Chinese bioengineers have developed a tool called smACGmax, which can simultaneously replace three types of nucleotides in DNA to accelerate the process of directed genome evolution. This technology enables the creation of cells with new beneficial properties and speeds up the development of medicines.
A new study has shown that the T-cell receptor remains closed until it encounters an antigen, rather than always being open as previously believed. This discovery could help improve immunotherapy and vaccine development.
Scientists have discovered a molecular switch that enables plants to enter into symbiosis with nitrogen-fixing bacteria. This breakthrough could pave the way for the development of cereal crops capable of supplying themselves with nitrogen, thereby reducing agriculture's reliance on fertilizers.
