Stressed rattlesnakes found to calm down in the company of a nearby ‘friend’
In highly social animals, such as mammals and birds, this phenomenon is well studied. Now, researchers have examined social buffering in rattlesnakes and found that the presence of a second snake significantly reduced rattlesnakes' change in heart rates after they experienced disturbance. It is the first evidence of social buffering in reptiles.

Men are hunters, women are gatherers. That was the assumption. A new study upends it.
Their findings — published in the journal PLOS One this week — is that in 79% of the societies for which there is data, women were hunting. [Moreover], this wasn't just opportunistic killing of animals that the women happened upon. The vast majority of the [time] "the hunting was purposeful. Women had their own toolkit. They had favorite weapons. Grandmas were the best hunters of the village."

Pace off: NASA Goddard acoustics chamber and US marine band turn up the volume
The acoustics chamber isn't like a concert hall, despite how its name might sound. Instead, the chamber replicates the harsh sound environment of a rocket launch by blasting sound waves at a spacecraft to make sure it can withstand the journey into orbit.
