Here’s the latest collection of bio-inspired designs brought to you by plants, animals, and cells.Speedy snail insulin (PhysOrg): We think of snails as among the slowest of animals, but this article says of “Snail’s speedy insulin: Bio-inspired insulin may act three times faster than current products.” The venom of cone snails has inspired a new insulin injection that works in 5 minutes instead of the usual 15. “To have something that has already been evolved—that’s a huge advantage,” the researcher stated.Gecko tires (Science Daily): Want to see “nature’s designs at work on the highways”? Imagine applying the principles of gecko toe adhesion where the rubber meets the road. NSF-funded researchers at Lehigh University, working with Michelin Tires, think their bio-inspired tire design will reach the sweet spot between traction, tire life and fuel efficiency. “Improving one quality almost always degrades another” in previous designs, but toes of geckos, grasshoppers and frogs are giving them ideas to achieve more of all three. “The results are promising.”Drug fishing (PhysOrg): Or is this “fish drugging”? This article says that “Tiny robot ‘nano-fish’ may one day deliver drugs inside the body.” Researchers in China and California are designing “innovative robotic devices, inspired by physicomechanical designs evolved in fish” but this time at the nano/micro scale. See also New Scientist‘s report on this bio-inspired technology that promises “drug guided missiles.”Seagull drones (The Conversation): Don’t get mad at the seagulls that try to swipe your sandwich. They’re helping engineers design flight paths to navigate city centers, this article says. Watch the video clip of their flight paths at the ocean, where they use updrafts efficiently to fly without flapping.So next time you are feeling ill-disposed towards gulls soaring in city spaces, possibly shielding your ice-creams as you stroll along the seafront, stop a moment to appreciate the complex decisions that these feathered pilots are making, second by second, as they respond to their continually changing aerial environment, in ways that engineers can, for now, only dream of.Squid trousers (Live Science): Those darn holes in the jeans; they’re not always fashionable. How would you like self-healing trousers? Squid are inspiring self-repairing clothing coatings, this article says, at the US Naval Research Laboratory. Some day, “clothes could fix their own rips with the help of coatings made of squid proteins, according to a new study.” Proteins in the teeth on the suction cups of squid are the key. Add this kind of material to the washer and dryer, and tears could heal themselves.Volvox chemotherapy (Science Daily): Claiming that this simple multicellular organism “evolved from self-assembly of individual cells,” this article nonetheless takes inspiration from that principle to design a new way of treating cancer. “Drawing from the lessons of evolution, they designed anti-cancer molecules that can self-assemble with each other into a complex structure through weak supramolecular interactions.” Go figure; if it works, cancer patients will no doubt credit the design, not the evolutionary tale.Cilia sensor (Nature Scientific Reports): Inspired by the coordinated motions of hair-cell bundles in the ear, engineers from three continents “report the development of a new class of miniature all-polymer flow sensors that closely mimic the intricate morphology of the mechanosensory ciliary bundles in biological hair cells.” The prototype shows high sensing performance. What can they do with it? “These self-powered, sensitive, flexible, biocompatibale [sic] and miniaturized sensors can find extensive applications in navigation and maneuvering of underwater robots, artificial hearing systems, biomedical and microfluidic devices.”Dragon bicycles (Science Daily): Athletes are always looking for lightweight yet strong materials. The dragon tree has vascular bundles with both properties, as well as the ability to resist tension and cushion compressive stress. Engineers in Germany think that inspiration from that design will have multiple innovations in everything from bicycle frames to architectural support structures to automobile bodies.Cricket hearing aids (The Conversation): Why does Rob Malkin at the University of Bristol show a video of crickets chirping in his article? He wants to show how their vibrating wings introduce a principle for use in “the future of hearing aids.” For such small creatures, they put out a lot of sound. He gives the credit to Darwin:The human ear is a miracle of mechanical evolution. It allows us to hear an astonishing range of sounds and to communicate and navigate in the world. It’s also easy to damage and difficult to repair. Hearing aids are still large, uncomfortable and as yet unable to deliver the rich and wonderful sounds we take for granted. Yet there may be a new way for us to replace damaged hearing from an unlikely source – the insect world.What’s new in artificial photosynthesis? Mimicking the way plants capture sunlight is a long-standing dream for engineers. This “pivotal biological reaction on the planet,” Science Daily says, consists of two reactions: splitting water and “fixing” carbon dioxide into simple sugars. Scientists at the University of Southampton “have reengineered the fundamental process of photosynthesis to power useful chemical reactions that could be used to produce biofuels, pharmaceuticals and fine chemicals.” But they’re only part way there; they speak of applications in future tense.Meanwhile, German scientists have made progress in splitting water with light. PhysOrg shows how they have designed the “first practical design for photoelectrochemical water splitting” using a self-contained solar cell. Details are published in the open-access journal Nature Communications. Their concept, they believe, could be upscaled to large applications, and “may be an important contribution towards the large-scale application of artificial photosynthesis.”Lignin liberators (PhysOrg): Lignin, the molecule that makes plant cell walls stiff, is a high-energy molecule that could produce efficient biofuel—that is, if scientists could figure out how to crack it open. Researchers at Sandia Labs tried a new approach; “For inspiration on how to break down lignin, the researchers looked to nature.” They found a bacterium that knows the secret. “Now that we know how to begin deriving value from lignin, a vast resource opens up,” they say.Final story: An inspiring mix of human and machine comes to life in PhysOrg‘s article on the Paralympics. Watch how engineers have been designing better wheelchairs, bicycles and prosthetic limbs so that great athletes with disabilities can celebrate their abilities.In the end, though, desire and muscle power, not fancy equipment, makes champions, she said.“You still have to have an engine,” she [Jamie Whitmore, bicyclist paralyzed from cancer] said with a smile. “You can’t sit on a couch and expect to win.”The athletes say that the prostheses, which are only poor substitutes for the real biological human parts, only provide gains of fractions of a second. The human element is the real inspiration, for both athletes and sports fans. All the more so when the athletes have had to overcome huge challenges, both mental and physical, not faced by the regular Olympic participants.Biomimetics serves up delicious soup of innovative designs inspired by life. The only thing Darwin supplies is the fly. Waiter! (Visited 25 times, 1 visits today)FacebookTwitterPinterestSave分享0
27 May 2013It was a day filled more with song and dance than with speeches as Africans gathered in Addis Ababa, Ethiopia on Saturday to celebrate the 50th anniversary of the African Union (AU) and its forerunner, the Organisation of African Unity (OAU).The many milestones in the continental body’s history were celebrated across Africa, but Ethiopia was a fitting stage for the main golden jubilee. It was here that the OAU was born in 1963, giving hope to many African countries which at the time were still battling against colonialism and apartheid.Interspersed with short messages of support from leaders including former Zambian President Kenneth Kaunda, AU Commission Chairperson Nkosazana Dlamini Zuma and Ethiopian Prime Minister Hailemariam Desalegn, the audience was treated to a programme of African traditional performances and cultural items.The spectacular show was put together by South African choreographer Somizi Mhlongo.A 10-minute video paid tribute to the late Ethiopian Prime Minister Meles Zenawi, who died last year. Zenawi has been widely praised as the person who led Ethiopia’s transformation from a poverty-stricken country to one of the fastest growing economies in the region.Guests in attendance included heads of state, former presidents, diplomats and foreign representatives. South African President Jacob Zuma was present, accompanied by International Relations Minister Maite Nkoana-Mashabane.On the streets, people waved their flags and painted their cars with African flags, while AU member country flags were displayed outside hotels and bars.Inside the huge hall where the celebrations were held, speakers stressed the need for unity and intensified efforts to render the continent free from poverty, conflict and disease.“We pledge to free our continent from malnutrition, unemployment, poverty and disease,” said AU Commission Chairperson Nkosazana Dlamini Zuma. “Let us march towards a continent that is at peace with itself,” she said, urging Africans to be part of the solutions to the continent’s problems.The two-day AU Heads of State summit, which started on Sunday, is set to approve the so-called Vision 2063 strategy, which seeks to achieve an integrated, prosperous and peaceful Africa by the year 2063.“Unemployment and poverty are still the main challenges confronting our continent, and with the 2063 vision in mind, we call on our people to ensure we rise to attain that vision,” said Dlamini Zuma.Kaunda challenged those at the helm of the continent’s politics to emulate the vision of past leaders, who founded the OAU as a vehicle to end the continent’s dependence on foreign powers.“We must be able to resolve conflicts that occur on our continent and deal with them amicably where they occur. The continent has made some strides, but for Africa to prosper, we have to solve our current problems. You are Africa’s hope.”Ethiopian Prime Minister Hailemariam Desalegn reminded his counterparts that the anniversary should not be a “self-congratulatory” platform but a moment to reflect on the successes of the past while at the same time looking for ways to respond to the challenges of the day.“We should approach these challenges with confidence knowing that we can succeed like those who came before us,” he said.South African President Jacob Zuma reminded Africa’s leaders that efforts had to be intensified to reform the governing global order.“While we rightfully celebrate the 50th anniversary, we are cognisant of the challenges we face. The road ahead to attain peace, stability and prosperity on the African continent for all her peoples is still arduous.“This calls on all leaders of the continent to sharpen their resolve and through the African Union, raise our collective voices, and confront the challenges presented by the current global dispensation.”Source: SAnews.gov.za

The National Investigation Agency (NIA) on Monday defended its stand of wanting an in-camera trial in the 2008 Malegaon blast case against Bharatiya Janta Party MP Pragya Singh Thakur and Lt. Col. Prasad Purohit, saying, “it is important to do so in the best interest of society.” On August 5, a group of journalists moved the special NIA court seeking an intervention in the NIA’s application, as an in-camera trial would bar the media from covering court proceedings and only allow the lawyers, accused and judge to be present.On August 2, the NIA had moved an application before special judge Vinod Padalkar, saying that the case involves facts having direct bearing on “communal harmony, national security and public order.”On October 30, 2018, the special court had framed charges of murder, abetment and conspiracy for the blast against Ms. Thakur, Lt. Col. Purohit, Sameer Kulkarni, Major (retired) Ramesh Upadhyay, Sudhakar Chaturvedi and Ajay Rahilkar.

MIAMI GARDENS, FL – DECEMBER 30: Jourdan Lewis #26 of the Michigan Wolverines tries to avoid the tackle of Carlos Becker III #15 of the Florida State Seminoles in the first half during the Capitol One Orange Bowl at Sun Life Stadium on December 30, 2016 in Miami Gardens, Florida. (Photo by Chris Trotman/Getty Images)Detroit’s Cass Technical High School football program sends a lot of players to college. Many of them, like cornerback Jourdan Lewis, end up playing for the in-state school: Michigan. Recently, Ohio State has been able to pluck some of the school’s talent away from the Wolverines. The Buckeyes have a threesome of Cass Tech players: sophomore defensive back Damon Webb, freshman running back Mike Weber and freshman defensive end Josh Alabi. On fall camp move-in day, those three players wore “Imported From Detroit” t-shirts. Today, at OSU’s media day, they took a picture together, which was posted to Snapchat. Lewis found the photo, screenshotted it and tweeted it out with the caption, “Bums.” Bums pic.twitter.com/ZxezCSWiMB— Jourdan Lewis (@JourdanJD) August 16, 2015Lewis is clearly just messing with his former high school teammates, who he is probably still close with. There will surely be no messing around come Nov. 28, when Michigan takes on Ohio State in Ann Arbor, Mich.
Then-sophomore shortstop/second baseman Maddy McIntyre throws the ball during a game against Michigan State April 24 at Buckeye Field. OSU won, 6-3.Credit: Shelby Lum / Photo editorDespite dropping four of its five games at the FAU Kickoff Classic, the Ohio State women’s softball team is confident its record is not indicative of its potential.OSU (1-4, 0-0) is set to continue its early season tournament schedule against Cal State Northridge Friday at the Easton Desert Classic in Las Vegas. The team is also scheduled to play Long Beach State later that day. The Buckeyes are then slated to take on No. 1 Florida and No. 10 Oregon Saturday, as well as Utah Valley Sunday.Even though facing two top 10 teams in one day is a tall order, coach Kelly Kovach Schoenly said she expects the Buckeyes to rise to the occasion.“Those kids are pretty pumped up,” Schoenly said Tuesday. “I don’t worry one bit that they’ll be up for those games.”Junior shortstop/second baseman Maddy McIntyre said the team is focused on Cal State Northridge and then will take it game by game from there.“We always have the same high level of intensity,” McIntyre said Tuesday. “We take the positives and roll with what we know we’re good at.”However, one of the things it’s working on is keeping its pitchers in longer, Schoenly said.“We are working on their stamina and reducing the amount of pitches they throw earlier in the game,” Schoenly said. “If we go at batters more aggressively earlier so (the pitchers) can last longer, that would be the No. 1 way to help.”Overall, though, McIntyre said she is pleased with where the team stands.“We’re right where we want to be,” McIntyre said. “We had a lot of players stand out (last weekend) and make some big plays for us.”One of those standout players was junior outfielder Caitlin Conrad, who finished the FAU Kickoff Classic batting 7-14, including two home runs, five RBIs, three doubles and a triple.Schoenly said after Conrad spent the majority of last season batting ninth in the lineup, she has worked hard to become one of the Buckeyes’ offensive leaders and now bats third.“She is a junior now and I feel like she has done what she needed to do to be in that situation,” Schoenly said. “We like to put all of our hot hitters together and right now, she’s there.”Defensively, Schoenly said the outfield has great communication skills and aggressiveness. Conrad is joined in the outfield by sophomore Cammi Prantl and junior Taylor Watkins.“They were diving all over the place. We had a couple of assists out there and Cammi Prantl dove head first into the fence. Taylor had four diving catches, they were unreal,” Schoenly said.As the Buckeyes begin to play more games, Schoenly expects the team to improve throughout the season.“For the pitchers to throw back-to-back-to-back days, it’s something they grow into as the season goes on. I think, for our pitchers, the more they do that, the better they get at it,” Schoenly said. “I think playing that many games helps our hitters too because they see so many different pitchers and so many different types of pitches.”OSU’s game against Cal State Northridge Friday is set for 4:30 p.m., followed by a game against Long Beach State at 6:45 p.m.
The Real Madrid boss, David Beckham came face-to-face with Jurgen Klopp as the two sides meet in Kiev in the Champions League final.The Spanish giants Real Madrid are seeking their third consecutive European title yet they the highest scorers in this year’s competition. Los Blancos are the slight favourites going into the clash and are spearheaded by the competition’s all-time top goalscorer Cristiano Ronaldo.Beckham played with Zidane at the Bernabeu for three years and in an interview between the two ahead of tomorrow’s game, the former England international admitted that he’s backing Real Madrid, according to Dailystar.“To have been successful as a player and now to be successful as the boss, the big boss, is incredible,” he said.“I just want to wish Zizou, the boss, the president, the club good luck in the Champions League final.“And please beat Liverpool, please.”Report: Origi cause Klopp injury concerns George Patchias – September 14, 2019 Divock Origi injury in today’s game against Newcastle is a cause for concern for Jurgen Klopp.Perhaps with one eye on Tuesday’s trip to Italy…Zidane is aiming to win the competition for the third time as he looks to make up for a miserable domestic season.The Frenchman also emphasized that he is not surprised by the level of success he’s experienced since taking charge.“We suffered and worked a lot to make it to the final,” he said.“There has been a lot of sacrifices, a lot of work, a lot of personal investment from everyone.“Once I decided to become a coach I thought nothing is impossible. Being a coach of Real Madrid I knew we could achieve great things.”
