Could Your DNA Test Be Compromised?

When you get a blood test it is generally for two reasons — either to satisfy your genealogical curiosity or for use as evidence in legal proceedings. Accuracy is especially crucial in legal cases, where the results carry serious consequences. Not all DNA tests are legally admissible, only DNA tests that have a thoroughly documented chain of custody can be used in court. This requirement prevents DNA tests from becoming compromised, which can happen in any one of the following three ways. Continue reading “Could Your DNA Test Be Compromised?” »

Keep Your Children Safe By Creating a Child DNA ID

The world we live in today may be safer than ever due to our amazing advances in technology. However, it doesn’t mean that there aren’t any threats to our families out there. Keep peace of mind and know your children can be found in the event of an emergency by creating a DNA identification profile. Continue reading “Keep Your Children Safe By Creating a Child DNA ID” »

Crave Sweets? It Could Be Due to Your Genes

The gene FGF21 provides the instructions for creating a hormone of the same name; it is linked with food regulation in rodents and nonhuman primates. This new insight suggests FGF21 might actually moderate some appetites in humans as well. Interestingly, the work also suggests that the liver, which secretes the FGF21 hormone and controls insulin resistance, could be playing a larger role in snack management because it produces this hormone and communicates with the brain.

How Scientists Are Trying to Fight the Opiate Epidemic

There are many theories out there about drug addiction, whether you believe it is due to a moral corruption or believe it is an illness, there is no denying that America is in the midst of an opiate epidemic. There are people on the ground trying to help those struggling but without hard scientific “fixes” all we can hope is that the body count won’t continue to rise.

Chlamydia-Damaged DNA Could Lead to Cancer

How much do we as a general public know about sexually transmitted diseases and infections? We know we don’t want them and they can be dangerous, but what makes them so dangerous? Some diseases are resistant to treatment because it mutates DNA. Chlamydia trachomatis is the leading cause of bacterial sexually transmitted disease all over the world. Over 90 million new cases of genital infections occur every year. Continue reading “Chlamydia-Damaged DNA Could Lead to Cancer” »

DNA Testing Advances to Help Exonerate & Convict More Accurately

New advances in DNA testing technology can now differentiate identical twins and distinguish between two separate, but extremely close, sets of DNA. This is changing how criminal investigations can be solved, even cold and closed cases.  Continue reading “DNA Testing Advances to Help Exonerate & Convict More Accurately” »

DNA Testing Identifies Your Risk of Developing Heart Disease

In recognition of National Heart Health Month, it’s a great time to look at an advance in DNA testing that could predict your genetic predisposition to heart disease. Many Americans don’t know their family health history, would you consider it worthwhile to know your risk of developing heart disease? Continue reading “DNA Testing Identifies Your Risk of Developing Heart Disease” »

Selective Organ Therapy Possible with DNA “Barcode” Testing

Using tiny snippets of DNA as “barcodes,” researchers have created a new way of rapidly screening the ability of nanoparticles to deliver therapeutic genes selectively to specific organs in the body. This technique has the ability to accelerate the development and use of gene therapies for killers like heart disease, cancer and Parkinson’s. Continue reading “Selective Organ Therapy Possible with DNA “Barcode” Testing” »

Activity Level Could Be Linked To Cell Age

In a study at multiple U.S. universities, funded by the National Heart, Lung and Blood Institute, it’s recently been reported that women who lead a sedentary lifestyle could have faster aging cells than those who exercise on a regular basis.

What Do Your Genes Really Determine?

Genes are the basic heredity unit for everything about you from your hair, eye and skin color to how you write, cross your arms and sneeze. The Human Genome Project estimated humans have between 20,000 and 25,000 genes. Most are the same through all people, it’s only about 1 percent of the total that are unique; these alleles are what distinguished our different physical attributes.
