Scientists develop diagnostic test that can detect the virus that causes COVID-19 even when it mutates

A team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) has developed a diagnostic test that can detect the virus that causes COVID-19 even after it has gone through mutations. Called the VaNGuard (Variant Nucleotide Guard) test, it makes use of a gene-editing tool known as CRISPR, which is used widely in scientific research to alter DNA sequences […]

Scientists discover how COVID-19 virus causes multiple organ failure in mice

UCLA researchers are the first to create a version of COVID-19 in mice that shows how the disease damages organs other than the lungs. Using their model, the scientists discovered that the SARS-CoV-2 virus can shut down energy production in cells of the heart, kidneys, spleen and other organs. “This mouse model is a really powerful tool for studying SARS-CoV-2 […]

Age not just a number: Causes of joint stiffness differ between older and younger adults

Our lives and our bodies are dynamic. The physical state of someone in their twenties is probably vastly different from that of someone in their fifties. Naturally, healthcare should also be oriented differently to different age groups. Older people are more likely to fall and hurt themselves because their joints are less flexible than younger people. To minimize these risks […]

How rotavirus causes severe gastrointestinal disease

Rotavirus is a major cause of diarrhea and vomiting, especially in children, that results in approximately 128,000 deaths annually. The virus triggers the disease by infecting enterocyte cells in the small intestine, but only a fraction of the susceptible cells has the virus. In the mid-90s, scientists proposed that the small portion of infected cells promotes severe disease by sending […]

Nut consumption causes changes in sperm DNA function, study shows

Many environmental and lifestyle factors have been implicated in the decline of sperm quality, with diet being one of the most plausible factors identified in recent years. Moreover, several studies have reported a close association between the alteration of specific sperm DNA methylation signatures and semen quality. To date, however, no randomized clinical trials (RCT) have been published that assess […]

COVID-19 causes some patients’ immune systems to attack their own bodies, which may contribute to severe illness

Around the world, immunologists who retooled their labs to join the fight against SARS-CoV-2 are furiously trying to explain why some people get so sick while others recover unscathed. The pace is dizzying, but some clear trends have emerged. One area of focus has been the production of antibodies—powerful proteins capable of disabling and killing invading pathogens like viruses. Of […]

COVID-19 personal protective equipment causes serious skin injuries

A new study of medical staff treating COVID-19-infected patients found 42.8% experienced serious skin injury related to the use of personal protective equipment (PPE), including masks, goggles, face shields, and protective gowns. Researchers concluded that the skin injuries put staff at increased risk of infection, with insufficient prevention and treatment measures in place, according to the study published in Advances […]
