Manufacturing the core engine of cell division

Scientists are now able to fully reconstitute the engine of the mitosis machinery, called kinetochore. Being able to model a functioning kinetochore is the first step towards the making of artificial chromosomes, that may one day be used to restore missing functions in cells.

Breakthrough for tracking RNA with fluorescence

Researchers have succeeded in developing a method to label mRNA molecules, and thereby follow, in real time, their path through cells, using a microscope - without affecting their properties or subsequent activity. The breakthrough could be of great importance in facilitating the development of new RNA-based medicines.

Biosensors woven into clothing could detect airborne COVID-19

Special biosensors embedded in clothing could detect bacteria and viruses including COVID-19, according to international researchers who say this technology could be used in face masks for primary care workers. The biosensors, which use nucleic acids to detect nasty bugs with high sensitivity and accuracy, are made using freeze-dried, cell-free synthetic CRISPR technology which is flexible enough to be placed into clothing.

Plant biologists solve major cell puzzle on path to leaf engineering

Scientists discovered that tensile force patterns in thin, pressurized cell walls carry information that pattern cell and tissue morphogenesis. The findings uncover a conserved cellular basis of plant growth and are key to understanding leaf architecture and potentially modifying it in the future to improve plants.
