Levenson and a team of cancer researchers from Long Island University in the United States of America are working to advance our understanding of how and why prostate cancer develops. Their important work also demonstrates how compounds found in foods such as grapes and blueberries may help prevent the development and progression of cancer.
Dr Chung Chi Chou | Upgrading Sugar Cane Mill to Produce Refined Sugar: Making Sugar Production More Efficient (Patented)
The sugar industry is a giant, producing hundreds of millions of tonnes of refined sugar each year. In the USA, most sugar is produced from sugarcane, but the process of growing sugarcane, milling it into raw sugar, then refining it into the product we’re familiar with, is remarkably energy- and water-intensive. Dr Chung Chi Chou proposes a process to improve the efficiency of sugar production by combining the milling and refining stages in one plant, increasing profits and reducing the environmental impact of the sweet stuff.
Dr Jeong-Wook Kim | Car Talk: Active Phased Array Antenna System Design for Vehicle-to-Everything Communication
Information exchange between vehicles and the world around them offers many exciting possibilities. Drivers could be provided with real-time information on the speed and behaviour of other cars around them, live updates from city infrastructure to vehicles could improve traffic flow, and vehicle-to-mobile communication interfaces could warn pedestrians of busy crossings. However, such advances require a strong and stable signal to ensure reliable and effective communication. Dr Jeong-Wook Kim from the Korea Advanced Institute of Science and Technology has developed a new design for vehicle communication antennas, improving the ability of individual vehicles to exchange information with the world around them.
Dr Ahmet Mete Kök | Cultivating a New Generation of Cybersecurity Professionals
Computer systems underpin nearly every aspect of modern life, but they’re more vulnerable than many people realise. Threats to cybersecurity can come from anywhere in the world, at any time, and the techniques that malicious agents use are constantly evolving. As such, well-trained cybersecurity technicians are absolutely critical to our modern world, but there is a scarcity of such individuals. Now, Dr Ahmet Mete Kök and his colleagues have developed a new online certificate degree program at the Borough of Manhattan Community College, focused on educating and training a new cohort of cybersecurity technicians from diverse backgrounds.
Dr Daisuke Minakata – Sunshine and Organic Molecules in Water
Organic molecules dissolved in rivers, lakes, seas and oceans are essential to plant and animal life. Some of these molecules are also degraded and enter a complex cycle of carbon, nitrogen and sulphur containing compounds. Surprisingly, scientists currently have a limited understanding of the fate of these molecules. Dr Daisuke Minakata and his colleagues from Michigan Technological University are involved in an ambitious programme to overcome this critical knowledge gap.
Dr Kay Cooksey | Developing Intelligent Packaging Solutions to Prevent Foodborne Illnesses
Many of us avoid foods that contain ingredients we haven’t heard of. However, many of these chemicals are beneficial because they prevent the growth of bacteria that cause foodborne illnesses. Although food quality standards have improved dramatically, outbreaks of foodborne illnesses are still common. Luckily, we have one line of defence to exploit: antibacterial food packaging. Dr Kay Cooksey of Clemson University is leading ground-breaking research to overcome the hurdles associated with antibacterial food packaging, bringing it one step closer to market.
Kevin R. Supak | Tapered LADs: Acquiring Cryogenic Liquid Propellants in Deep Space
To carry out complex manoeuvres such as orbit insertion, large spacecraft on long voyages must carry tanks of liquid propellants, kept at ultra-cold temperatures. In existing designs, however, heat leaking into these tanks can form unwanted vapour bubbles in the channels required to extract their contents – which are especially difficult to remove in the microgravity environment of deep space. In their research, a team at the Southwest Research Institute presents a simple solution to this problem – through which the sides of these extraction channels are tapered, allowing vapour bubbles to escape. Results from recent microgravity testing of this technology could lead to exciting new opportunities for future space missions.
Dr Alessia Besford | Understanding the Crown of a Nanoparticle
Medical nanoparticles are an innovative method of delivering drugs to highly specific locations in the body, such as tumours or across the blood-brain barrier. Once a nanoparticle has entered the bloodstream, it forms a crown of surrounding biomolecules called a corona. The composition of this corona depends on its biological environment and the material of the nanoparticle itself and it has significant implications for how the nanoparticle interacts with the human body. Dr Alessia Besford from the Leibniz Institute of Polymer Research Dresden studies these interactions and how they can be refined to develop more effective medical nanoparticles.
Dr John Slough | Fuelling the Next Generation of Rockets with Nuclear Fusion
Most rockets combine liquid hydrogen and oxygen to throw out extremely hot, expanding gas as a propellant; however, there are limits to the efficiency of this system. Dr John Slough and his colleagues at MSNW and the University of Washington have been developing new ways to propel spacecraft, with inspiration from the process that powers the Sun: nuclear fusion. Using an innovative design, his fusion-driven rocket converts the energy output of a fusion reaction directly into the propellant, opening new opportunities for space travel and exploration.
Logan Kossel | John Pfotenhauer – Advancing Cryogenic Technologies Through Pulsating Heat Pipes

Through their research, they hope to boost the performance of pulsating heat pipes even further – potentially leading to new breakthroughs in many technologies that rely on cryogenic temperatures.
Professor Rui Martins | Building a Microelectronics Research Group from the Ground Up
Microelectronics are the minuscule components that power our modern world, from your smartphone to the systems that keep jet airliners in the sky. These essential components, such as transistors, resistors, capacitors, and inductors are the building blocks of microchips – the tiny computing units that process vast quantities of binary information. However, the world around us isn’t binary. Engineers must develop ways to translate between the analogue world that we inhabit and the binary world of chips. Over the last 30 years, Professor Rui Martins of the University of Macau has built a world-renowned research lab – the State Key Laboratory of Analog and Mixed-Signal VLSI – focused on further bridging the gap between analogue and digital.
Yiqiao Yin | Tracking Deforestation with Neural Networks
Forests are key to Earth’s biodiversity and the global ecosystem, hosting 80% of the planet’s plant biomass and two-thirds of all mammal species. However, they are also in decline; each year, around five million hectares of woodland are lost to logging and wildfires. Tracking this loss is essential to controlling and mitigating deforestation, but this requires careful interpretation of satellite imagery. Yiqiao Yin, Kieran Pichai, Benjamin Park and Aaron Park have developed a model to automatically identify forests from these images. Their new approach is already showing huge promise.
Yiqiao Yin | Seeing Deep into the Lungs with Deep Learning
X-rays and other forms of medical imaging let doctors peer into the body, revealing the internal structure of organs and tissues without invasive surgery. Doctors use the results to identify abnormalities such as broken bones, diagnose diseases such as cancer, or even monitor the health of a foetus within the womb. Although this technology is remarkable, the images aren’t useful in isolation. Experts must analyse the resulting data and parse what is healthy or unhealthy from the noise. Yiqiao Yin, Jaiden Schraut, Leon Liu and Jonathan Gong have created new machine learning technologies to support that crucial interpretation, focusing on X-rays and lung health.
Dr Michael J Webber | A Comprehensive Assessment of a Chinese Water Management Project

Today, many researchers focus on creating materials that can replace damaged bone tissue, which often cannot heal naturally. Dr Susmita Bose and her team at Washington State University have been researching ways to engineer exciting new materials that mimic the structure of natural bone, allowing us to live happier, healthier, and longer lives.
Steve Schmalz | An Innovative Circuit Breaker for Renewable Power Grids
A key step towards a carbon-neutral future could be reached through dispersed power grids, featuring networks of local-scale renewable energy and battery storage plants. To prevent these power grids from damaging themselves and their surroundings when electrical faults arise, they must be integrated with ‘circuit breakers’, which temporarily interrupt the current flowing through them. However, currently available circuit breakers cannot handle the medium-voltage direct currents best suited for these grids. Through an innovative new circuit breaker design, Steve Schmalz and his colleagues at Eaton Corporation, the Illinois Institute of Technology (IIT), Virginia Tech and the National Energy Technology Laboratory (NETL), hope that this challenge will soon be overcome.

Dairy Brain is a toolkit introduced by Dr Victor E. Cabrera and his colleagues at the University of Wisconsin – Madison, which integrates the data streams collected by different software onto a single platform, and applies the latest algorithms to reveal novel insights. The technology could soon enable farmers and industry professionals to make far better use of the latest techniques in data analysis – and may even lead to new advances in efficiency and sustainability.
Dr Mark Gleason – Intelligent Spraying: Improving Prospects for Sustainable Pesticide Use
Pesticides may be essential in ensuring abundant and healthy yields of many crops, but so far, the techniques used to spray them have led to considerable environmental damage. In his research, Dr Mark Gleason, a plant pathologist at Iowa State University, assesses the performance of new technologies that can deploy pesticides on apple trees in more efficient and less hazardous ways. These approaches enable farmers to minimise pesticide use without sacrificing crop yields. Through combining laser-based ‘LiDAR’ (light detection and ranging) technology with disease-warning systems to time sprays efficiently, his project team hopes to offer more sustainable and environmentally friendly options for apple growers.
Dr Marolo Alfaro – Protecting Arctic Infrastructure as the Permafrost Degrades
Roads, bridges, and airports are now being built all across the Arctic. However, as this happens, the future of the sturdy permafrost these structures are built upon is looking increasingly uncertain. In his research, Dr Marolo Alfaro at the University of Manitoba uses both computer modelling and real-world sensing to assess the impact that the Arctic’s warming climate is having on this infrastructure. Starting from analysis of a newly-constructed highway in Canada’s Northwest Territories, his team’s efforts could soon provide local communities with vital guidance as to how their infrastructure should be maintained and protected.
