Thermographic study of freezing water drops: An insight on Mpemba effect [PDF]

open access: yesRev. Mex. Fis. 7, 050601 (2024)
Despite decades of research, the Mpemba Effect challenges scientists, prompting further investigation and refinement of existing hypotheses. This work uses optical tools such as thermography to analyze and study the Mpemba effect on drops. We analyze times and contact angle changes with temperature with an easily controlled experiment.

Supercooling of Alaskan Beetle Larvae as a Winter Survival Strategy

open access: yesSmall Science, EarlyView.
Dehydrated Alaskan beetle larvae in Fairbanks, Alaska, adhere to the bark of trees that are embedded in ice in their natural winter microhabitat (bottom). This enables their bodies to deeply supercool and avoid freezing, in contrast to their fully hydrated summer form (top).
