Can Full-Body Airport Scanners Harm You?

The scanners are supposed to be the high-tech version of a physical pat-down.

From CNET:

Since explosive materials were sneaked onto a U.S. domestic flight on Christmas Day, full-body scanning machines are far more likely to make their way to security lines at your local airport, even though they might not have detected said materials.

While the Transportation Security Administration already has 40 such devices in place, it just bought 150 to be placed in U.S. airports and says it plans to buy 300 more (they go for $170,000 apiece). On Wednesday, the Netherlands announced that these scanners would be used on passengers for all flights out of Amsterdam to the U.S., and there is talk of scanners in Nigeria as well.

New Exoplanet Hunter Makes First 5 Discoveries

From Wired Science:

The Kepler Space Telescope, a designated planet-hunting satellite, has found its first five planets, among them an odd, massive world only as dense as Styrofoam.

The number of planets now known outside the solar system has risen to more than 400, but none is yet Earth-like enough to harbor life. Right now, Kepler can only detect large planets orbiting close to their stars, which means that these first planets are too hot to hold liquid water, a requirement for life as we know it.

But over the next year, the mission’s scientists will be homing in on ever more life-friendly places.

Precious Metals That Could Save The Planet

The Rare Earth Research Institute is in Baotou City, above,
in the Autonomous Region of Inner Mongolia, China

From The Independent:

Rare earth elements are driving a revolution in low-carbon technology. Cahal Milmo reports on the commodity that has become the new oil.

Baotou was of little interest to the outside world for millennia. When one of the first visitors reached its walls in 1925, it was described as "a little husk of a town in a great hollow shell of mud ramparts". Some 84 years later, this once barren outpost of Inner Mongolia has been transformed into the powerhouse of China's dominance of the market in some of the globe's most sought-after minerals.

Sex And Shopping – It's A Guy Thing

From New Scientist:

PEOPLE have radically diverse responses to the very idea of conspicuous consumption. Some folks consider it blindingly obvious that most economic behaviour is driven by status seeking, social signalling and sexual solicitation. These include most Marxists, marketers, working-class fundamentalists and divorced women. Other folks consider this an outrageously cynical view, and argue that most consumption is for individual pleasure ("utility") and family prosperity ("security"). Those folks include most capitalists, economists, upper-class fundamentalists, and soon-to-be-divorced men.

2009’s Sleepy Sun Finally Woke Up In December

From Wired Science:

2009 will go down as the sun’s third quietest year on record, under-shone only by 1913 and 2008.

Two hundred-sixty of the year’s 365 days (71 percent) were sunspotless. Last year saw 266 sunspotless days, while the sun had no spots on 311 of the days in 1913. It was only a very active December that kept 2009 from falling below last year’s mark.

Sunspot activity waxes and wanes in a roughly 11-year cycle, so hitting solar minima isn’t surprising. But what the numbers underscore is that we spent much of the year still in the midst of the deepest, longest solar minimum in a long time.

Children Reaching Age 3 Without Being Able To Say A Word, Survey Finds

From Times Online:

Children are reaching the age of 3 without being able to say a word, according to a survey that also found boys are almost twice as likely to struggle to learn to speak as girls.

The average age for a baby to speak their first word is 10 to 11 months. However, a significant minority (4 per cent) of parents reported that their child said nothing until they were 3.

Toddlers between the ages of 2 and 3 should be able to use up to 300 words, including adjectives, and be able to link words together, according to I CAN, the children’s communication charity. Late speech development can lead to problems, such as low achievement at school or mental health problems.

From The Independent:

Environmental disruption set to trigger new pandemics, scientists warn.

The world is facing a growing threat from new diseases that are jumping the human-animal species barrier as a result of environmental disruption, global warming and the progressive urbanisation of the planet, scientists have warned.

At least 45 diseases that have passed from animals to humans have been reported to UN agencies in the last two decades, with the number expected to escalate in the coming years.

From The Guardian:

Nasa pictures suggest existence of 12 mile-wide lakes of melted ice on Martian equator 3bn years ago.

Lakes of liquid water existed on Mars at a time when the planet was previously thought to be a frozen desert, new satellite images have shown.

A team of British-led scientists now believes 12 mile-wide lakes of melted ice were dotted around parts of the Martian equator 3bn years ago.

No one had expected to find evidence of a warm, wet climate capable of sustaining surface water on Mars during this period of the planet's history, known as the Hesperian epoch.

ScienceDaily (Jan. 4, 2010) — DNA that is left in the remains of long-dead plants, animals, or humans allows a direct look into the history of evolution. So far, studies of this kind on ancestral members of our own species have been hampered by scientists' inability to distinguish the ancient DNA from modern-day human DNA contamination.

Mankind's Greatest Explorations And Adventures

Corbis

From Time Magazine:

From the Moon to Mount Everest, our list of the greatest leaps and highest climbs in human history.

The crew of Apollo 11 faced risks that were literally out of this world. Engine failure could have left them stranded on the lunar surface or forever lost in space. Solar radiation and re-entry heat could have cooked them alive. A space-suit failure could have suffocated them in the most gruesome way. By today's standards, Apollo 11's technology was primitive — the onboard navigation computer contained only 74 kilobytes of memory, not enough to store a single MP3 music file. But as soon as Neil Armstrong took his first tentative step on the lunar surface, the risks were forgotten. For an all-too-brief moment, everyone on the planet was caught up in the thrill of human achievement, of a millennia-old fantasy come to life. Other lunar explorers would follow, but Apollo 11 was the first to take the giant leap for mankind.
