At [ https://media.ccc.de/v/34c3-9064-the_ultimate_apollo_guidance_computer_talk ]. "While it might not be as exciting as the Saturn V rocket itself, the Apollo Guidance Computer (AGC) was one of the most important developments of the entire Apollo program. While comically underwhelming compared to modern hardware, the AGC was nothing short of revolutionary when it was developed in the 1960’s. Before the AGC, the smallest computers were about the size of a refrigerator and consumed hundreds of watts; both big problems if you’re trying to pack them into a relatively tiny space capsule with limited resources. Not only did the AGC get humanity to the Moon and back, but it also redefined the state of the art for microcomputers, paving the way for the desktop systems of the 1970’s.
That said, the design and operation of the AGC is downright bizarre to modern eyes; it comes from a time of limitations we can hardly fathom. With this in mind, [Michael Steil] and [Christian Hessmann] put together “The Ultimate Apollo Guidance Computer Talk” for 34C3.
This hour-long presentation walks viewers through every aspect of not only the AGC itself, but how it interacted with the Saturn V rocket and the overall lunar mission. Even if you aren’t enough of a vintage computing aficionado to appreciate the complexities of core rope memory, the presentation gives a fascinating look at the gritty details of one of humanity’s greatest achievements."

"Peering into the abyss"
By +Clint Burkinshaw www.explosiveaperture.com Climbing up to the rim of an active volcano is always an interesting experience. This one in particular erupted just three weeks before I took this shot, and was on high alert for another eruption at that moment. Climbing up to the rim, we had ash raining down on us. Once arriving up the top, it was a truly unearthly scene, made it feel as if we were exploring ruins from another world. A bizarre experience. - Clint Burkinshaw

"Carina over Lake Ballard"
Taken on Lake Ballard, Western Australia on 25/12/2017 - this image shows the signature hill that thrusts out from the dry salt lake, watched under the glow of the mighty Carina Nebula and the Southern Cross constellation. Lake Ballard is around 2 hours drive north of Kalgoorlie, with about 50km on a average dirt road (accessible by two wheel drive, which I did last year - but would recommend a 4x4).
On this night, the moon was at 40%, 20 deg elevation and descending therefore lighting up the foreground nicely - although at this brightness I had to back off alot on the exposure time to avoid whiting out the sky. Clouds were an issue as well, floating by occasionally. Fortunately, you can view this hill / lake from any angle so it was a matter of walking around such that the composition targeted a clear patch of sky.
This was a 22 panel mosaic but cropped to reveal closely the fantastic beauty of the Carina and Crux region of the sky. A tracking mount was used for the sky and turned off for the foreground. All camera and lens settings were kept the same for all panels. Stitching in PTGui, colour calibration, levels, saturation and contrast in Photoshop.
Enjoy, Will Vrbasso.

Neurologists May Have Discovered a Key Ally in the Fight Against Brain Aging
"As the number of people being diagnosed with dementia and other debilitating brain diseases is projected to grow steadily in the coming decades, doctors and researchers are not only looking for effective treatments, but also for ways to promote general brain health. As it turns out, one way to slow brain aging may not be that different from what works for our general physical health: eating salad.
Scientists at the Rush University Medical Center in Chicago monitored the diet of 960 elderly people. They discovered that participants who ate up to 1.3 servings of leafy vegetables a day performed better in tests designed to understand how the brain ages than their peers who ate no salad at all. The volunteers were in their early 80s and received a regular “food frequency questionnaire” between 2004 and 2013, along with two cognitive assessments..."

Maths (topology and stochastic analysis) & hiking (Utah)!!! What else?!
Scientists at Skolkovo Institute of Science and Technology have determined through mathematical modeling that the process of erosion optimizes the shapes of disintegrating materials.
Natural Erosion of Sandstone as Shape Optimisation:
https://www.nature.com/articles/s41598-017-17777-1.pdf
Natural arches, pillars and other exotic sandstone formations have always been attracting attention for their unusual shapes and amazing mechanical balance that leave a strong impression of intelligent design rather than the result of a stochastic process. It has been recently demonstrated that these shapes could have been the result of the negative feedback between stress and erosion that originates in fundamental laws of friction between the rock’s constituent particles. Here we present a deeper analysis of this idea and bridge it with the approaches utilized in shape and topology optimisation. It appears that the processes of natural erosion, driven by stochastic surface forces and Mohr-Coulomb law of dry friction, can be viewed within the framework of local optimisation for minimum elastic strain energy. Our hypothesis is confirmed by numerical simulations of the erosion using the topological shape optimisation model. Our work contributes to a better understanding of stochastic erosion and feasible landscape formations that could be found on Earth and beyond.

Canadian Nuclear Station Using 3D Printing and Virtual Reality to Save Money and Promote Innovation
"While many may not think about nuclear power as one of the many industries making use of 3D printing, the technology’s ability to save time and money, and offer design freedom, is actually a perfect fit for nuclear power plants. The Rosatom nuclear energy corporation developed Russia’s first industrial metal 3D printer for the nuclear industry last summer, less than a year before Siemens completed the first successful commercial installation of a 3D printed part in a nuclear power plant.
Canada’s Pickering Nuclear Station is the latest to incorporate advanced technologies, such as 3D printing and virtual reality, to save on costs, increase and promote innovation, and make money for the Ontario Power Generation (OPG)..."

What is Elizabeth most proud of? "Following through with my decision to audition for DCC. I relocated my entire life; I quit my job, I left my family, my friends and everything that was special to me, to move half way across the country and chase a dream, and a reality, that was seemingly so far-fetched! I have established a life in Texas, I am starting to plant little roots in this city, and my career is taking off in addition to becoming one of America’s Sweethearts!" #DCCOfTheWeek

"Many of the complex folded shapes that form mammalian tissues can be recreated with very simple instructions, UC San Francisco bioengineers report December 28 in the journal Developmental Cell. By patterning mechanically active mouse or human cells to thin layers of extracellular matrix fibers, the researchers could create bowls, coils, and ripples out of living tissue. The cells collaborated mechanically through a web of these fibers to fold themselves up in predictable ways, mimicking natural developmental processes.
"Development is starting to become a canvas for engineering, and by breaking the complexity of development down into simpler engineering principles, scientists are beginning to better understand, and ultimately control, the fundamental biology," says senior author Zev Gartner, part of the Center for Cellular Construction at the University of California, San Francisco. "In this case, the intrinsic ability of mechanically active cells to promote changes in tissue shape is a fantastic chassis for building complex and functional synthetic tissues."
Labs already use 3D printing or micro-molding to create 3D shapes for tissue engineering, but the final product often misses key structural features of tissues that grow according developmental programs. The Gartner lab's approach uses a precision 3D cell-patterning technology called DNA-programmed assembly of cells (DPAC) to set up an initial spatial template of a tissue that then folds itself into complex shapes in ways that replicate how tissues assemble themselves hierarchically during development.
"We're beginning to see that it's possible to break down natural developmental processes into engineering principles that we can then repurpose to build and understand tissues," says first author Alex Hughes, a postdoctoral fellow at UCSF. "It's a totally new angle in tissue engineering."
"It was astonishing to me about how well this idea worked and how simply the cells behave," Gartner says. (This idea showed us that when we reveal robust developmental design principles, what we can do with them from an engineering perspective is only limited by our imagination. Alex was able to make living constructs that shape-shifted in ways that were very close to what our simple models predicted)."
