Marine technology inspired by dolphins speed

Since the days of Aristotle, humans have looked to dolphins with awe, envy and inspiration because of the marine animal’s speed and strength in the oceans. Swimming at speeds of up to 20 mph, the dolphin seems to defy nature’s laws. In fact, in the 1930s, the scientist James Gray thought that the power needed for the dolphin to swim at such speeds exceeded its available power nearly 10 times over, which is known as Gray’s paradox. To explain his paradox, Gray theorized that the water against the dolphin’s skin has layers that slide past each other and reduce drag, called “laminar boundary layers.” (It was previously assumed that the water against the skin was made of several mixed layers that increase drag, called “turbulent boundary layers.”) In actuality, no mechanisms have been demonstrated that maintain a completely laminar boundary layer for the dolphin.“While Gray may have missed the actual mechanism for the high swimming speed of dolphins, his focus on these extraordinary animals and their performance was not without merit,” scientist Frank Fish of West Chester University told PhysOrg.com. Fish, who has researched dolphin drag and propulsion for many years, recently published a review in Bioinspiration and Biomimetics examining the different mechanisms on drag reduction. “[Gray’s] focus on laminar and turbulent flows helped to define a large body of research on animals with consideration to their aquatic adaptations and energetics. Furthermore, because of Gray’s work, a whole new mechanism for drag reduction – compliant surfaces – was developed.”Today it’s common knowledge that Gray’s paradox had a few flawed assumptions: Gray calculated that dolphin musculature resembles that of humans, while in reality dolphin muscles can generate several times the power of human muscles. Also, Gray observed dolphins swimming at short sprints, but neglected to account for the greater power output generated by the type of muscle fiber (fast glycolytic) used for short bursts as opposed to the type of muscle fiber (slow oxidative) used for slow, sustained activity. Finally, Gray did not consider that the dolphin was using a passive drafting technique to swim at high speed. This document is subject to copyright.

According to Gray’s paradox, dolphins swim faster than they should be able to. Since Gray, scientists have discovered flaws in the details of the paradox, although some explanations of these creatures’ aquatic grace have proven to hold more water than others.center_img Hidden oil spill: New study contradicts owner’s claims Explore further Despite the flaws in Gray’s paradox, however, the dolphin still possesses superior swimming capabilities compared with technologies from nautical engineering. Throughout the past several decades, scientists have offered a plethora of ideas explaining how the dolphin actually swims as quickly as it does. In his review, Fish examines how these ideas reduce drag, which range from mechanisms for laminar boundary layer conditions (viscous damping and accelerated flow), strategically located skin ridges, skin shedding/secretions, skin heating and others. The two most significant reasons, Fish concludes, are not special mechanisms, but rather the streamlined body shape and behavioral mechanisms.“Dolphins are among the fastest of marine creatures,” said Fish. “That ability is powered by large muscles that are mechanically linked to an oscillatory pair of flukes, producing thrust with greater efficiency than conventional marine propellers.”A dolphin’s “fusiform” body shape – with its rounded front, maximum thickness at 34-45% of the body length, and slowly tapering tail – allows water to flow inseparably from the body until the tail region. This delayed separation results in a small wake and reduced drag. Further, the crescent design of the flippers, dorsal fin and tail (“flukes”) of the dolphin reduce drag and can also efficiently generate lift when needed.Because dolphins belong to the cetacean order, they are mammals that require oxygen. However, wave drag at the surface can reach five times the frictional drag for a dolphin at one-half a body length under water, so the animals use a breathing method called “porpoising.” While maintaining high speeds, a dolphin partakes in a series of rhythmic leaps to the surface, and scientists calculate that it takes less energy to leap at these speeds than to swim an equivalent distance underwater. A second behavioral mechanism that dolphins employ is gliding, a behavior which allows lung collapse and minimizes buoyancy when descending in deep water, conserving both energy and oxygen. Finally, young dolphins often utilize drafting by swimming below the mid-section of the mother, taking advantage of flow structure and energy savings of up to 60%.Fish concluded that although Gray’s laminar boundary layer may not have been demonstrated for dolphins, the explanation – along with some of the other proposed ideas – could still have technological applications. “The need to move more economically on or under the water will necessitate the development of better propulsive systems,” he said. “This will be more important as we further explore the recesses of the ocean, on this planet or others. We currently rely upon rotating propellers to move ships and boats, but these devices have a limited efficient speed range.”Fish predicted that the development of new hull designs, skin mechanics and propulsive systems may take advantage of nature’s swimming mechanisms. “Submarine and autonomous underwater vehicles (AUVs) may benefit from copying the body design of dolphins to enhance not just speed but also maneuverability,” said Fish. “The elastic structure of the dolphin skin and its underlying blubber may serve as a model for future wetsuits or competitive swim suits. The arrangement of fibers applied to competition suits will reduce drag from vibrations and folds produced by the swimming motions of human swimmers. Perhaps swimmers in the next Olympics will wear suits based on dolphins to break existing records.”Citation: Fish, Frank E. “The myth and reality of Gray’s paradox: implication of dolphin drag reduction for technology.” Bioinspiration and Biomimetics. 1 (2006) R17-R25.By Lisa Zyga, Copyright 2006 PhysOrg.com.

The tiny bulb contains an argon gas in the middle, as well as a component called a “puck.” The bulb is partially embedded in a dielectric material. When electrical energy is delivered to the puck, the puck acts like an electrical lens. It heats up the argon to a temperature of 6000 degrees Kelvin, and turns the gas into a plasma that gives off light. The plasma, whose 6000-degree temperature is similar to that of the surface of the sun, also emits a spectrum that looks very similar to the spectrum of sunlight.The plasma bulb uses 250 watts, and achieves around 140 lumens per watt, making it very bright and highly efficient. By comparison, conventional lightbulbs and high-end LEDs get around 15 and 70 lumens per watt, respectively. “A key advantage is that the energy is driven into the bulb without any electrodes, so you don’t need any electrical connections to get the energy into the bulb,” Luxim CEO Tony McGettigan explained to ZDNet. Luxim is using different versions of its electrode-less plasma technology to develop lighting for ultra-bright projection displays, retail and street lighting, microscope lighting, and various medical applications.More information: Luxim.com via: ZDNetlast_img read more

Shocking Environmental chemistry affects ferroelectric film polarity the same way electric voltage

first_img “Normally,” Stephenson continues, “voltage is applied to change the internal structure in ferroelectric materials. You can turn the crystal upside down from the internal point of view. We have shown, I think for the first time, that this can also be done chemically by changing the chemistry of the environment.” The results of the work, which includes scientists from Northern Illinois University and the University of Pennsylvania as well as Argonne, can be found in Physical Review Letters: “Reversible Chemical Switching of a Ferroelectric Film.”In order to test the process of chemical switching by changing the environment of the ferroelectric film, Stephenson and his colleagues varied the oxygen partial pressure. In situ x-ray scattering was used to “see” the changes in the polarization of the material. The specific ferroelectric material used for the experiment was lead titanate (PbTiO3). The group found that changing the oxygen pressure switched the polarization of the PbTiO3 film in much the same way as the conventional practice of using electrodes and voltage.The use of x-rays is important, since it allows scientists a peek at what is actually happening inside these materials. “The challenge has been to measure what is going on,” Stephenson admits. “With these thin films, external voltage measurements become more ambiguous. With our x-ray technique, we are able to watch the atomic-scale structure inside these systems.”“Up until now,” he continues, “we didn’t really think that the environment these ferroelectric materials were in could be just as important as the voltage applied. Fundamentally, we didn’t realize that extra oxygen or missing oxygen at the surface could produce an electric field big enough to affect properties.”This knowledge will become more important, Stephenson explains, as the demand for smaller devices made from new materials increases. Infrared and terahertz technology, controllable catalysts and chemistry applications on chips represent some of the areas that might benefit from a better knowledge of how switching works with PbTiO3 films. “Already there are ferroelectric materials used for non-volatile computer memory devices,” Stephenson points out. “But the holy grail of these is a memory element the size of an atom. As films get thinner, understanding the interfacial properties of these materials makes a difference. If the chemistry of the environment can change the polarization, we need to harness this to create new types of devices.”“The big picture is that we are trying to create new functional materials with interesting properties. We want to understand the way interfaces between different materials work. Ferroelectrics provide a model system where we can produce and measure large effects of the electric fields from the interfaces.”Additional information: Wang, et. al. “Reversible Chemical Switching of a Ferroelectric Film.” Physical Review Letters (2008).

Physicists create sonic black hole in the lab

first_img(PhysOrg.com) — Black holes get their name because they absorb all incoming light, and are so dense that none of that light can escape their event horizon. In a new study, scientists have created a sonic analogue of a black hole in the lab – that is, a sonic black hole in which sound waves rather than light waves are absorbed and cannot escape. The scientists hope that the short-lived sonic black hole could allow them to observe and study the elusive Hawking radiation that is predicted to be emitted by traditional black holes, which has so far been a very difficult task. Simulating black hole radiation with lasers More information: Oren Lahav, et al. “Realization of a Sonic Black Hole Analog in a Bose-Einstein Condensate.” Physical Review Letters 105, 240401 (2010). DOI:10.1103/PhysRevLett.105240401 The scientists, Oren Lahav and coauthors from the Technion-Israel Institute of Technology in Haifa, Israel, have published their study on the sonic black hole in a recent issue of Physical Review Letters.The researchers created the sonic black hole in a Bose-Einstein condensate made of 100,000 rubidium atoms slowed to their lowest quantum state in a magnetic trap. This cold cluster of atoms acts like a single, large quantum mechanical object. In order to transform this condensate into a sonic black hole, the scientists had to find a way to accelerate some of the condensate to supersonic speeds so that the condensate would contain some regions of supersonic flow and some regions of subsonic flow. The scientists achieved this acceleration by shining a large-diameter laser on the condensate in such a way as to create a steplike potential and a harmonic potential. When the condensate crosses the “step” in the steplike potential, the condensate accelerates to supersonic speeds. The scientists demonstrated that the condensate could accelerate to more than an order of magnitude faster than the speed of sound.“The greatest significance of our article is that we succeeded in overcoming the Landau critical velocity, which states that flow cannot exceed the speed of sound,” coauthor Jeff Steinhauer of the Technion-Israel Institute of Technology told PhysOrg.com. “Our experiment exceeds this limit for a finite period of time.”In this setup, the step marks the boundary between the supersonic and subsonic regions, which acts as the black hole’s event horizon. At this event horizon, the flow velocity of the condensate is exactly equal to the speed of sound. On the supersonic side of the step, the density of the condensate is much lower than that on the subsonic side. As the scientists explained, the low density corresponds to a higher flow velocity due to conservation of mass. In their experiments, they could maintain the black hole event horizon for at least 20 milliseconds before it became unstable.Similar to how a black hole traps photons, the supersonic region of the sonic black hole can trap phonons and a wide range of other Bogoliubov excitations with a wavelength of between 1.6 and 18 micrometers. Excitations with very short wavelengths can escape, and those with longer wavelengths cannot fit in the supersonic region in the first place. In the future, the scientists plan to use the sonic black hole to study Hawking radiation. As the physicist Stephen Hawking first predicted, black holes may emit a small amount of thermal radiation due to quantum effects. Losing this radiation can cause black holes to shrink and eventually evaporate completely. But so far, detecting this radiation has been very challenging.In order to observe Hawking radiation in the case of the sonic black hole, there are a few requirements, such as that the trapped excitations must have negative energy. The researchers verified this in simulations: When focusing two laser beams with slightly different frequencies onto the supersonic region of the condensate, the simulated condensate absorbed a photon from one beam and emitted a photon into the second beam, creating an excitation with negative energy. In the future, the sonic black hole may give scientists a glimpse of Hawking radiation. Explore further This document is subject to copyright.

A new fossil discovery of bones makes the 90-pound emperor penguin, thought to be the largest of all penguins, rather puny. Penguin-watching has become all the more fascinating in light of new observations from researchers about the penguin past. RT called its headline The Big Kiekowskii, and New Scientist referred to the mega-penguin. They were talking about the study that presents newly unearthed fossils. The title of their study is “New giant penguin bones from Antarctica: Systematic and paleobiological significance,” by Dr Carolina Acosta Hospitaleche and Marcelo Reguero. Antarctica was once home to the biggest species of penguin, ever—they were around 37 to 40 million years ago. Fossil deposits were excavated on Seymour Island, off the Antarctic peninsula. The researchers reckoned that this penguin was over six feet (2 meters) and weighed over 250 pounds (115 kilograms).The species is known as Palaeeudyptes klekowskii. How did these researchers know the penguin was so huge? They knew by way of the bones they discovered, indicating the penguin was the tallest and heaviest ever to walk the Earth. Detailing Acosta Hospitaleche’s work, New Scientist said, “Now she has uncovered two bigger bones. One is part of a wing, and the other is a tarsometatarsus, formed by the fusion of ankle and foot bones. The tarsometatarsus measures a record 9.1 centimeters. Based on the relative sizes of bones in penguin skeletons, Acosta Hospitaleche estimates P. klekowskii was 2.01 meters long from beak tip to toes.”The larger the penguin, the deeper it can dive. Also, the large the penguin, the longer it can remain underwater. The researchers reckoned this heavyweight P. klekowskii could have stayed down for 40 minutes, which indicates it was able to enjoy more time to hunt fish,Seymour Island is in the chain of islands around the tip of the Graham Land on the Antarctic Peninsula. Many fossils have been discovered on the island. According to The Guardian, the bones were found at the La Meseta formation, Seymour Island, which is part of the peninsula with a wide range and abundance of penguin bones. New Scientist noted that “This was a warmer region 40 million years ago, with a climate like that of present-day Tierra del Fuego, the islands at the southern tip of South America.” According to Acosta Hospitaleche, added New Scientist, this was “a wonderful time for penguins, when 10 to 14 species lived together along the Antarctic coast.” © 2014 Phys.org Citation: Klekowskii penguin takes size title away from emperor (2014, August 4) retrieved 18 August 2019 from https://phys.org/news/2014-08-klekowskii-penguin-size-title-emperor.html Explore furtherlast_img read more

Meanwhile, another team wondered if the Higgs boson was a piece of the matter-antimatter puzzle. They think the recently found particle might actually play a role in the apparent imbalance between matter and antimatter in the universe and want to design and run experiments at LHC to look into the possibility. Also, another team found the first direct evidence of a mysterious phase of matter that competes with high-temperature superconductivity—they’re calling it the “pseudogap,” and think it might be robbing superconcuctors of electrons preventing 100 percent efficiencies.

He says,‘I seriously don’t think changing genres proves anything. I write for myself and not for the market and I’m comfortable writing in any genre under various themes of tragedy, comedy, fear. I would rather prefer not being tagged as a genre-specific writer.’ Also Read – ‘Playing Jojo was emotionally exhausting’All the stories have an Indian connect.

He believes any ghost story collection is incomplete without touching upon the idea of possession, the merging of a secondary spirit with a human soul. Kazi wanted to retain  a strain of innocence in the story, hence the protagonist is a child and through her we see the world of the unknown and soon see her family also getting involved. Perhaps there is a hidden story of possession in every neighbourhood and readers can make the connection, irrespective of  their believers or sceptics.

Simply through the psyche and thought process of one single man who vows to ‘create’ his dream girl by cutting and stitching together the body parts of other girls, I tried to understand our deepest recesses.’He’s also a genre-hopper, evidently.

Kristi Yamaguchi wished Nancy Kerrigan luck on Dancing with the Stars by

first_img1992 Olympic figure skating gold medalist Kristi Yamaguchi took some time out of her day to wish her friend, and fellow Olympic figure skating alum, Nancy Kerrigan good luck during her upcoming appearance on Dancing with the Stars.Her word choice could have been better.Yamaguchi tweeted to Kerrigan to “break a leg” during her performance, which would be fine if Kerrigan hadn’t been famously knee-capped with a pipe after exiting a 1994 U.S Figure Skating Championship workout.So excited for you @NancyAKerrigan ! Can’t wait to see you grace that ballroom floor, break a leg! ??#DWTS— Kristi Yamaguchi (@kristiyamaguchi) March 20, 2017 Advertisement It was obviously an innocent mistake by Yamaguchi, and enough time has passed from the incident that we should all be able to have a chuckle over it.Don’t get any ideas, Tonya Harding.last_img read more

Kobe Unfazed by Injury Concerns While Dominating at Rucker Park After 2002

first_imgThe sports media debate machine is raging over Zion Williamson, and if he should shut it down at Duke and wait for the NBA, or finish out the season if he’s 100% healthy. The obvious concern for those advocating that he sit is that he could cost himself millions if he is seriously injured while playing for free, but there is evidence of big time ballers not worrying about getting hurt while not getting paid.In the summer of 2002, fresh off the Lakers three-peat, Kobe Bryant was at the top of the basketball world. That didn’t stop him from accepting an invitation to run at the legendary Rucker Park in New York and going into full Mamba mode. Injuries, schminjuries.If Zion continuing to play for another month in college has your heart racing, the sight of Kobe taking on all comers on the blacktop, in the rain, might take you out. Kobe doesn’t care for your injury concerns.last_img read more

And two years ago, the payment giant attempted to change how we use our phones when it introduced its PayPal Mobile app, which offers to transfer money from one person to another by bumping phones together. And though it would make sense for PayPal to continue its reign in payment innovations, the company appears to be the last to arrive at the mobile-payment party.Earlier this month, PayPal with a heaping helping of pomp, launched its mobile payment system PayPal Here, which runs on a person’s smartphone through a downloadable app and uses a small plastic reader to swipe cards. The company boasted last week that it signed up more than 1,000 new users per hour in its first day.Though PayPal remains a juggernaut in the online-payment space, the question is, is PayPal too late to make a dent with business customers?The new platform joins incumbent systems like Jack Dorsey’s Square, Intuit’s GoPayment, and North American Bancard’s Pay Anywhere, among others. Square, alone, claims more than a million users and merchants and a spokesperson says the company processes more than $4 billion annually. But, it’s a sector that’s growing, says Todd Ablowitz, founder of Double Diamond Group, LLC, a Centennial, Colo., payment systems consultancy. “The entrance of PayPal shows that this is a very real market, with an increasing number of options for target merchants,” he says.Related: For Some Businesses, Square Register Can Replace Traditional Point-of-Sales ToolsCynthia Wahl, for one, says she loves Square. The co-founder of Texas Toast Culinary Tours, a Fort Worth, Texas-based tour company, says she routinely uses her Square system to sign up last-minute attendees on their tours—an important financial catch-all for the two-year-old company.”It’s so simple to use,” Wahl says. “We signed up in about five minutes and were taking credit cards immediately. The money is in our account the next day. It just seems like Square is looking out for the small business owner.”But features vary from provider to provider. Texas Toast doesn’t run tours every month, so Wahl is loathe to pay a monthly fee, which is an option with one of the services. But Ablowtiz says it might make sense for those with a high volume of mobile transactions to opt for a monthly fee and a lower swipe rate. Your business may need to accept multiple forms of payment, generate invoices or process transactions internationally — features that vary from app to app.So, how do the main players stack up?

Facebook Is Rolling Out 360Degree Video to News Feeds With a Little

first_img For the first time, Facebook’s $2 billion acquisition of virtual reality leader Oculus VR, is starting to bear fruit.The social network has announced that 360-degree videos are now viewable on news feeds. While Facebook led development for 360-degree capability, the team collaborated with its Oculus division in order to create Facebook’s first consumer-facing VR product, the company’s chief product officer, Chris Cox, told The Verge.If you’ve never experienced 360-degree video before, prepare to be blown away. On desktops, the technology allows users to click and drag around a scene in order to see things from every angle. But on mobile (the update is only available for Android devices thus far), the experience is even more seamlessly immersive, as scenery changes in accordance with how users position their phones in space.Facebook is rolling out the technology with a handful of publishing partners including Saturday Night Live, Vice and Star Wars — which even released a brand new scene from the upcoming The Force Awakens film to mark the occasion. See for yourself right here: Related: With an Empathy Button, Facebook Will Be Even More Valuable to AdvertisersWhile anyone can upload 360-degree videos to Facebook, the cameras required to shoot this kind of footage will still set you back a pretty penny.“In the future, imagine watching 360 videos of a friend’s vacation to a small village in France or a festival in Brazil,” writes Facebook’s engineering director of video, Maher Saba, of potential future uses as the technology becomes more mainstream. “You’ll be able to look around and experience it as if you were there.”Facebook isn’t the first platform to foray into 360-degree video. After announcing 360-degree support last March, YouTube recently said it would be adding 3-D capability into the mix.Facebook CEO Mark Zuckerberg has long been vocal about his enthusiasm for VR, and has said that devices like Oculus could become the next major computing platform after smartphones.“In the future we’ll probably still carry phones in our pockets,” he said in a Q&A last June, “but I think we’ll also have glasses on our faces that can help us out throughout the day and give us the ability to share our experiences with those we love in completely immersive and new ways that aren’t possible today.”Related: Facebook Just Gave Small Businesses a Bunch of New Tools Enroll Now for Free September 24, 2015 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Nowcenter_img 3 min read This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.last_img read more

Justice Department Looking Into Data Breach at Uber Sources Say

first_img Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. December 18, 2015 Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals The U.S. Department of Justice is pursuing a criminal investigation of a May 2014 data breach at ride service Uber, including an examination of whether any employees at competitor Lyft were involved in the episode, sources familiar with the situation said.Earlier this year, Uber revealed that as many as 50,000 of its drivers’ names and their license numbers had been improperly downloaded. An investigation by Uber determined that an Internet address potentially associated with the breach can be traced to Lyft’s technology chief, Chris Lambert, Reuters reported in October.Department of Justice spokesman Abraham Simmons said on Wednesday he could not confirm or deny a criminal probe. No one has been accused of any wrongdoing, and it is unclear whether anyone will ultimately be charged in connection with the breach.A recently hired attorney for Lambert, former federal prosecutor Miles Ehrlich, said Lambert “had nothing to do” with the breach.”Given that Uber apparently lost driver data, a law enforcement investigation is to be expected,” Ehrlich said. “And the benefit is that the culprit here is going to be identified – and that’s going to remove Chris’ name from any conversation about Uber’s data breach, as it should.”In a statement on Friday, Lyft said “we have not been contacted by the DOJ, U.S. Attorney’s office or any other state or federal government agency regarding any investigation.”Uber declined to comment. The people familiar with the matter could not be named because they were not authorized to speak publicly.Search for hackerLyft is much smaller than Uber, which operates in more than 300 cities in 67 countries and has raised $7.4 billion from investors. The companies, based in San Francisco, compete fiercely for drivers and customers.Uber learned last year that someone downloaded its driver database, which should have been accessible only with a digital security key. A search for that key turned up a copy on the code-development site GitHub, where it had been left by mistake.Uber then obtained information from GitHub about who had connected to that page before the breach and found only one Internet Protocol address that did not belong to an Uber user or have another plausible explanation, according to court documents. Uber filed a civil lawsuit in San Francisco federal court in February in an attempt to unmask the perpetrator. The company’s court papers claim that an unidentified person using a Comcast IP address had access to the security key.On its own, Uber investigated that address and determined that it had been assigned to Lambert, Reuters reported in October.A U.S. judge ruled that Uber could further probe the IP address, saying it was “reasonably likely” that such an inquiry could help identify the hacker. That ruling is on hold pending an appeal.Sworn statementAttorneys for the unnamed Comcast subscriber have pointed out in court that the data breach was conducted from a different IP address than the Comcast address that accessed the security key. Lyft said that Uber allowed the key for the database “to be publicly accessible for months before and after the breach.”The IP address the hacker used is associated with Anonine, a virtual private network service based in Sweden that is known for vigorously protecting the privacy of its users, two people familiar with the situation told Reuters.Ehrlich said Lambert offered to provide Uber with a sworn statement that he had nothing to do with the breach, made under penalty of perjury.Lambert signed the statement over the summer, a separate source familiar with the situation said. In it, Lambert also said he was not aware of anyone who has copies of Uber’s database, and that he did not instruct anyone to access it, the source said.However, Lyft and Ehrlich declined to confirm or deny that Lambert’s Comcast address connected to the GitHub page containing the key. They also declined to give details about Lyft’s internal investigation of the matter.Lyft reiterated on Friday that it investigated the matter “long ago” and concluded “there is no evidence that any Lyft employee, including Chris, downloaded the Uber driver information or database, or had anything to do with Uber’s May 2014 data breach.”Uber’s lawsuit alleges the hacker violated civil provisions of the federal Computer Fraud and Abuse Act, as well as a similar California law. It is unclear if the leaked driver information was ever used by the hacker or anyone else.(Editing by Jonathan Weber and Matthew Lewis) 4 min read This story originally appeared on Reuters Register Now »last_img read more
