As an eyewitness sits on the stand in a courtroom recalling details of an incident, how much of what he or she remembers actually happened?
False memories are a common occurrence in the courtroom and in everyday life, and have long been considered by psychologists as a side effect of efforts to boost memory. New research from Tufts University has answered the question of how to increase memory, without also increasing corresponding false memories.
"The better we understand false memory, the more we will be able to explain the factors that lead to the problem in the laboratory and real world situations," explained Tufts University psychologist Salvatore Soraci, whose research is published in Julys issue of Journal of Experimental Psychology: Learning, Memory and Cognition. "Generative learning holds the promise of immunizing people against the pitfalls of false memory."

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
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...
