#Genes could be answer to saving out dearly beloved #data - http://clapway.com/2015/08/18/to-preserve-digital-data-dna-will-be-the-save-button-of-the-future-323/

Researchers believe we will soon be able to use DNA to encapsulate our most precious digital data, meaning that the building blocks of our bodies may soon be the very thing that will become the hard drives of the future.


The Challenge of Preserving Digital Data


Digital data has become so prevalent in our lives, it is almost hard to remember the times when we didn’t require usernames and passwords to access our memories, our friends, and our social lives. However, with the added convenience of modern technology has come a very real problem in the relatively short shelf-life of these very devices that we rely on to store all our information.


This week, a team of researchers presented their work of using DNA in digital data at the 250th National Meeting & Exposition of the American Chemical Society (ACS). The novel research has been able to alleviate the issues of longevity in regards to modern technologies, like the hard drive, which always inevitably fails (especially when we need it the most, it seems).


Robert Grass and the researchers at ETH Zurich have been able to store and translate digital data using DNA, touting a remarkable preservation life of over 2,000 years for the data their transferred.


For some of us, we wouldn’t mind losing digital data from our past (I’m looking at you, Myspace and old Xanga blogs from middle school); much of the information we do save that may be necessary in the future can really benefit from this new technology.


How ETH Zurich Will Evolutionize the Save Button for Digital Data in the Future


Grass and the other researchers from ETH Zurich noticed a major flaw in how we save our digital data. Our hard drives wear out and not in hundreds of years, but just a few decades. Meanwhile, archaeologists are unearthing books written hundreds, if not thousands of years ago with perfectly preserved information.


DNA is getting a lot of buzz in the press


The researchers realized that the key to preserving the old relics was in the DNA. It proved a worthy technology as it used a four code sequence (remember biology class when you learned A-T-C-G bases in DNA?) whereas our computer systems use a similar structure called binary, which is comprised of 0’s and 1’s to encode data. But more than that, DNA had two major factors.


The first factor is the extremely small size of DNA, which is definitely needed if all the information in this digital age is going to be stored for thousands of years. Think of the average external hard drive, which is similar in size to John Green’s latest paperback book. That one hard drive can only store approximately 5 terabytes of information. In comparison, DNA can store over 300,000 terabytes, in only a fraction of an ounce of DNA.


While size does matter in this context, durability is the second factor and probably just as important to ensure the safe encoding and storage of digital data. That external hard drive you have may last about 50 years, but DNA has been able to be analyzed from thousands of years ago. What’s more is that the ancient DNA from archaeology and paleontology digs proves that this same DNA can still be sequenced thousands of years later.


Digital Data Technology May Use DNA-Based Hard Drives


Grass’ researchers have already encoded DNA with text from the Swiss Federal Charter and the Method of Archimedes, which comes out to be around 83 kilobytes of information.


Their findings revealed that after encapsulating the DNA, warming it to 160-degrees Fahrenheit for a week to replicate the conditions of 2,000 years passing by, they were still able to decode the information without any errors. Since that was a success, they are moving on to the next issue with DNA preservation of digital data: a filing system. Rather than having to decode the entire strand of DNA, the researchers want to be able to pinpoint the specific location of one file.


Digital DNA Storage Too Expensive? Maybe This Is A Better Option For You


Though the project has ensured the technology is available, whether or not it is within your price range will vary. With just a few megabytes of digital data encoding and storing costing upwards over thousands of dollars, unless you’re part of the elite upper class, the “old-fashioned” save button may be your only option for now.

Are our #Brains and #Memory doomed? - http://clapway.com/2015/07/27/neural-efficiency-hypothesis-proven-brains-of-more-intelligent-people-just-work-better-456/

What is it that makes a genius think the way that they do? A question that has been unanswered for years may finally have a solution thanks to the work of researchers at ETH Zurich. The team of scientists has been able to prove conclusively what is known as the neural efficiency hypothesis. This remarkable breakthrough in the scientific understanding of the composition and functionality of the human brain is one more step along the path to discover everything that makes the human mind so miraculous.


Proving the neural efficiency hypothesis


Previously unproven for years since it was developed by scientists, proving the neural efficiency hypothesis was no small feat. Professor for research on learning and instruction at ETH Zurich, Elsbeth Stern describes essentially what the neural efficiency hypothesis is, “when a more and a less intelligent person are given the same task, the more intelligent person requires less cortical activation to solve the task.”


Neural Efficiency Hypothesis -


Brains of those with higher levels of intelligence simply require less effort to perform exactly the same tasks as those with lower intelligence levels. These findings imply that a more intelligent person is cognitively capable of performing better than someone with lower intelligence levels. According to the research study when subjects of a higher intelligence were given difficult tasks they required far less resources to successfully complete the task, but when completing remedial tasks the functionality was revealed to be very similar.


Stern describes the nature of resource usage in research subjects “When both cars are travelling slowly, neither car consumes very much fuel. If the efficient car travels at maximum speed, it also consumes a lot of fuel. At moderate speeds, however, the differences in fuel consumption become significant.”


What does this do to aid future research into what separates us from every other species that has ever lived?


Solving the neural efficiency hypothesis has led some rather intriguing conclusions about intelligence. The study has shown that even with memory based exercises in regards to certain tasks (such as playing a musical instrument), when faced with a similar but slightly different task, those who have practiced have no advantage when it comes to new, but slightly different task. This conclusion suggests that is not possible to exercise certain facets of the human memory.

Implications of unwrapping the mysteries of the human brain


For thousands of years humans have made valiant efforts to discover what exactly it is that makes humans different from other species on earth. Until the last hundred years or so the understanding of how it all works was surprisingly limited due to a lack of resources, but thanks to breakthroughs in medicine and computers, our ability to understand what it is that makes us tick has grown faster than early scientists could have ever predicted. Every breakthrough brings us a little bit closer to unlocking the mysteries that make us uniquely human.
