A new study by researchers at Queen Mary University of London, University of Oxford, Institute for Advanced Studies, Vienna, and the Medical University of Graz, has found that lateral flow tests detect Covid-19 with similar accuracy to laboratory-based PCR tests, providing they are used at the onset of infection and soon after symptoms start.
Lateral flow tests are cheaper and produce a result in just 30 minutes - much faster than the time it takes to receive a PCR test result, which can take 1-3 days. The finding could be pivotal to national strategies looking to tackle the next phase of the pandemic, especially as timely and rapid testing becomes even more important once the current restrictions lift in England.

E-cigarettes are more effective than nicotine replacement treatments in achieving long term smoking reduction and cessation, according to the results of a clinical trial by Queen Mary University of London.
Some 80 per cent of smokers receiving intensive treatment continue to smoke after a year. Smokers could benefit from approaches that reduce the harm from smoking without ceasing nicotine use, with an option to stop nicotine later on. Nicotine replacement treatments (NRT), such as nicotine patches, chewing gum, nasal/mouth spray and inhalators, have been licenced to do this for over 30 years. They work, especially if behavioural support is also provided, but the results are modest.

People with healthier heart structure and function appear to have better cognitive abilities, including increased capacity to solve logic problems and faster reaction times, according to research led by Queen Mary University of London and the Radcliffe Department of Medicine at University of Oxford.
Dr Zahra Raisi-Estabragh, BHF Clinical Research Training Fellow at Queen Mary University of London said: Heart disease and dementia are important and growing public health problems, particularly in ageing populations. We already knew that patients with heart disease were more likely to have dementia, and vice versa, but we ve now shown that these links between heart and brain health are also present in healthy people. We demonstrated for the first time, in a very large group of healthy people, that individuals with healthier heart structure and function have better cognitive performance.
The remaining family of a missing Sydney model turned prostitute has welcomed a $1million reward for information about her disappearance 26 years ago.
Revelle Balmain, 22, was last seen on November 5, 1994, at Kingsford, in the city s eastern suburbs and is presumed to have been murdered.
Ms Balmain s half-sister, Suellen Simpson, said her sibling s disappearance had caused immeasurable grief to her family for a quarter of a century. For many years, our family worked tirelessly to find out what happened to my sister - but sadly both our mother and Revelle s father, Ivor, passed away without ever knowing what happened to their little girl, Ms Simpson said.
