A startup in China is set to begin production of ultra-efficient solar panels that are made from the so-called “miracle material” perovskite. The next-generation solar cells will be manufactured at half the cost of traditional silicon cells, with 50 per cent greater efficiency, according to researchers from Nanjing University who made the design breakthrough that made mass production possible. “The raw materials for making perovskite cells are cheap and abundant, making the production costs of these cells just one 20th of traditional solar cells,” Professor Tan Hairen from Nanjing University, told state media. “Moreover, they are easier to produce and can be made in a single factory. Even with other items added, the overall cost of production is only half of that of traditional silicon cells.” Professor Tan has created a startup called Renshine Solar to move forward with commercialisation of the technology, and has already signed a government deal to build a production line in Jiangsu province this summer. The factory is expected to achieve a capacity of 150 megawatts by September, according to the South China Morning Post, with the perovskite solar panels built for use on roofs, walls, or placed on electric cars to improve their range. The perovskite solar cells (PSCs) are capable of retaining over 90 per cent of their initial performance after 600 hours of continuous operation, the team noted, making them suitable for commercial use. The researchers said the next-generation solar cells could also be used in applications ranging from building-integrated panels to space-based electricity generation. “With their lower fabrication cost, low-temperature solution processability, roll-to-roll manufacturing, and wide-bandgap tunability, PSCs have the potential to become the candidate of choice for high-efficiency tandem solar cells,” they wrote in a study detailing the new design that will enter production. “Considering the rapid progress in photovoltaic performance, PSCs have been considered to be ideal candidates for integrating with other systems to realise new innovative technologies.” The study, titled ‘Next-generation applications for integrated perovskite solar cells’, was published in the scientific journal Nature. Its publication comes just one month after a South Korean firm announced that it was aiming to commercialise tandem perovskite solar cells following a $100 million investment to fund a pilot production line next year.

A spate of recent orca attacks has fuelled concern among scientists in recent weeks for animal safety, and even led to speculation that the ocean mammal could be trying to rise up against humans. But are they? In a new trend – dubbed "orca wars" by some on social media – a population of orcas has recently been smashing into boats off the coast of Portugal and near the Strait of Gibraltar at a rate of nearly one per day. That's according to researcher Rui Alves, who collects data on the attacks. In June alone there have been 12 orca attacks on boats and 12 other encounters. In May, there were 21 attacks, says his website, orca.pt. Sign up to our free Indy100 weekly newsletter Of course, social media reacted just how you might expect: by picking a team. One person tweeted: “If you an orca whale reading this, i am on your side. I have always been on your side.” Researchers don’t know exactly why this is happening, but there are two main hypotheses. The first is that killer whales – highly intelligent and social creatures – have invented a new fad, something that younger members of orca pods have been known to do. The other, more concerning possibility, is that it is a response to trauma involving a boat, Dr Alfredo López Fernandez, of Grupo Trabajo Orca Atlántica (GTOA, or Atlantic Orca Working Group), told the Guardian. “[It could be a] response to an adverse situation; one or several individuals have had a bad experience and are trying to stop the boat so as not to repeat it. This behaviour coincides with the profile of adults,” he said. If it is the latter, there is even one key suspect in starting the trend: a white orca called Gladis Blanca (or White Gladis), who is thought to have had a bad collision with a vessel at some stage. Other adult orcas in the region also have injuries consistent with boat collisions or entanglement, López added. “All this has to make us reflect on the fact that human activities, even in an indirect way, are at the origin of this behaviour,” he said. In fact, the attacks are not such a new thing. Back in 2020, a group of orcas were seen pursuing sailboats in the region, in an act of aggression that was previously thought to be extremely rare. Since then, it has grown more and more common. The orcas have tended to ram into the hulls of boats, but they have also been seen scraping them with their teeth. The attacks sometimes snap the boats’ rudders, leaving sailors unable to navigate. In three cases, the animals damaged a boat so badly that it sank. However, for all the concern that the orcas might be getting, erm, orca-nised, scientists remain concerned that the attacks could come back to bite the ocean mammals eventually. The Iberian orca subpopulation is considered critically endangered, according to GTOA, with only 39 animals the last time a full census was carried out in 2011. López and his colleagues fear boaters may lash out, or that the orcas might hurt themselves in the process of ramming the vessels. Either way, it doesn’t look like the attacks will stop any time soon. So who knows: maybe the ocean world really is rising up… Have your say in our news democracy.

Scientists have found that students who cut social media use to 30 minutes per day can see significant reduction in anxiety, depression, and loneliness, an advance that can lead to better mental health interventions. A growing body of research in recent years has shown that an increase in social media use among young people is linked to their declining mental health. Researchers at Iowa State University assessed this link further in a two-week experiment with 230 college students. Half of the participants were asked to limit their social media usage to 30 minutes a day, and received automated, daily reminders. The study, published in the journal Technology, Mind, and Behavior, found that this group of participants scored significantly lower for anxiety, depression, loneliness and fear of missing out at the end of the experiment compared to the control group. These participants also appeared to have a brighter outlook on life, scoring higher for “positive affect,” which the researchers describe as “the tendency to experience positive emotions described with words such as ‘excited’ and ‘proud.’” “It surprised me to find that participants’ well-being did not only improve in one dimension but in all of them. I was excited to learn that such a simple intervention of sending a daily reminder can motivate people to change their behavior and improve their social media habits,” study co-author Ella Faulhaber said. The psychological benefits from cutting back on social media was found to extend even to participants who sometimes exceeded the 30-minute time limit. Scientists suggest it is not about being perfect, but putting in the effort that makes the difference. While previous research has assessed the effects of limiting or abstaining from social media, many of the interventions recommended in these studies require heavy supervision and deleting apps or using special applications to block or limit social media use. “When a perceived freedom is taken away, we start resisting,” says Douglas A. Gentile, another author of the study, who adds that eliminating social media completely may take away some of its benefits like connecting with friends and family. For those looking to cut back on social media use, scientists recommend setting a timer to see how much time one spends on social media. “Recognize that it’s not easy to stick to a time limit. Social media apps are designed to keep you engaged,” researchers said in a statement. However, they urge people not to give up as limiting social media use over time has real benefits for daily life. “We live in an age of anxiety. Lots of indicators show that anxiety, depression, loneliness are all getting worse, and that can make us feel helpless. But there are things we can do to manage our mental health and well-being,” Dr Gentile said.
