Imagine you are an ant. You are close to the ground, have pretty poor eyesight, and can’t see all that far ahead of you. How are you going to find your way back home?

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!

A M7.4 earthquake struck the Philippine subduction zone today, causing damaging shaking across much of Mindanao. Several people have died.

This is the Philippines' second deadly earthquake in two weeks. Are the events related? And how does this quake compare to the nearby M7.6 in 2023?

Grocery shops in many wealthy countries are oversupplied with animal-based foods. They stock far more meat and dairy than we need for human and planetary health.

🔗 www.lumipie.com/data-vis/pla...
Data visualization comparing national food supplies in high-income countries (based on GDP per capita) with planetary health intake targets. Radial charts for 12 countries (including Ireland, Denmark, Switzerland, Luxembourg, United States, Australia, Norway, Qatar, Kuwait, Emirates, Taiwan, and Saudi Arabia) show that supplies of animal-based foods, especially meat and dairy, consistently exceed recommended levels of intake. Bars below each chart compare grams of plant-based, animal-based, and fats & oils in total daily supply per person. Data is from FAOSTAT (2022)
