Better Weather Forecasts for Africa: Development Assistance 2.0

Precipitation forecasts are very useful for agricultural areas such as the Sahel. However, while there are reliable models and measurements for Europe, a targeted use of weather information for Africa remains a vision for the future. Scientists from the Karlsruhe Institute of Technology (KIT) and the Heidelberg Institute for Theoretical Studies (HITS) are therefore researching methods to improve precipitation forecasts for Africa.

How black holes shape the cosmos

Astrophysicists from Heidelberg, Garching, and the USA gained new insights into the formation and evolution of galaxies. They calculated how black holes influence the distribution of dark matter, how heavy elements are produced and distributed throughout the cosmos, and where magnetic fields originate. This was possible by developing and programming a new simulation model for the universe, which created the most extensive simulations of this kind to date. First results of the “IllustrisTNG” project have now been published in three articles in the journal Monthly Notices of the Royal Astronomical Society. These findings should help to answer fundamental questions in cosmology.

The largest genome ever: Decoding the Axolotl

A team of researchers led by scientists in Vienna, Dresden and Heidelberg has decoded the entire genetic information of the Mexican salamander axolotl. The axolotl genome, which is the largest genome ever to be sequenced, will be a powerful tool to study the molecular basis for re-growing limbs and other forms of regeneration. The journal NATURE publishes the news in its current issue.

A new genome for regeneration research

The planarian flatworm Schmidtea mediterranea is an extraordinary animal. Even when cut into tiny pieces, each piece can regenerate back into a complete and perfectly proportioned miniature planarian. Key to this ability are fascinating adult stem cells, a single one of which can restore a complete worm. But how Schmidtea mediterranea achieves these feats is so far poorly understood. An important step towards this goal is the first highly contiguous genome assembly of Schmidtea mediterranea that researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Dresden in cooperation with the Heidelberg Institute for Theoretical Studies (HITS) report in the current issue of Nature.

Kerstin Hoppenhaus and Andreas von Bubnoff to be “Journalists in Residence” at HITS

The Heidelberg Institute for Theoretical Studies gives science journalists the opportunity to deepen their knowledge of computer-based, data-driven science with a longer stay at the institute. For the third time, the program was announced internationally. Candidates from six continents applied. The jury chose the science journalists Kerstin Hoppenhaus (Berlin, Germany) for 2018 and Andreas von Bubnoff (New York, USA) for 2019.

Neutron Stars on the Brink of Collapse

Neutron stars are the densest objects in the Universe; however, their exact characteristics remain unknown. Using simulations based on recent observations, a team of scientists including HITS researcher Dr. Andreas Bauswein has managed to narrow down the size of these stars. When a very massive star dies, its core contracts. In a supernova explosion, the…

Tracking down the origins of gold

The European Research Council has awarded HITS astrophysicist Andreas Bauswein an ERC Starting Grant worth approximately 1.5 million euros. Using computer simulations, the aim of the project is to better understand the collisions between neutron stars. These are seen as potential candidates for the formation of heavy elements such as gold, silver and uranium.

Noisy cell membranes

Rapid information transfer is vital for the inner workings of body tissues. With computer simulations, researchers from Colombia and Germany found that mechanical pulses travel through membranes for biologically relevant distances at the speed of sound. The researchers think that membranes could serve as a tin can telephone for the cell.
