Leena Jukka: Listen to your data, interview with
Professor Bruce Walker from the Georgia Institute of Technology “The human auditory system has superior
pattern recognition skills compared with the visual system, but sound is still
underused in displaying information.”
Tuomo Kauranne, Harri Auvinen and Heikki Haario,
Lappeenranta University of Technology: What is the weather like today? “Weather
forecasts and climate simulations can be improved with faster supercomputers,
better models of atmospheric dynamics and more advanced data assimilation
methods. The most dramatic algorithmic development in weather models over the
last twenty years has taken place in data assimilation.”
Ilkka Hanski and Otso Ovaskainen, University of Helsinki: The flight of a butterfly poses challenging questions from molecules to landscapes. “By studying the occurrence, ecological dynamics, genetic composition, and local evolutionary adaptations of the butterfly in this network we may learn a great deal about metapopulations.”

Mikael Peräkylä, University of Kuopio:
Theoretical studies of receptor-ligand systems. Simulation of binding free
energy and receptor activation. “Molecular dynamics simulations and
experimental site-directed mutagenesis results convincingly demonstrated how
the ligand binds to the receptor.”
Viewpoint: Is there a way to get the young people interested in science?
Sampsa Jaatinen and Petri Salo, Helsinki University of Technology: Multiscale modeling of oxidation. “We have successfully combined different simulation methods on different length scales to study the oxidation of the copper surfaceCombining methods opens new doors to see the dynamics and driving forces behind the observed structures.”

Saara Värttö, CSC: Finns benefit from the European supercomputing resources
Seppo Mustonen: Survo Crossings. “The statistical programming language SURVO 66, and SURVO 76, was one of the first interactive statistical packages, developed some 40 years ago. The various generations of the Survo system have played an essential parti in the tradition of statistical computing in Finland.”
