A cheap charcoal air filter can reduce nitrogen dioxide (NO2) inside vehicles by as much as 90%, compared to levels outside the vehicle. Research presented in a report by WM Air, the West Midlands Air Quality Improvement Programme at the University of Birmingham, shows that charcoal filters, which costs around £10-£20, can effectively remove NO2 from the air within vehicle cabins.
Mineral dust and Earth’s oxygen levels
Mineral dust played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, say researchers. Up to now, scientists have argued that oxygen levels rose as the result of photosynthesis by algae and plants in the sea, where oxygen was produced as a by-product and released into the atmosphere.

Baby formula manufacturers are marketing their products in ways that contravene guidance from the Department of Health and Social Care (DHSC), according to a new study by UCL researchers. The peer-reviewed study, published in the journal Public Health Nutrition , analysed the wording and images on 71 formula products available in UK supermarkets and pharmacies.
Testing a population for multiple genes at once will be limited in its ability to accurately predict disease risk, argues a new paper involving UCL's Professor Aroon Hingorani. DNA sequence commonly varies between individuals at many different points throughout the genome. Some of these genetic variants influence individual risk of common diseases such as dementia, cancer, diabetes, and cardiovascular disease, through effects on the expression or function of the encoded proteins.
Genetic test could guide use of cancer chemotherapy
A genetic test already used routinely in the NHS can guide the use of chemotherapy in people with bowel cancer, new research has shown. Researchers from Imperial College London, the Institute of Cancer Research (ICR) and the Netherlands Cancer Institute , found that the test can predict whether a bowel cancer patient will benefit from chemotherapy.

Researchers from the University of Sheffield's Institute of Translational Neuroscience have discovered how to prevent the death of nerve cells and protect nerves from neurodegeneration in the most common genetic forms of MND and frontotemporal dementia The researchers used a peptide, a small assembly of amino acids or protein bricks, with a cell-penetrating module to stop mutant repeated RNA molecules being transported from the cell's nucleus to
Edible electronics: how a seaweed second skin could transform health and fitness sensor tech
Scientists at the University of Sussex have successfully trialed new biodegradable health sensors that could change the way we experience personal healthcare and fitness monitoring technology. The team at Sussex have developed the new health sensors - such as those worn by runners or patients to monitor heart rate and temperature - using natural elements like rock salt, water and seaweed, combined with graphene.

Centuries after the first golden coffins were taken to Europe, ancient Egyptian mummies still vividly capture people's imaginations. Perhaps we're awed by the grandeur of their rituals and tradition. But new discoveries keep challenging scientists' perception of these ancient rites. As a biomedical Egyptologist, I study mummies to learn about life in ancient populations.
New perspective on processes behind Earth system change
The incoming head of the School of Geographical and Earth Sciences has contributed a Perspective article to the latest edition of the journal Science . Professor Todd Ehlers, currently of the University of Tübingen, Germany, was invited to contribute the piece in response to research published in the same issue which discusses a new computer-model reconstruction of global topography over the last 100 million years.

Mathematical research brings new understanding of crowd formation and behaviour. Have you ever wondered how pedestrians -know- to fall into lanes when they are moving through a crowd, without the matter being discussed or even given conscious thought? A new theory developed by mathematicians at the University of Bath led by Professor Tim Rogers explains this phenomenon, and is able to predict when lanes will be curved as well as straight.
Cat breeds at highest risk of kidney stones
Researchers from the Royal Veterinary College (RVC) have found the breeds that place cats at a higher risk of developing kidney and ureter stones, namely Burmese, Persian, Ragdoll and Tonkinese breeds. The research is the first of its kind to examine all cats with upper urinary tract uroliths (stones) as one group and hopes to support vets with diagnostic and treatment plans.

Women’s health at risk from reluctance to prescribe medicine during pregnancy
Research has found that a reluctance among healthcare professionals to prescribe and dispense medications to women who are pregnant is placing their health at risk. The study conducted by researchers at the British Pregnancy Advisory Service, Cardiff University, Pregnancy Sickness Support, and University College London, found that while prescribers need to balance maternal benefit with potential foetal harm when prescribing in pregnancy, women's individual circumstances were not always considered, and they were not fully engaged in decision making.

Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
NHS programme linked to 20% reduction in risk of Diabetes

Social media posts around solar geoengineering ’spill over’ into conspiracy theories
Researchers from the University of Cambridge have analysed more than 800,000 tweets and found that negative emotions expressed about geoengineering - the idea that the climate can be altered using technology - can easily fall into conspiracy. The researchers analysed tweets 2009 and 2021 tagged with #geoengineering.

Loneliness is central to perinatal depression
Loneliness can often contribute to depression in expectant and new mothers, finds a new review of evidence led by UCL researchers. The researchers say people working with expectant mothers, such as in antenatal classes or consultations, should be aware of the importance of loneliness and the value of encouraging new mothers to develop and maintain good social connections.

The cat’s out the bag: the most common diseases in pet cats revealed
Gum and dental disease, obesity, overgrown nails and flea infestation reported by the RVC as the top disorders in cats, with risks varying by age and sex. New research from the Royal Veterinary College (RVC) reveals the most common disorders diagnosed by veterinary surgeons across more than one million pet cats in the UK include gum disease, obesity, overgrown nails, and flea infestation.

Rare diseases are varied and life-threatening, yet most still remain undiagnosed and have no effective treatments. Now, scientists at the UCL Neurogenetics Lab are focusing on these conditions, to find diagnoses and treatments that could be crucial for scientific discovery. There is a common misconception that rare diseases only affect a small number of people.
An earlier first birth, a higher number of live births, and starting periods at a younger age may be linked to higher risk of cardiovascular problems. A new study, led by Imperial College London researchers, provides evidence for a causal relationship between sex-specific factors and cardiovascular disease in women, and identifies potential ways to mediate this increased risk.
Three years into a five-year pledge to completely phase out lead shot in UK game hunting, a Cambridge study finds that 94% of pheasants on sale for human consumption were killed using lead. If UK game hunters are going to phase out lead shot voluntarily, they are not doing very well so far Rhys Green The pledge, made in 2020 by nine major UK game shooting and rural organisations, aims to protect the natural environment and ensure a safer supply of game meat for consumers.
