High fructose corn syrup and sugar sweeten lots of food.

They’re in sweet stuff like soda-pop, but they’re also added to pasta sauce, gravy, bread, and other foods that don’t seem sweet.

Scientists are debating whether high fructose corn syrup is worse than sugar when it comes to making us fat.

But Shawn Allee reports high fructose corn syrup is losing ground before that science is finished.

Let’s face it, most of us did not know high fructose corn syrup sweetened so much food.

We have no excuse now: the food industry sponsors ads like this one.

“sugar cube face forward.”

Here, a policeman lines up suspects.

There’s an ear of corn, a sugar cube, and a plastic honey-bear bottle.

The cop turns to the victim of the crime.

“… Do you see the one responsible for you gaining weight?”

“I’ve seen that high fructose corn syrup guy on the news. maybe it was him.”

“you mean you’re making all this up without any proof?”

At this point … the policeman lets the corn sweetener go.

The sugar cube and the honey bear bumble out, too.

“maybe it’s a sugar-cube. No, no, no. the honey bear!”

There’s a reason we’re seeing ads like this.

One market research survey showed more than half of consumers had “some concern” about corn syrup.

Some feel like the victim in that ad – they have this vague fear corn syrup’s worse for your waistline than sugar.

And they know scientists really are looking at this question.

“this particular study has stirred up extraordinary interest … much more than we expected.”

Dr. Bart Hoebel is from Princeton University.

A while ago his research team fed rats watered-down sugar.

Those rats didn’t get fat, but recently his team looked at what happened when rats drank watered-down corn syrup.

“The ones drinking fructose gained more weight … even though they’re taking in fewer calories there was something special or different about the high fructose corn syrup in that group.”

Hoebel says there’re several studies like his moving through the scientific pipeline.

They all look at whether eating high fructose corn syrup is worse than eating sugar … but he worries the public’s missing a big point.

Nearly all scientists agree we get too many calories from both corn syrup and sugar.

But … market research shows people miss the caveats and mixed results behind the science.

They’ve made up their minds.

“They’re looking for an ingredient that they know and sugar is a more recognizable ingredient.”

That’s Dr. Helen Jensen.

She studies food economics at Iowa State University.

She says some food companies don’t care if customers have the science right or wrong.

“so from the manufacturer’s point of view, they’re looking to make more product mixes that offer consumers the choice of having a sugar-based product.”

That’s why you’re seeing products that say sweetened with real sugar.

For example, the Pepsi company is pitching a sugar-version of Mountain-Dew while its regular version is still sweetened with corn syrup.

Other companies are switching, too.

Jensen says this is a big change.

“Tariffs raise the price of sugar. And subsidies for corn used to make corn syrup cheap.”

today it’s a little different. While sugar is still more expensive, it’s not as expensive as it used to be.

So, Jensen says if consumers are pushing a company to switch from corn syrup to sugar, the company just might pay more for ingredients to keep more customers.

But Jensen has a word of caution for people who hope sugar wins the battle over our sweet tooths.

She says countries like Australia sweeten a lot of food, too.

But they use almost no corn syrup … they use sugar, and Australians have gotten more and more obese, just like we have in the U-S.

The Skinny on High Fructose Corn Syrup

We know eating too much sweet stuff puts on the pounds. A new study suggests the kind of sweet stuff matters too. Shawn Allee reports:

We know eating too much sweet stuff puts on the pounds.

Shawn Allee reports a new study suggests the kind of sweet stuff matters, too.

Food companies mostly sweeten things with table sugar, called sucrose, or they use high fructose corn syrup.
Dr. Bart Hoebel is at Princeton University.

A while back, his team fed rats regular food and let them drink watered-down sucrose to see if they’d put on fat.
They didn’t.

But, recently he let rats eat the same food, but drink a solution of high-fructose corn syrup.

“The ones with the high-fructose corn syrup became significantly fatter.

Corn sweetener companies dismiss the study since it involves rats, not people.”

Hoebel says rat studies point out where we should do human studies later.

“So we want to find out if the kind of sugar matters as the food producers are putting sugar in more and more things.”

More research on corn syrup is in the pipeline, including work on animals and people.

Mice Morphing at Warp Speed

Evolution takes place over long stretches of time: millennia and epochs. But some new research shows that animals might be changing much
faster than nearly anyone thought. Gabriel Spitzer has more on those
changes, and how they seem to be linked to humans:

Tall Trees Park is a little patch of green in Glenview, Illinois – a
northern suburb of Chicago. About a hundred years ago, a lot of this area
looked a lot like this. It was mostly farms and pasture and forest. And now
of course it’s a lot of strip malls and subdivisions and stuff. And the
population has grown seventyfold. The climate has changed, too. It’s
gotten a little warmer, a little wetter.

And all this has made life a lot different for the northern white-footed
mice who live here. It’s actually not just made life different for the
mice, it’s changed the mice themselves.

That gets back to a guy named Oliver Pergams. He’s an ecologist, and in
the mid-90s, he was looking at deer mice who live on the Channel Islands
off the coast of California. And he was taking these mice and comparing
them to museum samples of the same kind of mice from the same place, but
decades earlier.

“And I found something kind of strange – that the older specimens were
larger than the newer specimens, so they shrunk in size over a period of
about 30 or 40 years.”

That got him wondering if those relatively quick changes are happening in
other places. So years later, now on the faculty at the University of
Illinois at Chicago, he gathered up some of those White Footed Mice from
the Chicago suburbs. And he went to the Field Museum of Natural History…

(sound of a cabinet opening)
… where they have a hundred years of dead mouse specimens stored in
white metal cabinets.

“Here we have trays and trays of the northern white-footed mouse.”

With a tiny caliper, he’d measure their skulls, their feet, the distance
from their eyes to their noses.

“So this one here was collected by Aikley in 1903.”

And he compared mice from before and after 1950.

“Here are some skulls, this one was collected in 1989.”

Lo and behold, these mice had grown: by more than 10% on some measures.

This phenomenon goes way beyond Chicago. Pergams measured more than 1,300
rodents from four different continents – Alaskan lemmings, Mexican
gophers, Filipino rats. Some of them got bigger, some smaller. But across
the world, most of the animals have changed over time spans thought to be
mere evolutionary eyeblinks.

The next step is to figure out why.

“You can’t get in a time machine and go back and look to see what
actually happened. So the next best thing is to see if there’s
associations or correlations with big factors.”

He found the variations correlate with changes in climate and human
population density. The exact reasons aren’t clear – more people might
mean more yummy trash for the mice to eat, for example. That’s going to
take more research to figure out, and these critters might be overdue for
some extra attention.

“One of the questions is, well, why didn’t anybody notice this before?
And I think the answer is, they haven’t looked.”

Larry Heaney curates the Field Museum’s mammal collection. He says
Pergams’s research opens up new questions about how animals respond to
changes driven by humans.

“The implication is, these animals are changing very, very rapidly. So in
a sense, it’s good: they can change. But the other side of the coin is,
they’re having to change.”

Now, the question is, is this happening in other species, too? What about
birds or bugs or plants?

“There’s been this default attitude that if you go to one place and you
capture or you observe animals or plants, that essentially there’s going
to be the same animals or plants 50 years or 100 years later. I don’t
think that’s possible to assume at all. We have to include the fact of
this change in all of our decisions, from ecology to evolutionary biology
to conservation.”

Pergams’s findings show that even the most common creatures have more to
teach us – when we ask the right kinds of questions.

Dog Doo a Delicacy for Rats

Nature is a big buffet table. One thing eats another – that eats another –
and so on. That’s a fundamental concept of ecology called the food chain.
One city is giving everyone a lesson about a dog’s place in the food chain.

Nature is a big buffet table. One thing eats another – that eats
another – and so on. That’s a fundamental concept of ecology called
the food chain. One city is giving everyone a lesson about a dog’s place
in the food chain. And as Shawn Allee explains, it’s a lesson some would
rather not hear.


Katherine Raz takes up the leash of a slow-moving, black dog. But she’s not
walking her dog through snow. Raz is a professional dog walker.


Allee: “This is one quiet dog.”


“Oh yeah, she’s pretty mellow. Velvet. Velvet. See, she doesn’t even respond
when I call her.”


Velvet is in no hurry to walk, but Raz has got to hustle. She walks dozens of
dogs each week. And business is growing.


“Since I’ve been up here, we’ve had to hire three other people to cover all the
people who’ve called for walks.”


Some residents say all the new dogs are making a big mess. Velvet stops to
prove the point.


“I’ll use the produce bags to capture this. This is a fine specimen here. As
far as picking up the feces, I always thought it was just a cosmetic thing.”


But a sign informed her otherwise.


“I was walking a dog late at night and I was actually stopping to read the sign
because I was so bored. And it’s like, please, pick up the dog droppings because
rats use them as a primary source of food. I was like, Oh, God that’s horrible.
That just gives an image that’s not pretty.”


Indeed, Chicago’s putting dog owners on notice. The city put up that sign
Raz found. It came from the Chicago’s Department of Streets and Sanitation.


Fliers at City Hall say the same thing.


I read one of those fliers to Jose Cruz, Chicago’s rat control Czar.


“They prefer fresh food but will eat many things, such as pet food, dog
droppings, quote – a rat favorite.”


Allee: How do we know that’s the case, that dog droppings are a rat favorite?


“Because we’ve actually come across locations that we don’t see that there’s
not a huge problem with people not containing their garbage.”


The problem is that people are not picking up after their dogs.


Allee: And if I live in a neighborhood where people aren’t picking up after their dogs?
Am I in trouble for a rat problem in the future?


“No, you’re not. Just because there’re lots of dogs, doesn’t mean you’re going to
have a rodent problem.”


Cruz says it all turns on whether people actually clean up. But will enough dog
owners really do that?


Katherine Raz isn’t sure.


“See, there’s a dropping someone didn’t pick up.”


Allee: How often do you see that?


“Oh, all the time.”


Maybe the owners don’t read the signs. Or…maybe they just don’t buy the
dog – feces – rat connection.


I don’t either.


So, one night I meet up with an urban ecologist. Joel Brown is with the
University of Illinois at Chicago university.


Allee: Where are we?


“Right now we’re on the grounds of the UIC greenhouse. It’s a small green patch
that’s bordered by the Kennedy, a large parking garage, and one of the science and
engineering buildings.”


But it’s enough space to let nature run its course. Brown points to a darkened
patch of weeds and trees. He swears I just missed a rabbit.


“You can hear a cottontail running right through the underbrush right here.”


There’s more to observe, though. A falcon dines on pigeons that land here.
Dogs eat the rabbits. And there’s a raccoon that snatches food from the student
parking lot.


Brown says all of these have found a niche in Chicago.


“So what you see is a very dynamic process. Nature is not an art gallery; it works
around us and works in response to us.”


But could rats really take advantage of that neighborhood’s growing dog population?


Brown says, maybe. But perhaps not in the way the city claims.


“It is more likely that a single French fry, or a dog biscuit, pet food left
outside, a
sandwich left on a park bench … all of the incidental bits of food that we leave
behind
without even thinking about it. Those are much more likely to be feeding and breeding
the rat population than dog poop.”


He says it’s a minor link, but the city makes a good point nonetheless.


“That’s the part that, to me, is exciting. The fact that they’re even thinking about
these connections, shows they’re thinking smart.”


Ultimately, signs with dire warnings can’t control dogs’ impact on the neighborhood.
Brown says the behavior that matters most comes from a peculiar animal.


That’s the one that walks on two legs, has a big brain, and can recognize its own
connections to
the natural world.

New research shows that animals exposed to a chemical found in plastics are more likely
to develop prostate cancer later in life. Scientists say their research is the first to find
such a link. The GLRC’s Mark Brush has more:


The chemical is known as bisphenol A. And it’s used to make the hard plastic found in
everything from microwave cookware to baby bottles to CDs – just to name a few. The
researchers say that rats exposed to this chemical in their mother’s womb are more likely
to develop prostate cancer as adults. They say the rats were exposed to low doses of the
chemical, similar to the levels found in humans.


Gail Prins headed up the study published in the journal Cancer Research.


“I want to take a lot of caution. I’m not saying that I have evidence that this is causing
human cancers, I’m just saying it’s part of the body of evidence that these type of
chemicals and exposures may be a contributing factor.”


Prins says it’s difficult for people to avoid these chemicals because they’re in products
we use everyday. But she says plastic containers tend to release more chemicals when
they are heated.

Wily Coyotes in the City

  • Coyotes have started to lose their wildlife habitat, and now they are adapting to cities and suburbs. (Photo courtesy of Michigan Department of Natural Resources)

As wildlife habitat is displaced by subdivisions, some animals are adapting to their new surroundings. That’s created new food for some kinds of predators, such as coyotes. The GLRC’s Lester Graham reports on how their range is expanding:

As wildlife habitat is displaced by subdivisions, some animals are
adapting to their new surroundings. That’s created new food for some
kinds of predators, such as coyotes. The GLRC’s Lester Graham reports
on how their range is expanding:


Wile E. Coyote hasn’t always had the greatest life out in the wild.


(Sound of Roadrunner)


So… some coyotes are moving into the city, and why not? There’s a
smorgasbord for coyotes in the city.


(Sounds of ducks and geese)


We’re in Lincoln Park in downtown Chicago. Coyotes are occasionally
sighted around here. Rob Curtis has seen one in his neighborhood a few
miles north of here, but the wildlife photographer had a close encounter
with a coyote here in Lincoln Park.


“Well, I knew that it was living there because people had seen it before,
but I hadn’t seen it. And then, I was trying to photograph a rare bird that
was in front of the fence there and I was camouflaged and it came up
right in front on the other side of the fence without it noticing me, and
then it just walked on.”


The coyotes eat just about anything they can get a hold of: rats, young
geese, squirrels… and… sometimes pets. In the Chicago suburb,
Arlington Heights, coyotes have been a problem.


Police Sergeant Nick Pecora says sometimes coyotes are pretty brazen.


“In the last 18 months Arlington Heights has lost one Yorkshire Terrier,
taken off the patio in the owners presence, and in one case the dog had an
electronic collar on and when the coyote took it, it received a shock and
dropped the animal and ran away.”


Pecora says some Arlington Heights residents haven’t been too keen on
what some see as an intruding predator.


“Coyotes are indigenous to the area and – maybe it’s the perception that
this is a large animal and the bunnies, the skunks, the squirrels, that’s
what Arlington Heights is used to, and a 35-pound animal walking
through your yard, I think they’re perceived as the big, bad wolf, if you
will.”


And… although there hasn’t been a documented case of a coyote
attacking a human… some worry that they might.


Not too far away researchers are putting radio collars on coyotes to see
where they’re going and what they’re doing.


(Sound of tires on gravel)


Justin Brown is with a research project out of Ohio State University.
He’s just located the spot where a coyote is hiding. We can’t see him,
but we know he’s there because of the signal his collar is emitting.


“We very rarely see them, especially during the day. At the night —
during the night, occasionally we’ll get good visuals, but for the most
part during the day times you never see them.”


Brown and his colleagues are trying to figure out why there are more
coyotes in the suburbs and cities. One of the reasons is car and deer
accidents. Coyotes feed on the carcasses. The huge increase in Canada
geese is another reason.


“Food ranges from deer to geese to even just dog food people leave out.
There’s definitely a high variety of foods available to them. For habitat,
it can be anything, any little wood lot, anywhere that they can find a little
hiding spot for the daytime and then during the evenings they run (in) a
lot of areas you wouldn’t expect such as residential areas and
commercial parking lots. They pretty much run it all, anywhere that they
might come across a meal.”


You’d think there wouldn’t be that many places for a coyote to hide in
the city and suburbs. But, Brown says they hide in parks, golf courses, in
wood lots, graveyards… anyplace with a little cover. Brown’s research team
leader, Stan Gehrt, estimates there are something like two-thousand coyotes
in the Chicago metro area.Justin Brown says the truly amazing thing is that
coyotes have learned to adapt so well… and even survive a lot of automobile
traffic.


“We’ve actually seen animals where they’re actually figuring out traffic
patterns. They know which roads are going which ways. We’ll see them
cross roads where they’ll actually look only the direction traffic should
be coming and then go and then stop in the middle and look in the other
direction for traffic and then go. So, they’ve definitely figured out how
the road systems work. It’s just amazing to see how they survive in this
environment.”


And, the experts say, the coyotes are probably here to stay. Most
residents don’t want the police to shoot the animals. So some
municipalities tried to trap and relocate the animals to a more rural area,
but coyotes are very territorial, and they immediately head back to the
place where they were trapped. Often they’re hit by cars on the journey
back, but sometimes they make it home, and the predator in the suburbs
is back and hungry.

Designing Bird-Friendly Buildings

  • In Chicago, many migrating birds are attracted by the lights on tall buildings. This attraction causes some birds to crash into the buildings, often resulting in death. (Photo by Lester Graham)

Scientists estimate up to a billion birds are killed every year when they collide into building windows in the United States. Now, a group of bird watchers, biologists and architects are working together… hoping to lower the death toll. The Great Lakes Radio Consortium’s Lynette Kalsnes has the story:

Transcript

Scientists estimate up to a billion birds are killed when they collide into building windows in the United States every year. Now a group of bird watchers, biologists and architects are working together, hoping to lower the death toll. The Great Lakes Radio Consortium Lynette Kalsnes has the story:


If you call the group the Chicago Bird Collision Monitors, you’ll hear this message:


“If you have found an injured bird, please place the
bird gently in the bottom of a brown paper sack. A
grocery bag is just fine. Please put the bag with the bird in it in a quiet, dark place that’s warm. Inside, please.”


That’s the voice of the group’s founder and director Robbie Hunsinger. She’s followed those same instructions herself hundreds of times.


During migration season, in a single night, thousands
of birds fly over Chicago. They are attracted to the
lights on tall buildings and crash into the windows.
Hunsinger and other volunteers get up before dawn so
they can rescue the injured birds before the rats and
gulls get them.


After a morning of picking up injured birds, Hunsinger
has filled her car with brown paper bags containing
hurt swallows and cuckoos. Then, she’s driven up to 3
hours round-trip to get the birds to wildlife
rehabilitators.


She’s even cared for some of those birds herself.
Hunsinger has filled her music studio with mesh cages
and used up all her dishes for food and water. She says she decided to do something to help the birds three years ago after she saw 80 dead birds one morning in just a small area downtown.


“It was horrendous. Everywhere we looked, there were
birds, and they kept coming down. They were still
hitting when we were out there. So you’re standing
there, and birds were falling out of the sky.”


Hunsinger says she found the fallen birds clustered on
the sidewalks just as the busy city began to wake.


“It was rather surrealistic. Especially as the sun
started came up, and people started coming to work.
People were stepping over birds everywhere. People in
suits, people in high heels, coming in from the train
stations, going to their jobs in the Loop.”


Hunsinger says something changed in her that day. She
says she could no longer be an armchair
conservationist.
So, she formed a group of volunteers to help her save
the birds.


But rescuing injured birds didn’t seem to be enough.
Now she’s working with biologists, architects and bird-watchers to make buildings safer for birds.


Chicago already asks the managers of its tall
buildings to turn out the lights at night during
migration to avoid attracting the birds. But it’s
become clear that something more has to be done to
prevent so many birds from crashing into the building
windows.


This spring, the city and the Chicago Ornithological
Society will host what’s believed to be the first
conference on bird-friendly design. Those who’ve studied it say the problem is that birds
don’t recognize glass.


“The glass surface will act as a perfect mirror.”


That’s biology professor Daniel Klem Jr. of Muhlenberg College in Pennsylvania. He estimates that collisions with windows kill a billion birds a year in the U.S.


“A bird is not capable of determining that that image
on the glass surface is not a real tree. It attempts
to fly to it. Or it attempts to fly to light seen in
the window, as if it was a passageway to safety. And
the bird gets whacked and dies.”


Klem says installing windows at an angle or using
patterned glass can help. So can shades or
decals. Klem’s also pushing for research to develop special
glass or coatings that would be invisible to humans
but visible to birds.


It’s a new field. Limiting bird crashes isn’t part of
building design. Ellen Grimes is an assistant architecture professor at
the University of Illinois at Chicago. Grimes says
architects think about light, heat, power, water and
human traffic, but not bird traffic.


“When architects have approached sustainable design,
it’s been an engineering question. But there has not been a lot of consideration of
the biological interactions.”


Grimes acknowledges the issue of protecting birds
might be a hard sell because it might mean
compromising other design elements. But she’s hoping bird friendly design becomes as much
a part of green buildings as energy efficiency.


The rescue group’s Robbie Hunsinger says we share the
migrating birds with other nations. We have an
obligation to be good stewards of the birds.


“This can be fixed. These our our buildings. And we
should do it. We, by God, should do it.”


Meanwhile. Hunsinger is among a group of bird
watchers pushing for a center in downtown Chicago to
care for injured birds that collide with the building
windows. She’d like to keep the cages out of her home music
studio so she can actually practice music.

Chemicals that are suspected of being hazardous to human health
are being found in household dust. The chemicals are flame retardants
used in everything from carpet padding to TV sets. The Great Lakes Radio
Consortium’s Mark Brush has more:


The chemicals are known as poly-brominated-diphenyl-ethers, or PBDEs.
Scientists already knew that these flame retardant chemicals where found in
food. Now researchers are finding the chemicals, in household dust.


Heather Stapleton is a research chemist at the National Institute of
Standards and Technology. She authored a study recently published by the
American Chemical Society.


“I went out and collected some house dust samples from areas within the
Washington D.C. metropolitan area, and brought these samples back to the lab
and just did a preliminary measurement looking at PBDE’s in the house dust
samples and found surprisingly high levels in the house dust.”


Researchers are most concerned about how the chemicals affect developing
babies. Babies have more contact with household dust than the rest of us.
The chemicals have been found to cause developmental and nervous system
damage in rats and mice.

Safety Concerns About New Rat Poison Pill

Plaintiffs in a case before a New York Federal Court accuse the Environmental Protection
Agency of being too soft on protecting children from poisonous rat pellets. The Great
Lakes Radio Consortium’s Jenny Lawton reports:


The poisonous pellets aren’t just tough on rats. Some environmentalists say they’re
injuring young children as well. The Natural Resources Defense Council says more than
fifty-thousand children in the U.S. below the age of six have been sickened by rat poison
this year. In 1998, the EPA made a rule that required manufactuers to put a bitter taste
and a special dye in the pellets to keep children from eating them.


But three years later, the agency rescinded that mandate.


It said it had come to a “mutual agreement” with the rodenticide industry that those precautions
might be making the pellets less effective. But critics say that has put kids back in harm’s way.
Especially those living in low-income areas where rat infestation is a common problem.


Although the EPA won’t comment directly on the case, an agency report from 2001 argued that
when rodenticides are used correctly, and children are supervised around them, fewer accidental
ingestions happen.
