Molecular biologists, developmental biologists and computer scientists at the Universtity of Helsinki, Finland, came together to advance towards cracking the code for how gene expression is controlled. The results of this work were published in Cell, in January 2006.
A genome milestone was reached in 2001 when sequencing of the human genome was completed. This has been followed by complete chemical read-outs of DNA sequence for several species, for example mouse, dog, cow and chicken, in the recent years. But without a code or grammar to reveal the message behind the sequence, the genomic DNA is merely a list of millions and millions of base pairs, A’s, C’s, G’s and T’s one after the other.
Based on the universal code by which DNA encodes amino acids, we can make sense of the constantly increasing amout of DNA sequence data as far as it encodes proteins. This code was solved in 1966 and it has allowed researchers to find new genes and estimate the total number of genes in the human genome. However, coding sequence covers only about 1.2% of the human genome. New codes and grammatical rules need to be resolved in order to understand the remaining 98.8% of the genome.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
