Science Links

A collections of links to interesting articl;es on the origin of life and other things, updated as and when I come across them.

Building blocks of life
In their paper published in the journal Nature Chemistry, the team describes how they were able to map reactions that produced two and three-carbon sugars, amino acids, ribonucleotides and glycerol—the material necessary for metabolism and for creating the building blocks of proteins and ribonucleic acid molecules and also for allowing for the creation of lipids that form cell membranes.

Experiments performed by ETH scientists have shown that it is remarkably easy for protein-like, two-dimensional structures—amyloids—to form from basic building blocks. This discovery supports the researchers' hypothesis that primal life could have evolved from amyloids such as these.

A team of researchers with members from Syracuse University and the University of California, has found that naturally forming peptides can self-assemble into catalysts. In their paper published in the journal Nature Chemistry, the team describes how they designed seven peptides, allowed the resulting molecules to self-assemble into amyloids and then noted how many of them could catalyze the hydrolysis of esters.

Dino-feathers
Their work, which included samples from many stages in the evolution of feathers, bolstered the findings of other scientists who've suggested that dinosaurs (winged and otherwise) had multicolored and transparent feathers of the sort you might see on birds today.

Cult Psychology

This is quite different. it is a Wiki page about a group of social psychologists investigating how cults deal with failed prophecies.
http://en.wikipedia.org/wiki/When_Prophecy_Fails
The group of believers, headed by Keech, had taken strong actions to indicate their degree of commitment to the belief. They had left jobs, college, and spouses, and had given away money and possessions to prepare for their departure on a flying saucer which was to rescue the group of true believers. She claimed to have received a message from a fictional planet named Clarion. These messages revealed that the world would end in a great flood before dawn on December 21, 1954.

The prophecy failed, but within hours the group had rationalised that God had saved the world, and so became even more convinced that they were right.

Afternoon, December 21. Newspapers are called; interviews are sought. In a reversal of its previous distaste for publicity, the group begins an urgent campaign to spread its message to as broad an audience as possible.
Anyone else see a link to certain other religions?
