Why freeloader baby-eating ants are welcomed to the colony  

It might seem surprising that a colony of ants would tolerate the type of guests that gobble both their grub and their babies. But new research shows there's likely a useful tradeoff to calmly accepting these parasite ants into the fold: They have weaponry that's effective against their host ants and a more menacing intruder ant.

Antibiotic resistance can be caused by small amounts of antibiotics  

Antibiotic-resistant bacteria are a global and growing problem in health care. To be able to prevent further development of resistance developing, it is important to understand where and how antibiotic resistance in bacteria arises. New research shows that low concentrations of antibiotics, too, can cause high antibiotic resistance to develop in bacteria.

How your brain learns to expect mud puddles in the park (and other things)  

Whenever there's a mismatch between what you expect to experience and what you actually experience, the brain has to register the error and update your expectation. These changing expectations are fundamental for making decisions. A new study is the first to show how your midbrain responds to the error, and the orbitofrontal cortex updates the information. That's how you know what to expect tomorrow.

First genetic evidence of ongoing mating between 2 distinct species of guenon monkeys  

A new study of guenon monkeys in Gombe National Park is the first to provide genetic evidence of ongoing mating between two distinct species. These monkeys have successfully been producing hybrid offspring for hundreds maybe even thousands of years. Prior studies have suggested that the different physical characteristics of these monkeys keeps them from interbreeding. So, if their faces don't match, they shouldn't be mating, right? Wrong, according to this latest evidence.

Since 1888, this crab had been considered a unique species until a research team recently described five new ones and a new genus.
