Measuring forces in the DNA molecule
DNA, our genetic material, normally
has the structure of a twisted rope ladder. Experts call this structure a
double helix. Among other things, it is stabilized by stacking forces between
base pairs. Scientists have now succeeded at measuring these forces for the
very first time on the level of single base pairs. This new knowledge could
help to construct precise molecular machines out of DNA.
How the brain builds panoramic memory
Two brain regions that are involved
in creating panoramic memories have now been identified by neuroscientists.
These brain regions, known as the OPA and RSC, help us to merge fleeting views
of our surroundings into a seamless, 360-degree panorama.
