Welcome to the society for things cut in half. We have made much progress, but there are still many things not cut in half.

The corporate philanthropy goes beyond underwriting for pubcasting to ‘goodworks’ for feel good points.
Prof Steven Benner, of the Westheimer Institute of Science and Technology in Gainesville, US.
Reported his research at the Goldschmidt Meeting in Florence, Italy.
Building blocks of life: Molecules – RNA, DNA and proteins.
“Simply adding energy such as heat or light to the more basic organic molecules in the “soup” does not generate RNA. Instead, it generates tar.”
RNA for example could be formed by “templeting” atams into the shape – by use of a Crystal base.
Prof Benner argues that: minerals most effective at templating RNA would have dissolved in the oceans of the early Earth, but would have been more abundant on Mars.
boron and molybdenum are key in assembling atoms.
boron minerals help carbohydrate rings to form
molybdenum can take that intermediate molecule and rearrange it to form ribose, and hence RNA.
