Archaeology In Jerusalem: Digging Up Trouble

From Time Magazine:

The Jerusalem syndrome is a psychological disorder in which a visit to the holy city triggers delusional and obsessive religious fantasies. In its extreme variety, people wander the lanes of the Old City believing they are biblical characters; John the Baptist, say, or a brawny Samson, sprung back to life.

Archaeologists in the Holy Land like to joke that their profession is vulnerable to a milder form of the syndrome. When scientists find a cracked, oversize skull in the Valley of Elah, it can be hard to resist the thought that it might have belonged to Goliath, or to imagine, while excavating the cellars of a Byzantine church, that the discovery of a few wooden splinters might be part of the cross on which Christ died. This milder malady is nothing new. In the mid-19th century, British explorers who came to Jerusalem with a shovel in one hand and a Bible in the other used the holy book as a sort of treasure map in the search for proof of Christianity's origins.

From Science Daily:

Science Daily (Jan. 30, 2010) — A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion -- the process that generates the sun's prodigious output of energy.

Fusion has been a cherished goal of physicists and energy researchers for more than 50 years. That's because it offers the possibility of nearly endless supplies of energy with no carbon emissions and far less radioactive waste than that produced by today's nuclear plants, which are based on fission, the splitting of atoms (the opposite of fusion, which involves fusing two atoms together). But developing a fusion reactor that produces a net output of energy has proved to be more challenging than initially thought.

How Much Sleep Do I Need?


From Live Science/Tech Media:

Scientists can't say exactly how much sleep each person needs, but there are some guidelines. And you should know that serious lack of sleep — less than six or seven hours a night — has been associated with increased risks of high blood pressure, hypertension, obesity, diabetes and cancer.

But much about sleep's role in health, and the how much sleep each person needs, remains a mystery. Some studies have suggested that older people need less sleep. Research reported in the journal Current Biology in 2008 found that when asked to stay in bed for 16 hours in the dark each day for several days, younger people participants slept 9 hours on average while older people got 7.5 hours of shut-eye.

Kindle vs. iPad: It's Not Zero Sum


Watch CBS News Videos Online

From CBS News:

Amazon provided its most detailed figures on sales of its Kindle, putting the units in the marketplace in the millions. The big questions: How long can Amazon defend its turf vs. Apple's iPad? And will consumers consider the iPad and Kindle to be two completely different devices with different use cases?

The e-commerce giant on Thursday reported another strong quarter, but the highlight of the financials and the call may have been at least some detail on Kindle sales. Due to an accounting change where Amazon can recognize more Kindle revenue up-front, the company had to offer a little more detail than usual about sales. Granted, Amazon didn't offer much, but CEO Jeff Bezos said in a statement:

Fun Inc: Why Games are the 21st Century's Most Serious Business -- Book Review

A scene from Grand Theft Auto: Liberty City Stories for Technology (2005).

From The Guardian:

Here is a compelling defence of the much maligned but fantastically successful computer game.

It's a curious fact that, though videogames are now the world's largest entertainment industry in financial terms, they are rarely reviewed in the mainstream media. There's a thriving world of academic discussion about gaming but Newsnight Review or The Culture Show hardly ever feature them, and newspapers give them far less coverage than those other pointless-but-fun games played on a field with a ball. It's curious too that, despite their financial success, it's so easy to find people who've not only never played a videogame but who feel viscerally that they're a pernicious waste of time. If games are an artform, arts journalism is mostly uninterested. If they're a sport, they're not one we treat as admirable. The sale of games is increasing by 20% a year but, outside the gaming press, we're not really talking about them.

Network Theory: A Key to Unraveling How Nature Works

From Environment 360:

Ecologists who want to save the world’s biodiversity could learn a lot from Kevin Bacon.

One evening in 1994, three college students in Pennsylvania were watching Bacon in the eminently forgettable basketball movie The Air Up There. They started thinking about all the movies Bacon had starred in, and all the actors he had worked with, and all the actors those actors had worked with. The students came up with a game they called Six Degrees of Kevin Bacon, counting the steps from Bacon to any actor in Hollywood. In general, it takes remarkably few steps to reach him. Even Charlie Chaplin, who made most of his movies decades before Bacon was born, was only three steps away. (Chaplin starred with Barry Norton in Monsieur Verdoux, Norton starred with Robert Wagner in What Price Glory, and Wagner and Bacon worked together in Wild Things.)

From Science Daily:

Science Daily (Jan. 29, 2010) — The first experiments at Lawrence Livermore National Laboratory's National Ignition Facility (NIF) have demonstrated a unique physics effect that bodes well for NIF's success in generating a self-sustaining nuclear fusion reaction.

In inertial confinement fusion (ICF) experiments on NIF, the energy of 192 powerful laser beams is fired into a pencil-eraser-sized cylinder called a hohlraum, which contains a tiny spherical target filled with deuterium and tritium, two isotopes of hydrogen. Rocket-like compression of the fuel capsule forces the hydrogen nuclei to combine, or fuse, releasing many times more energy than the laser energy that was required to spark the reaction. Fusion energy is what powers the sun and stars.

Advances In Minefield Technology

The Virtual Minefield Metal Storm

From Popular Science:

From a tactical military standpoint, land mines have a certain set-it-and-forget-it appeal; you blanket an area in munitions and move on, secure in the fact that if the enemy tries to cross that terrain they'll find an automated resistance waiting for them. But we all know that land mines are also one of modern warfare's most indiscriminate and devastating developments, with the capacity to kill and maim innocent people even decades after hostilities have ceased. To remedy this problem, arms maker Metal Storm has developed a virtual minefield that delivers the tactical advantage of land mines without blanketing areas with dangerous ordnance that could be left behind.

From The Guardian:

There are now dozens of websites to help budding authors to publish their novels, poems and pictures and, perhaps, even make a profit from it.

If you want to realise a dream by publishing your own book, there are lots of companies willing to extract upwards of $500 from you for the privilege. At the other end of the spectrum is Amazon's digital text platform, which allows you to upload your pre-prepared files to its Kindle reader and then set your own price.

Superfast Bullet Trains Are Finally Coming To The U.S.


From Wired Science:

Believe it: Bullet trains are coming. After decades of false starts, planners are finally beginning to make headway on what could become the largest, most complicated infrastructure project ever attempted in the US. The Obama administration got on board with an $8 billion infusion, and more cash is likely en route from Congress. It’s enough for Florida and Texas to dust off some previously abandoned plans and for urban clusters in the Northeast and Midwest to pursue some long-overdue upgrades. The nation’s test bed will almost certainly be California, which already has voter-approved funding and planning under way. But getting up to speed requires more than just seed money. For trains to beat planes and automobiles, the hardware needs to really fly. Officials are pushing to deploy state-of-the-art rail rockets. Next stop: the future.

Water Vapour Caused One-Third Of Global Warming In 1990s, Study Reveals

A 10% drop in water vapour, 10 miles up has had an effect on global warming over the last 10 years, scientists say. Photograph: Getty

From The Guardian:

Experts say their research does not undermine the scientific consensus on man-made climate change, but call for 'closer examination' of the way computer models consider water vapour.

Scientists have underestimated the role that water vapour plays in determining global temperature changes, according to a new study that could fuel further attacks on the science of climate change.

The research, led by one of the world's top climate scientists, suggests that almost one-third of the global warming recorded during the 1990s was due to an increase in water vapour in the high atmosphere, not human emissions of greenhouse gases. A subsequent decline in water vapour after 2000 could explain a recent slowdown in global temperature rise, the scientists add.

A puzzling drop in the amount of water vapour high in the Earth's atmosphere is now on the list of possible culprits causing average global temperatures to flatten out over the past decade, despite ever-increasing greenhouse-gas emissions.

Although the decade spanning 2000 to 2009 ranks as the warmest on record, average temperatures largely levelled off following two decades of rapid increases. Researchers have previously eyed everything from the Sun and oceans to random variability in order to explain the pause, which sceptics have claimed shows that climate models are unreliable.

From The New York Daily News:

A group of scientists have a plan to save the planet - volcanoes!

Simulated volcanoes, to be precise.

The idea, detailed by a trio of environmental scientists in an editorial for the journal, Nature, would potentially be cheaper than forcing industries to cut carbon emissions.

"Many scientists have argued against research on solar radiation management," write David Keith of the University of Calgary in Canada, Edward Parson of the University of Michigan and Granger Morgan of Carnegie Mellon University.

From Times Online:

Using biofuel in vehicles may be accelerating the destruction of rainforest and resulting in higher greenhouse gas emissions than burning pure petrol and diesel, a watchdog said yesterday.

The Renewable Fuels Agency also warned that pump prices could rise in April because of the Government’s policy of requiring fuel companies to add biofuel to petrol and diesel. More than 1.3 million hectares of land — twice the area of Devon — was used to grow the 2.7 per cent of Britain’s transport fuel that came from crops last year.

From The New York Times:

SAN FRANCISCO — Apple has generated a lot of chatter with its new iPad tablet. But it may not be quite the conversation it wanted.

Many women are saying the name evokes awkward associations with feminine hygiene products. People from Boston to Ireland are complaining that “iPad,” in their regional brogue, sounds almost indistinguishable from “iPod,” Apple’s music player. The problem may be worse outside the United States; Japanese does not even have a sound for the “a” in iPad.

Learning To Forget

In the 2004 movie Eternal Sunshine of the Spotless Mind Jim Carrey has his memory erased to forget a painful relationship. Scientists are a long way off performing this type of procedure in people, but studies suggest that it is, indeed, possible. Credit: Focus Features

From Cosmos:

Painful memories that cause distress could soon be a thing of the past. Recent studies suggest memories can be manipulated, edited - and even deleted.

JASON NICOLL IS TORMENTED by the past. In 1994, when he was 21 years old, he was deployed with the Australian Defence Force to serve six months in Rwanda. This was at the height of the genocide.

"I saw dead bodies, people who'd stood on land mines, people who'd been shot or hacked up with machetes. Once, I carried a young girl, about eight or nine years old, who'd been shot in the chest.
