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” »

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.

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.

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.

Separated at Birth — Reunited by Social Media and DNA Testing

Facebook is a great way to keep in touch with friends and family, but what about distant biological relatives you never knew you had? Sounds like the plot of a movie, right?

For twins Anais and Sam, Facebook and DNA testing allowed them to do just that.

Test Smartly Labs of Lee’s Summit is sharing the amazing story of identical twin sisters who found each other across the globe thanks to Youtube and Facebook.

DNA Mysteries: DNA Testing & Proof of Maternity

Though you’ve undoubtedly heard of DNA testing to prove someone’s paternity, are you aware that there is also maternity DNA testing?

Used less frequently than more well-known paternity testing, a maternal DNA test can provide medical verification of maternity when legal issues call for it, such as in the case of hospital mix-ups, foster care or adoptions, or during immigration cases.Maternal DNA testing took center stage when a Washington state woman was accused of falsifying maternity for her three children. In a strange turn of events, the DNA testing revealed that her deceased twin — who was actually never born — was somehow the mother of her children.Welcome to the first of our DNA mysteries —  read on to see how DNA testing cracked the case.
