DNA News: In Search for the Missing Girl
May 14, 2012 | 
Author A certain branch of Forensic science that makes use of genetic samples to identify people is known as forensic DNA. Nowadays, this is considered as the basic way in pointing out some criminals that consequently puts them in prison and also to find clues in of missing bodies.
In these days, the basic and the most typical way to implement certain crime investigation is byforensic DNA analysis. Crimes like rape, murder, and others are using this method. The process is basically easy. First, biological samples from a crime scene must be taken.These include some blood, urine, hair, saliva, semen, and vaginal fluids. These samples are kept in a sealed storage devoid of further contaminations.To do this successfully, taking another genetic sample from a suspected criminal or person is highly pressing.This will serve greatly for comparing both DNA analyses.In the case that a suspect is gone, genetic samples from his closely related persons like mother, father, siblings or offspring will do.Doing so will help determine whether the genetic samples matched with each other.
Today, Italian mafia tombed was open in search for the missing body of a 15 year old girl who was suspected to buried in the mobster tomb.
Fifteen-year-old Emanuela Orlandi, the daughter of a Vatican bank functionary, disappeared in 1983 on her way to a music lesson. Her body has never been found, and the truth about what happened to her has puzzled investigators for nearly 30 years. One of the most prominent conspiracy theories was that Orlandi’s remains would be found in the crypt where the notorious Roman mafioso Enrico “Renatino” De Pedis was eventually laid to rest after he was shot dead in a Rome square in 1990.

Due to the high accuracy of results, forensic DNA is now on the verge of being widely known. However, this famous system of identifying a person is somewhat beneficial for many. This is especially if the purpose is genuine. On the other, such is a potential danger for those victims of wise manipulation of a crime scene. A science like this has both the positive and negative side. It is us who uses it that can either make it good or bad. As long as we want the positive light that it gives, then it will always remain as positive. Otherwise, it will become a curse to everyone when wrongly used. Indeed, it will depend on you on what objective you will have to carry it out.

Gathering 2013 – Irish Ancestry Celebration
While you may wonder why it is so important to have ancestry be track; It is very much fascinating to know of what heritage and ethnic group you belong.
Numerous numbers of people have some identifying features helping them identify their line of ancestry. The misfortune is that many people have parents having different ancestry lines. Thus, making the diversification is too hard to track when merely looking back on previous generations with mixed ancestry. However, with ancestry DNA, it is possible to determine the ancestors of every individual. Because of this, it is now easier to trace back your ancestry lines if you want to. This will also at the same time help people in tracing their lost relatives.
Just like the upcoming event in Ireland, people will celebrate its ancestry by inviting everyone to come and visit Ireland. Not only that they encourage all Irish nationals across the globe to come back during this celebration.
Tracing your Irish ancestry, once a lengthy and difficult process, has never been easier than it is today. In anticipation of The Gathering 2013, a yearlong event promoted across the island by Tourism Ireland, genealogy centres around the country have been putting their records online to help people find their Celtic roots.

The testing that is involved in ancestry DNA process is made by the help of modern technologies available today. To carry out the ancestry DNA testing, the involvement of the Single Nucleotide Polymorphism is necessary. This is to ensure that the dominant ethnic group will be identified. Also, the Single Nucleotide Polymorphism can tell the percentage of the distinct ancestry groups that make up the individual’s DNA.

How Can Your Eye Color Determine Skin Diseases?
Several years ago, a branch of science, specifically in the medical science had found clues about pigmentation of the eyes being linked to certain illness and diseases. However, today’s discovery pointed out not the pigmentation alone but the color of the eyes itself.
Medical DNA in its simplest essence is the applications of information about DNA towards the medical field. The growing progress of which is directly influenced by the wonderful applications of genetic engineering. Such is widely focused on the innovations that will lead to discover acceptable treatments for maladies. These include those that were labeled as incurable like cancer, Alzheimer’s disease and many more. However, despite this, there are certain limitations that are unavoidable, which makes its progress limited in some places only.
The key point of Medical DNA lies on the utilization of DNA. This is necessary in order to achieve findings and treatments of certain diseases. With the advent of several advanced technologies, playing with DNA makes genetic engineers easier. However, it is certainly foretold that in some point in the future, clinical routines will become less challenging. Doctors will soon find their profession easier. This might be due to stress-free mode of diagnoses and therapies.
DNA being used to study diseases help researchers not only to treat the disease but also to hinder diseases from occurrence. Additionally, DNA help scientists to study more about the complexity of organism such as human.
The results showed that people with blue eyes were less likely to develop vitiligo. Meanwhile, people with brown eyes were more likely to develop the skin disease and its characteristic white patches of skin and hair.
Researchers say the findings suggest eye color may also have important implications on melanoma risk because the two diseases are related genetically.

The conspicuous thing about Medical DNA is the fact that it uses genes as well human DNA. This is a good idea wherein numerous people around the world can benefit its fruit. However, this can also be detrimental to human race. This is likely to happen, at any rate, of time as long DNA is in constant alteration. However, there is only a little chance that this can happen. The only thing that one must not forget is the idea this small chance. Even if this is just small, one must not take it for granted. This is to ensure protection against potential destruction on humans.

Researchers Discover a Cell that Plays a Vital Role in Treating Asthma
Scientists who are in the search for medicines that could treat asthma had finally discover a cell in mice that is similar to human with asthma. This cell is now the target of study by several experts in University of Michigan.
DNA testing is also called as DNA typing, or DNA profiling. This refers to a technique that is used by scientists in identifying respective DNA profiles to identify organism. A DNA possesses encrypted sets of codes that reflect on the persons’ DNA makeup. This serves as the person’s signature that enables him to be identified. For this, we can now effectively determine lost relatives with almost 100% accuracy. This is made possible, especially with the help of today’s technology. Thus, such a technique is useful in subjects like parental testing, criminal investigation and medical DNA.
Through DNA testing, researchers can now expound their research to be able to provide better solution and cue for certain diseases like asthma.
The U-M scientists have discovered a new type of cell in mice that appears to be crucial to causing asthma symptoms — even in the presence of steroid. The research, published in Nature Medicine, also showed that people with asthma have a very similar cell type in their blood at higher levels than people without the condition.
To carry out a DNA testing, it must conform first to a specific protocol used in a certain area. Such, a process will make used of DNA samples that vary from person to person. The test is employed using molecular methods like DNA arrays, DNA chips, and polymerase chain reaction. DNA testing requires biological samples like a few drops of blood, or cheek cell specimens. This can be obtained by rubbing a mouth with a swab. Sometimes, some companies provide free kit in collecting these samples at home. Furthermore, the sample will then be sent to a laboratory for the analysis. Such will undergo some controlled procedures like the extraction of cells from the swabs. After which the purification and harvest of the DNA material found within the cells will follow. The target parts of DNA sample are copied, and other parts are being separated from each other. After series of these processes, results are then analyzed.
Moreover, these processes are being repeated many times in order to confirm the result to achieve maximum accuracy. Thus, making reports will follow. However, the test may vary from time to time. This means that DNA testing depend so much on the purpose on why it should be done. Different objective mean different method to carry out the test.

DNA News: Smugglers of Suspected Capsules with Human Blood Hunted by the Korean Authorities
Medical DNA and DNA testing really plays a vital role in human health. Just as these days, more and more medicines are now being testing to check its content and to tell whether or not these medicines are safe to human.
Medical DNA has something to do with the applications of DNA breakthroughs, especially in the field of medicine. Its growing progress is the primary after effect of genetic engineering. This is the factor making it to have increased discoveries on new acceptable treatments for diseases like cancer. And certainly, this is maybe the answer for the issues of maladies that are thought to be incurable. However, certain limitations are unavoidable making this to flourish not in all places on the globe.
The utilization of DNA to achieve possible treatments on some illnesses is the key point of medical DNA. With the help of advanced technologies, genetic engineers can make use so much of their knowledge about DNA. Consequently, leading them to play a little more about it. Certainly, clinical routines will soon be changed. Diagnosing, and predicting maladies will soon be easier. Therapies as well as drugs that will cure the incurable diseases will also be discovered. The amazing part may fall on treating the unborn children for their possible risk of certain diseases.
With DNA testing, South Korean authorities were able to determined medicines that are unsafe to use. They are now hunting drug smugglers who were allegedly selling Chinese capsules which contain human bloods. Authorities did discover these capsules were sent from an international mail.
Since August, Korean authorities have discovered nearly 17,500 of the human-flesh capsules in the luggage of tourists and in international mail, the state-run Korea Customs Service said Monday. Disguised as performance-enhancement drugs, they have been smuggled in by ethnic Koreans living in northern Chinese cities.

In the practice of medical DNA, the obvious thing is it uses genes as well as human DNA. Although it is a good idea, such that its gained fruits can help millions of people from different places, it can also harm the human race as well. This can happen anytime when there is an attempt of altering the DNA’s true meaning. The harm is unlikely to happen but there is always a possibility. This possibility should, however, be treated as harmless, but it must be dealt with proper consideration. This is also in congruence to the fact that we are dealing with human. A medical DNA expert should therefore be on his positive direction so as to create medical breakthrough and not a medical harm. Such will ensure a positive weapon in the future generation’s battle against deadly diseases.
