The School of Physics and Astronomy was delighted to take part in the Midlothian Science Festival in October where we offered two physics-themed activities.
Escape room – locked in and clued up
Over 50 adults looked for clues to be able to escape from our specially designed physics lab within the time limit. The event was at times a bit stressful (on purpose!), but participants enjoyed the challenge. Many of the ‘prisoners’ in our lab were impressed to have been able to solve physics-related problems, with one participant reporting she "never would have thought she would have so much fun doing physics".
The escape room was designed by Cristina Cortes and Robbie Peal, undergraduate students who are members of our Physics Outreach Team, and our Ogden Outreach & NBIC Outreach Officer, Dr Jean-Christophe Denis.
Microbe mania
Our ‘Biofilms: Welcome to microbe city’ workshops attracted 60 children aged 6 to 10 and their families. Participants had the opportunity to undertake some biophysics research - a strong research strand in the School - through the National Biofilms Innovation Centre (NBIC). Workshops included designing the best combination of sticky tracks to avoiding rolling bacteria infecting a cathether, having a go at trying to remove ‘fake biofilms’ on giant mouth models, drawing what a microbial city might look like, and observing real biofilms under the microscopes. Apprentice biophysicists loved meeting researchers and learning about their work.
The event was designed and delivered by Dr Jean-Christophe Denis, and researchers, Prof. Cait MacPhee, Dr Gavin Melaugh and Dr Susana Direito, with the help of physics undergraduate students.

Congratulations to Castleview Primary School for being the overall winner of the 2019 Rolls Royce Science Prize and winner of the Eden Award.
Castleview Primary is a local school situated less than 2 miles away from the School of Physics and Astronomy, and a community partner we have worked closely with for the past 3 years.
Rolls Royce Science Prize
The Rolls-Royce Science Prize recognises excellence in science teaching across the full spectrum of teaching contexts. It also seeks to promote sustainable teaching ideas that address specific needs in schools and contribute to teachers’ continuing professional development.
Science engagement
Castleview Primary School had been shortlisted as one of six finalists for their project ‘People like me can do STEM’. The aim of this project was to raise aspirations and increase pupils’ confidence in STEM. Based in Craigmillar, an area of multiple deprivation in Edinburgh, the school recognised that their pupils’ science capital was not the same as others and saw it as their job to build it. In order to achieve this, the project sought to get the entire school and their families excited about science and create on-going partnerships with local STEM institutions.
Dr Jean-Christophe Denis (School of Physics and Astronomy’s Ogden Outreach Officer) and physics students and staff worked alongside colleagues from the University’s MRC Centre for Regenerative Medicine in delivering a range of science engagement activities, including the community science festival and science clubs.
Jean-Christophe, who lives in Craigmillar and is known within Castleview Primary as the ‘local physicist’ said:
The School of Physics and Astronomy is one of the world leading physics academic centres, and it's important that young people in the neighbourhood have the chance to access world class STEM education and opportunities. I am very pleased that our community engagement efforts have been recognised by such a prestigious award.
Kate Carter, class teacher at Castleview Primary School and project lead for the Rolls Royce Science Prize said:
We are all so proud, it is such a privilege. The award acknowledges with loud celebration that the UK STEM community share our belief that our young people deserve the same opportunities to develop science capital as others and that our innovative community approach is both pioneering and successful in achieving this.
The judges praised Castleview Primary School for their efforts to change preconceptions on who can be a scientist and for helping to raise positive ambitions by building relationships. They also highlighted the partnership approach and the involvement of parents. The project resulted in a 20% increase in students enjoying STEM and wanting to do STEM related roles, with parent’s perceptions of science positively increasing by 100%.
Eden Award
The Eden Award, selected by Sir Tim Smit, co-founder of the Eden Project, recognises the most environmentally focused project. This award highlighted Castleview Primary School’s belief in their young people and in the development of sustainable communities, recognising the neighbouring connection and partnership with Edinburgh BioQuarter and The University of Edinburgh.

New findings could aid the search for extraterrestrial life during future missions to Mars by making it easier to distinguish between fossils and non-biological structures.
Research which suggests that structures previously thought to be fossils may, in fact, be mineral deposits, could save future Mars missions valuable time and resources. Microscopic tubes and filaments that resemble the remains of tiny creatures may have been formed by chemical reactions involving iron-rich minerals, the study shows. Previous research had suggested that such structures were among the oldest fossils on Earth.
The discovery was made by astrobiologist Dr Sean McMahon, who is developing techniques to seek evidence that life once existed on Mars. He created tiny formations in the lab that closely mimic the shape and chemical composition of iron-rich structures commonly found in Mars-like rocks on Earth, where some examples are thought to be around four billion years old.
Dr McMahon created the complex structures by mixing iron-rich particles with alkaline liquids containing the chemicals silicate or carbonate.
This process – known as chemical gardening – is thought to occur naturally where these chemicals abound. It can occur in hydrothermal vents on the seabed and when deep groundwater circulates through pores and fractures in rocks.
His findings suggest that structure alone is not sufficient to confirm whether or not microscopic life-like formations are fossils. More research will be needed to say exactly how they were formed.
The study, published in the journal Proceedings of the Royal Society B, was funded by the European Union’s Horizon 2020 programme.
Dr Sean McMahon said:
Chemical reactions like these have been studied for hundreds of years but they had not previously been shown to mimic these tiny iron-rich structures inside rocks. These results call for a re-examination of many ancient real-world examples to see if they are more likely to be fossils or non-biological mineral deposits.
Astronomers at the University of Edinburgh’s Institute for Astronomy are currently studying an unusual comet. Known as 2I/Borisov, this comet is only the second one in history to be shown to have come from beyond our Solar System, following the discovery two years ago of 1I/‘Oumuamua.
While the first Interstellar Object (ISO) had very strange properties - it was small and had a very elongated shape, and showed almost no evidence of comet-like activity - Borisov appears more like the comets of our own Solar System. It shows a clear coma and tail, and this has allowed astronomers to measure its composition, through spectroscopic investigation of the unique signatures of gasses in the coma.
Edinburgh astronomers Cyrielle Opitom and Colin Snodgrass have been studying the comet using the UK’s telescopes in the Canary Islands (the Isaac Newton and William Herschel telescopes), and are now training the European Southern Observatory’s ‘Very Large Telescope’ (one of the most powerful in the world) on the comet as it moves into Southern hemisphere skies.
Results so far indicate that, despite its origin in the planetary system around a distant star, comet Borisov has a composition quite similar to our own Solar System’s comets. It appears to be closest in composition to a class of comets known as ‘carbon chain depleted’, which make up around a third of Solar System comets, and tend to come from the Kuiper Belt of icy bodies at the edge of the planetary region (the region where Pluto is found), rather than the much more distant Oort cloud at the very edge of the Sun’s influence, which is the source of long period comets.

The University of Edinburgh has received £650,000 to provide essential contributions to the DUNE experiment.
This is part of a UK multi-million pound investment in a global science project that brings together the scientific communities of the UK and 31 countries from Asia, Europe and the Americas to build the world’s most advanced neutrino observatory. DUNE (the Deep Underground Neutrino Experiment) is a flagship international experiment hosted by the United States Department of Energy’s Fermilab, which will be designed and operated by a collaboration of over 1,000 physicists.
Professor Stefan Söldner-Rembold of the University of Manchester, who leads the international DUNE collaboration as one of its spokespersons, commented:
DUNE has the unique potential to answer fundamental questions that overlap particle physics, astrophysics, and cosmology.
This £30M investment from UK Research and Innovations’ Science and Technology Facilities Council (STFC) is a four-year construction grant to 13 UK educational institutions and to STFC’s Rutherford Appleton and Daresbury Laboratories. UK scientists and engineers will design and produce components at the core of the DUNE detector, which will comprise four large tanks each containing 17,000 kg of liquid argon. The UK groups are also developing a state-of-the art, high speed data acquisition system, together with the computing systems and sophisticated software needed to record, interpret and exploit the data.
The University of Edinburgh’s School of Physics and Astronomy is constructing the computing and software infrastructure to process and simulate the data that will be recorded. The scale of DUNE will be second only to that of the LHC (Large Hadron Collider) programme, necessitating a global distributed system based upon the Worldwide Computing Grid. Edinburgh physicists and software engineers are working on the complex globally distributed data management system needed to catalogue and deliver the multi peta-Byte data sets to large data centres, as well as the development of artificial intelligence systems for recognising signals in the detector coming from neutrino interactions.
Neutrinos will be produced at Fermilab and fired through the earth to re-emerge some 1300km later in the underground mine where DUNE is situated. DUNE will study the behaviour of these neutrinos and their antimatter counterparts, antineutrinos. This will provide insight as to why we live in a matter-dominated universe where antimatter has largely disappeared. DUNE will also watch for neutrinos from supernovae, and will investigate whether protons live forever or eventually decay, bringing us closer to fulfilling Einstein’s dream of a grand unified theory.
Professor Peter Clarke, the DUNE lead at the University of Edinburgh commented:
This award is excellent news for the Particle Physics Group here in Edinburgh. DUNE will set a new standard for neutrino detector technology. It is particularly exciting to know that we will become part of an experiment that may discover matter antimatter asymmetry in neutrino interactions, as well as become part of the global supernova watching community.
Professor Franz Muheim, of the Particle Physics Experiment group said:
Neutrinos are fascinating particles and the scale of the experiment poses an exciting challenge to record the information from the detectors.
The UK universities involved in the project are: Birmingham, Bristol, Cambridge, Edinburgh, Imperial College London, Lancaster, Liverpool, Manchester, Oxford, Sheffield, Sussex, University College London and Warwick.

Students, staff, industry and supporters gathered to learn about the career development projects students completed over the summer, and to announce the winner of the best project report and poster.
The School of Physics and Astronomy runs a Career Development Scholarship programme, funding and supporting students to undertake research projects over the summer period.
This year 42 undergraduate students took part in the programme. Students can undertake an academic project based in the School or a project based in industry. Projects have a duration of around 8 weeks, and students are provided with a stipend of £1,500.
These projects enable students to gain new skills, experience different workplaces and create a network of contacts. In many cases, students also got the opportunity to work on problems with immediate real world applications.
Grace Alster, who is currently in year 4 of the BSc (Hons) Computational Physics degree was presented with £1000 for the best project poster and report. Grace’s project, on the behaviour of methane and water inside icy planets was titled ‘Computational molecular dynamics of methane and water mixture under extreme conditions using CASTEP’. She was awarded the prize by the Head of School, Prof Jim Dunlop.
Grace commented:
Undertaking a project in summer was a great way to gain insight into what postgraduate research is like. It has made me more informed about my options after graduating, and given me the kind of skills I will need whether I end up in industry or academia. I’m glad I took the opportunity, and very thankful to Lewis (Project Advisor) and Andreas (Project Supervisor) for all their help.
Project supervisor, Dr Andreas Hermann reported:
I am absolutely delighted for Grace to have won the prize for the best summer project poster and report - having seen the amazingly high standard of work produced by all summer students it must have been a tough competition! I always try to get summer students to work on projects we are currently puzzling over, so they see how real research looks like: there is a lot of communication, dedication, and some ingenuity - yet outcomes are always uncertain. Here, Grace looked at (under expert guidance by my PhD student Lewis Conway) how methane and water mix under conditions found inside icy planets; not a place we can go and study in situ, so accurate computational modelling is indispensable.
Lewis Conway, Project Advisor said:
It was great having Grace working with us over the summer. She did some great work collecting large data sets and writing Python scripts to analyse them. Thanks to Grace, the research project has a firm grounding on which we hope to develop.
I think these summer projects are incredibly useful. I did a summer project when I was an undergraduate and it definitely influenced my decision to pursue a PhD. I hope that Grace has found it equally as enlightening!

Dr Xin Ran Liu from the School of Physics and Astronomy joined fellow eminent scientists in Beijing on 31 October to present at the ‘Why The Dark Matters’ event, hosted by the Chinese Academy of Sciences (CAM), and jointly organised with the UK Research Institute (UKRI).
Dark Matter is the as-yet-undetectable substance that is thought to make up over 80 percent of the mass of the universe. Dark matter is a material that cannot be seen directly, but we know that dark matter exists because of the effect it has on the objects that we can observe.
Understanding dark matter is important in helping us understand the size, shape and future of the universe, and in helping us explain the formation and evolution of galaxies and clusters.
This event was one of over 100 worldwide events held on 31 October to mark ‘World Dark Matter Day’. The ‘Why The Dark Matters’ event consisted of interactive expert lectures to a local audience of several thousand, and a further live online audience of around 100,000. It included a live satellite link between China and the UK’s Boulby Underground Laboratory, which has a strong legacy in the field of dark matter research, and is where much of Dr Liu's research is based.

Edinburgh scientists are taking part in the most detailed survey of the Universe ever undertaken. The aim of the five-year programme is to shed light on Dark Energy – the mysterious force thought to be pushing galaxies apart and causing the Universe to expand at an accelerating rate.
Dark Energy Spectroscopic Instrument
The Dark Energy Spectroscopic Instrument (DESI) has been designed and built by an international collaboration of scientists. It is taking part in its first fully functioning experiment, from its position atop the Mayall Telescope in Arizona.
One of DESI’s crucial components is its array of 5,000 robotic fibre-optic eyes that swivel in a choreographed dance, each focusing on a distant galaxy. In perfect sky conditions they will enable the instrument to measure the light of 5,000 galaxies in around 20 minutes.
The instrument’s near complete range of components is designed to point automatically at preselected galaxies, gather their light and then split it into various bands of colour. This will precisely map their distance from Earth and gauge how quickly the galaxies are moving away from us.
When formal observations begin in 2020, DESI will peer deeply into the Universe’s infancy and early development – up to 11 billion years ago – to create the most detailed 3-D map of the Universe ever produced.
Over its five year run, DESI will repeatedly map the distance to 35 million galaxies and 2.4 million star-like quasars. The mapping of the galaxies will teach scientists more about Dark Energy and quasars, which are among the brightest objects in the sky.
Overall, it will provide precise measurements of the Universe’s expansion rate and tell scientists exactly how this rate has varied over time. This could bring them closer to figuring out the mechanism for the acceleration of the expansion.
Global alliance
An international team of more than 500 researchers and 75 institutions including Edinburgh’s Institute for Astronomy have collaborated on the project for more than a decade.
Edinburgh’s expertise stems from the Institute’s work on the influential Two-degree Field Galaxy Redshift Survey (2dFGRS) for which the School of Physics & Astronomy's Professor John Peacock was jointly awarded the prestigious Shaw Prize for Astronomy in 2014.
Professor Peacock commented:
DESI will define a new state of the art for studying the large-scale structure of the Universe. This has always been a scientific area in which the UK has been strong, and we’re very happy to be part of this wonderful project.
