Scientists reveal a phenomenon that is 'radically different from textbook physics' and this work has led to the discovery and characterisation of a new family of quasiparticles found in graphene-based materials. Called Brown-Zak fermions these extraordinary particles have the potential to achieve the Holy Grail of 2D materials by having ultra-high frequency transistors which can in turn produce a new generation of superfast electronic devices.

Generally it is believed that core quantum dots (QDs) are good reducing agents and are used for that purpose in solar hydrogen generation and various organic transformations. However, core QDs are very unstable. Core/shell dots are more robust, but the shell minimizes redox activity. Researchers now demonstrate that this isn't perfectly true. In fact, they found that certain core/shell materials are a better reducing agent than the core alone. Most importantly, core/shell QDs are substantially more robust than the core alone.

With their ability to resist conventional chemotherapy drugs, cancer stem cells (CSC) are really difficult to kill, and they are considered to be key drivers in metastasis, the spread of cancer via the blood stream. If the frequency of CSCs could be diminished, tumors would be rendered less aggressive and more responsive to conventional therapy. This approach is known as differentiation therapy and has considerable therapeutic potential. Scientists now report an approach capable of efficient differentiation of CSCs into non-CSC phenotypes.
