Could These Sharks Get Their Own Fan Clubs?

To coincide with the Discovery Channel's annual "Shark Week" series, Nova Southeastern University has launched a Web site that allows visitors to follow specially-tagged sharks as they swim around the world.

What's the Latest Development?


Thanks to the good folks at the Guy Harvey Research Institute at Florida's Nova Southeastern University (NSU), people who love sharks can follow 18 of them online as they travel Earth's oceans. Satellite-linked devices tagged onto the sharks allow scientists to record their migration patterns for as long as the battery holds out (between 10 months and two years). The NSU team has been tagging sharks since 2009 to track a variety of species, including tiger and mako, but decided to launch a Web site to coincide with this year's Discovery Channel's "Shark Week" series, which began on Sunday.

What's the Big Idea?

NSU is one of several universities and research institutions that seek to preserve and understand shark populations around the world. At least two -- Stanford University and the Marine Conservation Science Institute -- offer mobile apps that open a window into shark life. Visitors to the NSU site can learn about a mako named Carol, for example, who traveled from New Zealand to Fiji and back -- a total of about 10,000 miles -- in less than a year. They can also find out about sharks that move at speeds of up to 60 miles per hour and dive over 3,000 feet deep.

Strange Maps
  • Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
  • Wrong! Neither Venus nor Mars is the right answer.
  • Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury!

Horseshoe crabs are drained for their blue blood. That practice will soon be over.

The blood of horseshoe crabs is harvested on a massive scale in order to retrieve a cell critical to medical research. However, recent innovations might make this practice obsolete.

Surprising Science
  • Horseshoe crabs' blue blood is so valuable that a quart of it can be sold for $15,000.
  • This is because it contains a molecule that is crucial to the medical research community.
  • Today, however, new innovations have resulted in a synthetic substitute that may end the practice of farming horseshoe crabs for their blood.
