How sweet can you get?

Plant-derived sweetener thaumatin becomes 1.7 times sweeter after amino acid swap

25-Feb-2016

A sweeter version of a widely used plant-derived sweetener is on the way. Researchers have found a way to make thaumatin -- one of the sweetest natural sugar substitutes on the market -- even sweeter. "Making natural sweeteners stronger could be a huge plus to the food industry, especially as ...

Graphene becomes superconductive

Electrons with 'no mass' flow with 'no resistance'

18-Feb-2016

Graphene is a single-atomic carbon sheet with a hexagonal honeycomb network. Electrons in graphene take a special electronic state called Dirac-cone where they behave as if they have no mass. This allows them to flow at very high speed, giving graphene a very high level of electrical ...
