Using machine learning to guide and enhance bioengineering
The Automated Recommendation Tool (ART) uses machine learning to accelerate the development of cells for specified goals, eg, bioprocessing and bioproduction.
news
CRISPR editing can result in whole chromosome elimination, say scientists
In a new study, scientists identify some of the pitfalls when using CRISPR Cas9 to correct mutations in human embryos, such as the destruction of whole chromosomes.

Novel vaccine protects mice from lung, bowel and pancreatic cancer
By targeting the mutated KRAS gene, researchers have developed an experimental vaccine that protected mice against a range of cancers.
news
SARS-CoV-2 also uses neuropilin-1 to infect human cells
Researchers reveal that SARS-CoV-2 is more infectious than SARS-CoV because it can use both ACE2 and neuropilin-1 to infect cells.

Could GPCRs be causing people to respond differently to the same drug?
Hannah Balfour explores how genetic variation in G-protein-coupled receptors (GPCRs) and the proteins that regulate the duration of G protein signalling could be contributing to disease and people’s divergent responses to the same therapeutics.
