Durham, NC - The question of how life began on a molecular level has been a longstanding problem in science. However, recent mathematical research sheds light on a possible mechanism by which life may have gotten a foothold in the chemical soup that existed on the early Earth.

Researchers have proposed several competing theories for how life on Earth could have gotten its start, even before the first genes or living cells came to be. Despite differences between various proposed scenarios, one theme they all have in common is a network of molecules that have the ability to work together to jumpstart and speed up their own replication -- two necessary ingredients for life. However, many researchers find it hard to imagine how such a molecular network could have formed spontaneously -- with no precursors --from the chemical environment of early Earth.

"Some say it's equivalent to a tornado blowing through a junkyard and assembling the random pieces of metal and plastic into a Boeing 747," said co-author Wim Hordijk, a visiting scientist at the National Evolutionary Synthesis Center in Durham, North Carolina, and a participant in an astrobiology meeting held there last year.

In a previous study published in 2004, Hordijk and colleague Mike Steel of the University of Canterbury in New Zealand used a mathematical model of simple chemical reactions to show that such networks might form more easily than many researchers thought. Indeed, biochemists have recently created such networks in the lab.

In a new study published this year, Hordijk, Steel, and colleague Stuart Kauffman of the University of Vermont analyzed the structure of the networks in their mathematical models and found a plausible mechanism by which they could have evolved to produce the building blocks of life we know today, such as cell membranes or nucleic acids.

"It turns out that if you look at the structure of the networks of molecules [in our models], very often they're composed of smaller subsets of molecules with the same self-perpetuating capabilities," Hordijk explained.

By combining, splitting, and recombining to form new types of networks from their own subunits, the models indicate that these subsets of molecules could give rise to increasingly large and complex networks of chemical reactions, and, presumably, life.

"These results could have major consequences for how we think life may have originated from pure chemistry," Hordijk writes.

The study will appear in the December 2012 print issue of the journal Acta Biotheoretica.

As part of an ongoing effort to engage with customers, Sheds Unlimited of Lancaster PA recently launched a Sheds Unlimited Customer Reviews page. Within one month many reviewers share their satisfaction with Sheds Unlimited.

Lancaster, PA (PRWEB) November 26, 2012

For over two decades Sheds Unlimited has been manufacturing and shipping storage sheds and prefab car garages throughout the northeastern part of the United States. But the recent addition of a storage shed reviews page has customers raving about their sheds and garages. Read through the glowing five star opinions on the Sheds Unlimited reviews webpage and you will almost certainly be convinced to buy from this family owned and operated small business. In fact, only two of the reviews show less than a five star and those for only minor issues which were either misunderstandings or easy fixes.

Several customers talk about the delivery process which was seamless, others rave about the cheap pricing and still others discourage customers from wasting time looking to other builders as they did. Dont bother shopping around for price and quality as I did, says one customer These guys are the best! Another writes about the delivery man who was like a family member the way he was concerned with proper placement...he wanted it placed correctly almost, if not more than me!! writes Pat, another customer with an extensive five star review of Sheds Unlimited.

Quality customer service and quick repairs are another outstanding feature of several of the newest garden shed reviews on this growing list of satisfied ratings. Adam writes that the door shipped with his storage shed kit was not exactly as he had imagined. I contacted customer service, he writes, and they offered to drive up the right doors the next day and exchange them. He goes on to describe his shock that they would offer to replace the doors over what seemed a misunderstanding during the ordering. A broken door latch was also quickly resolved by the customer service department at Sheds Unlimited. His garden shed review shows the level of satisfaction with Sheds Unlimited.

Kathryn describes her situation of receiving a storage shed kit two days before a scheduled gathering of 100 people in her backyard. I was a bit nervous with all the preparations...and a shed kit sitting in my driveway. But the problem was resolved when the driver offered to go the second mile and help carry the kit into the backyard! It was enough incentive to start assembling it the next morning, she writes. The next morning, two men and two hours was all it took to have the shed assembled before the influx of people. I love my shed, says Kathryn as she expresses her gratefulness to the driver who helped make the process even smoother.

Sheds Unlimited is unique in that nearly all of their garden shed and prefab car garage sales come in through the internet and recommendations of other customers. We realize the importance of good customer rapport and are doing our best to create a strong base of happy customers who will come back to us and recommend Sheds Unlimited to their friends and neighbors, writes Chris Stoltzfus, the middle son of the family owned and operated company. Although not every customer could write such great reviews, the company strives for customer satisfaction.

Into the Storm Lessons in Teamwork from the Treacherous Sydney to Hobart Ocean Race
http://www.youwillrich.net The Sydney Hobart Yacht Race is among the most demanding sailing competitions in the world. Unpredictable seas make the 628-nautical-mile course grueling under the best conditions, but the 1998 race proved to be the most perilous to date when a sudden and violent storm struck. Winds gusted over 100 mph and monstrous 80-foot waves towered over boat masts. Six sailors perished and another 55 were saved in what became the largest search and rescue operation in Australia #39;s history. In the face of turmoil and tragedy, a crew of "amateur" sailors piloted their tiny vessel, the AFR Midnight Rambler, not only to the finish but to overall victory. While bigger, better-equipped yachts attempted to maneuver around the storm, Ed Psaltis and his crew made the daring decision to head directly into its path. Their triumph-perhaps even their survival-owes itself to an extraordinary level of teamwork: an alchemy of cooperation, trust, planning, and execution. Into the Storm chronicles their nearly four-day ordeal and draws parallels to the world of business, revealing 10 critical strategies for teamwork at the edge. Illustrated with examples from the story and compelling case studies, the book sheds light on what teams need to do to succeed in tough times. Finally, Into the Storm provides resources and tools to support teams as they navigate the chaotic seas of business today.From:Nguyen kinh luanViews:1 0ratingsTime:03:31More inEducation
