Pill testing won’t give people a ‘green light’ to use drugs

New research from Edith Cowan University (ECU) has found pill-testing services at Western Australian music festivals would not change people’s intention to take ecstasy if they had not used the drug before, a common argument used by opponents of pill testing. The study also found people who planned to take ecstasy at the festival reported they would not consume more […]

3D lab skin for chemicals testing, research and repair

A model system that recreates full-thickness human skin should allow more effective testing of pharmaceuticals and cosmetics, while avoiding the need for animal tests. The system effectively models the development, cellular structure and barrier properties of skin. This should also make it suitable for analyzing disease states and wound repair processes. Another potential use is as a substrate for repairing […]

Rapid antigen testing for COVID-19: Piecing the puzzle together

A new study from Boston Children’s Hospital and the Massachusetts Department of Health compared one of the latest rapid antigen tests for COVID-19—the Abbott BinaxNOW—with a highly accurate PCR test in a high-volume, drive-thru testing environment. They found that the rapid test detected almost all adults who tested positive by PCR if they had had symptoms lasting seven days or […]

MicroRNA testing of healthy kids could provide a window on future heart and kidney health

Molecules called microRNAs (miRNAs) that are measurable in urine have been identified by researchers at Mount Sinai as predictors of both heart and kidney health in children without disease. The epidemiological study of Mexican children was published in February in the journal Epigenomics. “For the first time, we measured in healthy children the associations between urinary miRNAs and cardiorenal outcomes, […]

Chip simplifies COVID-19 testing, delivers results on a phone

COVID-19 can be diagnosed in 55 minutes or less with the help of programmed magnetic nanobeads and a diagnostic tool that plugs into an off-the-shelf cell phone, according to Rice University engineers. The Rice lab of mechanical engineer Peter Lillehoj has developed a stamp-sized microfluidic chip that measures the concentration of SARS-CoV-2 nucleocapsid (N) protein in blood serum from a […]

Novel pooled testing strategies can significantly better identify COVID-19 infections

A new approach to pooled COVID-19 testing can be a highly effective tool for curbing the SARS-CoV-2 pandemic, even if infections are widespread in a community, according to researchers at Harvard T.H. Chan School of Public Health and the Broad Institute of MIT and Harvard. Simple pooled testing schemes could be implemented with minimal changes to current testing infrastructures in […]

Even though mass testing for COVID isn’t always accurate, it could still be useful

The mass testing of asymptomatic people for COVID-19 in the UK was thrown into question by a recent study. In a pilot in Liverpool, over half the cases weren’t picked up, leading some to question whether using tests that perform poorly is the best use of resources. The tests involved in this study were antigen tests. These see whether someone […]

Will the US ever have a national COVID-19 testing strategy?

As the coronavirus epidemic worsens, U.S. health experts hope Joe Biden’s administration will put in place something Donald Trump’s has not—a comprehensive national testing strategy. Such a strategy, they say, could systematically check more people for infections and spot surges before they take off. The health experts say it would be an improvement from the current practice, which has professional […]

Winter coughs and fevers will put huge strain on COVID-19 testing capacity

Higher numbers of people with coughs and fevers in the coming months will place a significant strain on the UK’s COVID-19 testing system and capacity must be immediately scaled up, finds a new modeling study led by UCL and Liverpool School of Tropical Medicine. The study, currently published by Wellcome Open, quantified baseline cough or fever cases in the UK […]
