A restrictive diet in mice reduces the build-up of a substance linked to memory loss. But can the findngs be applied to humans?
Restricting the diets of mice reduces the build-up of plaques in the brain that are linked to Alzheimers disease, according to a USC study. With obese people generally considered to be at a higher risk for developing Alzheimers, the research raises questions about whether the findings are potentially applicable to humans. "This is the first indication that modest changes in the normal diet can slow some aspects of Alzheimers disease," said Caleb Finch, co-author of the study published in the online version of the journal Neurobiology of Aging. "But that is far and away yet to be proven for humans. Its a big jump to say that whats true for a mouse in a cage is relevant to people living in our complex world," Finch said.
In the study, conducted with collaborators at the University of South Florida in Tampa, researchers used mice whose DNA had been altered with human genes from two families with early onset hereditary Alzheimers. The mice were then split into two groups as young adults: one that could eat all it desired ("ad libitum") and the other that had its food intake reduced by 40 percent over a four-week period (diet- restricted).

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
