Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. However, Rubisco performs this reaction slowly and can also have unwanted reactions with oxygen. Algae have figured out a clever way to increase the efficiency of carbon ...
Chemist Prof. Peter H. Seeberger and chemical engineer Prof. Andreas Seidel-Morgenstern have been selected as the inaugural "Humanity in Science" prize winners. Seeberger – director at the Max Planck Institute of Colloids and Interfaces and professor at the Freie Universität Berlin and ...
Small changes in the composition of green leaf volatiles induced by herbivory guide ovipositing female moths to unattacked plants
Researchers at the Max Planck Institute for Chemical Ecology, Jena, Germany, discovered that the ability of Manduca sexta moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less ...
Researchers found that adult wild chimpanzees have developed a certain immunity against malaria parasites
Wild great apes are widely infected with malaria parasites. Yet, nothing is known about the biology of these infections in the wild. Using faecal samples collected from wild chimpanzees, an international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig ...
Rodents move their eyes in opposite directions, thereby always keeping an eye on the airspace above them
Scientists from the Max Planck Institute for Biological Cybernetics in Tübingen, using miniaturised high-speed cameras and high-speed behavioural tracking, discovered that rats move their eyes in opposite directions in both the horizontal and the vertical plane when running around. Each eye moves ...
A new study examines how individuality develops
How do organisms evolve into individuals that are distinguished from others by their own personal brain structure and behaviour? Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they were able ...
Computer simulation shows that the reduction of natural dental wear might be the main cause for widely spread non-carius cervical lesions in our teeth
Scientists of the Max Planck Institute for Evolutionary Anthropology in Leipzig and the Senckenberg Research Institute in Frankfurt together with dental technicians have digitally analysed modern human teeth using an engineering approach, finite element method, to evaluate the biomechanical ...
Researchers in Freiburg identify a protein responsible for the correct arrangement of the chromosome centromeres in the nucleus
Two metres of DNA are packed into the cell nucleus, presumably based on a strictly defined arrangement. Researchers working with biologist Patrick Heun from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded in explaining a phenomenon, which was first ...
Microbes use a channel protein as a syringe for toxins
The bacterium Photorhabdus luminescens is a constant companion of some roundworms. These worms assault insect larvae, thereby infecting them with the bacteria; the pathogens then attack the cells of their victims with a deadly cocktail of various toxins. Scientists at the Max Planck Institute of ...
Insect odorant receptors regulate their own sensitivity
Highly developed antennae containing different types of olfactory receptors allow insects to use minute amounts of odors for orientation towards resources like food, oviposition sites or mates. Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have now used mutant ...
