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?

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…
Ethics in Research: What is the IRB?

Across many fields, scientific research involving humans has a dark history, and many studies conducted in the past are completely unethical both in their original contexts and now. In America, examples include the Tuskegee Study on syphilis, which ran for over 40 years, and Henrietta Lacks’ ovarian cancer cells which were used in scientific research for decades without her or her family’s knowledge…
Science without a Degree: What is Citizen Science and How to Get Involved
Louis Pasteur once said, “Science knows no country, because knowledge belongs to humanity, and is the torch which illuminates the world.” The act of doing science should not, and cannot, be confined to people in lab coats with multiple degrees squinting at computer screens and scribbling on whiteboards. Exploring the natural world around us should be something everyone can take part in, and that’s what citizen science is…

This year the largest ever study on the health risks of alcohol was released, attracting mass media attention and igniting a science journalism furor over its interpretation. In the study, researchers found a significant increased in risk of death for individuals who consume even one drink a day…. Read more »
The Research Domain Criteria (RDoC) initiative: A brief look
Even for non-researchers, it is important to be informed about the various initiatives that change the way we do science and, ultimately, the way scientists choose to spend government dollars. In the wake of the 10-year anniversary of RDoC’s inception [1], I would like to unpack this commonly misunderstood acronym that is popping up in… Read more »
Obstacles to the Stars
Taking astronomical images can be a very rewarding process—in part because of the gorgeous images you take, but also in part because of all the obstacles that can prevent you from observing the skies. We can protect our telescopes in buildings during the day to keep them clean and dry, but when night comes and… Read more »
Blood, sweat and fingerprints: the science behind crime scene investigation
We’ve all seen it on a TV crime series – fingerprints taken from a crime scene are put into a computer, instantaneously matched to a person of interest, and “Voila!” The crime is solved. As with many aspects of TV crime drama, however, fingerprint analysis is more complicated in real life. The reason? According to… Read more »
