UNIVERSITY PARK, Pa. — For more than 40 years, scientists have hypothesized the existence of enzyme clusters, or “metabolons,” in facilitating various processes within cells. Using a novel imaging technology combined with mass spectrometry, researchers at Penn State, for the first time, have directly observed functional metabolons involved in generating purines, the most abundant cellular...

There is no evidence that the coronavirus was created in a laboratory
by Eric Muraille, The Conversation The COVID-19 pandemic, which is disrupting our lives and shaking our health systems and economies, is at the root of what Dr. Sylvie Briand, director of the Department of Pandemic and Epidemic Diseases of the World Health Organization (WHO), rightly described as an infodemic– the viral circulation of rumours and...

Is Parkinson’s an autoimmune disease? More evidence emerges
Researchers in Germany have found further evidence to support the idea that Parkinson’s could be an autoimmune disease. Using a stem cell model, they showed how immune cells attacked dopamine-producing cells derived from people with Parkinson’s disease but not from people without it. Dopamine is a chemical messenger that supports many important brain functions. These include functions that deal with...

Cell Transplant Trial for Spinal Injury Is Safe
The first human experiment with neural precursor cells implanted to treat chronic spinal cord injury suggests the procedure is safe, and hints at a small benefit. Four patients with chronic spinal damage and a complete loss of motor and sensory functions below their waists have received transplants of human neural stem cells in a first-of-its-kind...
