AI-trained CCTV in rivers can spot blockages and reduce floods
Machine learning-equipped camera systems can be an effective and low-cost flood defence tool, researchers show Smart CCTV systems trained to spot blockages in urban waterways could become an important future tool in flood prevention, new research published today has found. Researchers at the University of Bath have shown that their AI-enabled detection software, 'AI on The River' trained to accurately detect natural debris, litter or waste blocking trash screens mounted in culverts, can be integrated to existing CCTV systems to provide an early warning of likely flooding.

Hampstead Heath ponds where dogs swim contaminated with pesticides
Most dog owners didn't know that flea and tick treatments are dangerous to aquatic life, suggesting more awareness could ease the problem. A study on Hampstead Heath shows that ponds where dogs are allowed to swim contain levels of two pesticides harmful to invertebrate life. These pesticides, imidacloprid and fipronil, are used as parasite treatments for flea and tick infestations in cats and dogs, using 'spot-on' formulas and flea collars.

Historical insecticide use linked to new resistant mutation in nearby mosquitoes
Scientists have discovered the first cases of Anopheles funestus mosquitoes genetically mutating to develop a resistance to a type of insecticide called DDT. The discovery of 'knock-down resistance' (kdr) - a major insecticide resistance mechanism in insect pests - is the first time such a mutation has been documented in this species, which is a major vector for malaria transmission in Eastern and Southern Africa.

Ultra-powered MRI scans show damage to brain’s ’control centre’ is behind long-lasting Covid-19 symptoms
Damage to the brainstem - the brain's 'control centre' - is behind long-lasting physical and psychiatric effects of severe Covid-19 infection, a study suggests. Using ultra-high-resolution scanners that can see the living brain in fine detail, researchers from the Universities of Cambridge and Oxford were able to observe the damaging effects Covid-19 can have on the brain.

Research breakthrough could enable future generations of self-sensing materials
Breakthrough research that eliminates the guesswork in developing advanced 3D printed materials could help accelerate the development of new forms of 'self-sensing' aeroplanes, robots, bridges and more. A team of engineers led by researchers from the University of Glasgow have developed the first system capable of modelling the complex physics of 3D-printed composites capable of detecting strain, load, and damage using nothing more than a measure of electrical current.

Baby boomers living longer, but in poorer health than previous generations
Baby boomers - those born in the late 1940s and 50s - are more likely to experience multiple health problems in their later years than their older counterparts, finds a study led by UCL researchers. In the paper, published in Journals of Gerontology, researchers from the UCL Centre for Longitudinal Studies and the University of Oxford found that rates of chronic disease, obesity and disability had increased across successive generations in England, the USA and Europe during the 20th century.

Only a quarter of millennials who want children are trying for them
Two fifths of 32-year-olds in England want children - or more children, if they are already parents - but only one in four of them are actively trying to conceive. A new report, published today by the UCL Centre for Longitudinal Studies, shows that more than half of this generation have already become parents, and half of those without children would like to start a family.

COVID-19 human challenge study highlights small changes to memory and cognition
An Imperial-led study has highlighted specific changes associated with COVID-19 in particular brain function scores of healthy young people. New analysis from Imperial's human challenge study of COVID-19 has revealed subtle differences in the memory and cognition scores of healthy volunteers infected with SARS-CoV-2, which lasted up to a year after infection.

Celebrities and politicians are climate change ’missing link’
Celebrities and politicians leading by example could be a crucial 'missing link' in climate change mitigation, finds new research. Psychologists from Cardiff University have uncovered new insights into the role of celebrities and politicians in influencing public opinion on low-carbon lifestyles. "Behaviour change is essential for reducing greenhouse gas emissions quickly.

GP practices in wealthiest areas of Wales receive more funding than deprived areas
There is an urgent need to restore fairness in the funding for GP practices in Wales, finds new research by Cardiff University. A new study has found that current funding levels for GP and primary care services are unfair - with practices based in some of the poorest areas of Wales with the highest patient demand receiving less money than those in the most affluent areas.

Water fluoridation less effective now than in past
The dental health benefits of adding fluoride to drinking water may be smaller now than before fluoride toothpaste was widely available, an updated Cochrane review has found. The team of researchers from the Universities of Manchester, Dundee and Aberdeen reviewed the evidence from 157 studies which compared communities that had fluoride added to their water supplies with communities that had no additional fluoride in their water.

British adults healthier in midlife than US peers
Rates of obesity, high blood pressure and high cholesterol are lower among British adults in their 30s and 40s compared to their counterparts in the US, according to a new study led by UCL researchers. However, people in Britain are more likely to be regular smokers and to judge their health as poor.

Worldwide study links environment to women’ quality of life
A global study has revealed that how women view their own home conditions, financial resources, and physical environment, including pollution levels, is key to understanding their overall quality of life and health. The study published today (2/10/24) in the open-access journal PLOS ONE was led by researchers from The University of Manchester and University Alberta, in collaboration with colleagues world-wide.

Cutting corners results in rare genetic diseases being undiagnosed, say scientists
Inaccurate naming of genetic diseases is resulting in some rare genetic diseases needlessly being undiagnosed, University of Manchester scientists warn. The Nature Genetics communication paper , published today (02/10/24 have throws into sharp relief existing data that around 6,000 UK children a year with rare illnesses never receiving a diagnosis, many dying without knowing what caused them The researchers also emphasise existing research that calculates the cost of pursuing lengthy diagnostic journeys rare genetic diseases to the NHS is over £3 billion per decade.

Four factors linked to higher infant mortality rates in deprived areas
Researchers have identified four key factors which together account for more than one third of inequalities in infant mortality, when comparing the most and least deprived areas of England. The new research, led by the University of Glasgow and published in the Lancet Regional Health Europe, highlighted the stark differences in infant mortality rates across the country, with rates in the most deprived areas in England more than double that of the least deprived areas in the first two decades of the 21st century.

’Missing link’ gamma-ray radiation from thunderclouds discovered
Groundbreaking research that used a NASA-equipped plane to fly over thunderclouds has described a new kind of radiation New research into the causes of lightning strikes, which could lead to better understanding and real-time forecasting of thunderstorms in the future, has been released today. Two studies published in Nature conclude that gamma ray generation from thunderstorms may be more common and take more forms than previously thought.

Cool roofs could have saved lives during London’s hottest summer
As many as 249 lives could have been saved in London during the 2018 record-setting hot summer had the city widely adopted cool roofs, estimates a new study by researchers at UCL and the University of Exeter. The paper, published in Nature Cities , analysed the cooling effect that roofs painted white or other reflective colours would have on London's ambient temperature between June and August 2018, the city's hottest summer.
