Honey bees are known for their fascinating social structure. A honey bee colony is in fact a well-organized machine, running on good communication, defense and division of labor. As social insects, honey bees have also been shown the communicate to their fellow foragers, a dance to tell their counterparts where food is located. But listening to other bees isn’t always the name of the game. Sometimes the honeybee just wants to do its own thing.

Even when the sea looks clean, its surface can be flecked with tiny fragments of paint and fiberglass. That's the finding from a study that looked for plastic pollution in the uppermost millimeter of ocean. The microscopic fragments come from the decks and hulls of boats, and they could pose a threat to tiny creatures called zooplankton, which are an important part of the marine food web.
The discovery is "continuing to open our eyes to how many small synthetic particles are in the environment," says Kara Law, an oceanographer who studies plastic pollution at the Sea Education Association in Woods Hole, Massachusetts, and wasn’t involved in the study.

Muchos estudios han demostrado el potencial del cambio climático global para mermar los suministros de alimentos. Pero estos estudios, en su mayor parte, ignoran las interacciones entre el aumento de temperatura y la contaminación del aire, especÃficamente la contaminación por ozono que se sabe que daña los cultivos.
Un nuevo estudio con la participación de investigadores del MIT demuestra que estas interacciones pueden ser muy significativas, lo que sugiere que las...

Many studies have shown that personal care products, like toothpaste, shampoo, and other drugs that we use and get into our wastewater have negatively affected fish populations, disrupting their endocrine systems. But can there be any positive effects? A new study shows that one antianxiety drug that made its way into a lake in Sweden has in fact, positively affected the Eurasian perch population, making them bolder, less social, and more active than unexposed fish, ultimately reducing their mortality rates.
