Why doesn’t magenta appear in the rainbow? The answer lies not in physics but in biology.

What happens when you decrease the pressure around a liquid? It boils. Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature of the liquid. The fastest molecules escape, leaving the slower ones behind.
Scientists in a new study they figure out what people see as they dream, using an MRI machine, a computer model and thousands of images from the internet.
When water is added to quicklime, a fierce exothermic reaction takes place as calcium hydroxide, slaked lime, is formed.
A new species of tarantula named Poecilotheria rajaei, roughly the size of a dinner plate has been discovered in a Sri Lankan village.
Scientists at the University of California Los Angeles have found a way to create stunningly detailed 3D reconstructing of platinum nanoparticles at an atomic scale. These are being used to study tiny structural irregularities called dislocations. Read the paper here:http://dx.doi.org/10.1038/nature12009
In a new study, a team of scientists have shown that a single antibody shrinks variety of human tumors transplanted into mice, finding that anti-CD47 antibodies can dramatically inhibit the growth of human solid tumors by blocking the ability of CD47 to transmit the ‘don’t-eat-me’ signal to macrophages.
Researchers in the US have shown that the oxide coating on copper nanoparticles can be stripped away by light, exposing the metallic, catalytic copper core. The finding is potentially significant because the oxidation state of many metals dictates their catalytic characteristics, and the ability to tune the oxidation state could open the way to producing more versatile and efficient catalytic systems.
Our bodies and homes are covered in microbes — some good for us, some bad for us, and some just along for the ride. As we learn more about the germs and microbes who share our living spaces, TED Fellow Jessica Green asks: Can we design buildings that encourage happy, healthy microbial environments?
merrylin from Simon Lewis on Vimeo. Merrylin Cryptid collection is the study and documentation of the evolution and biology of unclassified species and research pertaining to prehistoric human and non human civilization. In 2006, a trust was set up to analyze and collate a huge number of wooden crates found sealed in the basement of [...]
