DNA Robots Can Sort Molecules

In a study published in Science, researchers at the California Institute of Technology designed a group of DNA robots. They are called DNA robots not because they have “bodies”, “hands”, “arms”, and “feet,” but because they perform mechanical tasks at the nanometer scale. The robots’ current goal is to work together to find and collect fluorescent molecules. Continue reading “DNA Robots Can Sort Molecules” »

Psoriasis Keys Are Found in Your DNA

About two to three percent of the national population develops psoriatic disease, although scientists believe that at least 10 percent of the population inherit one or more genes that lead to the disease.  Continue reading “Psoriasis Keys Are Found in Your DNA” »

Researchers Make a Breakthrough Concerning Cancers Resistant to Treatment

Researchers from Monash University and the Memorial Sloan Kettering Cancer Center (MSKCC, New York) have discovered why some cancers, especially lung cancer and melanoma, are able to develop deadly resistances so quickly to targeted therapies.

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

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.
