Primordial DNA spontaneously appeared 4 billion years ago

Posted: Published on April 7th, 2015

Scientists say early DNA-like fragments guided their own growth They claim the process can drive the formation of chemical bonds These connect short DNA chains to form long ones for life to evolve This self-assembly capability has been shown to take place in RNA By Ellie Zolfagharifard For Dailymail.com Published: 12:53 EST, 7 April 2015 | Updated: 14:27 EST, 7 April 2015 Scientists believe life on Earth began evolving around 3.8 billion years ago. But while they have been able to put a date on when life appeared, they are still far from knowing how it appeared. Now researchers in the US and Italy say they have evidence that DNA-like fragments may have come with 'instructions' that guided their growth into complex life forms 4 billion years ago.

A Step Closer to Eternal Data Storage in DNA

Posted: Published on April 7th, 2015

Methods for storing data in DNA are becoming more feasible, and may now enable the data to survive intact for over a million years. Researchers in Switzerland have recently conducted successful experiments in this field. The idea of storing data in deoxyribonucleic acid (DNA), the natural genetic information storage medium, has been around for a number of years. Scientists have already known for some time that information could be stored in a DNA sequence. Now researchers at the ETH Institute of Technology in Zurich, Switzerland have taken a further step towards achieving uncorrupted data storage for a period approaching eternity. Robert Grass, a lecturer at the ETH Department of Chemistry and Applied Biosciences, and his team set out to test the procedure, basing their research on preserving the information-bearing segments of DNA. The technique used by the ETH scientists to encode and decode data from synthetic DNA In order to do this, they drew some lessons from fossilised bones. Scientists are able to isolate and analyse genetic material several hundreds of thousands of years old because it has been encapsulated and protected. The ETH research team encapsulated the DNA in microscopic silica spheres (essentially glass) with a diameter of roughly … Continue reading →

New study hints at spontaneous appearance of primordial DNA

While studies of ancient mineral formations contain evidence for the evolution of bacteria from 3.5 to 3.8 billion years ago -- just half a billion years after the stabilization of Earth's crust -- what might have preceded the formation of such unicellular organisms is still a mystery. The new findings suggest a novel scenario for the non-biological origins of nucleic acids, which are the building blocks of living organisms, said CU-Boulder physics Professor Noel Clark, a study co-author. A paper on the subject led by Tommaso Bellini of the University of Milan was published in a recent issue of Nature Communications. Other CU-Boulder co-authors of the study include Professor David Walba, Research … Continue reading →

PNoy approves Chemistry Profession Act

Posted: Published on April 7th, 2015

President Benigno Aquino III has approved the Chemistry Profession Act, which regulates and modernizes the practice of chemistry in the Philippines. Republic Act 10657, which Aquino signed last March 27, repealed Republic Act 754, the earlier law that regulated the practice of chemistry in the country. The new law expands the definition of chemistry and the scope of its professional practice. R.A. 10657 defines chemistry as the study, analysis, modification and calculations of physico-chemical or biochemical properties of matter. The newly signed legislation also mandates the creation of Professional Regulatory Board of Chemistry, which will be composed of three members appointed by the President. Members of the board will serve three-year terms. The board is tasked to supervise and regulate the practice of the chemistry profession in the Philippines, and to come up with implementing guidelines for the new law. Just like the repealed law, R.A. 10657 also requires an individual who wants to practice chemistry and in the Philippines to pass the licensure examination given by the Professional Regulatory Board of Chemistry.

Which Nicholas Sparks movies have real chemistry?

Posted: Published on April 7th, 2015

Once again, Nicholas Sparks is bringing his signature romantic stylings to the big screen with The Longest Ride, in theaters Friday. Starring Scott Eastwood and Britt Robertson as what else? star-crossed lovers, the movie joins a long line of Sparks movies crafted precisely to make the heart ache. While the jurys still out on The Longest Ride, history has taught us that the fate of a Sparks adaptation can depend largely on whether its leads mesh like peanut butter and jelly, or conversely, if they mesh like peanut butter and turkey. So lets rank, from worst to best, the stars chemistry in each of Sparks movies. Before she was Piper Chapman, Schilling was busy trying to muster a bit of interest in the kid from High School Musical. This movie made it very clear that the only woman Duhamel should be focusing on is Ms. Fergalicious and that the only thing Hough should be paid to portray is the part of reality TV dancer. The first adaptation of a Sparks novel places its characters in a dynamic that feels dated and inauthentic, something the actors cant overcome. It wasnt that the films two big stars didnt have any sexual tension … Continue reading →

Chemistry of Game of Thrones’ Valyrian steel sword

Posted: Published on April 7th, 2015

In Game Of Thrones, Valyrian steel was forged during the Valyrian Freehold It is said to be sharp, light, strong, heat resistant and dark with patterns Scientist has studied which materials could create a similar, real life sword And concludes it's not a steel at all, but is instead a metal matrix composite By Victoria Woollaston for MailOnline Published: 08:51 EST, 7 April 2015 | Updated: 15:09 EST, 7 April 2015 In Game of Thrones, the secret to forging super-light and strong Valyrian steel swords was said to have been lost with the Doom of Valyria. But, despite its fictional basis, a scientist has investigated whether it would be possible to make a similar weapon using bona fide chemistry. By studying the composition of modern steel, welding techniques and assessing all the characteristics of Valyrian steel, he concludes it isn't a steel at all, but instead is a metal matrix composite. Scroll down for video According to the Game of Thrones books, Valyrian steel is a form of super strong and light metal forged when the Valyrian Freehold governed Essos and covered more than half the known world. Ned Stark, played in the HBO adaptation of the books by Sean … Continue reading →
