Most London pavements are not wide enough for social distancing
Two thirds of pavements in London are not wide enough for people to observe the government's advice to stay two metres apart, according to new UCL analysis. Looking at data for every street in Greater London, the researchers found that only 36% had pavements that were at least three metres wide - judged to be the minimum required for people to be able to keep their distance.

Largest amount of microplastics found on ocean floor
Largest amount of microplastics found on ocean floor
Our researchers have helped record the highest level of microplastics ever found on the ocean floor - with up to 1.9 million pieces in an area of just one square metre. The discovery highlights the problem of plastic pollution in our seas, 99 per cent of which lies beneath the waves. Working as part of an international team the researchers have shown how deep-sea currents act as conveyor belts, transporting tiny plastic fragments and fibres across the seafloor.

Opinion: Until we have a vaccine for coronavirus, treatments like remdesivir are our only hope
Dr Jennifer Rohn (UCL Medicine) explains that conflicting evidence from early trials is the norm in science, and we must be patient as the data unfolds. Drug discovery and testing, even under normal circumstances, is a high-risk process full of red herrings and dashed hopes. In the throes of a global pandemic, the stakes are even higher and the risks remain the same.

Don’t ignore vague symptoms of cancer during pandemic, urge researchers
People need to be alert to the more vague symptoms of cancer and not be afraid to seek advice from their GPs during the global coronavirus pandemic, medical researchers say. They also warn new ways of remote working could make it harder for GPs to pick up on worrying symptoms, in a comment article published today in Lancet Oncology.

Covid-19 effects in the elderly tracked in ongoing study
To better understand the impact of Covid-19 on the elderly, and to find out why the virus disproportionality affects this age group, LINKAGE has developed the 'Covid-19 sub-study'. Lead researcher Dr Daniel Davis (UCL Population Science & Experimental Medicine), said: "The original design of the LINKAGE study has meant we are in the perfect position to follow participants at all stages of infection: from being well, into early infection and throughout the course of the illness.

Being male or overweight can lead to more serious COVID-19 hospital admissions
New UK research has found that being male or obese reduces chance of survival from severe coronavirus disease (COVID-19). The findings come from a study of almost 17,000 patients with COVID-19, in which researchers from three universities, including Imperial, aim to answer important questions about the course of and risk factors for the disease.

Simple ’sniff test’ reliably predicts recovery of severely brain injured patients
The ability to detect smells predicts recovery and long-term survival in patients who have suffered severe brain injury, a new study has found. A simple, inexpensive 'sniff test' could help doctors to accurately diagnose and determine treatment plans for patients with disorders of consciousness. The accuracy of the sniff test is remarkable - I hope it will help in the treatment of severely brain injured patients around the world.

Economic damage could be worse without lockdown and social distancing - study
Economic damage could be worse without lockdown and social distancing - study
The worst thing for the economy would be not acting at all to prevent disease spread, followed by too short a lockdown, according to research based on US data. Taking no action is unacceptable from public health perspective, and extremely risky from an economic perspective Giancarlo Corsetti There is much debate over the economic costs of our lockdown lives: whether the price of disease mitigation is worth the risk of an enduring financial crisis.

Artificial intelligence still lags behind humans at recognising emotions
When it comes to reading emotions on people's faces, artificial intelligence still lags behind human observers, according to a new study involving UCL. The difference was particularly pronounced when it came to spontaneous displays of emotion, according to the findings published in PLOS One. The research team, led by Dublin City University, looked at eight "out of the box" automatic classifiers for facial affect recognition (artificial intelligence that can identify human emotions on faces) and compared their emotion recognition performance to that of human observers.

New drug formulation could treat Candida infections
New drug formulation could treat Candida infections
Candida albicans , a well-known yeast usually seen in the mouth, skin, gut and vagina, is reported to form biofilms and cause mild to life threatening infections. Fluconazole, an antifungal drug widely used to treat Candida infections is completely ineffective in treating Candida biofilms and new drugs are needed to treat them.

Long-term use of synthetic corticosteroid drugs increases adrenal gland inflammation
Synthetic corticosteroid drugs are widely prescribed to treat many inflammatory and autoimmune diseases but taking a high dose over a long period of time can cause adverse side effects. Patients undergoing prolonged corticosteroid treatment can also develop adrenal insufficiency, which in rare occasions can lead to adrenal gland failure.

Weekly COVID-19 testing in healthcare and care home staff may reduce spread
A new report looks at how different testing strategies could help control COVID-19. The World Health Organisation has called for increased molecular testing in response to the COVID-19 pandemic but different countries have taken very different approaches. “We find that testing is most useful when targeted at high-risk groups such as healthcare and care home staff.” Professor Nicholas Grassly Study author The new report investigates how effective alternative strategies could be for COVID-19 control, using a mathematical model.

Patterns of common coronavirus infections could aid understanding of COVID-19
Coronavirus infections are a common cause of mild colds, infecting thousands of people every year in the UK. They mostly circulate in the winter in temperate regions where they are often referred to as 'seasonal coronaviruses'. However, in contrast to many other infectious diseases, not much is known about how often, and in whom, these viruses cause illnesses requiring medical attention.
