Expert discusses alternatives to pesticides

A researcher at the University of Arizona has discovered compounds derived from Photorhabdus, an insect pathogenic bacterium, that have antimicrobial and nematicidal properties that can potentially replace chemical pesticides.

Turning silenced cancer genes back into fighters

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the ...

Researchers explain signals of CpG 'traffic lights' in DNA

A research team featuring bioinformaticians from the Moscow Institute of Physics and Technology (MIPT) has identified reliable markers of gene activity. The discovery has potential for future applications in clinical practice. ...

Scientists crack the code to regenerate plant tissues

Plant regeneration can occur via formation of a mass of pluripotent cells. The process of acquisition of pluripotency involves silencing of genes to remove original tissue memory and priming for activation by external input. ...

Watching molecules split in real time

Using a new X-ray technique, a team of researchers was able to watch in real time as a molecule split apart into two new molecules. The method could be used to look at chemical reactions that other techniques can't catch, ...
