Eight out of ten ginger cats are male. Now we finally know why
Marmalade-coloured cats are not the only orange-furred mammals in the animal kingdom, but scientists have discovered something that sets the tabbies apart from tigers, orangutans and even redheaded humans.
Only in domestic cats is the colour orange strongly linked to one sex, with males making up at least 80 per cent of ginger felines.
Researchers have now not only uncovered the gene responsible, but also the process that causes it to be linked so strongly to males.

A gene known as Arhgap36 is shared by many mammalian species, including humans, but it normally has no link to pigmentation. Instead, it helps to govern the relationship between the nervous and hormonal systems. Cancers have

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.'

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. 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.

Strawberry Moon 2025: When and how to see June's full Strawberry Moon
A full Strawberry Moon will appear in UK skies this week coupled with a rare phenomenon not seen in almost 20 11 June, stargazers in the northern hemisphere will be able to spot the full Moon sitting very low in the southern sky, making it appear much larger than by an event known as a 'major lunar standstill', the opportunity will not arise again until 2043. What is the Strawberry Moon and why is this one rare? The Strawberry Moon is the name given to the full Moon in June. It is named after the harvest season observed by indigenous Americans, signalling the time of year that wild strawberries were harvested, according to the Old Farmer's Almanac, moons were given nicknames to help keep track of time and monitor the changing full Moon is usually the lowest-hanging of the year in the Northern Hemisphere. It is likely to be exaggerated this month as a result of a 'major lunar standstill' which took place earlier this year - the effects of which can still be is when the Moon reaches the extremes of its orbit around the Earth, rising and setting at its most northerly and southerly positions on the horizon. It happens every 18.6 years and the effects are most visible during a full Moon. Another Moon this low is not expected until 2043. When and how to see it Tuesday night could be the best time to see the Strawberry Moon with clear skies in the forecast for parts of the UK. The Moon rises in the east and sets in the west just like the Sun. Don't forget you can find your local forecast on the BBC Weather App. Is the Strawberry Moon pink? It is true that the Strawberry Moon may appear to take on an apt reddish tinge. But that doesn't have anything to do with its position so close to the horizon means that the light it reflects towards Earth passes through the thicker, lower layer of wavelengths of light ('blue light') are scattered while longer wavelengths of light such as red reach our eyes, making the Moon appear red much like a colourful you manage to catch the Strawberry Moon on camera, why not share your photographs with BBC Weather Watchers.
