3D printed catalysts and new propellant types are making rockets more environmentally-friendly.

Researchers at the University of Toronto Scarborough transformed used cooking oil from deep fryers at McDonald’s into a biodegradable resin.

Turns out that leftover cooking oil in McDonald’s deep fryers is actually good for 3D printing.

Researchers at the University of Toronto Scarborough were able to turn it into a biodegradable resin, they announced in a press release.

When Mina Jang played the same melodious tune on two different flutes behind a screen, she said the examiners grading her couldn’t tell the difference.

Yet the two instruments were made in dramatically different ways.

One was a handmade version of an original early 18th-century flute crafted in 2001, while the other was made of white plastic and “cloned” using a 3D printer in 2019.

Attorneys general in 20 states and the District of Columbia filed a lawsuit Thursday challenging a federal regulation that could allow blueprints for making guns on 3D printers to be posted on the internet.

New York Attorney General Tish James, who helped lead the coalition of state attorneys general, argued that posting the blueprints would allow anyone to go online and use the downloadable files to create unregistered and untraceable assault-style weapons that could be difficult to detect.

The lawsuit, joined by California, Washington and 17 other states, was filed in U.S. District Court in Seattle. It is likely to reignite a fierce debate over the use of 3D-printed firearms and is the latest in a series of attempts by state law enforcement officials to block the Trump administration from easing the accessibility of the blueprints.

The coffin that holds the mummified body of the ancient Egyptian Nesyamun, who lived around 1100 B.C., expresses the man’s desire for his voice to live on. Now, 3,000 years after his death, that wish has come true. Using a 3D-printed replica of Nesyamun’s vocal tract and an electronic larynx, researchers in the UK have synthesized the dead man’s voice. Listen to it here:

Within the next 10 years, what we eat and how it’s grown will be fundamentally transformed.

And converging exponential technologies—from materials science to AI-driven digital agriculture—are not slowing down. Today’s breakthroughs will soon allow our planet to boost its food production by nearly 70 percent, using a fraction of the real estate and resources, to feed 9 billion by mid-century.

What you consume, how it was grown, and how it will end up in your stomach will all ride the wave of converging exponentials, revolutionizing the most basic of human needs.

3D bio-printed Lung tissue.

Rice University researcher’s bioprinting method could be scaled up to one day construct an entire organ and allow organs to be made using some of a patient’s own cells to prevent organ rejection. Researcher’s long term goals are to bioprint fully functioning organs. Synthetic organs can extend the waiting period of an average 3.6 years for a real organ.
