Scientists say changes for agriculture could be in store, now that they’ve come up with a detailed
map of how plants react to light. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:
Researchers have been trying for decades to get extensive details on how plants use light to
develop. Scientists at the University of Wisconsin-Madison have come up with a blueprint of
how light tells a plant to germinate, grow and flower.
Plant geneticist Richard Vierstra says corn could be dramatically changed if light-sensitive
molecules called phytocromes can be re-engineered and introduced.
“If we could minimize how phytocromes work …in a cornfield, we could minimize them trying to
compete with each other for light, and so that they would hopefully expend more energy making seeds
rather than making stalks and taller plants which eventually fall over.”
Vierstra says more testing is needed before the photochemical properties of the plant molecules
can be changed. But he says the new map will tell scientists exactly what to do. The research
was published in a recent issue of the journal Nature.

This fall, skyscrapers in New York City are dimming their lights to help migrating birds stay on course as they fly south. The Great Lakes Radio Consortium’s Karen Kelly reports:
The Empire State Building and the Chrysler Building are famous for lighting up the New York City skyline. But if you look closely this fall, you might notice that the lights have been turned down at several famous New York buildings.
It’s part of a voluntary effort led by the Audubon Society. City lights confuse migratory birds, who typically use the moon and stars to navigate. Ornithologist Daniel Klem says thousands of birds die when they run into buildings or fall exhausted onto city streets.
“It’s an astronomical amount of unintended carnage in my view, and anything we can do to prevent it and make people more aware of it will be helpful.”
Klem says skyscrapers in Chicago and Toronto are also turning down their lights this fall to aid the birds on their passage.

Wildlife photographers Carl Sams and Jean Stoick have been taking pictures of Michigan wildlife for more than twenty years. What started as a hobby has become a lucrative business and spawned two best-selling children’s books. But this year, the work has become about more than just taking beautiful pictures. The Great Lakes Radio Consortium’s Charity Nebbe has the story:
(Sound of birds chirping)
It’s early morning, and Carl Sams and his wife and partner, Jean Stoick, have gotten up to take pictures of wildlife in the early morning light.
“Oh, look, we got a deer. Right out there in the water. Is that beautiful. This is incredible. The very doe – I worked here back in 1982 – she crossed this lake, just the lake here, and she was pregnant, and since then I’ve taken over a hundred thousand pictures. Now this doe, she’s actually out eating lily pads right now, and this is typical for deer at this time of year to do that.”
For Carl, taking pictures of wildlife came naturally; he’s always loved spending time outdoors.
“I grew up hunting and fishing, but I sold my guns and bows for a down payment on a lens and now I can shoot a hundred thousand deer and not be arrested, no seasons, no license, and I can be out here all the time. Not many people can make a living at something that they really love. This is a dream.”
When Carl started to make a living from his pictures, he and Jean bought a second camera so she could join him in the field. Most of their pictures are taken near their home at a park in southeast Michigan. And over the past twenty years, Carl and Jean seem to have developed a rapport with the creatures they photograph.

“Okay, ready?”
Jean coaxes a wing-flap out of a female swan as if she was a fashion model.
“Okay, let’s do it.”
(Sound of camera snapping)
STOICK: “Wasn’t she perfect?”
NEBBE: “Exactly on cue.”
STOICK: “Exactly on cue.”
For many years, they sold prints of their work to magazines, calendars, greeting card companies, and on the art show circuit. Then recently, they decided to create a book about white-tailed deer. But as they were selecting their pictures, Jean’s imagination took them in another direction.
“I noticed that we had an awful lot of good images of the deer and birds interacting with a particular snowman that we had built three years earlier. So I mentioned to Carl, I says, ‘You know, why not do a children’s book? It would be a whole lot more fun.'”
That first book became the best-selling children’s book Stranger in the Woods. Their second book, Lost in the Woods, is the story of a fawn alone in the forest. All of the animals it encouters worry that the fawn is lost, but in the end, we learn its mother leaves the baby alone because it has no scent and won’t attract predators. She’s free to forage for food and come back later to take care of her fawn.
The pictures are meant to be beautiful and the book fun to read, but Carl and Jean are hoping the readers will remember what they learn.
“The lost fawn concept is a mistake that people make over and over every spring. They unintentionally rescue fawns that they think have been abandoned, and children are good messengers.”
The couple is working to spread their message with visits to elementary schools and libraries. That fills a lot of their days, but almost every morning and every evening, they can be found doing what they love to do most: taking pictures.
“It’s amazing how graceful she is. I think sometimes she likes to pose. Here she comes again.”

Last year, the first green police station opened in Chicago. It will use 20% less energy, and 30% less water than a typical police station. It’s built of recycled and locally available materials. But it looks pretty much like the other newer police stations you see around the city. Officer Jeffrey Bella who has worked here since it opened, says most people have no idea this is what’s known as a “high performance green building.”
“…and the fact that nobody talks about it and nobody notices it is pretty much a testament to how well it does work.”
This is the first police station in the country to earn a LEED Silver rating from the US green building council. LEED – that’s L-E–E-D- for Leadership in Energy and Environmental Design, is a rating system that awards points for features such as energy conservation, site usage, indoor air quality, light pollution reduction, even proximity to public transit. Levels range from basic certification to silver, gold and platinum.
Last spring, Chicago Mayor Richard Daley announced every new building built by the city, must meet basic LEED standards. Private developers aren’t required to meet LEED standards but they must meet the less stringent city Energy conservation code.
Even that has the development community concerned about higher costs. The Mayor had this to say at the Building and Design conference in February.
“Here in the city of Chicago we have to really educate architects, and engineers and I mean you talk about challenges, that alone – and contractors- because they look at money. Money is the source of their profession, like any other profession. How much money… developers, engineers, archiects, contractors, and subcontractors …so green technology to them means money, it doesn’t mean the technology that maybe you and I think about.”
Even the mayor wouldn’t dispute that most LEED certified construction costs more up front. Washington D.C. economist Greg Kats puts it at roughly 2 percent more. Kats ran a performance study of 40 LEED-certified buildings around the country and found higher initial costs were offset ten fold by a variety of benefits.
“And those benefits pay back very quickly in the form of lower energy costs, lower water costs lower operations and maintenance costs, better building operations. And frankly, people are more happy, they’re more productive, kids’ test scores go up, asthma and allergy problem, which is a real concern for a lot of parents like me, tend to go away in green builings.”
On February 14th, one of the city’ largest real estate firms, LR Developers broke ground on what will be the first LEED-certified luxury high rise in Chicago. LR’s Kerry Dixon says, they built green to differentiate themselves in the luxury condo market, and although they’re not required to be LEED certified, they knew it would please the Mayor. But Dixon says it hasn’t exactly been an important selling point.
“We’re not getting feedback from the marketing and sales staff that yeah, everbody’s interested in it.”
If most condo-buyers are not showing much interest in green buildings, more and more large corporations that want to project greener images are.
“We are one of the nation’s largest energy producers. We are by far the nation’s larger operator of nuclear power plants. Some love us for that, and some are skeptical because of that.”
John Rowe is the CEO and chairman of Exelon. The company is looking to consolidate 3 corporate offices into one location and Rowe was fascinated with the idea of building a new green headquarters.
“But it basically worked out so that it would probably be cheaper. And that if we worked on being green we could probably get just as much credit for using an existing building as a new one.”
That’s because the U.S. Green Building Council also certifies commercial interiors. When it’s finished in 2007 Rowe is confident Exelon’s new corporate headquarters will qualify for LEED’s silver rating. He’s hoping it even makes gold.
For now, the Daley administration has chosen to LEED by example – and hope the private sector follows.
Most of us are using 125-year-old technology to light our homes. 95-percent of the energy used by a light bulb is heat. Only five-percent actually is used to produce light. (Photo courtesy of the National Museum of American History, gift of the Department of Engineering, Princeton University, 1961)
Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient… and the trend in home lighting is moving toward using more energy… not less.

Many of us say we want to be good environmentalists. But we often make choices based on other desires. One of those choices is lighting. Most of us use lights that are very inefficient, and the trend in home lighting is moving toward using more energy, not less. The Great Lakes Radio Consortium’s Lester Graham takes a look at light bulbs and starts at the beginning:
We’re getting a behind the scenes look at a pretty significant historical artifact. Marc Gruether is pulling back a plastic tarpaulin that covers a row of file cabinets.
Gruether: “We are in one of the storage areas in the Henry Ford Museum. And drawer eleven has this light bulb in it which I will very carefully remove. It’s certainly one of the oldest Edison light bulbs that’s in existence. This is one of the lamps that was used in the December 1879 demonstration at Menlo Park.”
Graham: “Now, looking at it, I can see that it’s got that kind of bulbous shape, I can see the filament, I mean, I would recognize this easily as a light bulb.”
Gruether: ““Absolutely. It’s a recognizable light bulb. You’re exactly right. That all looks forward to the kind of lamp forms that became common and that we’d recognize today.”
And that’s not all that’s the same. Just like the first light bulbs, the incandescent bulbs most of us use in our homes today, waste energy. 95% of the energy used is expended in heat. Only five-percent actually makes light. That means everytime you switch on the light – if it’s an incadescent bulb – you’re wasting 95% of the electricity your paying for. In our homes, not much has changed in the last hundred years or so. But in commercial buildings, things have changed a lot.
Commercial builders and industrial architects learned a long time ago that energy efficiency is important. Most of the new office building and factories built today use passive sunlight and high-efficiency lighting that not only saves energy but uses the right spectrum of light to get the best output from their employees.
Moji Navvab teaches about light in architecture at the University of Michigan. He says you can learn a lot about good energy efficient light too. He says with the wide variety of fluorescent, LED, and spot lighting, you can get the right kind of light for whatever you’re doing and use a lot less electricity compared to a house lit only by traditional incandescent bulbs. It’s about using the right light for the right place. Navvab says, really, it’s pretty simple and you can get a lot of information about proper lighting on the Internet.
“If you really are focusing on healthy lighting or you want to save energy, if you go search on the web right away, you can get the information and then you can go to your local stores and they can match it for you.”
But at the local store, most of the time buyers are not very well-informed at all.
Beverly Slack is a salesperson at Kendall Lighting in Okemos, Michigan. She says unless they ask, she doesn’t push energy efficient lighting. And when she does mention fluorescent lighting, which uses about one-fourth the energy that incadescent bulbs use, customers grimace.
“Right. But, they don’t realize the difference in the fluorescent lamps, how they’ve changed, how the different colors have changed in the fluorescents. They’re still thinking of the old standard cool white so, people don’t want them because of that fact.”
Slack says what customers really want is dramatic lighting, and lots of it. They want trendy, recessed lights and track lights that often use extremely hot burning bulbs in a way that’s interesting, but not often very useful.
“They want decorative, decorative, decorative. I mean, it’s amazing. Because I can just see their light bills going sky high.”
Slack says the trend in home lighting in recent years has been just the opposite of commercial lighting. At home, people are using more light, more fixtures, and less energy efficient bulbs. With the trend in new houses being larger, requiring more lights, and homeowners wanting decorative lighting to show off their big new houses, conservation at home is often just being ignored.
It’s no longer about turning off the light when you leave the room, it’s about lighting up the showplace. And as long as the power bill is lower than the mortgage, it’ll probably stay that way.
The invention of electric lights at the end of the 19th Century ended the ancient tyranny of darkness over our lives. Turning on the lights at night has allowed us to make every hour count. But while nighttime lighting has given us unprecedented security and uncountable opportunities, we may be reaching the point where we have too much of a good thing. The Great Lakes Radio Consortium’s Ed Janus reports on two people involved in an international effort to turn the lights down a little and take back the night:
In our urbanized world, we tend to equate bright lights with safety. What we forget, says Great Lakes Radio Consortium commentator Tom Springer, is that too much artificial light blurs the healthy distinction between night and day:
Ultraviolet light, which some scientists say may be the culprit behind
the Great Lake’s epidemic of mutated frogs, is now part of an
investigation into a smaller but equally important part of the
environmental web. Scientists in Duluth are looking into the viruses
that infect bacteria in the Great Lakes, and how increasing amounts of
U-V light might affect that relationship. The Great Lakes Radio
Consortium’s Stephanie Hemphill reports:
