Through the Human Genome Project, the HapMap Project and other efforts, we are beginning to identify genes that are modified in some diseases. More difficult to measure and identify are the regulatory regions in DNA – the ‘managers’ of genes – that control gene activity and might be important in causing disease.
Today, a team led by the Wellcome Trust Sanger Institute, together with colleagues in the USA and Switzerland, provide a measure of just how important regulatory region variation might be in a pilot study based on some 2% of the human genome. As many as 40 of 374 genes showed alteration in genetic activity that could be related to changes in DNA sequence called SNPs.
“We were amazed at the power of this study to detect associations between SNP variations and gene activity,” commented Dr Manolis Dermitzakis, Investigator, Division of Informatics at the Wellcome Trust Sanger Institute. “We were even more amazed at the number of genes affected: more than 10% of our sample – or perhaps 3000 genes across the genome – could be subject to modification of activity in human populations due to common genetic variations.”

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...
Quantum computers may one day solve algorithmic problems which even the biggest supercomputers today can’t manage. But how do you test a quantum computer to...
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
