The cartography of the nucleus

Nestled deep in each of your cells is what seems like a magic trick: Six feet of DNA is packaged into a tiny space 50 times smaller than the width of a human hair. Like a long, thin string of genetic spaghetti, this DNA blueprint ...

Cas3: a biological fishing rod and a shredder rolled into one

CRISPR-Cas9 has made gene editing a lot easier, and will eventually contribute to elimination of hereditary diseases from our DNA. But despite the fact that researchers use CRISPR-Cas9 and similar bacterial immune systems ...

Does physical activity influence the health of future offspring?

Physical and mental exercise can affect the learning ability of future offspring, at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate ...

Biomimetic chemistry—DNA mimic outwits viral enzyme

Not only can synthetic molecules mimic the structures of their biological models, they can also take on their functions and may even successfully compete with them, as an artificial DNA sequence designed by Ludwig-Maximilians-Universitaet ...

A more sensitive device for characterizing DNA in blood circulation

Developed and patented in 2012 and 2014 in the Laboratoire d'Analyse et d'Architecture des Systèmes (LAAS-CNRS) and implemented industrially by Picometrics-Technologies, BIABooster technology characterizes DNA with new precision ...

Using gold particles to make the invisible visible

Gold nanoparticles give us a better understanding of enzymes and other molecules. Biswajit Pradhan, Ph.D. candidate at the Leiden Institute of Physics, uses gold nanorods to study individual molecules that would be challenging ...
