Shedding new light on the origin of metastases
Shedding new light on the origin of metastases
Research can now target metastases more effectively thanks to a new approach that takes into account the enormous heterogeneity and phenotypes of tumour cells, with a team from the University of Geneva pinpointing a gene that prevents their development. Before an effective treatment can be devised, we have to be able to understand the specific effect of an anti-cancer substance on the cell type, or even the cell, that produces metastases in the enormous cellular heterogeneity of tumours.

Pesticide Exposure Associated with Headaches in Children
Pesticide Exposure Associated with Headaches in Children
Children living in agricultural areas are likely to be exposed to a variety of pesticides during their daily lives, which may impair their neurodevelopment. The most vulnerable populations are families and farmworkers in lowand middle-income countries. In a study published in Environment International by Swiss TPH and partners at the University of Cape Town, researchers found that children in South Africa who engage in pesticide-related farm activities often have more headaches and possibly lower cognitive performance.

Host Genetic Factors Shape Composition of Virus Communities
Host Genetic Factors Shape Composition of Virus Communities
Plants can be infected by multiple viruses at once. However, the composition of the pathogen community varies, even if individuals belong to the same species and the same population. Ecologists at the University of Zurich have now shown that these differences are primarily due to genetic variation among the hosts.

Shortcuts lead to greater pesticide contamination
Shortcuts lead to greater pesticide contamination
In agricultural areas, large volumes of water from fields, roads and paths drain directly into streams via manholes and other forms of artificial drainage. These shortcuts also transport pesticides into surface waters - and, according to a new study, in significantly larger quantities than was previously assumed.
