Fun Science FRIEDay – Think water comes in just liquid, ice and gas? Think again!

Posted on November 17, 2017 By Kersey Sturdivant
Uncategorized

One of the most basic things that we learn when growing up is that water can exist in 3 different states of matter: as a gas (water vapor), as a liquid (water… water), and as a solid (ice). This basic and fundamental concept has recently been turned upside down as scientist have discovered that water might also exists in a fourth state; liquid water it appears might actually come in two different states. A collaborative team of researchers led by Dr. Laura Maestro at Oxford University, found that the  physical properties of water changed their behavior between 50 and 60℃ potentially changing to a second physical state of water.

Shark species names and hurricane sharks: Dear Shark Man, Volume 2

Posted on November 15, 2017 By David Shiffman

Welcome to volume #2 of Dear Shark Man, an advice column inspired by a ridiculous e-mail I received. You can send your questions to me via twitter (@WhySharksMatter) or e-mail (WhySharksMatter at gmail).


Dear Shark Man,

I know how you feel about sandbar sharks (even though I’m still #teamgoblinshark), but can we agree that Ninja Lanternshark is the best common name for a shark? Also, if you had an opportunity to name a shark, what would you name it? I’d name mine Storm Shark, not because of the meteorological event, but because Storm is Aquaman’s mighty seahorse steed.

Sincerely,
La Requin in Lake Buena Vista

Dear La Requin,

Ninja Lanternshark is a pretty sweet common name. My friend Vicky Vasquez was involved in the discovery and description of that species, which also has a cool scientific name (benchleyi, named after Jaws author and eventual shark conservationist Peter Benchley). If you haven’t read the great Hakai magazine story about this species, you should.

As an ecologist and conservation biologist, I am unlikely to get the opportunity to name a shark, but that doesn’t mean I haven’t thought about this. I’d love to see shark species named after influential shark conservation advocates, particularly those who engage in science-based conservation advocacy. If a new species of cownose ray is discovered, I hope that folks will consider naming it after Shark Advocates International President and frequent Southern Fried Science guest blogger Sonja Fordham, for example. And I certainly wouldn’t turn down a species named after me, if any taxonomists are reading this, though there are certainly plenty of more deserving people.

Incidentally, I have a colleague who studies marine mammal parasites. I’ve told her that I will donate to a conservation charity or her choice if a parasite that significantly annoys (but does not kill) dolphins is named after Southern Fried Science.

Shark protections, shark careers, and sharky grammar: Dear Shark Man, Volume 1

Welcome to volume #1 of Dear Shark Man, an advice column inspired by a ridiculous e-mail I received. You can send your questions to me via twitter (@WhySharksMatter) or e-mail (WhySharksMatter at gmail).


Dear Shark Man,

Have you seen this New Scientist article (“Sharks now protected no matter whose waters they swim in?)
Is this good news? It seems too good to be true.

Sincerely,
Skeptical in Seattle

Dear Skeptical,

You are correct to be, um, skeptical. At best, this article is an oversimplification of a very complex problem. Many shark species migrate through the territorial waters of multiple nations, which complicates any conservation and management plans for these species. The Convention on Migratory Species, which is what the New Scientist article is about, is an attempt to help. However, a CMS listing is only the first step, and it does not inherently require any legal protections. Thus far, CMS listings for sharks have not resulted in any concrete legal protections for these species. The World Wildlife Fund’s shark expert, Ian Campbell, has written a great summary of why this CMS news is not the be-all end-all solution that many seem to believe, check it out here:

Surviving a Double Hurricane (a first person report of the Puerto Rico disaster by Heather Cooke)

Posted on November 6, 2017November 6, 2017 By Guest Writer
Uncategorized

Heather Cooke graduated with an environmental science degree from George Mason University and studied marine biology. She is now a dive instructor and runs Culebra Divers on Culebra Island. This article was written during brief moments of power on Culebra Island.


As General Manager of Culebra Divers in Culebra, Puerto Rico for the last 2.5 years, I have enjoyed our semi-arid island with its brief storms. Known for one of the safer harbors in the Caribbean, my husband and I watched tropical storm after tropical storm and hurricane after hurricane pass us by. What I am writing is based on our experiences and what others around me have experienced or shared from their families on our sister islands.

Culebra the smallest of 3 islands that make up what you know as Puerto Rico (the “mainland”, Vieques, and us) and we’re 17 miles from the mainland itself.  To get here you fly from San Juan or take a ferry from the mainland’s east coast. We get all our food and fuel via that same ferry system. Our water and power travel under the ocean from the mainland through Vieques and then to us so if anything happens to either of those islands, we are screwed.  The island has a rag tag rental generator and no desalination plant.

As I write this, it has been 34 days since Maria and 48 since Irma and we still lack non-generator power, reliable daily water, and cell service not provided by some other island.

Fun Science FRIEDay – Life After Death

Posted on October 20, 2017October 20, 2017 By Kersey Sturdivant

That ominous specter of death. The one certainty in life that we are all careening towards. But how much do we really understand about death? Medically death is defined as the moment the heart stops beating and cuts off blood to the brain. Within seconds after heart failure the brain’s cerebral cortex — the “thinking part” of the brain — slows down instantly and flatlines (meaning no brainwaves are visible on an electric monitor). This initiates a chain reaction of cellular processes that eventually results in the death of brain cells; as a result the brain’s functions also stop and can no longer keep the body alive. The big question is after the heart stops beating, and both heart and brain activity flatlines, how quickly does cognition or awareness fade? A relatively recent study  suggests that consciousness continues even after death.
