Iflscience mouse utopia8/24/2023 You never know where the next pandemic will come from. "That's why it's important to fund vaccine research. We knew exactly where to fight this new virus," said co-senior author Andrea Gambotto, MD, associate professor of surgery, in a statement. "These two viruses, which are closely related to SARS-CoV-2, teach us that a particular protein, called a spike protein, is important for inducing immunity against the virus. Researchers at the University of Pittsburgh School of Medicine were able to move quickly because they had laid the groundwork for a vaccine during earlier coronavirus epidemics, like the Severe Acute Respiratory Syndrome ( SARS) outbreak in 2003 and the Middle East Respiratory Syndrome ( MERS) epidemic nine years later. The vaccination was created four weeks after scientists were able to successfully sequence SARS-CoV-2. Aberrations included the following: females abandoning their young males no longer defending their territory and both sexes becoming more violent and aggressive. "And it's actually pretty painless – it feels kind of like Velcro.” The researchers use FDA Good Manufacturing Practice to produce vaccines suitable for human clinical trials. The turning point in this mouse utopia, Calhoun observed, occurred on Day 315 when the first signs appeared of a breakdown in social norms and structure. - A hidden gem published on YouTube shows the inside of the infamous Universe 25 experiment, which saw a mouse utopia turn into a mouse apocalypse. “We developed this to build on the original scratch method used to deliver the smallpox vaccine to the skin, but as a high-tech version that is more efficient and reproducible patient to patient," said co-senior author Louis Falo, MD, PhD, professor and chair of dermatology at Pitt's School of Medicine and UPMC in a statement. Each needle is made of sugar and protein pieces that dissolve into the skin. By day 600, the mice lost all social skills required to mate. Despite appearances, these maladaptive mice could not cope with the stresses of life. They devoted their time solely to grooming, eating, and sleeping, becoming known as the beautiful ones. A finger-tip sized patch with 400 tiny needles is applied directly to the skin – which is where immune reaction is the strongest – and goes on like a Band-Aid. In the final stages of mouse utopia, some young male mice never engaged in sex or fighting. It is delivered using a microneedle array to increase potency.
