CERN Rap video about the Collider

The scientists behind the world's biggest ever experiment, the Large Hadron Collider, have received death threats. Experts are attempting to recreate the forces which occurred in the immediate aftermath of the Big Bang.

The $10bn machine at CERN near Geneva will be switched on this Wednesday. But sceptics fear it could cause the end of the world. Professor Brian Cox of Manchester University has responded angrily to doomsayers who have predicted an Armageddon.

"Anyone who thinks the LHC will destroy the world is a t***," he said.

Professor Cox added: "There's a kind of magic energy we've not been able to get to, and we know from previous experiments that's where things happen. Now for the first time, we'll be crossing that barrier."

The Large Hadron Collider: End of the world, or God's own particle?

A bewildered Cole Moreton goes in search of the science behind the spin...

Yes, but what is it? That has been many people's reaction to the furore over the Large Hadron Collider, due to be switched on this Wednesday. The biggest, most expensive experiment in history is attracting both scientific hyperbole and hysteria. Some say it will reveal the universe's secrets and lead to the elusive Theory of Everything. A few fear that unleashing unimaginable power beneath the Swiss countryside will result in the end of the world. But how? And what do all these words mean?

Large

Is an understatement. A giant circular tunnel, with several loops, stretches for 27km under the land between France and Switzerland. One of its experimental chambers is bigger than the nave of Westminster Abbey.

Hadron

The name for one of the types of particle that make up an atom. These tiny bits of energy will be propelled by giant magnets around the tunnel circuit at almost the speed of light.

Collide

Is what they will do when they meet other hadrons being beamed in the opposite direction, at the same great speed. The resulting explosion will create 100,000 times more heat than the sun, apparently. Thankfully, it will only happen for a moment, in an area a billion times smaller than a speck of dust.

Cern

Pronounced "sern". The French acronym for the European Organisation for Nuclear Research, which built the £5bn collider. The money came from 20 countries, including Britain, which has played a leading role.

The Big Bang

Is what they are trying to recreate. Or rather what happened a trillionth of a second after the universe was created by an explosion, 13.7 billion years ago. For that tiny moment, it is believed everything was molten plasma. This cooled to create everything we see around us. The hope is that by remaking the moment, in miniature, the scientists will be able to see things that are invisible now.

The God Particle

Big name, very small thing; and the first great discovery they hope to make. It is believed we have only detected a quarter of the particles in everything. We don't, for example, know why things have mass. (To get a feeling for what that is, hit yourself over the head with an inflatable hammer, then a real one. The one that hurts has more mass.) In 1964 Professor Peter Higgs of Edinburgh University predicted an unseen particle that provided mass (its official name is a Higgs boson). The hope is it will be detected for the first time. Other possible revelations include so-called dark matter, which in theory "stretches through space like an invisible skeleton".

The Theory of Everything

The Holy Grail of science. A unifying theory providing one explanation for the forces at work in the natural world, from the nucleus of an atom to the movements of the planets. Sounds like alchemy to non-scientists, but some very respectable minds believe it is possible, and that the collider may show the way.

The End of the World

Some scientists, on the other hand, went to the European Court for Human Rights to try to stop the collider being turned on. They fear it may create a black hole – which would certainly violate our rights by sucking the planet into... well we don't really know. Professor Sir Chris Llewellyn Smith of Cern says: "The chance we produce a black hole is minuscule." Which is not all that reassuring. But he adds: "Even if we do, it can't swallow up the Earth." It would be too small, and disappear in moments. In any case, they will only send the hadrons in one direction this week. The collisions start in October. Until then, at least, we're not all doomed.

*Many people think stem cells are all derived from controversial sources, but this is not so

*See also Skin cells could help with treatment of Alzheimer's in the Guardian

Scientists have made a significant advance in a stem cell technique that could pave the way to finding treatments for dozens of genetic diseases.

The development could help them to find a way of tackling conditions such as Parkinson’s and motor neurone disease.

For the first time a research team has managed to take human skin cells from a patient with a genetic condition and transform them into nerve cells.

It means they will now be able to create limitless numbers of the diseased cells to help them carry out research in the hope of finding a way to treat the illness.

The research has been carried out by an American team.

It's a landscape no human has even seen. And those who live right beside it had no idea it even existed. Deep below the sea, off the north coast of Northern Ireland, a dramatic geological mystery has been discovered. Huge cliffs, vast basins and plateaus, a lake and even rivers have been found. But so far no-one is certain what caused them to end up like this deep under the sea. The discovery was made when the seabed was being surveyed to update old Admiralty charts, drawn up in the mid-1800s.

Artist Ron Dollekamp of Scarborough has created a stunning depiction of the natural universe which creatively mixes elements of space and time to describe the research undertaken by faculty and students associated with the Department of Physics and Astronomy and the Graduate Program in Physics and Astronomy at York University.

The centrepiece of the painting is a fragment of the Earth upon which the Toronto skyline and Lake Ontario are seated. Further emphasizing the Canadian connection, the northern lights hang over the skyline, with the Big Dipper shining through. The Moon and several other planets form a pleasing arc around Toronto, and a blue nebula of interstellar space hangs nearby. The fragment of Earth is seen growing out of the Milky Way galaxy of which it is a constituent. Hurtling towards the galaxy are rays of light, our probe of the universe at large, and a cascade of fundamental particles of nature out of which all matter is composed. The immense scale of the universe is emphasized by the display of another more distant galaxy in the background. The painting not only rivets attention from afar, but many fine details attract closer scrutiny. Even the second "star" in the handle of the Big Dipper is accurately shown to be double.

Astronomy and Astrophysics are represented by the galaxies and their linkages to the particles out of which they formed and to the stars and planets which formed within them.

Atomic and Molecular Physics are represented not only by the stream of particles, which is a mixture of protons and electrons, but also by the northern lights, which are a manifestation of collisions between particles in the solar wind with atoms and molecules in the upper atmosphere.

The essence of Particle Physics is covered by depicting the protons in a manner consistent with the quark model of the atomic nucleus; three "colours" of quarks are confined inside bubbles in such a way that their distinctiveness is most obvious in the centres, but fades away toward the boundaries, as quark confinement models demand.

The Earth's crust and molten core are shown below the city of Toronto, amplifying Earth Physics.

Crystals embedded in the Earth's crust signify Chemical and Condensed Matter Physics, and to a certain extent Optical Physics, as crystals form the heart of lasers.

More subtly, Chemical and Condensed Matter Physics are represented by the blue nebula above the galaxy, which arises from the scattering of starlight off particles of dust floating between the stars.

On a macroscopic scale, the northern lights signify research into both Atmospheric and Space Physics, as their emissions provide a valuable probe of the nature of the upper atmosphere and the interactions of charged particles with the Earth's magnetic field.

Microscopically, the northern lights provide a probe of the structure of atoms and molecules, which are a subject of Optical Physics. The swath of light rays hurtling into the galaxy further illustrates research in this field.

Another focus, Biological Physics, is amplified by the views of the landscape around Toronto and by the incoming streams of particles and light, which are tools used to probe how living things function.

Engineering is highlighted by views of the CN Tower and SkyDome.

Fluid Dynamics, a subject which is fundamental to research in many fields, is depicted by a flow of water out of Lake Ontario into the Milky Way. The connection to the Milky Way completes the cycle of galactic evolution, which is characterized by a continual exchange of matter between star systems and the interstellar medium. The conversion to steam emphasizes the inexorable march of the universe towards a maximal state of randomness.

'When asked by the Pope to demonstrate his artistic skill, 14th century Italian painter Giotto di Bondone supposedly drew a perfect circle freehand and said: "That's more than enough." Now, an international group of engineers and craftsmen has gone him one better and built a pair of nearly perfect spheres that are thought to be the roundest objects in the world.'

Yep! It's round.

American psychologists claim to have found the recipe for a prolific sex life, at least for men: a trio of personality flaws that makes them slightly evil. Surveys of the sex lives and personalities of more than 35,000 people reveal what researchers call a "dark triad" of personality traits that curiously appear to boost men's success with the opposite sex.

Peter Jonason, a psychologist at New Mexico State University, surveyed 200 college students. Those who had more partners, and more short-term relationships, scored higher on the dark triad. They are narcissistic self-obsession, thrill-seeking and callous psychopathy, and Machiavellian exploitation and deceitfulness. "They may represent a successful evolutionary strategy," Jonason told New Scientist. "The strategy seems to have worked. We still have these traits."

Sean Connery as Bond...James Bond

Jonason, who presented his work at the recent Human Behaviour and Evolution Society meeting in Kyoto, Japan, said Ian Fleming's serial womaniser James Bond epitomises the kind of male his survey identified. Instead of investing in long-term relationships, such men may have more children by racking up a large number of lovers.

A second survey of 35,000 people in 57 countries, led by David Schmitt at Bradley University in Illinois, came to a similar conclusion. "It is universal across cultures for high dark triad scorers to be more active in short-term mating," said Schmitt.

Some scientists believe the findings shed light on the enduring question: why do women love bastards? Keller and Jonason suspect the strategy is only successful in communities where the unfortunate combination of personality traits is rare, so women are less wary.
