Young Meerkats Learn The Emotion Before The Message In Threat Calls:

Past research has shown that animal vocalizations can do the same, but little is known about the development of the features that encode such information.

Skimmed Milk — Straight From The Cow:

Herds of cows producing skimmed milk could soon be roaming our pastures, reports Cath O’Driscoll in Chemistry & Industry, the magazine of the SCI. Scientists in New Zealand have discovered that some cows have genes that give them a natural ability to produce skimmed milk and plan to use this information to breed herds of milkers producing only skimmed milk.

Inner Workings Of The Magnanimous Mind: Why It Feels Good To Be Altruistic:

It’s an enduring mystery that taunts neuroscientists and evolutionary biologists. If the human brain evolved to maximize its owner’s survival, why are we motivated to help others, even when it incurs some personal cost? One pat answer is that when we help someone in need, we expect him to return the favor. But some kinds of altruism aren’t easy to explain away as mere reciprocity. For example, tax incentives aside, donating money to a charitable cause is unlikely to bring the donor any foreseeable return – except perhaps the “joy of giving.” Two new studies shed light on why it feels good to give by examining how and where altruism originates in the brain.
