For machine tool history junkies (sadly, the machine tool industry in the U.S. is largely history), I found a marvelous set of historical photos of the Mesta Machine Company in Homestead, Pa. Mesta for decades was largest steel making machine tool company in the world and was located next to U.S Steel’s former Homestead, Pa. Works. It was even on Nikita Kruschev’s itinerary in his visit to the U.S in 1959. Sadly, Mesta like the rest of steel industry in Pittsburgh vanished between 1975-90. It’s assets were acquired by WHEMCO in 1983. The hundreds of photos from the first quarter of the 20th century show what a power Mesta and the U.S. were in steeling making and heavy industry (now there’s a term you don’t hear much any more).
The 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
