"Perspectives in Chemistry: From Supramolecular Chemistry towards Adaptive Chemistry"
More information Time 11:00 - 12:30Location Gerhard M.J. Schmidt Lecture HallLecturer Prof. Jean-Marie Lehn, ISIS, Universite de Strasbourg, France Organizer Faculty of ChemistryContact Abstract Show full text abstract about Supramolecular chemistry is actively exploring systems under...» Supramolecular chemistry is actively exploring systems undergoing self-organization, i.e. systems capable of spontaneously generating well-defined functional supramolecular architectures by self-assembly from their components, on the basis of the molecular information stored in the covalent framework of the components and read out at the supramolecular level through specific non-covalent interactional algorithms, thus behaving as programmed chemical systems.
Supramolecular chemistry is intrinsically a dynamic chemistry in view of the lability of the interactions connecting the molecular components of a supramolecular entity and the resulting ability of supramolecular species to exchange their components. The same holds for molecular chemistry when the molecular entity contains covalent bonds that may form and break reversibility, so as to allow a continuous change in constitution by reorganization and exchange of building blocks. These features define a Constitutional Dynamic Chemistry (CDC) covering both the molecular and supramolecular levels.
CDC introduces a paradigm shift with respect to constitutionally static chemistry. It takes advantage of dynamic diversity to allow variation and selection and operates on dynamic constitutional diversity in response to either internal or external factors to achieve adaptation.
CDC generates networks of dynamically interconverting constituents, constitutional dynamic networks, presenting agonistic and antagonistic relationships between their constituents, that may respond to perturbations by physical stimuli or to chemical effectors.
The implementation of these concepts points to the emergence of adaptive and evolutive chemistry, towards systems of increasing complexity. -

Life Sciences Dept, Ben Gurion University of the NegevOrganizer Department of Brain SciencesContact Abstract Show full text abstract about From detecting food to locating lurking predators, visual se...» From detecting food to locating lurking predators, visual search -- the ability to find an object of interest against a background -- needs to be accurate and fast to ensure survival. In mammals, this led to the development of a parallel search mode, pop-out, which enables fast detection time that is not dependent on the number of distracting objects. Although it may be beneficial to most animals, pop-out behavior has been observed only in mammals, where its neural correlates are found as early as V1 in contextually modulated cells that encode aspects of saliency. I will describe our recent findings of pop-out visual search in the archer fish and discuss possible implications about universality of visual search among vertebrates. -

How will the James Webb Space Telescope measure First Light, Reionization, and Galaxy Assembly: The New Frontier after Hubble
More information Time 10:15 - 11:15Location Nella and Leon Benoziyo Physics BuildingLecturer Rogier A. Windhorst, Arizona State University Organizer Nella and Leon Benoziyo Center for AstrophysicsContact Abstract Show full text abstract about I will review how the 6.5 meter James Webb Space Telescope (...» I will review how the 6.5 meter James Webb Space Telescope (JWST) --- after its
launch in 2018 --- can measure the epochs of First Light, Reionization, Galaxy
Assembly, and Supermassive Black-Hole Growth, building on recent results from the
Hubble Wide Field Camera 3.
First, I'll briefly summarize the significant technical progress on the design
and fabrication of JWST: more than 98% of its launch mass has been built, passed
final design, or is being built as of spring 2015. All JWST's 18 flight mirrors
have been gold-coated with an optical performance that meets or exceed specs. All
of JWST's scientific instruments were delivered to NASA GSFC and tested from mid
2013--2015. I will briefly summarize the path from today till launch, planned
with an Ariane V for October 2018.
Next, I will briefly review the search for the first galaxies at redshifts z=9-11
(age ~0.5 Gyr) in the Hubble UltraDeep and Frontier Fields, and their current
limitations. I will show what combination of area, depth, and wavelength coverage
are needed for JWST to detect a sufficient number of First Light objects, and to
measure their evolving luminosity function (LF). JWST will map the epoch of First
Light through the so-called Population III-star dominated objects at redshifts
z~8--15, and its transition to the first Pop II stars in dwarf galaxies at z~6 in detail.
I will argue that gravitational lensing by the most highly-concentrated rich
foreground galaxy clusters will need to be used to maximize the number of First
Light objects (z~>12-15) detected with JWST. Last, I will address how many random
Webb Deep Fields (WDFs) may need to be observed with JWST to see First Light,
compared to the best lensing targets.
