A novel formulation of multiple amino acids hinders the replication of Zika virus by up to 90% in human and non-human primate cells, a new study[1] indicates. Researchers tested a unique composition of three free-form amino acids (FFAAP) — cystine, glycine, and glutamate, as well as a minute amount of selenium — that was previously… Read more

An existing technique has been adapted to study the melting behaviour of proteins so that it can be used for the study of bacteria. Thermal proteome profiling (TPP) was developed in 2014 (Savitski et al., Science 2014) and enables scientists to compare the melting behavior of all proteins in a cell or organism before and… Read more

The emotion disgust has long been recognized as having evolved to help our ancestors fend off infection. Now, researchers have been able to show the human disgust system is likely to be structured around the people, practices and objects that pose disease risk. This is the first time researchers have used the perspective of disease… Read more

When a person becomes infected with toxoplasma — for example, by eating insufficiently cooked meat, or by contact with cat… Read more
