Dr Peter Evans – Retro-Causality: Unravelling the Mysteries of Quantum Cosmology
Despite many years of research aiming to unite quantum mechanics with cosmological theories, researchers in fields across physics and philosophy remain in disagreement about a solution. Now, Dr Peter Evans at the University of Queensland sheds new light on the debate. He argues that on quantum scales, the idea of cause and effect does not need to follow the one-way passage of time, as we understand it. If correct, his theories could dispel some of the most puzzling mysteries of quantum theory – a significant step forward in understanding the true nature of the universe.
Dr Michael Rothrock – Ensuring Food Safety of Pasture-Raised Chicken
Pasture-raised chicken is viewed as a more ethical option compared to that reared in overcrowded barns. However, pasture-raised birds are more likely to come in contact with bacterial pathogens that can be dangerous to consumers. Dr Michael Rothrock and his colleagues, at the Egg Safety and Quality Research Unit of the United States Department of Agriculture – Agricultural Research Service, investigate how environmental factors can lead to the contamination of pasture-raised chicken with harmful bacteria. Through their research, the team hopes to find ways of ensuring the safety of this popular food.
Dr Peter McEvoy – Biological Control in the Light of Contemporary Evolution
‘Biological control’ refers to the practice of controlling invasive pest populations by introducing their natural enemies into an ecosystem. Although biological control can reduce reliance on toxic chemicals and protect natural ecosystems, this approach is not without its challenges. Dr Peter McEvoy and his colleagues at Oregon State University discovered that certain biological control organisms show unexpectedly fast rates of evolution, which can lead to unforeseen impacts on ecosystems and agriculture. These scientists believe that it is time to develop an all-embracing theory to help assess the evolutionary potential of biological control organisms that may influence the efficacy and safety of future introduction programs.
Dr Amber Adams-Progar – A Holistic Approach to Improving Dairy Farming
Dairy farming is a tough business, where farmers experience countless challenges on a regular basis, from ensuring the health and welfare of their cattle to protecting the safety of their employees. Dr Amber Adams-Progar and her team in the Department of Animal Sciences at Washington State University are involved in many research projects, which aim to improve various aspects of the dairy industry, by protecting farm profits, worker safety and animal welfare.
Dr Bianca Eskelson – Understanding Wildfire Effects to Inform Better Forest Management
Forest wildfires are increasing in frequency and severity across the globe, and this trend is expected to continue as climate change worsens. However, measuring the impacts of wildfire on forest ecosystems is extremely difficult. Dr Bianca Eskelson from the University of British Columbia and her colleagues at the United States Forest Service utilise vast datasets and investigate conditions before and after wildfires, to quantify their immediate and long-term effects on forest ecosystems. The team’s research is improving our understanding of the effects of forest wildfires to inform better forest management.
Dr Elena Galkina – Immune Control of Initiation and Progression of Atherosclerosis
Atherosclerosis is a global health issue. Atherosclerosis is a multifactorial chronic inflammatory disease characterised by the accumulation of modified lipoproteins and immune cells in the aortic wall, vascular dysfunction, low-grade chronic inflammation, and formation of dangerous atherosclerotic plaques within the medium and large size vessels. Atherosclerosis is a prominent cause of cardiovascular diseases and mortality in many countries and this disease is closely associated with type 2 diabetes. Dr Elena Galkina, Professor of Microbiology and Molecular Cell Biology at Eastern Virginia Medical School, USA, has been working to determine the immune processes involved in an attempt to identify much-needed novel therapies.

Dr Scot Rafkin – Exploring the Weather of Titan and Mars
The moons and rocky planets of our Solar System may be remote, unfamiliar worlds, but even on the very strangest of them, the weather on those with atmospheres is not wholly unlike our own. Dr Scot Rafkin, a planetary scientist at the Southwest Research Institute, believes that the small-scale patterns their atmospheres exhibit are directly comparable with Earth’s weather. Based on the results of computer models simulating the atmospheres of Titan and Mars, he argues that these local and regional behaviours are significantly underappreciated in planetary science.
Dr Nancy Chabot | Dr Carolyn Ernst | Ariel Deutsch – Icy Discoveries on Our Innermost Planet
The location of water in our solar system may hold the key to understanding how the planets evolved, and indicate other potential places to find life away from Earth. Dr Nancy Chabot and Dr Carolyn Ernst of Johns Hopkins University Applied Physics Laboratory, and Ariel Deutsch at Brown University, use data from NASA’s MESSENGER mission to understand how much ice exists on Mercury and how it may have arrived there.
