Oviposited eggs are sensitive to experimental heatwaves
Extreme, variable heatwaves are predicted to increase in frequency under global warming, leading to thermal stress that can be damaging to biodiversity. Recently, it has been shown that exposure to h...

This study argues that if one stops and thinks about the task for a minute, one is more likely to go about and complete it (i.e., cut with procrastination).

PERSPECTIVE | The cyclic metabolic switching theory of intermittent fasting
Mark Mattson
The cyclic metabolic switching theory of intermittent fasting - Nature Metabolism
In this Perspective, Mattson discusses that the beneficial effects of intermittent fasting (IF) are mediated by cyclic metabolic switching between ketogenic (fasting) and non-ketogenic (fed) states and that this explains the added health benefits of IF over caloric restriction and ketogenic diets.

Turns out ants and other insects navigate by a property of light humans can’t even see.

Here’s a video that shows the effect. These are polarization filters taped together. As the direction of the filters aligns with the direction of polarization in the sky, they block more light, hence the darkening of only some filters as they’re rotated.

While ants can’t see details and obstacles very well, for them these polarization patterns on the sky are clear as day, and they can use them to find their way around. So human sailors aren’t the only celestial navigators—ants use cues from the sky to get home too!
