Screening for genes to improve protein production in yeast

By silencing genes, researchers have managed to increase protein production in yeast significantly. This method can lay the grounds for engineering better yeast production hosts for industries producing biopharmaceutical ...

Humans no longer have ancient defence mechanism against viruses

Insects and plants have an important ancient defence mechanism that helps them to fight viruses. This is encoded in their DNA. Scientists have long assumed that vertebrates - including humans - also had this same mechanism. ...

Mammals defend against viruses differently than invertebrates

Biologists have long wondered if mammals share the elegant system used by insects, bacteria and other invertebrates to defend against viral infection. Two back-to-back studies in the journal Science last year said the answer ...
