DNA from the Beginning -animated experiments DNA from the Beginning is organized around key concepts. The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links. DNAftb blog: It's the season of hibernation, something I've always wished I could do. Oh, to wrap up in a ball, sleep away the winter, and wake to a beautiful spring day – like Bambi! Although the thought has always intrigued me, it never really occurred to me what a feat hibernation actually is.

Discovery Education | Siemens Science Day Did natural selection make the Dutch the tallest people on the planet? AMSTERDAM—Insecure about your height? You may want to avoid this tiny country by the North Sea, whose population has gained an impressive 20 centimeters in the past 150 years and is now officially the tallest on the planet. Scientists chalk up most of that increase to rising wealth, a rich diet, and good health care, but a new study suggests something else is going on as well: The Dutch growth spurt may be an example of human evolution in action. The study, published online today in the Proceedings of the Royal Society B, shows that tall Dutch men on average have more children than their shorter counterparts, and that more of their children survive. That suggests genes that help make people tall are becoming more frequent among the Dutch, says behavioral biologist and lead author Gert Stulp of the London School of Hygiene & Tropical Medicine. For many years, the U.S. population was the tallest in the world. Just how these peoples became so tall isn't clear, however.
Beyond Penguins and Polar Bears Might Alien Life Evolve Like the Incredible Octopus? by Natalie Shoemaker Consider the octopus: a creepy skeleton-less creature with limbs that have regenerative properties and a mind of their own. Its structure — inside and out — makes it like no other animal on earth. As a part of the Mollusca phylum, the octopus seems so far removed from its clam cousin. Neurobiologist Benny Hochner, from the Hebrew University of Jerusalem in Israel, talked about this oddity in an interview with Alison Abbott from Nature: “Very simple molluscs like the clam — they just sit in the mud, filtering food. Scientists have marveled at the octopus for years, and now they've taken the time to delve deeper into its biology by decoding its genome. "The octopus appears so utterly different from all other animals, even ones it's related to, that the British zoologist Martin Wells famously called it an alien. “It’s important for us to know the genome, because it gives us insights into how the sophisticated cognitive skills of octopuses evolved.”
Stellarium DNA Deoxyribonucleic acid (DNA) is a long chain organic molecule that contains the coding for all metabolic and reproductive processes of all living organisms, save for certain viruses. This helix shaped molecule consists of a spine that contains a sequence of nucleotides, whose order comprise the coding instruction for each specific lifeform. DNA itself is not alive, but holds the instruction set for building a vast array of proteins as well as its own replication. A single DNA molecule contains all the information required to assemble any complete organism; in fact, the macro-structure of circular versus linear DNA geometry distinguishes biological domains (e.g. prokaryote versus eukaryote). DNA, of course, is not a single well defined molecule, but can occur in an enormous number of different codings, since, by its nature, any given DNA molecule contains the complete instruction set for an entire species.
