5:38 PM | Mélange et Trois: A Trip Across Subduction Zone Madness

Few places on Earth are so full of geological mayhem as a subduction zone. Life in the interior of a continent in no way prepares you for the chaos you’ll encounter when seafloor dives under continent. Where I grew up on the Colorado Plateau, the geology’s like a lovely layer cake: nice horizontal slabs of [...]

Video Tip of the Week: Canary Database for sentinels of human health

Recently we attended the Medical Library Association conference (#MLAnet13). Librarians are working so hard to wrangle information into usable forms, and to generate new connections among data types to reveal new information and leads for further studies. I ♥ librarians. In one of the sessions I attended on Medical Informatics, I heard several great talks. One [...]

We Didn't Know This about Iron Before

It's amazing that we're still discovering things about our own planet at a time when we have the technology to explore planets other than our own. A study that was published in Nature Geoscience last week found that iron is weaker than previously thought. What's interesting about this is that we didn't know before this experiment how iron acted at high pressures, like those found in Earth's core.What we know about the composition of the center of the Earth is just made from inference. The […]

Gran Sasso, Solar Neutrinos, and Radioactive Decay Rates

We interrupt your normal coverage of magnetic monopole searches today to bring you something much more cool from well.. the same location! I was jazzed to find out yesterday that the next monopole project I was going to write about was done at a stunningly pretty location Gran Sasso, Italy. (picture 1)Then, thanks to +Oliver Thewalt I found out about a very interesting study done regarding a possible time dependence of the decay rates of radioactive isotopes. So much for the […]

Berkeley Lab Builds ‘Artificial Forest’ to Harvest Solar Energy

Devices for artificial photosynthesis are often called “artificial leaves”. This leaves, however, are of no use unless you can create an “artificial forest” from them. Now, scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory have reported the first fully integrated nanosystem for artificial photosynthesis. Read more »
