Contents
The new academic year brings with it the resurrection of all that is student life – of course this will mean different things for each of us, but for many it will probably consist of an overwhelming sense of trying to cram in as many things as possible in to each 24 hour period. So students, when you are next sitting at your desk cramming for an exam

in to the early hours of the morning, trying to fit a gym session in before lectures or alternatively deciding between doing a shift at work or going to fab, you may be forgiven for wishing you were a Phreatichthys andruzzii. This cavefish that has just been discovered living in the deep caves under the Somali desert has been isolated in complete darkness for almost two million years, evolving without a day-night cycle. The result of this is their circadian rhythm has evolved in response to this lack of light and consequently their body clock has shifted from the typical 24 hours to 47 hours – meaning each of their ‘days’ is almost twice as long as ours! If only evolution would be so kind to us…

Biodiversity in Plants: Why Should I Care? Conservation: ask the average person what this word means to them, and they might think of images of cute tigers, or a lonely polar bear balanced precariously on an ice floe. Indeed these are species at risk of extinction, but behind these charismatic icons, a greater and more pernicious danger lies: the staggering rate of loss of plant biodiversity.
Current rates of plant extinction have been estimated at 100-1000 times the natural background extinction rate. Plants are vitally important. They provide food, medicines, ornaments, habitats, raw materials, fuel, carbon sinks and myriads of other amenities to humans and other life forms. They produce oxygen through photosynthesis: 20% of the world’s oxygen is estimated to come from the Amazon rainforest alone. Rice is a staple food for over half the world’s population, and grains of all kinds are now the basis of the global human diet, feeding over six billion people. Many medicines, including aspirin, morphine, digitalis, quinine and the anticancer drugs vincristine and taxol all originated from plants, and it is estimated that 25-50% of medicines approved for use in the USA contain either plant-derived active ingredients, or synthetic or
modified versions of compounds originally identified in plants. When reminded of the huge importance of plants as a natural resource, it is worrying that current rates of plant extinction have been estimated at 100-1000 times the natural background extinction rate. The Sampled Red List Index, a report published by Kew and the International Union for the Conservation of Nature (IUCN) in September this year, described one out of every five known species of plant as threatened by extinction.
yet this area of tropical rainforest is being lost approximately every 17 seconds.
Plants are essentially the bottom of a house of cards: remove them and everything else collapses. For a top predator such as a tiger or bear to go extinct would be a shame, to be sure. But it would not be as catastrophic for biodiversity and the ecosystem as a whole as the extinction of the 20% of plants that are currently threatened would be. Plants are relied upon by so many other species, from bacteria and fungi to herbivores large and small, and, The crisis deepens when you ultimately, humans.

Are We On The Edge Of A Mobile Phone Crunch? We all have at least once experienced a break-down in our mobile network, especially in big crowds during sporting events or gigs. People living in big cities like London and New York face this problem increasingly more often. And it threatens to get worse. When the 3G network was rolled out a decade ago, cellphone congestion seemed almost unreasonable. Then Apple launched the iPhone and have sold 50 million devices since. Think of the mobile network as a motorway that is built for the BlackBerry of Mercedes and the iPhone of BMW. Hence it wasn’t especially crowded 10 years ago.

more common. But this is not the extent of what malevolent hackers could potentially do. It has been identified that many computer applications running vital national services and financial computer systems are open to attack by competent hackers. The risks posed by the cyber savvy harbingers of doom are not taken lightly, with the formation of the US Cyber Command in June 2010 with the UK soon to follow with a similar system; global governments are taking the situation very seriously. Both the UK and India have confirmed plans to set up online tracking systems designed to sniff out criminal and dangerous behaviour on the Internet. Although cyber attacks could potentially wreak havoc on this country, those in the know suggest that most of our enemies do not possess the core skills required to hack such sophisticated systems. With the global eye firmly on the information security sector, we can be sure that both British and Global security agencies will have many teams of cyber do-gooders watching our backs, protecting us from the dastardly misdoings of the dark side.

Over the past few months ever increasing hype has been surrounding the emergence of a new type of battlefield; one that does not exist in the tangible world. The threat of cyber warfare and cyber terrorism has been the subject of intense debate and media interest, gaining significant presence in The National Security Strategy outlined by HM Government in October of last year and in the Security Threat Report published by Sophos (an internet security company) in January 2010. If a fully fledged cyber attack were to be implemented against this country, we could expect all the following systems to be potential targets:

CERN Series:Part I
Motivation For The LHC And The Standard Model The Large Hadron Collider is the most ambitious particle accelerator ever created. However, the basic principle of accelerating particles to learn about advanced physics is not new. The LHC builds on several decades of success in particle physics, both at CERN and elsewhere, Julian Evans explains some of the physics they hope to understand from this. So why do scientists want to accelerate particles anyway? When this was first achieved in the early 1930s, the eventual goal was to induce nuclear fission (splitting the atom) by firing an energetic particle into a large atomic nucleus. However, during some of these early experiments, new particles such as the muon were discovered. This prompted advances in particle acceleration and detection, to reach higher energies and to see what other particles could be found. By colliding two fast-moving particles together, the energy available to create new particles is even higher. The 1950s and 1960s saw the observation of a whole raft
of new particles. Initially it was supposed that they had no substructure and that there could be an infinite number of these, but theoretical physicists concluded that all matter is made from a total of 12 quarks and leptons, and that antimatter (particles which have the same properties as matter but with opposite electric charge) is made of 12 antimatter equivalents. All interactions between particles occur due to four different forces, which have carrier particles called bosons. However, not all of these had been discovered at the time. The theory based on these particles has become known as the Standard Model, and it still describes most of parti-

The lightest, most stable are the down and up quarks, which form the protons and neutrons which make up the nuclei of atoms. The strange and charm quarks are less stable, and particles made from these, such as the kaon and lambda, were first discovered around 1947. The unusual choices of name represent the strange quark being quite unexpected, and the charm quark being a very welcome find due to it making the theory symmetric. The bottom quark was not discovered until 1977 and the top quark not until 1995, both at Fermilab in Illinois, USA. They have much

The four forces of nature are gravity, electromagnetism, and the weak and strong nuclear interactions. Each is carried by a particle, except for gravity. Electromagnetism is carried by the photon, a “packet” of light. The strong interaction is carried by gluons, which act on the so-called colour charge of quarks. The weak interaction is carried by the W and Z bosons, which were discovered in the late 1970s at CERN, shortly after they had been theorised. This was another major success for the Standard Model. It is still not complete, however. The one theorised particle yet to be discovered is the Higgs boson, which gives mass to the others, and is needed to
some more of particle physics’s current mysteries. For example, one might reasonably expect that due to the symmetrical nature of much of physics, that there might be equal amounts of matter and antimatter in the universe – however significantly more matter has been observed. Much of the mass in the universe is dark matter, the composition of which is still unknown, and it is thought that this may be supersymmetric. There is no direct evidence for the existence of supersymmetry yet though, and there are many other theories which attempt to explain the nature of the universe. All we can do for now is wait for the right collision. Julian Evans

The BP Crisis : When are we going to stop? In the aftermath of another devastating oil spill, Andrew Wright invites readers to discuss the world’s environmental crisis and if it can be addressed before it’s too late. After BP set about trying to fix what is now another painful chapter in our planet’s growing list of man-made disasters, the old question of energy sources and usage is arising once more, and some are beginning to wonder how much longer we can keep using oil and fossil fuels to sate our world’s ever growing demand for power.

SATNAV Magazine at the University of Birmingham to build and to run, the power stations tend to split opinion to whether the nuclear industry should be allowed to grow or to be stopped altogether. Nuclear energy is a very efficient form of gathering energy, and technology has certainly improved since the 1990’s to ensure the safe use and security of radioactive substances. But like oil, accidents at nuclear power plants can be so devastating that it causes many people to be very wary of using nuclear power. However nuclear power is much less destructive than using non-renewable sources, and at the current time other cleaner sources cannot compete with the power output of nuclear energy. Couple this with the amount of land usage it would take to establish enough wind and solar farms to compete with nuclear energy, nuclear seems like a sensible option that will most likely be a major source of our energy in the near future. Renewable Energy: Clearly the most favourable option, but as of yet we are struggling to efficiently harness many clean forms of energy which are viable for the future. Wind farms are the best option when we consider renewable energy, turbines can be installed offshore, and farmers can lease tiny amounts of land to install a turbine on their property. It is free and the cost of setup can be recuperated in about 9 months. However, because of the amount of land that wind turbines use, large scale wind farms may not be feasible, and at the current time fossil fuel plants are still used to backup wind energy due to the intermittent nature of harnessing it. Solar energy is another popular choice, but converting the power to useful energy in houses is very inefficient with the current technology, however new technologies are being used to
increase the efficiency and over the next century we may start to see solar power as one of our main sources of energy. Hydrogen fuel cells will be a direct step in trying to replace the use of oil for fuel, but may still require energy plants to create the hydrogen to be used for fuel, unless cleaner ways of harnessing hydrogen are found. Choices are still yet to be made regarding new forms of energy and this writer thinks that we may be leaving our decisions too late. In such an important phase in mankind’s history, we should be planning well ahead to try and avoid any problems in obtaining energy in the future - problems which could include the denial of fuel to large countries which could result in political tension and even war.
Who is to blame for this?

With fuel poorly be planning well taxed and emisahead to avoid any sions poorly problems in obtainregulated, companies such as ing energy in the BP are put under future immense pressure to drill in more dangerous places, and with the obvious risks attached, maybe we should not be so surprised to hear that the Gulf Oil Spill is our fault too. We demand cheap oil, and are aghast when petrol rises by a few pence. Many of us have no qualms when driving to work when a bus or a bike is better. We all know how to be more environmentally friendly, but maybe we’re not trying hard enough. In one way or another, we are all intrinsically linked to that oil spill, and hopefully this terrible accident will serve as a message to some that we all need to shoulder the blame for the spill and what we are doing to our planet.
It is easy to make an example out of BP for such carelessness when dealing with such a damaging substance, but we are surely all to blame for this. We ourselves waste huge amounts Andrew Wright of energy each day. Governments across the globe have only recently started to really focus towards making our planet cleaner, a decision which should
