We’ve all seen the humorously scatterbrained black-and-blue fish Dory in Pixar’s Finding Nemo, but only those who have spent some time snorkeling or diving in tropical waters have seen the real-life surgeonfish–as that class of fish is called–just keep swimming in its natural habitat. Next year, Finding Dory will act as a sequel to the immensely popular aquatic animation film from 2003. Before you watch it in cinemas, you can learn a little about the actual fish that Dory is based on, via BBC Earth:
“I suffer from short-term memory loss,” Dory tells Nemo. “I forget things almost instantly, it runs in my family.”
It’s very funny and ultimately touching, but this depiction is just a little unfair. The fish Dory is based on does not have short-term memory loss. It is rather more awesome than that.
It has several names, including royal blue tang, regal tang and surgeonfish. Its scientific name is Paracanthurus hepatus.
We’ve featured a post solely dedicated to cranberry bogs in the past, and have also seen some of the classic holiday sauce as part of a Thanksgiving art celebration. Now, with Thanksgiving Day coming up in the United States on Thursday, we’re learning even more about the North American fruit from Science Friday’s Thanksgiving Science Spotlight:
There are certain things that might come to mind when thinking about cranberries: A certain shade of red, a certain small size, and a certain kind of tartness. But these characteristics can differ among cranberry varieties—of which there are more than 100, according to Carolyn DeMoranville, an associate extension professor and station director at the University of Massachusetts-Amherst Cranberry Station.
We have a special place for any citizen science project, no matter what kingdom of natural life it covers, or whether its accomplished at home or in the field. Now we’re learning about a new project covering trees from The Nature Conservancy’s “Cool Green Science” blog:
What Is i-Tree?
i-Tree is a Swiss army-knife collection of tools that people can use to measure the impact individual trees and forests.
In fact, the collection of tools is so comprehensive it can seem overwhelming. But don’t be daunted. Here’s the information you need to get started.
For citizen scientists, i-Tree Streets and i-Tree Pest Detection are two key instruments in the i-Tree arsenal. (Many of the other tools are designed primarily for city officials and forest managers.)
For each tree that you select to inventory, i-Tree Streets can estimate the tree’s effect on greenhouse gasses, air quality, and stormwater overflow. Find a group in your area that is conducting a tree inventory with i-Tree Streets. City governments and conservation organizations can collect the data for use at the local level.
A little over a year ago, James wrote about slacklining while here at Xandari, since we were both practicing the recreational activity a few times a week. Back in the day, we had to search far and wide for appropriate trees on which to anchor our line, finally settling for orange trees in the orchard that we rotated between. Since then, we have two special spots designed for slacklining at Xandari, one by the west pool, where the sunsets make for a great view (see left), and another down below the studio, where the line can be set up at a longer distance and the posts are strong enough to take some serious bouncing.
Our studio slackline, however, is nowhere near as long or strong as that which Théo Sanson walked in Utah last week. As you can see in the video below, he traversed a “highline” that must have been a thousand feet above the ground, anchored between two landmarks in the desert of Castle Valley. The music you hear in the background of the video happens to be one of my favorite soundtrack pieces, drawn from Ennio Morricone’s work for the western film The Good, the Bad, and the Ugly.
We’ve alluded to the Great Pacific Garbage Patch before, though we haven’t shared any stories covering it directly. Last week, The Guardian reported some good news from The Netherlands, where the prototype for a 100km-long, crowdfunded cleanup boom for the ocean was tested successfully. Arthur Nelsen reports:
Further trials off the Dutch and Japanese coasts are now slated to begin in the new year. If they are successful, the world’s largest ever ocean cleanup operation will go live in 2020, using a gigantic V-shaped array, the like of which has never been seen before.
The so-called ‘Great Pacific garbage patch’, made up largely of tiny bits of plastic trapped by ocean currents, is estimated to be bigger than Texas and reaching anything up to 5.8m sq miles (15 sq km). It is growing so fast that, like the Great Wall of China, it is beginning to be seen from outer space, according to Jacqueline McGlade, the chief scientist of the UN environmental programme (Unep).
I wrote about my daily “commute” in the first post I wrote upon arriving to Xandari as an intern. However, circumstances have changed since then (I am proud to say that I am officially a company employee now), so I think it’s only fair for me to share an updated version that not only illustrates my own personal account but also reflects that of many other employees of the hotel as well.
Last week a pair of scientists writing for The Conversation (a news source with what they call “academic rigor, journalistic flair”) and also Discover Magazine’s science blog discussed the merits of hair in keeping animals clean. We found it pretty interesting, and hope you will too:
Watch a fly land on the kitchen table, and the first thing it does is clean itself, very, very carefully. Although we can’t see it, the animal’s surface is covered with dust, pollen and even insidious mites that could burrow into its body if not removed.
Staying clean can be a matter of life and death. All animals, including us human beings, take cleaning just as seriously. Each year, we spend an entire day bathing, and another two weeks cleaning our houses. Cleaning may be as fundamental to life as eating, breathing and mating.
Yet somehow, cleaning has gotten little attention.
In our new review article in the Journal of Experimental Biology, we discuss how cleaning happens in nature and whether animals indeed have principles for getting clean. We looked at microscope images to count the number and sizes of hairs across hundreds of animals. We read nearly a hundred articles on cleaning in nature, trying to put numbers onto the cleaning process.
