Introducing the Knowledge Graph: things, not strings Cross-posted on the Inside Search Blog Search is a lot about discovery—the basic human need to learn and broaden your horizons. But searching still requires a lot of hard work by you, the user. So today I’m really excited to launch the Knowledge Graph, which will help you discover new information quickly and easily. Take a query like [taj mahal]. But we all know that [taj mahal] has a much richer meaning. The Knowledge Graph enables you to search for things, people or places that Google knows about—landmarks, celebrities, cities, sports teams, buildings, geographical features, movies, celestial objects, works of art and more—and instantly get information that’s relevant to your query. Google’s Knowledge Graph isn’t just rooted in public sources such as Freebase, Wikipedia and the CIA World Factbook. The Knowledge Graph enhances Google Search in three main ways to start: 1. 2. How do we know which facts are most likely to be needed for each item? 3.
Early Humans for Kids - A Quick Look at Ancient Man Homo Habilis, Cro-Magnon, Neandertal, these are some of the forms early man took. Some scientists believe that man in some form began about 3 million years ago. Unlike what the movies show, Early man did not live at the same time as the dinosaurs. Dinosaurs died out about 65 million years ago. In your study of early man there are going to be many new terms and words for you to learn. Hominids is a kind of slang term among scientists.

Natural Selection: How Evolution Works December 2004 What is natural selection, and how is it central to the theory of evolution? Natural selection is how species evolve by adapting to their environment. Natural selection explains design in nature. Charles Darwin studied beak variation of finches on the Galapagos Islands as evidence of natural selection. Futuyma: Natural selection is the process by which species adapt to their environment. The reason that natural selection is important is that it’s the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. Darwin’s book On the Origin of Species by Means of Natural Selection caused quite a stir when it appeared in 1859. Is natural selection the only mechanism of evolution? Evolution has several mechanisms. Genetic drift involves random changes. Futuyma: No, certainly not. Natural selection is more consistent, adaptive change. Does natural selection lead to new species, and if so, how? Futuyma: It sometimes does but not always.
The Omnivorous Mind — John S. Allen In this gustatory tour of human history, John S. Allen demonstrates that the everyday activity of eating offers deep insights into human beings’ biological and cultural heritage. We humans eat a wide array of plants and animals, but unlike other omnivores we eat with our minds as much as our stomachs. This thoughtful relationship with food is part of what makes us a unique species, and makes culinary cultures diverse. Drawing on the work of food historians and chefs, anthropologists and neuroscientists, Allen starts out with the diets of our earliest ancestors, explores cooking’s role in our evolving brain, and moves on to the preoccupations of contemporary foodies. To explain, for example, the worldwide popularity of crispy foods, Allen considers first the food habits of our insect-eating relatives.
Blue Planet Biomes - World Biomes What is a Biome? A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome. All living things are closely related to their environment. The earth includes a huge variety of living things, from complex plants and animals to very simple, one-celled organisms.
What is Evolution - history and definitions Evolution is a scientific theory that essentially states species change over time. There are many different ways species change, but most of them are based on the idea of Natural Selection. The Theory of Evolution through Natural Selection was the first scientific theory that put together evidence of change through time as well as a mechanism for how it happens. History of Evolution: The idea that traits are passed down from parents to offspring has been around since the ancient Greek philosophers' time. The late 1700s saw the first theories that species changed over time. John Baptiste Lamarck, a student of the Comte de Buffon, was the first to publicly state species changed over time. Cuvier believed in catastrophism, meaning these changes and extinctions in nature happened suddenly and violently. Darwin and Natural Selection: Sometimes called "survival of the fittest," Natural Selection was most famously explained by Charles Darwin in his book On the Origin of Species.
The future of UI Synopsis It's 10 years since Minority Report hit our screens. The film's science adviser and inventor John Underkoffler demos g-speak – the real-life version of the eye-popping, tai chi-meets-cyberspace computer interface that Tom Cruise used to whoosh through video clips of future crimes.

Boy finds 10,000-year-old arrowhead on New Jersey beach Noah Cordle, 10, found a 10,000-year-old Paleoindian arrow point on a New Jersey beach.Kelly-Jane Cotter/ Asbury Park Press BEACH HAVEN, N.J. – A boy playing on a New Jersey beach has unearthed a 10,000-year-old arrowhead possibly used by ancient Native Americans to spear fish or hunt mastodon. Noah Cordle, 10, and his family were vacationing on the Long Beach Island last week when he found it at the edge of the surf in the community of Beach Haven. It was sharp enough that it hurt as it hit his leg. He thought it was a crab until he picked up the object. The Springfield, Virginia family contacted the Archaeological Society of New Jersey to check it out. The president, Greg Lattanzi, who is also a curator at the New Jersey State Museum in Trenton, tells the Asbury Park Press that the arrow point probably dates back 8,000 to 11,000 years. "I was basically blown away," he said. Only one other in the collection washed up on a beach. "Jasper is a yellow-brown stone," Lattanzi told the paper.
(A few) transitional fossils untitled Source: Jouni A. Smed Introduction Much of the discussion of out-of-body experiences has centered around the recounting of experiences and speculation on the nature of those experiences. Some articles have questioned whether the experiences are of an hallucinatory nature or purely a function of biochemical processes that occur in the brain, and, at the other extreme, some have linked them with notions of the existence of an immortal soul and other ideas generally associated with religious interpretations of human existence. Most readers are intrigued by the thought of being able to have and control OBEs, and see them as a potentially interesting experience, though some smaller number of people taking part in discussions are interested in trying to figure out their nature and function and their possible implications for the understanding of what it means to be fully human. What is an out-of-the-body experience? Not all OBEs occur spontaneously. What are ESP, PK and psi? What is animism? G.
Before Civilization - Ancient Civilizations for Kids Early humans showed another major sign of intelligence about 35,000 years ago. Humans began to draw on the walls of caves—probably other places too, but it has been preserved in caves. Cave paintings often depict hunting scenes. This is some of the first artwork and also an early attempt at written communication. Development of Agriculture The most important development in human history is the development agriculture, which is another word for farming. Corn is a good example of domestication. Humans have lived in Africa longer than anywhere else, but many African societies adopted farming much later than other parts of the world. The soil near rivers is very fertile—or full of plant food and good for growing. Agriculture Brings Changes Farming had other effects on lifestyle and society. The society that farming created forced people to interact in new ways. The world was rapidly changing and people finally had time to settle down and think about the world around them.

Is this the ancestor of all primates? - life - 05 June 2013 (Image: Paul Tafforeau (ESRF) and Xijun Ni (Chinese Academy of Sciences)) Could this tiny animal, with a body just seven centimetres long, be the ancestor of all living primates – including humans? For now, its official classification makes it a tarsier cousin of ours, one step removed on our primate family tree. At 55 million years old, A. achilles (or Archie, as we've taken to calling it at New Scientist) is the oldest primate skeleton ever found, and one of the most primitive. According to its discoverers, Archie is a primitive tarsier – a group of primates closely related to monkeys, apes and humans. That may not be the end of the story, though. Discover Archie's full story, including how it evolved and its relationship to us, in "Our earliest primate cousin discovered in Asia".
