Classification Why do we classify things? * Classification provides scientists and students a way to sort and group organisms for easier study. * There are millions of organisms on the earth! (approximately 1.5 million have been already named) Organisms are classified by their: * physical structure (how they look) * evolutionary relationships * embryonic similarities (embryos) * genetic similarities (DNA) * biochemical similarities Ten Simple Rules for the Care and Feeding of Scientific Data Citation: Goodman A, Pepe A, Blocker AW, Borgman CL, Cranmer K, Crosas M, et al.

What would disprove evolution? If evolution is a scientific theory worth its salt, then there must be some conceivable observations that could show it to be wrong. I just wanted to put down, for the record, what some of those observations might be. First, let’s reprise what I see as the major components of the theory of evolution.
Creative Routines “We all have the same 24 hours that Beyoncé has” and its various iterations took the web by storm in late 2013 as the megastar became the figurehead of not only having it all, but being able to somehow do it all too. How do creatives – composers, painters, writers, scientists, philosophers – find the time to produce their opus? Mason Currey investigated the rigid Daily Rituals that hundreds of creatives practiced in order to carve out time, every day, to work their craft. Some kept to the same disciplined regimen for decades while others locked in patterns only while working on specific works. Creative Routines Poster There are enough data to visualize a portion of the hundreds of creative lifestyles.
Animal Adaptations Being able to adapt is a matter of life or death. Animals who can't adapt - die! For animals, adaptation is the idea that animals have developed features that help them to survive and thrive where they live. Some adaptations are purely physical. Fish have fins to help them swim and gills that let them breathe underwater. The Fermi Paradox PDF: We made a fancy PDF of this post for printing and offline viewing. Buy it here. (Or see a preview.) Everyone feels something when they’re in a really good starry place on a really good starry night and they look up and see this: Some people stick with the traditional, feeling struck by the epic beauty or blown away by the insane scale of the universe.

Straw Bale and Hemp Construction Sam Atkinson LLP specialises in the design and construction of straw bale and hemp buildings. Our recent projects include a straw bale cottage, a straw bale bungalow, straw bale classrooms, a straw bale bird hide and a straw bale screen. You can also see more about our range of straw bale holiday accommodation at www.strawbalecabins.co.uk Straw is an abundant building material and offers a great many environmental advantages such as super insulation, energy efficiency and carbon storage. A straw bale building will last a very long time when designed appropriately and built well. You can read much more about the advantages of straw bale building by clicking through to this website www.homegrownhome.co.uk Myrmedrome - A real ant colony simulator MYRMEDROME is an ant colony simulator which tries to imitate the ants’ life as well as possible without introducing artificial effects. The simulation is based on the fundamental principle that each ant is not enough intelligent to understand it lives in a complex community, nor it is able to organize tasks in its colony. Therefore, each ant lives and works following some simple rules interacting (unaware of it) with the others by chemical signals. These thousands of connections rise a self-organization of the whole colony, which leads an observer to believe that someone imposed some kind of strategy.
The Earthquake That Will Devastate Seattle When the 2011 earthquake and tsunami struck Tohoku, Japan, Chris Goldfinger was two hundred miles away, in the city of Kashiwa, at an international meeting on seismology. As the shaking started, everyone in the room began to laugh. Earthquakes are common in Japan—that one was the third of the week—and the participants were, after all, at a seismology conference.
