Snorkeling snails

Scientists have been wondering why Asian Alycaeidae snails have a snorkel that was seemingly functionless. While other snails that live on land have a similar tube with an opening that allows them to breathe while inside the shell, the end of the breathing tube (i.e. snorkel) on the Asian snails appeared to be sealed. A new study published…

The trouble with lights

A new study published in Current Biology presents data showing that persistent exposure to artificial lights causes mice to age prematurely. Not only did exposure to bright light alter circadian rhythm, mice living in 24 hour light lost bone density and developed inflammation and weakness in their muscles. Humans are not immune to the effects of…

Ducklings are rather well-known for their ability to imprint on someone (usually their mother) or something shortly after hatching. Researchers at the University of Oxford were interested in understanding more about learning and memory in ducklings. Specifically, they wanted to know if a duckling simply remembered what they saw or if they were capable of more complex cognition…

Teleost fish living in saltwater environments are constantly compensating for water loss. This happens because their surroundings have higher concentrations of salts than their plasma and the rule of thumb in Biology is: water follows salt.  Thus these fish must somehow compensate for water loss in order to prevent dehydration. One way they do this is by…

Researchers at Stanford University have accomplished what was once considered impossible. They have partially restored vision in blind. Check out this Youtube video to see how they did it

During hibernation common hamsters (Cricetus cricetus) alternate their time between bouts of torpor during which their metabolic rate drops and body temperature is low and arousal during which body temperature is normal. Hibernation allows animals to conserve energy although it is not without costs as it often results in memory deficits, cell damage and reduced immune function.…
