Every year, an estimated $80 billion of valuable metals are discarded in consumer and industrial waste streams (known as the urban mine). This is all the more regrettable since humanity’s appetite for the electronics that use these metals is ever-growing, leading to increased needs to mine more metals. But traditional mining takes a real toll […]

As the world’s population grows, so does the need for proteins to ensure healthy diets. But current practices to produce protein, such as meat, poultry, fish, eggs, and dairy products, are unsustainable and harmful for the environment. Whether red or white, meats require prodigious amounts of water to produce them, both to raise the animals […]

Robot finger with human-like skin in collagen Source: Shoji Takeuchi, University of Tokyo

It may sound like science fiction, but it isn’t. Researchers at the University of Tokyo have, for the first time, made “living” skin for robots out of human cells. While this may sound creepy, it is actually a technological advance that will have serious implications for both how robots work and how humans interact with […]

A cancer study sponsored by drug company GlaxoSmithKline has provided researchers with a surprising result: a 100% remission rate for the 12 participants. All of the study’s participants had a very specific type of advanced rectal cancer – mismatch-repair deficient colorectal cancer – that, due to its genetic traits, made it a good candidate for […]

Batteries power our daily lives. From communications and information technology in phones and laptops, to mobility in cars, motorcycles, and scooters, and beyond, most electronic objects have a battery-powered version. While this has many positive impacts, what we do with the batteries in these objects at the end of their lives still needs some work. […]

The news is full of stories about how plastics are further encroaching into even the most remote regions of the Earth, the latest example being the discovery of microplastics in fresh Antarctic snow, probably the result of traveling through the atmosphere. While the news is indeed dire and the need to curb the production and […]

It looks a bit like a beehive, this 3D printed home located in Massa Lombarda, a town in northern Italy near Ravenna. It took a large 3D printer about 200 hours spaced out over a few months to print this 60-square-meter (645-square-foot) house that looks like no other. Certainly it is not the only 3D […]

Ada Lovelace is largely credited with having written the first computer algorithm. She is also recognized as being the first to understand how a mechanical calculator could actually be used for computing, how it “might act upon other things besides number.” Born from the union between poet Lord Byron and mathematician Anne Isabella Milbanke in […]

Antikythera Mechanism

In 1900, a group of sponge divers found the Antikythera wreck off Point Glyphadia on the Greek island of Antikythera. Among the wreckage was the oldest example of an analogue computer – a hand-powered orrery, or mechanical model of our solar system that predicts the positions and motions of the planets and moon, including eclipses. […]

Orthopedic 3D printing

3D printers aren’t just good for printing prototypes or, in extremely large cases, building whole bridges or houses. Because the list of things that can be put into a 3D printer is quite possibly only limited by our imagination, what can be printed with it is equally unlimited. Great advances have been made in 3D […]
