Life is full of disappointments

July24

So it’s just not that Obama is acting like Bush on certain things, it a bit more personal. What happens when you find out that people you admire are bat-shit fucking crazy? So I’m reading about a celebrity “atheist” who seems to me to hate science. Especially the branch of science that I love the most, my little buddies the microbes.

Obviously I disappointed that someone doesn’t live up to my standards. So now I feel like a little kid that whining that there’s no Santa. Because after all, that’s life, where you have to deal with crazy Aunt Tilda in the attic.

Cool Stars Have Different Mix of Chemicals

April26

From the NASA Spitzer news page, A look at the chemicals around smaller and cooler stars than the sun show that they do not have hydrogen cyanide, but acetylene. The speculation is that ultraviolet light is involved in the creation of HCN. Also small stars have extreme magnetic bursts that can be disruptive for life. So the implications for life on planets around these stars seems to be less likely than sun-like stars.

Less Nickle means more life

April10

From Universe today, a look at banded iron formations, show the decrease of nickel in seawater over time. It is speculated that methanogens, which are known to need nickle, became less abundant and lead to the rise of oxygen producers and more complex life.
