The inspiration for swarm intelligence algorithms is in the natural world, for example the behaviour of ants. These types of algorithms are used, for example, in management and interest in them continues to grow, says Professor Adam Słowik.
Sparganosis is a parasitic disease, about which little was known in Europe until recently. It turns out, however, that it affects many animal species, it can spread in the environment and pose a threat to humans, report scientists from the Mammal Research Institute PAS in Białowieża, who have been studying the disease for several years.
Plankton, microplastics and mineral crumbs, which are often flat in shape, encounter changes in the density of water layers when sinking in seas or oceans. And then they perform a ‘mysterious’ dance, thanks to which they descend more slowly than previously assumed, shows the researcher from Institute of Geophysics PAS.
Insects that live on corpses not only help forensic entomologists estimate time of death, but may also change the course of the investigation, for example by determining that the body was moved, says Dr. Marcin Kadej, head of the Laboratory of Forensic Biology and Entomology at the University of Warsaw.
In times of starvation, ant workers eat their dead nest mates. And if the corpse is infected with a fungus, they disinfect it with formic acid before consumption - in the case of more severely infected corpses, they apply a higher dose of acid and then leave the corpse in a ‘cemetery’.
