Pluto's Orbit
This is a drawing showing the orbit of Pluto and the outer planets. It shows the planets on June 1, 1997. In the larger version at least, you can see dots next to the names indicating planet position. In 1997, Pluto was closer to the Sun than Neptune. Pluto has the most eccentric orbit of all the planets in the solar system. That means that Pluto's orbit draws within the orbit of Neptune, as can be seen in this drawing, making Pluto the 8th planet rather than the 9th planet for roughly 20 years at a time. It takes 248 years for Pluto to complete its orbit. In addition to its peculiar orbit, Pluto and its moon Charon are locked together as they orbit each other, so that the same side of each body always faces the other.

Eight planets
Mike Brown On August 24th 2006 the word "planet" was given its first-ever scientific definition by a vote of the International Astronomical Union. With the raising of a few yellow cards in Prague, Pluto was demoted from full-fledged planet to "dwarf planet." Eris, originally called 2003 UB313, sometimes called Xena, sometimes called the "10th planet," which in many ways precipitated this final debate, becomes the largest known dwarf planet. What is a dwarf planet? When the final vote on the definition of "planet" was made, and the eight dominant bodies in the solar system were declared (quite rationally) a class separate from the others, a new class of objects was defined. How many dwarf planets are there? There are two ways to look at this question. Reality, however, does not pay much attention to official lists kept by the IAU or by anyone else. So how many dwarf planets are there? How many objects larger than 400 km are there in the Kuiper belt? Who has discovered dwarf planets?

Determined to be different: what we do changes the wiring of our genes
The human genome provides penetrating and unexpected insights into human individual and collective history. Among them is the counterintuitive idea that genes are at the mercy of experience – that what we do in our lives affects which genes are switched on and off. A stressful experience, for example, can make you more vulnerable to infection, because stress hormones indirectly alter the switches that control the expression of genes. So, far from genes being the cause of how we act, the new understanding sees them as just as much a consequence of how we act. On a much longer, evolutionary timescale, the same reversal of causation is necessary. We now know that many genetic changes in human beings are driven by cultural ones, at least as much as the other way round. For example, the ability to digest lactose as adults spread among Africans and Europeans because of dairy farming, rather than vice versa. Blue eyes may be a consequence of the invention of agriculture.

Gut Bacteria Know Secrets About Your Future : Krulwich Wonders…
You have a hundred trillion of these guys in you right now. Before you were born, you had hardly any. Barcroft/Fame Pictures Back then, you were floating in amniotic fluid, protected, sanitized. Bacteria kept their distance. Then came your birthday, and all of a sudden, you were invaded. Paula Bronstein/Getty Images Right now, in your mouth, in your gut, on your skin, you are carrying about 10 times more bacteria cells than human cells. "We are, in essence, only 10 percent human," Dr. Mostly Microbe What are bacteria doing in you? They look, yes, a little alien. Now comes the big (and double) surprise. First (I wrote about this a few years ago), scientists discovered that people around the world can have different communities of bacteria in our intestines. I, for example, might have a lot of bacteria in me that are great at digesting oats. I gain weight. So why do different people attract different bacteria as they grow up? Scientists assumed it must be cultural. iStockphoto.com
