A unique group of dogs helped the Inuit conquer the tough terrain of the North American Arctic, a major new analysis of the remains of hundreds of animals shows. The results of a major new study on the remains of Artic sledge dogs reveals that the Inuit brought specialised dogs with them when they migrated from Siberia over the Bering Strait into North America.

Women who spend longer periods of their early lives in less affluent neighbourhoods are at greater risk of experiencing violence during their early adulthoods at the hands of their intimate partners, finds a new study published in Epidemiology . Intimate partner violence - physical, psychological, or sexual violence committed by a current or former partner - is the most common form of violence experienced by women worldwide.

Research by Oxford University academics has found little evidence of a relationship between screen time and wellbeing in adolescents. Based on data from more than 17,000 teenagers, the study casts doubt on the widely accepted notion that spending time online, gaming or watching TV, especially before bedtime, can damage young people's mental health.

Planthopper bugs may be small, but they attract mates from afar by sending vibrational calls along plant stems and leaves using fast, rhythmic motions of their abdomen. Researchers at the University of Oxford describe how a newly-discovered "snapping organ" enables courting bugs of both sexes to produce this shaking motion through a combination of muscle action and elastic recoil.

The global prevalence of life threatening conditions in children and parents makes it an urgent priority to develop child-focused communication guidelines for healthcare professionals to support families in their time of need. Two new papers published in The Lancet , led by a team at the University of Oxford, highlight the importance of communicating with families about life threatening conditions in ways that can make a real difference to the traumatic circumstances in which families find themselves.

The first study of the impact of digital mobile devices on different aspects of family time in the UK has found that children are spending more time at home with their parents rather than less - but not in shared activities such as watching TV and eating. The increase is in what is called 'alone-together' time, when children are at home with their parents but say they are alone.

Academics led by Professor Lucie Cluver at Oxford University have shown how key services in lower and middle-income countries can contribute to multiple sustainable development goals (SDGs), even for the highest-risk children and adolescents. The study, led by Oxford University in collaboration with the universities of Cape Town and Witwatersrand, University College London and the United Nations Development Programme (UNDP), is the first to test the UN's concept of 'accelerators': provisions that can improve the lives of vulnerable populations in not only one SDG area, but many.

Researchers have developed a vaccine that blocks the effects of the main cause of pain in osteoarthritis (OA) - nerve growth factor (NGF) - in mice. In a collaborative effort between the Jenner Institute and the Kennedy Institute of Rheumatology at the University of Oxford, with colleagues in the University of Bern, and the Latvian Biomedical Research & Study Centre, scientists have developed and tested a vaccine that could be used to treat chronic pain caused by osteoarthritis, by blocking the cause of the pain - NGF.

The global population at risk from mosquito-borne diseases - including yellow fever, Zika and dengue - is expanding with changes in the distribution of two key mosquitoes: Aedes aegypti and Aedes albopictus . The spread of these species is largely driven by a combination of factors: human movements and climate change.

Researchers from the Department of Plant Sciences, University of Oxford, have discovered a new biochemical pathway in plants which they have named CHLORAD. By manipulating the CHLORAD pathway, scientists can modify how plants respond to their environment. For example, the plant's ability to tolerate stresses such as high salinity can be improved.

A major new radio sky survey has revealed hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. An international team of more than 200 astronomers from 18 countries, including researchers from the University of Oxford, has published the first phase of the survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope.

Growing meat in the laboratory may do more damage to the climate in the long run than meat from cattle, according to new research. In a first-of-its-kind study from the LEAP (Livestock, Environment and People) programme at the Oxford Martin School, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced.

Researchers in Oxford have carried out the world's first gene therapy operation to tackle the root cause of age-related macular degeneration (AMD), the UK's most common cause of sight loss. The procedure was carried out at the John Radcliffe Hospital by Professor Robert MacLaren, Professor of Ophthalmology at the University of Oxford, with the support of the NIHR Oxford Biomedical Research Centre in a clinical trial sponsored by Gyroscope Therapeutics, a UK-based company developing genetically-defined therapies for the treatment of eye diseases.

An unprecedented study of rabbit DNA spanning 150 years and thousands of miles has revealed the genetic basis for the animal's fightback - and ultimate triumph, against the deadly myxoma virus. The revelation of how rabbits evolved genetic resistance to myxomatosis through natural selection, comes as part of an international research collaboration, nearly seventy years after the lethal disease decimated species' populations of Australia, Britain and France.

Cannabis use among adolescents is found to be associated with increased risk of depression and anxiety in adulthood. Cannabis is the most commonly used recreational drug by teenagers worldwide. In Canada, among youth aged 15 to 19 years, the rate of past-year cannabis use is 20.6%, while in England, 4% of adolescents aged 11 to 15 years used cannabis in the last month.

Children of ethnic minority groups are over-represented for some types of Special Educational Needs (SEN) and under-represented for other types, compared to White British pupils, according to new Oxford University research. The report finds that: Asian pupils (Indian, Pakistani, Bangladeshi and Other Asian) are half as likely to be identified with Autistic Spectrum Disorders (ASD) as White British pupils Black Caribbean and Mixed White & Black Caribbean pupils are twice as likely to be identified with Social, Emotional and Mental Health (SEMH) needs as White British pupils.

Researchers at the Oxford Internet Institute, University of Oxford, have found no relationship between aggressive behaviour in teenagers and the amount of time spent playing violent video games. The study used nationally representative data from British teens and their parents alongside official E.U. and US ratings of game violence.

A team of researchers from the Medical Research Council (MRC) Weatherall Institute of Molecular Medicine at Oxford University has developed a new technique that allows scientists to reliably track genetic errors in individual cancer cells, and find out how these might lead to uncontrollable growth. Despite recognising that cancer cell diversity underlies treatment resistance and recurrence of cancer, previous attempts to track errors in individual cancer cells were very inaccurate, or could only track a few cells at a time.

Anthropologists at the University of Oxford have discovered what they believe to be seven universal moral rules. The rules: help you family, help your group, return favours, be brave, defer to superiors, divide resources fairly, and respect others' property, were found in a survey of 60 cultures from all around the world.
