How viruses move through insects for transmission of diseases
Viruses are master parasites that have adapted to infect many host species. Some viruses even use multiple hosts to spread their infections—such as arboviruses that use insects to move their infections to mammalian hosts like humans. Understanding.....»»
A roadmap for using viruses to enhance crop performance
Humans, livestock and companion animals benefit from virus-based vaccines and gene therapies, but crops do not. This paradox is highlighted by an international research group led by the Institute of Molecular and Cellular Biology of Plants (IBMCP) wi.....»»

Illuminating the unavoidable imperfections of nanostructures
A new study by a collaborative team from the University of Twente and the e-Science Center in Amsterdam compares the transmission of light through a utopian model with a real 3D nanostructure. These nanostructures are integral to our daily technologi.....»»
Avian flu has infected dairy cows in more than a dozen states—a microbiologist explains how the virus is spreading
The current strain of avian flu, H5N1, is responsible for the culling of millions of domestic birds and has sickened more than a dozen farmworkers in 2024, most recently in Colorado......»»
Study reveals isolation, endogamy and pathogens in early medieval Spanish community

Mapping the sex life of malaria parasites at single cell resolution reveals genetics underlying transmission
Malaria is caused by a eukaryotic microbe of the Plasmodium genus, and is responsible for more deaths than all other parasitic diseases combined. In order to transmit from the human host to the mosquito vector, the parasite has to differentiate into.....»»
