In a study of more than 2,500 patients, Daniel Vinson, professor of community and family medicine, found that patients who reported feeling sleepy were, surprisingly, less likely to be injured. Patients who reported better sleep quality in the previous seven days also were less likely to be injured, but patients who reported getting more sleep in the 24 hours before an injury than they did in the previous 24 hours were found to have a higher risk of injury.
"It could be that people who feel sleepy change their behavior," Vinson said. "If I'm feeling really tired, maybe I'll stop driving, maybe I won't play sports. If we're changing what we're doing when we're feeling tired, that may be what lowers our risk of injury."
Vinson interviewed injured patients and compared them to a separate control group who were matched by age, sex, location of the injury and time of the injury. Patients were asked about their sleepiness at the time of injury (whether they were tired, sleepy or drowsy). Patients and participants also were asked about their usual quality and quantity of that sleep. Patients were then asked the number of hours they slept in the 24 and 48 hours prior to the injury.
"This doesn't mean that people should go driving when they're feeling tired," Vinson said. "Rather, it suggests that further research needs to be done. It's important for the public's safety that we understand the connection between sleep and injuries."

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...
