Are your grandparents up very early in the morning, without fail? Well, it turns out there are scientific reasons why older people wake up earlier as they get older. It’s been revealed that in later life, the natural process of ageing leads to changes in the times the body approaches sleep. According to HuffPost, our approach towards resting and amount of sleep we require is down to both genetics and our age. Cindy Lustig, who is a professor of psychology at the University of Michigan, said: “Like most of the things that change with age, there’s not just one reason, and they are all interconnected.” Sign up to our free Indy100 weekly newsletter It’s all to do with the brain becoming less responsive as people age to factors such as sunlight, social cues and physical activity which indicate where in the day we are at any given time. “The wiring of the brain is likely not sensing... and responding to the inputs as well as it should because it’s an ageing brain,” Dr. Sairam Parthasarathy, the director of the Center for Sleep and Circadian Sciences at the University of Arizona Health Sciences, also told the publication. “These are all what we call time givers, or they give time to the brain,” he said. In other words, they help the brain sense where it is in the 24-hour circadian cycle. Younger people can more easily connect indicators like eating dinner with the idea of sleeping in the next few hours. However, that’s not as easy for older people to register naturally, especially as their vision tends to suffer in later life. “Interestingly, one of [the reasons] seems to be that the vision changes that come with age reduce the intensity of the degree of light stimulation that our brain receives, which plays an important role in ‘setting’ our circadian clock and keeping it on track,” said Lustig.

It’s not quite the lost city of Atlantis, but scientists have just uncovered a slice of history that had been swallowed up by the sea. Experts admitted that even they were surprised when divers unearthed a 7,000-year-old stone road that had lain buried under layers of sea mud. The ancient structure was discovered after archaeologist Igor Borzić, of the University of Zadar, spotted “strange structures” nearly 16 ft (5m) underwater in the Bay of Gradina, off the coast of Croatia. The submerged road once linked the island of Korčula to an artificial, prehistoric settlement that belonged to a maritime culture known as the Hvar. Sign up for our free Indy100 weekly newsletter The university released footage of the incredible finding over the weekend. It showed the passageway which consisted of stacked stones and measured some 12 ft (around 4m) across. Archaeologists believe people walked this road “almost 7,000 years ago”, with radiocarbon dating of wood near the site suggesting the settlement may have been built around 4,900 BC. “In underwater archaeological research of the submerged neolithic site of Soline on the island of Korčula, archaeologists found remains that surprised them,” the University of Zadar said in a Facebook statement. “Namely, beneath the layers of sea mud, they discovered a road that connected the sunken prehistoric settlement of the Hvar culture with the coast of the island of Korčula.” Borzić and his team also discovered another “almost identical” settlement on the other side of Korčula Island. Neolithic artefacts including a stone axe, cream blades and sacrificial fragments, were found at the site which lay at a depth of 4-5m. Understandably, the researchers were delighted and, as they continue to delve into their nation’s past, we wonder what else they’ll unearth. Have your say in our news democracy.

A South Korean firm has announced the world’s first production line for perovskite-silicon tandem solar cells, which promise an increase in efficiency of between 50-75 per cent compared to standard solar panels. The commercialisation of solar cells that use perovskite follows years of breakthroughs with the mineral, which has been hailed as a ‘miracle material’ for its potential to transform various industries, including renewable energy. Seoul-based Qcells said it will invest $100 million to roll out the next-generation solar cell technoloy, which until now has been limited to lab tests and academic research. The investment will fund a pilot production line at a factory in Jincheon, which is projected to be operational by late next year. “This investment in Jincheon will mark an important step in securing technological leadership,” said Qcells CEO Justin Lee. “With a global R&D network spanning from Korea, Germany and the US, Qcells will ramp up its efforts to produce high-efficiency advanced tandem cells.” Tandem solar cells are able to improve the efficiency of standard solar panels by splitting the light spectrum and optimising the harvesting of energy from each section into electricity. The current world record for solar cell efficiency is 32.5 per cent – meaning nearly a third of solar radiation is converted into eletrical energy – which was achieved with a perovskite-silicon tandem cell in December. By comparison, traditional silicon-based solar cells are currently only capable of reaching around 22 per cent efficiency. Qcells has so far succeeded in developing a tandem perovskite solar cell with a 29.3 per cent efficiency, which was achieved earlier this year in collaboration with German research centre Helmholtz-Zentrum Berlin. The results were verified by the US Department of Energy’s National Renewable Energy Laboratory (NREL) Read More Microsoft makes world first nuclear fusion energy deal Quantum computer discovers bizarre particle that remembers its past Nasa says Jeff Bezos will build moon lander to take astronauts to the Moon ChatGPT app launches for iPhone users amid scam frenzy Google to delete Gmail and Photos accounts in huge purge

Scientists have revealed they had found a way to combine the technology of brain scans and artificial intelligence to transcribe “the gist” of people’s thoughts. Alex Huth, an assistant professor of neuroscience and computing science at the University of Texas at Austin, and a co-author on the new study published in Nature Neuroscience, said that ‘this is a real leap forward.’ The study was led by Huth and Jerry Tang, a doctoral student in computer science. The main development from this study is that it’s non-invasive. This means that subjects do not require surgical implants. Instead, brain activity is measured using a functional magnetic resonance imaging (fMRI) scanner. Sign up to our free Indy100 weekly newsletter In the study, individuals listened to hours of podcasts in the scanner. Then, given the participant’s consent to have their thoughts decoded, they listened to a new story and the machine-generated corresponding texts from brain activity. It’s not a word-for-word transcript. For example, when an individual heard the phrase ‘I don’t have my driver’s licence yet’, the model decoded the individual’s thoughts to read as ‘she has not even started to learn to drive yet.’ Even when participants thought up their own stories, the machine was able to decode their thoughts still. Tang acknowledged that the advancements made in the study had the potential for negative aftermath. Tang said, ‘we take very seriously the concerns that it could be used for bad purposes and have worked to avoid that.’ They ran tests that highlighted that unless the machine had been trained on an individual’s particular brain activity, it could not decode its thoughts. An individual had to allow for the machine to train their brain activity over a long period of time inside a fMRI scanner for it to work. Researchers also found that it was easy to ‘sabotage’ the machine. Three participants were told to tell a different story in their mind, or count by seven, while listening to one of the podcasts. The study highlights even more development with artificial intelligence, after the popularity of OpenAI’s Chat GPT has sparked debate around the potential of AI. Have your say in our news democracy.
