For millions of years, proboscideans — a group that includes mammoths, mastodons, and elephants — traversed diverse landscapes, shaping ecosystems as they went. However, around 11,700 years ago, human hunting and the waning ice age drastically reduced their numbers to just three species — the Asian elephant, the African forest elephant, and the African savanna elephant, as stated by Iqbal from ScienceNews.org. These giants are now endangered, and the impact of losing them extends far beyond what meets the eye. The American Museum of Natural History in New York City has opened its doors to a fascinating exhibit that delves into the profound impact of these gentle giants on the environment and human culture. This immersive experience unveils the hidden wonders of elephants through cutting-edge science and captivating displays. Modern science reveals that elephants are not merely creatures of grandeur but vital ecosystem engineers…

#PrimatesAreNotPets: A social media animal welfare campaign

Have you ever seen “#PrimatesAreNotPets” floating around Twitter and other social media platforms? There’s a good reason this hashtag is becoming more prominent on the internet; primatologists, animal welfare activists, and conservationists are pushing to bring attention to the illegal pet trade and the devastation that it wrecks on the animals and their natural habitats. Primates aren’t the only exotic animals affected by the illegal pet trade, but they provide an excellent example of what removing a species from an ecosystem can do both at home and in the wild…

Back to the Stone Age: Monkey see monkey do

Primate archaeology is a fast growing field. While archaeology usually refers to the study of the human past through the excavation of past tools, remains, and civilizations, primate archaeology unearths the technological (tool use) past of our primate relatives as well as observes tool use by primates in real time. Each year, scientists make new discoveries about primates and their behaviors that prompt questions about the full extent of our primate relatives’ cognition and how it relates back to our own cognitive evolution…

What you might not know about keeping animals: Misconceptions about zoos

Zoos, aquariums, and animal sanctuaries are really important because they support animal conservation, species survival, insightful animal research, and educational programs.  However, there’s a lot of misinformation and misconceptions about zoos and animal sanctuaries that animal activists, such as PETA, use in order to deter people from enjoying, learning from, and supporting facilities that house wild animals…

A beginner’s guide to Bloomington birds

Step outside in Southern Indiana and you’ll be greeted by a symphony of chirps, calls, and songs from a myriad of local birds. Home to over 400 species, Indiana is a birder’s paradise. Warblers, eagles, and owls alike call Bloomington home and are frequently spotted on the campus of IU Bloomington. Birds are a vibrant part of Bloomington culture, so it’s worth getting to know a few…

Do chameleons change their color to match their environment?

[An animated GIF is shown featuring Pascal from Tangled, looking stressed and breathing deeply as he changes from his natural green state to match his background, a painted pot featuring flowers with a yellow center, teal petals, and green stems. His face becomes the yellow center or a flower, a teal petal in the center of his chest, and his tail is a green stem.]

Hopefully, we’ve all seen Disney’s Tangled, featuring the cute little chameleon Pascal. Throughout the film, Pascal takes on a range of colors depending on his background as well as his emotions. We see him blending in with teal walls and purple flowers, but we also see him turning red with anger. We’ve grown up thinking chameleons are able to blend into any background, but you may be wondering, is this true? Do chameleons really change their color to match any background or emotion?

Science with Nemo: Ethics of Care in Animal Research

We are all familiar with the plot of Finding Nemo: a scuba-diving dentist takes a small clownfish, Nemo, from a reef, keeps him in a fish tank in his office, and Marlin (Nemo’s father) goes on a whirlwind adventure to rescue his son. Obviously, Disney’s creative fiction is just that — fiction. However, many millions of fish are kept in tanks in the real world, for both recreation and research. Although we cannot know the fate of home-kept fish, for fish used in scientific research, there are specific rules for ethical treatment and proper care for fish of all kinds. How and why do scientists use fish in research anyways? 

Animals play a key part in concussion research

Posted by

[ ]

Currently, there are no effective treatments for concussions. People typically heal over time. Doctors treat the symptoms (e.g.. headaches, concentration problems, trouble sleeping, memory), but do not tackle the actual problem (i.e., how the injury affects certain functions of the brain). This is due to the inability to see what is happening to the brain as it receives a concussion. Because of that, researchers use animal models (e.g., lab rats, mice, etc.) to assess how the brain is affected by concussions.

Ethics in Research: What is the IACUC?

The Animal Welfare Act of 1966 was brought about by two major media publications. In Sports Illustrated, Pepper, the Dalmatian, had disappeared from her family’s front yard, only to have been found at an east coast hospital and after having been euthanized, following an experimental medical research study involving an early model of a pacemaker. Pepper had been snatched from her owner’s front yard, and then sold for use in medical research, all without their knowledge…
