Two specific areas in chromosome 7 and chromosome 16 have been associated with photosensitivity, an epilepsy-related trait, by a team of European scientists in the January issue of Human Molecular Genetics. Photosensitivity or photoparoxysmal response (PPR) is associated with the most common epilepsy of genetic origin –Idiopathic Generalised Epilepsy (IGE) - and comprehension of the genetics behind it is important to a better understanding of IGE and epilepsy in general.
Epilepsies are a group of brain disorders characterised by recurrent seizures. The disease results from the fact that the neurons (brain cells) of epileptic patients seem to be incapable of properly conduct the nervous signal. This inability leads to excessive and disordered electric activity in the patients’ brain, which can lead to seizures. Seizures trigger involuntary muscle movements and can have a multitude of effects such as altered sensations, changes in awareness, behaviour, movement and/or body function.
Epilepsy affects about 2% of the world population and can create problems in the simplest of everyday activities such as driving, attending a job, school or even staying home alone what has important economic implications for society. Additionally, due to the unpredictability of the seizures that creates a life of constant fear for patients, there is also a extremely high social toll for both patients and their families.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
