Russian troops have placed "objects resembling explosives" on roofs at the Zaporizhzhia nuclear power plant (ZNPP), Ukrainian President Volodymyr Zelensky said in a video address Tuesday that instantly sparked concerns around the world.

It feels like every day there’s a science story that comes along ready to blow our tiny minds, and today is no exception. A series of ancient interconnected cities have been discovered in the remote El Mirador jungle Guatemala, and it’s changing our entire understanding of the ancient civilisation. More than 400 settlements have been uncovered with some dating back as far as 1,000 BC. They’re linked by roads too, and it’s led them to be described as “the first freeway system in the world”. Sign up to our free Indy100 weekly newsletter Richard Hansen, a research professor at the University of Idaho, is an expert on the project and he’d called the findings a “game-changer”. It was previously thought that the Mayan peoples were nomadic, but these cities have changed the scientific community’s understanding. Speaking to the Washington Post, Hansen said: "We now know that the Preclassic period was one of extraordinary complexity and architectural sophistication, with some of the largest buildings in world history being constructed during this time.” On top of the 110 miles of interconnected roads, the discoveries also showed evidence of organised agriculture and even hydraulic systems. The findings are the result of work which first began in 2015, which saw lidar technology uncovered signs of ancient structures below the surface. Archaeologist Enrique Hernández, from San Carlos University said about the findings: “Now there are more than 900 [settlements]… We [couldn’t] see that before. It was impossible,” he said.

Playing with dolls could help the social development of children - including those with neurodiverse conditions such as autism, according to a study. The research, from Cardiff University, found children exhibiting higher levels of autism traits showed increased brain activity in a key region associated with social processing when engaging in conversations with individuals during doll play. The new findings suggested that broader social engagement with others while engaging in doll play was a unique pathway to social development for these children. This was in contrast to what was observed in neurotypical children, who were more likely to discuss the dolls’ thoughts and emotions. However, researchers said that despite this difference, it showed that both groups may be able to benefit from doll play by using it as a tool for practising social scenarios and developing social skills, such as empathy. The findings are the latest release from a multi-year study by the Centre for Human Developmental Science at the university’s School of Psychology. Previous years have focused on neurotypical children and found wide-ranging social and developmental benefits of playing with dolls. Now, in its third year, the research team has replicated those results with a more diverse range of participants, including children aged between four and eight displaying both high and low levels of traits associated with autism. Lead researcher Dr Sarah Gerson said: “Our study shows that doll play can encourage social processing in children, regardless of their neurodevelopmental profile. “The findings show that all children, even those who display neurodivergent traits commonly associated with autism, may use doll play as a tool for practicing social scenarios and developing social skills, such as empathy.” State-of-the-art functional, near-infrared spectroscopy equipment was used to explore brain activation while children played with dolls and on tablets, both by themselves and with another person, replicating conditions from the first year of the study. While observing children, researchers saw increased brain activity in the posterior superior temporal sulcus (pSTS) region - which is heavily involved in social and emotional processing such as empathy - when playing with dolls, for both play with a social partner and during solo doll play, but less so during solo tablet play. The study’s results suggest that doll play could support social processing, regardless of a child’s neurodevelopmental profile, but through different pathways. For children displaying fewer autistic traits in the research, talking about the mental states and emotions of the dolls they were playing with was associated with increased pSTS activity. In contrast, for those displaying more autistic traits, talking with others during doll play, even when playing by themselves, led to more social processing on a neural level. Other research has shown that social processing and empathy skills are important determinants in children’s future emotional, academic, and social success. The study was a collaboration with the Wales Autism Research Centre. ‘Create a more inclusive and supportive environment for their development’ Its director Dr Catherine Jones said: “The study reinforces how it is important that that we acknowledge and value neurodiversity. “This means recognising and valuing the diverse ways in which children’s brains work and approaching social development in a way that is inclusive and accommodating for all children, regardless of their neurodivergence. “By embracing all ways that children choose to play, we can create a more inclusive and supportive environment for their development.” Since the landmark publication of Piaget’s theory of cognitive development, the effects of play have been thought to be positive for kids’ social skills and creativity, but this has never been scientifically evidenced at the brain level. The multi-year long-term study, commissioned by Barbie, is the first time key Piaget theories on play have been scientifically evidenced via brain imaging and the first to use neuroimaging evidence with natural doll play, meaning there was no prescribed storyline to show how the brain is activated during doll play. Michael Swaisland, head EMEA of insight and analytics, Mattel, said: “We are proud to know that when children, regardless of their neurodevelopmental profile, play with Barbie, their playtime may benefit their development. “As Barbie continues to inspire the limitless potential in every child, we are delighted to know, through neuroscience, that playing with dolls may encourage the development of social skills such as empathy in children, including those who display neurodivergent traits commonly associated with autism. “We look forward to uncovering even more benefits of doll play through our long-term partnership with Cardiff University as we look to shine a light on the benefits the play pattern has towards development, that parents might not have been aware of.” Parents and caregivers can visit here to learn more about the research and access resources.

Federal prosecutors have indicted President Joe Biden’s son Hunter Biden on three charges stemming from allegedly false statements in the purchase of a firearm following a special counsel investigation. The indictment – the first ever against a sitting president’s son – follows a failed plea agreement on tax and gun charges that collapsed in July under scrutiny from a federal judge. Charges announced on 14 September follow a multi-year investigation from David Weiss, who was appointed by Donald Trump and remained as US attorney for Delaware under the current administration in an apparent effort to avoid the appearance of a conflict of interest. Mr Weiss, whose investigation preceded the Biden administration and Biden campaign, was appointed as special counsel in August. Hunter Biden was set to plead guilty to misdemeanour tax charges and enter a diversion agreement related to a felony gun charge in July, but the agreement appeared to hit a snag during a federal court hearing, and the judge presiding over the case ultimately rejected the arrangement. Congressional Republicans, meanwhile, continue to investigate the younger Biden and prepare an impeachment inquiry against the president, fuelled by GOP allegations that he was involved with and profited from his son’s business dealings. House Republicans have not provided any evidence that the president was influenced by or profited from such dealings while in office. A Delaware grand jury’s indictment charges Hunter Biden with illegally owning a gun as a drug user, and for allegedly lying on a form when he bought the firearm. The charges are expected to draw right-wing outrage and fuel Republican campaigns against the Biden family, as the frontrunner for the 2024 Republican nomination for president faces four criminal indictments spanning dozens of charges, including for crimes allegedly committed while in office. The day before the indictment was announced, attorneys for Hunter Biden sued a former Trump-era White House official accused of launching a “sustained, unhinged and obsessed campaign” against him and the Biden family, including hacking the alleged contents of a laptop that were central to political campaigns surrounding the 2020 presidential election, federal investigations and Republican-led congressional probes.
