Gut microbial development could be restored in C-section infants by fecal microbiota transplant

The human gut contains a diverse ecosystem of microbes: mainly bacteria, as well as viruses and fungi, termed the gut microbiota.

Researchers map genetic networks controlling human regulatory T cell identity

Unlike most T cells, which launch immune responses against foreign molecules, regulatory T cells are the peacekeepers of the human immune system, damping down inflammatory reactions when they're not needed.

Making healthy, environmentally friendly protein from the air

Increasing environmental challenges have led scientists to rethink how protein can be produced. Traditional processes require a lot of space on land or sea, resulting in a high carbon footprint and reduced resources.

Study shows how climate change may affect different ecosystems

To understand how climate change may affect different ecosystems, 27 researchers from Brazil, Argentina, Colombia, Costa Rica, French Guiana and Puerto Rico, among other countries, conducted experiments in seven different locations involving the aquatic environment in the tank (centrally-located water-holding cup) of bromeliads, a habitat for insect larvae and other small organisms.

Scientists uncover new pathway to protect plants from fungal infection

Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. This discovery was made by scientists from Martin Luther University Halle-Wittenberg (MLU) and the University of the State of Paraná in Brazil.
