• Subjecting contaminated water to speaker system helps eliminate microplastics

    Microplastics are released into the environment by cosmetics, clothing and industrial processes, or from larger plastic products as they break down naturally. The pollutants eventually find their way into rivers and oceans, posing problems for marine life. Filtering and removing the small particles from water is a difficult task, but acoustic waves may provide a solution. Researchers at the Sepuluh Nopember Institute of Technology in Surabaya, Indonesia, have developed a filtration prototype using two speakers to create acoustic waves. The force produced by the waves separates the microplastics from the water by creating pressure on a tube of inflowing water. As the tube splits into three channels, the microplastic particles are pressed toward the centre with the clean water flowing toward…

  • Sainsbury’s launches checkout-free store in Central London

    Amazon started experimenting with the concept in 2016 when it opened its first “Amazon Go” branch in Seattle which used what has been dubbed “Just Walk Out” technology. It relies on an accompanying app, which has to be used to enter the store, that tracks whether products are removed from, or returned to, the shelves. Amazon used the same types of technologies found in self-driving cars, such as computer vision, sensor fusion and deep learning to make the concept work. Last year, it announced it would open up its technology platform to other retailers who wanted to trial the technology. Sainsbury’s will now put it to use in a convenience store at Holborn Circus. Customers will need to scan a QR code when entering using their SmartShop app, which is linked to a credit or debit card.…

  • View from India: Research can generate intellectual value

    The computational wave of Covid has spurred the convergence of technology and science at an unprecedented pace. The outcome, which is a portfolio of vaccines and anti-viral drugs, along with online and app-based applications, illustrates the interconnection between basic science and technology. Scale and inclusivity are the hallmarks of the vaccine drive that began in January 2021. “India has administered more than 117 crore [1.17 billion] Covid vaccines under the world’s largest vaccine drive so far,” the Government of India tweeted. This could well be an example of technology facilitating mass manufacturing. The future could be about new drugs to combat infections and decode forms of virus. All this has boosted the intrinsic value of pharma companies. We need to take it to the next level…

  • Autonomous shuttle service kicks off in Oxfordshire

    The new service is being trialled by Darwin Innovation Group, using a shuttle created by Navya. The company previously provided shuttles for trials in an urban setting in Switzerland. The autonomous shuttle service operates at Harwell Science Campus during weekdays, morning to evening. It travels two routes, one along Fermi Avenue and one along Eighth Avenue, with the ESA building being the central stop for both routes. There is no cost to ride the shuttle, which is currently available to campus pass-holders and registered guests of pass-holders. The shuttle – which is battery powered – uses lidar to help navigate safely in its surroundings, in addition to cameras and ultrasound sensors. The shuttle also features a satellite antenna for positioning. While there is no steering wheel, the…

  • Scrapped Scotland-NI bridge ‘would cost £335bn’

    The Prime Minister previously enthused about the possibility of a fixed transport connection between Scotland and Northern Ireland , arguing that it would boost connectivity. The feasibility study, commissioned by Johnson and led by Network Rail chair Sir Peter Hendy, concluded that the project would cost billions of pounds, present serious technical challenges, and take a generation to build. A bridge would cost an estimated £335bn while a tunnel would cost £209bn, the report said. Either structure would be the longest of their kind ever built. The cost “would be impossible to justify”, Sir Peter concluded, stating “the benefits could not possibly outweigh the costs”. The structure would take nearly 30 years to complete planning, design, parliamentary and legal processes, and construction…

  • ‘Super jelly’ material can withstand trampling by elephants

    The material looks and feels like a jelly, with a 'squishy' texture, but when compressed it acts like an ultra-hard, shatterproof glass. Never before has such resistance to compression been incorporated into a soft material. This is even more remarkable considering that it is mostly composed of water. The 'super jelly' could be used for a range of potential applications, including soft robotics, bioelectronics, or even as a cartilage replacement for biomedical use. The behaviour of materials is dependent on their molecular structure. Stretchy, rubber-like hydrogels have many useful properties (such as toughness, flexibility, and self-healing capabilities) that make them a popular research subject, particularly as a potential material for surgical applications. However, making hydrogels…

  • Google commits to privacy oversight from UK watchdog

    The CMA said that Google has laid out a set of commitments from Google regarding its 'Privacy Sandbox' plans, which it said risked squeezing competition by removing third-party cookies and other functionalities from its updated Chrome browser. The new system will split users into cohorts, and rather than a person’s browser history being sent to a central location, their own computer will figure out what they like and assign them to a group with similar interests. Online ads will still be personalised under the system, but Google claims it will afford users greater privacy. Investigators raised concern that Google concealing user data would impede competition in digital advertising markets. The CMA launched its investigation in June this year and heard from more than 40 third parties, who…

  • ‘Magic wand’ imaging technology reveals nano-wonderland

    Materials scientists have developed materials for next-generation electronics so tiny that they are indistinguishable when closely packed. They are so small that, even under the most powerful optical microscopes, they do not reflect enough light (visible light varies in wavelength from 400-700nm) to show fine details such as colours. For instance, carbon nanotubes merely appear grey under an optical microscope. The inability to distinguish fine details and differences between individual pieces of nanomaterials makes it difficult for scientists to study their unique properties and discover ways to perfect them for practical applications. The advance permitted by this new technique improves colour-imaging resolution to an unprecedented 6nm level, helping scientists view nanomaterials in enough…

  • Over 300 new exoplanets identified from Kepler data

    The term ‘exoplanets’ is used to describe planets outside of our own solar system. The number of exoplanets that have been identified by astronomers totals fewer than 5,000 in all, so the identification of hundreds of new ones is a significant advance. The team from University Of California – Los Angeles (UCLA) believe that studying such a large new group of bodies could improve understanding of how planets form and orbits evolve, and it could provide new insights about how unusual our solar system is. “Discovering hundreds of new exoplanets is a significant accomplishment by itself, but what sets this work apart is how it will illuminate features of the exoplanet population as a whole,” said Erik Petigura, a UCLA astronomy professor and co-author of the research. One challenge in identifying…

  • Synthetic diamond glass is hardest known material of its kind

    The new ultrahard glass has a wealth of potential applications for electronic devices. When it comes to comprehending the properties of materials, function follows form. How a material’s atoms are chemically bonded, and their resulting structure, determines its physical qualities. This applies both to properties observable to the naked eye and those more subtle qualities only revealed by probing with specialist instrumentation. Carbon has unrivalled versatility when it comes to forming stable structures, both alone and in combination with other elements. Some carbon-based materials have highly organised structures (e.g. diamond structure) with repeating crystalline lattices while others are more disordered or amorphous. Glass is a non-crystalline, amorphous material typically formed by…

  • 3D-printed prosthetic eye fitted at Moorfields Eye Hospital

    Conventionally, patients requiring an eye prosthesis receive a painted acrylic eye. During a two-hour session, the eye socket is moulded to create a comfortable prosthetic; this invasive procedure can be so difficult that it can require a general anaesthetic when the patient is a child. The eye is then painted. This process takes six weeks. The 3D-printed eye is more realistic, having clearer definition and “real depth” to the pupil. For conventional acrylic eyes, the iris is hand-painted onto a black disc embedded in the prosthesis, meaning that light cannot pass the full depth of the eye, while light can interact more naturally with the 3D-printed prosthesis. However, a 3D-printed prosthetic is not only more realistic but also reduces the manufacturing process to two to three weeks. The…

  • China sees first fall in carbon emissions since pandemic recovery

    The country, which is the world’s largest carbon emitter, saw it emissions rise by approximately 9 per cent in the first half of the year before tapering off in the following months. The analysis from the Helsinki-based Centre for Research on Energy and Clean Air (CREA) found that much of the savings were achieved through emission declines in fossil fuel and concrete usage. Furthermore, the declining trend in the third quarter steepened into September – the first month during which monthly emissions returned to 2019 levels – and looks set to deepen further in October, based on preliminary data. This analysis is based on official figures for the domestic production, import and export of fossil fuels and cement, as well as commercial data on changes in stocks of stored fuel. In the case…

  • Smart sleeve lets wearer feel and understand any foreign language

    Through these vibrations, it is possible to understand any foreign language. The HART team plans to present its application tomorrow (Friday) to a number of fellow students on the campus of TU/e. It is thought that this is the first time that a sleeve with vibrating motors has been used for communication. The students have developed a 'vibratory language' based on the 39 different sounds of the English language. The sleeve works with a computer programme that converts written text into English and then into sound units, which in turn are converted into vibrations. Each sound has its own vibration. The vibrations that a user feels on his or her arm through the sleeve, together form words and sentences. Team member Lisa Overdevest, an Industrial Engineering student (pictured below), learned…

  • AI algorithm more accurately predicts when patients have developed sepsis

    Sepsis affects more than 30 million people worldwide, causing an estimated six million deaths. It is an extreme response from the human body to an infection and is often life-threatening. Every hour of delayed treatment can increase the odds of death by 4-8 per cent, so timely and accurate predictions of sepsis are crucial to reduce morbidity and mortality. Various healthcare organisations are already deploying predictive analytics to help identify patients with sepsis by using electronic medical record (EMR) data. But the new AI, developed by a team of international researchers from McMaster University and St Joseph’s Healthcare Hamilton, both in Canada, could greatly improve the timeliness and accuracy of data-driven sepsis predictions. “Sepsis can be predicted very accurately and very…

  • Tough cyber-security rules for internet-connected devices laid before parliament

    The Product Security and Telecommunications Infrastructure Bill (PSTI) introduces a raft of new protocols that manufacturers and distributors of tech will need to adhere to. It will allow regulators to ban universal default passwords, force firms to be transparent to customers about what they are doing to fix security flaws in connectable products, and create a better public reporting system for vulnerabilities found in those products. The Bill will also speed up the roll-out of faster and more reliable broadband and mobile networks by making it easier for operators to upgrade and share infrastructure. The reforms will encourage quicker and more collaborative negotiations with landowners hosting the equipment, to reduce instances of lengthy court action which are holding up improvements…

  • ‘Living walls’ reduce heat loss by over 30 per cent

    The study was centred around the university’s own Sustainability Hub, an unremarkable pre-1970s building on the university campus. It was conducted by academics associated with Plymouth’s Sustainable Earth Institute. The researchers compared how effectively two sections of its walls retained heat. Despite being on the same west-facing elevation, one of the walls had been retrofitted with an exterior 'living wall' façade comprised of a flexible felt system with pockets for soil and planting. The other part of the wall was left plain. Following five weeks of measurements, the Plymouth researchers found that the amount of heat lost through the wall retrofitted with the living system was 31.4 per cent lower than that of the unchanged wall. They also discovered that daytime temperatures within…

  • UK finally embraces tidal stream projects with £20m annual subsidy

    Tidal energy is created using the movement of tides and oceans, where the intensity of the water from the rise and fall of tides is a form of kinetic energy that is converted into electricity. It can be harnessed in three different ways - tidal streams, barrages and lagoons - but has been relatively uneconomical compared to other forms of renewable electricity such as wind and solar. However, unlike those forms of generation, which produce variable electricity output depending on the climactic conditions, tidal energy offers a predictable and constant flow that makes it easier for engineers to design efficient systems. The government said that it hopes the latest investment will boost the popularity of the technology. As part of the fourth allocation round of the 'Contracts for Difference…
