Dr Klaudio Peqini | Professor Bejo Duka – Mapping Flows at Earth’s Core–Mantle Boundary

Dr Klaudio Peqini | Professor Bejo Duka – Mapping Flows at Earth’s Core–Mantle Boundary

The magnetic field that enshrouds Earth is generated by processes deep within the planet’s interior, which geologists still don’t fully understand. Among the effects that remain poorly studied are brief variations in the strength of the magnetic field, which occur over timescales of several decades. Through detailed mathematical analysis, Dr Klaudio Peqini and Professor Bejo Duka, both at the University of Tirana in Albania, explore how these variations could arise from changes in the flows of material at the boundary between Earth’s core, and its thick layer of mantle.

Dr Angelica Tarpanelli | Keeping an Eye in the Sky on Rivers

Across the globe, climate change is driving extreme weather events, such as floods and droughts, with increasing frequency, duration, and intensity. Accurately assessing the flow of water through rivers – or river discharge – could help us forecast extreme weather events and prevent loss of life. Sensors onboard satellites could provide more accurate and in-depth measurements of river variables than ever before. As part of the RIDESAT project, funded by the European Space Agency, Dr Angelica Tarpanelli and her team of researchers from Italy and Denmark investigate how combining remote sensing data from satellites could support river discharge assessments.

Dr Peter Melchior | SCARLET: Exploring the Universe in Unprecedented Detail

Wide-area scans of the sky are an important tool for astronomers as they seek to learn more about the universe. However, as the latest observation techniques have become increasingly sensitive, faint objects within these surveys can appear to blend together. Through his research, Dr Peter Melchior at Princeton University presents a computer-based framework for disentangling these blended sources, and for artificially reconstructing the components they contain. Named SCARLET, the technique could soon help astronomers to study the depths of the observable universe in unprecedented levels of detail.

Optimising Lubricant Oils to Boost Engine Efficiency | Ken Hope

Optimising Lubricant Oils to Boost Engine Efficiency | Ken Hope

The engine of a typical passenger vehicle is made up of hundreds of mechanical parts. These parts require lubrication to prevent them from overheating and to keep them working efficiently. Ken Hope and his team at Chevron Phillips Chemical, headquartered in Texas, have analysed the extent to which different types of lubricant oils reduce friction. They then used this data to estimate how an optimised oil mixture can achieve an overall improvement in engine efficiency.

Teaching Algorithms to Caption Ultrasound Images | Dr Mohammad Alsharid

Medical professionals require years of training before they can describe ultrasound images of developing foetuses. Dr Mohammad Alsharid and colleagues from the Institute of Biomedical Engineering and Nuffield Department of Women’s and Reproductive Health at the University of Oxford suggest that this task could one day be carried out by machine learning algorithms. In their latest study, the team showed how neural networks, trained by the expert knowledge of real sonographers, could convert subtle features within the images into accurate, readable captions.

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

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.

Dr Thomas Arciuolo | Dr Miad Faezipour – Yellowstone Caldera Supervolcano – A Solution to the Climate and Energy Crisis

The global climate crisis poses a major threat to human civilisation. The combustion of fossil fuels to generate energy is the primary cause of this crisis, due to the greenhouse gases released into the atmosphere. At the same time, the Earth faces another great crisis. Underneath Yellowstone National Park in Wyoming, USA, lies one of Earth’s most powerful volcanoes, which has the potential for an eruption that would be catastrophic to the entire world. Researchers Dr Thomas Arciuolo and Dr Miad Faezipour propose a solution to both of these problems, by harnessing the mighty energy reserve within the Yellowstone Supervolcano to generate clean, emission-free power – turning the Yellowstone curse into an immense blessing.
