“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.
