Fungi that Kill Flies Show Paradox in Nature
A study describes how some fungi act as pests by attacking living insects, notably Empusa muscae which hurls spores to infect flies. It also notes Cordyceps sinensis used in China as a valued medicine and explains the infection process from spore contact to parasite growth.
Human and Fungus Facts Collapse Time devices in Nature
The piece explains how humans act as natural clocks via subconscious time tracking, likening the digestive system to a mainspring and the stomach to an hour hand. It then surveys fungi that infect insects, detailing Entomophthora and Cordyceps species, their life cycles, effects on caterpillars and flies, and their potential as biological control agents in agriculture.

Solving the Secret of Those Ghostly Noises in the Night
A late night guide notes common nocturnal disturbances and odd sounds. It describes wind, ticking clocks, creaking furniture, rustling paper, and a surprising case where a wedding ring’s contraction caused a faint screech, resolved by placing the ring on a mat.
Berlin’s Waffle Surface Asphalt Paves Nonskid Street
An Anti-Skid Street in Berlin received a waffle surfaced asphalt to prevent skidding. A multi‑roller steam wagon overpassed the hot surface to imprint cross ridges for traction. Tests reportedly show reduced accidents in wet weather on the nonskid pavement.

Missing Link in Aviation Invented by California Youths
Malcolm C. Elrick and Eugene P. Frazer, aged twenty-two and twenty-three, have devised the hourometer a device to record flying time from within the aircraft. Previously ground observers noted time, but the hourometer brings constant pilot access to time data, as shown in the accompanying illustration.

Water wheel power system on dry land demonstration
A dry land water wheel uses hillside stream water piped to a wheel to generate electricity for lighting and small machinery. An airplane instrument acts as a timer using landing gear switches, while two dry cells or the generator supply power. A separate note describes Utrecht’s near sound proof room built as a vacuum chamber within a thermos like wall.
