Zachos, Elaina. "We Can Now Tell a Person 's Age Range From Crime Scene Blood." National Geographic. National Geographic Society, 29 June 2016. Web. 01 July 2016.
In her article “We Can Now Tell a Person’s Age Range from Crime Scene Blood”, Elaina Zachos describes a new discovery in crime forensics. At the State University of New York (SUNY) at Albany, chemists have discovered a method of determining a person’s age range by using a blood sample. The method involves determining the levels of alkaline phosphate (ALP), an enzyme that can be found in blood, present in the blood sample. Since active bone growth releases high levels of ALP in teens, researchers believe that they will be able to distinguish teens from adults. As you reach adulthood, the levels of alkaline phosphate in your blood began to fall.
To do this, the chemists added differing levels of ALP to human serum, a substance that mimics human blood. They let sample with higher levels of ALP represent young adults and the samples with lower levels of ALP represent older adults. The researchers used a method called biocatalytic assay which finds a specific chemical that is made by the enzyme’s behavior. They used this method to identify levels of ALP which in turn identifies the age group. With the success of almost 100 percent, they were able to determine the ALP levels and age ranges of each test sample.

...gly disapprove of using genetics to create “designer babies” with increased intelligence or improved physical appearance. He also highlights the mix supports of Americans for researching prebirth gene editing and other new genetic technologies. Other poll results showed that people strongly approved of the use of genetic editing to treat disease in children and adults, Begley reports. He points out that this poll is taking place at a critical time for scientist and policy makers, as they grapple with many issues surrounding the ethics of gene editing that the legal society faces. Begley states that due to a technique called CRISPR-Cas9, scientists have an increased ability to modify or repair genes. Due to the overwhelming lack of support for prenatal gene editing even for diseases, Begley infers that this may be a result of a lack of knowledge about the technique.

- Genomic sequencing is a test that is becoming more and more available and performed in the recent years. Although it is still not commonly used in the clinic, with the rate of advancement is it making, there is a good chance it eventually will be. When determining one’s genome there may be incidental findings, the data that the individual was not particularly looking for. These may be beneficial since they could provide information on susceptibility to particular diseases. Yet, not all conditions are actionable, therefore insight may also be provided on one’s chances of getting incurable or untreatable conditions.... [tags: Genetics, Human genome, Medicine, Cancer]

- Gene editing is one of the most researched fields of molecular biology as manipulated genes provide studying the specific genes and their effects. In the past, there were several attempts to manipulate gene function, including homologous recombination, RNA interference (RNAi), zinc-finger nucleases (ZFNs) and transcription-activator like effector nucleases (TALENs). These past approaches are expensive and time-consuming to engineer as opposed to Crispr Cas9, limiting their widespread use. What the Crispr Cas9 technique offers, and biologists desire, is specificity: the ability to target and study particular DNA sequences in the vast expanse of a genome with ease of preparation as used in Fu...

- “Genetic Engineering.” The World Book Encyclopedia. 2008 ed. This encyclopedia was extremely helpful. In not knowing all of the exact terms and basic knowledge of genetic engineering, it helped inform any reader of all this and more. The pages that had information on genetics and genetic engineering, had detailed definitions and descriptions for all the terms and ideas. Instead of focusing more towards the future of genetic engineering, it gave numerous facts about the technology and accomplishments of today.... [tags: Annotated Bibliographies, Genetic Engineering]

- The Middle East has since time immemorial been on the global scope because of its explosive disposition. The Arab Israeli conflict has not been an exception as it has stood out to be one of the major endless conflicts not only in the region but also in the world. Its impact continues to be felt all over the world while a satisfying solution still remains intangible. A lot has also been said and written on the conflict, both factual and fallacious with some allegations being obviously evocative. All these allegations offer an array of disparate views on the conflict.... [tags: Annotated Bibliography]
