Website hosting comes in several flavors, including Virtual Private Servers (also called VPS hosting), Content Distribution Networks (also called CDN), Shared Hosting, Dedicated Hosting, and much more. Why is web hosting important? Let’s say that you want to build a website for your new small business to promote your products and/or services to potential customers. One of the first things you’ll need is a web host, like Media Temple, to host your new website once it’s built. Think of it like building a new house. First, you need to buy land, even before building the foundation. Web hosting is like the land your website will be built on. Or maybe you’re an artist or professional who wants to create an online portfolio to showcase examples of your work. The type of web hosting services that you get for a portfolio may be very different from what you’d need for an e- commerce or small business website. That’s because the volume of traffic and resources needed for an e- commerce website is usually much higher than for a portfolio site. What kind of hosting plan is right for you? Whether you’re a seasoned blogger, brand new small business, budding artist, or even an e- commerce mogul, Media Temple has the best web hosting services for you. But before you choose a hosting plan, here are a few questions to help narrow down your search for the right plan. How many people are likely to visit your website? If you’re creating a portfolio, designed for a select audience, then a dedicated server might be overkill for you. Instead, you could save a lot of money by buying a shared hosting server. For low- to medium- trafficked sites, shared web hosting can be just as fast and secure as dedicated alternatives. Will your site need databases or secured areas? Understanding as many of the technical details of your website as possible before selecting web hosting services will help you get the right plan from day one. Of course, at Media Temple we realize that, although while we’re web engineers, you might not be. That’s why we keep a squad of full- time professionals on staff. They’d all be happy to look at your site, talk about your needs, and help you choose a hosting plan that’s a perfect fit. Web apps like Word. Press, Drupal, and Zen Cart can really help speed up your site’s development process. They offer pre- fabricated, out- of- the- box solutions for common problems that webmasters face. Knowing if apps like these will be useful for your website will also help you find the right web hosting services. At Media Temple, we offer a full range of 1- click apps, as well as G Suite. How do you know whether or not your host can scale? Scalable hosting is essential for growing businesses. Traffic slowly trickles in to new websites, but as they age and gain popularity across the web, their web traffic begins to grow. Sometimes this growth can happen at an astounding rate. But traffic costs bandwidth, and most hosting plans only come with a set amount of bandwidth. Media Temple believes that even fixed bandwidth web hosting services should be scalable. That’s why we created the world’s first scalable, shared hosting solution called the Grid. Ready to get started? You’ve made your plans. You know what you want. Now, let us help you make it happen. Explore our full range of web hosting services, or call us today and we’ll set you up with the perfect plan for your website. A New Thermodynamics Theory of the Origin of Life. Why does life exist? Popular hypotheses credit a primordial soup, a bolt of lightning and a colossal stroke of luck. But if a provocative new theory is correct, luck may have little to do with it. Instead, according to the physicist proposing the idea, the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.”From the standpoint of physics, there is one essential difference between living things and inanimate clumps of carbon atoms: The former tend to be much better at capturing energy from their environment and dissipating that energy as heat. Jeremy England, a 3. Massachusetts Institute of Technology, has derived a mathematical formula that he believes explains this capacity. The formula, based on established physics, indicates that when a group of atoms is driven by an external source of energy (like the sun or chemical fuel) and surrounded by a heat bath (like the ocean or atmosphere), it will often gradually restructure itself in order to dissipate increasingly more energy. This could mean that under certain conditions, matter inexorably acquires the key physical attribute associated with life. Kristian Peters. Cells from the moss Plagiomnium affine with visible chloroplasts, organelles that conduct photosynthesis by capturing sunlight.“You start with a random clump of atoms, and if you shine light on it for long enough, it should not be so surprising that you get a plant,” England said. England’s theory is meant to underlie, rather than replace, Darwin’s theory of evolution by natural selection, which provides a powerful description of life at the level of genes and populations. The “big hope” is that he has identified the underlying physical principle driving the origin and evolution of life, Grosberg said.“Jeremy is just about the brightest young scientist I ever came across,” said Attila Szabo, a biophysicist in the Laboratory of Chemical Physics at the National Institutes of Health who corresponded with England about his theory after meeting him at a conference. It is his interpretation — that his formula represents the driving force behind a class of phenomena in nature that includes life — that remains unproven. But already, there are ideas about how to test that interpretation in the lab.“He’s trying something radically different,” said Mara Prentiss, a professor of physics at Harvard who is contemplating such an experiment after learning about England’s work. Right or wrong, it’s going to be very much worth the investigation.”Courtesy of Jeremy England. A computer simulation by Jeremy England and colleagues shows a system of particles confined inside a viscous fluid in which the turquoise particles are driven by an oscillating force. Over time (from top to bottom), the force triggers the formation of more bonds among the particles. At the heart of England’s idea is the second law of thermodynamics, also known as the law of increasing entropy or the “arrow of time.” Hot things cool down, gas diffuses through air, eggs scramble but never spontaneously unscramble; in short, energy tends to disperse or spread out as time progresses. Entropy is a measure of this tendency, quantifying how dispersed the energy is among the particles in a system, and how diffuse those particles are throughout space. It increases as a simple matter of probability: There are more ways for energy to be spread out than for it to be concentrated. Thus, as particles in a system move around and interact, they will, through sheer chance, tend to adopt configurations in which the energy is spread out. Eventually, the system arrives at a state of maximum entropy called “thermodynamic equilibrium,” in which energy is uniformly distributed. A cup of coffee and the room it sits in become the same temperature, for example. As long as the cup and the room are left alone, this process is irreversible. The coffee never spontaneously heats up again because the odds are overwhelmingly stacked against so much of the room’s energy randomly concentrating in its atoms. Although entropy must increase over time in an isolated or “closed” system, an “open” system can keep its entropy low — that is, divide energy unevenly among its atoms — by greatly increasing the entropy of its surroundings. In his influential 1. What Is Life?” the eminent quantum physicist Erwin Schr. A plant, for example, absorbs extremely energetic sunlight, uses it to build sugars, and ejects infrared light, a much less concentrated form of energy. The overall entropy of the universe increases during photosynthesis as the sunlight dissipates, even as the plant prevents itself from decaying by maintaining an orderly internal structure. Life does not violate the second law of thermodynamics, but until recently, physicists were unable to use thermodynamics to explain why it should arise in the first place. In the 1. 96. 0s, the Belgian physicist Ilya Prigogine made progress on predicting the behavior of open systems weakly driven by external energy sources (for which he won the 1. Nobel Prize in chemistry). But the behavior of systems that are far from equilibrium, which are connected to the outside environment and strongly driven by external sources of energy, could not be predicted. David Kaplan, Tom Hurwitz, Richard Fleming, and Tom Mc. Namara for Quanta Magazine; music by Podington Bear. Video: David Kaplan explains how the law of increasing entropy could drive random bits of matter into the stable, orderly structures of life. Jarzynski and Crooks showed that the entropy produced by a thermodynamic process, such as the cooling of a cup of coffee, corresponds to a simple ratio: the probability that the atoms will undergo that process divided by their probability of undergoing the reverse process (that is, spontaneously interacting in such a way that the coffee warms up). As entropy production increases, so does this ratio: A system’s behavior becomes more and more “irreversible.” The simple yet rigorous formula could in principle be applied to any thermodynamic process, no matter how fast or far from equilibrium. England, who is trained in both biochemistry and physics, started his own lab at MIT two years ago and decided to apply the new knowledge of statistical physics to biology. Using Jarzynski and Crooks’ formulation, he derived a generalization of the second law of thermodynamics that holds for systems of particles with certain characteristics: The systems are strongly driven by an external energy source such as an electromagnetic wave, and they can dump heat into a surrounding bath. This class of systems includes all living things. England then determined how such systems tend to evolve over time as they increase their irreversibility. The finding makes intuitive sense: Particles tend to dissipate more energy when they resonate with a driving force, or move in the direction it is pushing them, and they are more likely to move in that direction than any other at any given moment.“This means clumps of atoms surrounded by a bath at some temperature, like the atmosphere or the ocean, should tend over time to arrange themselves to resonate better and better with the sources of mechanical, electromagnetic or chemical work in their environments,” England explained.

Self- Replicating Sphere Clusters: According to new research at Harvard, coating the surfaces of microspheres can cause them to spontaneously assemble into a chosen structure, such as a polytetrahedron (red), which then triggers nearby spheres into forming an identical structure. Self- replication (or reproduction, in biological terms), the process that drives the evolution of life on Earth, is one such mechanism by which a system might dissipate an increasing amount of energy over time. As England put it, “A great way of dissipating more is to make more copies of yourself.” In a September paper in the Journal of Chemical Physics, he reported the theoretical minimum amount of dissipation that can occur during the self- replication of RNA molecules and bacterial cells, and showed that it is very close to the actual amounts these systems dissipate when replicating. He also showed that RNA, the nucleic acid that many scientists believe served as the precursor to DNA- based life, is a particularly cheap building material. Once RNA arose, he argues, its “Darwinian takeover” was perhaps not surprising. The chemistry of the primordial soup, random mutations, geography, catastrophic events and countless other factors have contributed to the fine details of Earth’s diverse flora and fauna. But according to England’s theory, the underlying principle driving the whole process is dissipation- driven adaptation of matter. This principle would apply to inanimate matter as well. According to new research led by Philip Marcus of the University of California, Berkeley, and reported in Physical Review Letters in August, vortices in turbulent fluids spontaneously replicate themselves by drawing energy from shear in the surrounding fluid. And in a paper appearing online this week in Proceedings of the National Academy of Sciences, Michael Brenner, a professor of applied mathematics and physics at Harvard, and his collaborators present theoretical models and simulations of microstructures that self- replicate. These clusters of specially coated microspheres dissipate energy by roping nearby spheres into forming identical clusters. A plant, for example, is much better at capturing and routing solar energy through itself than an unstructured heap of carbon atoms. Thus, England argues that under certain conditions, matter will spontaneously self- organize. This tendency could account for the internal order of living things and of many inanimate structures as well.
