Health in Transition

It is no longer rare for inhabitants of the Global South to die from cancer or diabetes. In these regions, non-communicable diseases now cause more deaths than infectious ones. This is due to changing diets and new—more urban and industrialised—lifestyle habits. Populations must also cope with the...

The Challenges of the Sub-Saharan Urban Explosion

Sub-Saharan African cities are presently growing at a size and speed unprecedented in human history. This region of the continent, which was always very rural up to now, is becoming predominantly urban. Small, medium-sized and large cities are doubling in size year on year, with some growing by 1...

Malaria: P. vivax detected in the oasis of Atar

For the first time, the presence of the Plasmodium vivax parasite has been confirmed in Atar, northern Mauritania: it is responsible for most cases of malaria. It is therefore crucial to take every step to avoid an epidemic, not just in Mauritania but also in North Africa, or even beyond, notably in...

Biodiversity of freshwater fish in turmoil

In the last few centuries, 15% of new fish species have been introduced by Man into rivers across the world. Researchers have found that these introductions alter the ecosystem to a much larger extent than originally anticipated.

Onchocerciasis and epilepsy: a strong temporal link

There is a long-running debate within the scientific community as to whether onchocerciasis causes epilepsy. For the first time, a cohort study clearly shows a temporal connection between the two.

Malaria: cracking the genome of P. vivax-like

Research by experts in primates, mosquitoes and malaria parasites sheds light on the emergence of a form of the disease which affects human populations throughout the tropical world. It opens up new avenues for combating this scourge.
Wild form of millet in the Sahara

Genetic diversity in millet: a past and future adaptive advantage

Having sequenced the millet genome, an international consortium involving French researchers from IRD, Indian, Chinese researchers and numerous laboratories from the North and South, studied different wild and cultivated varieties. This allowed them to trace the history of cultivated millet and...
Root nodules of Discaria (Order: Rosales), a non-legume species capable of nitrogen-fixing symbiosis.

Nitrogen-fixing symbioses reveal themselves

Recent research has revealed the origin and evolution of symbiotic relationships between certain plants and soil bacteria in order to use atmospheric nitrogen. This knowledge could ultimately contribute to the development of sustainable agriculture minimising the use of chemical fertilisers.

Protecting mosquitoes to protect humans from malaria

Scientists are researching a vaccine intended to interrupt the life cycle of Plasmodium, the malaria parasite. This original approach, designed to reduce the pressure of the disease on exposed populations, has just been tested in the natural environment of the parasite.
