Novel study of high-potency cannabis shows some memory effects

Even before the pandemic made Zoom ubiquitous, Washington State University researchers were using the video conferencing app to research a type of cannabis that is understudied: the kind people actually use. For the study, published in Scientific Reports, researchers observed cannabis users over Zoom as they smoked high-potency cannabis flower or vaped concentrates they purchased themselves from cannabis dispensaries in […]

Study reveals mechanisms of increased infectivity and antibody resistance of SARS-CoV-2 variants

Combining structural biology and computation, a Duke-led team of researchers has identified how multiple mutations on the SARS-CoV-2 spike protein independently create variants that are more transmissible and potentially resistant to antibodies. By acquiring mutations on the spike protein, one such variant gained the ability to leap from humans to minks and back to humans. Other variants—including Alpha, which first […]

New study finds SARS-CoV-2 can infect testes

Researchers at the University of Texas Medical Branch have observed that SARS-CoV-2, the virus that causes COVID-19, can infect the testes of infected hamsters. The findings, published in the journal Microorganisms, could help explain symptoms some men with COVID-19 have reported and have important implications for men’s health. As the pandemic goes on, clinicians continue to report their findings that […]

Study finds ‘serious problems with privacy’ in mobile health apps

An in-depth analysis of more than 20,000 health related mobile applications (mHealth apps) published by The BMJ today finds “serious problems with privacy and inconsistent privacy practices.” The researchers say the collection of personal user information is “a pervasive practice” and that patients “should be informed on the privacy practices of these apps and the associated privacy risks before installation […]

Study highlights need to monitor oxygen therapy in children with pneumonia

Oxygen therapy can save the lives of children with pneumonia, but careful monitoring is needed to reduce harm, avoid over-reliance and protect supply. These are among some of the key findings to emerge from a four-year-long study of children hospitalized with severe pneumonia in East Africa. Led by researchers at Imperial College London, the Children’s Oxygen Administration Strategies Trial (COAST) […]

Preclinical study suggests new approach to reduce COVID-19 death among the elderly

New research from the University of Minnesota Medical School and colleagues at the Mayo Clinic reveals a possible new approach to preventing death and severe disease in elderly people infected with SARS-CoV-2. The researchers demonstrated in a preclinical study that senolytic drugs significantly reduced mortality upon infection from a beta-coronavirus closely related to SARS-CoV-2 in older mice. The study published […]

Study shows BPA exposure below regulatory levels can impact brain development

Humans are exposed to a bath of chemicals every day. They are in the beds where we sleep, the cars that we drive and the kitchens we use to feed our families. With thousands of chemicals floating around in our environment, exposure to any number is practically unavoidable. Through the work of researchers like Dr. Deborah Kurrasch, Ph.D., the implications […]

Study reveals inequities in breast cancer screening during COVID-19 pandemic

Breast cancer screening took a sizeable hit during the COVID-19 pandemic, suggests new research that showed that the number of screening mammograms completed in a large group of women living in Washington State plummeted by nearly half. Published today in JAMA Network Open, the study found the steepest drop-offs among women of color and those living in rural communities. “Detecting […]

Study finds new and effective treatment for vitamin D deficiency

There are several million people worldwide with various fat malabsorption syndromes including those who have undergone gastric bypass surgery and those with obesity. These patients often have a difficult time absorbing vitamin D and both groups of patients are at an increased risk for vitamin D deficiency and therefore at higher risk for osteoporosis and osteomalacia (softening of the bones). […]
