How much is your DNA worth? As millions of people pay for home tests to check on ancestry or health risks, genetic data is becoming an increasingly valuable resource for drug makers, triggering a race to create a DNA marketplace.
Diatoms are tiny, unicellular creatures, inhabiting oceans, lakes, rivers, and soils. Through their respiration, they produce close to a quarter of the oxygen on Earth, nearly as much as the world's tropical forests. In addition to their ecological success across the planet, they have a number of remarkable properties.
The US government, under court order to quickly reunify parents and children who were separated after crossing illegally into the United States from Mexico, has expanded its use of DNA tests to establish paternity in immigration matters.
Scientists in Sweden reported a nanoengineering innovation that offers hope for treatment of cancer, infections and other health problems —conductive wires of DNA enhanced with gold which could be used to electrically measure hundreds of biological processes simultaneously.
A new research has revealed that during the late Pleistocene epoch, some 20,000 years ago, the first group of Paleo-Indians with a distinct genetic makeup, now called Ancient Beringian, entered the present day Americas and persisted in Alaska for about the next thousands of years.
