Now researchers at the Indian Institute of Technology in Delhi have used techniques from information theory to identify DNA introns and exons an order of magnitude faster than previously developed methods.
The researchers were able to achieve this breakthrough in speed by looking at how electrical charges are distributed in the DNA nucleotide bases. This distribution, known as the dipole moment, affects the stability, solubility, melting point, and other physio-chemical properties of DNA that have been used in the past to distinguish exons and introns.
The research team computed the “superinformation,” or a measure of the randomness of the randomness, for the angles of the dipole moments in a sequence of nucleotides. For both double- and single-strand forms of DNA, the superinformation of the introns was significantly higher than for the exons. Scientists can use information about the coding and noncoding regions of DNA to better understand the human genome, potentially helping to predict how cancer and other diseases linked to DNA develop.

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
