• Bizarre Tech: Y-Brush, BeautyMix and Livall smart helmet

    See my video from IFA 2022 here Y-Brush Get in my mouth! I saw this on a stand at the Showstoppers event at IFA, and thought it was some sort of smart denture cleaner. But alas, I was mistaken. Now, I love me some dental hygiene: I have a sonic toothbrush, a water flosser, and mouthwash. But good lord, it can be tedious. According to the makers of the Y-Brush, 90 per cent of case studies show that teeth brushing is not done correctly, and that your gnashers should be brushed for two to three minutes twice a day – that’s four seconds a tooth. With the Y-Brush, it reduces time spent brushing – you literally don’t need to do it. Just bite down on it and it gets to work obliterating the plaque and nasties in your mouth. I didn’t test it when they handed it to me. Obviously, it wasn’t…

  • Book review: ‘Positive People Leadership’ by Nigel Rowe

    Not many of us will have sufficient spirit of inquiry to work out how many bosses we’ve reported to in our careers. But Nigel Rowe has, and as his debut book ‘Positive People Leadership’ (The Book Guild, £9.99, ISBN 9781914471704) posits, there’s a lot to be learned from such data. During his three-decade (and counting) career, that has seen him progress from graduate software engineer to board director, Rowe has ‘worked for about thirty different bosses’, who in turn have served in the management food chain under their bosses, and so on. With this much leadership expertise influencing the way things are done, there must be high quality findings to be extrapolated, suggests Rowe. With ‘Positive People Leadership’ we have exactly that. Not only has Rowe learned from every manager he’s reported…

  • The bigger picture: Czinger 21C hypercar

    To build the car, which has 1250 horsepower (1350 with an upgrade) and a top speed of 253mph in optional low-drag V Max configuration, Czinger used its in-house 'Human-AI' production system and 3D-printing technology. Each component is manufactured using this technology and is computationally engineered using AI, optimised for weight and performance, and carefully finished by hand. The system can even switch from creating a rear frame to a full chassis with only a software change. Image credit: Cover Images Although it will only have an initial production run of 80, Czinger chiefs hope the 21C will be the first in a series of exclusive performance vehicles. With 1250hp and a dry weight under 1240kg, the 21C claims a true 1:1 power-to-weight ratio. It also features…

  • Reclaiming reality in the digital age

    “We live at a time when the pursuit of authenticity is more important to us than ever before,” says Alice Sherwood. It doesn’t matter what example you give, she adds, whether it be the trend for artisan food or the fight against the dissemination of disinformation, “it matters to us”. You can punch in an n-gram for authenticity on Google and discover that searches for the term are “going through the roof. And yet we seem to have created a world that is less authentic.” It’s a paradox that intrigues Sherwood, one that lies at the root of why she wrote her new book ‘Authenticity’ and subtitled it ‘Reclaiming reality in a counterfeit culture’. The word culture is important because, while her forensic dissection of swindles and skullduggery is built on the foundation of science, statistics and…

  • Disposable electronic components could be printed on paper

    A team at the State University of New York has devised a way of minimising e-waste, by developing disposable electronic components that can be printed on a sheet of paper.   They designed a paper-based amplifier-type circuit that incorporates resistors, capacitors and a transistor, which would be both easy to carry and to recycle.  The team first used wax to print channels onto a sheet of paper in a simple pattern. After melting the wax so that it soaked into the paper, the researchers printed semiconductive and conductive inks, which soaked into the areas not blocked by wax. Then, they screen-printed additional conductive metal components and cast a gel-based electrolyte onto the sheet. The final circuit was very flexible and thin, just like paper, even after adding the components. To…

  • Back Story: Abigail and Donna Otchere, ‘STEM careers allow you to make a substantial, positive impact.’

    Shini Somara: What has it been like being women of colour in STEM? Donna Otchere: There are very few of us in engineering. I was one of two girls in my physics class and perhaps five people in my undergraduate degree who were from BAME backgrounds. I have always been driven by my love of maths and creativity, and engineering has always really interested me, so it was an obvious choice of career for me. Not relating to others, however, has made things harder, but if I don’t speak up for minorities in STEM this problem continues. I also witness so many misconceptions in engineering about who and what engineers are, and that must change too! Engineers are problem-solvers and that can be anyone. Abigail Otchere: I see more women than men in my field of biomedical science, but there are certainly…

  • UK government offers North Sea oil and gas licences despite climate concerns

    UK regulators on Friday began the 33rd round of offshore licences to enable companies to explore for oil and gas, prioritising four areas in the southern part of the North Sea, where gas has already been discovered. The process, which will run until the end of June, is the first since 2019-2020, when the government promised to design a “climate compatibility check” to ensure that the award of new permits was “consistent with the UK’s wider climate objectives”. At the time, the check was criticised because it is only advisory and does not restrict authorities from granting a licence, as they have now announced.  In a policy U-turn, the NSTA has confirmed nearly 900 locations are being offered for exploration, with as many as 100 licences set to be awarded in the most recent round, with…

  • Safety concerns as unqualified electricians found to be installing EV charge points

    The report, from the consultancy Pye Tait on behalf of the Electrotechnical Skills Partnership (TESP), said there was a concern that that “not all installers are sufficiently competent or qualified to undertake the job”. It states that many of those attending upskilling courses on how to safely install electric vehicle charge points ( EVCPs) are not fully qualified electricians, instead switching from other lower-skilled sub-sectors such as smart meter installations. These courses are designed only for fully qualified electricians as a bolt-on qualification, according to the report, and “this raises immediate concern around the safety and quality of EV charge points installed by these individuals, as well as broader concern about the potential “de-skilling” of the sector. The report appears…

  • Interview: Dr Zara Nanu, CEO, Gapsquare

    When the World Economic Forum announced in 2015 that “we are 217 years away from closing the gender pay gap”, Dr Zara Nanu decided that something needed to be done about it. At the same conference, she heard that by 2030 most of us will be in self-driving cars. “I also heard that Nasa was saying we’ll be waving people off to Mars.” The CEO of Gapsquare says it was hard to listen to these short-range technology predictions while realising “we’re still two centuries away from pay parity”. Gapsquare develops AI-based software that crunches employment data to address issues such as gender pay inequality, with Nanu seeing it as her mission “to help organisations put a stop to biases and prejudicial practices preventing equality”. In recognition of her achievements, Nanu received an MBE in the…

  • Human rights lawyer calls for ‘total rewrite’ of Online Safety Bill

    Dr Susie Alegre has written a legal opinion piece warning that the UK government's proposed nternet safety laws fail to address the root causes of online harm, while also damaging free speech.  The article was commissioned by the consumer campaign group SumOfUs.  “The Online Safety Bill is a mess and needs a total rewrite. As it stands, it offers the worst of both worlds,” Alegre said. “It not only threatens free speech, freedom of expression and privacy, but fails to do enough to tackle the real drivers of online harm, such as social media companies actively recommending posts about self-harm, which contributed to the tragic suicide of teenager Molly Russell.” The Online Safety Bill has been presented by the government as a ground-breaking law that will protect the privacy and safety…

  • Letters to the editor: volume 17, issue 10

    Water, water everywhere... The BBC’s ‘Countryfile’ programme recently covered the Archimedean screw hydro-​turbine set into the weir on the River Thames at Windsor, which supplies the Castle. The question this raises is why every weir on all our rivers isn’t being equipped with this ancient piece of technology, coupled with more modern generating equipment. There are dozens of disused mills all over the country with the basics still in place – a wheel housing and wheel house, the infamous mill pond, usually the size of a small reservoir and with close access to the local electrical infrastructure. The obsession with planting thousands of acres of high-​quality farmland with solar PV cells that by their very nature have short life spans and are high maintenance – they need cleaning at least…

  • Money & Markets: The UK’s financial woes were down to the US Federal Reserve

    Engineers will be very familiar with chaotic processes. In some special types of configurations, tiny differences in starting points can lead to wildly different outcomes. Small inputs can lead to giant unpredictable results. Poincaré predicted planet trajectories and won a prize, only to find a mistake in his work and realise he had actually proved it was nigh on impossible to predict them through what was to become the foundation of Chaos Theory. It turns out that economics is one such system of moving bodies and while you might have a theory that works for now or perhaps one that fits the soon to change cyclical observations, things will decouple and land everyone in a fundamentally changed economic system. The old joke goes, ‘If a butterfly in the Sahara can cause a hurricane in the…

  • Engineers nanoprint electrodes to help treat neurological disorders

    The CMU Array could be used in brain-computer interface platforms, to  transform how doctors are able to treat neurological disorders. 3D-printed at the nanoscale, the ultra-high-density microelectrode array (MEA) is fully customisable. This means that one day, patients suffering from epilepsy or limb function loss due to stroke could receive personalised medical treatment optimised for their individual needs. To develop it, the Carnegie Mellon University team applied a novel microfabrication technique, Aerosol Jet 3D printing, to produce arrays that solved the major design barriers of other brain-computer interface (BCI) arrays.  “Aerosol Jet 3D printing offered three major advantages,” Rahul Panat, associate professor of mechanical engineering, explained. “Users are able to customise…

  • Opec+ to cut oil production to boost prices against US advice

    Energy ministers of the Organization of the Petroleum Exporting Countries (Opec) and allies have announced their countries will cut the amount of oil they produce by two million barrels per day – the equivalent of 2 per cent of global supply – in a decision expected to rise petrol prices all around the world.  The group said the cuts, which will come into place in November, were based on the “uncertainty that surrounds the global economic and oil market outlooks”.  The announcement marks the biggest reduction by the group since the height of the pandemic in 2020. Since then, Opec nations  have been gradually unwound those record cuts. However, they have now taken the opposite approach, as to address the recent fall in oil prices, caused by the slowing down of the global economy.  “We…

  • Neeva search engine launches in Europe to rival Google, with zero tracking or ads

    Neeva has already acquired over 600,000 users in the US, following its 2021 launch, and is now bringing its platform to the UK, with its aim of offering users greater control over search and delivering honest results. Founded by Sridhar Ramaswamy, an ex-senior vice president of advertising at Google, and Vivek Raghunathan, an ex-vice president of monetisation at YouTube, Neeva claims to be "reinventing web search for good", challenging Google’s web-search dominance. Neeva’s European expansion follows a successful 2021 $40m 'Series B' funding round. The intention with Neeva is to put users first and give consumers control to customise their web search experiences. By eschewing ads and advertisers, Neeva eliminates the corporate bias that has increasingly plagued the traditional search experience…

  • Air pollution particles can reach babies in the womb, study finds

    The team from the University of Aberdeen in Scotland, and Hasselt University, Belgium, said their findings were “especially concerning” because key organ development occurs when foetuses are growing in the uterus. Researchers examined 60 mothers and their babies in Aberdeen and the Grampian region in Scotland. They also analysed tissue samples from 36 aborted foetuses between seven and 20 weeks of gestation. The team found evidence of “black carbon particles” – also known as soot particles – in umbilical cord blood, which shows that the particles can cross the placenta. Such soot particles were present in all mothers and newborns. According to the researchers, the level of particles found was linked to the amount of air pollution the mother was exposed to during pregnancy. The research…

  • Former Uber security chief found guilty of covering up massive data breach

    Joe Sullivan, Uber's former  security chief, has been convicted of a count for concealing a massive hack suffered by the ride-hailing company in 2016, as well as another related to obstructing a Federal Trade Commission investigation into the breach. Sullivan was fired in 2017 over the incident, which was said to have affected the personal data of over 57 million customers and drivers. He is now facing up to eight years in prison.  According to the criminal complaint,  Uber paid the hackers $100,000 (£ 88,670) in Bitcoin in December 2016, through a 'bug bounty' program that rewards developers for revealing security vulnerabilities. Sullivan wanted them to sign non-disclosure agreements promising to keep mum about the affair, prosecutors said, stressing that he had taken steps to make…

  • Hands-on review: Zumy webcam laptop light

    While the Covid-driven days of full-time WFH are largely behind most of us, the hybrid nature of work now still means a lot of video calls and meetings from home. For many of us, this means finding a suitable home office space in which to participate in these virtual gatherings, a place in our homes where the crucial crossovers of comfort, good Wi-Fi and flattering lighting best align. If you can tick the first two, but sometimes struggle with the third, the Zumy webcam laptop light could be just what you need. While there are (plenty of) other fill-light options out there, the Zumy has a few neat tricks up its foldable sleeve that may sweeten its appeal. Initiated as an Indiegogo campaign in December 2020 – perhaps understandably, during the peak period for pandemic lockdowns – Zumy…

  • Three scientists win Nobel Prize for ‘click Chemistry’

    Professor Carolyn R Bertozzi from Stanford University, Professor Morten Meldal from the University of Copenhagen, and Professor K Barry Sharpless from Scripps Research, have received the coveted Nobel Prize " for the development of click Chemistry and bioorthogonal chemistry”. The three will share the  10 million Swedish krona (£800,000) award.  The work reportedly "transformed" how chemistry can be done, making it simpler and more effective, by allowing molecules to link together, like Lego pieces. Moreover, their work can also ensure that many reactions can be done with minimum impact on the environment.  This would be the second Nobel Prize awarded to Sharpless, who received this award for the first time in 2001 for chiral catalysts. Bertozzi, who pioneered bioorthogonal chemistry…

  • Hands-on gadget review: Osprey Transporter waterproof duffel

    This duffel bag is cute and lightweight but what sets it apart from the pack is the waterproofing. It’s billed as waterproof luggage, with welded seams and a waterproof zip. It’s available in three sizes: 40 litres (£220), 70 litres (£250) and 100 litres (£270), so it’s not cheap. But it’s not your average bag. It’s IPX7 rated. This is rare for a dry bag and means it’s been tested to be submersible 1m deep for 30 minutes. I tested the mid-sized, 70 litre Transporter Duffel WP 70 in a colour called Mars Orange. In the photos it looks glossy red but it is definitely orangey. The other colour is called Tunnel Vision Grey but is nearly black. The first thing I noticed on unpacking was how ridiculously light the bag is. This 70-litre bag weighs just 1.12kg. That matters when it’s on your back…

  • Biden proposes an artificial intelligence ‘Bill of Rights’ blueprint

    Joe Biden's administration has unveiled a new AI Bill of Rights , which outlines five protections internet users should have in the AI age. The guidelines do not set out specific enforcement actions, but are instead intended as a call to action for the safeguarding of digital and civil rights in an AI-fuelled world, officials said. These can include algorithms used for recruitment or financial decisions that discriminate against women or people of colour, which has not been an uncommon occurrence.  The Bill of Rights lays out five principles that should guide the design, use and deployment of automated systems. These state that AI should be safe, should not discriminate, should violate data privacy, should not be used without the user's knowledge and consent, and should not be the only…

  • Elon Musk offers to buy Twitter for $44bn, again

    Elon Musk has offered to buy Twitter for $44bn (£38.3bn) for the second time this year.  In a letter sent by Musk's attorneys, the billionaire's intention to move ahead with the original deal was confirmed, pending receipt of the financing and an end of the legal fight. The news comes just two weeks before the two sides were scheduled to meet in Delaware's Court of Chancery, on October 17, where Twitter was preparing to sue Musk to either complete the deal or pay the previously agreed $1bn penalty for reneging on the deal.  “We received the letter from the Musk parties which they have filed with the SEC," said a Twitter spokesperson. "The intention of the company is to close the transaction at $54.20 per share." The announcement is the latest twist in a long-running saga after the world…
