Chelsea youngster’s loan spell cut short

first_imgChelsea youngster Archange Nkumu has had his loan spell at Colchester United cut short.The 19-year-old, who can play in defence or midfield, joined the League One club in October and was not due to return to Stamford Bridge until next month.But he did not play for the U’s first team and was hampered by injury problems, prompting Colchester boss Joe Dunne to end Nkumu’s time there.Earlier this season Nkumu made one appearance as a substitute during a loan spell with Yeovil.Click here for Thursday’s Chelsea quiz See also:Chelsea prospect still troubled by 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Follow West London Sport on TwitterFind us on Facebooklast_img read more

Biological Designs Worth Imitating

first_imgTaking that lesson to heart, scientists at the University of Wisconsin-Madison are using the decellularized husks of plants such as parsley, vanilla and orchids to form three-dimensional scaffolds that can then be primed and seeded with human stem cells to optimize their growth in the lab dish and, ultimately, create novel biomedical implants.DNA computers are coming along, says Live Science. Tia Ghose writes, “Computers of the Future May Be Minuscule Molecular Machines.” Inspired by DNA’s longevity and extreme storage density, scientists have already encoded the entire works of Shakespeare in the genetic molecules (see article at Evolution News and hear it on ID the Future). Now that biology has shown the way to efficient data storage, engineers at DARPA are looking at other molecules that could encode in new ways beyond silicon’s 1’s and 0’s and DNA’s A-C-T-G system, using orientation, size and color to represent additional bits of information.Power plants. Bio-engineers have been trying to replicate photosynthesis for years, but still seem to have a long way to go. Science Daily says that a Japanese team has uncovered another part of the mechanism the plant uses to break down water, “marking another step towards the potential development of artificial photosynthesis.”Algae petrol. Imagine how much better it would be to create fuel from an abundant, renewable resource: algae. The Japanese are looking at this green gold: “Microalgae can grow with light, water, carbon dioxide and a small amount of minerals, and their cells divide quickly, meaning that they can be harvested faster than land-based biomasses,” Science Daily says. “Algae can also be harvested all year round, potentially offering a more stable energy supply.”Sperm therapy. To get ingredients to a female with cancerous tumors, why not imitate one of nature’s best delivery systems? Phys.org reports that German scientists are developing steerable sperm to do just that. They coax the expert swimming cells into little iron helmets, then steer them where they want them to swim. There are problems with the concept, though; how to shed the helmets after delivery, “And then there is the problem of obtaining the sperm.” There will undoubtedly be volunteers.Borrowing from nature is an age-old theme in science.Improving on nature? An article on Phys.org claims that a new technology is “better than nature” – “artificial biofilm increases energy production in microbial fuel cells.” Well, ‘better’ is relative to the function at hand. If biofilms were meant to generate electricity, the researchers at University of Bayreuth could boast. By combining a gel substance with the bacteria, the scientists got more electrical output than previous attempts with the bacteria alone.The following six papers are more technical for those interested.Bio-inspired Murray materials for mass transfer and activity (Nature Communications). Scientists build on nature’s hierarchical designs for applications needing to move mass. Why? “Natural systems and their hierarchical organization are not only optimized and designed for durability but also have the capability to adapt to their external environment, to undergo self-repair, and to perform many highly complex functions.”Reproducing the hierarchy of disorder for Morpho-inspired, broad-angle color reflection (Nature Scientific Reports). The brilliant blue Morpho butterfly returns to the biomimetics stage in the paper. Praise for the design gets mixed with long-age credulity in the opening sentences: “Intricate structures create structural colors that can remain brilliant after millions of years of fossilization. One of the most well-known examples is the butterflies of genus Morpho whose bright, blue wings grace many famous collections, and are reported to be visible even from low-flying aircrafts [sic].”Structural features and lipid binding domain of tubulin on biomimetic mitochondrial membranes (PNAS). Tubulin is not just a protein component of the cytoskeleton; it is also “a highly unexpected component of mitochondrial membranes involved in regulation of membrane permeability,” this paper says. The authors are studying its interaction with membrane proteins, knowing this will be “important for the structure-inspired design of tubulin-targeting agents.”A living mesoscopic cellular automaton made of skin scales (Nature). Theoretical cellular automata, famously conceived by John von Neumann, are realized in—of all things—lizard skin. Nature (that is, biology, not the journal) had it first. But does Nature‘s evolutionary reference compute?Here we show that in ocellated lizards a quasi-hexagonal lattice of skin scales, rather than individual chromatophore cells, establishes a green and black labyrinthine pattern of skin colour. We analysed time series of lizard scale colour dynamics over four years of their development and demonstrate that this pattern is produced by a cellular automaton (a grid of elements whose states are iterated according to a set of rules based on the states of neighbouring elements) that dynamically computes the colour states of individual mesoscopic skin scales to produce the corresponding macroscopic colour pattern. Using numerical simulations and mathematical derivation, we identify how a discrete von Neumann cellular automaton emerges from a continuous Turing reaction–diffusion system. Skin thickness variation generated by three-dimensional morphogenesis of skin scales causes the underlying reaction–diffusion dynamics to separate into microscopic and mesoscopic spatial scales, the latter generating a cellular automaton. Our study indicates that cellular automata are not merely abstract computational systems, but can directly correspond to processes generated by biological evolution.Biomimetic supercontainers for size-selective electrochemical sensing of molecular ions (Nature Scientific Reports). This paper describes how “the unique structure of spherical viruses” is  inspiring the construction of nano-containers for storage and sensing applications.Biomimetic catalytic transformation of toxic α-oxoaldehydes to high-value chiral α-hydroxythioesters using artificial glyoxalase I (Nature Communications). This paper describes attempts to mimic enzymes for maintaining handedness in pharmaceuticals. Once again, the authors tip the hat to Darwin: “Nature has evolved a wealth of proteins called enzymes that catalyse the chemical reactions necessary to sustain all life on Earth.” How nature “evolved” these capabilities is never explained.Show these articles to those who think Darwin owns science and intelligent design is religion. Nothing could be farther from the truth. If anything, the religion in these instances is Darwinism, taking it on faith that “nature” works miracles, achieving what our best scientists and engineers are struggling to imitate.Parents: get your kid a Science Fair award! Find a natural design he or she can imitate and learn about, coming up with a useful application. It will be sure to turn the judge’s heads. (Just don’t use the forbidden phrase “intelligent design” in a public school. We don’t want your kid to get Expelled.) Borrowing from nature is an age-old theme in science. Form and function go hand-in-hand in the natural world and the structures created by plants and animals are only rarely improved on by humans. If these designs are so good that intelligent minds want to mimic them, who can believe they emerged by chance?Falcon aircraft: With eyes like lasers, wings for speed, and talons for capture, a peregrine falcon swoops down unerringly for its prey at speeds approaching 200mph—even in high winds. No wonder Phys.org reports that “research work on how falcons fly is inspiring new technologies for aircraft that could contribute to their safety in the air, aerodynamics and fuel efficiency.” But even after over a century of flight design, human engineers probably won’t get close to the falcon’s abilities for another two decades. The article includes this infographic from BAE systems:The article ends with this remark by a specialist in air flow control in military aircraft: “Bio-inspiration is not a new concept; many technologies that we use every day are increasingly inspired by animals and nature.”Cheetah robot.  “University of Twente researcher Geert Folkertsma has developed a prototype cheetah robot,” Science Daily reports. “Folkertsma has dedicated four years of research and development to constructing a scaled-down robotic version of the fastest land animal in the world, with a view to replicating its movements.” To try to replicate the cat’s movements, the PhD student “studied extensive video footage of cheetahs,” the article says.Honeybee cleaners. The life of a honeybee seems like it would be a messy job: getting covered with pollen dust all the day long, even in the eyes. And yet they keep their hairs neat and clean. How? The spacing of the hairs seems to be a key, says Phys.org. The Bioneers at Georgia Tech are onto the case. They found that bees also come equipped with cleaning tools and the training to use them.“Bees have a preprogrammed cleaning routine that doesn’t vary,” said Marguerite Matherne, a Ph.D. student in the George W. Woodruff School of Mechanical Engineering. “Even if they’re not very dirty in the first place, bees always swipe their eyes a dozen times, six times per leg. The first swipe is the most efficient, and they never have to brush the same area of the eye twice.”A mechanical engineer at the school says, “Our findings may also be used to create mechanical designs that help keep micro and nanostructured surfaces clean.”Honeybee robot eyes: Speaking of honeybees, Science Daily says, “Honey bees have sharper eyesight than we thought.” They didn’t specify who “we” is, but they quickly inspire the reader with details about how scientists at the University of Adelaide are applying the new knowledge to the design of sharper eyes for robots. “Bees have much better vision than was previously known, offering new insights into the lives of honey bees, and new opportunities for translating this knowledge into fields such as robot vision, outlines a new study.”Fern batteries. Storing energy from solar cells is a major challenge. You can’t charge the cells at night, so how do you maintain the day’s energy collection? Scientists at RMIT University (Australia) are looking to Americans for answers – to American fern plants, that is – for “bio-inspired” answers to fast charging. The secret is in fractals: subdivisions of subdivisions of subdivisions in the leaves of the western swordfern. “Our electrode is based on these fractal shapes – which are self-replicating, like the mini structures within snowflakes – and we’ve used this naturally-efficient design to improve solar energy storage at a nano level,” they say. The fern-mimic electrode could “boost the capacity of existing integrable storage technologies by 3000 per cent. Watch for it in smartphones, laptops, cars, and buildings.Seaweed superconductors. Speaking of energy storage, ditch the graphite. Cease the lithium-ion pollution. There’s a greener way: use seaweed, say American scientists. Phys.org explains that when chelated, seaweed takes on an egg-box structure that magnifies the energy storage potential of batteries. “Testing showed that the seaweed-derived material had a large reversible capacity of 625 milliampere hours per gram (mAhg-1), which is considerably more than the 372 mAhg-1 capacity of traditional graphite anodes for lithium-ion batteries,” the article says. This could double the range of electric cars, while exploiting a cheap, renewable resource.Bat sonar. Echolocation in a certain species of bat seems to get enhanced when they wiggle their noses and ears. The evidence seems clear; bats have “extraordinary accuracy” at finding what they need in the dark. Virginia Tech engineers have taken notice, wondering if that could improve man-made sonar systems. The techs built a model with the new wiggle technique and found that it improved signal to noise by a factor of 100 to 1000. “Bat echolocation is one of nature’s remarkable achievements in navigation,” the article on Phys.org says, making this interesting admission: “That suggests that bolstering sensor capability by using a dynamic, mobile emitter and receiver should be translatable to engineered systems less complex than real bats, improving the navigation of autonomous drones and the accuracy of devices for speech recognition.”For Bat Appreciation Day (April 17), National Geographic posted “16 Incredible Pictures Show the Beauty of Bats.”Parsley scaffolds. Getting stem cells to grow where you want them is a challenge. Phys.org explains how some scientists are succeeding with plant materials. In the process, the scientists make a good statement about the value of living models:center_img (Visited 242 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

7 Ways to Make Your Corporate Videos Exciting and Fun

first_imgCorporate video doesn’t have to suck the life out of the room. Here are seven simple ways to make your corporate video as entertaining as it is informative!Cover image via ShutterstockCorporate video production has been a mainstay of the film and video production world for as long as cameras have been around. However, for almost just as long, they have suffered a negative reputation as unimaginative, uninspired, and downright boring to watch, shoot, or edit. That does not have to be the case.Sure, they often feature subjects, people, and companies that are not usually the most interesting or extreme, but with the right tricks, you can make your corporate videos fun again. If you still have soul enough to be up for the challenge, here are seven ways to make your corporate videos exciting, fun, and wildly watchable. 1. Animate LogosIn this day and age, knowing that some videos still have flat, non-animated logo reveals at their beginnings and ends is kind of ridiculous.For those who think a logo card fading in from black or white is still an acceptable way to grab your audience’s attention, well, you’re wrong. You’re actually losing your audience from the get-go. Aside from a plethora of tutorials available online that show you how to create animated logos, there are several free and cheap options available on this site alone (like the one featured above). You’ll find a few more resources below. Use them!3 FREE Animated Logo RevealsFree Logo Reveals and Animated FontsBest Animated Logo Reveal Tutorials2. Use After Effects TemplatesAlong with an animated logo reveal, using a full After Effects template throughout your corporate video can make a world of difference in style and storytelling. A good AE pack will feature eye-catching logo reveals, lower thirds, slide animations, animated fonts, and customizable colors, all of which can be dragged and dropped into your original footage with ease. Here are some resources below, or just head straight to RocketStock and browse their selection online.9 FREE After Effects Templates10 MORE FREE After Effects TemplatesTypography After Effects Templates3. Get Your Subjects Out of White SpaceImage via VimeoThe white cyc wall was all the rage after Apple’s successful run of minimalist commercials — however, it’s become somewhat of the norm in corporate videos ever since. While not necessarily a bad thing in the right circumstances, if you’re looking to give your videos a boost, try taking out the shots that literally offer nothing besides their subjects. Offices may not be sexy, but bringing subjects to life creatively in their actual workspaces and environments can give your videos an instant boost.4. Use Better Stock FootageWhether you’re using it for a pick-up shot or editing a full video off a stock budget, there are times when you need to call upon some dynamic stock footage to show corporate synergy and collaboration.Sure, there are almost as many places to get stock assets as there are miscellaneous shots of workers pointing at white boards, but that doesn’t mean you can’t find quality. Using a service like Shutterstock is a great way to get your video to stand out.5. Try to Avoid Flat Compositions and Straight LinesImage via BTV Business TelevisionWhen shooting corporate video, it’s important to remind yourself that you’re already down in the count against boring an audience. Filming for convenience (i.e. setting an interview against a wall for minimal set dressing) may be a common urge — but you should resist that urge when possible.It might not look like a big difference, but the image above at the very least gives some depth in space and color, as well as several different line planes to direct the eye back to the subject — all helpful devices in giving your audience a reason to keep watching.6. Minimize Corporate BuzzwordsVideo via AvayaThis may be easier said than done (following the next step listed below might help), but one of the biggest flaws in the realm of corporate video is the amount of buzzspeak, buzzwords, and industry terms that — while helpful to those with explicit knowledge — can instantly take any bystander or less business-savvy viewer out of the video. If you hear one of these words dropped in an interview, make a point to get the speaker to explain things in a more rudimentary fashion.7. Have Conversations, Not ScriptsImage via Black Label Film StudioWhich brings us to our final tip. Some videos need to be tightly scripted — like whiteboards or animated pieces — but for those that rely on corporate employees talking into the camera, scripts can be devastating when read poorly and unconfidently.One of the best ways to entice the best out of your subjects is to get them talking to you in a conversational way, straying away from rigid, scripted reciting of information. Get them comfortable in a spot in the room and focused away from the camera. If they’re any good at their jobs, they’ll usually be excited to talk about it — just, you know, to another person, not a camera lens.How do you keep your corporate videos from boring the audience?

How You Waste Time

first_imgThere are a lot of ways to waste the one completely finite, non-renewable resource that is your time. Some things that feel like work are not work at all. Other things that you pretend will improve your work are really just distractions.Looking for ShortcutsThe time you spend looking for shortcuts is time you could have spent doing the actual task itself. You can easily spend more time working on trying to get out of the work you need to do than the time it takes to actually do that work.It’s nice to have clean lines, to have processes, and to be efficient. But if it takes more time to manage those systems than it does to do the work, those systems are not really shortcuts.Cleaning Your DeskCleaning your desk is usually a way to procrastinate and avoid something you really should be doing.The problem with cleaning your desk is that it gives you a sense of accomplishment, but it does nothing to move your closer to your goals. You would be better off getting your most important tasks completed with a messy desk than you would be getting nothing important done with a pristine workspace.Filing Your EmailThere is no reason to create nested folders inside nested folders. In fact, there is no reason to file your email in nested folders at all.Outlook has a great search engine. So does Gmail. So does Mail.app. In fact, all modern email software offerings have amazing search capabilities. Scrolling through your search results is faster than spending hours building a meticulous folder structure. And it’s faster.Working SmarterIf working smarter means spending countless hours setting up your systems, deciding to try something new, and then setting up new systems to see if you can gain a few minutes of efficiency, then don’t work smarter (I am a case study here, so I know what it is I speak of).One of the smartest ways you can work is to simply do the most important thing you need to do first each day. Working hard on what’s important is better than working smarter if that means you aren’t doing what needs to be done.Most of the time you spend on the Internet and Social Media is a serious waste of your time. So is most of the time you spend watching television.If you value your time, don’t waste it. You have as much as you have and no more.last_img read more

Deaf Sports Day A Success

first_imgOn Wednesday, 19 June, the third annual Active Deaf Kids Sports Day took place at Belconnen Stadium, Canberra, with the event attended by Federal Minister for Sport, Kate Lundy.The day looked to raise awareness of Deaf Sports Australia and encourage children with hearing impairments to participate in sport. The day allowed the children that attended to participate in various sports clinics, including one run by Touch Football ACT.Senator Lundy gave a short speech over morning tea which recognised Touch Football ACT, along with several other sporting organisations, for their work with Deaf Sports Australia.She also implored the kids present to get involved in sport, pointing towards both the health and friendship advantages that participating brings.“[There are] wonderful benefits of playing sport. Being fit and active is part of it, but also sport is something that unites us all,” she said.The event was also the forum for an announcement that $60,000 extra funding would be put forward by the Federal Government to go towards deaf sports stars attending the Deaf Olympics.Related LinksDeaf Sports Daylast_img read more
