A question was submitted to our blog asking: “How does animal research advance medicine?” It is an important question, and I will do my best to answer it.
The average human life expectancy has increased dramatically over the past 100 years. In 1900, most did not live past 50. Now, most will live to see their 75th birthday. This increase is largely due to advances in medicine that would not have been possible without animal research.
In fact, many scientific organizations as well as the World Health Organization and the United States Department of Health and Human Services estimate that animal research has played a part in almost every major medical advancement over the past century. This fact alone underscores the importance that animal research has played in medicine.
Despite all the benefits of animal research in advancing medicine, many opponents of animal research ask the question, “What gives humans the right to use another creature for our own advancement?” It’s true that this is not a question with an easy answer. Every person has his or her own values and is entitled to his or her own opinion on that question.

“Alcohol makes you sleepy.”
We’ve all heard it. Many of us have experienced it. A few of us even swear by it—enough to ceremonially partake in a glass or two of wine before crawling into bed.
In fact, a little booze has been experimentally (and anecdotally) demonstrated to help us fall asleep faster and increase slow-wave, or deep, sleep in the first half of the night.
But its effect on other aspects of sleep—notably, the second half of the night—leaves little to be desired.
What causes alcohol’s strange and dichotomous effect on the sleeping brain? And the real question—do you accept the nightcap or not?

It’s that time of year again- the end of daylight savings and the beginning of the dark season. As is ominously stated in Game of Thrones: Winter. Is. Coming.
While the majority of us look forward to seasonal festivities, millions can also expect feelings of depression, fatigue, irritability and poor sleep.
This form of mental illness, commonly known as the winter blues, is Seasonal Affective Disorder (SAD). SAD is disproportionately represented in populations furthest from the equator. It is estimated that 1-2% of North Americans have a mood disorder with a seasonal pattern, with 10% of New Englanders versus 2% of Floridians affected. Symptoms of SAD include feelings of hopelessness, low concentration, sluggishness, social withdrawal, unhappiness and irritability.
Decades of research has uncovered the culprit behind this debilitating illness: lack of sunlight and disruption of circadian rhythms.
