Researchers develop a 'stretching rack' for cells

The behavior of cells is controlled by their environment. Besides biological factors or chemical substances, physical forces such as pressure or tension are also involved. Researchers from Karlsruhe Institute of Technology ...

Chemists make cellular forces visible at the molecular scale

Scientists have developed a new technique using tools made of luminescent DNA, lit up like fireflies, to visualize the mechanical forces of cells at the molecular level. Nature Methods published the work, led by chemists ...

E. coli bacteria offer path to improving photosynthesis

Cornell University scientists have engineered a key plant enzyme and introduced it in Escherichia coli bacteria in order to create an optimal experimental environment for studying how to speed up photosynthesis, a holy grail ...

Embryos taking shape via buckling

The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.). According to a hypothesis ...

New gene regulation model provides insight into brain development

In every cell, RNA-binding proteins (RBPs) help tune gene expression and control biological processes by binding to RNA sequences. Researchers often assume that individual RBPs latch tightly to just one RNA sequence. For ...

Physicists nudge atoms within less than a trillionth of a second

Scientists from Regensburg and Zurich have found a fascinating way to push an atom with controlled forces so quickly that they can choreograph the motion of a single molecule within less than a trillionth of a second. The ...
