Single 'nanoconfined' molecules: Making and breaking of chemical bonds

Sciencedaily.com 

Researchers around the world are working to develop efficient materials to convert CO2 into usable chemical substances -- work that is particularly pressing in view of global warming. A team has discovered a new and promising approach: catalytically active molecules are nanoconfined -- meaning they are put into an environment that leaves very little space for the single molecules -- on a surface that serves as a conductive electron supplier. These molecules promote specific chemical reactions. Such... Читать дальше...

A switch telling the brain when to learn and when to remember

Sciencedaily.com 

The memory system alternates between periods of learning and remembering. These two functions are controlled by different neural circuits. Using an animal model, scientists recently identified a neural signal in the hippocampus, a brain region essential for forming and recalling memories, that enables the brain to alternate between remembering and learning modes.

Air pollution may spur irregular heart rhythms in healthy teens

Sciencedaily.com 

A first-of-its-kind study examining the impact of air pollution on healthy teenagers found that air pollution may trigger an irregular heart rhythm within two hours after exposure. Reducing the risk of irregular heart rhythms -- known as arrhythmias -- during adolescence may help reduce the risk of sudden cardiac death and developing heart disease in adulthood. Wearing face masks and avoiding vigorous physical activity may be warranted on high pollution days, especially during early morning hours, researchers said.
