Asteroid impact with Moon would produce visible flash, followed by meteor storms

"On December 22, 2032, a sixty-metre-wide asteroid may strike the Moon. If this happens, it will not only produce a visible flash, easily spotted from Earth, but will likely be followed by periodic meteor storms streaking across our night skies. Known as 2024 YR4, this space rock was discovered in late 2024 and initially caused some alarm, as it had a small chance of hitting Earth. Using observations of the object in the months following its discovery, astronomers narrowed down its potential orbital paths."

Sex changes the brains of male mice

"Sex differences in the structure of the brain are well-documented, hotly debated, and ultimately, kind of fuzzy. In humans, at least, they tend to be subtle with plenty of overlap in the bell curves between the sexes. The same is true for mice, but neurologists recently discovered one area in the little critters' brains that shows a striking difference in males and females."

How to get high on your own dopamine — naturally

"If you've experienced a jolt of excitement when your phone buzzes, a rush from seeing a new parking space open up, or a flutter of hope before good news lands, you've experienced dopamine at work. 'Dopamine is the good feeling that you're about to get a reward,' … Beyond anticipation, dopamine also helps reward us after beneficial behaviors such as eating, connecting with others, or accomplishing goals.

The last yak herder of Ladakh

"High on the wind-swept plains of the Changthang plateau, in Ladakh, along the northern tip of India, the world seems untouched by time. Changthang, Tibetan for 'Northern Plateau,' stretches across Ladakh into western Tibet, a seemingly barren expanse of stone, salt, and sky. It is a high-altitude desert where life has adapted over centuries to harsh winds, scarce water, and extreme cold. Yaks lumber across the dusty mountain earth, their breath rising in clouds. Behind them, Thinlay Nurboo, a yak herder, holds a handmade rope with a small stone tied to its end in his hand. Nurboo throws the stone forward to startle approaching wild animals and keep his yaks safe. For generations, the people of Ladakh have shaped their lives and cultural practices around the mountains, farming barley on limited arable land and managing increasingly scarce glacial water that relies on once-regular snowfalls."
