12:00 PM | Using Pain To Stop Pain
Biology concepts – desensitization, habituation, counter irritation, cautery, heat sensing, pain, chronic, acute, analgesiaGout usually attacks middle-aged men and the big toe joint is a favorite spot. But it can occur anywhere and in anyone. The accretions or urates build up and clog the joint, causng poor function and intense pain, painful enough that even the weight of a sheet on it at night is too much. Usually the acute attacks are far worse, and become less painful gouty arthritisas […]

10:13 AM | Tiger sharks: Each to their own diving depth
Despite some broad similarities, the diving behaviour of tiger sharks appears to vary greatly amongst individuals.  Tiger sharks (Galeocerdo cuvier) are one of the top predators in tropical and subtropical waters throughout the world. These large sharks are known to occupy both coastal and open seas, and can travel over both short and long distances. […]

The case of the vanishing honeybees In the past decade, the US honeybee population has been decreasing at an alarming and unprecedented rate. While this is obviously bad news for honeypots everywhere, bees also help feed us in a bigger way — by pollinating our nation’s crops. Emma Bryce investigates potential causes for this widespread colony collapse disorder.

The Science of Dancing Animals Yes, really. You’ve seen animals swaying and rocking to music in online videos, but can they truly dance on their own to different kinds of music? This means no human intervention, training, or mimicry- the rhythmic moving must be autonomous. The list gets narrowed down by a lot, but experiments showed that 2 species seem to be able to dance. Why? What purpose does dancing even actually serve? Kim Horcher and Christina Ochoa (Scirens and Chaotic Awesome) […]

3:18 PM | Telomere length: a new measure of chronic stress in wildlife? | @GrrlScientist
Two independent studies find a positive relationship between social environment and telomere length. The first study -- that nearly everyone has heard about -- is in children. The second study -- that few have heard about -- is in pet grey parrots. The second study raises the question: might telomere length be developed a new way to measure chronic stress -- in animals? Telomeres, the DNA-protein caps that prevent chromosomal fraying, are positively affected by social stress, according to two […]

During the larval stage, the caterpillar must consume vast quantities […]
