Seawater contains sulfate concentrations that are nearly 40 times those measured in plasma. Therefore, it is easy to see why fish would need to develop mechanisms to keep sulfate within a physiologically normal range. The kidneys of teleost fish have been known to excrete excess sulfate in the urine. However until now, it was not known whether…

Mystery of the buzzing ocean discovered

I love a good mystery. This one has puzzled scientists for several years now…ever since they discovered a humming or buzzing noise in the Pacific ocean, an otherwise rather quiet place. This was no ordinary noise, that they knew of. In a recent interview on NPR, Dr. Simone Baumann-Pickering, Scripps Institution of Oceanography (La Jolla,…

Sailing Spiders

Research published July 3 in the journal BMC Evolutionary Biology supports the idea that some species of spiders can catch the wind to “sail” across bodies of water, which they suggest might be why certain spiders seem to be all over the world. While some spiders were already know to catch the breeze to travel by air relatively…

The opah (Lampris guttatus), otherwise known as a moonfish, lives in the deep sea where warm blood can be advantageous. According to a quote from Nicholas Wegner (NOAA) posted in Live Science, “Increased temperature speeds up physiological processes within the bod. As a result, the muscles can contract faster, the temporal resolution of the eye is…

Few fish can survive the immense pressure of living in the deep sea. The Mariana Trench can reach around 36,200 feet deep with pressures of over 1,000 atmosphere. Scientists have placed landers at various depths ranging from 16,400-34,750 feet along the walls of the trench and have discovered what appears to be the “World’s Deepest…

Life under Arctic ice

Ever wonder what lies beneath the polar ice? Turns out several researchers did as well. This past July a team of scientists led an expedition designed to image life under sea ice. The video below was captured with the Nereid Under Ice (NUI) vehicle and shows brown algae living on the bottom of sea ice…

With the help of advice from a manicurist, Dr. Kate Mansfeld (University of Central Florida) has come up with a way to track hatchling sea turtles for the first time. After hatching, the turtles head straight for the ocean where they grow for about 10 years or so before returning to the same beach where…

Paleogeneticist Dr. Johannes Krause (University of Tübingen, Germany) and colleagues were interested in the origin of tuberculosis (TB) in the Americas. Since strains of TB found in the Americas are related to strains found in Europe, prior theories held that Spaniards may have introduced it to the Americas while colonizing South America.  The problem with…

Killer sponges

Sounds kind of like an oxymoron doesn’t it? Who knew sponges could be carnivorous? Scientists have described four new species of carnivorous sponges in a newly published article in Zootaxa. Check out this video from the lead author of the study, Lonny Lundsten who is a Senior Research Technician at the Monterey Bay Aquarium Research…
