Climate physics - global warming

The talk is planned as an overview of the contemporary climate physics. In the first part physical principles of the climate system will be reminded. Then history of climate science, beginning from Joseph Fourier through John Tyndall, Svante Arrhenius to Edward N. Lorenz and modern times will be stressed. Observing systems and theoretical methods commonly used in climate research will be discussed after the introduction. Particular attention will be paid to the attribution of the recentclimate change. Advances in climate science in the context of the forthcoming 5th Assessment Report of the Intergovernmental Panel on Climate Change will be summarized in the final part of the talk.

Mechanical stability of Proteins and Virus Capsids

Molecular dynamics of proteins within coarse grained models have become auseful tool in studies of large scale systems. The talk will discuss twoapplications of such modeling that relate to single-molecule manipulation.The first is a theoretical survey of proteins' resistance to stretching anda discovery of novel mechanisms that cause it. These mechanisms aretopological in nature and may lead to characteristic forces that are largerthan in the silk of spiders.

The second application involves studies of nanoindentation processes invirus capsids and elucidates their molecular aspects by showing deviationsin behavior compared to the continuum shell model. We also demonstrate thedependence of the corresponding Young modulus on the effective averagecoordination number that characterizes interactions of a single amino acidwith other amino acids in the capsid.

Cherenkov Telescope Array - the future of gamma-ray astronomy

High energy gamma ray astronomy has undergone a large development in the last few years. The results from Cherenkov telescopes like HESS, MAGIC and VERITAS observatories have open new horizons and showed multiple new sources. I will review the very high energy sky, and present the status of the preparations for Cherenkov Telescope Array - the next generation Cherenkov observatory.
