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.
have succeeded in coupling an extremely small quantum dot with 1,000 times larger trumpet-shaped nanowire. The movement of the nanowire can be detected with a sensitivity of 100 femtometers via the wavelength of the light emitted by the quantum dot. Conversely, the oscillation of the nanowire can be influenced by excitation of the quantum dot with a laser.
A research group at the Biozentrum, University of Basel, has developed a new method to measure the half-life of RNA molecules. The study revealed that commonly used methods provide distorted results and that RNA molecules live an average of only two minutes, ten times shorter than previously assumed.
The research team of Prof. Sonja Hofer at the Biozentrum, University of Basel, has discovered why our brain might be so good at perceiving edges and contours. Neurons that respond to different parts of elongated edges are connected and thus exchange information. This can make it easier for the brain to identify contours of objects.
A study by zoologists from Switzerland and the US shows: praying mantises all over the globe also include birds in their diet.
The cell scaffolding holds muscle fibers together and protects them from damage. Individuals who suffer from muscular dystrophy often lack essential components in this cell scaffold. As a result, their muscles lack strength and become progressively weaker. The research team of Prof. Markus Rüegg at the Biozentrum, University of Basel, has now designed two proteins that stabilize the cell scaffolding link it to the muscle fiber and thereby restore muscle structure and function.
It is likely to be one of the oldest prosthetic devices in human history: Together with other experts, Egyptologists from the University of Basel have reexamined an artificial wooden big toe. The find is almost 3000 years old and was discovered in a female burial from the necropolis of Sheikh ´Abd el-Qurna close to Luxor.
Many bacteria are armed with nano-spearguns, which they use to combat unwelcome competitors or knockout host cells. The pathogen responsible for tularemia, a highly virulent infectious disease, uses this weapon to escape from its prison in cells defending the host. Researchers from the Biozentrum of the University of Basel report on this bacterial strategy in the current issue of “Nature Communications”.
Stem cells persist in the adult mammalian brain and generate new neurons throughout life. A research group at the Biozentrum of the University of Basel reports in the current issue of "Science" that long-distance brain connections can target discrete pools of stem cells in their niche and stimulate them to divide and produce specific subtypes of olfactory bulb neurons. This allows the “on-demand” generation of particular types of neurons in the adult brain.
