During archaeological excavations in the Schöningen open-cast coal mine in 1994, the discovery of the oldest, remarkably well-preserved hunting weapons known to humanity caused an international sensation. Spears and a double-pointed throwing stick were found lying between animal bones about ten meters below the surface in deposits at a former lakeshore. In the years that followed, extensive excavations have gradually yielded numerous wooden…

The next stratospheric flight of the balloon-borne solar observatory Sunrise III is planned for early summer this year. Today's departure of the flight hardware from the Max Planck Institute for Solar System Research (MPS) in Germany to the launch site beyond the Arctic Circle marks the beginning of the final and decisive phase of the mission. On site at the Swedish Space Agency's Esrange Space Center near the city of Kiruna, the Sunrise team…

The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings with contribution from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) and the Weizmann Institute of Science gave rise to a model predicting cellular behavior. Such universal principles now allow a better understanding of the migration of immune and cancer…

As people get older, they increasingly focus on their more important relationships, often turning to family and close friends. This active reorientation towards a few, particularly close relationships could explain why ageing humans live in ever smaller social networks. Since human behavior not only reflects the current conditions of our modern society, but is also the result of our evolutionary past, studies on social aging in our closest…

In wind-tunnel tests, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has investigated the lift generated by commercial aircraft using state-of-the-art measurement and simulation technologies. The findings will help to predict the characteristics of future aircraft much more accurately than before, in order to make them quieter, more efficient and more environmentally friendly. The development of a new aircraft is a…

The amount of power a microswimmer needs to move can now be determined more easily. Scientists from the department Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) developed a general theorem to calculate the minimal energy required for propulsion. These insights allow a profound understanding for practical applications, such as targeted transport of molecules and substrates. One of the most important…

Mining brings huge social and environmental change to communities: landscapes, livelihoods and the social fabric evolve alongside the industry. But what happens when the mines close? What problems face communities that lose their main employer and the very core of their identity and social networks? A research fellow at the University of Göttingen provides recommendations for governments to successfully navigate mining communities through their…

As a result of vaccination or infection, our immune system produces antibodies that attach to the spike protein of SARS-CoV-2, preventing the virus from entering and replicating within cells. In response, the virus develops mutations that cause antibodies to bind less effectively to the spike protein. Since May 2023, the EG.5 lineage of SARS-CoV-2, known as Eris, has been spreading globally and was classified as a "Variant of Interest" by the…

Wie stellen die Kraftwerke der Zelle Proteine her?
