New study examines bioluminescence in fungi
FRISCO — Dartmouth scientists say they’ve figured out why some mushroom species glow in the dark, and like with many other biological mysteries, the answer is both simple and complex at the same time.
Reporting their findings in the Cell Press journal Current Biology, the researchers said the light attracts the attention of beetles, flies, wasps, and ants who spread the spores, helping the fungi colonize new territory.
The study also shows that the mushrooms’ bioluminescence is under the control of the circadian clock. In fact, it was that discovery that led the researchers to suspect that the mushrooms’ light must serve some useful purpose. Continue reading

Scientists say soil microbes key to fungi’s distinctive aroma

FRISCO — Mushroom season may be over the Colorado high country, but in parts of Europe, it’s the peak of the truffle season, as hundreds of gourmets scour oak forests to find the fragrant buried fungi, often with the help of animals.
Now scientists say that the scent of the hidden edible treasures is largely produced not by the fungi itself, but by soil bacteria trapped inside truffle fruiting bodies, a discovery of interest not only to mycophiles, but to scientists speciazing in food flavors.
The study involved white truffles from the Piedmont region in Italy, which can cost up to 5,000 Euro per kilo (about $4,000 a pound), and black truffles from the Périgord region in Southern France. Particularly large specimens even fetch prices of up to 50,000 Euro per kilogram at auctions. Continue reading

Fresh blooms …
Tundra wildflowers, Loveland Pass, Colorado.
FRISCO — It’s that sweet time of year when high country wildflower start to go nuts, I’ve never seen as many tall blue penstemon as in the past few days, which makes me realize that the flowers have their own cycles and rhythms that we can’t begin to understand yet. So on Tuesday morning, I ventured up to the Shrine Pass area to have a look, but the bulk of the blooming is still ahead. Still, using back-lighting, careful composition and the iPone camera’s HDR option, I was able to scare up a couple of decent shots. Continue reading

FRISCO — Clouds. We often take them for granted, or see them as a nuisance if we’re in the mood for a bright, sunny day, but clouds are, of course, an essential part of the cycle of life on this planet, transporting water vapor throughout the atmosphere, distributing moisture and affecting climate in ways we are just beginning to understand. For a photographer, clouds are often the perfect foil for landscape shots, helping to soften the light and add drama to what otherwise might just be a blank space. Even if you’re not a photographer, take some time one of these days to check out what’s going on in the sky above you. Visit our online gallery at Fine Art America for more Summit County landscape and nature shots.
