The U.S. FDA is seeking public comments on a new technology that has the potential to circumvent mitochondrial diseases by producing embryos using DNA from three people.

Researchers suggest that a standard prenatal tests should be stopped and that a new prenatal DNA test should become the new standard to detect Down syndrome in fetuses.

On February 25-26, the U.S. Food and Drug Administration (FDA) will hold a public meeting to discuss intentional genetic modification of children and their descendants.

Leipzig - Researchers have traced the mixing of human populations using DNA and from this a special map has been created, encompassing over 100 events occurring over the past 4,000 years.

Paris - After a jewelry heist in Paris, a 20-year-old French criminal's self-stated "compassion" for his female hostage led to his arrest. Police could identify him from the DNA he left behind on her cheek.

Boston - Scientists have identified abnormal expression of genes, resulting from "DNA relaxation," that can be detected in the brain and blood of Alzheimer's patients. This offers a clue of a genetic link to the degenerative disease.

Scientists have pioneered a new gene sequencing method to test for abnormal DNA in cancerous tumor cells. This method paves the way for routine genetic testing in personalizing cancer care.

Two new studies demonstrate the extent of Neanderthal DNA that persists in modern human genomes. The genetic relationship is far greater than previously thought.

Hardingstone - A forensic team from the University of Leicester (UK) have opened an investigation to try and identify the victim of a gruesome murder case from 1930. This was the same team who, last year, identified the body of King Richard III.

Homo sapiens and Neanderthals co-existed on earth for thousands of years. Then, about 30,000 years ago, the Neanderthals became extinct. Last year, a near-complete reconstruction of the Neanderthal genome was published, showing some interesting results.
