AI tailors artificial DNA for future drug development

With the help of an AI, researchers at Chalmers University of Technology, Sweden, have succeeded in designing synthetic DNA that controls the cells' protein production. The technology can contribute to the development and ...

New research shows how octopuses may have evolved

A new paper in Genome Biology and Evolution indicates that a type of octopus appears to have evolved independently to develop something resembling a shell, despite having lost the genetic code that produced actual shells ...

Herbicide resistance no longer a black box for scientists

When agricultural weeds evolve resistance to herbicides, they do it in one of two ways. In target-site resistance, a tiny mutation in the plant's genetic code means the chemical no longer fits in the protein it's designed ...

Researchers improve efficiency and accessibility of CRISPR

One of the most powerful tools available to biologists these days is CRISPR-Cas9, a combination of specialized RNA and protein that acts like a molecular scalpel, allowing researchers to precisely slice and dice pieces of ...

How nitrate regulates gene expression in legumes

Plants in the bean family (legumes) form nodules on their roots to take up nitrogen. Legumes will stop nodule production when nitrogen is plentiful (Figure 1), but precisely how nitrate presence controls nodule formation ...

Nanobodies could help CRISPR turn genes on and off

The genetic tool CRISPR has been likened to molecular scissors for its ability to snip out and replace genetic code within DNA. But CRISPR has a capability that could make it useful beyond genetic repairs. "CRISPR can precisely ...
