It is estimated that digital data will reach 44 trillion gigabytes by 2020, a tenfold increase from figures in 2013. That's enough to create six stacks of computer tablets reaching the moon! Will there be enough storage? Researchers from Microsoft and the University of Washington (UW) are looking to address this issue by turning to DNA as a storage solution.
In a study, the researchers detailed a new technique they have developed which allowed them to successfully encode four image files worth of digital data into the nucleotide sequences of snippets of synthetic DNA.

More importantly, they were able to reverse the process and retrieve the right sequences representing the encoded digital data from a larger DNA pool and reconstruct the four images without compromising an information byte.
"We're essentially repurposing [DNA] to store digital data ... in a manageable way for hundreds or thousands of years," said Luis Ceze, co-author for the study and UW computer science and engineering associate professor.
Molecules of DNA are capable of storing information more densely millions of times than current storage technologies, which also deteriorate after several years. DNA, on the other hand, not only has an infinitely larger storage capacity but can also last for centuries, making it perfect for archival purposes.
Currently, the biggest challenge to using DNA as a storage solution is the cost and efficiency associated with synthesizing and sequencing DNA on a larger scale. With the right incentives in place, however, the researchers are confident that any technical barrier can be overcome.
Using DNA as storage mostly relies on biotechnology techniques, but the practice can incorporate new expertise as well. For the current study, the researchers took advantage of error correction schemes that have not been used on DNA before, just in computer memory.
Other authors for the study [pdf] include: Karin Srauss, Georg Seelig, Douglas Carmean, Randolph Lopez and James Bornholt. They received funding support from the David Notkin Endowed Graduate Fellowship, the National Science Foundation and Microsoft Research.

PARIS – In a step forward for organ regeneration, stem cells grown from a single monkey’s skin cells revitalized the damaged hearts of five sick macaques, Japanese scientists reported Monday. The experiment builds toward the goal of providing a vast and noncontroversial source of rejuvenating cells to transplant into heart attack victims, researchers wrote in the science journal Nature.

People aged 45 and over at greater risk of heart disease if they work in sales, office support roles or service occupations
Those in management or professional roles are at lower risk, experts say
Heart disease is the leading cause of death around the world
Experts analyzed 7 key indicators of heart health - blood pressure, cholesterol, blood sugar, exercise, diet, weight and smoking
Take simple steps, such as a walk at lunch, to improve health, say experts
