Lullaby for Grown-Ups - Pino Forastiere

Another gifted acoustic guitarist comes to us via YouTube. Pino Forastiere performs Cammino with great skill and feeling. A penetrating piece, almost brooding, it transports the listener to another time and place where many possibilities exist beyond what might have been previously experienced.

Several months ago I blogged about Galaxy Zoo, a project that engages citizen scientists to help classify galaxies by shape. More than 150,000 people have taken part in Galaxy Zoo so far in an effort to classify almost a quarter of a million images. At the time of the blog post, Phase 1 was completed and Phase 2 was in the works.

Well, Phase 2 launched this week, so it's a good time to get on board if you'd like to help categorize the night sky. The human brain is better at this task than a computer, and it basically involves answering a series of questions about a galaxy's shape. It's a chance to view some lovely images while advancing astronomy research. Think of it as a way to stargaze without the freezing temperatures (at least for a while).

Lullaby for Grown-Ups - Alice Friend

Gifted artist Alice Friend provides this week's lullaby with her video Kokopelli's Magical Tour of Paintings, featuring her artwork and music. I find her music and imagery to be uplifting and delightful. I hope you enjoy it.

Luminous Life - Into the Woods

Softly glowing mushrooms rising from the forest floor - no wonder people in bygone times concluded that they had suddenly been transported to the realm of the faeries.

The strange bioluminescence of mushrooms and other fungi defies understanding. The usual reasons given for bioluminescence - mating, predation, defense, communication - don't seem to apply to luminous mushrooms, and no one seems to understand why they developed this ability.

Mushrooms aren't the only light-generating organisms in the woods. Slime molds, which are no longer considered fungi but classified as protista, are capable of bioluminescence, but that's mostly the tropical varieties. It can get confusing. One of my favorite stories about a cold-light encounter comes from the magazine The Smithsonian, which ran a photo essay some years ago featuring slime molds (images similar to these). In the next issue, there was a letter from a couple who told a story about how they went to their local parks department to get free wood chip mulch, which they spread in their yard. One night not long after, they noticed that a region of the wood chips was glowing. Not sure what to do and apparently alarmed, they turned the hose on it.

They wondered whether they had sprayed away a slime mold. But those intrepid suburbanites were most likely dealing with foxfire, another type of fungi that emits light.

Foxfire can be found on rotting wood in damp forests. The fungi will glow at temperatures as low as 34 degrees F, but the optimal temperature is 77. If you want to hunt foxfire, there are some great tips in this extension bulletin from the University of Georgia's School of Forest Resources. The tips include going out on overcast or moonless nights to spot the low-intensity green glow, and staying away from artificial lights to give your eyes time to adjust to the dark.

In the depths of the nighttime forest, mysterious lights beckon, inviting us to explore their domain. No need to grab the hose - just marvel at how the mundane by day becomes the wondrous by night.

Lullaby for Grown-Ups - Carly Simon

We're having a midwinter thaw right now in my area, which is lovely, but I can't help wondering when the cold will return. This week's lullaby is a reminder of summer evenings to come. Carly Simon performs that Beatles classic, Blackbird. I love the look of this video, and her wonderful performance.

Lullaby for Grown-Ups - Therese Honey

This week's lullaby is a wonderful, lilting song, Hewlett, arranged and performed by harpist Therese Honey. The harp has such a soothing sound. Relax and enjoy this lovely tune.
