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 ...

Understanding what drives cell typing

Scientists know that developing cells in a healthy embryo will transform into a variety of cell types that will make up the different organ systems in the human body, a process known as cell differentiation. But they don't ...

Scientists discover a new gene regulation mechanism

A team of scientists from Russia studied the role of double-stranded fragments of the maturing RNA and showed that the interaction between distant parts of the RNA can regulate gene expression. The research was published ...

New-found molecular signature keeps key genes ready for action

During development, scores of molecular signals prod cells to take on specialized identities and functions. In response to some of these signals, the cellular machinery awakens specific genes called 'immediate early genes' ...

Genes for face shape identified

Genes that determine the shape of a person's facial profile have been discovered by a UCL-led research team.

Antibiotic resistance may spread even more easily than expected

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic ...
