POPSThe Girls 'Sexualised' At Age Of Five Researcher Dr Eileen Zurbriggen said that girls as young at four are at risk. "The consequences of the sexualisation of girls in media today are very real and are likely to be a negative influence on girls' healthy development," she said. "As a society, we need to replace all these sexualised images with ones showing girls in positive settings. "The goal should be to deliver messages to all adolescents - boy and girls - that lead to healthy sexual development." Michele Elliot, of child protection charity Kidscape, said: "Bratz dolls are little sexualised creatures which give the wrong message to kids. "Let them be kids. We have got children of 12, 13 and 14 who are ashamed that they haven't had sex yet. They think sex is the be all and end all." A spokesman for Bratz said that children see the dolls as being pretty rather than sexy.

POPSThe Teen Brain Human and animal studies, Jensen and Urion note, have shown that the brain grows and changes continually in young people—and that it is only about 80 percent developed in adolescents. The largest part, the cortex, is divided into lobes that mature from back to front. The last section to connect is the frontal lobe, responsible for cognitive processes such as reasoning, planning, and judgment. Normally this mental merger is not completed until somewhere between ages 25 and 30—much later than these two neurologists were taught in medical school. There are also gender differences in brain development. As Urion and Jensen explain, the part of our brain that processes information expands during childhood and then begins to thin, peaking in girls at roughly 12 to 14 years old and in boys about two years later. This suggests that girls and boys may be ready to absorb challenging material at different stages, and that schools may be missing opportunities to reach them.

POPSThinking the way animals do
Temple Grandin Ph.D. is an assistant professor of animal behaviour at Colorado State Uni. She suffers from a form of autism, and describes the way she thinks as thinking in pictures. This has helped her understand the way Animals think, with direct association, rather than a logical process. A significant statement which can apply to most people, is the fact that originally as far as she was aware everybody thought the same way. Until she asked people and found this was not the case. She describes a radio station person who said she had no pictures, in her mind, but thought in terms of emotions or words. I'm sure I can understand my dogs. They seem to think in a manner that is simple, and straightforward, it can just be a matter of associating cues with behavior, and remembering Pavlov. I think in Pictures and sounds. There is music I can 'hear' in my mind that not only has the same 'quality' as the original, but there is a remarkable capacity to edit. Perhaps something like Auti

POPSZebra's Stripes, Butterfly's Wings: How Do Biological Patterns Emerge? Previous work identified a specific signal necessary for getting these fly egg cells to move; the problem is that this signal is “graded.” Like drops of ink spreading out on wet paper, this signal travels in between surrounding cells, gradually fading away as it moves outwards. But clear lines are required for pattern formation — there is no grey area between a zebra’s black and white stripes, between heart and liver cells and, in this case, between migrating cells and those that stay put. How are graded signals converted to a clear move or stay signal? By examining flies containing mutations in different genes, the researchers discovered that one gene in particular, called apontic, is important for converting a graded signal.

POPS"World needs a vacation from USA" He called for immediate technology transfer from the West to the Third World, to allow development based on clean technology — stressing the need to “reject intellectual property rights”. funds should not be distributed through the World Bank, which was trying to regain legitimacy by portraying itself as a “climate bank” while continuing to push fossil-fuel-driven development. Confronting global poverty and climate change means confronting US power. “I don’t think the world needs US leadership”, he said. “They should be more humble.” Whether the US achieves its goals “is where we, as civil society come in”, Bello said, suggesting that, by making intervention costly for the US, civil society could encourage a “new US isolationism”. The struggle is, he stressed, global. “The world needs a vacation from the messaianism of the US … A few decades of a self-absorbed US would be very good for the world.”

POPSNASA Needs to Take Space Sex Seriously The fact remains however, that we are naive of the effects of sex in space, let alone if it is even a pleasurable experience. The mechanics of "human docking procedures" (as described by tests carried out by the Russian space agency) are a lot more complicated when in zero gravity. There are also huge ethical questions hanging over possible pregnancies in space. Zero-G tests on rat embryos produced decreased skeletal and brain development, the effects on a human embryo will remain a mystery. The fact remains that NASA continues to cut back biological research in favor of future Moon missions, so much about human sexuality in space will remain a mystery.

POPSChimpanzees brought up with love develop faster than babies.. "They were also more advanced intellectually than chimpanzees reared with standard institutionalized care." Giving birth is so 'natural' yet taking care of them, raising them to be mature, independent and intelligent both emotionally and mentally is not obvious. And though almost everyone would agree with what i have just written it stops here, because no-one dares to tackle the 'issue' of what is perceived as a 'natural' right (i.e. everyone can have babies, whenever she wishes, how many he wants).

POPSOne hundred and fifty years ago on Aug. 27 “When the discovery happened, the few people who were there and not involved in the war, went around and bought all the property they could and had outside investors come in,” Black said. “But the real heyday of the development happened from 1864-1870. It’s that 11-year period when the little river valley was the world’s leading supplier of oil. ”The “little river valley” in western Pennsylvania earned the nickname Petrolia. “I would see this as less of an anniversary to note for celebration and more of an anniversary to note how far we’ve come and the serious moment that we’re at right now,” said Brian Black, an energy historian at Pennsylvania State University and author of the book Petrolia. “Energy transitions happen and I argue that we’re in one right now and that we need to aggressively look to the future to what’s going to happen after petroleum.”

POPSThe Daughter Deficit In a family that expects to have seven children, the birth of a girl is a disappointment; in a family that anticipates only two or three children, it is a tragedy. Thus development can worsen, not improve, traditional discrimination. This can happen in other ways too. With the access it brings to cutting-edge technology, development can also offer more sophisticated and easier options for exercising old-fashioned prejudice. In China and in the north and west of India, for instance, the spread of ultrasound technology, which can inform parents of the sex of their fetus, has turned a pool of missing girls into an ocean. The birth of girls has long been avoided through infanticide, which is still practiced often in China. But there are even more couples who would abort a pregnancy than would kill a newborn.Ultrasound has been advertised in India as “pay 5,000 rupees today and save 500,000 rupees tomorrow.”

POPSWhat percent of US budget goes to foreign aid? Most Americans drastically over-estimate it. Despite laudable recent increases in US giving to poverty, US aid as a percent of personal income is second to last among wealthy nations; most of that doesn't go to the poorest countries. We give about 25 cents per American per day ] day in foreign aid; with private giving, another dime. It's a lot, because there are a lot of us. But it's far behind the level of sacrifice made by people in most developed nations.

POPSThe Big Question: Do electronic books threaten the future of traditional publishing? A tipping point for e-books could come when content starts to be made available on the next-generation of mobile phones. the author Toby Young says: "The great thing about electronic books is that in the long run they will benefit writers, creating an easier way to enable first-time authors to get their work in front of the public. That will be a revolutionary change." Is this the end of the book as we know it? Yes...

POPSInternet Access Without Electricity, Connectivity or Phone Services. No Matter Where You Are. what open source collaboration can do.. The terminals includes access to web browsing, email, voip, office, multimedia, software development and web development tools as well as 15,000 other applications. Wifi coverage spans a 2-mile radius, with no fuel costs, no polluting emissions and a long lifespan of up to 20 years with proper maintenance. The entire system, in fact, operates on about the same amount of power as a 100-watt light bulb, GNUveau says.

POPSThe Pope is Absolutely Right Publicity from anywhere on this is good. It rarely makes the headlines but deep in the heart of the financial system is this legalised fraud whereby greedy rich people (and, of course, not all rich people are greedy) evade taxes, enhance profits, and destablise the global economy. In the UK alone it is estimated that individuals and companies legally syphon off £20 billion annually.

POPSSupermarkets Throwing Away 2 Million Tons Of Food A Year We visited a dozen stores over several nights last week to check what was being thrown away and discovered hundreds of pounds worth of food dumped. At a Sainsbury’s superstore next to the Dome in Greenwich, South East London – the chain’s flagship “environmentally-friendly” shop with its own wind turbines – staff said it was standard practice to throw away food before its sell-by date. And they’re not even allowed to take it home. One said: “Someone just stands there and throws it into the skip. We wish we could buy it – but we’re not allowed.” Pointing to meat on the “reduced” shelf, he added: “Come midnight, anything that hasn’t been sold will get taken off the shelf... if it’s out of date it will be logged on the computer, put against our losses, then in the skip.” Four-pint bottles of milk with nine days still to run had been thrown out, along with nine cans of cola with a date stamp of April 2009.
