Could thermodynamic fluctuations have led to the origins of life

first_imgBrogioli suggests that this drift represents an early form of evolution that took place before membranes began to enclose chemical systems; after this time, the membranes would have assumed responsibility for defining entities in competition with one another, allowing selection to take place. If thermodynamic fluctuations did play the role of selection in early life, it would overcome the problem of requiring replicating chemicals and the membranes that enclose them to emerge simultaneously.In his paper, Brogioli looks at replication from a kinetics perspective, in which the kinetic counterpart of the inheritance of mutations is the presence of multiple stationary states, i.e., different lines of mutations can be present simultaneously, and their offspring inherit mutations. He shows that chemical systems that can pass mutations on to offspring can be thought of as systems with multiple stationary states, thus having the property of chemical marginal stability. These systems differ from a simple “self-catalytic” system (e.g., a purely chemical system) that merely produces offspring without transmitting mutations; the kinetic counterpart would be initial states that all lead to only one stationary state. As an analogy of a marginally stable system, Brogioli considers the mechanical example of a marble on a flat surface, where any point on the surface is a stationary point. If the marble is disturbed, it reaches a different stationary point rather than returning to its original position, since there is no restoring force. Likewise, spontaneous concentration fluctuations can enable a chemical system to inherit a variety of mutations from its parent system, and any of these mutations can be considered stable.Brogioli discovered the drift motion by mathematically studying the thermodynamic fluctuations over time. He found that, if two replicases R1 and R2 are present, the most efficient replicase, say R2, begins increasing in number and becomes dominant. In volumes with a higher concentration of R2, more replications will occur, and a larger fraction of them will be R2. Afterward, an even more efficient replicase can arise due to random mutations, and its concentration will increase, and so on.At the moment, the drift has been confirmed only by numerical calculations, and must be regarded as still theoretical. Brogioli notes that most chemical systems that have a replicase do not possess chemical marginal stability, and therefore are not affected by thermodynamic fluctuations. However, his study shows that the existence of a chemical system that is marginally stable and can undergo spontaneous evolution is possible. Investigating this theory further could have extremely important revelations. The demonstration of a marginally stable chemical system in the lab would not only be the first experiment in which a chemical system undergoes spontaneous evolution, but also the first in vitro model of a chemical reaction that leads to life.”Currently, no replicase that can self-sustain its replication has been created, but replication of RNA polymers can be obtained by ligation of short oligonucleotides,” Brogioli said. “This is a way [to find a chemical system could have marginal stability]. Another possibility is to create a more abstract system, in which replication is accomplished by an enzyme, and the activity of the enzyme is affected by the presence of one of the replicated polymers. Obviously, this is only a proof of principle of marginal stability and evolutionary drift, but not a realistic reproduction of the origin of life. The most interesting possibility is to consider the reactions proposed by the metabolism-first theories. In those theories, no replicating polymer was involved in abiogenesis, but only small molecules constituting some kind of metabolic network. The target is to find a very simple reaction that can be marginally stable.” (Left) Self-catalysis vs. (right) replication with inheritance in terms of kinetics: In the case of self-catalysis, all the initial states eventually lead to the same stationary state. In the case of replication with inheritance, the initial states lead to different stationary states on the stationary-state curve. The blue arrows show that the motion along the stationary-state curve is a drift pointing toward the increase of the most active replicase, R2.

In the field of abiogenesis, scientists are currently investigating several ways in which life could have arisen from non-living matter. Generally, any theory of abiogenesis should account for two important aspects of life: replication (the ability to transmit mutations to offspring) and metabolism (the chemical reactions required for vital activities such as breaking down food). Although these two characteristics help to provide a working definition of life, more recently scientists have emphasized the importance of another key feature required for Darwinian evolution: selection, or the replication of mutations that provide an evolutionary advantage.

(2010, August 16) retrieved 18 August 2019 from https://phys.org/news/2010-08-thermodynamic-fluctuations-life.html Explore further “The basic problem of abiogenesis is finding the first living entity that generated from non-living matter,” Doriano Brogioli, a physicist from the University of Milan-Bicocca, told PhysOrg.com. “But what is the definition of life: is it replication, or metabolism, or simply self-catalysis? I think that it is not simply a matter of definition: what is necessary is ‘evolution,’ even if the entity that undergoes (or performs) evolution is not a classical living entity. After evolution starts, it can reach whatever complex structures: from a cell, evolution creates trees, whales, birds, ants, and all the prodigious current living world.”Purely chemical systems may possess the ability to replicate and metabolize, but scientists have found that chemical systems by themselves do not undergo selection; more active molecules are not replicated more than others, and useful individual mutations are not inherited by the offspring. Therefore, researchers have suggested that some kind of physical process is likely required to introduce competition among chemical systems and generate the selective pressure required for evolution. “Three features are needed for evolution: inheritance, mutation and selection,” Brogioli said. “Single molecules can replicate other molecules, including other copies of themselves, and can undergo mutations. But in a solution with replicases, each replicase replicates whatever it finds, including non-active molecules or less active replicases. Selection is not active. The reason is that (traditional) chemistry favors selfish molecules: the molecule that is more able to be replicated increases its concentration. In order for selection to take place, there must be a physical process. Confination due to membranes is the current way used by living organisms. But it is hard to believe that a complex structure like a cell can form spontaneously, since the replicating polymers must form together with the membranes themselves. This problem is found in all the theories of abiogenesis, including the RNA-world and the metabolism-first theories.”Brogioli has taken a unique approach to satisfying the requirement for selection by proposing that the answer may lie in thermodynamic fluctuations. These fluctuations, which are changes in the number of molecules in a given volume due to thermal motions, may allow selection to become effective, leading to the increase in molecules having an evolutionary advantage. By investigating some chemical systems that possess a feature that he calls “chemical marginal stability,” Brogioli has shown that thermodynamic fluctuations induce not only a random walk, but a drift directed toward increasing replication efficiency.

Have we reached peak travel

first_img © 2010 PhysOrg.com Ridesharing can be made into more attractive cost-saver, study shows Explore further The study’s authors, Lee Schipper of the University of California, Berkeley, and Stanford University and Adam Millard-Ball, a doctoral candidate at Stanford University, analyzed travel trends from the US, the UK, Canada, Sweden, France, Germany, Japan, and Australia from 1970 through 2008. For each country, they plotted the distance traveled per capita per year by car, pickup truck, bus, plane, train, light rail, streetcar, and subway, and compared it to the country’s gross domestic product per capita.They found a correlation between rising prosperity and passenger travel from 1970 to 2003, after which passenger travel stopped growing (while GDP per capita continued to rise). At this peak travel period, GDP per capita was $37,000 in the US and between $25,000 and $30,000 in the other seven countries. During the past few years, motorized travel in the US has plateaued at around 26,000 km/year per person, 10,000 km/year per person in Japan, and between 13,000 and 17,000 km/year per person in the other six countries. (See above graph.)“Since 2003, motorized travel demand has leveled out or even declined in most of the countries studied, and travel in private vehicles has declined,” the authors wrote in their study. “Car ownership has continued to rise, but these cars are being driven less.”The researchers speculated that several factors have contributed to the apparent peak in passenger travel. One factor is saturation in vehicle ownership: in the US, there are about 700 cars per 1,000 people (which is more cars than licensed drivers), and about 500 cars per 1,000 people in most of the other countries. Basically, everyone who wants to drive, drives. Since 2007, car ownership in the US has declined due to the recession. Another limiting factor is time: people already spend an average of 1.1 hours per day traveling, and speed limits for the large part remain fixed. Other factors include high gas prices and an aging population that doesn’t commute.The researchers think that the biggest factor of the travel plateau may be traffic congestion. As Schipper said in an interview with Miller-McCune, “My basic thesis is, ‘There ain’t room on the road.’ You can’t move in Jakarta or Bangkok or any large city in Latin America or in any city in the wealthy part of China. I think Manila takes the prize. Yes, fuel economy is really important, and yes, hybrid cars will help. But even a car that generates no CO2 still generates a traffic problem. Sadly, what is going to restrain car use the most is that you can’t move.”Perhaps the biggest advantage of peak travel is that, if passenger travel continues to stay the same while vehicles become more fuel-efficient, then reducing transportation emissions may not be as daunting as previously thought. Today, the average American car uses a third less fuel per mile than in 1973, despite consumer demand for larger vehicles.Although the researchers note that their results are not conclusive and further research is needed, they conclude that the assumption that travel demand will continue to rise should be treated with caution. (PhysOrg.com) — Since the 1970s, passenger travel by vehicles and airplanes has grown rapidly in industrialized countries, and the International Energy Agency has predicted steady, though slower, travel growth until 2030 and beyond. However, a new study of eight industrialized countries has shown that passenger travel seems to have peaked in the early 2000s, just before the recent rise in fuel prices. The results suggest that demand for travel has reached a saturation point, which could mean that future projections of carbon dioxide emissions and fuel demand could be lower than previously thought.

Researchers build fully mechanical phonon laser

Lett. 110, 127202 (2013) DOI:10.1103/PhysRevLett.110.127202AbstractAn electromechanical resonator harboring an atomlike spectrum of discrete mechanical vibrations, namely, phonon modes, has been developed. A purely mechanical three-mode system becomes available in the electromechanical atom in which the energy difference of the two higher modes is resonant with a long-lived lower mode. Our measurements reveal that even an incoherent input into the higher mode results in coherent emission in the lower mode that exhibits all the hallmarks of phonon lasing in a process that is reminiscent of Brillouin lasing. Journal information: Physical Review Letters Citation: Researchers build fully mechanical phonon laser (2013, March 19) retrieved 18 August 2019 from https://phys.org/news/2013-03-fully-mechanical-phonon-laser.html Quantum leap for phonon lasers The world has grown accustomed to lasers, they’re a part of modern life, from DVD players to cash registers at the grocery store—lasers are everywhere. One thing they all have in common, is that they are based on photon emissions. There are other kinds of similar devices, of course, such as masers, which are based on microwave radiation, but they are not as well known. More lately, research has focused on lasers based on sound, which would emit phonons (lattice vibrations) instead of photons, an idea that’s been thrown around for several years, but hasn’t gotten much traction because the uses for such a laser are still unclear.Back in 2010 a team of researchers succeeded in building a phonon laser (or phaser, as some have taken to calling it) but it relied on the use of an optical laser. In this new effort, the research team has built a phonon laser that is purely mechanical, which the team says, should make it easier to implement in other systems should a reason for doing so be found.Photon lasers work by exciting electrons in a crystal or gas, then allowing them to revert to a more relaxed state. When they do so, a certain wavelength of light is released which is focused using mirrors.To build their phonon laser, the team followed the same basic design—a mechanical oscillator excites some amount of phonons, which are then allowed to revert back to a relaxed state. But the energy is still in the system—it causes the device to vibrate at a desired frequency within a very narrow wavelength, making it a lasing device. The entire laser has been etched onto a single integrated circuit.While researchers still aren’t clear to what purpose such a laser might be put, especially in light of the fact that phonons require a transmission medium to work, that hasn’t stopped them from proceeding. When the photon laser was first developed, no one knew what to do with it either. The researchers suggest that phonon lasers might be used to build a tiny clock, or as part of ultrasound machines or even as a very highly accurate measuring device.center_img (Phys.org) —Researchers working at Japan’s NTT Basic Research Laboratories have successfully built an all mechanical phonon laser.

Researchers attempt to uncover the origins of waters unusual properties

first_imgThe proposed pressure-temperature (P-T) phase diagram shows that, below a critical point, water is either in the high-density structure or in the low-density structure. However, above the critical point in a funnel-like region, water is constantly fluctuating between these two structures, and these structural fluctuations are what give rise to many of water’s anomalous properties. Credit: Nilsson and Pettersson. Nature Communications. More information: Anders Nilsson and Lars G.M. Pettersson. “The structural origin of anomalous properties of liquid water.” Nature Communications. DOI: 10.1038/ncomms9998 Explore further Outside of the funnel-like region, water stops behaving anomalously and begins behaving more like other liquids. In these regions, water’s structure is homogeneous, existing as only the low-density structure below the funnel-like region and only the high-density structure above the funnel-like region. While the new paper combines many years of data into one cohesive picture, many questions still remain. One unanswered question, for instance, is why does water’s anomalous region occur at the same temperatures and pressures that sustain life? It seems likely that water’s anomalous region served to place constraints on the conditions required for life to exist. A better understanding of this overlap could have implications for understanding life on a fundamental level.Many other questions also require further investigation. The researchers explain that their proposed interpretation is a very simple picture, and it does not tell the exact degree of heterogeneity in water in the anomalous region, nor does it describe the nature of the boundaries between the spatially separated fluctuating regions. Another area of investigation that has challenged researchers is the so-called “no-man’s land” region, which refers to the possibility of liquid water at temperatures below 232 K (-42 °C and -42 °F) but above 150 K (-123 °C, -189 °F). It’s extremely challenging to cool liquid water to these cold temperatures quickly enough so that it can be probed, even for a moment, before it turns to solid ice. In 2014, scientists successfully cooled liquid water to 5 K below no-man’s land and measured its structure using an X-ray laser—the Linac Coherent Light Source at the SLAC National Accelerator Laboratory. Experiments like these are needed to answer the question of whether water can exist in a liquid state in this region, which would help complete the P-T phase diagram.In the future, the researchers plan to investigate how water’s structural fluctuations contribute to other intriguing phenomena.”We will focus on using X-ray lasers to probe the supercooled regime and search for the liquid-liquid transition and second critical point,” Nilsson said. “We are also developing probe dynamics using the femtosecond time resolution of the X-ray lasers, allowing eventually to probe the dynamics of these structural fluctuations. There might be some intricate coupling of time and space on various length and time scales that are still unknown. “We hope that others will also bring other techniques involving time resolved two-dimensional IR spectroscopy, NMR and neutron scattering to further investigate water along these lines. Also further refinement of theoretical approaches to both calculate experimental observables but also to simulate water.” Evidence for solid-liquid critical points of water in carbon nanotubes Journal information: Nature Communications (Phys.org)—In many ways, water behaves very differently than other liquids do, and with important consequences: It’s widely thought that water’s unusual properties were essential for the development of life on Earth. One prime example is the fact that ice floats. Unlike other substances, frozen water is less dense than liquid water, and this anomaly allows fish and other aquatic lifeforms to survive in the water under a frozen layer of protective ice during cold periods. Water also has a high heat capacity, meaning it can absorb and release a large amount of heat while undergoing very little change in temperature. This property helps many living organisms maintain a relatively stable body temperature, and it also provides a pleasant climate in Europe due to the warm Gulf Stream current. © 2016 Phys.org Citation: Researchers attempt to uncover the origins of water’s unusual properties (2016, January 12) retrieved 18 August 2019 from https://phys.org/news/2016-01-uncover-unusual-properties.html It’s widely known that water’s anomalous properties are related to its hydrogen bonds, which cause liquid water to arrange itself in a highly ordered way because of the attraction between the hydrogen atoms in one water molecule and the oxygen atoms in adjacent molecules. However, researchers do not completely understand how water’s unique hydrogen-bonded structure leads to its anomalous properties. In a review paper published in Nature Communications, physicists Anders Nilsson and Lars G.M. Pettersson from Stockholm University have pulled together the results from dozens of papers published over the past several years that have investigated water’s molecular structure, often with the help of cutting-edge experimental tools and simulations. In their interpretation of the data, the researchers have proposed a picture of water in which its unique properties arise from its heterogeneous structure.The researchers propose that, in the pressure (P) and temperature (T) region where water exhibits its anomalous behaviors (the funnel-like region in the P-T phase diagram above), water coexists in two different types of structures: a highly ordered, low-density structure with strong hydrogen bonds, and a somewhat smashed, high-density structure with distorted hydrogen bonds. The origins of water’s anomalous properties arise because these two types of structures are constantly fluctuating between one another in this heterogeneous phase, resulting in many small spatially separated regions of different structures.”It is the fluctuations between high-density liquid and low-density liquid that give rise to the anomalous properties,” Nilsson told Phys.org.Take water’s large heat capacity, for instance. As Nilsson explained, heat capacity is related to entropy fluctuations, and entropy is in turn related to the number of possible ways the available energy can be distributed in the system. Fluctuations between the low- and high-density local structures increase the magnitude of the entropy fluctuations and, consequently, the heat capacity. This document is subject to copyright.

New study takes a different approach to showing human activity causing earthquakes

first_img © 2017 Phys.org Journal information: Science Advances Fracking, extracting natural gas using hydraulic fracturing, and other techniques, have been in the news a lot of late. On the one hand, it has been credited with helping the U.S. become less dependent on foreign oil. But on the other hand, more studies are finding that in addition to harming the environment, the practice appears to be causing small earthquakes. It should be noted that it is not the actual fracking that is believed to cause earthquakes, it is the practice of forcing the dirty water left over from the process back into the ground afterwards that appears to cause the problems—it loosens material around underground faults.There is little doubt that more earthquakes have been occurring in parts of the U.S. since fracking began, but less certain is whether fracking is the cause. The strongest proof to date has been the location of the upswing in small earthquakes around areas where fracking is conducted. In this new effort, the researchers sought to take a more scientific approach to settling the matter—they used the same technology that the oil companies use to find underground deposits of oil and gas—high-resolution seismic reflection imaging. But instead of looking for oil or gas, the researchers looked for deformed faults beneath the ground in the Forth Worth basin. They compared seismic readings in Texas with those from sites in a northern part of Mississippi with a history of small quakes going back to the 1800s, well before fracking began.The researchers report that their readings showed that the most recent natural fault activity beneath the Fort Worth basin was approximately 70 million years ago. That meant that the team was unable to find any natural cause for the recent quakes, leaving fracking as the only possible culprit.

Discriminating between natural versus induced seismicity from long-term deformation history of intraplate faults, Science Advances (2017). DOI: 10.1126/sciadv.1701593AbstractTo assess whether recent seismicity is induced by human activity or is of natural origin, we analyze fault displacements on high-resolution seismic reflection profiles for two regions in the central United States (CUS): the Fort Worth Basin (FWB) of Texas and the northern Mississippi embayment (NME). Since 2009, earthquake activity in the CUS has increased markedly, and numerous publications suggest that this increase is primarily due to induced earthquakes caused by deep-well injection of wastewater, both flowback water from hydrofracturing operations and produced water accompanying hydrocarbon production. Alternatively, some argue that these earthquakes are natural and that the seismicity increase is a normal variation that occurs over millions of years. Our analysis shows that within the NME, faults deform both Quaternary alluvium and underlying sediments dating from Paleozoic through Tertiary, with displacement increasing with geologic unit age, documenting a long history of natural activity. In the FWB, a region of ongoing wastewater injection, basement faults show deformation of the Proterozoic and Paleozoic units, but little or no deformation of younger strata. Specifically, vertical displacements in the post-Pennsylvanian formations, if any, are below the resolution (~15 m) of the seismic data, far less than expected had these faults accumulated deformation over millions of years. Our results support the assertion that recent FWB earthquakes are of induced origin; this conclusion is entirely independent of analyses correlating seismicity and wastewater injection practices. To our knowledge, this is the first study to discriminate natural and induced seismicity using classical structural geology analysis techniques.center_img Pennsylvania correlates natural gas fracking with quakes Post-2008 seismicity rate change in the central United States.

Violence Returns To Hong Kong As Police Fire T

first_imgViolence Returns To Hong Kong As Police Fire Tear Gas And… by NPR News Gabriela Saldivia 8.24.19 4:02pm After a stretch of relative peace in Hong Kong, a standoff between protesters and riot police became violent again on Saturday.Police fired tear gas after pro-democracy demonstrators blocked roads with barricades made of bamboo sticks and hurled bricks, in the district of Kwun Tong.In a statement, police said protesters paralyzed traffic and affected emergency services in the area near a police station.Protesters tore down and dismantled “smart lampposts” out of a fear that they contain high-tech cameras and facial recognition software used for surveillance by authorities in China.Some used an electric saw, attempting to slice through the bottom of a lamppost, while others tied a rope around it to successfully bring it crashing to the ground, The Associated Press reported.The government in Hong Kong insists that the lampposts only collect data on weather, air quality and traffic, according to the AP. There are plans to install about 400 of these smart lampposts over a three-year period, according to a government report. The latest skirmish marked the 12th straight weekend of demonstrations in Hong Kong and ended nearly two weeks of relative calm, according to the AP.Just a day before, thousands of Hong Kongers held hands and formed human chains, in a peaceful bid to gain support from the international community, NPR’s Anthony Kuhn reported.On Saturday, Hong Kong Chief Executive Carrie Lam expressed a desire to open a dialogue on Facebook.”I don’t expect that dialogue will be able to easily untangle this knot, stop the demonstrations or provide a solution to the problem,” Lam wrote. “But continuing to fight is not a way out.””After more than two months, everyone is tired. Can we sit down and talk about it?” she wrote.Just a few hours later, protests in Kwun Tong turned violent, according to The New York Times.The protests in Hong Kong originally began in June over a bill that would have allowed some extraditions of Hong Kong residents to mainland China. The bill sparked a backlash among those who saw it as a violation of the “one country, two systems” agreement that was formed in 1997 when Hong Kong was returned to China from BritainThe bill has since been shelved, but it’s not formally dead. Hong Kong’s government indefinitely suspended the legislation in June but hasn’t withdrawn it entirely. The demands from the movement have since expanded and now include calls to investigate excessive police violence during the demonstrations and a more transparent and open government.Also on Saturday, Simon Cheng, a worker from the British Consulate in Hong Kong, was released after being detained in mainland China. Cheng disappeared on a business trip in mainland China two weeks ago amid the rising tensions between Beijing and London.It wasn’t immediately clear whether Cheng’s detention had anything to do with Britain’s support of the pro-democracy protests, NPR’s Scott Neuman reported.Copyright 2019 NPR.

Cavs will beat Boston despite getting blown out in Game 1

first_imgCavs will beat Boston despite getting blown out in Game 1The Cavs got drilled by the Celtics in Game 1 in Boston, and following the game LeBron James said he wasn’t overly concerned about it. Colin thinks the game just meant more to the young Celtics, many of whom who grew up idolizing LeBron, and it showed with an emotional performance before a hyped up home crowd.James has been through enough playoff battles to look at the bigger picture of the series without panicking over a bad Game 1 loss. He’s been here before. He still predicts the Cavs will win the series. LeBron to the Rockets would be the best scenario for the NBA The Rockets will take on the Warriors in Game 1 of the Western Conference Finals tonight, and Colin thinks a Houston series loss would make LeBron to the Rockets a real possibility.He thinks LeBron would be attracted to the Rockets because he could be the piece that helps them finally beat the Warriors and help them win a title. It would be the third franchise LeBron has led to a title, which would help him in his career comparison to Michael Jordan in the never-ending G.O.A.T. debate. It would also help create a counter balance to the Warriors domination in the West, and allow the Celtics and Sixers to grow as rivals in the East.

Video Gaming Craze

first_imgApril 1, 2006 Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 3 min read Growing a business sometimes requires thinking outside the box. As poker mania sweeps across the country, mutterings of Two Fat Ladies and Big Slick buzz around felt-topped kitchen tables. But as friends and acquaintances battle for tournament supremacy, pay attention, because the players in the loser’s lounge often gather around a video-game console. When the dust finally settles around poker hysteria, video games are in the perfect position to fill the gaming void.Jason Della Rocca, executive director for the International Game Developers Association, says the gaming industry has already arrived. “It’s this neverending tidal wave,” says Della Rocca. “It just keeps collecting mass.”According to the Entertainment Software Association, 50 percent of all Americans-and 75 percent of heads of households-play video games. The games have similarities to poker that are helping them reach the mainstream, in the same way poker has: Both video games and poker are blind to gender, age, social environment and physical abilities. Both boast professionals and have a media following. Just as poker birthed heaps of accessory opportunities for entrepreneurs, so have video games-perhaps more so. The video-game market continues to innovate with products like exergames, which encourage physical activity, and Nintendo’s new physically responsive controller (for example, gamers playing a fishing game use the controller as if they were actually casting a reel). And neither is a fad-the average gamer has been playing for 12 years, according to the ESA. While poker has been the recent beneficiary of widespread attention, it’s been a part of American folklore since Wild Bill Hickok was shot in 1876 holding a dead man’s hand.Della Rocca notes that many gamers are beginning to recognize that not just teenagers and young men, but their moms, wives and girlfriends are interested in games. “Those who are not really part of the gamer culture are starting to wake up to this,” he says.As nongamers begin paying attention to the industry, entrepreneurs can benefit by pushing in their chips now with opportunities in service, development, accessories and more. Entrepreneurial niches exist in advergames, mobile games and “serious” games, where simulation or learning is the goal. In addition to the much-anticipated arrival of Microsoft’s Xbox 360 last year, this year marks the rollout of Sony’s Playstation 3 and Nintendo’s Revolution. Della Rocca says the marketing and promotion dollars invested in these launches should definitely attract even more mainstream attention to video games. The wave is only getting bigger, so don’t wait until the River to jump in. This story appears in the April 2006 issue of Entrepreneur. Subscribe » Register Now »last_img read more

Selling Computers and Accessories on eBay

first_img Note: This article was excerpted from How to Sell Computers and Accessories on eBay, which is available from EntrepreneurPress.com.Computers and computer accessories are some of the best-selling and most reliably profitable items on eBay. Thousands of people visit eBay every day to browse and shop for new PCs, printers, networking components, cables, monitors and many other computer-related items. Many savvy eBay sellers have already recognized and capitalized on eBay’s large and hungry market for everything computer related. With some research, foresight and careful planning, you can join their ranks.Though selling on eBay is a great way to earn money, it is not a get-rich-quick miracle. Care must be taken when conducting all your transactions and dealing with bidders. eBay’s feedback system is a double-edged sword. It will, at once, boast to the world how great a seller you are, while revealing to the world exactly where you are lagging behind. It takes a lot of work to make and keep buyers happy. If you’ve ever had a job that deals directly with the public, then you know this already. If you do not have the time or interest to devote to taking care of the details of doing business, such as getting packages to the shipping store on time in the middle of a snowstorm, or answering buyer e-mails after a long day of crunching numbers in your cubicle, then selling on eBay is not for you. Your feedback score will suffer, and soon buyers will shy away from your listings. However, if you’re ready and excited for the possibilities eBay presents, then you will have a rewarding and profitable experience.PowerSelling vs. Selling as a HobbyThe first step in selling on eBay is to decide your commitment level to this endeavor. There are two levels of commitment when discussing selling on eBay: hobby seller and PowerSeller. The hobby seller sells casually for extra cash when she finds time in her schedule. The PowerSeller has made selling online her career. The tips found in How to Sell Computers and Accessories on eBay will help both the hobby seller and PowerSeller become more successful, but the initial planning for these two commitment levels is decidedly different. The differences are discussed throughout the book, but for now just think carefully about whether you want to depend on selling computers on eBay as your only income, or if you’d like for it to supplement what you’re already earning elsewhere.Both hobby selling and PowerSelling can be fun, exciting and lucrative. If you’re not sure where to begin, plan to start small and grow over time. It’s much easier to start selling as a hobby to supplement your job than it is to start selling full time and then grovel for your job back if you decide this career isn’t for you.Assessing the CompetitionOf all the possible items to sell, selling computers is a smart choice. Technology is growing and evolving at such a rapid rate that there is near constant demand for more products. However, because these items are immensely popular with bidders, they are also immensely popular with eBay sellers, which means you’ll find plenty of competition in this category. Be aware that if you plan to reach the coveted PowerSeller status, you have your work cut out for you. Many PowerSellers are busy not only keeping a careful eye on their own businesses, but they also have learned to keep a strict eye on their competition-you.The bright side of having a lot of competition is that it provides a lot of opportunities for market research. This is where you begin your journey to becoming a successful eBay computer seller. Know your competition, both on eBay and off, including brick-and-mortar retailers like Best Buy, Wal-Mart and Apple, online stores and local computer shops. What are their strengths? More importantly, what are their weaknesses? If your competition sells on eBay, find and study their product listings. Are they attractive, complete, and clear? Read their customer feedback comments. Are buyers complaining about slow shipping, inaccurate descriptions, or poor customer service? Find these faults, and make it your goal to provide better service in these areas.You’ll find when researching your competition that buyers have countless options for where to buy their computers and computer accessories. It is often impossible to compete with all these sellers on price alone. There are sure to be larger sellers out there who can buy in such large bulk quantities that their per-item price drops significantly. One day, you will be able to do the same, but when you’re starting out, you should focus on competing on customer service, attractive and com¬plete eBay listings, and reliable shipping. You will soon build a feedback score that will attract the buyers you need to begin buying and selling items on par with the PowerSellers. Before you know it, you’ll be a PowerSeller yourself.The Tech-Trickle-DownThe computer market is still in its infancy. New, or first-generation, technology is being introduced nearly every day. Companies like Apple, Intel, and Sony are redefining the “cutting-edge” with seemingly every press conference they hold. This rapid development rate of new technologies and the premium price on those new technologies create a trickle-down effect. Large companies and power users buy the first-generation technology as soon as it becomes available to the public. This technology could be anything from new CPUs to faster hard drives to biometric scanners. Upon introduction, these new items fetch too high a price for the average user to buy and therefore comprise a limited segment of the market. But, inevitably, new technology is introduced that improves upon, and replaces, the previously latest and greatest technology, making it the new second generation. This second-generation equipment is now cheaper and more accessible to the average user. So the number of units sold actually increases to fill the large demand created by buyers who waited for the price to come down. Then, when new technologies are again introduced, this now third generation equipment is moved down the chain to users who don’t mind, or are oblivious to, old hardware. Think of third-generation hardware as the old ThinkPad sitting on your mother’s desk, or grandpop’s Apple IIe.You have an opportunity to sell at every step in the tech¬nology trickle-down process. Pre-order new technology before launch to capitalize on the high, post-launch demand. Watch the hot technology companies to find out when they are set to launch a new product and buy up the inventories of retailers selling off soon-to-be second-generation equipment to make room for the new first generation. Finally, sell off third-generation items at high-volume and rock-bottom prices to turn a profit. Seek new markets for old hardware, such as collectors, hobbyists, and young businesses.Meet a PowerSellerJohn Kreutzer is a Mac-fanatic.
