El Maganetismo y la mutacion

The Magnetism is called him physical fenómeno to which he exercises attractive forces before some objects, the nickel, the cobalt the iron and the alloys there is called they magnets. That which everything influences the magnetism for which it is a flame the magnetic field. It is a force of the nature, since likewise it it is the gravity. Also the gravity seizes that are attracted between if, the force of the magnetism comes from electrical loads. The magnets it has two poles, the north and the south around it I believe an area called magnetic field.

History of Magnetism
This magnetic phenomenon is said to be discovered by the Greeks, they first observed it in magnesia in South Asia, so I called "Magnetism" they noticed that some of the stones are iron attracted emanes called natural.
Is said to be produced by both artificial and natural magnets, where a magnet has two poles, north and south. When you want to pass an iron to a magnet that has the ability to attract more toward objects.
It was believed that only existed in magnetism magnets, Hans Christian Oersted in 1820 discovered that a thread circulating a current which exerted a magnetic disturbance in their environment.
Etymology of the name magnetism or magnete

    Stones' Magnesia and Magnet "(of magnesiaco, magnetism, magnetize) of gr. magnees (earth, metal and oxide) from city of Thessaly magneesia
    'Magnet', from Greek, adamas, adamantos (diamond steel) 'a' (privative prefix contariedad or denial) and damaoo (burn). Fig hard stone that can not be or should not burn, heat, as the Greeks had known that heat destroys magnetism.
    From the Latin magnes,-ETIS magnet.
    These stones were also known from ancient times as "stones lodestones" commonly called in Europe "yman" or "magnete, Ematite siderite and Heraklion».

Brief explanation of magnetism
Each electron is, by its nature, a small AMI. Ordinarily, many electrons are randomly oriented material in different directions, but in almost all electrons magnet tend to be oriented in the same direction, creating a magnetic force large or small depending on the number of electrons that are directed.
Besides the intrinsic magnetic field of the electron, sometimes you have to also have the magnetic field due to the orbital motion of the electron around the nucleus. This effect is analogous to the field generated by an electric current flowing through a coil (see magnetic dipole). Again, in general the movement of the electrons gives rise to a magnetic field in the material, but under certain conditions can be aligned movement and produce an overall magnetic field measured.
The magnetic behavior of a material depends on the material's structure, and particularly electronic configuration.

The home levitron is an object that gravitational forces are lost, since this creates its own gravitational force, a simple way to explain it is that two magnets repel reverse biased, since electrons of this are equal either positive or negative, usually it can be shown by taking two magnets magnetized and bringing them each for the north-pole either north or south-south, this causes like-charged electrons collide and form a gravitational force.
What is animal cloning?
Cloning is a way of assisted reproduction. The most common technique is known as nuclear transfer (SCNT), whereby a copy is produced from an animal gene replacing the nucleus of an unfertilized egg with the nucleus of a cell of the animal body to form an embryo. The embryo is then transferred to a female to develop in utero to term. As cloning technology advances also increases the possibility that food products produced from cloned animals or their progeny to become a commercial reality.
Legal status in the European Union
While foods derived from cloned animals are not regulated by specific legislation, meat from cloned animals fall within the scope of Regulation (EC) n. º 258/1997 concerning novel foods and novel food ingredients, and that cloning is considered as a new production process not currently used. However, it is still debated whether the food derived from the offspring of cloned animals is or is not a new food.
To clarify these issues, the Commission presented in 2008 a proposal for a regulation on novel foods to replace the aforementioned. In September 2008, the European Parliament adopted a resolution endorsing the ban on cloning. In 2009, to get an overview and to help advance the proposal, the Council requested the Commission to submit a report on animal cloning for food, which was released in October 2010. Finally, the lack of agreement on the labeling of food from cloning aborted the updating of the new foods.

Scientific evaluation
To regulate this issue, the European Commission (EC) requested two reports, one by the EFSA on the implications of animal cloning regarding safety, animal health and welfare and the environment, and other European Group on Ethics Science and New Technologies on the ethical aspects of cloning. EFSA issued an initial opinion in 2008, referring to the bovine and swine, which concluded that milk and meat produced from cloned animals pose no food safety issues different from conventional breeding or problems environmental safety. Regarding health and animal welfare, the technology itself that adverse effects to the clones and recipients. No adverse effects were observed in sexually reproduced progeny of cloned cattle or pigs. However, no study has yet reached the clones and their progeny throughout their natural lives. The EFSA has reviewed this first report in 2008 on two occasions, 2009 and 2010, and has validated the findings and recommendations.

    The EFSA Scientific Committee has issued a scientific opinion on food security, health, animal welfare and environmental impact of animals derived from cloning by nuclear transfer (SCNT) and their offspring and products obtained from these animals.
    The European Group on Ethics in Science and New Technologies has adopted an opinion on the ethical aspects of cloning.
    The European Commission is developing a new draft Regulation on novel foods that may include new technologies and facilitate intra and international trade of food products.

International situation
How is performed the cloning process?
Extract a oocyte (immature egg) of a female, and a micro pipette will extract the core, which is haploid, and instead insert a nucle diploid somatic cell-cloned body. Since the cell now has the full number of chromosomes, it starts to replicate and develop like any zygote. This is then grafted into the uterus of a surrogate mother like a "test tube baby". However, the process of implementing a new kernel, a cell can cause physical damage to the gene pool of the new being, as ocurrión to Dolly, who aged prematurely.
