Chemistry on Titan Ideal for Life

Science sees life on Saturn's moon Titan.
Looking for alien life on planets like our own is tunnel vision. Believing that life can only exist on planets in the "sweet" belt is silly. The universe is a place of commonalities, yes. However, it has many types of environments from the very cold to the extremely hot.
Saturn's moon Titan
Saturn's moon, Titan, could have microbial life even though it is indeed frigid. The body has all the chemical requirements for life creation to occur. Titan is a carbon copy of Earth, except the lakes and rivers are methane not water.

Much of new science is bringing down temperatures so that chemical reaction can be controlled, so it is nonsense to premise that there is not sufficient energy for molecular interaction to happen at -179C on Titan. The key chemical hydrogen cyanide (HCN) is present on Saturn's satellite. 

Martin Rahm of Cornell university holds that the clouds of Titan could absorb energy from the distant Sun. The energy would be sufficient for hydrogen cyanide to form polymine chains which more effectively absorb sunlight.. Once triggered life would move forward.

Complex Chemistry to Strike a Match

The chemistry of lighting a match.
If you want to see in a dark room, light a match. It's simple isn't it? Not so fast, it is actually quite complex. A slow motion video at 40,000 frames per second shows the process. The completed video spreads out 0.10 of a second into one and a half minutes.
The process of lighting a match
Ignition takes place inside the "live" head of the match. It is just a little explosion followed by "slow" burn. The chemical blob does not burst into pieces. I holds together with small bits rolling to the outside surface.  It looks a planet exploding.

The main ingredient of a match head is antimony trisulfide: potassium chlorate makes this burn. Ammonium phosphate is also there to reduce particles from escaping, but some smoke is inevitable. Paraffin wax coats the match down to the halfway mark to ensure the flame continues on down the matchstick.

Powdered glass and red phosphate in the strike strip on the side of the matchbox ignites by friction when the head of the match is drawn across the strip. Oxygen comes in causing ignition turning the red phosphorous into white phosphorous. Fire and flame ensues from the heated potassium chlorate. Oxygen plus sulfide makes the flame burn longer.

So when you next light a match think of the complex process, then go on doing your mundane task. Lighting a fire? haven't you been told not to fight fire with fire?  Oh, you do fight/light fire with fire!

Body Rhythms are Set by Color as well as light

Light affects us in many ways. Nordic countries have light treatment for citizens who suffer from a depressive outlook due to lack of sunshine during winter. Their circadian rhythms are disrupted. Recently evidence points to the fact that color is important as well.
Dawn image picture
A study on mice indicates that color signals reaching the eyes are "stored" in the suprachiasmatic nucleus in the brain. It was thought only sunlight was responsible for setting the body clock. This has been brought into question, however. The research controlled the brightness of artificial sky and also added color blended into the level of brightness.

With only dawn sunlight in the test room mice seemed confused and their body temperatures lagged behind the norm by 30 minutes. When orange and blue was added to the dawn light the mice were perfectly normal in behavior and temperature.

It seems the light/color information is stored in suprachiasmic neurons in a special way. Biopsies show a time lag in the firing of these neurons which ties into low body temperatures. Mammals have evolved in tune with this planet. The animal to Earth "bonding" seems to be very close indeed.

Bull Ants Feed at Twilight

Bull ants do not feed during all daylight hours. Observation has shown that they feed at twilight. When the sun is brighter for longer for example in summer, or there is no cloud cover, bull ants forage for food later in the day. When the sun is darker, earlier, they search for food sooner in the day. It was believed that all insects fed according to circadian rhythms, but this does not seem to be the case.

Activity in the nest was affected by cloud cover. Outside activity that involves feeding occurs at twilight. Obviously, they are feeding during these short intervals to avoid predators: most animals that eat ants would be inactive at twilight.

Tests were done at ANU in Canberra. Bull ants were put in containers where diffused light was altered. It was found they only fed when the light was set at a particular low level. Evolution does take some winding paths. This shows though that evolution develops in a rational way.
