CLONING

CLONING 

over time we have heard about cloning, but really that is the cloning, is successfully done something successfully is successfully performed in humans or animals or both, these are just some of the questions that come to mind about this topic.

Cloning is known as cloning process to achieve to make identical copies of cells, molecules and / or agency through its DNA.

when cloning is achieved should keep several things in mind...

• the first thing is to be cloned cells because you can not make or part of any organ clone or if you do not have such celelas that form the body.

• the second, as cloning responds to an interest in obtaining a copy of a particular organism, an adult organism and is needed because, just being at maturity is to know the characteristics of that organism.

• thirdly, as it is created asexually. Sexual reproduction impossible to obtain identical copies, since this type of reproduction by nature generates multiple diversity.

a case of known cloning was the sheep Dolly, who was the first mammal created starting from an adult cell and not only that but its creators managed to create a cell specialized for a particular tissue (mammary gland) which until then is not thought possible. at that time it was thought possible using a cell not SPECIALTY bone embryonic cell.

its creators were scientists at the Roslin Institute in Edinburgh (Scotland), Ian Wilmut and Keith Campbell. sheep born on July 5, 1996 and died on 14 February 2003. dolly had a really short life because this type of sheep live around 11-12 years. her six years of life February 14, 2003 dolly was sacrificed due to a kind of lung cancer called Jaagsiekte common in sheep.

Currently there are many research to achieve human cloning successfully and is that not only would be achieved clone a body as you know but through this research to achieve treat disease.

said that a team led by a scientist from Russia Shoukhrat Mitalipov has managed to produce human stem cells by transferring the nucleus. from skin cells, which have become embryonic stem cells capable of developing into any type of cell in the body.

this finding could be the start to treat some diseases by replacing damaged cells caused by an injury or some condition. among which are, Parkinson's, multiple sclerosis, or some injuries of the spinal cord. with the discovery of these scientists can improve disease suffered by millions of people.

DEJA VU

DEJA VU 

ave you ever thought you had gone or had experienced something because that is dejavu, it's something really funny though sometimes annoying, that feeling strange to try to understand and torture us.

There are two types of déjà vu or paramnesia:

Stop senti This phenomenon refers to something 'and meaning'.

- Déjà vécu: Usually translated as 'lived' or 'experienced'

In recent years the déjà vu has been subjected to serious psychological and neurophysiological research. His most plausible explanation is that déjà vu is not an act of "precognition" or "prophecy" but rather an anomaly of memory

the impression that an experience is "being remembered." This explanation is supported by the fact that in most cases the feeling of "memory" when is strong, but the circumstances of the "previous" experience (when, where and how it occurred) are quite uncertain.

Also, as time passes, subjects can exhibit a strong recollection of having been the 'disturbing' experience vu itself vu, but no memory of the events or circumstances that were "remembering" when they had that experience. In particular, it may be the result of an overlap between neurological systems responsible and short-term memory (events which are perceived as belonging to this) responsible for long-term memory (events which are perceived as belonging to the past) . 

Many theorists believe that the anomaly of memory happens when one conscious mind has a slight delay in receiving the perceptual inputs. In other words, the unconscious mind perceives the environment before the conscious mind. This causes one's consciousness perceives something that is already in memory, even though it is only an instant difference with perception. 

if you think they are now more interested in this experience because it is very intriguing and curious at the same time, right.

HUMAN BEING IS RADIOACTIVE

HUMAN BEING IS RADIOACTIVE 

incredible as it sounds humans are naturally radioactive, without the need for some method to achieve so, this should not worry about alarming sound as it is normal and that'll explain below ......

todos los seres humanos somos radiactivo en mayor o menor medida y es natural ya que por el simple hecho de que el cuerpo humano esta compuesto de materia , y la materia siempre tiene algun porcentaje de sustancias que emanan o produce radiactividad.

Radioactivity occurs when the nucleus of an atom becomes unstable and breaks into pieces. In this tiny pop, smaller pieces, are thrown at high speed: electrons (known as beta particles), neutrons, helium nuclei (alpha particles), other larger nuclei which may, in turn, be radioactive and electromagnetic radiation (gamma rays). When that happens, we say that the atom decays

The radioactivity or radioactivity is a natural physical phenomenon, by which some substances or chemicals called radioactive, emitting radiation having the property of impressing photographic plates, ionized gases, producing fluorescence, through opaque to ordinary light,

An exhibition of high radioactivity can cause fatal damage to humans even kill within hours or weeks. here I leave many conditions that affect the body by exposure to radiation

• sickness

• vomiting

• seizures

• delusions

• Headaches

• diarrhea

• hair loss

• loss of teeth

• reduction in red blood cells

• reduction of white blood cells

• duct damage gastroinstestinal

• loss of bowel mucosa

• bleeding

• sterility

• bacterial infections

• cancer

• leukemia

• cataracts

• genetic damage

• genetic mutations

• abnormal children

• brain damage

• nervous system damage

• hair color change to gray

although this is very harmful to humans also has its good side, depending on the use made of, some of its use is the branch of medicine, in this radiation and radioisotopes are used as therapeutic agents and diagnostics.

Radiopharmaceuticals in the diagnosis of various studies are used:

· Thyroid, Liver, Kidney, Metabolism,Circulation, Heart,Lung, Gastrointestinal Treatment

In medical therapy with nuclear techniques can fight certain cancers. Frequently used treatments based on irradiation with from Cobalt-60 source gamma rays as well as, internal radioactive spheres, needles and threads of radioactive cobalt. Combining proper treatment and early detection of cancer therapies are obtained with successful results.

ARTIFICIAL INTELLIGENCE

 ARTIFICIAL INTELLIGENCE 

this is a really complex area which uses various sciences such as computer science, logic and philosophy. using these as bases try to give scientists the ability to reason to not live agent.

this science is done not only intelligent machines such as robots are what but also some kind of artificial brain and also intelligent computing programs and more.

STUART Russell and Peter Norvig differentiate these types of artificial intelligence

 

Systems that think like humanos.- These systems try to emulate human thinking; eg artificial neural networks. The automation of activities that we associate with human thought processes, activities such as Decision Making, Problem Solving and Learning

 

Systems that act as humanos.- These systems try to act like humans; ie, mimicking human behavior; for instance robotics. The study of how to make computers perform tasks that, for the moment, humans do best

 

Systems thinking racionalmente.- ie logically (ideally) try to imitate or emulate the logical rational human thought; such expert systems. The study estimates that make it possible to perceive, reason and act

 

Systems that act rationally (ideally) .- try to emulate a rational human behavior; inteligentes.Está losagentes such intelligent behaviors related artifacts.

we also have artificial brains that is research that aims to create either software or hardware with similar cognitive abilities of a human being.

is that many researchers have already ventured into this branch and creating several artificial brains. and the firm most familiar are our friends google to connect 16,000 processors created one of the largest nerural network in the world with over a million connections and the interesting thing is what interested this artificial brain was searching mostly images cat.

we also have the humanoid robot measures 80 inches high, and works with a learning system capable of assimilating the knowledge generated with every interaction with the environment. In this way he managed to meet targets such as balancing on one or two feet.

ARTIFICIAL BRAIN AND THE IMMORTAL MEDUSA

ARTIFICIAL BRAIN AND THE IMMORTAL MEDUSA 

just read the name of these life forms as it were, we can see how interesting and fun it can be to any reader and because it is a question that even a simple doubt there somewhere in our brain, is that this event thought was impossible existence. Here is bringing another slap that tells us that technology can almost everything.

over time and according to technology and science each inventor, scientist, physicist, mathematician, ect ...... looking forward every day finding either a new species, and invent something that is useful to the world . this time found a species of jellyfish which is immortal

  

IMMORTAL MEDUSA (Turritopsis Nutricula)

It's kind of hidroideo hidrozoo of Oceanidae family and has a life cycle which reverses when it reaches sexual maturity. bone is the only known case of a lifestyle that after reaching sexual maturity achieved reverse this process coming or going back to a sexual immaturity.

Turritopsis nutricula is able to achieve this very impressive event THROUGH cell transdifferentiation process. theoretically this cycle can last indefinitely making it what we call immortal.

Fertilized eggs develop in the stomach cavity of the larva (plánula). The eggs then planted in the seabed in colonies of polyps. The jellyfish incubated after two days. It becomes sexually mature after a few weeks (the exact duration depends on the temperature of the water: 20 ° C between 25-30 days at 22 ° C for 18-22 days).

the curious thing is that this jellyfish to reach a state of full or full sexual maturity later very little and yet is immortal certainly nature is grand and yet we still have much to learn because every year there are thousands of species new.

All jellyfish have a fixed life cycle differing only in hours or months respectively having only exepcion of nutricula turritopis which is immortal.

scientists are trying to learn more about this dorma of life peculiar and as we know this would only be the beginning, imagine that could try to use this type of research as important as what is immortality.

ROBOTS AND MEDICINE

ROBOTS Y MEDICINA 

robotics to progressed faster than many imagine, because although we are not as advanced as in the movies, certainly not that we are so far much so that we have multiple robots with specific tasks, in this case in the area of medicine.

Very few people actually thought a few years ago that what we know as robots could be true, well at least not so soon, but so far have manufactured various types of robots or machines for the purpose of accomplishing a task especially as what is the Japanese robots robots RIBA or nurse CODY.

RIBA.

This is a type of nurse and assistant robots programmed to do various things such as lifting patients out of bed, take them to the wheelchair, take them to the bathroom and help them get out of bed and not only that also equipped with wheels rotating at 360 degree angles so as to recognize faces and voices.

as we see the robots can be very useful even for domestic use for people with some kind of physical disability, just depends on what you want and can give, and this is just the beginning in the evolution of robotics.

It already is working on a new model of this robot so far I understand is called riba II and launching stage is dated 2015 and would cost about 54,700 euros or about 77,600 dollars approximately

CODY.

This robot has a very specific task is to give a sponge bath to the sick and that this task is very tedious for both nurses who are a little good let's skip that part and the patient who is quite embarrassed.

The good thing about Cody is how clean the patient, as it does in a very abrupt manner as would be normal, but it has joints that makes the robot does not make a very strong pressure on the patient, so that cleanability but also be delicate in this task.

ESSENTIAL TOOL ( THE CLOCK )

ESSENTIAL TOOL 

This little friend here is one of the oldest tools that the human being and though simple is your model is very important because its only use is not only tell time as you know.

It is called clock to instrument capable of measuring natural time (days, years, moon phases, etc.) in conventional units (hours, minutes or seconds).

this mechanism evolved as time passes, going from analog to digital. in the next picture we see a clear example of an antique clock.

watches whose main task is to tell the time, but is not limited to that and you can use him according to his carrier such as measuring the length of something, some military task, activate any Senar this serves as a guide depending the task you want to do with it.

over time have produced more accurate than they had in antiquity leaving behind their obsolete model which are the analogues and giving way to the new age digital watches bone.

with his invention was left to calculate the passage of day according avansaba the sun in the sky because this method but good since many do not as accurate as having a clock hand. so much so that it has become fashionable and / or need to have some type of watch either hand, in a cell, pocket, salon, etc.
