Animal Models in Space Research

On Wednesday, December 5th, the Falcon 9 SpaceX rocket launched to the International Space Station (ISS) carrying 5,600 lbs of supplies; a small portion of which were mice of varying ages2. Animal models have been used in space research since the 1940s, and these ongoing projects help us understand how spaceflight affects health in greater depth. This review will highlight the various animal models that have been...

Effective Communication Improves Quality

Let's listen in on a hypothetical conversation between a scientist and their procurement department where communication is being used ineffectively: PROCUREMENT OFFICER seated at desk. Enter a SCIENTIST. SCIENTIST: Order me twenty-four B6 mice. Males and Females. Seven weeks of age. PROCUREMENT: (Thinking to themselves) Same scientist, same number of mice from three months ago, I can just replicate the order. (To Scientist) OK. When do you...

How Are Animal Models Validated?

Animal models have led to significant leaps in understanding and advancement in human medicine. They are essential for drug discovery and connecting hypothesis-driven benchwork to the patient. However, scientists have struggled with how to define the value of a given animal model1. Animal Model Validation In 1969, McKinney and Bunney were the first to propose criteria on external validity of animal models, mainly focused on affective disorders2....

'Twas the End of the Year

With apologies to Clement C. Moore 'Twas the end of the year, and in laboratories throughout Scientists were working, to get that last paper out; The final experiments were designed with true care, In the hopes of results and citations so rare. The protocols were written and IACUC form submitted, All resources accounted for, tagged and committed. The technicians in lab coats and experiments underway, Seemed to...

A Deep Dive into AI-based Animal Body Part Detection

Photo courtesy of Dr. Alexander Mathis Animal behavior can provide valuable scientific insight, from assessing model validity of a disease state to understanding the function of complex neural circuits6,12. Accurately tracking an animal's body parts (such as limbs, digits, ears, snout, tail) is especially relevant within the neurodegenerative field11, but is difficult without highly specialized and demanding equipment. Many of the commercial systems and open source software...

Sex Bias in Animal Model Research

The National Institutes of Health (NIH) announced new policies in 2014 aimed at requiring NIH-funded researchers to address sex balance in preclinical cell and rodent models. Although exclusion of women in clinical research was identified as problematic decades ago, the preclinical research world has not followed suit. The NIH identified this continued reliance of animal studies on a single sex, often male, as inappropriate: "consideration of sex...

Rodent Sentinels — A Vital Link in Your Research

Rodent health monitoring programs (also referred to as rodent health surveillance or sentinel monitoring programs) are designed to detect subclinical infections of rodents that potentially have detrimental effects to the health of the animals or the integrity of your research. Robust sentinel animal protocols are both ethically and scientifically crucial. Sentinel Animal Protocols A health monitoring program is designed to detect infections that may be present within...

Smartphones Can Contaminate Laboratory Animal Colonies

As people increasingly rely on smartphones and tablets, it should come as no surprise that this trend also exists in laboratories. While this is unlikely to pose a problem in your kitchen when using your phone as a cooking timer, there are potential issues associated with use of smartphones and tablets in laboratory animal facilities. Such devices can be contaminated with bacteria, including pathogenic species which some...
