Paternity Testing - Are You Raising Someone Else's Child?
The dawn of the DNA test
Back in the 1700s, the best way to determine paternity was by a good hard look and the child, followed by a good hard look at the father. Enough coincidences and maybe a relationship could be proposed. A hundred years later, eye color was discovered to be a paternity identifier. This theory has had its flaws exposed because of recent DNA advances. We now know that eye color is determined by at least six alleles, or genetic markers. Paternity testing has become a lot easier and affordable over the past few years due to advances in DNA science. Although a ...

Allow Mother Nature some Dignity
For every action there is a reaction. So said Newton. Although he was referring to the law of motion, I think that this law can also be applied to nature. Even if we toss away a sweet wrapper, a bird may use it to build a nest. A child may spill their cola and soon enough some ants may come along and feed on it. If we construct a building where there used to be wasteland, then nature will react. Some creatures will avoid the new building; others will be attracted to it. In recent times some authorities have built special underground tunnels for badgers under new roads. In fact there a ...

a href=http://www.physorg.com/news3571.htmlNew miniaturised chip dramatically reduces time taken for DNA analysis/abrbrThe portable device will speed up performing paternity tests, identifying bacterial infections and detecting genetically modified organisms (GMOs)A team of researchers at the Universitat Autтnoma de Barcelona has developed new miniature sensors for analysing DNA. The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain. These sensors can be applied to many different tasks, ranging from paternity tests and identifying people to detecting genetically modified food, identifying bacterial strains in foodborne illnesses and testing genetic toxicity in new drugs. Once mass production of the sensors begins, their cost and availability will be similar to that of pregnancy test kits found in pharmacies.brbrbra href=http://nanotechweb.org/articles/news/4/5/5/1?rss=1.0Nanocrystals highlight DNA mutations/abrbrResearchers at Arizona State University, US, have developed a technique that uses nanocrystals to detect genetic mutations. The method creates a bioelectronic signature for point mutations known as single nucleotide polymorphisms (SNPs). The ultimate goal is to make something similar to a hand-held glucose monitor for future genetic testing,? said researcher Joseph Wang. The electronic detection of DNA is a thing of beauty.brbrbra href=http://topix.net/r/0G3UF8Xfk0N0K2FaUJHRPr=2BeN4F5yVPpj=2B87k4yb6Yi1h1=2BaV8Q6KeFsFINJT3sfPciMM9uc2KtOhyd5SKujNJ07KNFph44xEEDu0=2FiVrEcgvf3ikxN1NGpbEsRRQIUzbGenetic testing races toward day when diseases can be predicted/abrbrDoctors can now take a few of your cells, pull out the DNA, stretch it across a screen and diagnose more than 1,100 genetic defects that could mean trouble, ranging from rare disorders to more common ones like ...brbrbra href=http://genealogyblog.com/?p=4085Grandpas Genes, the Ancestral File, and Current Genetic Research/abrbrThe Utah Medical Association and Heritage Genealogical College are planning a genetics and professional genealogy seminar, Grandpa's Genes, the Ancestral File, and Current Genetic Research. ....

Our Youth Need a Comprehensive Mentoring Program
We must challenge our youth to go beyond and excel in all they do, help them when they fall and guide them to the traits we will need when it is their turn to lead. There are many great programs for youth, sports, band, student government, Scouts, etc and we have so many dedicated servants to the cause of this public good. We have done so much, but it is time to take it up a notch, integrate the technologies we have for teaching and press on to the highest possible level of mentoring. We know mentoring works and we must use that innate social interaction of our species to the best of our ab ...

Human Motion, Walking, Running and Gait for Identification
Identifying a human gait, walking patterns, running exists. Can such records be of value? Many think so. Why is this so important? Well every time Bin Laden is on TV no one knows if it is real or not. You cannot take a DNA sample, no retina scanning, fingerprints, well then facial recognition? Harder on video tapes at only one angle. Some ones gait could be viewed and downloaded by a sniper to decide if this is the correct target, although chances are it is best to kill all the doubles anyway, the fewer they have the closer you are to the primary targets. We can certainly thank the mo ...
