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.

That black mold you sometimes find in wet basements might cause
more trouble than you think. New research finds that toxins
produced by black mold are capable of killing cells that help us
smell. The GLRC’s Erin Toner reports:


Toxins found in the spores of black mold have been linked to
respiratory and neurological problems. But now, researchers at
Michigan State University have found that the toxins also affect
the nasal passages.


Veterinary Pathologist Jack Harkema was one of the researchers.
He says in the study, mice were given a small, single dose of black
mold toxin.


“When we examined these animals, we found that the cells that are
important to detect odors, or the sense of smell, that within 24
hours they died.”


Harkema says the toxins killed nearly 80 percent of nasal cells that
send signals to the brain. He says more research is needed to better
understand the effects of the toxin on people. That could be
important for thousands who’ve been affected by flooding,
including the disaster caused by Hurricane Katrina.
