Bivalves from Panama for Dermo disease study

Last week Nature magazine published a news piece about how supplies of agar, a research staple in labs around the world, are dwindling. Agar is a gelatinous material from red seaweed of the genus Gelidium, and is referred to as ‘red gold’ by those within the industry. Insiders suggest that the tightening of seaweed supply is related to overharvesting, causing agar processing facilities to reduce production. Most of the world’s ‘red gold’ comes from Morocco. In the 2000s, the nation harvested 14,000 tons per year. Today, harvest limits are set at 6,000 tons per year, with only 1,200 tons available for foreign export outside the country. In typical supply and demand fashion, distributor prices are expected to skyrocket. As a result, things could get tough for scientists who use agar and agar-based materials in their research.

Agar is a scientist’s Jell-O. Just like grandma used to make Jell-O desserts with fruit artfully arranged on top or floating in suspended animation within a mold, scientists use agar the same way. Bacteria and fungi can be cultured on top of nutrient-enriched agar, tissues of organisms can be suspended within an agar-based medium and chunks of DNA can move through an agarose gel, a carbohydrate material that comes from agar. Agar and agar products are the Leathermans of the science world.

It was believed that orchids sprang up wherever animals had been mating. And in Victorian England, women weren’t allowed to have orchids because the form of them was thought to be too erotic and too sexual, and it would be too much for a woman to bear, having a flower that sexual in her possession.”
-Susan Orlean, transcripts from NOVA’s
“Orchid Hunter”

There’s no denying, orchids are pretty darn sexy plants. And it because of their sex appeal, they’ve sashayed their way into just about every aspect of pop-culture. They’ve glammed their way into movies, TV, music, fashion and literature, and we didn’t even realize the spell they cast until it was too late. Bewitched, bothered and bewildered, we didn’t even realize how inescapable they are in our world. Here we explore a few examples of how orchids deftly made their way into pop-culture literature.
