A new national report recommends building more nuclear power plants in the
U.S. Chuck Quirmbach reports:


A study by the National Research Council urges the Department of Energy to
place greater emphasis on identifying sites for more nuclear power plants and
improving plant designs.


University of Wisconsin Engineering Physics Chairman Mike Corradini served on
the committee. He says there’s a need for more large scale electricity generation
that doesn’t add to carbon emissions:


“And it’s important we do it with a fuel source which is relatively secure. Nuclear
power is a logical way to do this and therefore that should be the major focus in
the next 10 to 15 to 20 years.”


Another part of the national report recommends scaling back of a new program to
speed the reprocessing of spent uranium fuel to share with other countries. Nuclear power opponents worry about radioactive waste and want to block
proposed subsidies for the nuclear power industry.

Insights Into Animal Diseases

A new study says the spread of animal sicknesses such as Chronic Wasting Disease in deer may
happen more easily because of the way a protein binds to soil. Chuck Quirmbach reports:

A new study says the spread of animal sicknesses such as Chronic Wasting Disease in deer may
happen more easily because of the way a protein binds to soil. Chuck Quirmbach reports:


Scientists have known that when an infected animal puts prions, or abnormal protein agents, in
soil the prions can stay alive for a long time. A study has looked at different types of common
soil minerals and found that a type of clay is an especially good binding agent for the prions.


University of Wisconsin researcher Judd Aiken says the link is so good that there’s a much higher
risk of the infection spreading when another animal grazes in the area:


“There was an enhancement of infectivity and we’re estimating roughly a 700-fold enhancement
of infectivity.”


Aiken says it might mean that government efforts to stop the spread of deadly animal brain
diseases like Chronic Wasting Disease in deer or scrapie in sheep may only be as effective as the
type of soil where the animals live.

Some Extreme Climates Disappear

A new study predicts global warming will prompt some types of climates
to disappear from parts of the world. Chuck Quirmbach reports:

Transcript

A new study predicts global warming will prompt some types of climates
to disappear from parts of the world. Chuck Quirmbach reports:


Scientists asked that if the planet warms up, where would new climates
be created and where would existing climates disappear? Geography
professor Jack Williams heads a research team at the University of
Wisconsin and University of Wyoming.


Using computer modeling, he predicts by the year 2100,the main changes
will be in low-lying tropical areas, at the top of very high
mountains, and at the poles:


“So the warmest areas get warmer and are first to move outside the
range of what we experience at present and then the coldest areas,
also get warmer… so that these sets of cool or cold climates
disappear as we move to a warmer world.”


Williams says where climates disappear, that will put local species in
danger. He says it’s not clear what the new climates will be like.

Study: The Human Factor and Wildfires

Wildfires account for a lot of property damage every year in the US, and forestry officials are constantly assessing how to predict when and where they will occur. One researcher says a largely overlooked predictor is the human factor. Brian Bull reports:

Wildfires account for a lot of property damage every year in the US, and forestry officials are constantly assessing how to predict when and where they will occur. One researcher says a largely overlooked predictor is the human factor. Brian Bull reports:


Generally, vegetation and terrain are examined to figure out fire-prone areas. But Alexandra Syphard, a University of Wisconsin researcher, says most blazes happen along developments or roads, where forestland borders urban areas. Syphard says while she used southern California for her research model, her findings can be applied anywhere there is natural terrain along with man-made roads and structures.


“While the variables may differ a little bit in their degree of influence in different regions, you can still use these same kinds of methods to account for all of the factors that influence fires, as opposed to what a lot of people commonly do which is just simply looking at areas where fuels have accumulated.”


Syphard presented her research at the Third International Fire Ecology and Management Congress. She says variables such as terrain, climate, and vegetation still figure largely in active burns but that the human factor needs to be reviewed more closely.

Could Humans Get Chronic Wasting Disease?

A disease that infects deer and elk has been alarming wildlife officials
and hunters for years, but now it seems the disease could be more
dangerous than previously thought. The Great Lakes Radio Consortium’s
Christina Shockley reports:


Chronic Wasting Disease, or CWD, affects the brain tissue of deer and
elk. Sponge-like holes form in the brains of sick animals. The deer
begin to waste away, become weak, and then die.


Since CWD was discovered in Colorado nearly forty years ago, wild deer
in nine other states have tested positive for the disease. Little is known
about CWD – including how to stop it.


What scientists do know is that the infectious proteins-called prions –
thought to cause CWD are found in the brain and spinal cord areas of
infected animals, but officials still don’t have the answer to the big
question.


Judd Aiken is a professor of Animal Health and Biomedical Sciences at
the University of Wisconsin.


“The ultimate question is whether venison from infected animals, CWD infected
deer, poses a risk to humans. Clearly the first question that needed to be
asked and addressed was whether there was infectivity in muscle.”


Recent findings say there is.


Researchers at the University of Kentucky injected muscle from an
infected deer into the brains of genetically altered mice. The mice
displayed signs of CWD. This is the first time the infectious proteins
blamed for CWD have been found in deer meat.


The finding raises questions about whether eating venison is safe.
Researchers including Aiken say the study is important, but has limits.
For example, he says it doesn’t replicate what would happen in real life.
Plus, he says it’s probably unlikely humans can even get CWD. He says
studies suggest it’s difficult for the disease to jump to other species. Still,
he urges caution. Hunters should get the meat tested before they eat deer
from an area where CWD has been found.


“I, in no way, can advocate the consumption of infected deer, and indeed,
I would suggest due to the limitations of the CW tests, I don’t advocate
the consumption of deer obtained from a CWD endemic area.”


Even if the test comes back negative, Aiken says a negative result isn’t
always accurate, and infected animals in the beginning stages of the
disease can look and act normal.


(Sound of sporting goods store)


John White is a deer hunter from Sheboygan, Wisconsin. He’s in the
hunting section of a nearby sporting goods store. White isn’t too
concerned about Chronic Wasting Disease.


“Not a whole lot of people are worried about it. I mean, when it first
came out, some people were a little leery about it and didn’t want to hunt
that year, but they kinda got over it. I’m not really worried about it being
in the meat at all, because by the time the test comes back I’ll probably
have the deer eaten already and then it’s already too late.”


State wildlife officials say… that’s not a good idea. They recommend that
if you hunt deer in areas where the disease has been found, get the deer
tested before eating it. That message hasn’t changedā€¦ since learning the
prions could be in the meat. Some argue… it should change.


John Stauber is with a government watchdog group in Wisconsin, and
is co-author of “Mad Cow USA: Could the Nightmare Happen Here?”
He says officials are keeping quiet about the risk of CWD so they don’t
lose revenue from hunting licenses.


A large portion of state conservation agency budgets are dependent on
fees from hunting licenses. He says all deer that die should be tested for
the disease. Stauber also says CWD is a major human health concern.


“The biggest risk might not be the people who would die from
eating venison, but rather, the people who would die from the
contamination of the blood supply. This is a problem that would unfold
not in days or months or years, but even over decades.”


Stauber says it’s just a matter of time before Chronic Wasting Disease
spreads to peopleā€¦ he says some might even have the disease already,
and not know it.


But researchers like Judd Aiken from the University of Wisconsin say
people shouldn’t over-react.


“People should be concerned, but I don’t want people to panic, either. If
you think you may have consumed venison from infected animals, I don’t
think it’s likely that you’ll ever develop a human prion disease.”


But, Aiken says there’s too much we don’t know about the disease, and
since studies can take years to complete, we might be in the dark for a
while longer.

Women Scientists Still Facing Career Barriers

A new report concludes women scientists at universities still face career barriers that most men don’t. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story.


A program developed by the National Science Foundation looks at efforts to advance women in scientific careers. Leaders of the program have just published a paper in Science Magazine that concludes women scientists are making some gains on campus, especially in the biological sciences.


University of Wisconsin – Madison professor Jo Handelsman co-authored the report. She says at some universities thogh, many women still face hostile climates, lack of training opportunities, and unconscious bias. Handelsman says both men and women may hold the same biases.


“So a lot of people have assumed that if there’s a woman on the search committee or a woman making decisions, then there isn’t going to be a prejudice against women, and that simply isn’t true.”


Handelsman says one goal is to make academic hiring and tenure committees aware of the issue, so they can ask themselves if they’re holding all candidates to the same standard.

Development Triples in National Forests

One of the most comprehensive studies of development in and around national forests spells out the size of some potential threats. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

Transcript

One of the most comprehensive studies of development in and around national
forests spells out the size of some potential threats. The Great Lakes Radio
Consortium’s Chuck Quirmbach reports:


The study by the University of Wisconsin-Madison looked at a half century of
government census data on national forests. The results show the number of
housing units within national forest boundaries tripled between the years 1950
and 2000. There’s also been a big increase in development within a 30 mile
radius of the forests.


Researcher Volker Radeloff says development has brought in more invasive
species… and narrowed the wildlife corridors between forests. He says he realizes
many communities want to grow.


“The danger is if it’s not occurring in a consensus driven or planning process then the
decisions will be made for these communities… and what that means is increasing isolation of
these forests and strong environmental effects.”


Radeloff says in the Great Lakes region, much of the development in and around national forests
is from people building second homes or recreational housing.

Some scientists contend that land use by humans has become a top threat to the planet’s ecosystem. The Great Lakes Radio Consortium’s Chuck Quirmbach reports.


People in cities and towns often spend hours debating local land use issues, but a group of scientists says there should also be a focus on the larger topic of widespread conversion of natural landscapes to uses like urban development and agriculture.


Jonathan Foley is a climatologist at the University of Wisconsin – Madison and lead author of a new study published in the journal Science. He says the Midwest sees its share of large land use changes.


“We grow a lot of corn and soybeans and other crops. But we do so, unfortunately, with quite a bit of damage to some of our environment: water quality, leaching of nitrogen and phosphorus into our lakes and groundwater and streams.”


Foley says the Midwest could look at changing farm subsidy programs to help farmers use better environmental practices. Globally, he says six billion people are competing for food, water, and shelter, and their land use decisions are transforming the planet.

There are several groups in the region working to protect and restore the
endangered Karner blue butterfly. Now these efforts could be helped by a
new computer mapping and statistical modeling technique. The Great Lakes
Radio Consortium’s Chuck Quirmbach has more:


Habitat maps for endangered species can be based on broad general
estimates. But some scientists hope a combination of computer
software and data such as soil type and vegetation will lead to
more accurate information on where the Karner Blue butterfly lives.


David Mladenoff is a professor of Forest Ecology at the University of
Wisconsin – Madison. He says having a better idea of the butterfly’s
habitat might save companies money on things like surveying costs.


“In other words, if they say we’re planning on doing work on this utility
right away or potentially harvest this area of forest, is this even
a place we have to be concerned about for the Karner Blue butterfly
occuring?”


The U.S. Fish and Wildlife Service, a state agency, and some power
companies are funding a computer mapping project in Wisconsin.
Scientists say the same technique could be used in other states.

New Study Shows Long Term Effects of Fertilizers

A new study suggests the build-up of phosphorus in lakes may cause problems
for hundreds of years. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:


Many farmers and other landowners use phosphorus-rich fertilizers on their property, but when the chemical runs off into lakes and streams, it can lead to algae blooms, depletion of oxygen, and fish
kills.


New research says it can take decades or hundreds of years for phosphorus to cycle out of a watershed. University of Wisconsin – Madison Professor Stephen Carpenter did the study. He says the effects won’t be as long-lasting if more phosphorus controls are put in place.


“For example we could develop more buffer strips, restore more wetlands, move point sources away from streams and lakes and maybe even innovate new technologies for keeping phosphorus on the
land.”


Farm groups say many of their members are trying to reduce soil erosion and chemical runoff. Carpenter says that’s true, but he says in some watersheds, much stronger action is needed.
