1/2 How much does thinking cost?
The brain consumes a large part of our energy (20% at rest), but it is actually very little (about 17 watts); it is extremely efficient. The most surprising thing is that cognitive effort only increases it by 5%.

“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.”
Better for the climate, better for health, better for livability and quality of life.
Common sense.
Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

NO, they did not "resurrect" the dire wolf (Aenocyon dirus).
They have only edited 14 genes of the gray wolf to resemble it. Apparently, all the changes are focused on its appearance (color, size and shape of the ears)
It is pure propaganda.

'Light' and 'light' are etymologically unrelated.
'Light' (not heavy) as in 'a light load' stems from a different word than 'light' (bright) as in 'a light room'.
Due to regular sound changes, they happened to converge.
In German, they're still different: 'leicht' vs. 'licht'.
