The Register: Paperless office? 2.8 trillion pages printed in 2020, down by 14% or 450 billion sheets . “Around 450 billion fewer pages were printed from home and office devices in 2020 as COVID-19 disrupted the world of work. The direction of travel has been obvious in recent times: people were printing less even before the pandemic took hold, but the decline was sharper last year as volumes plunged 14 per cent on 2019 levels to a total of 2.8 trillion pages, according to IDC.”

ScienceBlog: Your Paper Notebook Could Become Your Next Tablet

ScienceBlog: Your Paper Notebook Could Become Your Next Tablet. “Innovators from Purdue University hope their new technology can help transform paper sheets from a notebook into a music player interface and make food packaging interactive. Purdue engineers developed a simple printing process that renders any paper or cardboard packaging into a keyboard, keypad or other easy-to-use human-machine interfaces. This technology is published in the Aug. 23 edition of Nano Energy.”

Phys .org: The smell of old books could help preserve them

Phys .org: The smell of old books could help preserve them. “Old books give off a complex mélange of odors, ranging from pleasant (almonds, caramel and chocolate) to nasty (formaldehyde, old clothes and trash). Detecting early signs of paper degradation could help guide preservation efforts, but most techniques destroy the very paper historians want to save. Now, researchers reporting in ACS Sensors have developed an electronic nose that can non-destructively sniff out odors emitted by books of different paper compositions, conditions and ages.”

A Database of Paper Airplane Designs

Adafruit pointed me toward a database of paper airplane designs. It looks like there are about 40 designs, from easy to expert. Each one I looked at had extensive folding instructions with pictures, a link to a YouTube video, and downloadable instructions. Now I want to fold airplanes.
