In the vast expanse of the world’s oceans, a transformation is underway.

The international shipping sector, made up of thousands of massive cargo ships laden with many of the goods we buy, emits carbon dioxide (CO₂) roughly equivalent to the entire country of .

Our emphasises the need for immediate action. Reducing shipping emissions by 34% by 2030 is necessary to stay on course with the Paris Agreement’s 1.5°C goal. But with low-carbon fuel pipelines unlikely to be at the necessary scale until at least the 2030s, how can the industry meet its short-term target?

Enter a new solution with ancient origins: sails. Not the billowing canvases of centuries past but high-tech systems capable of harnessing renewable wind energy to supplement the propulsion from a ship’s engine.

A number of advanced sail designs are gaining the attention of shipping firms. Two contenders include Flettner rotors, cylinders that spin to generate propulsion, and “wingsails”, which resemble aeroplane wings and are derived from designs used in yacht racing.

Wind propulsion allows ships to use less fuel and so emit less greenhouse gas. However, in our , we found that the real opportunity to slash emissions from shipping this decade lies in combining sails with optimal routes plotted by satellite navigation systems.

An old idea with new technology

Optimised routing is a familiar concept to most of us. You’ll have used it by typing a destination into Google Maps and allowing its algorithms to calculate the quickest way for you to arrive at your destination.

The process is similar for ships. But instead of finding the quickest journey, the software models the ship’s performance in water to calculate routes and speeds that minimise fuel use.

With optimised routing and sails, ships can deviate from their standard course to seek out favourable winds. The ship may travel a longer distance but the extra power gained by the sails limits the ship’s fuel consumption and reduces the total emissions over the full journey. The software only suggests routes that guarantee the same arrival time, keeping the ship to its original schedule.

We used a computer model simulation of a cargo vessel with four sails, each taller than Brazil’s Christ the Redeemer statue at 35 meters high. By calculating the fuel consumption of this large bulk carrier ship on over 100,000 journeys spanning four years and covering 14 shipping routes worldwide, we found that sails can cut annual carbon emissions by around 10%.

The true promise of sails unfolds when optimal routing is used, increasing annual emission cuts to 17%.

Routes with ideal wind conditions have even greater potential. The most promising are typically those far from the equator, such as transatlantic and transpacific crossings, where strong winds can fill large sails. By taking advantage of wind patterns moving across the ocean on these routes, sails and optimised routing can cut annual emissions by over 30%.

Take the journey between the UK and the US as an example. A ship setting out on this voyage will typically experience strong headwinds which generate drag and push the ship backwards, meaning more fuel must be burned to maintain the same forward momentum. But by using sails and optimised routing software on this crossing, ships can avoid these headwinds and steer into more favourable winds.

A cargo vessel with two cylinders rising from the deck.Flettner rotors are smooth cylinders with discs that spin as wind passes at right angles across it. Norsepower,

On the return journey, the ship would typically experience strong winds from behind and the side, which would fill the sails and push the ship on. With optimised routing software the ship can find even stronger winds and fine-tune its direction for the sails to maximise propulsion.

Keeping the 1.5°C target afloat

The International Maritime Organization (the UN agency responsible for environmental regulation in shipping) has a of cutting greenhouse gas emissions by 20%-30% by 2030. The Paris Agreement’s 1.5°C target .

Our research shows that cuts to CO₂ of this magnitude are possible this decade using wind propulsion and optimised routing on promising routes. Achieving this will oblige the shipping industry to deploy existing technologies and practices and shift its focus from fuel alone, as will take longer to develop.

As we sail further into the 21st century, our research delivers a clear message to the shipping industry: substantial carbon reductions are feasible this decade. Here is an old idea, one that integrates technology with tradition, that can steer international shipping towards its climate goals.

Engineers at 51 have built and flown the world’s largest quadcopter drone.

The drone, made from a cardboard-like material called foamboard, measures 6.4m (21 ft) corner to corner and weighs 24.5kg – 0.5kg less than the weight limit set by the Civil Aviation Authority.

The innovative design of the drone, dubbed the Giant Foamboard Quadcopter (GFQ), means it is unlike any other in existence. The four arms are formed of a series of hollow box structures and can be easily removed for transportation. There is no record of a purpose-built uncrewed quadcopter (four rotors) of any weight class which is larger than the 51 vehicle as of the time of writing.

The project started as a curiosity-driven venture to inspire students’ creativity in design by utilising a suitable alternative low-cost material for lightweight aerospace structures that is more environmentally friendly than the usual carbon fibre.

Unlike carbon fibre, low-density sheet materials can be highly recyclable, or even compostable. The researchers hope this demonstration will inspire the next generation of designers to think about sustainability from a completely new perspective.

Dan Koning, a research engineer at 51, who led the design and build of the vehicle, said: “Foamboard is an interesting material to work with, used in the right way we can create complex aerospace structures where every component is designed to be only as strong as it needs to be - there is no room for over-engineering here.

“Thanks to this design discipline and after extensive background research, we can say with confidence that we have built the largest quadcopter drone in the world.”

Whilst this drone was developed purely as a proof-of-concept exercise, future iterations of this vehicle type could be designed to carry large payloads over short distances or used as a drone ‘mothership’ in air-to-air docking experiments.

The quadcopter was built from sheets of 5mm thick foamboard, which has a foam core and paper skin. The sheets were laser cut to size and assembled into the 3D structure by hand using only hot melt glue.

Josh Bixler, world renowned YouTuber and innovator in remote-controlled aviation is the President of , the company that makes the foamboard used in the GFQ.

Commenting on the work, Josh said: “So many times aircraft with advanced features are made of costly materials and we truly believe they don’t have to be. Seeing engineers push the limits in such an approachable, yet extravagant way was inspirational and showed that they were truly thinking outside of the box.”

GFQ is powered by four electric motors running off a 50-volt battery pack. It also has an on-board flight control system and can fly autonomously.

The first flight took place on 5 July 2023 inside the main hangar at the Snowdonia Aerospace Centre during the CASCADE Collaboration Workshop Week where teams from various universities around the UK come together to demonstrate their latest research tech and brainstorm innovation.

Kieran Wood, a Lecturer of Aerospace Systems at 51, who piloted the vehicle, said: “The first moments of flight are the make-or-break point for these types of multi-copter drones. There are many hundreds of things that you must get right. If everything has been designed and built well, we expect success, but any problems will become very apparent in a rapid unscheduled disassembly on the first take-off.”

The project builds on the previous success of an equally  Following this, a student society was created at the University specifically to focus on developing lightweight, large scale foamboard Unmanned Aerial Vehicles (UAVs).

Over the last year, a team of undergraduates helped build and test various critical sub-components of the structure.

Bill Crowther, a Professor of Aerospace Engineering at 51, said: “Working with foamboard provides a unique learning opportunity for students to experiment with innovative structural designs. Although the material is strong for its weight, it requires significant engineering skill to exploit its structural potential. Ultimately, with this design you are holding up 25kg of aircraft with just a few strategically placed pieces of paper - that’s the art of the possible.”

The team are now looking to optimise the design of the Giant Foamboard Quadcopter further.

Dan Koning added: “The lessons we’ve learned from this pathfinder vehicle should help us add a few more metres to the next one. But to go 50% bigger, you’ve got to get 100% smarter.”

The first Stephen Hawking Fellows, announced today, will continue Professor Stephen Hawking’s legacy by furthering our understanding of the universe and communicating the wonders of science to the public.

Two of the nine fellows are from 51, Dr Danai Antonopoulou and Dr Stefan Schact, who has recently joined from Cornell University.

They will tackle major scientific questions such as the nature of the early universe and dark matter and whether string theory really is a ‘theory of everything’, engaging with the public through stand-up comedy, art and music.

The Stephen Hawking Fellowships were launched by (UKRI), working with the Hawking family, in recognition of Stephen Hawking’s exceptional contributions to scientific knowledge and popularisation of science.

Professor Stephen Hawking’s children, Lucy, Robert and Tim Hawking, said: “We are proud to be associated with this initiative, which builds on the legacy of our father by supporting research into these areas of science.

“One of his greatest achievements was opening up even the most complex scientific breakthroughs to the wider world and we hope that these Fellows are able to continue that important mission by inspiring people from all walks of life in the wonders of science.”

Dr Schacht aims to build on last year’s observation of the unique phenomenon of matter-antimatter asymmetry in a form of particle called the D0 meson, to take us one step closer to answering our big questions about the fundamental laws of nature.

He plans to engage the wider public by establishing a programme for particle physics at the , an annual music, science and art festival at the Jodrell Bank Observatory site.

Based at the , Dr Antonopoulou will advance our knowledge of neutron stars and their unusual physical properties, such as superfluidity and superconductivity and the nature of extremely dense matter.

A detailed public engagement programme aimed at school children and students, and targeting underrepresented groups, will aim to inspire them about astrophysics and science in general.

UKRI will support up to 50 postdoctoral scientists through the Stephen Hawking Fellowships scheme, with further calls to be launched in due course.

UK Research and Innovation Chief Executive, Professor Sir Mark Walport, said: “Professor Stephen Hawking pushed forward the boundaries of human knowledge, both through his research which transformed our understanding of the universe and his rare talent for communication.

“The Fellows announced today will continue his legacy, pushing the boundaries of knowledge and inspiring the public with the value and beauty of science.”

Each fellowship provides up to four years’ funding, dependent on the nature of the proposed research, for fellows with a strong passion for curiosity-driven science, who seek to challenge current assumptions and inspire the public through their work.

Fellows will be supported with training in public engagement and scientific communication to help them inspire a wider audience to explore complex scientific ideas, continuing Professor Hawking’s legacy of bringing science into popular culture.

The Stephen Hawking Fellowships are delivered by UKRI’s Engineering and Physical Sciences Research Council and Science and Technology Facilities Council.

Business Secretary Alok Sharma and Education Secretary Gavin Williamson announced the funding as part of a major investment which also funding to improve and boost uptake of science subjects at school.

Education Secretary Gavin Williamson said: “Making sure that the next generation has the scientific skills to meet the world’s needs – from developing green technologies to curing illnesses – couldn’t be more important.

“That’s why we continue to invest in science programmes in our schools and ensure that anyone, regardless of their background, can participate.

A black hole, ejecting material at close to the speed of light, has been observed using e-MERLIN, the UK’s radio telescope array based at Jodrell Bank Observatory.

A research team based at Oxford University used e-MERLIN, as well as the and MeerKAT telescopes based in the US and South Africa respectively, to track the ejecting material over a period of months.

The observations have allowed a deeper understanding into how black holes feed energy into their environment. Co-lead of the project, and author on the paper appearing in , Rob Fender said "We've been studying these kind of jets for over 20 years and never have we tracked them so beautifully over such a large distance.”

The group successfully tracked these ejections of this particular system, known as MAXI J1820+070, after it went into outburst in the summer of 2018. The extreme distances from the black hole and the final angular separation is among the largest seen from such systems.

The ejections are moving so fast that they appear to be moving faster than the speed of light – they are not, rather this is a phenomenon known as apparent superluminal motion.

Dr Rob Beswick, Head of e-MERLIN science operations at Jodrell Bank stated: “This work shows the power of world-class instruments such as e-MERLIN, MeerKAT and the VLA working in tandem.

“e-MERLIN’s unique combination of resolution, sensitivity and rapid response made it the perfect instrument for this sort of study”.

“Using our radio observations we were able to better estimate how much energy is contained in these ejections using a novel method for this type of system.” explains Joe Bright, DPhil student at Oxford University’s Department of Physics.

“Galactic black holes, such as MAXI J1820+070, are thought to be miniature versions of the supermassive black holes that are found at the centre of galaxies. The feedback from these black holes is thought to be a vital component regulating the growth of galaxies”.

Unique new antiviral treatment made using sugar /about/news/unique-new-antiviral-treatment-made-using-sugar/ /about/news/unique-new-antiviral-treatment-made-using-sugar/374984New antiviral materials made from sugar have been developed to destroy viruses on contact and may help in the fight against viral outbreaks.

New antiviral materials made from sugar have been developed to destroy viruses on contact and may help in the fight against viral outbreaks.

This new development from a collaborative team of international scientists shows promise for the treatment of herpes simplex (cold sore virus), respiratory syncytial virus, hepatitis C, HIV, and Zika virus to name a few. The team have demonstrated success treating a range of viruses in the lab – including respiratory infections to genital herpes.

The research is a result of a collaboration between scientists from 51, the  (UNIGE) and the  in Lausanne, Switzerland. Although at a very early stage of development, the broad spectrum activity of this new approach could also be effective against newly prevalent viral diseases such as the recent coronavirus outbreak.

So called ‘virucidal’ substances, such as bleach, are typically capable of destroying viruses on contact but are extremely toxic to humans and so cannot be taken or applied to the human body without causing severe harm. Developing virucides from sugar has allowed for the advent of a new type of antiviral drug, which destroys viruses yet is non-toxic to humans.

Current antiviral drugs work by inhibiting virus growth, but they are not always reliable as viruses can mutate and become resistant to these treatments.

Using modified sugar molecules the team showed that the outer shell of a virus can be disrupted, thereby destroying the infectious particles on contact, as oppose to simply restricting its growth. This new approach has also been shown to defend against drug resistance.

Publishing their work in the journal  the team showed that they successfully engineered new modified molecules using natural glucose derivatives, known as cyclodextrins. The molecules attract viruses before breaking them down on contact, destroying the virus and fighting the infection.

Dr Samuel Jones, from 51 and a member of the  for Advanced Materials, jointly led the pioneering research with Dr Valeria Cagno from the University of Geneva. “We have successfully engineered a new molecule, which is a modified sugar that shows broad-spectrum antiviral properties. The antiviral mechanism is virucidal meaning that viruses struggle to develop resistance. As this is a new type of antiviral and one of the first to ever show broad-spectrum efficacy, it has potential to be a game changer in treating viral infections.” said Sam.

Professor Caroline Tapparel from the University of Geneva and Prof Francesco Stellacci from EPFL were both also senior authors of the study. Prof Tapparel declared: “We developed a powerful molecule able to work against very different viruses, therefore, we think this could be game changing also for emerging infections.”

The molecule is patented and a spin-out company is being set up to continue pushing this new antiviral towards real-world use. With further testing the treatment could find a use in creams, ointments and nasal sprays or other similar treatments for viral infections. This exciting new material can work to break down multiple viruses making for cost-effective new treatments even for resistant viruses.

The paper, Modified Cyclodextrins as Broad-spectrum Antivirals, by Jones et al is published in Science Advances.

Advanced materials research at 51 has demonstrated a comprehensive picture of the evolution of damage in braided textile composites for the first time. This could lead the way to new design and implementation possibilities for next-generation aerospace engineers.

High-specification composite materials can be precisely engineered to suit applications with confidence thanks to new imaging techniques. Textile composites in particular offer great potential in creating light-weight damage-tolerant structures. However, their uptake in the high value manufacturing sector has been inhibited by lack of adequate design and material performance data.

As a result of new research published today in the , braided textile composites could be designed with confidence for applications ranging from, aerospace and automotive drive shafts, to sporting equipment such as hockey sticks. Braiding technology had a humble beginning in the textile industry for making such items as shoe laces. Today, the integration of robotics and advanced industrial systems has propelled this technology into the high value manufacturing domain in sectors such as, aerospace, automotive and energy.

Now for the first time unique 3D imaging processes have provided real-time data of how carbon fibre composite tubes perform under structural loading, which provides a blueprint for maximising efficiency of materials used across industry.

The breakthrough research was led by a team from 51 and could prolong the lifespan of mechanical systems reliant on materials by definitively demonstrating load and stress points at which damage initiates and progresses from sub-critical to critical damage state.

By utilising real-time stress and damage tensor data along with developing bespoke composites design tools, future composites will be designed scientifically rather than through copycatting current designs which play to the requirements and weaknesses of metals currently used in industry.

The scientists leading this research are also prominent scientists from the soon-to-open , based at 51. One for the Royce is in performance and degradation to enable the design of new materials, systems and coatings for a range of applications including; energy, marine, aerospace and automotive.

Professor , Chief Scientist of the Royce, said: “In-situ X-ray imaging has allowed us to shed light on the 3D nature of the initiation and propagation of damage mechanisms in composite tubes for the first time”.

The materials tested and examined in this work were braided carbon fibre composite tubes which are fabricated by braiding the fibre tows into a continuous interlaced helices. Recent advances show there is considerable scope for tailoring braided structure to suit specific service requirements. This flexibility also challenges the design and manufacturing process of braided composites. This means the way engineers develop applications can start to be seen in a different light for the next generations of aircraft for example.

Prof Prasad Potluri, Research Director of the said: “This is a fantastic opportunity to push the advanced braiding technology through the technology readiness levels with the aid of the in situ X-ray imaging facility at the Henry Royce Institute”.

Bite marks in fossils reveal demise of our early relatives /about/news/bite-marks-in-fossils-reveal-demise-of-our-early-relatives/ /about/news/bite-marks-in-fossils-reveal-demise-of-our-early-relatives/371249New fossil data show that our fishy ancestors may have risen to dominance by becoming predators of their ancient jawless cousins.

New fossil data show that our fishy ancestors may have risen to dominance by becoming predators of their ancient jawless cousins.

Palaeontologists at 51 have revealed the changing pattern in bite marks in fossil record of early vertebrates through time, and unlocked the circumstances of our own evolution.

Almost all modern vertebrates alive today are jawed vertebrates, such as mammals, birds and sharks, but 400 million ago jawless fishes were the more diverse. Previous theories explaining the change from jawless to jawed vertebrate dominance included changing environment and climate, competition, or predation by giant sea scorpions. Now new research, published in , implicate another cause - jawed vertebrate predators.

By studying fossilised jawless fish, researchers from the University’s found that the frequency of bite marks increased through time, reaching a peak toward their extinction. The bite marks included, scratches, gouges and puncture marks in the skeleton of heterostracans, a group of jawless fish. Studying the patterns of these bite marks found that they were associated with the occurrence of jawed vertebrates; as such, our jawed relatives are implicated in the predation and demise of our jawless relatives, quite possibly contributing to their extinction.

“It is really exciting to be able to find direct evidence of an ecological interaction between fossil organisms from millions of years ago, especially one that helps us construct our own distant evolutionary history.” said Dr Robert Sansom.

Dr Emma Randle, currently a Scientific Associate at said: “Hetersotracan jawless fishes are really interesting as they are some of the first vertebrates to have bone - in the form of an armour-like ‘exoskeleton’. They thrived for many millions of years and came in a variety of beautiful forms often dominating the environments they were found within. Ultimately, like other varieties of armoured jawless vertebrates, they became extinct towards the end of the Devonian Period, but leave us a fossil record that helps us reconstruct the early evolutionary history of all vertebrates”

The researchers were able to unlock these evolutionary dynamics by studying over 2800 fossils, ranging over 50 million years, from the Silurian & Devonian periods (430 to 370 million years ago). The groups implicated as the main predators were placoderms, heavily armoured jawed vertebrates, and sarcopterygians, the lobe finned fish. The predators most associated with bite marks was Panderichthys, a key fossil for reconstructing the transition from sea to land, another important step in our own evolutionary history.
