Time magazine says there is a "scientific debate" going on about whether animals commit suicide. What a load of poppycock! The Mind Hacks blog links to buy wow gold Time's article, at least pointing out that: "The piece doesn't answer the question of whether animals can end it all, but is a fascinating look at how the idea that they can has gone in and out of fashion." In case there's any confusion about whether animals can top themselves: they can't. Animals would first need to be shown to have a well-developed sense of self before we could even consider the idea wow gold that they might decide to voluntarily end their lives. There is some evidence in a few animals for this, notably great apes, dolphins and elephants. Some corvids - birds in the family that includes crows and rooks - might be able to "know themselves" too. Some robots have passed the mirror test, but dogs, horses and cats? There's no evidence that these animals have a sense of self. The Time story comes from a paper discussing the history of the idea, from Aristotle to Victorian times. How this discussion of dusty anecdote becomes a "scientific debate" is unclear, to say the least. But a quick web search reveals the idea is strongly ingrained. A bridge in Scotland is famous for regular apparent cases of dog suicide. Our readiness to believe that our pets might top themselves in grief after we die clearly says more about human vanity than animal behavior. As a sensible member of the Scottish Society for the Prevention of Cruelty to Animals told The Times: "Animals do not commit suicide". There is one animal that if we stretch the point, could be said to "commit suicide": the Japanese foliage spider. Females allow their young to consume their own body. | ||

In china, with the enforcement of the birth control policy, most parents have only one child. The parents and grandparents have shown cheap wow gold too much love to their only child; the number of spoiled children has increased in China. Consequently, how to bring up the child becomes a serious problem to many young parents. The only child has shown complete dependence on the parents. Many five to seven-year-olds still hang on their patents in almost every aspect of life, from buttoning cloths to going to the toilet. These children have never learnt to buy wow gold instant delivery do elementary household chores. Even worse, the only children tend to be ill mannered and self-centered. They often fight over something instead of cooperating together. Parents give them calculators, turn on the television and leave the teaching to teachers. Some parents even offer material incentives to reluctant children to lure them to learn and to do something. They are a generation of kids who have never been hurt or hungry. They have learned somebody will always do things for them. The key to solving the problem of spoiled children lies in correctly educating both children and adult. In my opinion, hard life is good for children. Parents should be used to saying no to the kid, and let a child do hard work. Working hard will give him an opportunity to taste the bitterness quickly. Besides, hard work may enable him to cherish the fruit of the others’ labor. Human society is full of tests and trials. Flowers from a greenhouse can never withstand a storm. Children who live luxuriously and comfortably can never become somebody in the future. Besides, to reduce the chance of spoiled children, parents and society must work together. Meanwhile, both primary and nursery school should step up their efforts in training children. | ||

Our brains consider many factors when forming first impressions. In general, we make associations between people and positive feelings. For example, the authors of an October 2008 study published in the journal Science found that people who held a hot cup of coffee for ten to twenty-five seconds before meeting someone rated their first impressions of the stranger more positively than those who held iced coffee. The subjects literally “warmed” to the people they were meeting because they associated the strangers with the comforting feeling of gentle heat. Though the authors of this study did not speculate on the cause for the connection, evolutionary biology may be at play here. When we are happy and secure, we have less reason to feel threatened by strangers and are less likely to want to distance ourselves from them as a defense mechanism. In other words, if I’m not in danger of being hungry or cold, I don’t have to worry as much that you’ll steal the wood I need to make fire and I can be nice to you instead. In addition to concrete feelings like warmth, our brains process a variety of sensations when we meet someone for the first time. Facial expressions are key—a smile versus a frown makes us register to others as a friend, not a foe—as are all the factors that affect our general levels of comfort and senses of security. Color and proportion matter because our brains register incongruities of any kind as jarring. If someone with a warm complexion is wearing cool colors, for example, or a set of clothes that doesn’t fit them well, our animal brains will tell us that something is amiss and dangerous, and we will form a negative impression associated with that | ||

Scientists are puzzling over a surprising increase in stomach cancer in young white adults, while rates in all other American adults have declined. Chances for developing stomach cancer are still very low in young adults but the incidence among 25 to 39 year old whites nonetheless climbed by almost 70 percent in the past three decades, a study found. National Cancer Institute researchers and colleagues examined new cases from 1977 to 2006 of cancer in the lower stomach, which can be caused by chronic infection with a common bacteria called H. pylori. It also causes stomach ulcers. RuneScape Gold Overall, there were 39,003 cases detected in a surveillance program that covers about one-fourth of the U.S. population. These included only 734 white young adults, but their incidence rate climbed from .54 per 200,000 to about 1 per 200,000. Among white adults aged 25 to age 84, the rate declined from almost 12 per 200,000 to 8 per 200,000; among black adults it declined from about 27 per 200,000 to 19 per 200,000. Rates also declined for other races, which weren't specified. RS2 Gold Dr. Jaffer Ajani, a digestive cancer specialist at the University of Texas M.D. Anderson Cancer Center in Houston, said the increase in young white adults is surprising but not alarming. Ajani, who was not involved in the research, said it could be a statistical blip but that it needs to be investigated. The study appears in Wednesday's Journal of the American Medical Association. It focused on lower stomach cancer, not cancer of the upper stomach, which has been linked with gastric reflux. Together, these cancers are the fourth most common type of cancer worldwide. In U.S. men, stomach cancer is among the top 10 most common cancers in blacks, Asian-Americans, Hispanics and American Indians. It's also among the most common cancers in Asian-American women. Lower stomach cancer has been linked with diets high in salt and salt-preserved foods, and low in fresh fruits and vegetables; its incidence historically has been higher in Asia and other countries where this type of food preservation is more common. But stomach cancer rates have been declining in many countries because of improved food preservation and better hygiene, which decreases risks for H. pylori infection, so the overall U.S. decline was expected, said Dr. Charles Rabkin of the National Cancer Institute, the study's lead author. However, the researchers noted that salt intake has increased among Americans of all ages, and said they will be investigating whether changes in eating habits explain the rise in young adults. H. pylori prevalence might have increased in young adults, or there may be some other unknown bacteria that could play a role, although those theories remain unproven, Rabkin said. | ||

Sun dogs, or parhelia, are little back-up suns that appear on either side of the sun. They are the Pips to the sun's Gladys, the Lion and the Witch to the sun's Wardrobe, and they look way cooler than rainbows. What is it that makes these parhelia possible? Only the most badass shape in the whole world: the hexagon. It's the geometric shape that rhymes with sex and means ‘an evil spell.' It's balanced, edgy. It's got an angle on everything. It's what the pentagon would have been if the government hadn't been too cheap to add that last wall. There's nothing that the hexagon can't do. When it gets cold enough, hexagons fall from the sky. Literally. When water freezes it forms hexagonal crystals. Sometimes the crystals are long, pencil-shaped objects, but much of the time they are flat disks. When they fall, the flat side turns parallel to the earth, due to Io9's old friend, the Bernoulli Effect. When the disk tilts so that an edge pushes out, the air around it rushes past faster. This creates a low pressure zone and pulls the crystal's edges out harder, until it is flat-side-down. RuneScape Gold This leaves the hexagonal shape of the crystal open to exploitation by miscreant sun beams. Most of us know that certain substances, including ice, can bend light. It's difficult to understand, though, how this would make duplicate suns appear. RS2 Gold Picture someone looking at a regular sunset. It's pretty easy to understand the course of the light. The sun gives off photons in all directions, and some of them travel in a straight line until they hit the person's eyeball, allowing them to see the image of the sun. Now picture two other people on either side of the original person, about a quarter mile away. They would also get face-full’s of photons, allowing them to see the sun.

Google offering $100,000 cash bonuses is so last summer. Now it's apparently offering seven-figure stock payouts to keep engineers from defecting. Last week it was $3.5 million. This week, All Things D reports that one engineer ended a bidding war by taking a $6 million stock grant. Runescape2 Gold We've seen talent wars like this before. Let’s look back something happened in the history Microsoft was sued back in 1997 for poaching employees from database company Borland. Google returned the favor last decade, causing Steve Ballmer throw a chair across the room. RS gold Now, Google is trying its hardest not to end up on the losing end as the cycle repeats itself. The trouble with paying these kinds of retention bonuses is that once you start, it's very hard to stop. They're basically giving employees an extra incentive to sniff around Facebook or another pre-IPO startup so they can get a job offer to dangle back in front of their managers. A lot of employees are always going to be motivated by money, and with the stock no longer doubling every year, Google's in a tough spot. But the company may need to take a hard look at other cultural factors as well. We hear more and more tales of new committees, intra-group politicking, and attitude problems toward new employees, particularly those who come in through acquisitions. Facebook is still mostly small enough and agile enough to avoid those problems.

What Apple might introduce in the second-generation iPad. Before I begin, allow me to turn off my current iPad. I don't want it watching and getting any more distressed than it already is. Resolution: Runescape Gold It's a lock that Apple will take the 1024x768 resolution up a few notches and possibly add the Retina Display to its tablet device. First introduced on the iPhone 4 last year, this high-resolution technology takes the display where no display has gone before, beyond the limits of human visual perception—at least that's what Apple tells us. The reality is that it makes even the densest Web site a breeze to read on the iPhone 4 screen. Imagine what it will do to the iPad's more generous screen real estate. Camera[s]: When I met with HP earlier this month to get up-close and personal with the new TouchPad (it took all night to convince my iPad that me and the TouchPad are, for now, just friends), HP said they only put one front-facing camera on the device because they could not imagine anyone holding up their 9.7-inch device and filming with it. I cannot tell you how many times I wished my iPad had cameras on the front and back. Of course I'd be happy to hold it up and film with it. I fully expect Apple to put cameras on both sides of the iPad 2. Faster: Runescape gp Apple doesn't talk very much about the raw power behind its home-grown A4 chip, but I'm sure Apple wants to crank it up a bit. In fact, with a much higher-screen resolutions, I don't think Apple has any choice. All the subsystem specs should go up. In fact, I would not be surprised if Apple drops the lower storage option (16 GB) on the iPad 2 and adds a new higher-end one: 128 GB. More Stable OS: Here's a dirty little secret about the iPad: It does crash. Okay, not so much the iPad, but the apps that run on it. I think Apple will introduce an updated OS to better navigate app faults and more gracefully handle crash-prone apps. The latest OS will also support 20(!) fingers of touch and add more nuance to the multitasking support so you can see what's going on under each of those app icons.
