Spiders start out social but later turn aggressive after dispersing and becoming solitary, according to a study publishing July 2 in the open-access journal PLOS Biology by Raphael Jeanson (CRCA-CBI Toulouse) of the National Centre for Scientific Research (CNRS) in France, and colleagues.
Honeybees are well-known for their remarkable cognitive abilities. They rely on their learning capacities to better identify the most profitable flowers. Beyond classical associative learning faculties, the bees were shown to possess an unexpected sense for number. As an example, they can sort numbers in a linear scale including a concept of zero as the lowest quantity.
A recent study, led by Bruno GUIARD, provides experimental evidence that metformin, an oral anti diabetic, produces anxiolytic and antidepressant-like effects in insulin-resistant mice.
In 2016, CNRS scientists demonstrated that the slime mould Physarum polycephalum, a single-cell organism without a nervous system, could learn to no longer fear a harmless but aversive substance and could transmit this knowledge to a fellow slime mould. In a new study, a team from CNRS and the Université Toulouse III – Paul Sabatier has shown what might support this memory and in fact it could be the aversive substance itself! These results were published in a special issue of the Philosophical Transaction of the Royal Society B on 22 April 2019.
The CRCA is proud to announce that Martin Giurfa has been awarded an ERC Advanced Grant for his project : Cognition in an Insect Brain "COGNIBRAINS".
Termite nests have been widely studied as effective examples for ventilation and thermoregulation.
Each year, the CNRS celebrates researchers, engineers and technicians who make an exceptional contribution to the institution's dynamism and reputation.
Thibault Dubois (CRCA) beneficits from a PhD grant from the University Toulouse III- Paul Sabatier and a scholarship from the Macquarie University to study the “Impact of bee spatial strategies on colony dynamics”.
Audrey Dussutour and researchers from the Uppsala university (Sweden) demonstrated that even among unicellulars, there is a wide variety of behaviour in the ability to make good decisions.
Researchers from the CNRS and université Toulouse III – Paul Sabatier (UT3), including Guillaume Isabel from the CRCA, show that fruit flies possess all of the cognitive capacities needed to culturally transmit their sexual preferences across generations.
