• Postcode history goes on show

    Visitors can try their hands at coding post, and an original 1950s ELSIE electronic sorting unit derived from wartime code-breaking technology will be on display, along with previously unseen 19th-century maps of London. Public use of postcodes for machine sorting was first trialled in Norwich in 1959. When the scheme was rolled out nationwide, the three-letter NOR code was replaced by two letters and a number.

  • New tool could lead to more efficient ways to capture carbon

    Such carbon-capture technology, developed by researchers at the University of Colorado Boulder, may help limit global warming this century to 1.5°C above pre-industrial temperatures and fend off the catastrophic effects of global climate change. The method predicts how strong the bond will be between carbon dioxide and the molecule that traps it, known as a binder. Experts can easily apply this electrochemical diagnosis to any molecule that is chemically inclined to bind with carbon dioxide, allowing researchers to identify suitable molecular candidates with which to capture carbon dioxide from the air. “The Holy Grail, if you will, is to inch toward being able to use binders that can grab carbon dioxide from the air [around us], not just concentrated sources,” said Oana Luca, assistant…

  • Teardown: Right to repair

    The right-to-repair movement finally began to get some traction last year. The UK introduced its law last summer, although it does not yet include consumer electronics such as smartphones, tablets and computers. France, however, did include handsets in its legislation, which came into law at the beginning of 2021. These need to carry a repairability score in stores and online, and manufacturers must commit to supplying replacement parts in a timely way. Elsewhere, right-to-repair regulation is advancing at both state and federal level in the US and Germany. In spring last year, the EU introduced regulations that require manufacturers to support repairs for a minimum of 10 years, although the thorny issue of who carries them out has been effectively devolved to how member states interpret…

  • How to grow concrete and other building materials

    Concrete is the most widely used man-made material, and second only to water as the most-consumed resource on Earth. Incredibly, 7.3 billion cubic metres of concrete is poured every year, accounting for 8 per cent of carbon dioxide emissions. While greener concrete may help curb some of the environmental damage done by our favourite building material, we will probably need even more of it. After all, our growing global population, which is expected to top 9.7 billion by 2050, will need new homes and we will need efficient ways to maintain current houses and infrastructure too. Self-healing concrete is one part of the solution to this global challenge. Engineers have developed forms of it that contain capsules which release a healing agent to fix cracks when they are split open. Using this…

  • Tiny sensors designed to float in the wind like dandelion seeds

    Wireless sensors can monitor how temperature, humidity or other environmental conditions vary across large swaths of land, such as farms or forests. These tools could be used for a variety of applications, including digital agriculture and monitoring climate change. One problem, however, is that it is currently time-consuming and expensive to physically place hundreds of sensors across a large area. The Washington team developed a sensor-carrying device that can be blown by the wind as it tumbles toward the ground. This system is about 30 times as heavy as a 1mg dandelion seed but can still travel up to 100 metres in a moderate breeze from where it is released by a drone. Once on the ground, the device, which can hold at least four sensors, uses solar panels to power its onboard electronics…

  • Stackable ‘Holobricks’ used to create giant 3D displays

    The holobrick proof-of-concept can tile holograms together to form a large seamless 3D image. A 2D full HD display needs an information data rate of about three gigabits per second, but a 3D display of the same resolution would require a rate of three terabits per second, which is not yet available. “Delivering an adequate 3D experience using the current technology is a huge challenge,” said Professor Daping Chu from Cambridge’s Department of Engineering, who led the research. “Over the past ten years, we’ve been working with our industrial partners to develop holographic displays which allow the simultaneous realisation of large size and large field-of-view, which needs to be matched with a hologram with a large optical information content.” Reconstructed holographic…

  • DNA-based bio-batteries make powerful progress in lab tests

    Defence Science and Technology Laboratory (Dstl) scientists are working on the bio batteries in a collaborative project with Touchlight Genetics, the Office of Naval Research Global (ONRG) from the US Department of Defense, and the University of Utah. Dstl’s synthetic biology lead Petra Oyston explained: “The current battery technology that our soldiers are using is containing a lot of energy in chemical format, and if that battery gets shot for example it’s going to explode and burst into flames. “Our bio-battery is made out of DNA, enzymes, lactate and water. If you shot it it would just go splat, so there’s a significant safety benefit.” The concept behind the batteries is to degrade a naturally occurring product such as lactate, using enzymes bound to a DNA structural scaffold. The…

  • Shenzhen shut down as China’s Covid cases double

    China's National Health Commission said 3,507 new locally spread cases had been identified in the latest 24-hour period, up from 1,337 a day earlier. A fast-spreading variant known as 'Stealth Omicron' – the B.A.2 lineage of the Omicron variant – is testing China’s zero-tolerance strategy, which has previously kept the virus at bay after a deadly initial outbreak in early 2020. Most of the new cases were in north-east China’s Jilin province, where 2,601 were reported. Smaller outbreaks have occurred around the country, including in the major cities of Beijing, Shanghai and Shenzhen. At the weekend, China’s government responded to a spike in coronavirus infections by shutting down the southern business centre and manufacturing hub of Shenzhen, a city of 17.5 million people, and restricted…

  • Moon Gallery aboard ISS welcomes artworks from Singapore

    Researchers successfully launched the two artefacts into space recently as part of a test flight by the Moon Gallery and will come back to Earth after 10 months. Currently comprising 64 artworks made by artists all around the world, the Moon Gallery will eventually comprise 100 artworks. Astronauts also plan to place this collection on the Moon by 2025. The new artworks are two metal cubes featuring unique artworks, each measuring 0.98cm all around, designed by Singaporean artist and architect Lakshmi Mohanbabu, who sought to create new artworks using technology and to revolve around concepts of unity, diversity and complexity in humankind. Both cubes were borne out of a partnership between Lakshmi and scientists from the Nanyang Technological University, Singapore (NTU Singapore), supported…

  • Method for recycling wind turbine blades almost ‘waste-free’

    According to the researchers from Kaunas University of Technology (KTU), Lithuania, the extracted materials can then be reused and the process is virtually waste-free. Wind turbine blades made from glass fibre-reinforced polymer (GFRP) laminate composites can serve for up to 25 years, but after that they typically end up in landfills. The material is recognised as hard-to-break-down and has become a real challenge for the renewable energy industry. It is estimated that wind turbine blades account for 10 per cent of Europe’s fibre-reinforced composite material waste. Concerns have been raised that with the increase in renewable facilities, wind turbine blade waste will increase to around two million tonnes globally by 2050. With many countries banning composite materials from their landfills…

  • Merger between Norton and Avast paused over competition concerns

    The US-based NortonLifeLock had been planning to purchase UK firm Avast for £6bn but the CMA is now considering an “in-depth investigation” into the merger before the transaction is allowed to continue. Both firms offer cyber safety software to consumers under a variety of different brands. Products include antivirus software (also known as endpoint security software), privacy software (such as VPNs) and identity protection software. As the companies are close competitors, with few other significant rivals, the CMA said it was concerned that if completed, the proposed deal could lead to a reduction in competition in the UK market. This could lead to UK consumers getting a worse deal when looking for cyber safety software in the future, it added. David Stewart, CMA executive director…

  • Tens of thousands of home EV chargers could be dangerous

    The report, which was not made public but has been seen by E&T, was compiled last summer by the Centre of Excellence for Low Carbon and Fuel Cell Technologies (Cenex) for the Office for Zero Emission Vehicles (OZEV). It shows that of the 371 audits carried out on electric vehicle chargepoints (EVCP) installed as part of the Electric Vehicle Homecharge Scheme (EVHS), 66 were found to have dangerous or potentially dangerous issues in one or more categories. This represents 17.8 per cent of the installations audited. Of all the new chargepoint installations carried out, only 32 per cent were recorded as satisfactory. The findings prompted transport minister Rachel Maclean to write to all installers registered on the scheme to warn them that if necessary “we will remove companies and individuals…

  • The smart solutions to ageing UK healthcare infrastructure

    In October 2020, the UK's National Health Service released its ambitious strategy [PDF] to become the world’s first 'net zero' national health service. Even amid the myriad pressures of coronavirus, NHS chief executive Simon Stevens made clear that the climate emergency is one of the most significant health issues to be tackled. In his words: “With poor environmental health contributing to major diseases, including cardiac problems, asthma and cancer, our efforts must be accelerated.” As the largest employer in Britain, responsible for around 4 per cent of the nation's carbon emissions, it is clear that the will for a net-zero NHS is there. At the same time, with an ageing population and constant concerns over the costs of delivering high-quality care, the NHS is facing a perfect storm of…

  • When building preservation gets ugly (or beautiful)

    Brutalist buildings aren’t meant to be brutal. In fact, their name arguably comes from modernist architects’ love of béton brut or raw concrete, which to Le Corbusier and co was the epitome of modern elegance. Brutalist buildings are perhaps best characterised by their minimalist, angular constructions that showcase their structural elements and building materials, such as concrete, brick, steel, timber, and glass, but the definition is even disputed by architects. What is certain is that these bold buildings were intended to fulfil a need for affordable housing following the Second World War and help regenerate bombed cities. However, some people came to associate Brutalist buildings with totalitarianism. The architectural style dominates in parts of the USSR and, unlike the Berlin Wall…

  • Intel picks Germany for Silicon Junction

    Intel has picked Magdeburg, a city in the north of Germany, as the destination for a mega fab that will employ 3000 specialists with an initial investment of €17bn. The site will represent what Intel CEO Pat Gelsinger called the Silicon Junction for its ambitions on the continent. In announcing the decision, which is the result of a project to find a suitable European site for around a year and which comes a matter of weeks after the European Union unveiled its €43bn Chips Act, Gelsinger said a new fab needed to be built around an existing ecosystem. The German fab will not be far from an existing chipmaking hub Dresden as well as the leading supplier of lithography equipment ASML in The Netherlands.   In a video made for the announcement, Gelsinger said details of the financial support…

  • Airlines and airports scrap Covid restrictions as infections rise

    The UK is one of the first major economies to remove all its remaining travel restrictions even though Covid infections are on the rise once again. The last week has seen a 25 per cent increase in cases to over 170,000, with hospitalisations also rising over 10 per cent. From this Friday, all travel restrictions will be lifted, including the passenger locator form for arrivals into UK, as well as all tests for passengers who do not qualify as vaccinated. The change removes the need for unvaccinated passengers to take a pre-departure test and a 'day two' post-arrival test. The government said the changes are being implemented due to the success of the vaccine rollout, with 86 per cent of the population now having received a second dose and 67 per cent with a booster or third dose. Face…

  • UK to make ‘big bets’ on nuclear power in move away from Russian oil

    Last week, the government committed to phase out Russian oil by the end of the year in response to Russia's aggressive actions in Ukraine. Writing in the Telegraph , Johnson said that his government wanted to “exploit the potential” of renewable energy technologies including tidal power, hydro and geothermal energy but that consistent baseload electricity generation could be met with nuclear when renewables aren’t generating. The strategy would include small modular reactors as well as more traditional, larger power stations. “It was the UK that first split the atom. It was the UK that had the world’s first civilian nuclear power plant. It is time we recovered our lead,” Johnson wrote. Just last month, the UK Office for Nuclear Regulation approved the design for a new nuclear power…

  • Hoverfly brains inspire method for detecting distant drones

    Autonomous systems experts from the University of South Australia (UniSA), Flinders University and defence company Midspar Systems say that trials using bio-inspired signal-processing techniques show up to a 50 per cent better detection rate than existing methods. The findings could help combat the growing global threat posed by IED-carrying drones, including in Ukraine. Anthony Finn, UniSA professor of autonomous systems, said that insect vision systems have been mapped for some time now to improve camera-based detections, but this is the first time that bio-vision has been applied to acoustic data. “Bio-vision processing has been shown to greatly increase the detection range of drones in both visual and infrared data. However, we have now shown we can pick up clear and crisp acoustic…

  • Testing facility for lower carbon rocket engines opens in Scotland

    The state-of-the-art facility, which is the largest of its kind in the UK, represents another step forward for the UK’s burgeoning space sector. The government currently hopes to grow the UK’s share of the global space market to 10 per cent by 2030. It aims to build multiple spaceports in the UK, with a view to seeing commercial sub-orbital spaceflight and space tourism from UK spaceports. In October, Skyrora signed a deal with a spaceport based on the Shetland islands that could see rocket launches take place in the UK this year at the earliest. It said its new Midlothian facility would have a lower carbon footprint compared to having to transport engines and equipment to third-party facilities. It will also harness its natural surroundings and use rainfall from the Scottish Lowlands…

  • The Pantheon: still the world’s largest reinforced concrete dome

    If there Was a competition to find the most durable and beautiful concrete structure ever built, the Pantheon in Rome would most surely win the prize. It also stands as a monument to the genius of Roman concrete. Commissioned by Hadrian (who was emperor 117-138 CE) as a temple to all the gods, the Pantheon replaced Agrippa’s earlier temple following a fire. It is still the most visited site in Italy, having weathered centuries of tourists, floods, wars and earthquakes. Its huge concrete dome – 43.4m in diameter and 21.75m high – was unrivalled in size until the building of Florence Cathedral in the 1400s, and is still the largest ever made with unsupported concrete. “The mastery of building something so daring and having the structure resist essentially without any structural support…

  • Insulation simple solution to slash energy bills, as government considers more coal

    An Energy and Climate Intelligence Unit (ECIU) assessment has found that six million homes had been upgraded to energy performance certificate band C from 2009 to 2019 courtesy of relatively simple home-improvement measures such as loft and cavity wall insulation. Upgrading a home from band D to band C cuts gas demand by 20 per cent per home, saving each one around £194 per year from April 2022 – and potentially even more if energy bills climb further, as is expected in the face of ballooning gas prices due to reduced supply, increased demand and Russia's invasion of Ukraine. The energy efficiency measures installed in the decade to 2019 will save bill-payers an estimated £1.15bn this year, the organisation said. As debate rages on how to tackle surging energy bills, green campaigners…

  • Ukraine to receive 500 generators from UK in efforts to keep electricity flowing

    The donation follows direct requests from President Zelenskyy in recent discussions with the UK's Prime Minister Boris Johnson and business secretary Kwasi Kwarteng. The UK government has created a dedicated taskforce, including distribution network operators and the Energy Networks Association, to source and send the generators to Ukraine, which could provide enough to power around 20,000 homes or equivalent buildings. Some of Ukraine’s key facilities including hospitals, shelters and water treatment plants have lost power during the ongoing Russian invasion. Russian forces have attacked some key infrastructure during the invasion, including a high-voltage power line that links to the Chernobyl nuclear plant. Ukraine recently told the UN nuclear watchdog that staff operating radioactive…

  • Stricter rules for online purchases come into force today

    A new set of Strong Customer Authentication (SCA) requirements are being implemented that will change how people confirm their identity when making online purchases. The British Retail Consortium (BRC) said that customers will now be asked to prove their identity when making a purchase, by confirming their identify through two of the following three ‘factors’: Something they are – like a fingerprint or facial ID Something they know – like a passcode or password Something they have – like a mobile phone The SCA rules have already been applied to a small number of transactions for some time, but the proportion of transactions which need to adhere to the new requirements has been steadily increasing since the start of this year as merchants prepared themselves to meet the enforcement…
