Enzymatic DNA synthesis sees the light

According to current estimates, the amount of data produced by humans and machines is rising at an exponential rate, with the digital universe doubling in size every two years. Very likely, the magnetic and optical data-storage ...

Secure nano-carrier delivers medications directly to cells

Medications often have unwanted side-effects. One reason is that they reach not only the unhealthy cells for which they are intended, but also reach and have an impact on healthy cells. Researchers at the Technical University ...

Locating and severing lethal links in DNA

Chemical lesions in the genetic material DNA can have catastrophic consequences for cells, and even for the organism concerned. This explains why the efficient identification and rapid repair of DNA damage is vital for survival. ...

Shedding light on rapid emergence of new species

New international research led by Monash University scientists has changed our understanding of the evolutionary processes that can lead to the rapid emergence of new species.

Barcoding long DNA quantifies CRISPR effects

Current sequencing techniques lack the sensitivity to detect rare gene mutations in a pool of cells, which is particularly important, for example, in early cancer detection. Now, scientists at KAUST have developed an approach, ...

Origins of life: Chemical evolution in a tiny Gulf Stream

Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists at Ludwig-Maximilians Universitaet (LMU) in Munich now report on ...

Molecular forces: The surprising stretching behavior of DNA

When large forces act on a heavy beam, for example, in bridge construction, the beam will be slightly deformed. Calculating the relationship between forces, internal stresses and deformations is one of the standard tasks ...
