Individuals with autism have been shown to have a difficult time recognizing faces, but two University of Washington researchers now suggest that the problem may be due to a lack of practice, rather than to abnormal functioning of the affected region of the brain.
Previous research, using an electroencephalogram (EEG) to measure brain activity, had shown that autistic 3- and 4-year-olds failed to show normal brain response when viewing their mothers picture. However, a recent study released at the AAAS (Triple-A-S) Annual Meeting indicates that with time, a mothers image does activate the part of the temporal lobe implicated in face recognition, even when an unfamiliar face does not. AAAS is the American Association for the Advancement of Science.
"These results suggest that lack of normal activation of the fusiform gyrus in persons with autism may be due to their lack of familiarity and experience with faces rather than an inherent problem with the fusiform," said Geraldine Dawson, who directs the University of Washington Autism Center and who was among the first researchers to suggest that an impairment in face recognition might be one of the earliest signs of autism.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
