• Ethereum drastically reduces its energy use with ‘Merge’ software upgrade

    The Ethereum 'Merge' software upgrade has gone live, paving the way for more energy-efficient blockchain networks.  The upgrade, which changes how transactions occur and how ether tokens are created, could give Ethereum - crypto’s most important commercial highway - a major advantage as it seeks to surpass rival blockchain Bitcoin. Under the change, Ethereum will move from a 'proof of work' system, in which energy-hungry computers validate transactions by solving complex maths problems, to a 'proof of stake' system, where individuals and companies act as validators using the network’s native token Ether as collateral to win newly created tokens. The completion of the upgrade was announced by Ethereum inventor and co-founder Vitalik Buterin on Twitter on Thursday. And we finalized…

  • How fleet operators are making the switch to EVs

    Switching large commercial fleets from internal-combustion engines (ICEs) to electric vehicles (EVs) could cut the total cost of ownership by between 15 and 25 per cent, according to an estimate by McKinsey and Company. Big owners are already getting on board, also with an eye on net-zero targets. Amazon and Hertz have placed orders for 100,000 EVs in the US to replace ICEs in, respectively, their delivery and rental fleets. Amazon is also investing in renewable energy to partly power its fleet and wider activities as it transitions. These players are adopting EVs at pace. Courier DHL aims to have more than 80,000 in its global fleet by 2030. In the UK, it had grown its fleet of electric Transit vans to 270 by March, having added the first 50 in 2021. They now service more than 30 towns…

  • Wearable health sensors woven into t-shirts and face masks

    Potential applications for this range from monitoring exercise, sleep quality and stress, to diagnosing and monitoring disease through breath and vital signs. The sensors cost very little to manufacture, spun from a new Imperial-developed cotton-based conductive thread called Pecotex. For around 10p, one metre of thread can be produced to seamlessly integrate more than ten sensors into clothing. Pecotex is also compatible with industry-standard computerised embroidery machines. Fahad Alshabouna, first author of the research and a PhD candidate at Imperial’s Department of Bioengineering, said: “The flexible medium of clothing means our sensors have a wide range of applications. They’re also relatively easy to produce which means we could scale up manufacturing and usher in a new generation…

  • Unlocking AI’s full potential for beating cancer

    For decades, experts have been exploring how artificial intelligence can help detect breast cancer. Yet cases continue to rise. Deaths continue to devastate, and all of AI’s promise is yet to materialise. We look at what is hindering progress in this space, and what needs to be done for AI’s true, life-saving potential to be realised. Four women are diagnosed with breast cancer every minute across the globe, a third of whom die from the disease. As of 2020 – the last year for which we have full and verified figures – breast cancer is the most prevalent form of the disease, affecting one in eight women during their lifetime. This ongoing prevalence has seen breast cancer become one of the most well researched, well funded and well understood cancers of our time. It’s also why, of all the…

  • Elon Musk's Tesla sued over ‘misleading’ Autopilot advertising

    The lawsuit filed in San Francisco by a Tesla owner claims the automaker has been “deceptively and misleadingly” marketing the Autopilot and “Full Self-Driving” advanced driver assistance features since 2016.  Briggs Matsko, the named plaintiff, said Tesla did this to "generate excitement" about its vehicles, attract investments, boost sales, avoid bankruptcy, drive up its stock price and become a "dominant player" in electric vehicles, despite knowing that the technology was not yet there.  "Tesla has yet to produce anything even remotely approaching a fully self-driving car," Matsko said. Matsko reportedly spent $5,000 for the Enhanced Autopilot package in 2018, which was sold as a precursor to “Full Self-Driving” tech, a  $15,000 software add-on package that is still not ready to ship…

  • After All: Islanders show that remoteness breeds resourcefulness

    Modern technology is always one step ahead of me. Before sitting down to write this second column about my recent journey to the Scottish Islands on board MV Greg Mortimer, I thought it would be good to know which seas the hardworking small ship was surfing at that particular moment. I was about to phone Aurora Cruises, the vessel’s owner, when an IT-savvy friend referred me to the website www.vesselfinder.com . From there I gleaned that: “The current position of Greg Mortimer is at North East Atlantic Ocean (coordinates 65.5679 N / 24.6406 W) reported 11 days ago by AIS. The vessel is en route to the port of Sisimiut, Greenland, sailing at a speed of 10.6 knots... Current draught: 5.2m...” I could almost feel a cool Arctic whiff of the “5.2m draught” on my face, the draught that would…

  • Teardown: Apple MacBook Air 2022

    Apple released the first general-user MacBook Air laptop based on its M2 processor in July with UK retail prices starting at £1,249. The company says it represents the first major redesign of the computer in essentially a decade, with its move to producing its own silicon driving many of the changes. Weighing just 1.24kg and at only 1.13cm thick, the 13.6-inch-​screen laptop fits comfortably into a traditional A4/Letter envelope (though obviously that’s not a recommended portability option). At the same time, the M2 – here in an 8-core CPU/8 or 10-core GPU configuration – offers 1.4x better performance on a video editing benchmark than the M1-based edition. Apple is also claiming a 15x improvement for video against earlier MacBooks that used Intel’s Core i5 chips (although, for context…

  • Plug-in sales soar, but where will they plug in?

    The sale of electric vehicles (EVs) has skyrocketed in the UK in recent years, but analysis by E&T reveals that the deployment of chargepoints across the nation is not keeping pace with the record growth in EVs on the road. According to the latest quarterly figures from the Department of Transport, there was a 62 per cent rise in newly registered plug-in vehicles in January-March 2022 over Q1 2021. In comparison, the number of newly registered petrol vehicles fell by 7 per cent and diesel registrations fell by 34 per cent. The sale of new plug-in vehicles has soared over the last five years by 665 per cent. Meanwhile the number of newly registered petrol vehicles has fallen by 50 per cent and diesel by 76 per cent. ...

  • Portable device might help stroke survivors hold hands with loved ones

    Stroke survivors who have lost their sense of touch may be able to feel the warmth of a loved one’s hand again thanks to a portable device being developed by UK researchers. One of the most common side-effects of a stroke is the loss of sensation and muscle control in one arm and hand, which makes it difficult for survivors to dress and feed themselves, or even handle everyday objects such as a toothbrush or door handle. In order to support them, a team of researchers at the University of Hertfordshire have created a touchpad device that delivers tiny vibrations to the fingertips, causing brain cells to fire and bring back a sense of touch to affected limbs. The device could not only make survivors more independent but also help them reconnect with loved ones.  “Improvement in touch…

  • Analysis: Is the electricity network ready for an EV revolution?

    A revolution is coming – and it will be powered by electricity. As part of the government’s net-zero drive, and with a looming 2030 ban on the sale of new petrol and diesel cars, up to 30 million electric vehicle chargers will need to be installed by 2050, according to the trade association for energy infrastructure companies, BEAMA. On top of that, the association says 20 million heat pumps will also be required, increasing electricity demand by more than 70 per cent. Merlin Hyman, chief executive of Regen, a think tank with the mission of helping the UK achieve a net-zero energy system, describes this as “a massive ask”. He notes that the EV revolution involves transferring an entire energy supply chain – one that (until now) has been delivered via oil tankers through the Strait of Hormuz…

  • The clean energy transition could save trillions, say Oxford researchers

    Switching from fossil fuels to renewable energy is "possible and profitable", and could save the world as much as $12tn (£10.2tn) by 2050 compared to continuing the current levels of fossil fuel use, according to a study by Oxford University.  In the paper, the research team denied the idea that a green transition would be extremely costly as "just wrong", and described a scenario in which rapidly transitioning to clean energy results in lower energy system costs than a fossil fuel system, while providing 55 per cent more energy to the global economy, and expanding energy access to more people around the world.   The study’s ‘Fast Transition’ scenario could be achieved by ramping up solar, wind, batteries, electric vehicles, and clean fuels such as green hydrogen, the scientists said. …

  • Twitter shareholders approve Musk's $44bn takeover bid

    Twitter is moving forward to attempt to force Elon Musk to uphold his agreement to buy the social media company, as its shareholders vote to approve the buyout.  The billionaire   made an offer   last April   to purchase Twitter f or $ 44bn (£35bn). However, he later   backed down   from the deal, stating that the acquisition could not go forward until the company provided information about how many accounts on the platform are spam or bots. The vote, made in a short conference call with investors from the company's San Francisco headquarters, could have spelt the end of Twitter's legal pursuit. However, the shareholders' decision has given the company the green light to try to force Musk to buy the company in the courts, a process that began on 12 July, when Twitter sued Musk in Delaware…

  • How trusted digital twins can unlock the UK’s sustainability efforts

    Sustainability has been on the public agenda for years with comparatively little progress being made given the risks. The COP26 conference that took place towards the end of last year, and the introduction of sustainability goals by the UK government to be met by 2030, though, have pushed the topic to the top of the corporate and government agenda. Despite increased effort and interest in sustainability, with solutions such as alternative energy and the restoration of peatlands in agriculture having seen increased investment, experts are still warning that the UK’s current plans may fall short of reaching key climate goals. While there is no silver bullet to the sustainability issues we’re currently facing, technology - particularly digital twin - has already played a vital role in helping…

  • £3.5bn fine for Google from EU over Android's anti-competition activities

    The European Court of Justice’s General Court mostly confirmed a European Commission decision to slap Google with a fine of more than four billion euros for stifling competition through the dominance of Android. The court said it was appropriate to impose a fine of €4.125bn (£3.5 billion) on Google, slightly lower than the original €4.34bn penalty. In addition, the court said its reasoning for the decision differed “in certain respects” from the Commission’s. The fine is one of three anti-competition penalties totalling more than €8bn (£6.9bn) that the European Commission imposed on Google between 2017 and 2019. In its original decision, the Commission said Google’s practices restrict competition and reduce choices for consumers. It determined that Google broke EU rules by requiring…

  • Can the road network cope with self-driving vehicles?

    As the Boris Johnson administration drew to a close, one government department that didn’t get the memo to down tools was the Department for Transport. In August, the DfT announced a £100m funding boost for what it called a “self-driving revolution”, setting Britain on a course towards a future where autonomous cars, coaches and lorries could be running on our roads from as early as 2025. It’s simultaneously a bold new step and utterly uncontroversial, as whoever is living in Downing Street is going to have to deal with the reality that autonomous vehicles (AVs) are coming. However, what’s important about AVs is not just what Tesla, Google, and maybe even Apple are up to. What’s going to be just as critical is the road network on which the ‘revolution’ takes place. So just how are AVs going…

  • The bigger picture: Kinetic glasshouse

    Designed by Heatherwick Studios in collaboration with the Woolbeding Charity and the National Trust, the conical structure at the Trust’s Woolbeding Gardens in West Sussex can unfold like the flowers inside it, letting in sunlight and fresh air. Ten steel ‘sepals’ with glass and aluminium façades take four minutes to open using a hydraulic mechanism, creating an immense 141-square-metre space in the shape of a crown. Image credit: Cover Images As well as protecting the plants inside it, the kinetic glasshouse offers a decorative element to the Silk Route Garden around it, representing a landscape influenced by the ancient trading route between Asia and Europe. A winding path takes visitors through 300 species and 12 distinct regions, from Mediterranean evergreens…

  • Blockchain could help drive ethical EVs

    Electric vehicles (EVs) are hailed as the greenest cars available, and by 2030 they will account for around 32 per cent of the total market share for new car sales, according to one report. Deloitte forecasts their numbers will grow from 2.5 million in 2020 to 11.2 million in 2025 to 31.1 million by 2030. However, due to their reliance on batteries, the increasing popularity of EVs means more minerals are needed to create them. Without knowing the provenance of goods or minerals, it is difficult for carmakers to ensure that materials used in the manufacturing process comply with social and environmental standards, which are increasingly important to a growing number of eco-conscious consumers. To provide transparency across its supply chains, a British start-up called Circulor is using…

  • Book review: ‘She’s In CTRL’ by Anne-Marie Imafidon

    It is clear that technology is no natural force advancing in whichever direction it pleases, but that it is driven by the very people who create it: overwhelmingly men in the Global North. It is unsurprising, then, that technology tends to reflect their experiences and serve their interests. The efforts of women from within and beyond the sector have drawn attention to this problem: Timnit Gebru, Joy Buolamwini, Caroline Criado Perez, Ellen Pao. Dr Anne-Marie Imafidon certainly ranks among them. A computer scientist and former child prodigy, she founded Stemettes in 2013: a social enterprise supporting under-represented groups in STEM, especially young women. In ‘She’s in CTRL’ (Bantam Press, £16.99, ISBN: 9781787635029), Imafidon makes the case that the tech world should not be considered…

  • Scientists design a novel way to extract silver from solar panels

    The process discovered is able to recover metals from end-of-life solar panels using cheap, environmentally friendly solvents (substances used to dissolve, extract, or suspend other substances). Silver is an essential metal for  the functioning of solar panels. However, the amount of naturally occurring silver found in ores is decreasing, making supply a concern for the future. This not only affects the production of photovoltaic (PV) cells – aka solar cells – but other essentials such as LED chips, nuclear reactors and equipment for the medical industry. For this reason, the University of Leicester team set out to find a way to recover the silver used in discarded panels.  “These new ‘unusual’ brines offer new possibilities for the processing of metals," said Dr Guillaume Zante, from…

  • Could EVs overload the power grid?

    An £11.4m programme of funding by the Department for Business, Energy and Industrial Strategy is getting off the ground to make it easier for an electric vehicle (EV) to return electricity to the network during times of peak loading. Since June, all new private chargepoints must be smart enough to adjust their rate of charge in response to external signals, in order to ease demand on the network at times like the evening peak. There are clear reasons as to why the British government, among others, is keen to have EVs react to the needs of the grid. Without that ability, the risk is that if too many drivers in the same area demand their cars be ready to drive in the next hour it will lead to sudden blackouts. There are distinct differences of opinion on how disruptive EV charging will be…

  • UN begins nuclear safety consultations with Russia and Ukraine

    Rafael Grossi, the director-general of the International Atomic Energy Agency (IAEA), said on Monday that he has started consultations with both Ukraine and Russia to protect the area around Europe's largest nuclear power plant, despite the conflict between the two nations.  The head of the UN nuclear watchdog agency  made his proposal last week after leading a team of inspectors to the nuclear plant - Europe’s biggest, having six reactors - but gave few details at the time. “What we need here really is Ukraine and Russia to agree on a very simple principle of not attacking, or not shelling, at the plant,” Grossi told reporters at the agency’s Vienna headquarters. Last week, the plant was   knocked off Ukraine’s electricity grid after a fire caused by Russian shelling brought down its…

  • Ocean cooling debunked as hurricane prevention idea

    The study led by scientists at the University of Miami (UM) Rosenstiel School of Marine, Atmospheric and Earth Science showed that the amount of energy that would be needed to weaken a hurricane before landfall would make ocean cooling an inefficient solution to mitigate natural disasters. “The main result from our study is that massive amounts of artificially cooled water would be needed for only a modest weakening in hurricane intensity before landfall,” said the study’s lead author James Hlywiak, a graduate of the UM Rosenstiel School. “Plus, weakening the intensity by marginal amounts doesn’t necessarily mean that the likelihood for inland damages and safety risks would decrease as well." Hurricanes feed off warm waters and they weaken once they hit land or cooler parts of the ocean…

  • Blue Origin’s New Shephard rocket suffers first launch failure

    Blue Origin's New Shepard rocket was less than a minute into the flight when bright yellow flames shot out from around the single engine at the bottom. Immediately, the capsule’s emergency launch abort system kicked in, lifting the craft off the top. Several minutes later, the capsule parachuted onto the remote desert floor and crashed back into West Texas with no injuries or damage reported, according to the Federal Aviation Administration (FAA).  The rocket did not carry any human passengers, only science experiments. However, this same model of rocket is also used to launch people on 10-minute rides to the edge of space. "It appears that we've experienced an anomaly with today's flight," said Dr Erika Wagner, a senior director at Blue Origin, while doing the in-flight webcast commentary…

  • Book interview: ‘Playing to Win’ and the rules of gamification

    “I don’t think that anyone is going to be surprised by the fact that companies are trying to maximise profit,” says Adrian Hon. Neither does he think that people will be shocked to hear that authoritarian governments are “interested in controlling and manipulating citizens”. None of this is new, says the author of ‘You’ve Been Played’, “and it certainly existed long before the arrival of gamification”. What’s interesting, he says, is that gamification – the application of game-design elements and principles in non-game contexts – is becoming a new tool to achieve these pre-existing aims. The difference is that the incentives for modifying user behaviour are “styled deliberately to look like video games, with missions and quests, using interface symbols and elements that people are familiar…
