Researchers in Egypt have developed a technique to compress DNA sequences of the kind used in medical research so that they take up a lot less space in a computer database but without loss of information. The approach is described in detail in a forthcoming issue of the International Journal of Bioinformatics Research and Applications.

Good news for heterogeneous catalysis and the hydrogen economy: computers can now be used to make accurate predictions of the reactions of (hydrogen) molecules with surfaces. An international team of researchers, headed by Leiden theoretical chemist Geert-Jan Kroes, published on this subject this week in the journal Science.
Hydrogen on copper
The team developed a new method [...]

Researchers at the Kavli Institute for Nanosciences at Delft University of Technology, have succeeded in getting hold of the environment of a quantum particle. This allows them to exercise greater control over a single electron, and brings the team of researchers, led by Vidi winner and FOM workgroup leader Lieven Vandersypen, a step closer still [...]

Clicking and scrolling interrupt our attentional focus. Turning and touching the pages instead of clicking on the screen influence our ability for experience and attention. The physical manipulations we have to do with a computer, not related to the reading itself, disturb our mental appreciation, says associate professor Anne Mangen at the Center for Reading [...]
