Researchers study historical developments of the periodic system of chemical elements
Researchers study historical developments of the periodic system of chemical elements
In the 1860s, the chemists, Lothar Meyer and Dmitri Mendeleev, independently presented the first periodic system. Since then, the well-known tabular arrangement of the elements has been the guiding principle of chemistry. A team of researchers from the Max Planck Institute for Mathematics in the Sciences and the Interdisciplinary Center for Bioinformatics at the University of Leipzig provides computational approaches based on extensive data sets from the Reaxys chemistry database that explain the development of the first periodic systems.

Graphene scientists capture first images of atoms ’swimming’ in liquid
Graphene scientists from The University of Manchester have created a novel 'nano-petri dish' using two-dimensional (2D) materials to create a new method of observing how atoms move in liquid. Publishing in the journal, Nature , the team led by researchers based at the National Graphene Institute (NGI) used stacks of 2D materials including graphene to trap liquid in order to further understand how the presence of liquid changes the behaviour of the solid.

Native New Zealand tree puts the sting on pain
Native New Zealand tree puts the sting on pain
Researchers at The University of Queensland have found that a native New Zealand stinging tree produces toxins that could hold clues for future pain medication. In a quest to find new molecules that affect pain pathways, Dr Thomas Durek , Dr Sam Robinson and a team from UQ's Institute for Molecular Bioscience (IMB) studied toxins from the tree nettle known as ongaonga, one of New Zealand's most poisonous plants that can cause painful stings that last for days, and in severe cases can even be fatal.
