Kangaroos have ‘green’ farts
The farts and belches of these animals contain less methane than do those from other big grass grazers. Microbes in their digestive tract appear to explain the ‘roos lower production of this greenhouse gas, a new study finds.

Pythons seem to have an internal compass
The giant, Burmese pythons living in Florida’s Everglades like their adopted home. And new research shows they can find their way back to it if people try to move them somewhere else. Not all snakes will do this.

Quieter vibes for city spiders
How much a web vibrates affects how well a spider senses when that web has captured prey. But webs attached to concrete, plastic and other artificial materials vibrate less than do those built on natural materials, such as twigs or leaves.

Passing diseases from bee to bee
A study finds that the viruses and parasites that plague honeybees can infect bumblebees too, sickening another important pollinator.
