“Planets and perception”
By Professor Giuseppe Longo, Italy

The talk focuses on some aspects of the history of astronomy which deal with the complex interaction between simple optical systems, human vision and atmospheric effects.

The talk will cover many interesting anecdotes: from the man on the Moon and the color of our satellite,to the color of Sirius, to the phases of Venus and the channels on Mars.

Behind each of these phenomena there are both interesting physics and an even more interesting social background.

“New Genes from Old”
By Dr. Mary Anne Clarke, USA (SL Max Chatnoir)

Where do new genes come from?  The origins of genes probably  lie with events in RNA world, but since DNA became the primary genomic material, new genes seem to be derived from old genes — both transferring them from species to species and modifying gene copies within and between species.  We’ll look some examples of gene origins:  the production of simple alleles, the modification of gene copies, and the acquisition of genes from other species, and the construction of new genes from old DNA sequences.
