Professor Sinead Farrington who was honoured as Physical Sciences and Engineering Laureate (first place) in the 2021 Blavatnik Awards for Young Scientists in the United Kingdom awards ceremony on 25th October in London.
The Blavatnik Awards are administered by the New York Academy of Sciences, of which Prof. Farrington is now a life-member. These awards are the largest unrestricted UK science prize, with an award of $100,000 for each laureate, and $30,000 for each of two additional finalists in the three categories: physical sciences and engineering, chemistry and life sciences.
Professor Farrington was presented the Physical Sciences and Engineering Laureate’s medal at a banquet hosted by Sir Leonard Blavatnik and the Blavatnik Family Foundation, attended by prominent scientists and policy-makers at which she gave a talk on her research, at Banqueting Hall in Whitehall, London. An open public symposium was held the following day where Professor Farrington and her fellow laureates and finalists spoke on their subjects. Professor Farrington and the Life Sciences Laureate, also from Edinburgh - Professor Steven Brusatte from Geosciences - took part in a discussion panel with BBC Science correspondent, Victoria Gill.
Professor Farrington is based in the School’s Particle Physics Experiment research group where she holds an European Research Council (ERC) consolidator grant funding her team of postdocs and PhD students searching for Beyond Standard Model particles. She leads the UK collaboration on the ATLAS experiment at the Large Hadron Collider at CERN. She received the Blavatnik Award in recognition of her leadership of an international working group at CERN that has improved our understanding of the properties of the Higgs boson, and the development of key trigger and analysis techniques for the exploitation of Large Hadron Collider data and searches for new physics beyond the Standard Model.
Prof Farrington commented:
High energy physics is a collaborative endeavour involving very talented individuals from around the world, working together to build machines on a grand scale, and to analyse the data they generate to help us understand how the universe works at its deepest levels. I am privileged to have been able to contribute to this endeavour and to help provide some pieces of nature’s great puzzle, and am honoured to have received this Blavatnik Award.
Start-up business Dyneval Ltd, which was founded by soft matter physicists, has secured funding to establish a quality control standard that will benefit the livestock production chain.
Funding
Dyneval is delighted to announce that it has secured total funding of over £1.8M to establish a new quality control standard for semen analysis that will benefit users across the livestock production chain.
As part of the funding round, Dyneval secured a £575K grant from InnovateUK under the Transforming Food Production Series A Investor Partnership. Securing lead investor support from Jim Dobson of Cottagequinn Enterprises Ltd within the Series A Partnership, and through a collaborative funding investment round led by Kelvin Capital and supported by Par Equity, Gabriel Investments and Scottish Enterprise, a further £1.293m of equity investment was raised.
Entrepreneurial effort
Dyneval was established by Dr Tiffany Wood and Dr Vincent Martinez in April 2020 to offer innovative technology for the precise measurement of semen quality in order to improve the profitability and sustainability of farming. Tiffany and Vincent have a background in the physics of complex fluids, which can be described as ‘liquids with bits in them’.
The challenge
Over the past 40 years, conception rates in cattle have fallen by 20% and this is costing the average UK dairy farmer over £37k each year. To assess semen quality on farm, vets rely on visual assessment using an optical microscope and data has shown that veterinary assessment can vary by as much as 40% so that vets err on the side of caution when advising farmers. The Dynescan, from Dyneval, is a portable instrument that provides reliable measurements of semen quality on the farm so that damaged or inferior quality semen can be discarded to ensure that only top quality semen is used for reproduction. This will save many cows from returning for insemination, improving their welfare while improving the operational efficiency of farms. Predictions indicate that if conception rates can be elevated by 27%, the carbon footprint of farming could be reduced by up to 20% [Garnsworthy, Animal Feed Science and Technology, 112, 2004]. Improving the sustainability of farming is a win-win-win: it helps farmers, improves animal welfare and is better for the environment.
Future plans
Next month, Dyneval will move address to the Roslin Innovation Centre based at the University of Edinburgh’s Easter Bush Campus and within a cluster of the highest concentration of animal related science expertise in Europe.
New results from the MicroBooNE experiment deal a blow to a theoretical particle known as the sterile neutrino.
No sign of the sterile neutrino
For more than two decades, this proposed fourth neutrino has remained a promising explanation for anomalies seen in earlier physics experiments. Finding a new particle would be a major discovery and a radical shift in our understanding of the universe.
However, four complementary analyses released by the international MicroBooNE collaboration all show the same thing: no sign of the sterile neutrino. Instead, the results align with the Standard Model of Particle Physics, scientists’ best theory of how the universe works. The data is consistent with what the Standard Model predicts: three kinds of neutrinos - no more, no less.
Neutrino detector
MicroBooNE is a 170-ton neutrino detector at the U.S. Department of Energy’s Fermi National Accelerator Laboratory, which is roughly the size of a school bus and has operated since 2015. The international experiment has close to 200 collaborators from 36 institutions in five countries, including the School’s Dr Andrzej Szelc, who is the MicroBooNE UK Principal Investigator (PI). They used cutting-edge technology to record spectacularly precise 3D images of neutrino events and examine particle interactions in detail—a much-needed probe into the subatomic world.
What are neutrinos?
Neutrinos are one of the fundamental particles in nature. They’re neutral, incredibly tiny, and the most abundant particle with mass in our universe—though they rarely interact with other matter. They’re also particularly intriguing to physicists, with a number of unanswered questions surrounding them. These puzzles include why their masses are so vanishingly small and whether they are responsible for matter's dominance over antimatter in our universe. This makes neutrinos a unique window into exploring how the universe works at the smallest scales.
First hints of sterile neutrinos
Neutrinos come in three known types—the electron, muon and tau neutrino—and can switch between these flavors in a particular way as they travel. This phenomenon is called “neutrino oscillation.” Scientists can use their knowledge of oscillations to predict how many neutrinos of any kind they expect to see when measuring them at various distances from their source.
Neutrinos are produced by many sources, including the sun, the atmosphere, nuclear reactors and particle accelerators. Starting around two decades ago, data from two particle beam experiments threw researchers for a loop as they saw more particle events than calculations predicted. These strange neutrino beam results were followed by reports of missing electron neutrinos from radioactive sources and reactor neutrino experiments.
Sterile neutrinos emerged as a popular candidate to explain these odd results. While neutrinos are already tricky to detect, the proposed sterile neutrino would be even more elusive, responding only to the force of gravity. But because neutrinos flit between the different types, a sterile neutrino could impact the way neutrinos oscillate, leaving its signature in the data.
Next steps in neutrino research
MicroBooNE’s new results are an exciting turning point in neutrino research. With sterile neutrinos further disfavored as the explanation for anomalies spotted in neutrino data, scientists are investigating other possibilities. These include things as intriguing as light created by other processes during neutrino collisions or as exotic as dark matter, unexplained physics related to the Higgs boson, or other physics beyond the Standard Model.

Quantum Mechanics is a textbook written by two members in the School of Physics & Astronomy. Published by Cambridge University Press, the book is going to be available on Thursday 21 October.
Quantum Mechanics is a textbook written by two members in the School of Physics & Astronomy, Prof. Arjun Berera and Prof. Luigi Del Debbio.
This book presents a modern coverage of Quantum Mechanics. Beginning with a detailed introduction to quantum states and Dirac notation, the book includes - among others - a chapter on symmetries and groups, important components of current research; and a comprehensive chapter on quantum entanglement. This subject is rapidly growing not just in the field of physics but also in communication, computing and encryption. To date, however, there have been limited sources for undergraduate students to get a basic introduction to the subject. The various exercises in the text expand upon key concepts and further develop students' understanding.
I had no idea how much work would be needed to turn a bunch of lecture notes into a proper book! Without the curiosity of the students, the patience of the editor and Arjun’s support, I would have given up long ago. I am very happy to have a book that introduces Quantum Mechanics in a format that aims to be suitable for lectures. Writing a textbook, as opposed to a comprehensive treaty on Quantum Mechanics, was our main challenge (Prof. Luigi Del Debbio)
The early motivation for writing this book was that both authors were - and still are - teaching Principles of Quantum Mechanics in the School of Physics & Astronomy, a course taken by Mathematical and Theoretical Physics students (the second semester of this course is also the Quantum Physics course). The lectures from this course provided an initial baseline for the book. The project has been developing for over seven years and has expanded from the lectures of the course into what is now this textbook
At the onset of starting work on this book, I felt there was a missing element in undergraduate quantum mechanics courses: namely a comprehensive treatment of quantum entanglement that could be covered in a 2-3 week module. I had formed a set of lectures on this subject for the second semester of the Principles of Quantum Mechanics course, which I thought were fairly successful and the input and interest from the students was helpful in making improvements. Those lectures were the basic material for the chapter on quantum entanglement in the textbook. It was a lot of work to produce this chapter, but I hope readers find it helpful. This chapter had to fit coherently with all others to produce a textbook. As Luigi and I had taught Principles of Quantum Mechanics for many years, it made it very easy to have a coordinated effort in writing this textbook, especially since we both were supportive to each other in this work (Prof. Arjun Berera).
The Astronomer Royal for Scotland, Professor Catherine Heymans, has officially opened Aberdeen Science Centre following its £6million redevelopment.
Aberdeen Science Centre reopened to the public last November after a major project to create an aspirational science centre which reflects the STEM priorities for both industry and education. More than 60 new interactive exhibits over two floors now await visitors.
Around 100 invited guests attended the official opening, where Professor Heymans unveiled a commemorative plaque to mark the centre’s transformation.
An astrophysicist and a world-leading expert on the physics of the dark universe, Professor Heymans became the first woman to be named Astronomer Royal for Scotland earlier this year. Accepting the almost 200-year-old honorary title, she said she wants to use it to encourage people to develop passion for science and promote Scotland internationally as a world-leading centre for science.
Professor Heymans said:
It is a great honour to join Aberdeen Science Centre in celebration of its reopening. A fantastic visitor attraction with outstanding interactive hands-on exhibits, Aberdeen Science Centre provides the perfect place for curious young minds to have fun exploring the wonderful world of science and technology.
The centre’s exhibits are aimed at all ages and are themed into six zones: Energy; Space; Life Sciences; Make It, Test It; and a dedicated area for the under-6s, as well as the Shell Learning Zone, where science, technology, engineering and mathematics (STEM) are brought to life. New exhibits include RoboThespian, a chatty humanoid robot sponsored by the centre’s Digital Futures Partner, Equinor, and The OPITO Theatre of Energy – the UK’s first immersive experience of its kind.
Bryan Snelling, Chief Executive of Aberdeen Science Centre, said:
We are delighted to welcome Professor Heymans and our invited special guests to mark the official opening of Aberdeen Science Centre following its fantastic redevelopment. This is a celebration of all the work that has gone into redeveloping the centre to transform it into a modern visitor attraction which showcases STEM innovations through educational and fun exhibits and events.

Dr Maxwell T. Hansen has been awarded the 2021 Kenneth G. Wilson Award for Excellence in Lattice Field Theory.
Since its inception in 2011, the annual award has recognised physicists who have made recent, outstanding contributions to lattice field theory – the study of quantum field theories on discretised spacetime (the lattice), amenable to simulation by computers.
The award was presented at the annual Lattice International Conference.
Max is a UKRI Future Leaders Fellow within the Institute for Particle and Nuclear Physics. His research focuses on extending the reach of numerical lattice calculations to extract more complicated observables governed by the strong force of particle physics and, more broadly, predictions of the full Standard Model. Specifically he has made significant developments in methods for extracting multi-particle scattering amplitudes, based in techniques that use the finite system size of the simulation as a useful probe of the interactions (rather than an unwanted artifact).
The award is named after Nobel Laureate Kenneth Wilson (1936–2013), who formulated lattice gauge theory in 1974, thereby improving our theoretical knowledge of non-perturbative quantum field theories and eventually permitting such theories to be studied numerically using world class computers.

Prof Aliotta receives the Giuseppe Occhialini Medal and Prize in recognition of her work in nuclear astrophysics.
Giuseppe Occhialini Medal and Prize
The Giuseppe Occhialini Medal and Prize is awarded jointly by the Institute of Physics and the Italian Physical Society for distinguished work by a physicist based in Italy or the UK/Ireland.
Prof Marialuisa Aliotta received this award for her major contributions to nuclear astrophysics experiments, in particular to the study of key hydrogen-burning reactions relevant to quiescent stellar evolution and nucleosynthesis, in the framework of the international LUNA experiments at the Laboratori Nazionali del Gran Sasso, INFN (Istituto Nazionale di Fisica Nucleare).
Investigating the nuclear reactions in stars
Her research interests focus on experimental nuclear astrophysics, specifically on the investigation of nuclear reactions that occur in stars and govern their lifetime and evolution. These reactions are also responsible for the creation of new chemical elements both in quiescent stars like our sun and in explosive scenarios like novae, supernovae, and X-ray bursts.
Quiescent stellar evolution involves reactions mainly between stable nuclei at energies well below the Coulomb barrier of the interacting species. Their experimental investigation in a terrestrial laboratory is severely hampered by the background induced by the cosmic rays in the detection devices. Thus, a unique approach consists in carrying out measurements underground, where the background induced by cosmic rays is suppressed by orders of magnitude. Over the last ten years, Marialuisa’s research has been conducted at the world leading Laboratory for Underground Nuclear Astrophysics (LUNA) at the INFN Laboratory Nazionali del Gran Sasso (Italy). Prior to joining the LUNA Collaboration in 2010, Prof. Aliotta proposed and performed experiments at Radioactive Ion Beam facilities (TRIUMF, GANIL, CERN) mainly to study (α,p) reactions on unstable nuclei, many of which are crucial to drive explosive scenarios such as X-ray bursts. These measurements are also difficult to perform because of limitations in radioactive ion beam species and intensities. New opportunities are now opening up with the use of storage rings such as CRYRING at GSI (Germany).
Prof Aliotta commented:
I’m delighted to have received the Giuseppe Occhialini Medal and Prize for 2021. As it is often the case, awards to individuals are never entirely their own. So, aside from my personal recognition, the prize is also a recognition of the outstanding work of the entire LUNA Collaboration. My heartfelt gratitude goes to all my colleagues at LUNA and in particular to Dr Carlo Bruno and Prof Thomas Davinson for their extraordinary contributions over the years.
Congratulations to Dr Dominique Laniel who has been awarded a UK Research and Innovation (UKRI) Future Leaders Fellowship, and will be joining the School of Physics and Astronomy and the Centre for Science at Extreme Conditions (CSEC).
Fellowship scheme
The UKRI Future Leaders Fellowships have been instigated to ensure the strong supply of talented individuals needed for a vibrant environment for research and innovation in the UK.
In this round, a total of 13 pioneering researchers, tech entrepreneurs, business leaders and innovators across different sectors and disciplines in Scotland will benefit from a £16.5 million cash boost to convert their innovative ideas to transformational products and services.
Nitrogen-based technological materials
Dr. Dominique Laniel's research aims to synthesise next-generation high energy density and superhard nitrogen-based technological materials employing extreme pressure and temperature conditions—up to 1,500,000 times the atmospheric pressure and 5000 K. His research will also expand our fundamental understanding of matter at extreme conditions, essential for modelling planetary bodies and providing benchmarks for theoretical calculations.
Dominique obtained his Master's degree in Condensed Matter Physics at the University of Ottawa, Canada, followed by a PhD in Solid State Physics and Chemistry from the Sorbonnes University, France. He then pursued his research as an Alexander von Humboldt Fellow, and later through a Deutsche Forschungsgemeinschaft grant, at the University of Bayreuth, Germany, in the Laboratory of Crystallography - Materials Physics and Technology at Extreme Conditions.
UK project processing massive data stream from the Vera C. Rubin Observatory in Chile will take inventory of the Universe.
How it will work
The Vera C. Rubin Observatory in Chile will carry out the Legacy Survey of Space and Time (LSST) by constantly surveying the southern sky over a period of 10 years. The Observatory consists of an 8-metre telescope, the largest digital camera ever constructed with 189 sensors totalling 3.2 gigapixels, a complex data processing system, and an online education platform.
The survey will produce an image every minute, and every object that is variable, transient or moving will be catalogued and a constant data stream of these alerts will be produced.
It will impact every area in astronomy and will revolutionise the capability of astronomers to scan the sky for distant cosmic explosions, hungry black holes, the nearest earth-hazardous asteroids and the search for distant bodies and dwarf planets in the outer solar system.
The role of the UK
This work is part of UK’s Lasair project which has been selected as an official LSST community alert broker and will receive the full Rubin alert stream. The University of Edinburgh and Queen’s University Belfast have been partnering, with funding from STFC (Science and Technology Facilities Council), to build a community broker that will provide a user friendly and scientifically powerful platform for world-wide users to exploit this information-rich data stream.
They built Lasair (which is Gaelic for "flame" or "flash"), the working prototype, which demonstrates how scientists across the world can scientifically exploit this massive data stream. The Rubin Observatory can support only a fixed number of full data streams, given their size and daily rate, and issued a call for proposals from the world-wide community.
Prof Stephen Smartt from the Queen's University Belfast said:
"Our selection as a community broker is endorsement of the work we have been doing over the last 3 - 5 years, showing that the UK has the technical and computing expertise to allow the world to exploit the LSST data. Rubin will be an enormous leap forward in scientific capability - the sensitivity, precision of measurement, and spectral information is unprecedented. But science will come from being able to understand and extract information from this stream."
Dr Roy Williams from the School of Physics and Astronomy’s Institute for Astronomy, and one of the lead developers and architects of Lasair said:
"There is now a deluge of data as sensors of all kinds proliferate. Electric grids deliver logging information at dizzying rates and bridges have internet-connected stress monitors, everywhere in modern society more messages are being produced. The difficulty is discerning what is critical and urgent from the irrelevant and ordinary. We are taking the lead in building a system so UK astronomers can get precisely what they are looking for."
What’s next?
The UK team have demonstrated a successful prototype, running on a data stream from the Zwicky Transient Facility (ZTF). The ZTF is a much smaller telescope based in California that produces a stream of astronomical alerts in similar format to that which will come from LSST.
The LSST data stream will be a factor 30 larger than that from ZTF and the Lasair team are now developing their technology to cope with the richer data flow. Lasair matches the alerts against every astronomical object that has ever been catalogued in the sky, in a giant database, and classifies the alerts based on the what we know about that region of sky across the full electromagnetic spectrum.
The team are developing novel database and data streaming techniques over the next two years to be ready for science data from Rubin in early 2024. The full telescope commissioning in Chile is planned to begin in 2023 and the Lasair team are working to be ready to accept the data tsunami that will run for 10 years.
