Director of Supergen Bioenergy Hub, Professor Patricia Thornley


Industry experts and university researchers have joined together to ask the government to address the climate impact of organic, carbon-based chemicals.


While demand for fossil fuels as energy is expected to fall in the coming decades, the

petrochemicals sector is set to grow significantly according to experts and is set out in a 2018 report by the International Energy Agency.


Members of the Supergen Bioenergy Hub which is based at Aston University and the Biomass Biorefinery Network believe the issue has yet to receive proper attention and is calling for a strategy that addresses this key component of our greenhouse gas emissions. They want a move to a more circular economy, managing supply and demand levels and transitioning away from fossil feedstocks which are raw materials required for some industrial processes.


In their paper Carbon for chemicals How can biomass contribute to the defossilisation of the chemicals sector? they highlight that carbon-based chemicals cannot be decarbonised but can be defossilised through a transition to renewable carbon sources such as biomass, recycled carbon and carbon dioxide.


Many products in modern society contain carbon such as pharmaceuticals, plastics, textiles, food additives, cosmetics, and cleaning products. These chemicals are derived from fossil feedstocks, so they are classed as petrochemicals. As a result, they contribute to global greenhouse gas emissions and climate change. Carbon is embedded in organic chemical products and released when they break down at end-of-life, for example through incineration.


To address the emissions from carbon in chemicals and accelerate the development of bio-based chemicals, the group want a cross-party consensus to support a sustainable chemical system.


Director of Supergen Bioenergy Hub, Professor Patricia Thornley, said: “We need to consider the UK’s future feedstock and chemicals production and use, and how it relates to net zero, agriculture, environment, economy, trade, and just transition policy objectives. There are opportunities here for the UK to lead the way on sustainable chemical production, but we need to carefully plan a roadmap for the transition, that delivers opportunities around jobs and the economy as well as sustainable greenhouse gas reductions.


“There is a definite role for biomass here. But it is essential that any future use of biomass in the chemicals sector is underpinned by rigorous, trusted, and enforceable sustainability governance to build confidence, deliver sustainability benefits, and minimise negative impacts. That requires improvements in sustainability governance and regulation.


“We think there are real economic and trade opportunities by the UK accelerating sustainable chemicals. At the moment bio-based chemicals, and chemicals derived from other renewable carbon sources, are not being expanded in the UK because there are no explicit incentives that prioritise them over fossil-based production.”


The group argues that the UK has significant academic and industrial research expertise to underpin the development of sustainable bio-based products and could be a global leader in bio-based products and sustainability governance. They believe that to date little of this has manifested as UK-based scale-up and manufacturing, whilst there are numerous examples of UK-led research being scaled up elsewhere. The paper was delivered at a webinar on 7 August.

The Lost Girls of Autism – New book from Aston University emeritus professor Gina Rippon examines autism in women

The Lost Girls of Autism is published on 3 April 2025, coinciding with Autism Awareness Month in April In the book, Professor Rippon explores the ‘male’ history of autism, and why autism in women has been misunderstood and ignored Professor Rippon will give a free public lecture on the book at Aston University on 6 May 2025. Gina Rippon, professor emeritus of cognitive neuroimaging at Aston University Institute of Health and Neurodevelopment (IHN), has written a new book, entitled The Lost Girls of Autism. The book will be released on 3 April 2025, coinciding with Autism Acceptance Month in April. It has the subtitle ‘How Science Failed Autistic Women and the New Research that’s Changing the Story’. Historically, doctors believed that autism was a male condition, and simply did not look for it in girls and women. This has meant that autistic girls visiting a doctor have been misdiagnosed with anxiety, depression or personality disorders, or are missed altogether. Many women only discover they have the condition when they are much older, missing decades of support. In more recent years, it has become apparent that girls and women with autism have different traits and behaviours to boys and men, and are more likely to hide autistic traits to fit in – known as camouflaging. In The Lost Girls of Autism, Professor Rippon explores the emerging science of female autism, and examines why it has been systematically ignored and misunderstood for so long. Professor Rippon will give a free public lecture about her book on Tuesday 6 May 2025 at 18:00 BST at Aston Business School. Visit https://www.eventbrite.co.uk/e/the-lost-girls-of-autism-an-audience-with-author-gina-rippon-tickets-1304020734119 for more information and tickets. Copies of the book will be on sale at the event. Professor Rippon said: “This book reveals how a ‘male spotlight’ problem has biased many aspects of the autism story, from what autism is, to how we recognise it, and even how brain imagers like me search for answers. It shows how and why autistic women have been unrecognised, overlooked and unsupported. It shines a new light on how the story is changing and how we are now beginning to recognise the full spectrum of the autistic experience. It is for anyone with an interest in autism in all its presentations.”

How authorship language helped catch a domestic terrorist – new podcast

In the latest episode of Writing Wrongs, hosts Professor Tim Grant and Dr Nicci MacLeod interview Dr Isobelle Clarke to unravel a case where forensic linguistics helped track down and convict a dangerous individual. Episode three, Imposters Tending to the Wild with Dr Isobelle Clarke, dives into the chilling case of Nikolaos Karvounakis, a self-proclaimed anarchist who planted a viable explosive device in Princes Street Gardens, Edinburgh, in 2018. Karvounakis, a Greek national, evaded capture for years, hiding behind online anonymity and extremist rhetoric. However, forensic linguists stepped in to analyse his anonymous blog posts, revealing patterns in his language that ultimately helped Police Scotland link him to the crime. The case not only demonstrates how linguistic evidence can be a powerful forensic tool but also raises crucial questions about the role of language analysis in modern terrorism investigations. On 11 January 2018, a suspicious cardboard box was discovered in a public seating area in Edinburgh’s Princes Street Gardens. After a controlled explosion, investigators determined the device could have caused serious harm had it detonated. With no immediate leads, the investigation stalled - until an anonymous blog post surfaced, claiming responsibility for the attack. The post, written in both English and Spanish, was linked to an eco-anarchist group called Individualists Tending to the Wild, a Mexican-based extremist organisation advocating violent action against technological progress. Crucially, the post included an image of the bomb’s interior, a detail only the perpetrator or law enforcement could have known. Police Scotland sought the expertise of Professor Tim Grant, who analysed the text, producing a linguistic profile that suggested the writer was neither a native English nor Spanish speaker - but rather someone influenced by another language entirely. Two years later, police identified Nikolaos Karvounakis as a suspect. Using comparative authorship analysis, Professor Tim Grant compared his online writings - including song lyrics from his rock band - to the manifesto. By dissecting word patterns, grammatical structures and stylistic quirks, he established that Karvounakis was the likely author. This evidence -alongside forensic meteorology, which linked photos of clouds in Karvounakis’ blog posts to the same weather conditions on the day of the crime - was used to secure a warrant and seize computers containing known writings by Karvounakis. To eliminate inevitable bias that would result from having worked the case for more than two years, Professor Grant invited Dr Isabelle Clarke onto the case as an independent forensic linguist. Using a version of the General Imposters Method, a technique similar to a police lineup but for language, Dr Clarke confirmed that the writing style in the blog post was the closest to Karvounakis’ known writings. Police Scotland put the evidence in the case, including the linguistic evidence, to Karvounakis, and secured a guilty plea. In February 2022, Nikolaos Karvounakis was sentenced to over eight years in prison under the UK’s Terrorism Act. Tim Grant, professor of forensic linguistics at Aston University, said: “The case highlights the growing importance of forensic linguistics in solving crimes, particularly in an age where digital anonymity combines with extremist ideologies. “It also highlights the how different types of language analysis can assist as a case moves through different stages of investigation.” Dr Nicci MacLeod, deputy director of the Aston Institute for Forensic Linguistics, said: “This episode offers listeners a behind-the-scenes look at the forensic methods that expose deception, identify threats and ultimately bring criminals to justice.” Dr Isobelle Clarke, a lecturer in security and protection science at Lancaster University and one of the first graduates from the campus-based MA Forensic Linguistics programme at Aston University, said: “It was great to be back at Aston University talking about the Karvounakis case for the Writing Wrongs podcast. “It’s an interesting case to highlight, as it shows how different types of language analysis can help with police investigations.” Writing Wrongs is available on Spotify, Apple Podcasts and all major streaming platforms. Listeners are encouraged to subscribe, share and engage with the hosts by submitting their forensic linguistics questions. Whether it’s about this case or broader forensic linguistic techniques, Professor Grant and Dr MacLeod welcome inquiries from listeners.

Best-selling author Kate Summerscale joins Writing Wrongs to explore true crime and justice

The true crime podcast Writing Wrongs continues its exploration of language and justice with a special bonus episode featuring best-selling author and historian Kate Summerscale. Kate is an award-winning historian, journalist and best-selling author known for her meticulous research into historical true crime cases. Her book The Suspicions of Mr. Whicher won the Samuel Johnson Prize for Non-Fiction and was adapted into a major ITV drama. Her latest book, The Peep Show: The Murders at 10 Rillington Place, revisits the infamous Christie case, shedding new light on the victims’ lives, the social conditions of post-war Britain and the power of the press in shaping public perceptions of crime. In this episode, hosts Professor Tim Grant and Dr Nicci MacLeod explore a fresh perspective on the Rillington Place murders, the wrongful execution of Timothy Evans and how forensic linguistics has helped uncover the truth in criminal cases. Following on from the first episode of the series, which examined the Timothy Evans case and the origins of forensic linguistics, this conversation with Kate Summerscale provides fresh historical insights into one of Britain’s most infamous miscarriages of justice. The episode revisits the horrifying crimes of John Christie, whose calculated murders led to one of the most infamous miscarriages of justice in British history. The wrongful conviction and execution of Timothy Evans cast a long shadow over the UK’s legal system and played a pivotal role in the eventual abolition of the death penalty. Through expert discussion, the episode examines how Evans’ case became a turning point for criminal justice reform. The conversation also looks at the role of the media in shaping crime narratives. Sensationalist reporting during the Rillington Place murders fuelled public perceptions, sometimes distorting the truth in favour of dramatic storytelling. The episode draws comparisons between 1950s tabloid journalism and today’s true crime media, examining how crime reporting has evolved - and the ethical challenges it still faces. A deeply unsettling aspect of this case is its gendered nature. The majority of John Christie's victims were vulnerable women, many facing financial and social instability. The episode delves into how structural inequalities, from the lack of legal abortion to economic dependence, made women more susceptible to predatory figures like Christie, a pattern that remains relevant in crime analysis today. Finally, the episode scrutinises government complicity in covering up a miscarriage of justice. The Brabin Inquiry, launched in the 1960s, sought to reexamine Evans’ conviction but delivered a highly controversial conclusion, failing to fully exonerate him. The discussion highlights how political interests and legal reputation management influenced the case’s outcome, leading to Evans’ eventual posthumous pardon - but not a full legal exoneration. Tim Grant, professor of forensic linguistics at Aston University, said: “It was wonderful to have Kate on Writing Wrongs. “Her work challenges the traditional true crime narrative, shifting focus from the murderer to the victims and the broader social structures that allow such crimes to happen. “Her insights in this episode provide a fresh and deeply researched perspective on a case that still haunts British legal history.” Writing Wrongs is available on Spotify, Apple Podcasts and all major streaming platforms. Listeners are encouraged to subscribe, share and engage with the hosts by submitting their forensic linguistics questions. Whether it’s about this case or broader forensic linguistic techniques, Professor Grant and Dr MacLeod welcome inquiries from listeners.
