there’s one more—an explosion of ladybugs. The Great Lakes Radio Consortium’s Beverly Amsler explains:
