Researchers at the University of Dundee have made a significant new discovery on how cells behave and protect themselves against cancers and congenital disorders as reported in Nature tomorrow (Thursday April 21).
Dr Tomo Tanaka and his team members at the University’s School of Life Sciences, Drs Kozo Tanaka, Naomi Mukae and Hilary Dewar, in collaboration with Drs Euan James and Alan Prescott and researchers in Germany, have uncovered how cells prepare for the process of chromosome separation.
All human cells, except eggs and sperms, contain 46 chromosomes, all of which carry vital genetic information. Because genetic information is crucial for the proper function of cells for the organs and tissues that they organise, all chromosomes must be precisely copied and separated into two cells, known as the daughter cells, during each cell division. Otherwise cells would die, become transformed into cancer cells, or cause congenital diseases such as Downs syndrome.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
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...
