Surprising role of female sex pheromone in crop pest: new biocontrol possibilities?
INRAE researchers have discovered that female pheromones play a remarkable role in the African cotton moth. In general, these pheromones trigger mate attraction, promoting encounters between males and females during reproductive periods. Astonishingly, the African cotton moth possesses a pheromonal compound whose modulatory effects exceed those of light itself, a discovery that can inform future biocontrol strategies.

Amyotrophic lateral sclerosis: a new avenue for improving patient diagnosis and follow-up
Amyotrophic lateral sclerosis: a new avenue for improving patient diagnosis and follow-up
Amyotrophic lateral sclerosis or Charcot's disease is a neurodegenerative disease that results in progressive paralysis and subsequent death. Diagnosing it is difficult and no curative treatment exists to date, making these challenges for research. In a new study, Inserm researcher Caroline Rouaux and her team at the Strasbourg Biomedical Research Centre (Inserm-Université de Strasbourg), in collaboration with researchers from Ludwig Maximilian University in Munich, CNRS and Sorbonne Université, show that electroencephalography could become a diagnostic and prognostic tool for the disease.

The brain mechanisms behind our desire to dance
Why does some music make us want to dance more than others? This is the question that a research team from Inserm and Aix-Marseille Université tried to answer by studying the desire to dance (also called the 'groove') and the brain activity of 30 participants who were asked to listen to music. Their findings show that the groove sensation is highest for a moderately complex rhythm and that the desire to move is reflected in the brain by an anticipation of the music's rhythm.

Back to the future: not all grape varieties succumbed to the extreme heat wave of 2019
Heat waves are increasingly common worldwide, making it necessary to adapt our crops. A new study by INRAE and Institut Agro, based on an experiment conducted during an unprecedented heatwave in France in June 2019, has uncovered regions of grapevine genome associated with extreme heat tolerance. The results were published on 7 February in New Phytologist.

HIV: early treatment, one key to remission
HIV: early treatment, one key to remission
People living with HIV need to take antiretroviral treatment for life to prevent the virus from multiplying in their body. But some people, known as "post-treatment controllers,- have been able to discontinue their treatment while maintaining an undetectable viral load for several years. Starting treatment early could promote long-term control of the virus if treatment is discontinued.

Ancestors of primates lived in pairs
Ancestors of primates lived in pairs
A study carried out by CNRS 1  scientists working with an international team has revealed that around 70 million years ago, when dinosaurs existed, the ancestors of primates most commonly lived in pairs. Only 15% of them opted for a solitary lifestyle. This discovery - that our ancestors adopted variable forms of social organization - challenges the hitherto commonly accepted hypothesis that at the time of dinosaurs, the ancestors of primates lived alone, and that pair living evolved much later.

Wildflowers increasingly doing without insect pollinators
Wildflowers increasingly doing without insect pollinators
Scientists at the CNRS and the University of Montpellier 1 have discovered that flowering plants growing in farmland are increasingly doing without insect pollinators. As reproduction becomes more difficult for them in an environment depleted in pollinating insects, the plants are evolving towards self-fertilisation.

Discovery of the role of a brain regulator involved in psychiatric illnesses
Contrary to all expectations, GluD1 - a receptor considered to be excitatory - has been shown in the brain to play a major role in controlling neuron inhibition. Given that alterations in the GluD1 gene are encountered in a certain number of neurodevelopmental and psychiatric disorders, such as autism (ASD) and schizophrenia, this discovery opens up new therapeutic avenues to combat the imbalances between excitatory and inhibitory neurotransmissions associated with these disorders.
