Evolve Electroformed Copper, Vitreous Enamel, Sterling, Pearls, Lens, Feathers, Steel, Worm Photo: Courtney Frisse Last week I featured electroformed copper pendants by Kristina Glick Shank. I also found another outstanding electroformed copper artwork, this one by Kristin Mitsu Shiga. I think it's a wonderful idea to portray a chrysalid, the very symbol of transience, in metal - one of the most permanent materials possible. I am sorry it's titled Evolve - I don't love it when the concept of evolution is conflated with the concept of individual development. But this piece is so interesting…
When I think of molecules, I think of Conan O'Brien doing his skit where he plays Moleculo... the molecular man! I don't think of astronomy, and I certainly don't think of the leftover radiation from the big bang (known as the cosmic microwave background)! But somebody over at the European Southern Observatory put these two together and made an incredibly tasty science sandwich. See, we can measure the cosmic microwave background today, because we have photons (particles of light) coming at us in all directions at all locations, with a temperature of 2.725 Kelvin. Theoretical cosmology…
What the heck has this world come to? All over the internet, this picture of an Orangutan trying to fish with a stick has been shown: But what's the story behind this? Is this evidence that humans are not unique among the Great Apes as tool-users? Not quite. According to the Daily Mail, this is an orangutan that had extensive exposure to humans; this jungle setting is actually where they reintroduce orangutans into the wild from zoos, private homes and (yikes) butcher shops. This particular orangutan actually doesn't successfully know how to fish; this was something he copied from nearby…
The American Association of Physics Teachers just published a study of 1,000 likely U.S. voters about science, religion, evolution, and creationism. The results are frightening. Here are some of the "highlights" of their study: 38% of Americans are in favor of the teaching of religion in public school science classrooms. 65% of Americans do not think that it is an important science goal to understand the origin and diversity of biological life on Earth. 47% of Americans believe that the earliest humans lived at the same time as the dinosaurs. 21% of Americans do not believe that the…
What is the future of this website? I'm going to be creating videos for the web about the Universe. I'll be answering questions ranging from what the Universe is like today to how it got to be that way. I'm going to address every step that we know of, from the Big Bang up to the present day. And I'm going to do it naturally, by telling the story as the Universe tells it directly to us. I call this project Genesis. Check out the teaser trailer below, and tell your friends, because this is coming in January.
This is some very basic biology: when resources are unlimited and there are no pressures on a species, its population grows exponentially. There's also no evolution other than random mutations; without selection pressures (regardless of whether it's natural or artificial), the genetic information content of a species doesn't change appreciably. Biologists make use of this to perform tests on certain cells. If you simply put a population of cells in a petrie dish and left them there, they start out by doing this: They divide. They take over the dish. But then, they run out of room. And when…
