Flowers' origins remain a mystery

Flowers are the most common type of plant, but scientists have not yet determined how they first evolved. Researchers at CNRS are working to uncover the origins of all life forms, including the emergence of flowering plants.

Invasive species spread with human help

Species like the tiger mosquito, collar macaw, Asian hornet, and electric ant are found in areas far from where they originally lived. Human activities, such as trade and travel, have unintentionally helped these species move to new environments.

Wild boars enter Bordeaux city

Wild boars are increasingly being seen near the city of Bordeaux. Their presence has raised concerns among residents, caused property damage, and sparked political discussions about how to manage the situation.

Zooplankton's role in ecosystems

Small crustaceans and gelatinous organisms, known as zooplankton and microzooplankton, are essential for the survival of many ecosystems. However, much about these tiny creatures is still unknown, and they are threatened by climate change.

Art from microscopic cell images

At the Orsay Museum, scientists have used images of cells seen under a microscope to create a performance. This innovative project blends science with art, offering a new way to visualize microscopic life.

Algae help reduce fungicide use

In Brittany, extracts from algae are being used to decrease the need for fungicides in agriculture. This natural approach not only reduces chemical use but also increases crop yields.

Desert ants navigate without pheromones

Unlike garden ants, which rely on pheromone trails to find their way, desert ants use different mechanisms to navigate. Scientists are studying how these ants manage to find their way without chemical signals.

Life sciences and the origin of shapes

The third episode of Puits de science explores whether life sciences alone can explain the shapes of living beings. The episode also discusses other fields that contribute to this complex question.

Termite queen's longevity studied

The queen of a termite colony can live for up to 40 years, which is much longer than other members of the colony. Researchers are trying to understand the biological reasons behind her extended lifespan.

Simulated forest evolution

Scientists have created simulations showing how forests evolve over thousands of years. These models help explain how factors like wind resistance influence the development of ecosystems over time.

Moving mangroves in Guyana

In Guyana, unique mangrove forests are constantly shifting along the coastline. These mangroves grow extremely fast and form long banks of mud, adapting to their environment in a remarkable way.
