In this talk, Roger E. Summons outlines approaches to seeking evidence of life in Earth’s oldest sedimentary rocks and shows, by analogy, how the Mars Science Laboratory mission is designed to investigate Mars’ capacity for supporting a biosphere.
No one knows when life first colonized planet Earth, nor if or when Mars ever supported life. We see numerous, unequivocal lines of evidence for life on Earth from some 3.5 billion years ago to the present day. But the further back in time we look, the more clues about our earliest ancestors are clouded by doubts, uncertainties and controversies.

In this talk, Mike Shelley discusses problems in fluid-structure interaction ranging from the macroscopic, i.e. flapping of flags and bending of tree leaves, to the micro – collective behaviors of micro-organisms and the transport of subcellular structures.
Autism and epilepsy are often comorbid disorders with overlapping epidemiology, genetics, clinical features, neuroanatomic abnormalities and neurophysiological mechanisms. Defining the genetics and clinical features of individuals with comorbid autism and epilepsy is ongoing, and development of genotype-phenotype correlations has just begun. Understanding shared and distinct mechanisms underlying autism and epilepsy is likely to improve prognosis, therapy and prevention.

On November 1, 2013, the Simons Foundation hosted the sixth annual New York Computer Science and Economics (NYCE) day.
Burgeoning evidence shows that in typical development, the ability to structure actions according to intentions emerges during infancy. And recent evidence reveals that infancy is a period of rapid change and development in this ability. Early social knowledge depends critically on infants’ active engagement with the physical and social world.

The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) near Geneva, Switzerland has performed spectacularly well in its first major running period: from December 2009 through February 2013. Data of unprecedented quality and quantity have been recorded for proton-proton collisions at energies of 7 and 8 trillion electron volts — the highest energies ever obtained.
