Dr Philip Norcott | Improving Nuclear Magnetic Resonance with SABRE-DREAM

Nuclear magnetic resonance, or NMR, is an excellent technique for studying molecules, and is also the process behind hospital MRI machines. NMR works by exposing a sample to a strong, constant magnetic field. Then, a weak, oscillating magnetic field is also applied, and the atomic nuclei in the sample respond by emitting electromagnetic signals. These signals have particular frequencies, which scientists use to identify molecules in the sample. As useful as it is, NMR has weaknesses. Dr Philip Norcott at the Australian National University identifies two fundamental flaws and proposes a technique to overcome them.

Gyroscopes are widely used to measure the orientations and rotation speeds of moving objects – but according to one pair of researchers, the techniques we currently use to measure them are introducing significant and easily avoidable errors. Through their research, Dr Sara Stančin and Dr Sašo Tomažič, both at the University of Ljubljana in Slovenia, introduce a mathematical framework which accounts for how all three rotations measured by a gyroscope happen simultaneously, rather than in a sequence.

Dr Alan Litchfield | Jeff Herbert – ReSOLV: Preventing Software Piracy with Cryptocurrency Blockchain Technology

Software piracy is a large and growing problem. The methods used to combat it are becoming increasingly complex as technology evolves, costing software publishers and users billions of dollars each year. Dr Alan Litchfield from the Auckland University of Technology and Jeff Herbert from Cybercraft, New Zealand, have developed a new method to suppress software piracy called ReSOLV. In this video, learn more about their innovative software validation method, which is based on cryptocurrency blockchain technology.
