Roadsides may provide butterfly corridors
...oads has several drawbacks, including being hit by cars
and being contaminated by the heavy metals in exhaust. So the big question about restoring roadsides is: Do the benefits of this additional habitat outweigh the risks? "We don't know the answer to this for any species," says Ries. The answer may vary...

are very dear to our culture. Clearly the message is getting out, but it is not affecting behavior." Of the respondents, 79 percent said they regularly commuted to work and 5 percent said they sometimes commuted. Seventy-five percent of commuters...
Evidence links protein damage to Parkinson's
...much like oxidation causes rust damage to metal in cars
and buildings. This damage has been implicated in causing neurodegenerative disorders. "We found that alpha-synuclein itself is a target of oxidative stress, specifically nitration, within these lesions, " says Lee. "This is the first time anybody ...
