Nearly All Vertebrates Descended From Ancestor With Sixth Sense
2011-10-12 04:49:05

A new study finds that sharks, paddlefishes and certain other aquatic vertebrates have a sixth sense: the ability to detect weak electrical fields in the water, and to use this information to detect prey, communicate and orient themselves. The study, which caps more than a quarter century of work, found that the vast majority of vertebrates — roughly 30,000 species of land animals (including humans) and a roughly equal number of ray-finned fishes — descended from a common...

Sharks are in big trouble on the Great Barrier Reef and worldwide, according to an Australian-based team who have developed a world-first way to measure rates of decline in shark populations. “There is mounting evidence of widespread, substantial, and ongoing declines in the abundance of shark populations worldwide, coincident with marked rises in global shark catches in the last half-century,” say Mizue Hisano, Professor Sean Connolly and Dr William Robbins from the ARC Centre...

(Ivanhoe Newswire) -- A compound that was initially isolated from sharks may serve as an antiviral treatment, according to a new study. The compound -- known as squalamine -- has been studied in human clinical trials for treating cancer and eye disorders. In both lab and animal studies, the compound showed antiviral activity against human pathogens. "To realize that squalamine potentially has broad antiviral properties is immensely exciting, especially since we already know so much from...

  Campaigns to save shark species have progressed in the past week as the California State Senate passed a ban on the sale and possession of shark fins last Tuesday.

Shark fins are harvested from sharks in the ocean by catching the species, and then cutting off their fins, only to toss them back into the ocean for the animals to bleed out and die. "Since the 1970s the populations of...

Shark populations over the last 50 years have decreased dramatically. From habitat degradation to overfishing and finning, human activities have affected their populations and made certain species all but disappear. A new article in Current Issues in Tourism by Austin J. Gallagher and Dr. Neil Hammerschlag of the R.J. Dunlap Marine Conservation Program at the University of Miami study the impact of these apex predators on coastal economies and the importance of including conservation efforts...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
