Open Source Beehives

The Open Source Beehives project is currently running a crowdfunding campaign with the goal of gathering information from sensor equipped hives throughout the world to help solve bee population problems like colony collapse syndrome. The sensors can also be used by individual beekeepers to monitor the health of their hive.

Even without the sensors and the citizen science, their hive designs are beautiful.

Citizen Science: How Big is a Bird Egg?

emu egg in ostrich eggbot

While talking about egg sizes in the context of the Eggbot project, we realized that while we have access to a few samples, we do not have a good understanding of the normal variation in the sizes of various bird eggs.

The sizes of chicken eggs are well understood and well regulated, but for other types of bird eggs (like the emu egg above) the sizes are not necessarily so standard. If you have access to other types of eggs or eggshells, we’d like your help in gathering data about the size and variation in these other types of eggs.

We’ve set up a survey form to collect egg size data and we plan to post about our results once we have collected enough data.

Thank you!

Foul Play in the Floral Department

Untitled

While walking through Home Depot on an unrelated mission, we happened to walk by a display of succulents, and were struck by the unusual blue color of some of the flowering cacti.

But on closer inspection, we could see what was really going on: the flowers on the top were attached… with glue. In fact, most of the flowers on the cacti and succulents were glued on.  Some of them, like this winner here, even had globs of glue spilled down onto the spines of the cactus below.

This is a deceptive (yet sadly common) practice— and apparently many people do get fooled by it —as we found garden forum posts and warning articles about it, including here, here, here and here.  This seems not so far away from buying a fruit tree at a nursery, only to find out (once you get it home) that the fruit was only glued to the tree.

It looks like they are trying to make the less showy cactuses compete with the brightly colored grafted ones that they sell, like the ones shown pictured here. (This may not be a naturally occurring configuration, but at least it is a real, living plant.)

Strawflowers are used because they keep their color well after drying. They also open and close as the humidity changes and they absorb more water or dry out more, giving the illusion of being part of a living plant.

And if it’s not bad enough that the customer is being deceived about the nature of plant they are buying, the glue can often damage the plant below, especially during the removal process.

Time Lapse Fog over San Francisco

Adrift is a beautiful short film by Simon Christen chronicling the fog of the San Francisco bay.

I spent many mornings hiking in the dark to only find that the fog was too high, too low, or already gone by the time I got there. Luckily, once in a while the conditions would be perfect and I was able to capture something really special. Adrift is a collection of my favorite shots from these excursions into the ridges of the Marin Headlands.

Field Trips: Fern Canyon

Fern Canyon 6
Fern Canyon is a lush little feature of Prairie Creek Redwoods State Park— a tiny winding canyon whose dripping walls are lined with soft ferns and vibrant mosses.

The park is located very northwest corner of California, nestled against Redwood National Park.  The two parks are managed together, as part of the “Redwood National and State Parks.”  It’s a substantial six hour drive north from San Francisco or Silicon Valley, but as you will see, it’s unique, and arguably worth the trip.
