Researchers make hardened wooden knives that slice through steak
The sharpest knives available are made of either steel or ceramic, both of which are man-made materials that must be forged in furnaces under extreme temperatures. Now, researchers have developed a potentially more sustainable way to make sharp knives: using hardened wood. The method, presented October 20th in the journal Matter, makes wood 23 times harder, and a knife made from the material is ne

As the fall chill settles in across the U.S., people are getting out their cozy sweaters and electric blankets, or stocking up on handheld heat packets for extra warmth. But sweaters and blankets are bulky, and heat packs only work for a little while. Now, researchers demonstrate a conductive, durable yarn for lightweight wearable heaters that are re-usable and provide constant, portable warmth.

Translated sums of primitive sets
The Erd\H{o}s primitive set conjecture states that the sum $f(A) = \sum_{a\in A}\frac{1}{a\log a}$, ranging over any primitive set $A$ of positive integers, is maximized by the set of prime numbers. Recently Laib, Derbal, and Mechik proved that the translated Erd\H{o}s conjecture for the sum $f(A,h) = \sum_{a\in A}\frac{1}{a(\log a+h)}$ is false starting at $h=81$, by comparison with semiprimes.
