A virus that infected animals hundreds of millions of years ago has become essential for the development of the embryo
All animals have evolved thanks to the fact that certain viruses infected primitive organisms hundreds of millions of years ago. Viral genetic material was integrated into the genome of the first multi-cellular beings and is still in our DNA today......»»
Ants help reveal why sourcing different plants for eco fuels is crucial for biodiversity
Despite being a renewable energy source, the use of biofuel is controversial, as growing few, highly productive crops for fuel can lead to biodiversity loss in the cropping systems where biomass is produced. A cropping system refers to the crops, the.....»»
Invasive ants selectively abandon toxic baits, evading our most effective eradication method
