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).

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
