Panspermia is the name for the theory that life exists and is distributed throughout the universe in the form of germs or spores. This short computer animation places the viewer in the middle of a virtual world of an aggressively reproducing inter-galactic life form, and depicts a single life cycle of this unusual self propagating system.
"As Discovery launches a network-wide push entitled Bees on the Brink , we're turning our attention back to honeybees, the challenges they face, and what we can do to help them. From the deep dependence of our food system on honeybees to the shocking decline in bumblebee populations, the case that pollinators are facing a crisis is hard to refute. But intellectual arguments only go so far. Sometimes we just have to take a step back and marvel at the beauty that nature presents us with. Film maker Louie Schwartzberg has been capturing stunning time-lapse cinematography of pollinators ranging from bees to bats for years. It is, he says, a reminder of our connection to the web of life. "We'll protect what we fall in love with" he argues. Let's just hope he's right." by Sami Grover
Windowfarms let you grow food year-round inside while maximizing space. They are vertical food-growing gardens that use a dirt-free technique called hydroponics. You can buy a kit or build your own using low-impact or recycled local materials. Having a windowfarm is more about the activity and experience of windowfarming, these are living systems, not just a pretty thing to look at.
This site is the online community of windowfarmers around the world. Together, we are continually getting better at growing food in the local conditions of our own homes. We are contributing to the “green revolution” as non-experts. We call it R&D-I-Y, or research and develop it yourself. We use this site to collaborate on evolving designs for these vertical hydroponic systems– proposing experiments, testing techniques, and developing a shared knowledge base around the many variables involved in building and maintaining a farm inside a city apartment. Welcome!
"NASA's Chandra X-ray Observatory reveals the complex X-ray-emitting central region of the Crab Nebula. This image is 9.8 light-years across.
The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object. On April 12, NASA’s Fermi Gamma-ray Space Telescope first detected the outburst, which lasted six days. Several other satellites also made observations, which has astonished astronomers by revealing unexpected changes in X-ray emission the Crab, once thought to be the steadiest high-energy source in the sky."
