Naturally occurring enzyme does the unexpected

Enzymes are molecular machines that produce specific molecules with exquisite efficiency and near perfect control of the end product. Chemists have long sought to employ enzymes in laboratory settings, but are often limited to the specific reactions each enzyme evolved to execute. The efficiency and... click to read more

Study gets the buzz on stingless bee honey

Given that honeybees (Apis mellifera) are so infamous for their stings, they are loved nonetheless for their golden honey. The much smaller stingless bees (Meliponini) produce honey as well, but are remarkable for their lack of sting! Like the more well-known honeybees, stingless bees are... click to read more

Machine adapting to its environment

What if a robot could adapt itself to a given circumstance more like a human? It sounds like a science fiction movie, but it may become a reality, using neuromorphic (or brain-like) computing. When we look at an object like a flower, or a person,... click to read more

Stress management in lithium-sulfur battery: some space to breathe

Lithium-ion batteries, of the type we can find in any house-hold, have changed the world. But as society moves away from fossil fuels, we will need cheaper and greener technologies for storing energy to support renewable electricity generation and electric vehicles. The Lithium-Sulfur (Li-S) battery... click to read more

A quantum step forward in high pressure science

Under normal conditions, some materials are naturally better at conducting electricity than others. By applying high enough pressure, some materials that normally block the flow of electricity, like sulfur, can become conductors better than copper or gold. A wire of such "superconductor" could theoretically deliver... click to read more
