Japanese scientists explore electric roads for EVs Their solution is in the form of a wireless power prototype that can successfully transmit electricity through the concrete block. They consider the prototype as an early step to improve on, and that such an approach can be used one day to keep electric vehicles on the move. Takashi Ohira, an electrical engineering professor at the Toyohashi University of Technology, who leads the team, has developed his electric field coupling system to supply a charge to a car through its tires. The goal is to enable power transmission as the vehicle’s tires travel along the road with suitable efficiency and power transfers.In the demo, a metal plate was placed along with a four-inch layer of concrete, representing the road surface. Electricity between 50 and 60 watts was transmitted to actual-size automobile tires. The demo also showed a light bulb, attached between the two demo car tires, turning on.The university team’s project is called EVER (Electric Vehicle on Electrified Roadway). The focus is research aimed at using wireless power transmission technologies based on electric field coupling for transmitting power to a running vehicle.The July demo is the latest of similar past efforts by the researchers. Last year, Toyota Central R&D Labs and Ohira reported on their work to allow electric cars to drive unlimited distances on an electrified roadway. They reported a system that similarly transmits electric power through steel belts inside the two tires and a metal plate in the road. They presented their work at a workshop in Kyoto. To test how much energy would be lost as electricity traveled through the tire rubber, the researchers also set up a lab experiment with metal plates. “Less than 20 percent of the transmitted power is dissipated in the circuit,” said Ohira at that time. With enough power the system could run typical passenger cars, he added.To make their present technology useful, the electric power needs to be increased by 100 times. But, moving ahead, the group said that they are up to the task of meeting the project’s challenges. Explore further (Phys.org) — Electric vehicles’ future continues to tease scientists to devise promising and practical ideas to keep these cars moving along the highways without having to pull over and wait for a battery recharge. Solutions for the so called “charging and range problem” took yet another twist this month when a Japanese university team demonstrated how electricity can be transmitted to a pair of tires through a four-inch-thick block of concrete, the type of concrete used on roads. The team took its demo to WTP (Wireless Technology Park) 2012, a trade show on wireless technologies, earlier this month in Yokohama. vit Techon Citation: Japan demo shows electricity entering EV through tires (2012, July 8) retrieved 18 August 2019 from https://phys.org/news/2012-07-japan-demo-electricity-ev.html More information: © 2012 Phys.org This document is subject to copyright.

More information: Eye patches: Protein assembly of index-gradient squid lenses, Science (2017). science.sciencemag.org/cgi/doi … 1126/science.aal2674AbstractA parabolic relationship between lens radius and refractive index allows spherical lenses to avoid spherical aberration. We show that in squid, patchy colloidal physics resulted from an evolutionary radiation of globular S-crystallin proteins. Small-angle x-ray scattering experiments on lens tissue show colloidal gels of S-crystallins at all radial positions. Sparse lens materials form via low-valence linkages between disordered loops protruding from the protein surface. The loops are polydisperse and bind via a set of hydrogen bonds between disordered side chains. Peripheral lens regions with low particle valence form stable, volume-spanning gels at low density, whereas central regions with higher average valence gel at higher densities. The proteins demonstrate an evolved set of linkers for self-assembly of nanoparticles into volumetric materials. Explore further Optic lobe of giant squid found proportionally smaller than for other cephalopods (Phys.org)—A team of researchers with the University of Pennsylvania has uncovered the means by which squid eyes are able to adjust to underwater light distortion. In their paper published in the journal Science, the group describes their work analyzing squid eye parts under a microscope, what they found and then offer an explanation of the process involved in squid vision. Tobias Madl with Medical University of Graz in Austria offers an overview of how lenses work in general in a Perspective piece in the same journal issue, and outlines the work done in this new effort. Credit: CC0 Public Domain Prior work with squid had shown that their eyes are unique. The refractive index of each lens is greatest at its center and grows smaller toward the edges. This contrasts sharply with how glass lenses work—they have the same refractive index over their whole area—their shape focuses the light. The unique squid lens has clearly evolved to better handle the murky light available in the ocean, allowing the creatures to see much better than humans and many other sea creatures that have traditional lenses. In this new effort, the researchers sought to learn how the squid eye is able to pull off this feat.The study consisted of cutting squid eyes and studying them layer by layer under a microscope and applying small-angle X-ray scattering to learn more about the way light behaved as it encountered each layer and part of a lens. The researchers found that the lens was made mostly of a protein gel in the S-crystalline family. They attribute changes in the refractive index to the arrangement of the crystalline molecules. They found that in the center of the lens, the molecules were bound together in relatively large structures. The structures grew smaller relative to their distance from the center. At the edges of the lens, the structures were made from just two molecules. This works for the squid, because the structures allow for bending light differently depending on which part of the lens is struck. The result is far more clarity under dim light conditions.

Citation: Scientists reach milestone in 3-D laser writing in bulk silicon (2017, October 18) retrieved 18 August 2019 from https://phys.org/news/2017-10-scientists-milestone-d-laser-bulk.html Researchers fabricate 3-D silicon structures with a focused infrared laser More information: Margaux Chanal et al. “Crossing the threshold of ultrafast laser writing in bulk silicon.” Nature Communications. DOI: 10.1038/s41467-017-00907-8 Journal information: Nature Communications The researchers expect that the results will open the doors to 3D laser writing for silicon photonics applications, as well as for studying new physics in semiconductors.The scientists, Margaux Chanal et al., from institutes in France, Qatar, Russia, and Greece, have published their paper “Crossing the threshold of ultrafast laser writing in bulk silicon” in a recent issue of Nature Communications.In previous attempts at ultrafast laser writing in bulk silicon, scientists found that femtosecond lasers simply weren’t capable of structurally manipulating the bulk silicon, even when the laser energy was increased to the highest pulse intensity technologically possible. In the new study, the researchers found that, fortunately, there is no physical limit that prevents ultrafast laser-induced structural manipulations of bulk silicon. Instead, they found that the laser energy has to be delivered in the medium in an abrupt way in order to minimize losses from nonlinear absorption. This finding revealed that the problem of all past efforts arose from the laser’s small numerical aperture (NA), which refers to the range of angles over which focused laser light can be delivered. The researchers calculated that, in order to achieve the desired results, it would be necessary to obtain extreme NA values that have so far not been realized in this area.In order to reach these extreme NA values, the researchers borrowed a technique from advanced microscopy called solid-immersion microscopy. The idea is similar to the commonly used liquid-immersion microscopy, in which a small drop of oil is placed on the slide. As oil has a larger refractive index than air, the oil reduces the amount of optical refraction (bending of light) as the light travels between the slide and the microscope lens. This, in turn, increases the NA and the associated microscope’s resolution (the NA for a microscope measures the range of angles over which light is collected rather than delivered). The difference with solid-immersion microscopy is that a solid material with a high refractive index is used instead of a liquid. (Phys.org)—It has taken more than 20 years, but researchers have demonstrated for the first time that femtosecond lasers can be used to structurally manipulate bulk silicon for high-precision applications. Since the late ’90s, researchers have been using the ultrashort pulses of femtosecond lasers to write into bulk materials with wide band gaps, which are typically insulators. But until now, precise ultrafast laser writing has not been possible for materials with narrow band gaps, such as silicon and other semiconductors. © 2017 Phys.org This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. In the new study, the researchers used silicon spheres as the solid-immersion medium. They found that, when focusing the laser at the center of a sphere, they could completely suppress refraction and greatly increase the NA. The extreme NA values allowed the laser pulses to achieve sufficient ionization to break chemical bonds in the silicon, which in turn causes permanent structural changes in the material.”The in-depth understanding of the physics of the interaction and propagation of ultrashort laser pulses in low-band-gap semiconductors, like silicon, enabled us to solve this long-standing problem and achieve controlled material structural modifications, appropriate for applications,” coauthor Stelios Tzortzakis, at the Texas A&M University at Qatar, FORTH, and the University of Crete in Greece, told Phys.org. “Even more, the localized energy deposition in the medium results in out-of-equilibrium phases with extreme thermal and pressure gradients that can enable the creation and study of new states of matter, previously unreachable in laboratory environments.” In the future, the researchers plan to further push the boundaries of this approach by borrowing another microscopy technique called 4-Pi arrangement. This concept involves crossing multiple laser pulses with extreme NA values at the centers of spheres, which may lead to even greater possibilities in ultrafast laser writing in bulk silicon and other semiconductors.”3D laser writing applicable to silicon may drastically change how things are designed and fabricated in the important field of silicon photonics,” said coauthor David Grojo at CNRS/Aix-Marseille University in France. “Silicon photonics is seen as the next revolution of microelectronics using light at the chips level for ultimate speed data processing. However, it remains today a 2D world because of the planar lithographic methods used for fabrication (SOI technology). With our method we can envision the equivalent of a 3D printer for rapid prototyping of any innovative architecture. This will make possible for silicon photonics specialists to design things in 3D that must represent a real booster for the emergence of disruptive technologies and new concepts.” Experimental setup of using 60-femtosecond laser pulses for laser writing in silicon.

by NPR News Jeff Brady 8.28.19 10:39am After a two-week journey sailing across the Atlantic Ocean, 16-year-old Swedish climate activist Greta Thunberg has arrived in New York. She tweeted Wednesday morning that she had anchored off Coney Island. After clearing customs and immigration, she is expected to come ashore in Manhattan in the afternoon.Thunberg is in the U.S. for the United Nations Climate Action Summit and says she sailed to avoid the greenhouse gas emissions that come with flying on a commercial jet.Thunberg documented her journey on social media, including posts in rough seas with waves crashing over her. Thunberg says she first learned about climate change when she was 8 years old and became very concerned about the future of humanity. At age 11, she says she was depressed and stopped talking and eating.”Later on I was diagnosed with Asperger’s syndrome, OCD and selective mutism,” she told a crowd gathered for a 2018 TED Talk in Stockholm. “That basically means I only speak when I think it’s necessary. Now is one of those moments.” On Aug. 20, 2018, Thunberg began skipping school and protesting by herself outside Sweden’s Parliament. She called it a school strike and demanded that adults do more about climate change.”I handed out fliers with a long list of facts about the climate crisis and explanations on why I was striking,” she said in a Facebook post. She talked about her strike on Twitter and Instagram, and protests quickly spread.Now, just one year later, students hold hundreds of school strikes every Friday around the world. Thunberg also has been nominated for a Nobel Peace Prize, addressed the United Nations climate conference in Poland and met Pope Francis. The teenager has a knack for making the complicated issue of climate change sound simple. For that she credits being on the autism spectrum, calling it a gift because it helps her see issues more starkly. “If burning fossil fuels was so bad that it threatened our very existence, how could we just continue like before? Why were there no restrictions? Why wasn’t it made illegal?” she asked in her TED Talk. Thunberg’s activism has attracted critics. Conservative French lawmakers boycotted a speech by Thunberg earlier this summer and mocked her as a “prophetess in shorts.”One critic even referred to Thunberg’s diagnoses. Australian conservative columnist Andrew Bolt, in a Herald Sun blog post, wrote, “No teenager is more freakishly influential than Greta Thunberg, the deeply disturbed messiah of the global warming movement.”Thunberg shot back on Twitter, “I am indeed ‘deeply disturbed’ about the fact that these hate and conspiracy campaigns are allowed to go on and on and on just because we children communicate and act on the science.” Still, many teenagers around the globe are attracted to Thunberg’s message, and they are showing up in the streets. Last March, students around the world staged a climate strike modeled on Thunberg’s school strike. Just about every U.S. state had an event, even in politically conservative areas. Freddy Finney-Jordet, 17, organized a protest on a street corner in downtown Bend, Ore. He says he was inspired by Thunberg’s determination. “She kind of looks in the camera and has this look of, ‘I’m doing this. Nobody can stop me,’ ” Finney-Jordet says.Before last spring, gun control and LGBTQ issues were his priorities. “After that protest, which at first I thought was going to be kind of a one-off thing for me, I started taking a look at exactly how severe the climate crisis was, and that’s been my focus ever since,” he says.Thunberg’s fans will be watching as she joins protests connected to the U.N. Climate Action Summit, and then addresses the summit.She also plans to visit Canada and Mexico before traveling to Chile for a climate conference in December. Thunberg’s family says she’s taking a sabbatical from school this year to focus on her climate activism.Copyright 2019 NPR. To see more, visit NPR.

Nagpur-based sculptor and performance artist Surbhi Bhattad began her month-long performance art here Saturday to protest gender abuse and rape.She is performing at Dilli Haat in south Delhi and at Great India Place Mall at Noida with an act ‘Does the Glorious Movie Scenes Inspire You To Rape?’The performance is a body act featuring the young artist, who lies on the floor like a corpse at a crowded public venue. She is clad in white with a leather chastity belt strapped to her groin. The chastity belt — shaped like a woman’s pelvis — has a screening device around the pubic region that beams footage of popular ‘rape sequences’ from eight Bollywood blockbusters with the message, ‘Does this inspire you to rape?’ Also Read – ‘Playing Jojo was emotionally exhausting’Bhattad will perform at the two venues for three hours everyday to challenge onlookers to react to the footage. ‘The performance is difficult and disturbing because the footage sends different vibrations in my body. It makes me cry. It involves a certain amount of risk,’ said Bhattad after a performance. The reactions of the audience, who had to look at her pelvis to see the videos, ranged from outrage to trauma. Most of the male viewers admitted to feeling ‘confused’ and ‘humbled’. The performance has been inspired by the artist’s intervention work with ‘victims of gender and child abuse’ in Nagpur. Also Read – Leslie doing new comedy special with Netflix‘I have been speaking to women who have been sexually and psychologically abused. Bollywood movies have been a trigger in titillating libidos and reckless behaviour among the lower middle social segments, where education and awareness are yet to make incursions,’ Bhattad said.The artist said ‘she found it easy to engage with her body in carrying forth the gender message’. Bhattad’s performance has been described by critics as an eye-catching exhibit among 15 works of multi-media public art across 15 venues in the capital in a new project ‘Publica’, which opened Saturday for a month. Designed around the theme, ‘Spectacle’, the exhibits highlight ‘pollution, road accidents, body building, changing play spaces in cities and yoga’ by three international and 12 Indian artists.The venues include Indira Gandhi International Airport, DLF Emporio, Promenade Mall, India Habitat Centre, Dilli Haat, Select City Walk, The Great India Place, Garden of Five Senses and Sabyasachi @ Carma fashion store in Mehrauli. The festival is being supported by the Delhi government and Ho Ho buses which will touch the venues in a special festival run everyday. Publica has been curated by the Floodlight Foundation led by Delhi-based arts entrepreneur Surbhi Modi. ‘The festival is trying to embed appreciation and understanding of public art into everyday life and use arts as a tool to build awareness,’ Modi said.

Do not comb wet hair: It is best not to comb wet hair as this leads to greater chances of hair breakage and fall. Let it be dry or semi-dry before combing.
Bengal Chief Minister Mamata Banerjee with members of the Bhutan Royal Family. The Bhutan Prime Minister, in a break from protocol, drove Banerjee to her hotel on Wednesday. Banerjee had on Wednesday discussed various issues of mutual interest with Bhutan’s Foreign Affairs Minister during her trip to the Himalayan nation. “Bengal is the only eastern state sharing a contiguous border with Bhutan. We had a very useful discussion on various important issues common to Bhutan and Bengal. We reiterated our commitment towards continuance of our excellent relationship with Bhutan in line with our long, long tradition,” Banerjee said in a Facebook post. The Chief Minister was invited for a luncheon audience with His Majesty the Fourth Druk Gyaplo and their Majesties the Queen Mothers at Dechenchholing Palace.
Kolkata: Bengal has witnessed massive infrastructure development in the past seven years, to ensure a better firefighting mechanism in the state.Chief Minister Mamata Banerjee said: “Since pre-Independence to 2011, as many as 100 fire stations had come up in the state. While in the past seven years, 41 fire stations have come up in Bengal and 20 are under construction. Moreover, the process of setting up another 41 is also going on.” She said that it is a remarkable development of infrastructure facilities. Also Read – Rain batters Kolkata, cripples normal lifeBanerjee on Tuesday flagged off 30 fire tenders of 5,000 litre capacity and 20 fire tenders of 8,000 litre capacity. The programme for the same was held outside Nabanna. She said as many as 674 fire fighting vehicles have been introduced in the past seven years and there are 136 motorcycle-mounted firefighting arrangements. “I feel there is a need to increase such arrangements to fight fire properly in congested areas,” the Chief Minister said, adding that some Panchayat areas are also getting congested and such mechanism is also needed in such places. These are also helpful in urban and semi-urban areas. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedShe further said that she had got the idea of introducing motorcycle-mounted firefighting arrangements during her visit to Germany. “Vehicles there ply at speeds of around 250 km per hour and I found that a road accident had taken place. Helicopters were pressed in to rescue the people. At the same time, I found that materials required for rescue operations were brought on motorbikes. After returning, I put forth the idea of introducing the motorcycle-mounted firefighting arrangement,” Banerjee said, adding that the Disaster Management department, the state Fire and Emergency Services department and police should take steps to introduce more motorcycle-mounted firefighting arrangements. She further added that pilot cars are now being engaged for piloting another vehicle and the use of motorbikes for the same purpose would be more economical. She further said that three hydraulic ladders were also introduced in the past seven years, to fight fires in high-rise buildings. Banerjee also directed the police to ensure coverage of maximum areas using CCTV cameras. She said: “It is not always possible to be present physically to maintain a vigil. So, installation of CCTV cameras will help to carry out better surveillance.” In the past seven years, fire stations have been constructed in different rural parts and infrastructure of the fire stations, which have been existing for the past several years, has also been improved.
Kolkata: Five persons were arrested for killing a two-month-old girl child at Ghughupara in Liluah, Howrah. It is alleged that they had also killed two more female infants a few months ago and buried their body somewhere neartheir houses. According to locals, Sanjay Gupta and Sangeeta Gupta of Ghughupara had two female infants who died mysteriously a few months ago. When neighbours asked about the cause of death, they allegedly told them the babies were suffering from some sort of septicemia and died due to that.

Due to suspicion, they enquired about the baby. But Sanjay and Sangeeta could not provide them with satisfactory answers. Smelling a rat, the neighbours detained them and asked several other questions. During questioning, Sanjay and Sangeeta said the child died due to some disease and they went to bury her in Ambagan area.

Meanwhile, Liluah police station was informed. The accused, Sanjay and Sangeeta, were manhandled by the neighbours before police reached the spot. Later, the police recovered them and started interrogating them in their house. Sources informed that during police interrogation, they could not provide satisfactory answers. Immediately, five including Sanjay and Sangeeta were detained. Without losing time, the police in presence of a magistrate dug the ground where the child’s body was buried. Later, Sanjay and Sangeeta admitted to have killed the child at the police station. They were arrested and will be produced before the Howrah Court on Monday. Locals alleged that they had killed all their children within a few months of their birth as they were girls. A neighbour of Gupta family said this time the Gupta family had buried the child alive and demanded stringent action against them.
Researchers have found that practicing what is known as a “dual n-back” exercise can lead to improvement in working memory, which is what people rely on to temporarily hold details in their mind like phone numbers and directions. The “dual n-back” is a memory sequence test in which people must remember a constantly updating sequence of visual and auditory stimuli. The study published in the Journal of Cognitive Enhancement suggests it is possible to train the brain like other body parts – with targeted workouts. Also Read – Add new books to your shelf”People say cognitive training either works or doesn’t work. We showed that it matters what kind of training you’re doing,” said lead author Kara Blacker who was with Johns Hopkins University in Baltimore at the time of the research.”This one task seems to show the most consistent results and the most impact on performance and should be the one we focus on if we’re interested in improving cognition through training,” said Blacker, now a researcher at the Henry M. Jackson Foundation for Advancement of Military Medicine Inc in Maryland. Also Read – Over 2 hours screen time daily will make your kids impulsiveThe researchers decided to compare directly the leading types of exercises and measure people’s brain activity before and after training.First, the team assembled three groups of participants, all young adults. Everyone took an initial battery of cognitive tests to determine baseline working memory, attention and intelligence. Everyone also got an electroencephalogram (EEG) to measure brain activity. Then, everyone was sent home to practice a computer task for a month. One group used one leading brain exercise while the second group used the other. The third group practiced on a control task.The training programmes compared are not the commercial products available to consumers, but tools scientists rely on to test the brain’s working memory.Everyone trained five days a week for 30 minutes, then returned to the lab for another round of tests to see if anything about their brain or cognitive abilities had changed.The researchers found that the group that practiced the “dual n-back” exercise showed a 30 per cent improvement in their working memory. That was nearly double the gains made by the group working with the other common task, known as “complex span”. The dual n-back group saw squares flashing on a grid while hearing letters. They had to remember if the square they just saw and the letter they heard were both the same as one round back. As the test got harder, they had to recall squares and letters two, three and four rounds back. The other test, called “complex span,” also involves remembering items in a sequence, but they do not need to continually update the items in their mind.”The findings suggest that this particular task is changing something about the brain,” said study co-author Susan Courtney, Professor at Johns Hopkins University.
Darjeeling: A leopard that had been tormenting the villagers at Lower Kaijaley in the Darjeeling Hills was finally trapped on Thursday.Villagers of Kaijaley, 2 km from Bijanbari, are spending sleepless nights with leopards taking away their dogs, goats and pigs. “It has been more than one and a half months that two adult leopards have been sighted in the Lower Kaijaley area. There is a small forest near the Reling Khola (river) which the leopards inhabit. They come to the village in search of easy prey,” stated KB Wattar, a resident.

The Forest department had set up a leopard trap in which the leopard was trapped. It had killed the goat that had been used as bait. “We had received information from the villagers and accordingly the range office had set up a leopard cage on Wednesday. On Thursday morning a female adult leopard was found trapped in the cage. We will take the trapped leopard to Bengal Safari in Siliguri,” stated Vikas V, Divisional Forest Officer (DFO.) The villagers have requested for more traps to trap the other leopard also. Bijanbari is located at a distance of 30 km from Darjeeling town.
Walter ‘Fred’ Morrison was not the kind of man to wait around for something to happen. A carpenter by trade and a natural salesman, he always had an eye for new inventions and it was selling a pie tin to a stranger that would be the inspiration for what would become a worldwide phenomenon. Back in 1871, William Russell Frisbie was making delicious fresh pies out of his home kitchen in Bridgeport, Connecticut. As the Frisbie Pie website tells us, by 1915 the family had moved their business to a three-story Bridgeport bakery and the Frisbie Pie Company was born.By 1920, Frisbie Pies were a resounding success, making over 50,000 pies a day, but it was the pie tins themselves that would lead to a new kind of revolution.Frisbie’s Pies 1920s delivery truck.Another big player in Connecticut is the Ivy League College Yale, and the Frisbie Pie Company listed Yale as one of its customers. The official Yale College website stakes a big claim in the invention of the Frisbee, alleging that as far back as 1920, students would throw around Frisbie pie tins during their study breaks.Frisbie pie tin. Photo by Doug Coldwell CC BY-SA 3.0Other legends have it that the whole town of Bridgeport was in on the game and once they had eaten their pie they would throw the pie tins from roofs and shouting “Frisbie!” to warn any unwitting passer-by to watch their heads, much like the golfing shout of “Fore!”.A frisbee made by Wham-O.Fast forward to 1957 and the Wham-O Toy Company (famous as the creators of that other circular plastic toy, the hula-hoop) has just bought the rights to a toy called the Pluto Platter.A dog jumping to catch a frisbee.As reported by the New York Times, Fred Morrison had been developing the concept since 1941, firstly naming it the “Whirl-o-Way” and then the “Flyin’ Saucer” but it wasn’t until it’s third incantation as the Pluto Platter with its aerodynamic shape and intergalactic raised print that the idea started to catch on. Morrison, ever the businessman, sold the idea to Wham-O for lifetime royalty rights.A frisbee containing some of the ashes of Ed Headrick. On display at Ripley’s Believe it or Not, London.

It was the right time and Fred Morrison was the right man to bring the Frisbee into the public imagination.Read another story from us: The Remarkable Turnspit Dog, a Breed Specially Designed to Help in the KitchenAs quoted in Time Magazine, Dr. Stancil Johnson, who serves as Frisbee’s official historian when not practicing psychiatry, states the reason that Frisbee has remained one of the most popular toys through the generations is that they are “the perfect marriage between man’s greatest tool—his hand—and his greatest dream —to fly.”

From brochures to invoices, color adds interest and gives you a professional edge. There are many routes you can take to add color to your printing options: inkjet, color laser, solid ink, personal printer or workgroup printer. For the most flexibility within your company, a networkable color printer is the ticket, and that usually translates to a color laser. We’re going to browse through a variety of colorful options, including a couple of multifunctions as well as a solid-ink offering from Xerox.The cost of running a printer is something to consider. The $1,759 (all prices street) Kyocera Mita FS-C5020N, for example, may not be an absolute speed demon, but it features a superefficient toner system that keeps your cost per page down. A toner-save feature like the Brother HL-2700CN offers is a smart way to extend the life of your consumables. The Lexmark C760n lets you designate which users are allowed to print in color–an easy way to conserve your color toner.Memory is important for users who throw large files at their color printers. A good chunk of built-in memory will keep the printer from getting brain freeze when you toss a graphics-heavy brochure at it. Most printers over $1,000, like the Lexmark C760n, come with 128MB RAM that can be upgraded if necessary. The C760n, for instance, maxes out at 512MB.At the lower end of the cost spectrum is the Brother HL-2700CN. It skims in at $500 with print speeds of up to 8 pages per minute in color and 31 ppm in monochrome. That’s pretty affordable for a network-ready color laser printer. For about $400, the Samsung CLP-510N gives you slightly slower speeds of up to 6 ppm in color and 25 ppm in monochrome; its built-in automatic duplexing is a nice extra.Printer speed involves more than just pages per minute–there’s also the time it takes to get the first page out. That’s where the $899 Xerox Phaser 8500/N flexes its solid-ink muscle. It can get the first color page out in less than 6 seconds, compared to 19 seconds for the Brother HL-2700CN. Solid ink technology also tends to produce very vivid colors and fast speeds overall.When your needs go beyond printing, a multifunction could be right up your alley. The $800 Epson AcuLaser CX11NF covers faxing, scanning and copying as well as printing. One trade-off for all that functionality is speed. Color speeds top out at 5 ppm. Compare to the $999 Hewlett-Packard LaserJet 2840, which comes in at 4 ppm in color and also comes stocked with direct digital photo printing. The Canon ImageClass MF8170c multifunction features high-quality flatbed scanning for $899.Lasers still can’t quite beat specialty inkjets when it comes to photo printing, but their speed and the cost of consumables make them a good choice for companies that focus on brochures and business documents. Throw in networking capability, and you get a versatile solution that will handle the needs of your small office or workgroup–and make your business more colorful.

1 min read If Windows 8 felt like a radical departure from previous iterations of Microsoft’s long-loved operating system, the tech giant is looking to inject a bit of fun familiarity back into Windows 10, which is slated for a summer release.Solitaire, which was removed from Windows 8 alongside other classics including Hearts and Minesweeper, will be baked back into Windows 10, Mashable reports. While Solitaire will receive a spot on Windows 10’s new start menu — another feature Microsoft had removed from Windows 8 much to loyalists’ disdain — the other games must be downloaded as add-ons from the Windows Store.The addition was discovered when Microsoft rolled out a preview of the new software earlier this week. A note explains that the return of Solitaire commemorates the 25th anniversary of the game on Windows.Related: Pac-Man and Google Maps: A Genius Match April 24, 2015 Growing a business sometimes requires thinking outside the box.
