Here today, hair tomorrow

About a year ago I brought back a bottle of glacial meltwater from Alaska. It was frozen when I collected it and once melted looked perfectly clear. A few months ago, I noticed something that looked like a small clump of hair at the bottom of the glass, which has been growing slowly ever since (see photo, left). I have not removed the bottle top since I collected it.Can anyone tell me what it is and, if it is alive and growing, where is it getting its nutrients from?Sam Lessing, by email, no address supplied

Glaciers wear down the rock they'r sliding over, resulting in fine sand and mud being suspended in glacial meltwater. This accounts for the blue-green colour of glacial lakes and explains where your organism gets its nutrients.It is most likely a form of algae, as the glacial meltwater was unlikely to contain decaying plant material that a fungus could have thrived on. Given enough light, it can thrive inside the bottle and produce oxygen which may be expended by bacteria or by parts of the algae rotting. Being a closed ecosystem with only light coming in and heat getting out, it could go on for quite some time. Not unlike the earth itself in fact.

Recent discoveries on Mars are indicating that the presence of water not only supports life, but that the water molecules themselves may be the very basis for life itself i.e. the first single celled organisms were born of H2O molecules. Further to this, it has been long thought that organs such as eyes and nerves were some of the first to develop. Not so, apparently hair comes first. This may be an example of that however the only fact that puts this into doubt is that it’s usually eyebrows rather than long hair such as that pictured which comes first in most evolutionary paths.

It looks like algae. The same sort of algae that appears from nowhere in ponds (in UK we call it 'blanketweed'). This pond algae appears predominately in ponds that get full sunlight. Have you been keeping the bottle in a sunlit place?

The green alga Chlamydomonas nivalis, grows on glacier snow. Although sporadic amp; not too common, it appears as pinkish colonies on the glacier snow and in some glacier cravasses. it grows, through its full life cycle, in the cold amp; does not need to be thawed out. put it under a transmission light microscope and have a look.
