A new study in Australia has shown that shoppers making simple food and drink switches could reduce greenhouse gas emissions from groceries by 26%. Researchers from The George Institute for Global Health and Imperial College London's School of Public Health conducted the most detailed analysis ever on the environmental impacts of a country's food buying behaviour.

Research suggests that plastic pollution must be reduced by at least 5% every year to make progress towards UN targets by the end of the century. The study, a collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics - plastics less than 5 mm in length - in the surface oceans.

The brain's ability to rid itself of toxins may actually be reduced during sleep, contrary to the leading scientific theory. Over the past decade, the leading explanation for why we sleep has been that it provides the brain with an opportunity to flush out toxins. However, a new study led by scientists at the UK Dementia Research Institute (UK DRI) at Imperial College London indicates that this may not be true.

New analysis has revealed more about the origins of the main bacterial strain involved in an increase in lethal cases. Strep A (Group A Streptococcus) is a common type of bacteria that typically causes throat infections and scarlet fever. While most infections are mild, in rare cases Strep A can cause invasive infections which can be fatal.

A new imaging technique tested on patients could improve the evaluation of cardiac conditions and undiagnosed chest pain. Researchers from Imperial College London's Department of Bioengineering and Faculty of Medicine worked alongside academics from UCL to produce sub-millimetre resolution images of cardiac micro-vessels.

A study shows that if communities think outsiders are stealing their forest resources, they are more likely to want to increase their own harvest. The research, led by Imperial College London and Max Plank Institute of Evolutionary Anthropology researchers, shows why effective boundaries around a community's common-pool resource are key to sustainable management of that resource.

Mexico is leading the way in implementing taxes on unhealthy food options, successfully helping to tackle obesity and related health issues. Taxes on foods that are high in fat, salt or sugar (HFSS) reduce the sale, purchase and consumption of those foods, according to a new peer-reviewed analysis of evidence from around the world from Imperial College Business School.

A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health. The study, published today in Microbiome , looked at coral reefs specifically, but the researchers say it could be widely applicable as a method for measuring how ecosystems are responding to human activities.

People with long COVID have distinct patterns of inflammation detectable in the blood, which could potentially be targeted with immune therapies. Findings from the largest UK study of patients hospitalised with SARS-CoV-2 infection show that long COVID leads to ongoing inflammation which can be detected in the blood.

Researchers have uncovered why people are more likely to have heart arrhythmia first thing in the morning. Many studies have shown that potentially lethal heart rhythm disturbances ('ventricular arrhythmia') are more likely to occur in the morning, when people wake after a night's sleep, but until now the trigger mechanism has not been fully understood.

Researchers at Imperial College London have genetically engineered bacteria to grow animaland plastic-free leather that dyes itself. In recent years, scientists and companies have started using microbes to grow sustainable textiles or to make dyes for industry - but this is the first time bacteria have been engineered to produce a material and its own pigment simultaneously.

Researchers have developed a new platform for the synthesis, analysis and testing of new compounds which may one day treat cancer The discovery of new compounds with pharmacological properties can be expensive and time-consuming. Therefore, there is an increasing interest in developing workflows that allow for the rapid synthesis and testing of multiple compounds in parallel.

The first national study of surgical video across the NHS has revealed that policies and procedures vary significantly. Recording surgical procedures can provide an invaluable tool to train clinical staff, but the policies in place around video recording for training vary hugely from one hospital to the next, a study has found.

Imperial College London and NASA researchers have found signs that water was plentiful in Mars' Gale crater for longer than previously thought. Billions of years ago, Mars was home to abundant water, and its Gale crater contained a lake. Gradually, the climate changed, drying the Red Planet and creating the dusty desert world we know today.

Research undertaken in Fiji found that communities were more likely to adopt marine conservation initiatives if their neighbours have. A new paper published in Global Environmental Change featuring Imperial College London researchers explores how Indigenous-led initiatives can be scaled to protect marine ecosystems.

Using a mobile phone for extended periods is not linked with an increased risk of brain cancer, a study shows. These are the findings from the COSMOS study, a large international project led by researchers at the Karolinska Institutet in Sweden and Imperial College London. Starting in 2007, researchers studied more than 250,000 mobile phone users to investigate if extensive use of mobile phones increases the risk of brain tumours over time.

Researchers have carried out the largest study to date on the potential health impacts from airborne dust on the London Underground. The research, led by Imperial College London, found that staff who worked in areas with higher levels of fine dust - called particulate matter (PM 2.5 ) - also tended to report more episodes of sickness absence.

A new Imperial College London study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest. There's a discrepancy in the animal kingdom. While many key traits such as strength, limb length, lifespan and brain size tend to increase with animals' size, maximum running speeds tend to be greatest in medium-sized animals.

Search engine data could be used to detect gynaecological cancer cases earlier, potentially months ahead of GP referrals, according to new research. A study, led by researchers and colleagues from UCL's Department of Computer Science and Microsoft, has identified differences in online search data between people with a benign gynaecological condition and those with a gynaecological cancer, particularly those with ovarian cancer.

A UK trial has found a DNA-tailored diet could help manage blood glucose and reduce risk of progressing to type 2 diabetes in high-risk individuals. The findings come from a small Imperial College London and DnaNudge pilot study involving 148 people with high blood sugar levels who were at risk of going on to develop type 2 diabetes (T2D).
