Theologians once pondered how many angels could dance on the head of a pin. Not to be outdone, researchers who build nanoscale electronics have developed microsensors so tiny, they can fit 30,000 on one side of a penny.
Self-assembly is the process that built up life and its surrounding, atom-by-atom. Now, a team of scientists has demonstrated the fundamental principles of a universal self-assembly process acting on a range of materials starting from a few atoms-large quantum dots up to nearly 100 trillion atoms-large human cells.
Medical researchers have achieved unprecedented resolution capabilities in single-molecule microscopy to detect interactions between individual molecules within intact cells.
Researchers discovered, while on their way to better understanding protein nanowires, how to use biological, electricity conducting protein filaments to make a neuromorphic memristor, or 'memory transistor', device.
Deep brain stimulation (DBS) is an effective treatment for many neurological disorders, but despite its widespread utilization the underlying mechanisms and downstream effects of DBS remain poorly understood. One major issue to understand the therapeutic mechanism of DBS is to map the wide variety of brain responses at both the local and global levels. Researchers have developed a highly MRI-compatible graphene fiber electrode that enables full activation pattern mapping by functional magnetic resonance imaging under DBS without the occurence of artifacts resulting from magnetic field interference.
