A study recently published in the Proceedings of the National Academy of Sciences provides evidence that pigeons can learn to recognize words. That is after the birds were trained over a period of 8 months. According to the study authors “The pigeons’ performance is actually more comparable to that of literate humans than baboons’ performance.” To read, we must be about to decode letters and the sounds they make as […]

Drumroll please….. Out of roughly 18,000 new species discovered this past year, the International Institute for Species Exploration at SUNY College of Environmental Science and Forestry has narrowed down the top 10 to the following: I am rather partial to tortoises myself. What were your favorites?
We tend to think of carbon monoxide (CO) only in terms of being a poisonous gas. The reason for its toxicity is due to its ability to bind really tightly to our hemoglobin molecules, which prevents oxygen from being able to bind. In mammals, CO also decrease breathing rate. As you can imagine, it is a pretty terrible gas to breath in when you are a species dependent on hemoglobin for delivery […]
New research presented at the British Ecological Society, Liverpool shows that reindeer are shrinking. These findings come from a survey conducted between 1994-2010 in Svalbard, a Norwegian island, which found the animals have lost about 12% of their body mass over this timeframe. The research team thinks the shrinking reindeer phenomenon might be caused by global warming as females have increased access to grasslands and give birth to more calves annually than in […]
… or any other human language for that matter. Even though both monkeys and humans have the anatomical tools for speech, only humans communicate in this manner. Researchers had assumed, incorrectly, that the anatomy of the vocal tract (lips, tongue, larynx) of monkeys was not capable of producing speech. A new study published in Science Advances shows instead that it is all in our heads. The researchers came to this conclusion after creating x-ray videos […]
A changing climate has the potential to greatly impact ectotherms, which depend on the environment to regulate their own body temperatures. In a new study published in the American Journal of Physiology- Regulatory, Integrative and Comparative Physiology, researchers were curious how exposure to varying temperatures would affect developing ectotherms. They answered this question using Drosophila melanogaster, commonly known as fruit flies. They exposed freshly laid eggs to ten different temperatures ranging from 12 […]
I came across a neat article in Scientific American that described how reindeer and elk regrow their antlers every year. Could you imagine putting that much energy into growing new bone each year complete with a velvety cover containing nerves, skin, and blood vessels? Although full-grown antlers lose their blood supply and animals scrape the velvet layer off to reveal just bone. Researchers have explored whether understanding this amazing process of […]
