The ‘ultimate discovery tool’ for nanoparticles

Similar to what gene chips offer biology; could test billions of different nanoparticles at one time

June 24, 2016

A combinatorial library of polyelemental nanoparticles was developed using Dip-Pen Nanolithography, opening up a new field of nanocombinatorics for rapid screening of nanomaterials for a multitude of properties. (credit: Peng-Cheng Chen/James Hedrick)

The discovery power of the gene chip is coming to nanotechnology, as a Northwestern University research team develops a  tool to rapidly test millions — and perhaps even billions — of different nanoparticles at one time to zero in on the best nanoparticle for a specific use.

 

How exercise improves memory

How exercise improves memory - June 24, 2016

The hippocampus in the brain switches to fat as an energy source after glucose is depleted from exercise), leading to release of BDNF, associated with cognitive improvement. Researchers have found out how.

Physical exercise after learning improves memory and memory traces if the exercise is done four hours later, and not immediately after learning, according to findings recently reported (open-access) in the Cell Press journal Current Biology.

It’s not yet clear exactly how or why delayed exercise has this effect on memory. However, earlier studies of laboratory animals suggest that naturally occurring chemical compounds in the body known as catecholamines, including dopamine and norepinephrine, can improve memory consolidation, say the researchers at the Donders Institute at the Radboud University Medical Center in the Netherlands. One way to boost catecholamines is through physical exercise.
