Movies often portray suspension bridges being destroyed (for example) but often make basic mistakes that reveal a lack of understanding of how these structures work. This article by structural engineer Alex Weinberg, P.E. aims to fix this.
Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]

Sara Hendren talks at the Eyeo Festival about how she, as an artist, came to work at an engineering college. Hendren teaches at Olin College in Needham, MA and runs the site Abler, a site about "art, adaptive technologies and prosthetics, the future of human bodies in the built environment, and related ideas." Hendren's talk name-checks the artist Claire Pentecost, who has elaborated idea of the artist as "public amateur": the learner who is motivated by love or by personal attachment, and in this case, who consents to learn in public so that the very conditions of knowledge production can be interrogated.

"Erik, photojournalist, and I have come here to try and get the measure of this place. Nevada is the uncanny locus of disparate monuments all concerned with charting deep time, leaving messages for future generations of human beings to puzzle over the meaning of: a star map, a nuclear waste repository and a clock able to keep time for 10,000 years—all of them within a few hours drive of Las Vegas through the harsh desert." -- Built For Eternity, Elmo Keep on structures designed to potentially outlast human civilization.

The Role of Writers in a STEM Obsessed Society
“As writers, it’s easy to think of how we matter to literature classrooms, but what the appointment of writers-in-residence in hospitals, history classrooms, foreign language learning spaces, and cooking schools reminds us is that we are relevant wherever there is humanity—which is to say, wherever humans are with their stories. Writing is healing. Writing is art. Writing is learning. As such, writing across the disciplines matters. Many models of artist residencies depend upon the retreat model, wherein the artist sequesters herself away with a small community of other artists. While these models have value, especially when considering how solitude relates to the creative process, it’s heartening to me to see more models catch on that value the place of the writer in society, rather than hidden away from it.”

The last remaining Inca rope bridge is the Q'eswachaka, spanning the Apurimac River in Peru. Even though there is a modern bridge nearby, the residents of the region keep the ancient tradition and skills alive by renewing the bridge annually, in June. Several family groups have each prepared a number of grass-ropes to be formed into cables at the site, others prepare mats for decking, and the reconstruction is a communal effort. In 2009 the government recognized the bridge and its maintenance as part of the cultural heritage of Peru.

As part of our special focus on innovation in Africa, we have developed a list of 40 remarkable African innovators. Actually, it’s more like 47 but we counted teams as one. Our decision to celebrate these idea creators and solution providers stems from our belief that the true wealth of Africa is not buried under its soil, but in the brains of its best minds. This list is a testament to that belief.
Dr. Yotarou Hatamura, who runs the Association for the Study of Failure, is also supervisor of the Failure Knowledge Database Project. He proposes adopting the "Failure Mandala" to promote the systematic understanding and dissemination of failures. To support this approach, he presents a compilation of 100 case studies of failure events organized by topic (also viewable as a single list of PDF files; and available in Japanese). Dr. Hatamura subsequently chaired the investigative committee into the Fukushima nuclear incident, which he discusses here.
The joke was funny because this was just a tiny, two-year college, with no engineering program. Getting into space was the last thing on the minds of these students; they were just trying to escape poverty. Next thing they knew, NASA was calling them up.
Frank Wilczek: Physics in 100 Years [pdf] - "Here I indulge in wide-ranging speculations on the shape of physics, and technology closely related to physics, over the next one hundred years.

This is Suame Magazine. A vast, open-air industrial district in Kumasi, Ghana’s second largest city. Here, 200,000 skilled workers manufacture everything from bolts to tanker trucks by hand. A million dollars passes through the factories and workshops here every day, and it’s the place where most of the country’s laborers learn their trades: the heart of Ghana’s informal economy.Photos and Story
Journalist Felix Salmon brings us up to speed on the increasingly strange and complicated saga of The Cooper Union School For The Advancement Of Science And Art, one of the last historically free schools in the US for Art, Architecture and Engineering, which may be brought down by shameless trustees, incompetent management, the State Attorney General, or pure greed.

The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]

Coding Like a Girl - sailor mercury at Medium:
"Apparently, presenting as feminine makes you look like a beginner. It is very frustrating that I will either look like not a programmer or look like a permanent beginner because I have programmed since age 8. I have basically always wanted to be a programmer. I received undergrad and grad degrees from MIT. I’ve worked as a visiting researcher in Honda’s humanoid robotics division on machine learning algorithms for ASIMO.[more inside]
"I don’t think that any of these things make me a better programmer; I list them because I am pretty sure that if i were a white man with these credentials or even less than these credentials no one would doubt my programmer status."
Scientists are developing ways to edit the DNA of tomorrow’s children. Should they stop before it’s too late?
There’s a widespread idea that “People who make things are simply different [read: better] than those who don’t.” [...] It’s not, of course, that there’s anything wrong with making (although it’s not all that clear that the world needs more stuff). The problem is the idea that the alternative to making is usually not doing nothing—it’s almost always doing things for and with other people, from the barista to the Facebook community moderator to the social worker to the surgeon. Describing oneself as a maker—regardless of what one actually or mostly does—is a way of accruing to oneself the gendered, capitalist benefits of being a person who makes products. [more inside]
The annual James Dyson Award is open to current and recent design engineering students. The winner this year is James Roberts with his inflatable incubator MOM. The device costs around £250 compared to £30,000 for modern incubators and could prevent up to 75% of fatalities in premature birth cases in the developing world.

...the implication is clear: If a human being could be engineered to have the positive version of each causal variant, they might exhibit cognitive ability which is roughly 100 standard deviations above average. This corresponds to more than 1,000 IQ points.
Crossing the Double Yellow Line
If you are like most motorists, you take the first opportunity to pass the cyclist safely, regardless of the stripe. After all, the purpose of the solid yellow line is to indicate where it is unsafe to pass, and the purpose of prohibiting drivers from crossing a solid yellow line to pass another driver is to prevent unsafe passing. So if it is safe to pass, then why is the solid yellow line there in the first place?[more inside]

On July 21th, 1969 Neil Armstrong and Buzz Aldrin waited within paper thin walls on the surface of the Moon. Hours ago they had made history by being the first humans to land and walk on its surface. Now the only thing left to do was take off. All that entailed was performing the final test of the Lunar Module: launching from the lunar surface with no on-site support or possibility of fixes if something failed. [more inside]

Landon "Dadhacker" Dyer reminisces about Patching the Newton: "How do you fix bugs in a ROM, if you can’t change the image?"
The patches live in the battery protected low-power RAM of the Newton, and they’re theoretically immortal as long as power holds out. This is why the battery compartment has a wacky mechanical locking system meant to discourage people from simultaneously removing both the main and the backup batteries. It’s a byzantine contraption of sliders and buttons molded in Holy Shit Yellow, and it’s meant to scare people into being cautious.[more inside]
Ian McClatchie, the Ambivalent Engineer, reminisces about his time on the Google Street View project. "At the time I was hired, we had two copies of the first camera set, which I dubbed R1. These had been assembled by bolting five 11 megapixel CCD based book-scanning cameras (shown below) to a plywood board, and bolting that to the roof of a car, much of which was accomplished by Elliot Kroo when he was, if I'm not mistaken, 14 years old (youngest intern ever at Google). Neither R1 worked much, due to problems with the cameras, not Elliot!"
HP scaling memristor and photonic computing: "the device is essentially remembering 1s or 0s depending on which state it is in, multiplying its storage capacity. HP can build these chips with traditional semiconductor equipment and expects to be able to pack unprecedented amounts of memory—enough to store huge databases of pictures, files, and data—into a computer. In theory, that would remove the need for a conventional slow disk/fast memory system. With the Machine's main chips sitting on motherboards right next to the memristors, they can access any needed information almost instantly..." [more inside]
