Nature Inspires Hi-Tech Design

first_imgScientists and engineers continue the gold rush to imitate nature’s solutions to problems.Enzymes: “Bio-inspired biomimetics can outperform natural coenzymes” (Science Daily). Chemists have imitated cellular catalysts and have exceeded the natural counterparts (at least for industrial redox applications).Barnacle bills: “Do we need to wipe out clingons?” (BBC News): Understanding how barnacles and mussels cling to ships and propellers might save a lot of money some day.  “I think these are incredible little micro-worlds,” Dr Raeanne Miller says, “with lots and lots of different types of creatures, each one doing their own thing to survive in some incredibly harsh environments.”Sandcastle worm secrets: “Sandcastle worms serve as inspiration for a new type of underwater adhesive” (Science Daily). This creature is another “cling-on warrior” that scientists at UCSB are analyzing for adhesive applications in medicine and other wet environments.Snake charm: “Snake gait: Science observes nature to invent new ways of moving” (Science Daily). “It has no wheels or legs or anything to help itself along, and yet it is able to move and to move quite fast. In terms of mobility, the snake is a masterpiece of engineering, and it is no coincidence that it should be studied to uncover the physics underlying its locomotion.”Salamander swimmer: “A new salamander robot has been designed that can walk, swim and turn around corners.” See the TED Talk video clip on Live Science showing the robot, and its inventor’s reasons for wanting to study animal motion, including salamanders and cats.Tree oil: “Is lignin the crude oil of the future? Maybe so, thanks to the sun and photocatalysts” (PhysOrg). Currently, lignin is a waste product of paper production, but it’s loaded with chemicals that could be useful in many applications.Electric eel watch: “Shocking! ‘Electric Eel’ Fibers Could Power Wearable Tech” (Live Science). “Stretchy fibers that mimic electric eels could be woven into clothing to power wearable technology one day, new research suggests.”Algae fashions: “Healthy and diseased marine algae inspire new designs” (BBC News). Microscope studies of algae have inspired a Scottish designer to make colorful scarves and pillows.Blind cave fish nursing: “Regulating IV infusion with innovative blind cave fish-inspired sensor” (Science Daily). How can a blind fish help humans?Inspired by the blind cave fish, researchers at the Singapore-MIT Alliance for Research and Technology (SMART) have developed Micro-Electro-Mechanical Systems (MEMS) flow sensor so tiny and sensitive that it can be implanted into the IV or intravenous set-up, to aid in regulating the velocity of the fluid flow with minimal intervention by the nurses, thereby reducing their workload while increasing their productivity by 30%; and significantly decreasing the complications of drug infusion via IV therapy. These sensors can also be incorporated into marine underwater robots, lending them sensitivities to wakes, akin to the blind cave fish itself, so that the robots can manoeuvre in a highly energy-efficient manner.Clam TV: “Color-Morphing Clams Could Inspire New Smartphone & TV Screens” (Live Science). With just ambient sunlight, giant clams produce an astonishing array of colors—including blues, greens, golds and, more rarely, white—by means of iridocytes. “Producing color the way giant clams do could lead to smartphone, tablet and TV screens that use less power and are easier on the eyes,” a biologist says.Beetle condenser: “Beetle-inspired discovery could reduce frost’s costly sting” (Science Daily). “In a discovery that may lead to ways to prevent frost on airplane parts, condenser coils, and even windshields, a team of researchers led by Virginia Tech has used chemical micropatterns to control the growth of frost caused by condensation…. The inspiration for the work came from an unlikely source — the Namib Desert Beetle, which makes headlines because it lives in one of the hottest places in the world, yet it still collects airborne water.”Bladderwort suction: “This plant sucks! (but how? )” (Science Daily): The lowly bladderwort has one of the fastest traps in nature. “If we can work out how the bladderwort can grab food so quickly, it could also have applications in other fields by helping us develop tools that can rapidly capture small samples of fluids. Finding out how a bladderwort sucks could possibly also lead to biomimetic technical innovations.”Plant printing: “Novel 4-D printing method blossoms from botanical inspiration” (Science Daily): Another project from Harvard’s Wyss Institute for Biologically Inspired Engineering—”Inspired by natural structures like plants, which respond and change their form over time according to environmental stimuli, the team has unveiled 4-D-printed hydrogel composite structures that change shape upon immersion in water.” One researcher commented, “It is wonderful to be able to design and realize, in an engineered structure, some of nature’s solutions.”Plant antenna: “New fluorescent nanomaterials whose inspiration was taken from plant antenna systems” (Science Daily): From the Basque country of Spain comes this project: “These new multifunctional materials aim to imitate the photosynthetic organisms of plants. These microorganisms consist of thousands of chlorophyll molecules embedded in a protein matrix, which provides them with a specific orientation/arrangement and intermolecular distance.”Bat avoidance: “How bats recognize their own ‘bat signals’ – Researcher discovers unique mechanism bats use to overcome communication interference in the wild” (Science Daily). “The mechanism that allows individual bats to avoid noise overlap by increasing the volume, duration and repetition rate of their signals has been uncovered by a new study” at Tel Aviv University. “Unlocking the mystery of bat echo recognition may offer a valuable insight into military and civilian radar systems, which are vulnerable to electronic interference.”Science is fun again, thanks to biomimetics. Inspiration from nature’s designs is leading to well-funded projects that promise useful and even lifesaving applications. Only a few researchers toss in extraneous evolution verbiage. The real focus is on intelligent design.Teachers and speakers: get inspired from our Biomimetics Category, where you will find dozens of news stories over the last decade showing the power of design to inspire scientists and engineers. Show kids the variety of animals and plants that are inspiring awe in biologists about how they solve problems. Give them a vision of the treasure chest out there in the world waiting to be explored. Let’s raise up an army of ID-friendly researchers who can improve the world and leave Darwin in the dust. (Visited 23 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgBarcelona captain Lionel Messi named FIFA’s The Bestby Carlos Volcanoa month agoSend to a friendShare the loveBarcelona captain Lionel Messi has been named FIFA’s The Best Player of the Year.He beat Juventus striker Cristiano Ronaldo and Liverpool’s Virgil van Dijk to the crown.Betting odds had Van Dijk as the favourite after winning the Champions League, but the Argentine rose above the Liverpool defender after finishing second in the first two years of the award, while he didn’t even reach a podium finish last year.”I want to thank everyone who decided to give me this recognition,” Messi said as he collected his trophy.”For me, individual awards are secondary and the collective comes first.”But today is a special day for me.”I have my wife and children here, and it’s the first time they’ve come.”Having them here to enjoy this is priceless.”They love football and they’re watching everyone around them shyly.”Messi dominated for Barcelona last season.Now, he’s favourite to go on and win the Ballon d’Or, as happened with Ronaldo twice and Luka Modric in 2018.

17 days agoBig Sam: Man Utd could be RELEGATED

first_imgBig Sam: Man Utd could be RELEGATEDby Paul Vegas17 days agoSend to a friendShare the loveFormer England boss Sam Allardyce says Manchester United could be RELEGATED this season.The former Bolton, Newcastle and England manager cited United’s side in 1974 that, against all expectations, went down to the second tier. With Solskjaer overseeing the club’s worst start in 30 years, Allardyce has used the side from 45 years ago as a warning to the current crop that they are not too good to be relegated. He told talkSPORT: “It isn’t beyond the realms of possibility that they could catastrophically fall into more problems if confidence goes and injuries stay like they are.”Players tend not to get as fit as quick as they would do when things are going well, that’s an absolute fact. There’s the disturbance of [Paul] Pogba wanting away and who will pop up next saying, ‘I see this going the wrong way, I want to leave?'”Manchester United do not have enough goals and you can see it becoming a struggle. Hopefully it’s not a struggle down the bottom end, but they’re certainly heading that way.” About the authorPaul VegasShare the loveHave your saylast_img read more

Cab company not liable for drivers alleged sex assault on passenger

first_imgTORONTO – A taxi company cannot be held liable for the alleged sexual assault of a passenger by one of its drivers, Ontario’s top court ruled on Friday.In dismissing an appeal by the complainant, the Court of Appeal sided with a lower court judge that the company had done no wrong.“The alleged sexual assault may be characterized as only coincidentally linked to the activities of the taxi company,” the Appeal Court said. “The taxi company did not require or permit the driver to touch the customer in any intimate body zones.”The alleged incident arose when a woman had a friend at a party call United Taxi in Kitchener, Ont., late one evening to come get her. The woman, who was intoxicated, claimed the driver sexually assaulted her. She sued him and the owner of the cab. She also sued the cab company on the basis that it was liable for the driver’s actions.In September last year, Superior Court Justice David Broad dismissed her claim against the company.Evidence was that the driver had no criminal record. Nor was there any indication the company knew, or should have known, that he might have had a propensity for, or history of, sexual or other violence. As a result, Broad said, it would defy common sense to hold the company responsible for the alleged assault.“The wrongful acts alleged by the plaintiff against (the driver) were only coincidentally linked to United Taxi’s activities as the operator of a taxi-dispatching business,” Broad ruled.The woman appealed. While she didn’t argue the company had actually done anything wrong, she nevertheless maintained it bore responsibility.The Appeal Court disagreed even though an employer can sometimes be held responsible for an employee’s misdeeds without having been negligent or having done something blameworthy.Such a situation is known as “vicarious liability,” and most commonly occurs when an employee accidentally causes loss or damage to a third party. An example might be when a supermarket worker leaves a mop on the floor and a customer trips on it.“The more difficult issue is when an employer should be found vicariously liable for an unauthorized, intentional wrong, such as a sexual assault, committed by the employee,” the Appeal Court said.In such cases, Associate Chief Justice Alexandra Hoy wrote in the decision, courts generally refrain from imposing liability for an employee’s “abhorrent, intentional acts.”A key consideration in making an exception, Hoy said in citing case law, is the existence of a strong connection between what an employer asks an employee to do and the wrongful act itself.“It must be possible to say that the employer significantly increased the risk of the harm by putting the employee in his or her position and requiring him to perform the assigned tasks,” the Appeal Court noted.In analyzing this case, Hoy agreed that a driver has some power over a lone, intoxicated woman, but said the connection to the company’s demands of its employees wasn’t strong enough to make it responsible.“Sadly, however, she is prey not only to taxi drivers,” the court said. “The power the driver allegedly wrongfully exercised was not predicated on his employment.”The court also noted the alleged assault did not further the company’s aims. In fact, its driver rules state: “Do not touch any customer if possible,” and “Do not ask a customer out for a date.”The Canadian Press does not name alleged victims of sexual assault without their active consent.last_img read more

No place like home Ohio State volleyball continuing to spike visiting competition

The mantra of “Home Sweet Home” has been the theme for several Ohio State athletic teams that have enjoyed the most success playing on university grounds.The Ohio State men’s volleyball team has been no different. It has made its home at St. John Arena a nightmare for opposing teams.Coach Pete Hanson said that the comfort level at home has really helped elevate his team’s play.“I think some teams have a harder time adjusting to the bigger arena and that helps our guys a lot,” Hanson said.The Buckeyes have been the definition of “perfect” at home, not only winning all five matches this season, but also sweeping all three sets in each of those respective matches. They have won each home set by an average margin of seven points.Hanson said that playing in St. John Arena every day for practice has been important for the players.“It is a great facility that, when set up for volleyball, has a very good feel to it for our guys. Being able to practice every day there makes a huge difference also,” Hanson said. “The great lighting and very good visual surroundings are what help to make St. John a great place to play.”Hanson said that while he is pleased with his team’s home success, he knows that tougher tasks still lie ahead.“We have some very good teams still scheduled to come to St. John Arena and I think our early schedule at home has been a bit easier than what we will finish with,” Hanson said.After facing Carthage this Friday, the Buckeyes don’t return home until early March when they face No. 7 Penn State in a rematch from an early-season meeting. They then go on the road again for a couple of weeks before finishing the regular season with three consecutive matches at home against Midwest Intercollegiate Volleyball Association conference opponents.Being able to replicate their early home domination during that final, three-match stretch will be essential for the Buckeyes to win the MIVA conference.“Home-court advantage for the MIVA playoffs is huge,” Hanson said. “We always want to win the conference and be the home team for all the rounds of the tournament.”Earning home court advantage in the playoffs would be instrumental for the Buckeyes considering how they have played at home already this season. The winner of the MIVA playoffs gains berth into the NCAA Men’s Volleyball Final Four.Hanson did not understate what that meant to his team. “That is truly one of our top priorities each and every year,” Hanson said. read more

Ohio State track and field teams get season underway with Buckeye Classic

Then-redshirt-sophomore Cory Kunze jumps over a hurdle during the Jesse Owens Track Classic April 14, 2012, at Jesse Owens Memorial Field.Credit: Shelby Lum / Photo editorThe Ohio State track and field teams got their seasons off to a fast start in their first meets of the year.The teams opened their indoor seasons at the Buckeye Classic in the French Field House Friday, playing host to Wright State, Marshall, Dayton, Kentucky State, Ohio and Ashland, in addition to unattached runners.The men’s team had an OSU runner place first in four of seven individual running events. There were three first place finishers in field events.Senior sprinter and hurdler Demoye Bogle won the 60-meter hurdles with a time of 7.65 seconds to break his own school record. This winning time was also a French Field House record and was one of the top finishing times in Division I hurdles this season. Redshirt-freshman Donovan Robertson came second behind Bogle with his personal best time of 7.74 seconds but with the second best in school history.Junior sprinter and hurdler Timothy Faust also had a personal best time of 6.77 seconds at the Buckeye Classic in the 60-meter run.The season opener generated about 1,000 fans.In five of seven individual races, the OSU women’s squad had runners finish first and second. Senior sprinter Chesna Sykes finished first in the 60-meter dash and the 200-meter dash.Along with many first place finishers, there were also three personal bests for women’s track recorded on the day. Sophomore sprinter and hurdler Alexis Franklin came in second in the 60-meter hurdles with a personal best 8.35 seconds.Junior sprinter and jumper Abie Ehimwenman received her personal best mark of 6.01 meters in the long jump, putting her in first place. Senior thrower Emily Taylor grabbed another personal best and third place with an 18.71 meter toss in the weight throw.OSU’s young runners showed off their talents in the 3,000-meter run, with sophomore distance runner Minori Minagwa claiming first with a time of 10 minutes 20 seconds and freshman distance runner Jill Kanney taking second, just two seconds behind Minagwa.Next weekend, the women’s team is set to hit the road to travel to Lexington, Ky., for the Kentucky Invite and the men’s team is set to be in State College, Pa., for the Penn State Invite. read more
