New Diet Advice: Curb Weekend Calories


From Live Science:

It's no surprise that holiday feasts often bring expanding waistlines, but a new study finds that weekend eating can also be a cause for concern.

Some people chow down more calories on Saturday and Sunday than on a typical weekday, researchers find. The study also showed that people tend to keep track of how much they are consuming on a daily basis, at least in a rough sense. Specifically, if they skimped on breakfast, they would make up for it by gorging at lunch, more or less.

Amanda Kitts is mobbed by four- and five-year-olds as she enters the classroom at the Kiddie Kottage Learning Center near Knoxville, Tennessee. "Hey kids, how're my babies today?" she says, patting shoulders and ruffling hair. Slender and energetic, she has operated this day-care center and two others for almost 20 years. She crouches down to talk to a small girl, putting her hands on her knees.

"The robot arm!" several kids cry.

"You remember this, huh?" says Kitts, holding out her left arm. She turns her hand palm up. There is a soft whirring sound. If you weren't paying close attention, you'd miss it. She bends her elbow, accompanied by more whirring.

The Big Question: Has A Key Breakthrough Been Made In The Search For A Cure For Cancer?


From The Independent:

Why are we asking this now?

British scientists announced yesterday that they have sequenced a "cancer genome" for the first time. It means they have identified all of the many thousands of genetic mistakes that make a tumour cell different from a healthy cell taken from the same cancer patient.

Not all of these mistakes, or DNA mutations, were involved in triggering the cancer, but some of them – the "drivers" – clearly were. Scientists believe it will be possible eventually to identify these driver mutations and find the genetic faults that led to the changes in a healthy human cell that caused it to divide uncontrollably to form a cancerous tumour.

Davy Jones's Lock-Up


From The Economist:

Underwater robots can help study the world’s shipwrecks, a trove of information about the past, more easily and cheaply.

A SHIPWRECK is a catastrophe for those involved, but for historians and archaeologists of future generations it is an opportunity. Wrecks offer glimpses not only of the nautical technology of the past but also of its economy, trade, culture and, sometimes, its warfare. Until recently, though, most of the 3m ships estimated to be lying on the seabed have been out of reach. Underwater archaeology has mainly been the preserve of scuba divers. That has limited the endeavour to waters less than 50 metres deep, excluding 98% of the sea floor from inspection. Even allowing for the tendency of trading vessels to be coasters rather than ocean-going ships, that limits the number of wrecks available for discovery and examination.

The year 1969 was a great time for hippies, a bad year for Beatles fans and an even worse year for UFO enthusiasts. Forty years ago, on Dec. 17th, the U.S. Air Force officially shuttered Project Blue Book, the agency's third and final attempt to investigate extraterrestrial sightings and the country's longest official inquiry into UFOs. From 1952 until 1969, more than 12,000 reports were compiled and either classified as "identified" — explained by astronomical, atmospheric or artificial phenomenon — or "unidentified," which made up just 6% of the accounts. Because of such a meager percentage and an overall drop in sightings, officials axed the program and ended the research. So much for the truth being out there.

Climate Change Is Nature's Way.

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.

Climate Change Does Not Always Lead to Conflict

From Science Daily:

Science Daily (Dec. 17, 2009) — The climate change that took place in Mesopotamia around 2000 BC did not lead to war, but in fact led to the development of a new shared identity. Although increasing drought often leads to competition and conflict, there seems to be no evidence of this in northern Mesopotamia according to Dutch researcher Arne Wossink.

Wossink studied how the farmers and nomads in northern Mesopotamia -- currently the border area between Turkey, Syria and Iraq -- responded to the changes in climate that took place between 3000 and 1600 BC. He expected to find considerable evidence of competition: as food and water became scarcer the natural result could well be conflict. He discovered, however, that the farmers developed much closer bonds with the semi-nomadic cattle farmers.

From The Economist:

Display technology: Readers of electronic books must choose between long battery life or vibrant, living colour. Could they have both?

THE sudden surge in the popularity of e-readers—slate-like devices, such as Amazon’s Kindle, on which electronic books can be read—has been one of the big surprises of 2009. Recessions are often a good time to launch new products, as old certainties are questioned and consumer tastes shift. The iPod made its debut in 2001 in the depths of America’s recession, and e-readers may prove to be a similar success story this time. But today’s e-readers, like that first iPod, are technologically quite simple. Most of them have a monochromatic screen to display text and black-and-white pictures, and none can handle video.

Even so, around 5m e-readers will be sold worldwide in 2009, according to iSuppli, a market-research firm, and a further 12m in 2010. The Kindle is by far the most popular e-reader, but there are many others.

The Publishing Disruption

From The Futurist:

What a unique thing a book is. Made from a tree, it has a hundred or more flexible pages that contain written text, enabling the book to contain a large sum of information in a very small volume. Before paper, clay tablets, sheepskin parchment, and papyrus were all used to store information with far less efficiency. Paper itself was once so rare and valuable that the Emperor of China had guards stationed around his paper possessions.

Before the invention of the printing press, books were written by hand, and few outside of monasteries knew how to read. There were only a few thousand books in all of Europe in the 14th century. Charlemagne himself took great effort to learn how to read, but never managed to learn how to write, which still put him ahead of most kings of the time, who were generally illiterate.

Scientists Crack 'Entire Genetic Code' Of Cancer


From BBC:

Scientists have unlocked the entire genetic code of two of the most common cancers - skin and lung - a move they say could revolutionise cancer care.


Not only will the cancer maps pave the way for blood tests to spot tumours far earlier, they will also yield new drug targets, says the Wellcome Trust team.

Scientists around the globe are now working to catalogue all the genes that go wrong in many types of human cancer.

The UK is looking at breast cancer, Japan at liver and India at mouth.

China is studying stomach cancer, and the US is looking at cancers of the brain, ovary and pancreas.

15% Of Teens 'Sexting' On Cells, Study Says

Who Needs The Grid?

From The Atlantic:

In the boardroom at Bloom Energy, a single picture hangs on the wall: a satellite image of the world at night. Clusters of bright lights mark the industrial centers, and thin white lines trace connecting passageways such as the U.S. Interstate System and the Trans-Siberian Railroad. In between, huge swaths lie in shadow.

Standing almost reverently before the image, K. R. Sridhar, the CEO of Bloom, points to the dark areas—places where electricity isn’t accessible or reliable. “This is my motivation for everything,” he says. To improve the lot of the more than 2 billion people living in those dark areas, he says, you have to get them reliable, affordable energy. And if you don’t want to doom the environment in the process, you have to make that energy very clean.
