Why Can’t Scientists Achieve Nature’s Designs?

first_imgBiomimetics has been big for years now, but scientists are still a long way from catching up to biology’s engineering.ROBOTICSStanford researchers study birds to improve how robots land (Stanford University). Have you ever owned a parakeet? You watch it flitter about in its cage, jumping from perch to perch, even clinging to the wires of the cage. Engineers at one of the most prestigious universities in America can’t build something that can do that. They can only watch the living bird in wonder, and take slow-motion movies, trying to figure it out. They’d like to do it, because they could make better robots.“Modern aerial robots usually need either a runway or a flat surface for easy takeoff and landing. For a bird, almost everywhere is a potential landing spot, even in cities,” said Chin, who is part of the lab of David Lentink, assistant professor of mechanical engineering. “We really wanted to understand how they accomplish that and the dynamics and forces that are involved.”Even the most advanced robots come nowhere near the grasping ability of animals when dealing with objects of varying shapes, sizes and textures. So, the researchers gathered data about how Gary [a parakeet] and two other birds land on different kinds of surfaces, including a variety of natural perches and artificial perches covered in foam, sandpaper and Teflon.“This is not unlike asking an Olympic gymnast to land on Teflon-covered high bars without chalking their hands,” said Lentink, who is senior author of the paper. Yet, the parrotlets made what seems almost impossible for a human look effortless.ENERGYNature offers potential for endless renewable fuel supplies (Australian National University). Civilization’s energy problems and climate fears could be solved if we could just do what plants do: split water. Science has been studying photosynthesis for decades. Why is it so hard?Lead researcher Dr Nick Cox said if humans could split water using cheap materials like nature did, society would have an endless supply of cheap hydrogen fuel for transportation, without carbon emissions that contribute to human-caused climate change.“Enough sunlight hits the Earth in a single hour to power all human activity for over a year,” said Dr Cox from the ANU Research School of Chemistry.“Plants use this harvested energy to split water and make complex carbohydrates which provide food for the plant to grow and thrive. This process also enriches our atmosphere with oxygen for animals, including humans, to breathe.“Copying this process from nature would lead to new and improved renewable energy storage technologies.”We want it, so let’s do it. Why the delay? Even photosynthetic bacteria have solved this physics problem. What’s the matter? Why can’t the geniuses in the world’s university do what a microbe or a leaf does?It’s not for lack of trying, but progress is slow. The press release boasts that ANU scientists at the Energy Change Institute have “cracked a key step” in the process. They found an enzyme that “stretches like a concertina” at a key step. This change “enables the orderly uptake of water to begin the splitting process,” they say. Well, that’s nice to know. But it only reveals that scientists have not even started getting into position to begin to commence building a working photosynthesis machine to harvest the plenteous sunlight striking our planet.COMPOSITESNew bio-inspired technology is poised to disrupt the composites industry (UC Riverside). Composites are materials made out of multiple ingredients designed for certain purposes. Materials science has a long history going back to ancient civilizations. For thousands of years, though, no human engineer has matched biological materials for both hardness, resistance to cracking and light weight. Bones, teeth and mother-of-pearl are examples. The mantis shrimp, with its glass-shattering club, adds a special touch: Scientists at UCR noticed a helical shape of wrapping around its “fist” that protects it.In the mantis shrimp, the helicoid prevents cracks from growing and ultimately dissipates significant amounts of energy from strikes to avoid catastrophic failure. It achieves immense impact resistance without adding unnecessary weight. Kisailus and his team discovered manufacturing ultrastrong composite materials and components using this helicoid structure results in lighter, tougher, and more impact-resistant products.Helicoid Industries hopes to sublicense the technology to the sporting goods, wind turbine, aerospace, auto parts, defense, and industrial components industries. The impact in the sporting goods industry could be significant, where weight of equipment is an issue.UCR scientists are obtaining a $5 million loan to begin commercialization of their helicoid material. Nature’s composites have a significant advantage over man’s feeble attempts at imitation: they renew and rebuild themselves throughout the lifetime of the organism. They can also reduce all the programming instructions for building structures like nacre or the mantis shrimp’s club into digital code that can draw in molecules from the environment and build new ones (i.e., baby mantis shrimp).The tone of this entry isn’t intended to disparage scientists trying to achieve success in robotics, photosynthesis and materials; more power to them! Their incremental steps are impressive. It’s intended, rather, to show the superiority of nature’s designs. If our brightest-brained scientists can’t do what plants, shrimp and birds can do, who is to argue that those organisms just happened?And yet, that’s what the materialist consensus believes! Two of these three examples (out of many) are polluted with Darwinist mythoids, stated as fact-free BAD assertions. The Stanford team says they are “studying natural systems that have evolved over millions of years” – who are they kidding? The UCR team says, “Millions of years ago, the ‘smasher’ mantis shrimp, one of nature’s feistiest predators, evolved an internal structure to protect the hammer-like club it uses to pulverize prey with incredible speed and force.” Oh good grief.To their credit, the Australia team refrained from such silliness, both in the press release and PNAS paper. That goes to show that Darwin mythoids are superfluous to papers on biological designs. Complain to the perpetrators until they stop treating the rest of us like Darwine drunkards.(Visited 274 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

The Mash Up radio host learns from listeners

first_imgPoets and musicians collaborate on The Mash Up, a weekly SAfm radio show. Between them and the audience, they teach the host and listeners about South Africa’s musical history.Naledi Moleo, host of The Mash Up, says the first show was broadcast on 13 August 2016. It was nominated for Best Music show in the 2017 Liberty Radio Awards in April. (Image supplied)Melissa JavanTo learn about South African music from the listeners and the artists in studio is one of the benefits of hosting The Mash Up radio show on SA FM Radio, says Naledi Moleo.“Songs like Jikijela by Letta Mbulu and Naughty Little Flea by Miriam Makeba are songs we would never have sourced and played had it not been for the listeners and artists who have requested real South African classics,” she adds.The Mash Up, explains Moleo, is a weekly hour-long show broadcast on Saturdays. It features live poetry and music by renowned and upcoming South African poets and musicians. “Each week, The Mash Up will bring together a poet and a musician. Through interviews, live poetry and music performances, they collaborate by ‘mashing up’ their respective crafts.”The artists may also give a selection of their favourite South African songs. “The listeners will be introduced to artists from different backgrounds, ages and genres. The show is about nation building and celebrating the extraordinary talent from South Africa.“The listeners love it. I get excited especially when listeners SMS us, giving us names of musicians and poets that we should have on the show,” says Moleo.How it startedShe realised there was a major opportunity to create a platform for South African poets, says Moleo. “Poetry has the power to either make really difficult conversations more palatable or raise our awareness of injustices. More than anything, poetry can also just uplift and renew us.“I believe that South Africans really need that in this day and age. We are bombarded with so much bad news and pressure that it is necessary to reflect. I too am in need of therapy that the live music and poetry offer at the end of every long week.”It is just magical, she says, to watch two artists who have never collaborated forced to make it work live on air — they have no prior preparation. “They always come into the studio feeling completely nervous and leave on cloud nine because they are so proud of themselves.“South Africa has always been a country that enjoys music and poetry. Think of how we sing with every major event. Think of the praise poetry and official events and even traditional weddings. The Mash Up is just a reflection of how South Africans have always expressed themselves. As a talk radio host all I really am interested in is hearing those different forms of self-expression.”The collaborationsMoleo says the musicians are usually the underdogs in the industry. “Artists like Nono Nkoane, Msaki and Tribute Birdie Mboweni are immensely talented and underrated. We think it’s important to celebrate their work.“Every now and then we will also have some of the legends of the music industry. Maestros such as Lex Futshane, Vusi Mahlasela and Pops Mohamed have also graced our studio and it’s wonderful because we get to celebrate their wonderful work and share with a younger listener who perhaps hasn’t had the opportunity to interact with their work.”One of the collaborations was Tshepo Molefe and Sabelo Mthembu.#TheMashUp with @naledimoleo brings you poet @tshepomolefe942 and musician @sabelomthembu. Expect an hour of awesome live poetry and music pic.twitter.com/YtmwB6mhL3— SAfmRadio ?

(@SAfmRadio) June 24, 2017Molefe has been writing poetry for two years. “It began when I was still a student at [the University of the Witwatersrand] and I entered a poetry competition called DFL Lover + Another. There, I met a poet who goes by the name NoLiFE [or Nobody Lives ForEver] and he introduced me to a platform called Cuddle Sessions. This in turn introduced me to the Joburg poetry scene. I haven’t looked back.”According to Molefe his poetry ranges from social issues, such as alcohol abuse and miscarriage from a father’s perspective, to political commentary to his own struggles and the problems he has with his family.He describes his experience on The Mash Up as amazing.Molefe believes collaborations such as these build a better and more versatile network between artists. “What I mean by ‘more versatile network between artists’ is often we get caught up our own artistic spaces, for instance I would normally stay in and interact with my poetry circles, and not know of other creative spaces that are out there.“Such spaces would include soul singers and instrumentalists. The Mash Up kind of collaborations opens doors for artists in different fields to first know that they exist and if they would someday want to work on a joint project, provided that they like each other’s work.”Musician Mthembu agrees: “I truly enjoyed it. I wasn’t sure what to expect. But the vibe between the poet and I was great. It was the first time I collaborated with a poet.“There was an instant gel of styles.”He says collaborations teach him that artists need each other to grow. “Working together we have the capacity to achieve more as a people.”Mthembu has been in the music industry for about 10 years. “I did backing vocals for Louise Carver for about five years before releasing my solo project.”He says although he started singing in church when he was five years old, singing was not a first career choice growing up. “I enjoyed doing it very much though. It was only after participating on South Africa’s Idols in 2007 that I decided to pursue it more aggressively.Besides Carver, he has contributed backing vocals on various artists’ projects. He calls his music “Afrosoul with a touch of jazz and classical music”.You can listen to the podcasts of The Mash Up here.Would you like to use this article in your publication or on your website?

Has bone conduction returned to wearables?

first_imgCate Lawrence With the old adage everything old is new again, this certainly seems to be the case for phenomenon bone conduction. Once the darling of hearing aids, it began to show up in the consumer headphone market in the early 2000s. During this time, bone conduction headphones were marketed as safer for long-term hearing than their standard counterparts.Since then, the technology has only really begun to make its presence known again over the last few years.  In simple terms, bone conduction enables you to hear sound through the vibration of the bones of your face — usually the jaw bones and cheek bones. The sound waves are bypassing the outer and middle ear where the eardrum is located, and directly stimulating the inner ear which is our actual “hearing organ.”See also: Seniors getting helping hand from wearablesAs well as hearing aids and headphones, the technology has also been attributed to Beethoven’s ability to write music — even while hearing-impaired — through biting down on his composer’s wand that was touching the piano.Here are a few of the devices that are embedding the technology into wearable devices:SgnlIf you’ve ever had a hankering to be James Bond, your dreams can now become a reality. Innomdle Lab, the first company ever to officially spin off from Samsung Electronics have created Sgnl, a smart strap that enables users to engage in phone conversations simply by placing their finger to their ear. Whether attached to a classic watch or a smart watch, users can enable fingertip communication and a number of additional smart functions simply by replacing the watch strap. Additional smart functions include Call Reminders, Fitness Tracker and Smart Alert.Sgnl’s key technology lies in its patented Body Conduction Unit (BCU), which is capable of transmitting vibrations through the body, which then can be converted to sound. Sgnl communicates with the user’s phone through Bluetooth, and when a voice signal is received, Sgnl will generate vibrations through its BCU. These vibrations will be sent through the users’ hand to their fingertip. When users place their fingertip to their ear, the vibration echoes to create amplified sound within the closed space of their ear and they can speak through the microphone embedded in the Sgnl strap. Overall, very appealing.https://readwrite.com/wp-content/uploads/Demo_Fingertip_Phonecall.mp4 Marlen is a wearable device by Hong Kong based start-up Playtsens for swimmers. The wearable is attached to the user goggle strap at the back of the head and the second piece to the ear piece and it sends you voice feedback using a bone conduction headset, even when underwater. Your pace is reported to you as you swim with no disruption to your swim stroke.In open water swims, your swim performance is captured with GPS. In the pool, motion sensors are used when there is no GPS reception. After your swim, you can connect Marlin to your phone with Bluetooth to review your data and update configurations.It’ll be interesting to see how other wearables incorporate bone conduction. It would be easy to imagine some of these examples employed in traditionally noisy settings such as factories and warehouses. It’s also foreseeable that hearing devices and technology becomes more responsive and customizable as our rapidly aging popular sees a decrease in their hearing quality and clarity.While previous generations may have been content to suffer from poor sound quality, our connected generations are more likely to look to technology to solve the problem. Zungle sunglassesDid you know you can now listen to music through your sunglasses? Well not just any sunglasses but a pair created by Zungle containing bone conduction. These sunglasses enable the wearer to listen to music and answer telephone calls as they can be paired with a smart phone through wireless Bluetooth and a noise-cancelling microphone that lets you make and answer calls. They are chargeable via a hidden USB port.Zungle have received over $1.9 million in funding via Kickstarter, having asked for an initial $50,000.Invisio headsetsWhilst not traditionally a general consumer product, bone conduction headsets are popular in military and police occupations. The headsets are configured to work with both analog and digital radios and can be adapted to work with push-to-talk awitches. They include Kevlar-woven cables for added durability, unique whisper capability, the ability to work under eyewer or gas masks and also the ability to clearly communicate in high noise environments.Google Project AuraThe original Google Glass utilized bone conduction audio, meaning nothing needed to be placed inside the ear. This resulted in a more comfortable headset as well as great situational awareness through being still able to hear. Since Google Glass went rather quiet the division responsible, Project Aura whilst scarce in offering information is believed to be continuing their interest in bone conduction technology.Marlin GPS swimmeter Small Business Cybersecurity Threats and How to… Related Posts center_img Follow the Puck Why IoT Apps are Eating Device Interfaces Tags:#bone conduction#Connected Devices#featured#Google Glass#hearing aids#Project Aura#Sgnl#sport wearables#top#wearables#Zungle Internet of Things Makes it Easier to Steal You…last_img read more

3 Tips for Recording Long-Form DSLR Productions

first_imgIt’s doable, but it’s certainly not easy to record cinematic, long-form productions with DSLR cameras.Cover image via Shutterstock.If we could go back in time and speak with Joe DSLR (or whoever it was who invented the digital single-lens reflex camera) about his decision, I can pretty much guarantee he would not mention long-form video recording as one of his main goals.DSLRs (and many other mirrorless and digital cameras) are marvels of video capture technology, but they’re not really meant to record for long periods on end. For most long-form needs, you’ll need to look for cheaper camcorder options or a few higher-end options.However, for those looking to use their trusty prosumers (like a Canon 5D or comparable) to record long-form content, here are some ways to trick ol’ Joe DSLR into helping you get the job done.1. Maximize Recording CapabilitiesImage via Shutterstock.If you’re familiar with Canon DSLRs, you may assume that the maximum recording capabilities for your camera are 30 mins (or 25 minutes and 59 seconds) if you look at your manual. However, this is and isn’t true in a couple of ways. Yes, that’s the max time built into the camera, but if you just turn your camera on and hit record, you’ll find that your camera does a couple of things differently — and probably maxes out its recording at around 12 minutes.There are a couple of reasons for this. The biggest hindrance is that most Canon DSLRs can only record 4gb files at a time. (Newer cameras won’t stop recording at this point — they’ll simply create a new file.) This is assuming that your camera sensor doesn’t overheat. Other factors like card speed and battery life come into play as well. So what does that mean for maximizing your capabilities?To truly push your camera as far as it can go, you can do a few things. One is reduce your recording quality as much as you can (even down into SD). This will save the most in terms of card writing speed, memory, and battery life. You can also use add-on items like battery packs, or even directly power your camera through an AC adapter. It should also go without saying that you should be using the fastest card possible.2.  Hack It with Magic LanternOnce you’ve maximized your camera capabilities with the built-in software, you can further hack it by using add-on programs. (Note: using Magic Lantern and other third-party firmware voids certain camera warranties, so use at your own risk!) Magic Lantern is a popular open-source software that you can load into your camera’s firmware to gain more control. It’s probably best known as a go-to hack to get higher recording quality out of your Canon DSLRs for RAW footage. By the same token, it can also help you reduce your recording quality by decreasing H264 bitrate and framerates.Watch the 7D Magic Lantern hack video above, or read more about their add-ons here.3. Use More Than One CameraImage via Youtube.Even after maximizing your camera’s capabilities with built-in features and Magic Lantern hacks, you still may not get the full, continuous shooting capabilities you need. If you’re looking to shoot several hours of nonstop footage and would like that DSLR quality, your best bet at the end of the day may be to use more than one camera. With a solid two-camera setup you can work with your camera’s capabilities and shoot in 10-minute bursts. While one camera shoots, you can let the other one cool down and replace things like batteries and cards.The biggest trick would be finding a setup where the cameras can be close enough together to make the footage match. You’ll also get the best result out of this setup if you use two of the exact same cameras with the same lenses. However, if you must mix and match, try to be consistent in terms of sensor sizes, lens lengths, ISO, and white balance to save yourself extra work in post.For more production tips and tricks, check out some of these resources below.Filmmaking Tricks: How to Make One Camera Look Like Two3 Tips You Must Know Before Shooting a Multicam ProductionHow to Use a Third Camera on Interview Shoots5 Affordable Streaming-Ready Cameras for Your Next Live Eventlast_img read more

$100 Million Upgrading for May Pen Hospital

first_imgThe May Pen Hospital is slated to undergo a multi-million dollar upgrading and rehabilitation project this fiscal year.This was disclosed by Health Minister, Hon. Dr. Fenton Ferguson on Friday, April 12, following a tour of the Clarendon-based facility.Dr. Fergsuon said the project is estimated to cost between $96 million and $100 million, with approximately $64 million of the amount already approved by Cabinet. He said he is awaiting consent for an additional $32 million for upgrading of the chiller system at the hospital.The improvements works will entail modernisation of the hospital’s radiology department at a cost of $27.8 million, to provide digital services.A sum of $15.6 million will be spent to expand the Accident and Emergency Department and provide well-needed equipment. Already, three new air conditioning units have been acquired.In addition, some $8 million will go towards upgrading the hospital’s sewerage system, while an estimated $5.4 million is earmarked for improving security services, including the provision of surveillance equipment, as well as grillwork.A further $5 million will be used to improve food trolley services at the hospital, the Minister said, noting that “presently, the region is spending over $500,000 per month to deal with the disposal of food”. He noted that, provided there is funding, work will also be done to the hospital’s roof and road network, while the perimeter fencing will be addressed in the next fiscal year.“We have had some initial estimates in the region of $40 million and we have said to the Member of Parliament and the leaders of this institution that we are committed to the process, and our expectation is that our 2014/15 budget will see that as a priority,” he stated.Dr. Ferguson, in the meantime, informed that the Ministry has committed a sum of $1 million for a major Labour Day project at the hospital.“My special appeal is that the business sector, companies that distribute paint and other kinds of hardware material, in and around May Pen, and beyond, will come onboard for this worthy exercise,” he urged.“Many of your workers are the beneficiaries of the health care delivery system and we feel that a partnership will be a major achievement in establishing this hospital as a centre of excellence,” the Minister stated further.Accompanying Dr. Ferguson on the tour were: Mayor of Clarendon, Councillor Scean Barnswell; Member of Parliament for Central Clarendon, Mike Henry; Chairperson, Southern Regional Health Authority, Fay Bell; and Chief Executive Officer, May Pen Hospital, Nadia Nunes-Howe.By Athaliah Reynolds-Baker, JIS Reporterlast_img read more

Lithium imports crucial for Teslas Gigafactory in India

first_imgImports of Lithium are crucial for US-based electric car manufacturer Tesla Motors’ chief executive Elon Musk’s plan to set up a Gigafactory in India, as the country does not have enough reserves of the rare metal to support making of lithium-ion batteries, according to analysts.Lithium is a rare metal used in manufacturing of batteries to increase their capacity and also helpful in reducing the size of battery boxes compared to other battery technologies.”From a manufacturing-in-India perspective, the country doesn’t have any Lithium deposits, so it is going to be hard. Unless we import Lithium ore, which is available in Bolivia, Argentina and Australia, manufacturing cannot be supported in India,” Business Standard quoted Mridula Dixit, principal research scientist, Centre for Study of Science, Technology and Policy (CSTEP), as saying.However, Australia could become a major source for imports of Lithium ore, as the trade ties between the two nations have improved in the past. India has entered into an agreement with Australia for Uranium supply to its nuclear reactors.”We are not well-placed in terms of raw materials. The supply chain needs to be worked out. Also, making the batteries requires a very controlled environment,” said Dixit, who has extensive exposure to lithium-ion technologies.”Given India’s lack of expertise, I see global manufacturers bringing in their technology and manufacturing processes first, in the next five to 10 years; only after that would we be able to have local players gaining expertise and beginning to manufacture in India” Dixit added.Musk, the founder of Tesla Motors, has recently hinted at setting up a Gigafactory in India to manufacture lithium-ion batteries, taking into the problem of power shortage in the rural areas of the country, which holds a huge potential for such batteries.During his visit to the US in September, Prime Minister Narendra Modi had held discussions with Musk at the Tesla campus in Silicon Valley on the potential of having a battery making facility and other renewable energy technologies in India.Tarun Mehta, co-founder of Ather Energy, an electric vehicle start-up, sees the necessity to have  hundreds of Gigafactories in the country, as lithium-ion batteries can “compete with lead acid batteries in cost.””One Gigafactory can produce just enough cells for half a million Tesla cars. Globally, we produce 65 million cars and a lot more two-wheelers. If all of them were to go electric over the next decade or two, you are looking at 100-plus Gigafactories at least,” said Mehta.last_img read more

Two abducted one returns

first_imgMap of RajshahiUnidentified miscreants have allegedly abducted two college teachers from Charghat upazila of Rajshahi on Saturday afternoon. One of the teachers returned his home in the evening while other remains missing, their relatives said.The victims, Bazlur Rahman, lecturer of political science of Charghat Dakra Degree College, and Shafiqur Rahman Ujjal of the English department of the same college, were picked up at around 11 am while they returning home by motorbike.Eyewitnesses said they were intercepted by another motorbike in front of Anupampur High School while several other persons in a microbus picked them up. The microbus then whisked them off towards Charghat upazila sadar.Bazlur Rahman later returned home in the evening as the abductors left him at Dashuriya of Pabna district. Bazlur said, he couldn’t recognize the abductors and doesn’t have any clue as to why they were picked up.Law enforcers have denied any involvement in the incident.Officer-in-Charge of Charghat police station, Nazrul Islam told Prothom Alo that they know nothing of the incident. But the police is now searching for the abducted teacher.Deputy commander of RAB-5 Ashraful Islam also denied that they conducted any such operation.
