Magnesium May Boost Brainpower

From Live Science:

Mice given extra doses of a new magnesium compound had better working memory, long-term memory and greater learning ability.

Before you go popping heavy doses of magnesium, however, know that much more testing is needed. Though rodent brains work similarly to ours, animal studies do not always predict what will happen in humans.

"If MgT is shown to be safe and effective in humans, these results may have a significant impact on public health," said Guosong Liu, director of the Center for Learning and Memory at Tsinghua University in Beijing, China.

From The Washington Post:

NASA's grand plan to return to the moon, built on President George W. Bush's vision of an ambitious new chapter in space exploration, is about to vanish with hardly a whimper. With the release Monday of President Obama's budget request, NASA will finally get the new administration's marching orders, and there won't be anything in there about flying to the moon.

The budget numbers will show that the administration effectively plans to kill the Constellation program that called for a return to the moon by 2020. The budget, expected to increase slightly over the current $18.7 billion, is also a death knell for the Ares 1 rocket, NASA's planned successor to the space shuttle. The agency has spent billions developing the rocket, which is still years from its first scheduled crew flight.

I, Virus: Why You're Only Half Human

Part of our DNA (Image: Mehau Kulyk/SPL/Getty)

From New Scientist:

WHEN, in 2001, the human genome was sequenced for the first time, we were confronted by several surprises. One was the sheer lack of genes: where we had anticipated perhaps 100,000 there were actually as few as 20,000. A bigger surprise came from analysis of the genetic sequences, which revealed that these genes made up a mere 1.5 per cent of the genome. This is dwarfed by DNA deriving from viruses, which amounts to roughly 9 per cent.

On top of that, huge chunks of the genome are made up of mysterious virus-like entities called retrotransposons, pieces of selfish DNA that appear to serve no function other than to make copies of themselves. These account for no less than 34 per cent of our genome.

Scientists Set For Nuclear Fusion Fuel Switch-On

From The Independent:

A pivotal step in the march towards fusion power, the "Holy Grail" of sustainable clean energy, could be taken this year.

Scientists in the US are preparing for the dramatic moment when the world's most powerful laser unleashes the nuclear force that lights up the Sun and achieves "ignition".

At that moment, 192 laser beams housed in a building the size of three football pitches will focus on a target the size of a peppercorn to trigger a self-sustaining fusion reaction.

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.

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.

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.

When I saw the crater it made me think of him, what he would have thought, what his reaction would have been. Immediately I thought, 'I'm going to look into this more.'"

In 2003, Gaz launched into a six-year-long global project of tracking down and photographing the planet's cosmic scars, beginning with Meteor Crater. The results speak for themselves: haunting, otherworldly images of craters that are familiar, and yet utterly strange.
