After positive evaluation by an international team of experts, the Priority Programme (SPP 1385) “The First Ten Million Years of the Solar System” supported by the German Research Council (DFG) has now embarked on its second funding period with twelve new projects on board.
The investigations of the priority programme revolve crucially around material from small bodies like asteroids and comets, the point being that they have not evolved to the formation of a large planet but have remained at the level of small planets called planetesimals. “This means that they have preserved the unchanged relics of dust and rock composition on the way to larger planetary bodies,” says Prof. Trieloff. In this connection, the scientists are investigating sample material from meteorites and comets as well as interstellar material from which the first small bodies and planetesimals took shape. Isotopic dating is used to define more closely the span of time in which asteroids hundred of kilometres across achieved their present dimensions. In addition, the scientists are looking into the heating and the chemical and physical development of planetesimals.

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
