SE3D Offers 3D Printing for Living Cells at CES



While 3D printers struggle to find a place in homes and offices, they’ve revolutionised the world of prototyping and the development of “one offs” within design and manufacturing. SE3D hope to push 3D printing into education and science, and Todd discusses the possibilities with Dr Mayasar Lim from SE£D.

SE3D’s printer differs from other devices through the substrate used for the models. Instead of plastic or metal, it uses organic materials to build the structure. By using plant or animal calls, the model can then be used within demonstrations, experiments and trials to show the response to, say, enzymes or therapeutic treatments.

Aimed at both education and laboratory markets, the basic printer unit is around US$4,000 and SE3D can provide a package for schools that includes curricular materials along with reagents and other materials.

TIME’s 100 Most Influential Images



Time 100 PhotosAs it’s still early Advent, it’s not quite that period between Christmas and New Year where “The Best of 2016” features grace the front page of every media outlet. Still, that hasn’t stopped TIME announcing its 100 Most Influential Images of All Time. Fortunately, TIME has done a much better job than most and this feature explores the background and impact of iconic photographs, from “The View from the Window at Le Gras” by Joseph Nicéphore Niépce to “Alan Kurdi” by Nilüfer Demir. These are the images which define the human experience for nearly two centuries; too many of the pictures show suffering and pain, but others will reassure and confirm the amazing achievements selflessly done for the benefit all.

Take some time to review the pictures, dig into their history and understand how that captured moment changed the world and perhaps directly affected you.


Belize road crew tears down 2,300 year old Mayan pyramid



Well, this is a mess than cannot be undone. While we all worried today mostly about Google I/O and what would be announced at the annual conference for geeks, news was coming out of Central American country Belize that had a much sadder note to it. It seems a road crew decided an ancient Mayan relic was in its way — or at least would provide needed gravel for a project.

According National Geographic’s Elizabeth Snodgrass “a construction company in Belize has been scooping stone out of the major pyramid at the site of Nohmul (meaning Big Mound), one of only 15 ancient Maya sites important enough to be noted on the National Geographic World Atlas”. The ruins have been dated to 300 BC, perhaps even earlier by some estimates.

Now it seems that nearly the entire main pyramid, which once stood over 60 feet tall, has been destroyed by road building crews, according to John Morris, associate director of research at Belize’s Institute of Archaeology.

Having traveled in the area just north of this site, visiting the ruins of both Tulum and Chichzen Itza, I feel for this terrible loss. The site can obviously not be restored, but hopefully such tragic events can be prevented in the future.


New Species of Acorn Worm Named After Yoda



“A long time ago, in a galaxy far, far, away….” is the familiar opening to the Star Wars movies. Somewhere in there, you will find a short, green, wise, Jedi master named Yoda. In a “galaxy” much closer to home, (far, far, under the ocean), scientists have found a new species of deep-sea acorn worms. One has been named after Yoda.

Yoda purpurata is one of three new species of acorn worms that were found by researchers during the ECOMAR research program. They used a remotely operated submersible to look for new animals that were living along the seafloor somewhere along the Mid-Atlantic Ridge between Iceland and the Azores.

The name Yoda purpurata translates to “purple Yoda”. This may sound strange, since we all know that Yoda is green, not purple. His light saber wasn’t purple either (that one belonged to Mace Windu). The new acorn worm, however, is a reddish-purple color. It has large lips that extend out from either side of its head, in a similar way to how Yoda’s ears extend out from his head. You can see some awesome pictures of Yoda purpurata (and several other acorn worms that have been found), here.

Find it, they did. Name it, they must. Inspired by a Jedi master, they were!

Bill Nye Stands up Against Creationism



Disclaimer: The opinions expressed in this post are those of the author and don’t necessarily reflect the site or it’s sponsors.

I am going to step on some toes in this article.  If you feel the need to click away then I understand.  After all I want to accommodate everyone’s beliefs, because everyone has a right to be heard.  That being said, Bill Nye, “The Science Guy”, recently made some comments that have raised a fire storm.  Bill isn’t backing down from them, and I support him 100%.

A video began circulating recently showing Nye demonizing parents for teaching anti-science to their children, specifically anti-evolution.  The video was titled, quite simply, “Creationism is not appropriate for children”.  The video has more than 4 million views, with a mix of supporters and detractors, but the vast majority have been supportive – 66,000 likes vs 13,000 dislikes.

In all seriousness, the U.S. currently has one of the worst track records for science education and creationists are largely responsible for this dismal record.  Religion has crept into our politics and states like Texas have even attempted to pass laws against the teaching of what is, in reality, a solid scientific theory.  Bare in mind that everything in science is a theory because it is always evolving as new evidence is found.  Evolution is every bit as solid of a “theory” as the theory of gravity.

Of course, religious groups have been up-in-arms over Nye’s comments with Ken Ham, who runs the Creation Museum, leading the charge.  Nye, in response, has appeared on CNN to defend his stance.  His views are no different than those of the vast majority of scientists, but he has the means to make them heard by the masses.  Sadly, Nye probably can’t change much, but if he sways just a few people away from trying to tell their children that the world is only 6,000 years old, then it will be a victory.


Robot Plays “Rock, Paper, Scissors” and Always Wins



The game “Rock, Paper, Scissors” sounds simple. Two players quickly choose one of the three potential options, and both players reveal it at the same time. Scissors beats paper, paper beats rock, and rock beats scissors. Children play this game on the recess field when trying to make a decision about something.

The game just got a whole lot tougher to win! Researchers at the Ishikawa Oku Lab at the University of Tokyo have created a robot hand that has been taught how to play “Rock, Paper, Scissors”. The robot can beat a human opponent 100% of the time. You can play the game, over and over, as many times as you like, but the robot will always win.

Why does the robot always win? The simple answer is that it wins because it has been taught how to cheat. The robot recognizes a human hand with the use of a high speed camera. It takes the computer 1 millisecond to recognize the position of the hand of its human opponent. The robot quickly detects which of the three potential choices the human player has made and then selects the option that will allow it to win the game. This happens faster than the human eye can track it.

The purpose of this robot is not only to have a high-tech way to play a children’s game. Instead, it is an example of how robots and humans can work together in a cooperative effort that involves motion detection. The robot can follow the movement of a human hand without their being a time delay before the robot moves.


TEDxBelfast 2012



TEDxBelfastAt TEDxBelfast last night I was inspired by the stories of individuals who passionately believed in an idea and then made that idea a reality. From working with autistic children to building a new arts centre, these people all made a difference. Presented in Titanic Belfast in front of the replica of the famous staircase, it was an unforgettable evening.

Titanic Staircase

As with all TED conferences, the presentations will be posted on-line but that will take a week or two before they are ready. In  the meantime, these are the speakers, their stories and how they made a difference.

David Maxwell of Tyrone Timberframes presented his work with Habitat for Humanity in building highly energy-efficient homes that have no central heating. The significant cost of fossil fuel-based energy can be a big factor in poverty and these homes can save the inhabitants over £1000 per year.

Maureen Murphy, Director of Aurion Learning, grabbed attention with the headline that 70% of training was wasted and proposed an innovative way of providing effective training using the acronym ASSAULT. One of the best bits was that of story-based approach that hooked the learner and got them more emotionally involved.

Fransuer Makula grew up in the slums of Kenya but is now a teacher in a prestigious school in Northern Ireland. Describing the harsh reality of existence as a street child, where death is commonplace, he related how the children dared to dream big. In the midst of utter poverty, these children wanted to grow up as doctors, nurses and lawyers. Fransuer established “Jengana” to help orphans, street children and schools in West Kenya.

Colleen Hardwick, billed as an urban geographer and serial entrepreneur from Vancouver, laid out the loss of personal engagement in democracy. The statistics she presented on the fall of voter turnout over the past few decades were shocking. To counteract the anonymous global nature of the web, she’s developed PlaceSpeak, a community-based website that lets local people be authenticated as stakeholders in local issues without necessarily giving up that anonymity.

Next was an absolute gem…acoustic guitar duo Declan McKerr and Andy Toman, aka Gypsy’s Wish, serenaded TEDxBelfast, equipped with a brand-new George Lowden guitar. His guitars are world-famous with owners such as Eric Clapton and Mike Oldfield. Sublime.

Following a musical theme, Chris Blake, Principal Horn with the Ulster Orchestra, talked about the work he’d done with autistic children and the therapeutic value of music. The results were truly ground-breaking, increasing the evidence between autism and musicality.

Dr Nigel Hart took us all on a trip to the peaks and Mt Everest in particular in his talk on Mountains, Medicine and Mantras. Clearly a keen mountaineer, he combined his medical training with his passion to investigate the effects of hypoxia on humans at altitude. During his climb to the top of the world, he had to rescue another climber who had collapsed. Apt for many shared endeavours, his response to the famous climbing question was not, “Because it’s there” but rather, “It’s not the height or the distance, it’s the people you travel with.”

Anne McReynolds, CEO of the Belfast Metropolitan Arts Centre, had TEDxBelfast captivated by her struggle to get a world-class arts centre built in Belfast. Starting in 1996 and finally opening in 2012, it’s an amazing story of architects and artists (“good clients get good buildings”), buildings and space. If you want to build an arts centre, Anne should be the first person you talk to.

Colin Williams of Sixteen South tackled the “Can’t Do” attitude that has often afflicted Northern Ireland with a great story of “Can Do” success. It’s likely that you’ll never have heard of Sixteen South, a children’s TV production company but if you have kids under five you’ll have heard of Sesame Tree, Big City Park, Pajanimals, and Big & Small. Working with the BBC and The Jim Henson Company, Sixteen South produces these great TV programmes here in Northern Ireland. Fantastic.
Colin’s business plan was pretty clever too. “Do some good, make some money, have some fun.” Good advice for anyone.

Chris Horn completed the speaker line-up with his inspiration for Dublin’s Science Gallery, an exhibition space that takes a creative and artistic approach to the presentation of science and related issues. By taking the traditional remit of a science museum and combining it with the changing presentation of an art gallery, the Science Gallery is an innovation in itself that has proved tremendously successful. So much so that Google recently awarded the Science Gallery $1m to setup other Galleries around the world.

Overall, it was a great evening, with inspirational speakers in a fantastic setting. Thanks also to Davy Sims and Gary Burnett and Mark Finlay for organising #TEDxBelfast.
