Genome-editing 'toolbox' targets multiple genes at once
Scientists have designed a system to modify, or edit, multiple genes in the genome simultaneously, while also minimizing unintended effects. The gene-editing 'toolbox' provides a user-friendly solution that scientists can apply to research on cancer and other disciplines, the researchers said.

How animals keep their cells identical
A regulatory protein named ERI-1 helps ensure that all cells in a tissue remain identical to one another, a research team has discovered for the first time. The work involved an unusual collaboration between developmental biologists and linguists, with the latter contributing their expertise with machine learning software. The finding could bring biologists one step closer to understanding some cancers and other age-related diseases.

Plasma technology can be tapped to kill biofilms on perishable fruit, foods
Seeing fruit 'turn bad and going to waste' inspired a team of researchers in China to explore using atmospheric pressure nonequilibrium plasma as a novel solution to extend the shelf life of fruit and other perishable foods. Now their computational study of how air plasma interacts with bacterial biofilms on an apple's surface suggests that plasma technology could be used to decontaminate food in the future.

Plant compounds give '1-2' punch to colon cancer
A preliminary cell study finds combining curcumin, the active ingredient in spicy curry dishes, and silymarin, a component of milk thistle, inhibited the spread of colon cancer cells and increased cancer cell death.
