Upper limit for the speed of sound
Upper limit for the speed of sound
A research collaboration between the University of Cambridge, Queen Mary University of London and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound. The result - about 36 km per second - is around twice as fast as the speed of sound in diamond, the hardest known material in the world.

Scientists develop new ’Precision Medicine’ approach to treating damaged DNA in Pancreatic Cancer
Scientists have developed a new 'Precision Medicine' approach to treating the damaged DNA in the cancer cells of Pancreatic Cancer patients. The findings mark an important step forward for potential treatment options for pancreatic cancer, improving the options and outcomes for a disease where survival rates have remained stubbornly low.

UofG-led arthritis research centre creates new generation of scientists
A University of Glasgow-led national centre for research into inflammatory arthritis is proud to announce it has awarded 12 PhDs in its first round of funding, creating a new cadre of young scientists trained in pathogenesis research to fight arthritis. The Research into Inflammatory Arthritis Centre Versus Arthritis (RACE), who received renewed funding of nearly £2m over five years from Versus Arthritis last August, is now in its second phase and will be appointing a further 12 PhD students shortly - seven PhD students will start this year, with five more to start in 2021.

Mechanical forces of biofilms could play role in infections
Studying bacterial biofilms, EPFL scientists have discovered that mechanical forces within them are sufficient to deform the soft material they grow on, e.g. biological tissues, suggesting a -mechanical- mode of bacterial infection. The vast majority of bacteria in the world live on surfaces by forming structures called -biofilms-.

Way to improve multiple sclerosis treatment
Multiple sclerosis, an autoimmune disease of the central nervous system that affects millions worldwide, can cause debilitating symptoms for those who suffer from it. Though treatments exist, researchers are still searching for therapies that could more effectively treat the disease, or even prevent it altogether.

Four in 10 extra deaths in Lombardy not linked to Covid-19
About 24,000 more people died in Lombardy than expected between January and April, and only 14,000 of these deaths were confirmed as being related to Covid-19, according to a new study led by researchers at UCL and Imperial College London. The study, published in PLOS ONE , looked at the number of deaths in each of the 7,251 local authority areas of Italy during the first four months of the year and compared these figures with predictions based on data from 2016-2019.

HIV epidemic: Successful use of self-tests in rural Africa
HIV epidemic: Successful use of self-tests in rural Africa
Despite significant progress in prevention and therapy, millions of people still get infected with HIV every year. The main burden of HIV/AIDS falls on Africa. To contain the epidemic, innovative methods are needed to enable early diagnosis of all those affected. A Basel research group has now been able to significantly improve the success of "door-to-door" testing campaigns thanks to HIV self-tests.

It looks absolutely idyllic, watching the Heck cattle and Konik horses grazing in the meadows in the Emsaue wet meadows near the village of Vadrup. This pasture landscape, covering an area of 33 hectares and used all year round, lies in the Emsaue nature conservation area and was set up in 2004 as part of the implementation of the plan to protect the wet meadows by the River Ems.

When stuck in a rut, it may be time to try ideas from others
When stuck in a rut, it may be time to try ideas from others
When attempting to solve a problem, people often fall back on prior experiences that worked, sometimes without considering other solutions. In other words, they stay in their comfort zone, which psychologists call "fixation.” Researchers at the University of Michigan, University of Limerick and Iowa State University investigated what happens when new engineers attempt to design a solution on their own with no examples: They tend to stick to their original idea and not try other options.

Bacteria in sediment continue to show effects of over-fertilisation
Bacteria in sediment continue to show effects of over-fertilisation
Whether a lake was once polluted with excess nutrients is reflected even decades later in the community of bacteria living on these nutrients in the sediment. However, there is still surprisingly little research into how microbes in the sediment cooperate. From a global perspective, lake sediments are important carbon sinks.

Modeling eternity in the rock laboratory
Modeling eternity in the rock laboratory
Cement is one of the key materials for the safe storage of radioactive waste. What is needed is an almost infinite durability of the containers. Empa researchers are therefore analyzing material systems that can handle this task. Exploratory tunnel in the Mont Terri international rock laboratory. Since 1996, rock formations that could play a role in the storage of radioactive waste have been investigated here.

Clean Air Act reduced racial disparities in pollution
Air pollution has disproportionately hurt minority and low-income communities, leading to reduced life expectancy, research has found. Yet a lack of data has stymied efforts to quantify the problem-and its causes-nationwide. A recent study, anchored by new satellite-based measures of air quality, found some encouraging news: The gap between Black and white Americans' particulate exposure has declined over the past two decades, due largely to enforcement of the Clean Air Act in the country's most polluted areas.

New Class of Highly Effective Inhibitors Protects against Neurodegeneration
Heidelberg neurobiologists decode central mechanism of degenerative processes in the brains of mouse models and develop new principle for therapeutic agents Neurobiologists at Heidelberg University have discovered how a special receptor at neuronal junctions that normally activates a protective genetic programme can lead to nerve cell death when located outside synapses.

How SARS-CoV-2 Disables the Human Cellular Alarm System
How SARS-CoV-2 Disables the Human Cellular Alarm System
As the world is more than half a year into the COVID-19 pandemic, doctors and researchers have a fairly good idea of what the main symptoms of the disease look like: cough, fever, shortness of breath, and fatigue, among others. But equally important to treating symptoms is understanding what the coronavirus that causes COVID-19, SARS-CoV-2, is doing inside human cells to make people so sick.

Social factors are key to identifying heart disease risk
Asking people simple questions about their social situation in addition to medical measures will give a more accurate picture of who might have a heart attack in the future, finds a study led by UCL researchers. The study, published this week in the European Heart Journal , shows for the first time, that factors such as educational qualifications, employment, marital status, mental health, BMI and physical activity could be crucial in identifying who is most at risk of heart disease.

Athletes using sport supplements are more open to doping - study
Athletes using legal performance enhancing and medical sport supplements are more likely to dope than those using sport foods and superfoods, a new study reveals. While some sport supplements may be necessary for an athlete's programme, taking ergogenic and medical sport supplements may inadvertently lead to sports people developing favourable attitudes towards doping Researchers at the University of Birmingham and Canterbury Christ Church University are calling for bespoke anti-doping education for athletes using such supplements to prevent them turning to banned substances.

Miniature organs shed light on intestinal regeneration
In a study, researchers from Basel unraveled mechanisms orchestrating organoid formation and intestinal regeneration. Using a unique image-based screening approach, the researchers identified a compound that improves intestinal regeneration in mice. The last decade has seen a boom in the field of organoids, miniature organs grown from stem cells in vitro.
