Archaeologists find evidence of 'some of earliest humans in Scotland'
Stone tools found on the island off the west coast date back to around 9500-9000 years ago – the Late Upper Palaeolithic (LUP), experts believe.
Discoveries also include an 'enigmatic group of stone circular structures' which appear to be below modern-day sea level.

Local archaeologist Martin Wildgoose and Karen Hardy, a professor of prehistoric archaeology at the University of Glasgow, made the discoveries which confirm that early humans ventured further north than previously thought.
The finds have been announced in a paper – At the far end of everything: A likely Ahrensburgian presence in the far north of the Isle of Skye, Scotland – published in The Journal of Quaternary Science.
Professor Hardy said: 'This is a hugely significant discovery which offers a new perspective on the earliest human occupation yet known of north-west Scotland.'

During this period, which is immediately after the Younger Dryas (also known as the Loch Lomond Stadial), when much of west Scotland was buried under ice, groups of nomadic hunter-gatherers most likely of the Ahrensburgian culture from northern Europe, crossed Doggerland, an area that is now covered by the North Sea, and established themselves on Skye.
Ahrensburg was a late Paleolithic culture of reindeer hunters in northern Europe, known for their distinctive tanged flint points and mobile way of life as the Ice Age ended.
The ancient stone tools found on the Isle of Skye (Image: Karen Hardy) Hardy went on: 'The journey made by these pioneering people who left their lowland territories in mainland Europe to travel northwards into the unknown is the ultimate adventure story.
'As they journeyed northwards, most likely following animal herds, they eventually reached Scotland, where the western landscape was dramatically changing as glaciers melted and the land rebounded as it recovered from the weight of the ice.
'A good example of the volatility they would have encountered can be found in Glen Roy, where the world-famous Parallel Roads provide physical testament to the huge landscape changes and cataclysmic floods that they would have encountered as they travelled across Scotland.'
Professor Karen Hardy (Image: Supplied) Wildgoose and Hardy's paper states: 'While the number of Ahrensburgian findspots is low, they are spread widely across Scotland, including from the islands of Tiree, Orkney and Islay, that also imply significant sea journeys, suggesting a larger population than the number of finds might imply.
'To date, all Late Upper Palaeolithic (LUP) sites in Scotland have been discovered by chance, and there is insufficient evidence to address further questions regarding their adaptations and lifestyles.
'By reconstructing the geographical limitations imposed by ice sheet evolution, changes in Relative Sea Level (RSL) and river courses, it may be possible to focus on other likely locations – both onshore and offshore – and begin to uncover more evidence.'
The University of Glasgow said the exact location of the sites were not open to visitors, but that Sconser, on Skye, would provide an idea of how the landscape looked when those early settlers were alive.

Domestic violence can affect victims' brain health for life, study suggests
Women who are victims of domestic violence are at a higher risk of traumatic brain injury and mental health conditions for many years after the abuse has ended, a study has found. Almost one in three women around the world experience domestic violence, and researchers say the impact on mental health – such as post-traumatic stress disorder (PTSD) – can last for decades. The study, by the University of Glasgow and published in the journal BMJ Mental Health, explored the mental health consequences associated with domestic violence and traumatic brain injury. The paper – Intimate partner violence, traumatic brain injury and long-term mental health outcomes in mid-life: The Drake IPV study – looked at data from 632 participants aged between 40 and 59. Fourteen per cent reported having a history of domestic violence with physical abuse. Compared with unexposed participants, those with a history of intimate partner violence-physical abuse (IPV-PA) were associated with a higher exposure of traumatic brain injuries (TBI) and a higher lifetime and ongoing diagnoses of depression, anxiety, sleep disorders andPTSD. The analysis also found that even after an average of 27 years since exposure to IPV-PA, the risk of mental health disorders remained just as high. The study concluded: 'Among those reporting exposure to IPV-PA, the majority reported a history of repetitive blows to the head and mild TBI. A history of TBI, in turn, was associated with evidence of adverse mental health outcomes. 'These observations offer initial insights into the potential lifelong brain health consequences of intimate partner violence with physical abuse. 'Given the global prevalence of intimate partner violence, particularly among women, these findings highlight a pressing need for further research in this field, as well as for targeted interventions to raise awareness among policymakers and medical professionals about the potential impact of intimate partner violence with physical abuse on health outcomes across the lifespan.' The work was funded by the Drake Foundation, the National Institutes of Health, the Medical Research Council, NHS Research Scotland, the Alzheimer's Society, and the Alzheimer's Association. Prof Willie Stewart said: 'Given its prevalence, these findings highlight domestic violence as a public health issue with potential for long-lasting impacts on brain health. Our work also reinforces the need for more research in this previously neglected area.' Dr Graciela Muniz-Terrera, a co-author of the report, said: 'This study highlights the importance of including questions about domestic violence in population research to advance our knowledge about its long-term effects.'

Domestic abuse survivors face long-term consequences
A new study from the University of Glasgow explored the mental health consequences associated with domestic violence and traumatic brain injury, and suggested that the impact can last for 27 years after the abuse ends. The study, Intimate partner violence, traumatic brain injury and long-term mental health outcomes in mid-life: The Drake IPV study, is published in the BMJ Mental Health journal, and researchers said the issue had been 'neglected'. Using data from the multi-centre PREVENT Dementia Study, the researchers found that 14% of 632 study participants, women aged 40 to 59 at recruitment, reported a history of domestic violence with physical abuse. Compared with unexposed participants, domestic violence was associated with higher traumatic brain injury exposure, alongside higher lifetime and ongoing diagnoses of mental health disorders, such as depression, anxiety, sleep disorders and PTSD. The risk of ongoing mid-life mental health disorders remained, despite exposure to domestic violence having ceased on average 27 years before assessment, according to the research. A history of traumatic brain injury in those exposed to domestic violence was also associated with increased risk of ongoing PTSD symptoms and concurrent mental health disorders, the study found. The work was funded by the Drake Foundation, the National Institutes of Health, the Medical Research Council, NHS Research Scotland, the Alzheimer's Society, and the Alzheimer's Association. Professor Willie Stewart said: 'Given its prevalence, these findings highlight domestic violence as a public health issue with potential for long-lasting impacts on brain health.

Impact of domestic violence on mental health ‘can last for decades'
Women who experience domestic violence are at higher risk of traumatic brain injury and mental health conditions almost 30 years after escaping their abusers, a study suggests. Approximately 30% of women internationally experience domestic violence, however the impact on mental health including post-traumatic stress disorder (PTSD) can last for decades after physical abuse ends, research showed. A new study from the University of Glasgow explored the mental health consequences associated with domestic violence and traumatic brain injury, and suggested that the impact can last for 27 years after the abuse ends.
