  • This Dutch Solar Car Lightyear 0 Could Drive for Months Without a Recharge

    The Lightyear 0 uses solar energy for more than 500km of driving range. Picture: SUPPLIED Is solar the next frontier for charging vehicles? Dutch company Lightyear One thinks so and has unveiled what it says is the world’s first production-ready solar car. The Lightyear 0 is a family sedan with solar panels built into the roof and bonnet, capable of generating up to 70km of charge-free driving a day. The Netherlands-made car isn’t totally sun-powered, and like a regular electric vehicle (EV), it has a battery that can be charged by plugging it in to a wall socket or public charging station for a claimed driving range of 710km on a single charge. The solar charging can contribute up to 10km of range per hour or up to 1.05kW of constant trickle charging. Over the course of a full summer's day, that can power up to 70km of driving, says Lightyear One. With a fully topped-up battery and the constant charging, Lightyear says that if you drive less than 50km daily, you can theoretically use the car for months without needing to charge it on a plug. The minimalistic interior of the Lightyear uses sustainable materials. Picture: SUPPLIED Helping to attain such impressive figures is the four-door coupe’s drag co-efficient of just 0.19, making it the most aerodynamic family car yet built. Part of that is thanks to specially developed Bridgestone tyres, designed to reduce rolling resistance. Some of the Lightyear 0’s efficiency stems from cutting back on performance levels in favour of a longer range. The car takes 10 seconds to accelerate from standstill to 100km/h, with a top speed of 233km/h, compared to many electric sports cars today that scorch to 100 km/h in under four seconds. The Dutch car is also practical, as it accommodates five passengers with plenty of space for luggage. The interior is crafted out of lighter plant-based leather, recycled PET bottles and rattan palm. It’s equipped with a 10.1-inch touchscreen. Only 946 units of the Lightyear 0 will be built and each will cost $266,000 (roughly R4.3m). Deliveries are scheduled to start in November 2021.

  • China Says It May Have Received Signals From Aliens

    Scientists have yet to rule out human radio interference as the signals' source The signals were detected by the 500-meter Aperture Spherical Telescope (FAST) located in southwest China's Guizhou Province. (Image credit: NAO/FAST) China is claiming that its enormous "Sky Eye" telescope may have picked up trace signals from a distant alien civilization, according to a recently posted and subsequently deleted report by Chinese scientists. Astronomers at Beijing Normal University have discovered "several cases of possible technological traces and extraterrestrial civilizations from outside the Earth," according to a report published Tuesday (June 14) in Science and Technology Daily, the official newspaper of China's Ministry of Science and Technology. The signals were picked up by China's Five-hundred-meter Aperture Spherical radio Telescope (FAST), nicknamed "Sky Eye," which is the largest radio telescope in the world. Sky Eye was put to work scanning deep space for radio signals that could indicate extraterrestrial life in 2019; sifting through that data in 2020, the researchers said they spotted two suspicious narrow-band, potentially artificial radio signals. Then, in 2022, a targeted survey of known exoplanets found another strange narrow-band radio signal, bringing the tally up to three. Related: 9 things we learned about aliens in 2021 As the signals are narrow-band radio waves typically only used by human aircraft and satellites, they could have been produced by alien technology. However, the scientists say their findings are preliminary and should be taken with caution until the analysis is complete. "These are several narrow-band electromagnetic signals different from the past, and the team is currently working on further investigation," Zhang Tongjie, head scientist at the China Extraterrestrial Civilization Research Group at Beijing Normal University, told the Science and Technology Daily. "The possibility that the suspicious signal is some kind of radio interference is also very high, and it needs to be further confirmed and ruled out. This may be a long process." Following its publication, the report quickly began to circulate on the Chinese social media network Weibo and was picked up by a number of other state-run outlets. The reasons behind its sudden deletion are unclear. The signals aren't the first time that scientists have been baffled by radio waves from deep space. In August 1977, a SETI (Search for Extraterrestrial Intelligence) search performed by the Ohio State University's Big Ear telescope picked up an incredibly strong, minute-long, electromagnetic burst that flared at a frequency scientists suspected could be used by alien civilizations. Upon spotting the signal on a data printout, the scientist working with the telescope that night, Jerry Ehman, hastily scribbled "Wow!" in red pen on the page, giving the detection its famous name. Follow-up searches in the same region of space have all returned empty-handed, and later research has suggested that the signal could have come from a sun-like star located in the constellation Sagittarius, Live Science previously reported. Nonetheless, the signal's source is still a mystery. Chinese astronomers are keen to rule out radio interference because it has famously waylaid alien-hunting scientists in the recent past. In 2019, astronomers spotted a signal beamed to Earth from Proxima Centauri — the nearest star system to our sun (sitting roughly 4.2 light-years away) and home to at least one potentially habitable planet. The signal was a narrow-band radio wave typically associated with human-made objects, which led scientists to entertain the exciting possibility that it came from alien technology. New studies released two years later, however, suggested that the signal was most likely produced by malfunctioning human technology, Live Science previously reported. Similarly, another famous set of signals once supposed to have come from aliens, detected between 2011 and 2014, turned out to have actually been made by scientists microwaving their lunches. Tonjie has added that his team is planning to take repeat observations of the strange signals to conclusively rule out any radio interference and obtain as much information about them as possible. "We look forward to the [FAST telescope] being the first to discover and confirm the existence of extraterrestrial civilizations," Zhang told the Science and Technology Daily. The discrepancy between the universe's scope and age and the apparent lack of intelligent life-forms beyond Earth — called the Fermi Paradox — has long troubled scientists. The paradox takes its name from the casual lunchtime musings of Nobel Prize-winning physicist Enrico Fermi, who, after contemplating the conundrum, is famously said to have remarked "so where is everybody?"

  • AI Could Mitigate Bias in Advertising Tech

    Significant changes are afoot in the advertising industry. In the last month alone, Netflix announced it may enter the ad business, lawmakers introduced bipartisan bills to throttle Google’s digital ad dominance and Facebook rolled out changes to help advertisers achieve more precision in their targeting. As major players prepare, advertisers have an opportunity to manage these changes in a way that optimizes ad spending and addresses the problem of bias in ad technology. Bias is a well-known issue for the ad industry, and the programmatic technologies the companies have adopted to supercharge marketing campaigns may not be improving matters. Nearly $1 trillion of digital media flows through programmatic engines that segment and target specific audiences, sometimes missing large consumer groups in the process. Not only can that contribute to improper bias, but it’s also an inefficient way to spend your ad dollars. It’s why, as an industry, we must tap into AI and leverage the powerful tools at our disposal to help mitigate the bias problem. As AI algorithms come to dominate in the industry’s efforts to find audiences and serve ads, we must integrate mitigation tools to avoid reinforcing biased thinking. That is, rather than letting AI exacerbate the problem, we must make the technology part of the solution. Doing this can help bring fairness by adapting ad buying behavior to reach more diverse audiences. By embedding fairness metrics and AI algorithms into the core of marketing processes, we can deliver a more effective value exchange between consumers and brands and potentially generate improved ROI on media dollars spent. Scaling fairness The technology needed to mitigate bias in ads already exists, and companies in finance, human capital management, healthcare, education and many other industries are testing open-source toolkits that build bias mitigation into their marketing processes. It’s time for the advertising industry to make a concerted effort to build fairness into our marketing technology as well. AI bias occurs when the machine learning process used to create AI models places certain privileged groups at a systematic advantage and certain unprivileged groups at a systematic disadvantage. Such bias could impact a financial institution’s ability to fairly assign credit scores or issue mortgages, or it could affect an insurance company’s ability to accurately predict medical expenditures for different clients. In advertising, bias can prevent consumers from being exposed to certain brands and information based on flawed algorithmic analysis. Often, this does harm to both the consumers and the brands. Embedding fairness metrics and AI algorithms into the marketing processes could enable the technology to, for example, automatically — and at scale — generate anomaly reports when something doesn’t look right with the data indexing as media plans are executing. If such a fairness solution can be applied to the core of how we do marketing today, we could not only help reduce bias, but also potentially help brands get a better return on their media spending. Open for businesses Addressing this problem is bigger than just one company. We need the best minds and resources in the marketing industry working together to address systematic bias in advertising. If our industry refuses to acknowledge the problem and fails to try to embed fairness into our core marketing processes and tools, then we could be facing a future dominated by ad platform consolidation, opaque metrics and automation-enhanced bias. An open, transparent approach to governance, AI and data sharing can help brands take back control of how they communicate with their audiences. Frankly, I don’t see how anyone in our industry can be aware of the potential bias problem and not be passionate about addressing it. It’s the right thing to do for society, in that you’re making information about products and services available to people who, because of bias, might not be exposed to those things. And it’s the right thing to do for brands, helping them better connect with a larger set of consumers that can help drive more business. I’m calling for an industry-wide effort encompassing every team, function, brand, agency and ad-tech provider. Leaders across the industry must commit to tackling bias together, if we are to make our industry better, more equitable, and more fit for the future.
