A 'frozen reaction' as key to eco-friendly chemical catalysis

Enzymes are naturally existing biocatalysts of great potential for application in sustainable chemistry. Yet, controlling enzyme reactions at atomic level is still a challenge in biology. Scientists at the Max Planck Institute ...

Electrons move like light in three-dimensional solid

Electrons were observed to travel in a solid at an unusually high velocity, which remained the same independent of the electron energy. This anomalous light-like behavior is found in special two-dimensional materials, such ...

Study finds ancient clam beaches not so natural

In their second study to be published in just over a year, an SFU led team of scientists has discovered that ancient coastal Indigenous people were more than hunter-gatherers.

First exoplanet visible light spectrum

Astronomers using the HARPS planet-hunting machine at ESO's La Silla Observatory in Chile have made the first-ever direct detection of the spectrum of visible light reflected off an exoplanet. These observations also revealed ...

Student creates powerful catalyst from potassium

Of what use is a newborn baby? This rhetorical question, variously attributed to Benjamin Franklin, Michael Faraday and Thomas Edison, is meant to suggest that a novel discovery or invention whose ultimate utility is not ...

International experts analyze impacts of Ethiopian dam

According to present plans, the Grand Ethiopian Renaissance Dam (GERD)—now under construction across the Blue Nile River in Ethiopia—will be the largest hydroelectric dam in Africa, and one of the 12 largest in the world. ...

Invisible inks could help foil counterfeiters of all kinds

Real or counterfeit? Northwestern University scientists have invented sophisticated fluorescent inks that one day could be used as multicolored barcodes for consumers to authenticate products that are often counterfeited. ...
