7:22 PM | Whales Can Only Taste Salty
Five basic types of taste exist: sweet, sour, salty, bitter, and umami. Most people are familiar with all of these except the last, umami, which is best described as a pleasant savory taste. These tastes occur because of receptors that occur on cells in the mouth. Genes dictate the presence and number of these cells […]

2:16 AM | The mysterious case of the missing manta bits
This spectacular picture has been doing the rounds of my Facebook network lately, of a Mr Bell at AMNH working on a manta ray specimen in 1917:   Woah, right?  Helluva fish.  Well, hold your horses there, Tex.  It’s actually a model.  I was a bit suspicious that the specimen was just so…perfect…so I dug around […]

I was lucky to […]

10:21 AM | Are swimming zooplankton driving ocean currents? Sort of.
Biomixing, where the ocean is mixed by swimming animals, has long been a hot topic in oceanography. Some people think all that biological flapping and stroking could be a major source of oceanic turbulence. Others, not so much. But a new laboratory study by M. Wilhelmus and J. Dabiri from Caltech is certainly going to ignite scientists love […]

6:08 PM | The Reefs of American Samoa: A Story of Hope
[php]Sometimes called the rainforests of the sea, coral reefs are incredibly diverse and complicated systems. Because of this complexity, it can be a challenge to manage and protect reefs—and sometimes multiple threats must be addressed in quick succession. Overfishing, pollution and coral predators all have negative impacts on coral and the many animals that live on the reef. But with vigilant protection and response to these challenges, coral reefs can be protected. The story of […]
