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.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex...
