It's our good luck one of Earth's many ice ages ended 12,000 years ago.

By HOWARD BLOOM

Climate change activists are right. We are in for walloping shifts in the planet's climate. Catastrophic shifts. But the activists are wrong about the reason. Very wrong. And the prescription for a solution—a $27 trillion solution—is likely to be even more wrong. Why?

Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.

We've been deceived by a stroke of luck. In the two million years during which we climbed from stone-tool wielding Homo erectus with sloping brows to high-foreheaded Homo urbanis, man the inventor of the city, we underwent 60 glaciations, 60 ice ages. And in the 120,000 years since we emerged in our current physiological shape as Homo sapiens, we've lived through 20 sudden global warmings. In most of those, temperatures have shot up by as much as 18 degrees within a mere 20 years.

Scientists find path to fountain of youth (или Жрать надо меньше)

The fountain of youth may exist after all, as a study showed that scientists have discovered means to extend the lifespan of mice and primates.

The key to eternal -- or at least prolonged -- youth lies in genetic manipulation that mimics the health benefits of reducing calorie intake, suggesting that aging and age-related diseases can be treated. Scientists from the Institute of Healthy Ageing at University College London (UCL) extended the lifespan of mice by up to a fifth and reduced the number of age-related diseases affecting the animals after they genetically manipulated them to block production of the S6 Kinase 1 (S6K1) protein.

Scientists have shown since the 1930s that reducing the calorie intake by 30 percent for rats, mice and -- in a more recent finding -- primates can extend their lifespan by 40 percent and have health benefits.

Fossils Shed New Light on Human Past

After 15 years of rumors, researchers made public fossils from a 4.4 million-year-old human forebear they say reveals that our ancestors were more modern than scholars had assumed, widening the evolutionary gulf separating humankind from apes and chimpanzees.

The highlight of the extensive fossil trove was a female skeleton a million years older than the iconic bones of Lucy, the primitive female figure that has long symbolized humankind's beginnings. [...] In fact, so many traits in modern chimps and apes are missing from these early hominids that researchers now question the notion that chimps and apes are a repository of primitive traits once shared by our ancestors. "We all thought the ancestral animal would look more like a chimp," said Yale University anthropologist Andrew Hill. Instead, the new finds show that what seems most ancient about modern chimps and apes -- such as canine fangs, long limbs with hooked fingers for swinging through trees, and hands designed for knuckle-walking -- may actually be more recent developments, the researchers said. In that sense, the human hand today actually may be the more primitive appendage, they said.

"Bread and Circuses is the cancer of democracy, the fatal disease for which there is no cure. Democracy often works beautifully at first. But once a state extends the franchise to every warm body, be he producer or parasite, that day marks the beginning of the end of the state. For when the plebs discover that they can vote themselves bread and circuses without limit and that the productive members of the body politic cannot stop them, they will do so, until the state bleeds to death, or in its weakened condition the state succumbs to an invader--the barbarians enter Rome." - Lazarus Long in To Sail Beyond the Sunset by R.A. HeinleinHere's where we are )

Earlier this year, predictions were rife that the North Pole could melt entirely in 2008. Instead, the Arctic ice saw a substantial recovery. Bill Chapman, a researcher with the UIUC's Arctic Center, tells DailyTech this was due in part to colder temperatures in the region. Chapman says wind patterns have also been weaker this year. Strong winds can slow ice formation as well as forcing ice into warmer waters where it will melt.

Why were predictions so wrong? http://www.dailytech.com/Article.aspx?newsid=13834
