In the nearest future we may witness global cooling in spite of increasing concentration of greenhouse gases in the atmosphere. That can happen, if the following hypothesis is correct: not the growth of greenhouse gases concentration provokes temperature to rise, but vice versa.
It is generally believed nowadays that greenhouse gases are responsible for the growth of temperature of the atmosphere, but that might be wrong. Recent climate change is similar to those regularly developed in the past of our planet. Studies conducted at the research station "Vostok" revealed that for the last 100 thousand years an increase in temperature always preceded the growth of greenhouse gases concentration, but not inversely. When temperature began to decrease, the concentration of gases continued to grow for a period of 2-3 thousand years.
Russian scientists have analyzed changes occurred within the past 5, 20, and 100 thousand years and established that each warming is associated with the same behaviour of greenhouse gases: temperature rises firstly, and the concentration of greenhouse gases begins to increase later, with a lag of several thousand years. The growth of gases concentration is faster than that of temperature and soon outruns the latter. With a turn from warming to the next phase of cooling, the concentration of greenhouse gases inertially grows for a while. Then their concentration begins to decrease, which soon gets faster than the temperature decrease. This tendency progresses until glaciation phase that closes each climatic cycle.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
