Only two-thirds of UK airports have scrapped 100ml limit – full list of where you can fly from with unlimited liquids
IF you have summer plans, you need to check this list of 10 UK airports which now let holidaymakers take 2 litres on liquid in hand luggage. Only two-thirds of international UK airports have scrapped the strict cap - which now lets tourists effectively take as much as they want. 2 The new rule is due to the implementation of new 3D security scanners, which have allowed several airports to axe the meagre 100ml limit. The 15 international airports in the UK are set to scrap the pesky 100ml rule. But so far, only two thirds of that list have adopted the new policy. This leaves 10 airports that have permitted the higher levels of liquid on board. Tourists now arriving or departing from the UK can expect faster security checks as new 3D CT scanners start to replace older systems. The infamous 100ml rule is now set to go, but the current number of airports that have enacted this policy is still limited. Cutting-edge technology will allow passengers to carry a whopping two litres of of liquids in their hand luggage - without needing to remove them at security. The new airports which will have this groundbreaking rule are Birmingham, Bristol, Edinburgh, Gatwick, Leeds, Bradford, London City, Luton, Newcastle, Southend and Teesside. For travellers going through any of these airports, liquids in containers of up to 100ml are still allowed. There is no restriction on the amount of liquids that can be carried in these containers. How the Passport Card Can Help You Fly Without a Real ID Passengers can keep their liquids in their hand luggage - which removes the need for a separate plastic bag. Holidaygoers can also leave electronics such as laptops inside their bags thanks to the new technology. The latest state-of-the-art CT scanners have been engineered with much better 3D imaging technology. Traditional X-ray machines produce two-dimensional images. But these new breakthrough scanners create a more detailed, rotatable 3D visualisation of your baggage. The 100ml limit was rolled out in 2006. Ever since, travellers have gotten accustomed to not bringing more than that amount on holiday. They were also condemned to opening their bags up every time they entered security checkpoints. But these revolutionary scanners are set to change this. International airports such as Glasgow, Heathrow, Manchester, Stansted and Liverpool are still yet to remove the strict limit. 2

Kostya Trachenko obituary
My friend and scientific collaborator Kostya Trachenko, who has died aged 54 of cancer, was a theoretical physicist. He helped to reshape our understanding of liquids and revealed surprising connections between fundamental physical constants and the properties of everyday materials. Kostya's research findings, often in cooperation with his longtime collaborator Vadim Brazhkin, brought new clarity to the elusive behaviour of liquids. He developed a mathematical framework explaining how, under certain conditions, liquids behave like solids – such as when falling into water from a height. This insight led to a deeper understanding of how transverse sound waves propagate through liquids, and how these behaviours change with temperature. His work also explained the longstanding mystery of why the heat capacity of liquids often decreases with temperature, unlike in solids. In addition Kostya showed how ultra-thin liquid films behave more like solids when confined to surfaces, offering explanations for phenomena observed in nanotechnology and material science. In a separate line of inquiry, he made the striking discovery that fundamental constants – such as Planck's constant and the proton radius – govern limits in everyday materials, such as the lowest possible viscosity of fluids or the upper bound for the speed of sound in solids. Kostya was born in Ukraine to Oksana Trachencko, an English teacher, and her husband, Oleksiy Eigenson, an astronomer, later taking on his mother's surname. After attending high school in Lviv he studied physics at Lviv University, and on graduation he moved, in 1996, to the UK to study for a PhD at the University of Cambridge, completing it in 2001. He remained at Cambridge for postdoctoral work, contributing to the theory of inorganic crystals and materials for nuclear energy, before moving to Queen Mary University of London in 2010, where he became professor of physics. He led the PhD programme in the physical sciences there, reshaping it into something that was intellectually vibrant and modern. We met at a conference in Poland in 2017, and worked together trying to solve various conundrums connected with the rigidity of thin liquid layers under confinement and its scaling with film thickness. Kostya was published widely and wrote the monograph Theory of Liquids (2023), which he completed while already ill. He was an inspiring teacher and a spirited, generous friend, known for his loyalty, warmth and curiosity. He rarely stopped talking about physics. He is survived by his wife, Carmen, whom he married in 2013, their two children and his mother.
