Fine-tuning Polymers as Flexible Antenna Substrates for Aircraft

Fine-tuning Polymers as Flexible Antenna Substrates for Aircraft

The pursuit to design more lightweight aircraft that can travel over greater distances never ceases. One area that has received much attention is the development of lighter and more aerodynamic antennas. Researchers at the NASA Glenn Research Center are at the forefront of this effort. The research team, which includes Jessica Cashman, Baochau Nguyen, Haiquan Guo, Marcos Pantoja, Kevin Cavicchi, and Mary Ann Meador, is designing flexible polymer materials that can be used to construct lightweight, low-drag antennas that lie along the surface of an aircraft.

Dr Mark Westhusin – A Bright Future for Transgenic Livestock

Advancements in genetic technologies have made precise gene editing a reality. Used extensively to develop crops that exhibit higher yields and resistance to pests and diseases, genetic modification could also transform livestock production. Building on decades of animal cloning research, Dr Mark Westhusin from the Reproductive Sciences Laboratory at Texas A&M University is using genetic and reproductive technologies to improve livestock for food, medicine, and medical research.

Dr Li-Qing Jiang – Mapping the Impact of Carbon Emissions on the Oceans

Dr Li-Qing Jiang – Mapping the Impact of Carbon Emissions on the Oceans

The climate crisis and the chemistry of the oceans are inextricably connected. The oceans have absorbed close to a third of our carbon dioxide emissions since the beginning of the Industrial Revolution, leading to an increasingly acidic environment and making it more difficult for organisms such as corals, molluscs, and plankton to form their shells and skeletons. Mapping future changes in ocean chemistry is the first step in developing mitigation strategies. However, our knowledge of the future state of the oceans relies on mathematical models that are often not calibrated with modern ship-based observations. Dr Li-Qing Jiang of the University of Maryland and his collaborators are improving ocean acidification predictions by coupling millions of past and present ocean chemistry measurements with the best model projections at each location of the global ocean.

Dr Peter Kevan | Charlotte Coates – Exploring Micrometeorology in Plant Stems and Flowers

As complex living organisms, plants can often display intricate interactions with the air inside and around them. So far, however, many characteristics of these processes have gone largely unexplored. In their research, Charlotte Coates and Dr Peter Kevan at the University of Guelph combine field surveys with advanced imaging technologies to study the ‘micrometeorology’ that takes place in and around the stems and flowers of many plants. Their discoveries are shedding new light on how these plants grow and reproduce, and how some species are providing ideal habitats for ecologically damaging insects.

Dr Israel Liberzon – Unravelling the Neural Networks Underpinning Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) is a prevalent psychiatric condition, significantly impacting the lives of millions of people globally. Sadly, symptoms often persist despite treatment. A better understanding of the brain abnormalities involved in PTSD is crucial to improving therapy development. Dr Israel Liberzon and his colleagues at the Texas A&M Health Sciences Centre have been working to uncover the dysfunctional neural networks that contribute to PTSD symptoms to inform the development of more effective interventions.

While the world’s attention is focused on eradicating COVID-19, we must not forget that unsustainable farming practices and the ensuing biodiversity declines were leading factors in the emergence of this devastating disease. To prevent future pandemics, we must now find new ways to feed the human population while also protecting and restoring Earth’s biodiversity. Such sustainable agricultural methods have a range of other positive impacts, including climate change mitigation, improved animal welfare, and reduced social inequality.

Professor Maria Ngu-Schwemlein – Developing Mercury Immobilisers and Antibiotic Enhancers

Professor Maria Ngu-Schwemlein – Developing Mercury Immobilisers and Antibiotic Enhancers

The rise of antibiotic-resistant strains of bacteria and the ubiquitous nature of mercury in the environment are two major health hazards and concerns faced today. Professor Maria Ngu-Schwemlein and her team from the Winston-Salem State University, USA, are addressing these issues by developing biomolecules that can bind and immobilise toxic mercury ions more effectively. Together with Professor Ngu-Schwemlein’s collaborators, the team is also investigating carbon nanodots as molecular scaffolds to enhance antibiotics in combating antimicrobial resistance.

SciComm Corner – How Virtual and Augmented Reality Could Aid Science Communication

Virtual Reality (VR) and Augmented Reality (AR) are immersive technologies that allow users to experience media content in more engaging ways, as if it was playing out in their immediate surroundings. This is achieved through the use of smart headsets, glasses, and other wearable devices with LCD or OLED screens integrated in them, such as Oculus Rift, HTC Vive, Playstation VR, and Microsoft HoloLens.
