Microscopic, single cell differences found in the lungs of COVID-19 patients in Malawi demonstrate the value and importance of cutting-edge infectious disease research in Sub-Saharan Africa. The new study - the first of its kind in a Sub-Saharan population - is published in Nature Medicine and reveals previously unobserved differences in the inflammatory response to SARS-CoV-2, the virus that causes COVID-19, in patients who live in Malawi, compared to those who live in western countries.

Scientists from NASA and our Department of Physics have used supercomputer simulations to reveal that Mars' moons may have been formed from destroyed asteroid fragments. The researchers found that an asteroid passing near Mars could have been pulled apart by the planet's gravity, with the resulting rock fragments strewn into a range of orbits.

An elusive particle that first formed in the hot, dense early universe has puzzled physicists for decades. Following its discovery in 2003, scientists began observing a slew of other strange objects tied to the millionths of a second after the Big Bang. Appearing as 'bumps' in the data from high-energy experiments, these signals came to be known as short-lived 'XYZ states.' They defy the standard picture of particle behaviour and are a problem in contemporary physics, sparking several attempts to understand their mysterious nature.

Police services across Britain are failing to meet the public's minimum standards of service delivery, according to a new report from researchers at UCL and the ESRC Vulnerability & Policing Futures Research Centre, which measures this sentiment for the first time. For the report , the research team sought the views of members of the public across Britain to establish the minimum standards of service that the public should be able to expect from the police.

Fighting bowel cancer with the bacteria Salmonella could be a step closer thanks to a new discovery by researchers at the University of Glasgow and the University of Birmingham. The new study, funded by Cancer Research UK and published today in the journal EMBO Molecular Medicine, studied the response of T cells to a specially engineered safe form of Salmonella in mice with colorectal cancer.

Our researchers have studied wild monkeys problem-solving for food to better understand how social dynamics can influence behaviour and learning. The research team, led by our Department of Anthropology, and in collaboration with University of São Paulo, studied two groups of wild bearded capuchin monkeys in Brazil's Serra da Capivara National Park.

People with a high mammographic density (HMD) are more likely to develop breast cancer. Dr Isobel Taylor-Hearn is investigating why. Breast cancer is the leading cause of death in UK women aged between 35 and 49. Routine breast screening doesn't start until women are 50. Overall, around 12% of the female population will get breast cancer at some point during their lifetime.

Some of the first human beings to arrive in Tasmania, over 41,000 years ago, used fire to shape and manage the landscape, about 2,000 years earlier than previously thought. A team of researchers from the UK and Australia analysed charcoal and pollen contained in ancient mud to determine how Aboriginal Tasmanians shaped their surroundings.

Uranus's upper atmosphere has been cooling for decades - and now scientists have shown why. Observations from Earth have shown Uranus' upper atmosphere has been cooling for decades, with no clear explanation. Now, a team led by Imperial College London scientists has determined that unpredictable long-term changes in the solar wind - the stream of particles and energy coming from the Sun - are behind the drop.

Working days lost to long Covid could be costing the economy billions of pounds every year as patients struggle to cope with symptoms and return to work, finds a new study led by UCL researchers. The research, published in BMJ Open and funded by the National Institute for Health and Care Research (NIHR), examined the impact of long Covid on 4,087 patients who were referred to a long Covid clinic and registered in the Living With Covid Recovery (LWCR) programme between August 2020 and August 2022.

Two conflicting memories can both be activated in a worm's brain, even if only one memory actively drives the animal's behaviour, finds a new study by UCL researchers. In the paper published in Current Biology , the researchers showed how an animal's sex drive can at times outweigh the need to eat when determining behaviour, as they investigated what happens when a worm smells an odour that has been linked to both good experiences (mating) and bad experiences (starvation).

The ageing and failure of cells that occurs when the liver is damaged can spread to other organs, suggests a new study in mice and humans from researchers at UCL, the University of Edinburgh and the CRUK Scotland Institute. In the study, published in Nature Cell Biology , scientists demonstrate for the first time that the deterioration of cells in a damaged liver can activate a process associated with ageing and impaired function, which then transmits to otherwise healthy organs elsewhere in the body.

Scientists say the findings might shed light on the link between loneliness and mental health conditions such as anxiety disorders, which are on the rise in young people. People in their late teens experience an increased sensitivity to threats after just a few hours left in a room on their own - an effect that endures even if they are interacting online with friends and family.

An international team that includes the University of Bath has discovered three ultra-massive galaxies in the early Universe forming at unexpected speeds. An international team that was led by the University of Geneva (UNIGE) and includes Professor Stijn Wuyts from the University of Bath has identified three ultra-massive galaxies - each nearly as massive as the Milky Way - that had already assembled within the first billion years after the Big Bang.

New Study Reveals Financial Ombudsman Service is inflating complaint success rates New research has shown that the Financial Ombudsman Service (FOS) is inflating the rate that it reports complaints to it as successful. Academics from The University of Warwick have analysed judgements by the Ombudsman and found that many cases were recorded as successful, even when the complaint was essentially rejected and either no additional compensation or tokenistic compensation was awarded.

Mysteries about Uranus that have baffled scientists for decades may have been the result of an unusually powerful solar storm that happened to occur as a spacecraft visited the planet, a new study involving UCL researchers has found. NASA's Voyager 2, which flew by Uranus in 1986, provided scientists' first, and so far only, close glimpse of the planet, shaping their understanding of it in the decades since.

The most comprehensive study ever conducted of lung cancer diagnosis in England has revealed significant disparities between ethnic groups and striking evidence that people living in the most deprived areas were diagnosed with lung cancer at twice the rate of those in affluent areas.

An international team of researchers, including Dr Peter Etchells from our Department of Biosciences, have published new research which brings to light new discoveries in the development and understanding of stem cells. The new study, published by the journal Science, saw researchers from Durham, University of Helsinki and Utrecht University collaborate to identify the key components required to control the balance of stem cells in plants.

Neuroscientists at UCL have discovered brain cells that form multiple coordinate systems to tell us "where we are" in a sequence of behaviours, in a new study in mice. These cells can play out different sequences of actions, just like a music box can be configured to play different sequences of tones.

A new advance in health monitoring which uses radar to 'listen' to patients' heart sounds with remarkable accuracy could lead to a new generation of contactless medical monitoring equipment. Researchers from the University of Glasgow led the development of the new system, which uses radar to track patients' heart sounds like a doctor uses a stethoscope.
