Has CSI jumped the shark?

October 20, 2010October 19, 2010 David Shiffman 7 Comments

In the language of television reviews, the phrase “jump the shark” refers to a show that has been on the air too long and is out of good ideas. The original use refers to an episode of Happy Days where Fonzi literally jumped over a shark while waterskiing. A recent episode of CSI made me question if they are guilty of this same phenomenon. In episode 2 of season 11 (yes, the show has been on the air for 11 years), a woman is attacked by a shark. CSI watchers know that the show takes place in Las Vegas, Nevada, an unusual place for a shark attack. As it turns out, the shark attack took place in a Vegas hotel swimming pool. I’m not joking. Check out the preview:

We are now a little more than a week into the Donors Choose science blogger challenge. Ocean and geology bloggers have united to raise money for worthy science-related projects in public schools throughout the country.

Every few days, we’ll be highlighting a specific project from The Gam Classroom Initiative, though you can donate to any of our favorites from our Donors Choose Page.

Ethical debate: Can an endangered species be a business partner?

Conservation

Two of the strongest environmental laws in the world are the Endangered Species Act and the Marine Mammal Protection Act. Among many other statutes, these laws make it a Federal crime for anyone to harass endangered marine mammal species such as the West Indian manatee. By the accepted definitions of the word “harass”, this means that people cannot swim with and certainly cannot touch a manatee. However, at Crystal River National Wildlife Refuge in Florida, visitors can do both of these things- and it’s totally legal!

The Tea Party’s disturbing views about science

I know many scientists who aren’t politically active because they feel that many political issues don’t apply to them. I strongly disagree. If the upcoming midterm elections proceed as pundits claim, it may have disastrous consequences for American science policy. We all have a stake in this.

Altered sea turtle sex ratios: Can global warming harm warm-water animals?

Conservation, Science

When most people think of an animal threatened by global warming, images of a polar bear drowning because of lost ice habitat come to mind. Few know that climate change can also threaten animals used to living in environments much warmer than the Arctic. Even when you’re used to heat, too much heat can be a serious problem- particularly in vulnerable early life history stages.

One example of this phenomenon is the sea turtle. Though one species (the leatherback) often ventures into Arctic waters, the other species are largely confined to tropical and temperate climates. All seven species are threatened or endangered due to decades of bycatch mortality and habitat destruction, and they are in serious trouble as a result of warming beach temperatures.

Frito Lay abandons eco-friendly SunChip bags

Last year, Frito Lay unveiled a 100% compostable bag for SunChips. Since packaging waste from single-serving junk food is a sizable chunk of our society’s trash, this move was a big deal and was cheered by environmentalists. They even had a sappy commercial showing how this could make the world more environmentally friendly. Remember the commercial?

How not to apply for a job working with sharks

This week marked an important e-mail milestone for me: I received my 100th request for a job. I do not mean job offers (i.e. people saying “David, we’d like to hire you”), or requests for job advice (i.e. people saying “David, can you point me in the right direction?”). I’d be thrilled to answer any of those e-mails (particularly the job offers). I mean job requests (i.e. people saying “David, please hire me”).

I get all kinds of e-mails from readers, and I’m always happy to answer them. However, I would be remiss if I didn’t point out that applying for a job in this way is incredibly ineffective. I thought I’d take some examples from some of my favorite job request e-mails to explain to you all how not to apply for a job working with sharks.

Return of the light bulbs?

Two weeks ago, I mentioned the strange “save the light bulb” movement, prompting Andrew to write an excellent analysis refuting their central claim. For some reason, this issue is really bothering conservatives and it just won’t go away.
