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.

Set of bacterial genes essential for colonising plant roots
Like humans and animals, plants have a microbiota that shapes their health and thanks to which they assimilate nutrients from the soil. How is this microbiota assembled? Using an innovative approach, scientists at the Max Planck Institute and INRAE have discovered three genes essential for bacteria to colonise plants and live in and on plant roots.

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.

An international collaboration identifies new genes influencing beef production
Beef currently accounts for 21% of the world's meat consumption, placing it third after poultry and pork. It therefore plays a crucial role in the global food system, with great economic and cultural importance in many countries. However, its production has a high environmental impact, mainly due to greenhouse gas emissions that contribute to climate change.

Blood of glaciers: how an alga adapts to living in snow
Blood of glaciers: how an alga adapts to living in snow
In the spring, Alpine glaciers sometimes don a sheer red or orangish veil. Known as 'red snow' or 'blood snow', this phenomenon is caused by the blooming of Sanguina nivaloides , a microscopic alga. Scientists from the CNRS, the French Alternative Energies and Atomic Energy Commission (CEA), Météo-France, INRAE, and Université Grenoble Alpes 1 turned their attention to this organism, which forms the pillar of a snowy ecosystem still poorly understood.

'Blood of the glaciers': how an algae adapts to life in the snow
’Blood of the glaciers’: how an algae adapts to life in the snow
In spring, Alpine glaciers sometimes turn a thin layer of red or orange. This phenomenon, known as "glacier blood", is due to the proliferation of a microscopic alga called Sanguina nivaloides . Scientists 1 from CNRS, CEA, Météo-France, INRAE and Grenoble Alpes University have been studying this organism, which forms the backbone of a little-known snow ecosystem.

Antibiotic resistance: a new mechanism observed in real time thanks to innovative microscopy techniques
Antibiotic resistance: a new mechanism observed in real time thanks to innovative microscopy techniques
A better understanding of how bacteria acquire resistance to antibiotics is a key research issue in tackling the major public health problem of antibiotic resistance. The main mechanism by which these resistances are disseminated is called "DNA transfer by bacterial conjugation". Until now, this was thought to occur only between bacteria in direct contact with each other.

A neural organoid with an immune environment
French, Singaporean and British researchers, led by Prof. Florent Ginhoux, head of a research team at Gustave Roussy/Inserm, have succeeded in demonstrating in a neuronal organoid the role of the brain's immune environment in its formation and development. The development of these three-dimensional structures integrating neuronal cells and the immune environment is, to date, one of the most complete in vitro models of the human brain.

New insights into the secret of plant growth
Unlike animals, plants have cells that are all surrounded by a strong wall. This protects them but also encloses them in a rigid skeleton. So how can they grow despite this wall? Scientists from INRAE and the CNRS, in collaboration with Swiss and Belgian teams, have now unlocked part of this secret.

Who were the first modern humans to settle in Europe?
Who were the first modern humans to settle in Europe?
Before modern humans settled definitively in Europe, other human populations left Africa for Europe beginning approximately 60,000 years ago, albeit without settling for the long term. This was due to a major climatic crisis 40,000 years ago, combined with a super-eruption originating from the Phlegraean Fields volcanic area near current-day Naples, subsequently precipitating a decline in ancient European populations.

Asleep but Open to the World: We Can Still Respond to External Stimuli
Asleep but Open to the World: We Can Still Respond to External Stimuli
When we sleep we are not completely cut off from our environment: we are still able to hear and understand words. These observations, resulting from the close collaboration between researchers from Inserm, CNRS, Sorbonne Université and AP-HP at the Brain Institute and the Department of Sleep Disorders at Pitié-Salpêtrière Hospital in Paris, call into question the very definition of sleep and the clinical criteria that distinguish between its different stages.
