Scientists watch bioengineered self-healing muscle tissue grow within a mouse

by Jan Belezina

Strands of engineered muscle fiber have been stained to better observe their growth within...

The living skeletal muscle tissue grown by Duke University researchers is 10 times stronger than any previously bioengineered muscles. Not only does it contract as strongly and as rapidly as the real thing but it is also capable of self-healing, both in the lab and after implantation into an animal. This has been proven beyond any doubt through a novel approach that involves peeking at the growing muscle tissue through a glass window in the back of a living mouse...

Leia On Hoth Costume

by Amy Ratcliffe

hoth leia

Some fandoms have dedicated costuming groups, and that means plenty of reference material and tutorials are online for costumes. Star Wars is a perfect example. It seems like every outfit from the saga has been carefully documented at The Padawan’s Guide. They provide images, links to tutorials and resources, and so much more. I focused on Hoth Leia since that’s my favorite costume of the self-rescuing princess and ended up at Audrey’s blog. She documented everything from making the jumpsuit to the vest to the accessories and props. Here’s what she did to dye the jumpsuit to make it more closely match the white we see on screen in The Empire Strikes Back:

We spent hours dyeing trial swatches of the cotton blend suit and silk vest in taupe and tan dye. We started with a half-teaspoon of RIT powder dye in a large washer load of water, and were down to a quarter-teaspoon by the time we quit yesterday. I had no idea the stuff was so concentrated! Scott suggested we try the liquid dye to get more consistent color, since we were using such small amounts that there was no way to know if the color grains were evenly distributed. Today we started with half as much of the liquid dye, thinking it was twice as strong as the powder, but it turned out to be only half as strong. So we went back to a half-teaspoon. The color was a lot more even and less pink than with the powder, especially on the silk.

In the final load, we upped the amount of dye another “dash” (eighth-teaspoon; Pandora’s measuring spoons are actually labeled this way!) since there would be a lot more fabric in the load. It didn’t look like dyeing; it looked like washing clothes in well-water, tinted yellow from too much iron. Still, we ran an extra rinse (I think the “dash” may have been a “pinch” too much!) before drying the jumpsuit.

A Dystopian Sci-Fi Movie Filmed Completely under the Radar in China … Starring Ai Weiwei

by Christopher Jobson

A Dystopian Sci Fi Movie Filmed Completely under the Radar in China ... Starring Ai Weiwei science fiction movies China

Just announced today, The Sand Storm is a short film directed by New York filmmaker Jason Wishnow that was shot completely under the radar in China, starring none other than dissident artist Ai Weiwei in his acting debut. How such an audacious and risky endeavor came into being is pretty mind-blowing given the heavy amount of surveillance surrounding the artist. The movie takes place in a dystopian future where Ai Weiwei plays the role of a smuggler in a world without water.

The existence of The Sand Storm was kept heavily under wraps while shooting in Beijing. Ai Weiwei has been closely watched by the government since his 2011 imprisonment and authorities still have yet to return his passport. While the short film has already been shot beginning to end, the filmmakers are raising a bit of money on Kickstarter to finish the movie and recoup some costs as crowdfunding beforehand was too risky. Had this been announced yesterday I would have assumed it was a hoax.

Whacked Recycled and Tech Fashion #WearableWednesday

by Leslie Birch

Laura Briscoe CollageMakers in Canada recently strutted their creative fashions at a show sponsored by Museum London and DHMakerBus. Blogger Shelley Long, posted some great pics and interviews on Forest City Fashionista. The piece above, by Laura Briscoe,  included many computer parts, as well as a screen. Laura was very dedicated to her piece called “Mis Communication”.

It took hours and hours.  The hardest part was prying the keys off the keyboards and then fusing them together with a blowtorch.

More glowing charm was found in the LED creations by Bernie Rohde and K La Luna. Their mini sculptures were voice activated.

Led accessories models

One piece that got some chuckles was the LED kilt by Paul Graham. Forest City Fashionista had a chance to chat with him after the show.

He offered to create customized LED lighting I could attach to the crinoline I was wearing, and I was tempted to take him up on his offer; it would give a new meaning to the the word “flashing”.

Led kilt 02

Paula Johns had the most classic and surprising “Celluloid Dress”, which combined with other elements to create an installation piece.

The dress, which is in the style of a 1950′s cocktail dress, is made of approximately 250 feet of 16mm celluloid film and nylon mesh. Battery pack operated LEDs are sewn into the dress’s underskirt to light up sections of film. In the display, John’s film, “Becoming Marilyn” (of which the dress is constructed) follows a large loop through the projector, across the ceiling to feed down into the sewing machine, and then back across to the projector. The film, which depicts the artist making herself up to look like Marilyn Monroe, is projected onto a white wall positioned behind the sewing machine.

Film dress collage

Finally, the FLORAbrella, of Adafruit fame, made an appearance with maker, Leslie Birch. She was clearly excited about the maker movement in London Ontario.

LED umbrella collage

Sometimes the best inspiration comes from what is around you. What kind of materials or spare parts do you have sitting around? People are making dresses out of beer can pull tabs and necklaces out of old Scrabble tiles. Look at everything as a potential wearable and soon you’ll create an original. Then just expect to be featured on our Wearables show. :)

Perched at the window of his Cessna 172, photographer Klaus Leidorf crisscrosses the skies above Germany while capturing images of farms, cities, industrial sites, and whatever else he discovers along his flight path, a process he refers to as “aerial archaeology.” Collectively the photos present a fascinating study of landscapes transformed by the hands of people—sometimes beautiful, sometimes frightening. Since the late 1980s Leidorf has shot thousands upon thousands of aerial photographs and currently relies on the image-stabilization technology in his Canon EOS 5D Mark III which is able to capture the detail of single tennis ball as it flies across a court. You can explore over a decade of Leidorf’s photography at much greater reslution over on Flickr. All images courtesy the artist.

BionicKangaroo – energy-efficient jump kinematics based on a natural model #robotics

by Jessica

We’ve mentioned Festo’s nature-inspired robots before but this little guy is one of our new favorites.

With the BionicKangaroo, Festo has technologically reproduced the unique way a kangaroo moves. Like its natural model, it can recover the energy when jumping, store it and efficiently use it for the next jump.

Technical implementation of a unique form of movement

On the artificial kangaroo, Festo intelligently combines pneumatic and electrical drive technology to produce a highly dynamic system. The stable jump kinematics plus the precise control technology ensure stability when jumping and landing. The consistent lightweight construction facilitates the unique jumping behaviour. The system is controlled by gestures.

Mobile energy supply on board

Festo paid particular attention to the mobile energy supply on the artificial kangaroo. For this purpose, the team even developed two different concepts – one with an integrated compressor and one with a mobile high-pressure storage device.

Neurocomic: A Graphic Novel About How the Brain Works

by Maria Popova

From the caves of memory to the castles of deception, by way of naughty neurotransmitters and giddy ganglia.

Scientists are only just beginning to understand how the brain works — from what transpires in it while we sleep to how to optimize its memory to what love does to it to how music affects it — and the rest of us fall somewhere on the spectrum between fascinated and confused when it comes to the intricate inner workings of our master-controller.

From British indie press Nobrow — who also brought us Freud’s graphic biography, those lovely illustrated chronicles of the Space Race and aviation, as well as Blexbolex’s magnificent No Man’s Land — comes Neurocomic (public library), a graphic novel about how the brain works. This remarkable collaboration between Dr. Hana Roš (and dog knows I love few things more than a female neuroscientist) and neuroscience-PhD-turned-illustrator Dr. Matteo Farinella, with support from the Wellcome Trust, explains the inner workings of the brain in delightful and illuminating black-and-white illustrations, covering everything from perception and hallucinations to memory and emotional recall to consciousness and the difference between the mind and the brain.

We take a stroll through a forest of neurons, then learn about neuroplasticity. (“This is the great power of the brain, it’s plastic!” they tell us in one of the most heartening and reassuring parts. “Once you learn something it is not set in stone, it’s continuously shaped by experience.”) We meet Pavlov and his famous studies of memory in 1897 Russia. We visit the haunting memory caves and the convoluted castles of deception.

This wonderful trailer for the film about the project, directed by Richard Wyllie, takes us behind the scenes of the duo’s marvelous collaboration and creative process:

Pair Neurocomic — which is gorgeous not only to behold but also to hold, bound in indigo fabric with silver-and-gold cover art — with the graphic biography of Charles Darwin, then dive deeper into the brain’s mysteries with the scientific riddle of left-handedness.

Before drugs are tested on humans, they first go through pre-clinical tests on animals. Because humans and animals don't have identical gastrointestinal tracts, however, the way in which the drugs are absorbed by the body often differs between the two. A scientist from the UK's University of Huddersfield hopes to address that discrepancy, with his "gut simulator." .. Continue Reading Gut simulator could bring down the costs of drug development

Calslock Portable Door Lock

by mark

I have owned this tool for approximately two years. It manually locks an inward opening door. Ideal for travelling, students or anywhere that you would want privacy and security and there is likely to be multiple copies of the door key in circulation. I am on the road most weeks and have been walked in on in several hotel rooms by people with duplicate keys. I did some research and came across portable door locks.
It will not stop a determined attacker, but that is not what it is made for. It stops someone sneaking into your room using a duplicate key or bypassing the lock. A lot of hotel rooms have security chains, but there are videos on the web showing how these can easily be defeated. It also works on doors with no locks, aslong as there is a recess in the door jam where the door catch fits you can use it.

I originally had a similar one to this that I lost. When I went to replace it they had stopped production. I tried having tried several other designs but was never happy, then came across the Calslock one. At the time I purchased they only appeared to be sold on eBay, which worried me, but having purchased one there was very good service and it is an excellent product. (Still on eBay and cheaper than their home page!)

What makes this a cool tool compared to other portable door locks is a combination of things:

- It is a very good design, slim enough to fit doors that have a very tight fit.
- Easy to operate quickly if you need to get out in an emergency.
- Very adjustable from the thinnest cheapest door to thick heavy fire doors, I have yet to come across a door that is outside it’s adjustment range.
- It is very simple, only two large parts so no small fiddly bits to lose or to go wrong.
- Finally it is cheap, only $9.95, including free postage in USA on eBay or $12.95 direct.
I have no affiliation with Calslock, but whole heartedly recommend their product.

This rare book opens 6 different ways to reveal 6 different books #ArtTuesday

by Jessica

6 way book

This is one of the coolest versions of book binding that we’ve ever seen! Via Visual News.

Book binding has seen many variations, from the iconic Penguin paperbacks to highly unusual examples like this from late 16th century Germany. It’s a variation on the dos-à-dos binding format (from the French meaning “back-to-back”). Here however, the book opens six different directions, each way revealing a different book. It seems that everyone has a tablet or a Kindle tucked away in their bag (even my 90 year old grandma), and so it sometimes comes as a surprise to remember the craftsmanship that once went along with reading.

The book, which comes from the Rogge Library in Strängnäs, features devotional texts printed in Germany during the 1550s and 1570s (including Martin Luther’s Der kleine Catechismus). Each of the books is held closed with its own ornate metal clasp, and was probably far more decorative than useful. Just imagine finding where you left off! See more images of this book and other rare examples on the National Library of Sweden’s Flickr page.

Wu-Tang Rapper GZA Delivers TED Talk About Science Education #makereducation

by Kelly

Rapper GZA of Wu-Tang Clan promotes science education in this awesome TED Talk, from Time.

“Why is the sky blue? Why is the grass green?”

The Wu-Tang Clan’s GZA, a.k.a “The Genius,” a.k.a. Gary Grice just gave a TEDxTeen Talk as the latest viral address in his campaign “to provide a model for students to communicate the information learned from their science teachers.”

As Wu-Tang’s dozen or so active members are busy finishing the iconically absurdist rap group’s 20th anniversary reunion album, it just so happens that GZA is also leading Science Genius, an “urban science initiative” that he cofounded with Rap Genius and Christopher Emdin of Columbia University’s Teachers College. The project weaves lyricism and artistic conception into the science curricula of 10 public New York City high school classrooms.

While many musical artists are known to promote public funding of arts education, GZA and his bandmates have long been obsessed with the many mind-blowing phenomena of the universe. “Why is the sky blue? Why is the grass green?” he asks. “Why is metal a conductor of electricity, and wood is not; but you’re more likely to be struck by lightning when standing under a tree?”

“These are questions that require science to answer.”

Scientists Create Biodegradable Battery That ‘Melts’ Inside The Body After Use

by Yarrow Maurer

14919-combined

An exciting new biodegradable battery unveiled by a team of scientists could have huge potential for biomedical devices. The tiny battery can be safely absorbed by the body within just three weeks and could be used in temporary devices intended to monitor tissue or deliver short term treatment. From Nature:

Their devices, described last week in Advanced Materials, use anodes of magnesium foil and cathodes of iron, molybdenum or tungsten. All these metals will slowly dissolve in the body, and their ions are biocompatible in low concentrations. The electrolyte between the two electrodes is a phosphate-buffered saline solution, and the whole system is packed up in a biodegradable polymer known as a polyanhydride.

Currents and voltages vary depending on the metal used in the cathode. A one-square-centimetre cell with a 50-micrometre-thick magnesium anode and an 8-micrometre-thick molybdenum cathode produces a steady 2.4 milliamps of current, for example. Once dissolved, the battery releases less than 9 milligrams of magnesium — roughly twice as much as a magnesium coronary artery stent that has been successfully tested in clinical trials, and a concentration that is unlikely to cause problems in the body, says Rogers. “Almost all of the key building blocks are now available” to produce self-powered, biodegradable implants, he says.

All versions can maintain a steady output for more than a day, but not much longer. The team hopes to improve the batteries’ power per unit weight — known as power density — by patterning the surface of the magnesium foil to increase its surface area, which should enhance its reactivity. The authors estimate that a battery measuring 0.25 cm2 and just one micrometre thick could realistically power a wireless implantable sensor for a day.
