A botanist has documented what he’s
calling the “fastest flight in nature.” Tana
Weingartner explains:

Imagine this: a You-Tube video showing tulip-shaped fungi recoiling and
launching spores like wet cannonballs.

(sound of music)

Nicholas Money is a botanist at Miami University. He and a team of
researchers have used high speed cameras to capture, for the first time, fungi
launching spores.

“Fleas accelerate at 200 g, but we’re clocking these fungi moving at close to 200,000
g in terms of their acceleration. These are astonishingly fast movements.”

Fungi cause billions of dollars in crop damage each year.

Money says knowing how these spores move around can help prevent these
losses. He also says it’ll help allergen and pharmaceutical researchers too.

Cold War Clean Up Near Completion

Clean up at a former Cold War-era uranium processing plant is nearly complete. A train carrying the final load of radioactive waste is now making its way from southwest Ohio to a disposal site in Utah. Tana Weingartner reports:

Clean up at a former Cold War-era uranium processing plant is nearly complete. A train carrying the final load of radioactive waste is now making its way from southwest Ohio to a disposal site in Utah. Tana Weingartner reports:


It took three engines to slowly haul away the last 60 railcars full of radioactive dirt, concrete and debris. The waste came from the former Fernald Uranium processing facility in southwest Ohio. During the Cold War, workers at the top-secret plant processed uranium for nuclear weapons. Johnny Reising is the Fernald Site Director for the Department of Energy.


“It’s one of the largest waste shipping operations that the department of energy has had to date. There will probably be larger ones in the future, but to date this is the largest that’s taken place.”


Reising says the overall clean up is ahead of schedule and expected to cost about $70 million less than the projected $1.9 billion price tag.


Following completion, the D.O.E.’s Office of Legacy Management will maintain Fernald as an undeveloped park.

Fossils Connect Gap in Evolution

A team of scientists has found fossils that connect a six-million year gap in the chain of human evolution. The GLRC’s Tana Weingartner reports:

A team of scientists has found fossils that connect a six-million year gap
in the chain of human evolution. The GLRC’s Tana Weingartner reports:


Scientists found fossils of the species Australopithecus Anamensis in
Ethiopia. The fossils are just over four million years old. Researchers
say the fossils are a clear link between two previously known species of
ape-man.


Dr. William Hart is a team member and a Professor of Geology at Miami
University in Ohio.


“It really shows us evidence of the way early humans evolved in terms of
characteristics of their teeth, as eating habits changed. How other aspects
of their anatomy evolved through time. This is the first time we’ve had
that kind of a snapshot really.”


Similar fossils were first found in Kenya in the 1990’s, but Hart says this
find is special because the fossils are sandwiched between fossils from
the other two species.


The findings were reported in the journal Nature

Termite Worries More Myth Than Fact

An email is spreading across the Internet warning about termites in
mulch stockpiles from the hurricane ravaged Gulf Coast. As the GLRC’s
Tana Weingartner reports, the email is more rumor than fact:


The email says Formosa termite infested trees downed by Hurricane
Katrina are being mulched and sold off by the state of Louisiana. The
writer warns the infected mulch could end up at your local big box
hardware store.


The Mulch and Soil Council’s Executive Director says that’s just “not
true.” Robert LaGasse says the well-monitored clean up operation and a
preexisting quarantine banning wood products from being shipped out of
the area are part of what keeps the termites from spreading.


“We’ve never had an infestation issue with termites in mulch, in bagged
product.”


LaGasse adds even if the mulch was shipped out of the region, the
chipping and grinding process along with the heat generated by the
mulch would be enough to kill any termite.


The Formosa termite has been a problem for parts of the South since it
was first brought into the country after World War II.

Bed Bugs Biting Again

Health officials across the country say some nasty night critters are making a comeback. Bed bug cases are up. And in 2005, they were reported in 43 states. The GLRC’s Tana Weingartner reports:

Health officials across the country say some nasty night critters are
making a comeback. Bed bug cases are up, and in 2005, they were reported
in 43 states. The GLRC’s Tana Weingartner reports:


It turns out your mother knew what she talking about, when she
reminded you to “sleep tight” and “don’t let the bed bugs bite.” The
blood-sucking insects are popping up in hotels and homes around the
country.


Steve Chordas is a public health entomologist with the Ohio Department
of Health. He blames increases in travel and the banning of some
pesticides for the bed bug resurgence, but, he says, the bugs are more of
a nuisance than a public health threat.


“There’ve been some diseases that have been isolated from the bed bugs,
but it’s not been shown, scientifically at least, that these are able to be
vectored by the bed bugs or transmitted from the bed bugs to a new
victim.”


Bed bugs are like tiny hitchhikers that can hide in your luggage and
clothing if you stay in an infested hotel room. Extensive cleaning and
insecticides are usually needed to get rid of a bed bug infestation.

Government workers are slogging around in man-made wetlands looking for salamanders. Back in the 1950’s, the United States government selected a plot of land to be the home of its newest uranium processing plant. Since the end of the Cold War, the now-closed nuclear processing plant has been undergoing the long and arduous task of returning to its natural wetland state. The Great Lakes Radio Consortium’s Tana Weingartner reports on the search for salamanders at the site, and why their presence is so important:


It’s a cold, windy day in late March as specialists from the Ohio Environmental Protection Agency head out to check their traps at the Fernald Nuclear Plant. The 1050-acre facility sits in a rural area just 18 miles north of Cincinnati. Although the EPA is in charge of cleaning up the uranium contamination here, today they’re on a different mission. Today they’re hunting salamanders.


“Salamanders basically are a sign of an established wetland usually, and in this case would show that we put a wetland in a location where salamanders need additional breeding habitat.”


In other words, Schneider says the presence of salamanders indicates the first level of success for these manmade wetlands. The wetland project is one of several ways the EPA is ensuring Fernald is properly restored to its natural state.


“Well, we’re looking forward to the day when we get the site cleaned up, and it can be like a land lab, and people can bring kids out here and do environmental education on the importance of wetlands, and it’s going to make a great contrast with what used to be here and the environmental contamination with the environmental benefit the facility is providing down the road.”


Today, the site is 70 percent certified clean, and officials expect to finish the cleanup by June 2006. Creating healthy wetlands full of insects, amphibians and salamanders is one of the first steps to success.


“So the method here is to set ten traps equidistant, hopefully, around the perimeter of the wetland. And they’re passive traps, whereby animals that are moving over the course of the 24 hours or so that the traps have been in, will bump into the traps and it’s a funnel that directs them into the center part of the trap, and they’re held in there until we release them.”


(splashing sound)


Schneider and his team laugh and joke as they pull the traps up by brightly colored ribbons. Train horns and construction noises mix with bird calls – one a reminder of what has been, the other a sign of what’s to come.


“That’s probably a one-year-old bullfrog there and then these big guys are dragonfly larvae and these other guys are back swimmers. Mayfly larvae and dragonfly larvae are both good indicators of high water quality.”


The third pond, or vernal pool, turns up 46 tadpoles and a tiny peeper frog, but no salamanders.


(truck door slams)


So it’s back in the truck and on down the dirt road to where several more wetland pools sit just across from the on-site waste dump. That dump will be Fernald’s lasting reminder of its former use. These pools are younger and less established, but they do offer hope. Last year, adult salamanders were found in the one closest to a clump of trees.


Each spring, as the snow melts away and temperatures rise, salamanders venture out in the first 50-degree rain to begin their search for a mate. Schneider had hoped warm temperatures in late February and early March prompted “The Big Night,” as it’s known.


“So, no salamanders today?”


“No salamanders today. I think we learned a little bit about the difference between wetlands that are three years old. We saw a lot more diversity in the macroinvertebrates, the insect population, than we have down here.”


Perhaps the salamanders haven’t come yet, or maybe they have already come and gone, leaving behind the still un-hatched eggs. Either way, the team will check back again in April and a third time in late May or June.


“And we have high hopes, high hopes, high apple pie in the sky hopes. That’s the kind.”
