An American non-profit organization built the first 3D-printed school in Madagascar

Thinking Huts intends to increase access to education.
Maggie Grout, who was born in a rural mountain village in China, was adopted rather young. “And I think that largely shaped my outlook through the rest of my life — knowing what poverty looks like, and how it impacts the opportunities you’re able to achieve in life. Having that allowed me to see more clearly what my purpose was in life — helping children gain access to education in underprivileged areas in the world,” she tells *IE* in an interview. Huts rely on additive manufacturing technologies to build sustainable schools. Recently, they built the first 3D-printed school in Madagascar.

How artificial intelligence can make our food safer
Posted by Shubham Ghosh Roy in categories: food, robotics/AI
Food recalls could be a thing of the past if artificial intelligence (AI) is utilized in food production, according to a recent study from UBC and the University of Guelph.
The average cost of a food recall due to bacterial or microbial contamination, like E. coli, is US$10 million according to study co-author Dr. Rickey Yada, a professor and the dean of the UBC faculty of land and food systems.
We spoke with Dr. Yada about how AI can help optimize the current systems used in the food processing industry, and how it can help make our food supply safer.

Scientists hid encryption key for Wizard of Oz text in plastic molecules
Posted by Jose Ruben Rodriguez Fuentes in categories: 3D printing, biotech/medical, chemistry, computing, encryption
It’s “a revolutionary scientific advance in molecular data storage and cryptography.”
Scientists from the University of Texas at Austin sent a letter to colleagues in Massachusetts with a secret message: an encryption key to unlock a text file of L. Frank Baum’s classic novel The Wonderful Wizard of Oz. The twist: The encryption key was hidden in a special ink laced with polymers, They described their work in a recent paper published in the journal ACS Central Science.
When it comes to alternative means for data storage and retrieval, the goal is to store data in the smallest amount of space in a durable and readable format. Among polymers, DNA has long been the front runner in that regard. As we’ve reported previously, DNA has four chemical building blocks—adenine (A), thymine (T), guanine (G), and cytosine ©—which constitute a type of code. Information can be stored in DNA by converting the data from binary code to a base-4 code and assigning it one of the four letters. A single gram of DNA can represent nearly 1 billion terabytes (1 zettabyte) of data. And the stored data can be preserved for long periods—decades, or even centuries.

Graphene synapses advance brain-like computers
Posted by Jose Ruben Rodriguez Fuentes in categories: computing, neuroscience
Computers that think more like human brains are inching closer to mainstream adoption. But many unanswered questions remain. Among the most pressing, what types of materials can serve as the best building blocks to unlock the potential of this new style of computing.
For most traditional computing devices, silicon remains the gold standard. However, there is a movement to use more flexible, efficient and environmentally friendly materials for these brain-like devices.
In a new paper, researchers from The University of Texas at Austin developed synaptic transistors for brain-like computers using the thin, flexible material graphene. These transistors are similar to synapses in the brain, that connect neurons to each other.

Amping up battery performance with black glasses grafted on micron silicon
Posted by Wise Technology in categories: energy, nanotechnology
Silicon is the second most abundant element on earth, making up a hefty 27.7% percent of the earth’s crust. Apart from its ability to create sandy beaches and clear glasses, silicon also holds the potential to make highly efficient metal ion batteries.
In a world where alternative energy storage devices like lithium-ion batteries are gaining momentum, there is a need to harness the excellent specific energy capacity of silicon as an electrode material. The commercial application of silicon-based electrode materials is often hindered due to two major reasons: 1) lack of mechanical stability arising from uncontrolled volume expansion upon lithiation, the process of combining with a lithium-ion, and 2) rapid energy fading caused by the formation of unstable solid-electrode interface (SEI) formation.
Over the years scientists have developed various advanced silicon-based negative electrodes or anode materials to overcome the aforementioned problems. The most prominent among them are silicon nanomaterials. However, silicon nanomaterials come with certain demerits, such as a large demand and supply gap, difficult and expensive synthesis process, and, most importantly, a threat of fast battery dry-up.
