The bigger the animal, the more weight it has to carry. How can large animals maintain strong bones without making them heavier? It turns out all animals have struts in their bones called trabeculae, but the larger the animal, the fewer, stronger, and farther apart are the struts. This new finding is leading to ideas that may improve your car. PhysOrg reported on a team from Imperial College London and the Royal Veterinary College that was curious about bone structure in various mammals. Looking at femurs from 90 different species of mammals, reptiles and birds, they “found that trabeculae, typically found near joints, have different geometry depending on the size of the species.” This was news to them. Dr. Michael Doube at Imperial College London said,“Scientists had not previously known that the structure of trabeculae varied, or scaled up, depending on the size of the animal. We assumed that trabeculae would be important in supporting the weight of larger creatures such as Asian elephants, which can weigh more than three tonnes. However, we were surprised to find that animals that have comparatively lighter loads, such as the Etruscan shrew, weighing three grams, also has trabeculae supporting its tiny body. Our study is helping us to see how the remarkable geometry of trabeculae supports loads in all creatures, no matter how big or small they are.”In addition, they found that the mass of bone per unit volume was roughly constant in big and small animals, but “the trabeculae in bigger animals were thicker, further apart and less numerous.” Moving from observation to explanation, they reasoned that “the big trabecular struts inside the bones of larger animals help to support their heavier load without the need for thicker and denser bones. Using this structure saves valuable energy in larger animals because they do not have to grow, maintain and carry extra bone tissue around with them.” Neat idea. From explanation they moved to application:The scientists say new structural materials could be developed, which are inspired by geometry inside femurs. These materials would contain a lattice work of stiff foam that would be reinforced in certain areas, depending on the load being exerted on that particular section. This type of material could be used in car bodywork, only being reinforced in areas of the car where loads are heaviest. This could make cars lighter and more fuel efficient.A capital idea, worthy of stimulus by some entrepreneur. The scientists delved deeper into their biomimetic hunch and generated 200 computer models of “virtual bones,” giving their open-source code, named BoneJ, to anyone who wants to download it (see BoneJ.org). About 1500 downloads from 250 institutes and organizations have taken a look at it. Some of them might have great ideas for lightweight aircraft and automobiles. Think of the slogans: Tough as an elephant or Built to fly like a bird. Now that they understand bone structure better, the team wants to study animal motion and joints “to understand the relationship between how animals walk and bone structure.” What might come of that? Understanding bone deformities, for one thing; reconstructing the movement patterns of extinct species, for another. Their research was published in the Proceedings of the Royal Society B.Bravo! Great science with no evolution! We wish to praise researchers who get the best aspects of science right: observation, explanation, and application to help improve our lives. Sir Francis Bacon stressed that you will know good science (like good character) by its fruits. Biomimetics again shows how a design-focused science not only leads to understanding, but to practical benefits. We called this “design-focused science” but lest Eugenie and Rick Dawk have a fit, there was no need to mention God, Creator, or religion in this project. There was, however, an unspoken assumption that animal bones are well designed for what they do (go back and read the quotes for clues). Was that a science-stopper? Clearly not. It would have been so tempting for the reporter to toss in the Darwin fogma, claiming that animals evolved these amazing optimal solutions by blind chance. But fogma not only blinds, it stinks. Who needs useless smoke? Who needs to hear tall tales, like notions that vastly different animals all converged on the same solution to optimize strength per unit mass? Clear the air, stick to the observations, and make the theory do something helpful. Observation – explanation – application: that is classical science. It worked for Faraday, it’s fair for our-a-day.

29 July 2013Deputy President Kgalema Motlanthe and his delegation of ministers swapped suits for overalls on Saturday morning during a war on poverty campaign visit to the Nelson Mandela Metropolitan Municipality in the Eastern Cape.The delegation visited four projects, inspecting the construction of a house in Chatty, visiting a local resource centre, painting a newly built house, and handing over furniture and groceries to a disabled 95-year-old man.The first stop of the delegation was a construction site where they joined workers building a house at stand No 12727 in Chatty.The construction project is a partnership between the Eastern Cape Department of Human Settlements, the municipality and the Housing Development Agency. The R110-million project is expected to be completed in 2014.Nicolas Tsweu of the Housing Development Agency said there would be 1 380 new houses built between now and March 2014. Over 500 houses have been completed and occupied since construction started in September 2012. An additional 1 060 houses will be built in phase 3 of the project.The delegation then visited the Helenville Resource Centre where they undertook a walk-about to see the building progress of the centre.They were then taken to a newly built house in Missionvale where a family of six is expected to move in during the first week of August.The new owner, 34-year-old Mbulelo Jamela, said the new house would restore his family’s dignity and enable him to raise his children in a decent home.The delegation then visited a 95-year-old disabled man who had been staying alone in a house. The house had been in a dilapidated state, without a bed or furniture, before various government departments contributed to its upgrading.Director-general in the Presidency Cassius Lubisi said that although upgrading the house might seem like a drop in the ocean, it would go a long way to restoring the dignity of the old man.The delegation concluded their campaign with a community meeting in which community members raised issues calling for government attention.Source: SAnews.gov.za
Looking around the mobile industry, from Apple to Palm to HTC and Motorola – it’s clear that pinch-to-zoom technology has become a standard and popular way for users to interact with their mobile phones. Likewise, Android users can now truly benefit from this capability with the availability of Android 2.1, which powers a new class of devices with larger touchscreens and more interactive features. Unlike past devices, these phones have the processing power to deliver pinch-to-zoom, while still providing a great user experience. Based on these new capabilities and numerous requests from Android users, we decided to provide pinch-to-zoom capabilities with this new over-the-air software update for Nexus One devices. More Updates: Google Navigation, Google Goggles, Fix for 3G ConnectivityIn addition to the new multitouch functionality, this update will also bring significant new features to the Google Maps application. Starred items and search suggestions will now be synchronized with maps.google.com, for example. In addition, Google Navigation – Google’s turn-by-turn GPS app – will now get a night mode that automatically changes the colors on your screen at night to make the screen easier to read.Google will also now ship Google Goggles as a default application on the Nexus One. Google Goggles is a surprisingly useful tool that allows you to take pictures of landmarks to initiate a search, for example, or to scan business cards and automatically populate Google Contacts with this data.Early adopters of the Nexus One often complained about issues with 3G connectivity. According to Google, this new update should improve 3G connectivity on the phone. 8 Best WordPress Hosting Solutions on the Market Tags:#Google#news#web Why Tech Companies Need Simpler Terms of Servic… frederic lardinois When Google launched the Nexus One Android phone a few weeks ago, support for multitouch gestures like pinch-to-zoom was mysteriously missing from the phone’s feature set in the United States. Starting today, however, Google will begin to ship an over-the-air software update to all Nexus One phones in the U.S. that will enable multitouch pinch-and-zoom functionality in the browser, gallery and maps application. Until now, Nexus One owners had to resort to a hack to enable multitouch on their phones.Google plans to roll this update out slowly. All Nexus One owners should receive a notification about the availability of the update for their phone by the end of the week.Why Now?Oddly enough, Nexus One (and Motorola Droid) users outside of the U.S. have always been able to make use of these multitouch features by default. It’s not clear why Google decided to enable multitouch on the Nexus One now, but we have asked Google for a statement and will update this post once we hear from them.Update: We just heard back from a Google spokesperson. Here is Google’s official reasoning behind making this change now: A Web Developer’s New Best Friend is the AI Wai… Related Posts Top Reasons to Go With Managed WordPress Hosting
If you’re looking to speed up your video editing work check out the Kickstarter funded CTRL+Console control surface – now available on iPad.Earlier this year we first reported on CTRL+Console in a roundup of video editing controllers. At the time the application was still in development, after having raised a whopping $40,000 on Kickstarter in the fall of 2012. Fast forward, and CTRL+Console is now available for public release!Created on the premise that keyboards were made for typing not video editing, CTRL+Console aims to be a more intuitive controller for video editing. The app is gesture based, which lets you keep your eyes on the video footage instead of down on your iPad.Released as a FREE download through the iTunes store, the free version of CTRL+Console is a basic Quicktime video controller. To bump up the app for video editing functionality you’ll need to upgrade via an in-app purchase of $29.99. The editing controller works with Final Cut Pro 7, Final Cut Pro X and Adobe Premiere Pro (version 5 through CC). If you’ve never used a video editing editing controller before you can give it a shot without a major financial commitment – unlike many physical controllers are prohibitively expensive (like the Lightworks controller at $2,000+). The controller works with video editing apps running on both Mac and Windows based machines.To download the in-app purchase of just the Premiere Pro and Final Cut Pro controller (basic playback functionality) you’ll only part with $4.99. You really can’t go wrong with that price…even if only to impress your client with your snazzy new gadget.Get more info on the CTRL+Console site.
A rape and acid attack survivor of the Dalit community was forced to drink acid while she was travelling on a train to Lucknow on Thursday. The police on Friday arrested two men in connection with the incident. The woman was admitted to the trauma centre of the King George’s Medical College.Chief Minister Yogi Adityanath visited her and promised swift action against the culprits. “Necessary action will be taken soon,” he tweeted soon after his visit. He also directed the police to provide security to the victim, while announcing ₹1 lakh assistance to her.In 2009, Bhondhu Singh and Guddu allegedly gang-raped her over a property dispute at her home at Unchahar in Rae Bareli and on December 25, 2013 attacked her with acid.On March 10, she had gone home to Rae Bareli to see her daughter, who is appearing for Board examinations. On Thursday morning, when she was returning to Lucknow by the Ganga-Gomti Express, the two persons attacked her and forced her to drink acid at the Mohanlalganj railway station, police said. Colleagues of the victim, who works at a cafe here, alleged that she was forced to drink acid by the accused so that she would not be able to raise her voice against them.A case was registered against the two persons at the Government Railway Police (GRP) station Charbagh under Section 326 (voluntarily causing grievous hurt by dangerous weapons) and 3(2)5 of the SC/ST Act.Selfies invite flakFour RPF (Railway Protection Force) jawans were suspended for negligence in duty. The police has also ordered action against three women constables after they clicked selfies with the victim by her hospital bed. The pictures were widely circulated on social media.A. Satish Ganesh, Inspector General Police (IGP)-Lucknow Zone, termed the three constables “insensitive” and directed the Deputy Inspector General (DIG) and the Senior Superintendent Police (SSP), Lucknow, to take action. Police ignored pleaThe victim’s colleagues alleged negligence on the part of the police, saying the woman had sought police protection in the past due to threats received by her but officials did not pay heed to it.According to NGO Stop Acid Attacks, the victim was attacked in 2009 by the accused after she filed a complaint soon after the rape, and on December 25, 2013, they made the acid attack on her. She also received a fresh threat letter on January 18, after which the police and administration assured help and security.
Speedster Umar Gul on Monday upped the ante ahead of the much-anticipated India-Pakistan World Cup semifinal clash, saying that his side has the edge in bowling attack and would look to rip through the home side’s much vaunted top order to stop them on their tracks.He said Wednesday’s match would be the battle between India’s batting and Pakistan’s bowling and his side are primed to end the four-match losing streak against their arch-rivals in the World Cup.”Their (India’s) batting line-up is very strong but our bowling is very good and equally up to the task. (Skipper Shahid) Afridi is the leading wicket-taker. We have a bit of an advantage with our bowling but I am happy with the way the batsmen played in the quarterfinal,” Gul told reporters after his team’s two-hour practice session.”The first three wickets (of India) are very crucial for us. They (India) are depending on the top-three. I am in good form and am looking for these three wickets,” said Gul, who has taken 14 wickets so far in the tournament, when asked about the plans of his team to tackle the explosive duo of Tendulkar and Sehwag.Indian captain Mahendra Singh Dhoni had said that from the perspective of cricket fans, the India-Pakistan match is bigger than the final and Gul agreed with it.”What he (Dhoni) said must have been not from his side but from the expectations of Indian people. From a player’s perspective, no one would say this is bigger than the final. Our people also feel that we must beat India in each match. So from that perspective, it is a final for us too and we hope we can play well and beat India,” Gul said.advertisement”Whether it is a knockout match or a league match, any match against India is a big match always, a high-pressure match. The last time we played here, we chased 327 but it depends on how the wicket behaves. The average good score here will be 270-280,” he said.Pakistan have never won against India in a World Cup tie though they have beaten them at Mohali on previous two occasions, and Gul said history will have no bearing in tomorrow’s match and his side would be looking to end the jinx.”Hopefully, we will play good cricket and try and do what we have not done till now. Semifinal is a big match, big opportunity because both bowlers and batsmen are in good form.So we are hoping for the best,” Gul said.”The team morale is very high. I am hopeful the batting will also click and if we get a similar start like in the quarterfinals, I am sure we will do well,” he said
