Meet the 13-year-old who just built a cheap Braille printer out of Legos 

Whatever you were doing in eighth grade, it probably wasn’t as awesome as what Shubham Banerjee has been up to.

The California 13-year-old wanted to know how blind people read, so he searched online and was shocked to find Braille printers cost up to $2,000.

“I know that there is a simpler way to do this.”

Power-pylons that look like looming giants

Choi + Shine, an architecture firm, has proposed modifying Iceland’s existing power-transmission pylons to turn them into looming giants whose arms are poised to reflect their positions – pylons ascending a hill will be posed as though they were scaling its slopes.

The designers claim that it can be made cost-effective through clever engineering, and that the resulting aesthetic experience will be monumental. I agree with the latter statement and am unqualified to assess the former, though Iceland has a weird and cool relationship with power, as it is ia carbon-neutral country whose electricity comes from geothermal sources.

What would be the effect of more women working in agriculture? 

“The women I met in agriculture showed a clear preference for working on organic and small farms, which are more likely than factory farms to reflect the values of animal welfare, human health and environmental sustainability." 

-Sonia Faruqi says on what she found when she spent time visiting farms in eight different countries. 

Agriculture needs more women (The Atlantic)

Researchers at MIT have developed a new method for harnessing energy generated by very small bending motions, which could be capable of harvesting power from a broader range of natural human activities such as walking and exercising.

The Fantastically Strange Origin of Most Coal on Earth

The absence of the tiniest creature can shape the world in the biggest way.

Ever wonder how coal formed?

Yet despite decades of relegation to roles as tourist attractions or advertising gimmicks, airships may be on the verge of a comeback. This resurgence will be fueled not by impractical nostalgia or fandom, but by incredible advances in airship technology that have made these craft both immeasurably safer than their predecessors, and perfect vessels for certain niche conditions. And it seems like this phoenix-like rebirth of everyone’s favorite forgotten tech might just begin in the Canadian north.

An Urbanizing Planet

The video, entitled An Urbanizing Planet, takes viewers on a stunning satellite-viewed tour around our planet. By combining more than 10 datasets, and using GIS processing software and 3D graphic applications, the video shows not only where urbanization will be most extensive, but also how the majority of the expansion will occur in areas adjacent to biodiversity hotspots.

The video was produced to present the framework of a new book Global Urbanization, Biodiversity, and Ecosystems: Challenges and Opportunities — A Global Assessment. The scientific foundation of the Cities and Biodiversity Outlook project, the book presents the world’s first assessment of how global urbanization and urban growth impact biodiversity and ecosystems. It builds on contributions by more than 200 scientists worldwide.

Spatial Agency: Other Ways of Doing Architecture

Nishat Awan

This book offers the first comprehensive overview of alternative approaches to architectural practice. At a time when many commentators are noting that alternative and richer approaches to architectural practice are required if the profession is to flourish, this book provides multiple examples from across the globe of how this has been achieved and how it might be achieved in the future. Particularly pertinent in the current economic climate, this book offers the reader new approaches to architectural practice in a changing world. It makes essential reading for any architect, aspiring or practicing.

In an experiment, two ravens had to simultaneously pull the two ends of one rope to slide a platform with two pieces of cheese into reach. If only one of them pulled, the rope would slip through the loops, leaving them with no cheese. Without any training they solved the task and cooperated successfully.

However, when one of the two birds cheated and stole the reward of its companion, the victims of such cheats immediately noticed and started defecting in further trials with the same individual.

“Such a sophisticated way of keeping your partner in check has previously only been shown in humans and chimpanzees, and is a complete novelty among birds.”
