Sleeping sickness parasite masters three different swimming modes

https://www.mpg.de/4345915/sleeping_sickness?page=1

The causative agent of African sleeping sickness, annually responsible for several thousands of deaths in Africa and South America, is a motile cell: it propels itself through its host’s bloodstream until – in the last stage of the disease – it overcomes the blood-brain-barrier and penetrates its victim’s brain. In order to fight this deadly disease, scientists are trying to understand the parasite’s exact patterns of movement. Researchers from the Max Planck Institute for Dynamics and Self-Organization (MPIDS) in Germany as well as from the Universities of Würzburg, Göttingen and Basel have now succeeded in identifying three different swimming modes. In addition, they were able to show for the first time, that these swimming modes correspond to the shape and stiffness of the parasite.
What is for sure, however, is that Trypanosoma’s method of moving forward is extremely

Ants employ odors for orientation

The desert ant’s use of its own built-in GPS – consisting of a sun-compass-based path integration system and visual landmarks – in locating its nest is a known phenomenon. Researchers recently ascertained, however, that this system also includes a sense of smell. Even more surprising is the discovery that these animals learn to distinguish between different odors in the nest environment, and use these like a map. Markus Knaden and his team at the Max Planck Institute for Chemical Ecology in Jena set out to search for clues in ant country.
Because Knaden and Steck were not sure whether even one (and if so which) of the

Interview with Susan Trumbore on the future of the Amazon

In the discussion about the climate crisis, there is a lot of talk about tipping points. One example is deforestation in the Amazon. In early August, eight countries in the Amazon met for a summit on the future of the rainforest. In this interview, Susan Trumbore, Director at the Max Planck Institute for Biogeochemistry, uses her research on the ground to explain how realistic a tipping point is in the Amazon ecosystem and whether the Amazon Summit will bring change.
We also cannot be sure which functions – like biodiversity – would be lost forever
