Up in smoke: Smoking increases SARS-CoV-2 receptors in the lung

New research suggests that cigarette smoke spurs the lungs to make more ACE2 (angiotensin-converting enzyme 2), the protein that the coronavirus responsible for COVID-19 grabs and uses to enter human cells. The findings, reported in the journal Developmental Cell, may explain why smokers appear to be particularly vulnerable to severe infections. The analysis also indicates that the change is…

A new way to detect blood clots

Biomedical engineering researchers at Texas A&M University designed a medical device that mimics blood vessels to design and monitor drugs for patients with clotting disorders. This approach could be especially beneficial for pediatric patients. Unlike what a biology textbook may show, blood vessels are not straight cylinders. They are tortuous, meaning they have complex curves, spirals and…

AI enhances brain tumour diagnosis

A new machine learning approach classifies a common type of brain tumour into low or high grades with almost 98% accuracy, researchers report in the journal IEEE Access. Scientists in India and Japan, including from Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS), developed the method to help clinicians choose the most effective treatment strategy for individual…

Researchers find 'resistance resistant' antibiotic

University of Melbourne researchers are finding ways to beat dangerous superbugs with ‘resistance resistant’ antibiotics, and it could help in the fight against coronavirus (COVID-19) complications. As bacteria evolve, they develop strategies that undermine antibiotics and morph into ‘superbugs’ that can resist most available treatments and cause potentially lethal infections. The…

Experts explore COVID-19 airborne transmission

Preventing airborne transmission of COVID-19 should be the next front of the battle against the virus, argue experts from the University of Surrey. In a study published by the City and Environment Interaction journal, scientists from Surrey’s Global Centre for Clean Air Research (GCARE), together with partners from Australia’s Queensland University and Technology, argue that the lack of…

COVID-19 study reveals universally effective antibodies

The first round of results from an immunological study of 149 people who have recovered from COVID-19 show that although the amount of antibodies they generated varies widely, most individuals had generated at least some that were intrinsically capable of neutralizing the SARS-CoV-2 virus. Antibodies vary widely in their efficacy. While many may latch on to the virus, only some are truly…

Cruise ship study hints at many ‘silent’ COVID-19 infections

The prevalence of ‘silent’ symptomless COVID-19 infection may be much higher than thought, reveals a study charting the enforced isolation of cruise ship passengers during the current pandemic, and published online in the journal Thorax. More than eight out of 10 of passengers and crew who tested positive for the infection had no symptoms. This has implications for the easing of lockdown…

Is pain research turning a blind eye on women?

Females process pain differently, but search for pain medication still based on hypotheses drawn from work in males, a study from Canada finds. It is increasingly clear that male and female humans and rodents process pain in different ways. And that there are important differences in the underlying mechanisms involved at genetic, molecular, cellular, and physiological levels. Despite this fact,…

Risk factors for severe and fatal COVID-19 cases identified

Age, male sex, obesity, and underlying illness have emerged as risk factors for severe and fatal cases of COVID-19 in the UK, according to the largest cohort study to date published by The BMJ. As the largest prospective observational study reported worldwide to date, it provides a comprehensive picture of the characteristics of patients hospitalised in the UK with COVID-19 and their outcomes.…

Micro robot rolls deep into the body

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell travelling through the circulatory system. It has the shape, the size and the moving capabilities of leukocytes and could perhaps be well on its way – in a rolling motion of course – to revolutionize the minimally invasive treatment of…

Measuring blood damage in real-time

Scientists at the University of Delaware and Princeton University have developed a method to monitor blood damage in real-time. “Our goal was to find a method that could detect red blood cell damage without the need for lab sample testing,” said Tyler Van Buren, an assistant professor of mechanical engineering with expertise in fluid dynamics. The researchers recently reported their technique…

Inside COVID-19's 'cytokine storm'

Leading immunologists in Japan are proposing a possible molecular mechanism that causes massive release of proinflammatory cytokines, or a cytokine storm, leading to the acute respiratory distress syndrome (ARDS) in COVID-19 patients. Their suggestions, published in the journal Immunity, are based on recent findings that explain how SARS-CoV-2 enters human cells.

Understanding immunity to SARS-CoV-2

Why does every person react differently to an infection with the coronavirus SARS-CoV-2? Why do some people have no symptoms or only mild symptoms of COVID-19, the disease which it causes?
