Dr Paul Robertson – Pamela: Integrating Modelling and Machine Learning for Autonomous Robotics
Machine learning is rapidly advancing the decision-making capabilities of today’s computers, yet without an in-depth knowledge of the programming it involves, many engineers and researchers find current technology inaccessible. Dr Paul Robertson at Dynamic Object Language Labs (DOLL) in Massachusetts believes that a solution to the issue may have been hidden in plain sight: machine learning itself. His ideas have now culminated in ‘Pamela’: a universal, open-source language capable of modelling real-world systems, and building plans to overcome challenges. The language and its related tools could soon open up significant opportunities in the emerging field of artificial intelligence.
Dr Joe Huba – Plasma Bubbles after Sunset: Simulating Instabilities in the Ionosphere
Many kilometres above the Earth’s equatorial region, something strange occurs for several hours in the late evening: vast bubbles of plasma form in the upper atmosphere, which quickly rise upwards into space. Dr Joe Huba at Syntek Technologies in Virginia aims to gain a better understanding of this complex process, by recreating it through computer simulations. His team’s work is providing researchers with a more complete understanding of Earth’s atmosphere, and could also provide critical insights for satellite systems that communicate using radio waves, as well as global positioning systems.

The latest version of the interferometer – the Advanced Virgo – was built in 2012, and has been operational since 2017. Virgo is part of a scientific collaboration of more than 100 institutes from 10 European countries. By detecting and analysing gravitational wave signals, which arise from collisions of black holes or neutron stars millions of lightyears away, Virgo’s goal is to advance our understanding of fundamental physics, astronomy and cosmology. In this exclusive interview, we speak with the spokesperson of the Virgo Collaboration, Dr Jo van den Brand, who discusses Virgo’s achievements, plans for the future, and the fascinating field of gravitational wave astronomy.
Dr Afsaneh Lavasanifar – Improving Cancer Treatment with Nanomedicine
Cancer is one of the most common causes of mortality worldwide and diagnosis rates are continually increasing. An estimated one in three women and one in two men will be diagnosed with a form of cancer at some point throughout our lives. For many cancer types, chemotherapy and radiotherapy are the chosen treatment methods, but their success rates are surprisingly limited, and both can cause serious side-effects. Dr Afsaneh Lavasanifar and her research group at the University of Alberta have set out to develop drug-delivery systems to improve the effectiveness of cancer treatment and reduce side-effects. Their research involves the targeted delivery of drug-loaded nanoparticles directly to tumour tissues.

Through a combination of physical theories and the latest computer simulations, Dr Shantanu Basu at the University of Western Ontario in Canada is offering intriguing new insights into how these structures originate. His theories could help astronomers to understand the very earliest stages of bodies ranging from those too small to become stars, to the vast, all-devouring heavyweights that reside in the centres of galaxies.
Dr Robert Ebert – Pinpointing the Physics of Energetic Storm Particles Observed in Near Earth Orbit
When the Sun’s surrounding corona erupts, colossal streams of charged particles are ejected out into interplanetary space, and go on to interact with the material that resides there. Dr Robert Ebert at the Southwest Research Institute and his colleagues combine observations from spacecraft with the latest computer models to uncover the mysteries of these interactions. Their research focuses on advancing astronomers’ understanding of the highly energetic processes that play out in the void that comprises over 99% of the Solar System’s volume.
Professor Yoshio Waseda – Understanding the Atomic Structure of New Materials
Materials science – the discovery and characterisation of new materials – drives forward the creation of new technology. In particular, the development of thin films of materials is vital to the electronics industry, as they are used in various device components such as displays and sensors. The properties of these materials are defined by their atomic structure, and until recently it was a major challenge for scientists to accurately characterise this. Towards this aim, Professor Yoshio Waseda and his team at the Institute of Multidisciplinary Research for Advanced Materials have developed a novel method for characterising the atomic structure of thin films.
Dr Donald Fosnacht – Bringing Biomass into the Renewable Mix
A completely decarbonised society may now be firmly on the agendas of many businesses and world leaders, but the paths that need to be taken to realise this goal still remain far from clear. Dr Donald Fosnacht at the University of Minnesota believes that biomass is currently underappreciated as a way to realise a carbon-neutral society. The techniques his team has developed have already been demonstrated on industrial scales in some cases, and even promise to improve the lives of some communities in the developing world. With further research, Dr Fosnacht hopes that biomass will transform the ways in which our industries and power stations function.
Dr Philip Myers – A Family Affair: Exploring Early Star Formation
We know much about fully-formed stars, such as our Sun, but the very earliest processes of star formation are still a mysterious area of astrophysical research. The original idea that a single new-born star (or ‘protostar’) forms within a single molecular cloud core has been dispelled by the discovery of new-born pairs, triplets, or even larger groups of protostars in cores. Dr Philip Myers of the Center for Astrophysics | Harvard and Smithsonian has been observing and interpreting protostar formation for many years using a range of sophisticated telescopes and theoretical models.
Dr Shadia Habbal | Dr Miloslav Druckmüller – Hiding the Sun: Coronal Discoveries during Total Solar Eclipses

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 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.
CERN’s Future Circular Collider
Geneva-based particle physics research centre, CERN, plans to build a £20bn particle accelerator that is almost four times longer than today’s largest and most powerful accelerator, the Large Hadron Collider (LHC). At 100 kilometres long, this ‘Future Circular Collider’ (FCC) will be able to accelerate particles to unprecedented speeds, leading to collisions that are 10 times more energetic than those achieved on the LHC. Measurements taken from such collisions will help scientists in solving several longstanding mysteries in physics, such as the nature of dark matter. In this exclusive interview, we speak with CERN physicist Dr Matthew McCullough, who tells us about CERN’s plans for the FCC, its remarkable capabilities, and the new physics that he is most excited to explore.
TEMPO: Monitoring North America’s Pollution from Space
Created by sources ranging from campfires to cargo ships, air pollution is incredibly difficult to track. This has meant that the full impacts of air pollution are almost impossible to assess, but a solution is on the horizon. The TEMPO instrument (tempo.si.edu), built by Ball Aerospace to Smithsonian Astrophysical Observatory specifications and managed by the NASA Langley Research Center, will soon provide an all-encompassing view of pollution across North America. As part of a global constellation of satellite air quality missions, TEMPO will soon provide us with the most extensive view of pollution ever achieved, along with its impacts, allowing us to tackle it more effectively than ever before.

To explore the issue, Dr Andreas Keiling of the University of California at Berkeley studies the complex processes that take place during these so-called solar storms. His work has now begun to unravel the mysteries of the electromagnetic battleground far above Earth’s surface.
Dr Baowei Fei – A New Technique for Targeted Prostate Cancer Biopsies
Two-dimensional transrectal ultrasound (TRUS) guided biopsy is the standard method for prostate cancer diagnosis. However, the technique is limited in one respect – it can be prone to sampling error. Cancers can be missed, or their severity grossly underestimated. To address this, Dr Baowei Fei, from the University of Texas (UT) at Dallas and UT Southwestern Medical Center, is pioneering a technique that merges positron emission tomography (PET) with TRUS to detect prostate cancer more accurately than before.
