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.
The monitoring of antiretroviral treatments by the medical staff affects the health of HIV patients.

Making the most of HIV treatments in Cameroon

A study on the effectiveness of VIH/AIDS treatments in Cameroon, conducted for the first time in urban and rural areas, highlights insufficient treatment success rates. It calls for the enhanced biological monitoring and support of patients by caregivers, including in the hinterland.
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.

Larvae on the menu

According to an FAO report, there will be 9.7 billion human beings on the planet in 2050. Food production must increase by 70% to feed everyone. In this context, insects appear to be a possible source of alternative food. But what is their nutritional value? We focus on that of palm weevil larvae.
The fruit clusters of Coccoloba uvifera give it its nickname of sea grape.

Unwavering symbiosis

Research conducted on the introduction of a tree from extreme environments into the sand dunes of Senegal shows its solid relationship with a fungus. This fungus naturally accompanies the tree from its environment of origin, on the other side of the Atlantic.
