Lead pollution in the air may have considerably curbed the greenhouse effect in the past. Lead pollution in the air stimulates the formation of ice particles in clouds. Scientist have found that particles containing lead are excellent seeds for the formation of ice crystals in clouds. This not only has a bearing on the formation [...]

A mother who experienced trauma prior to becoming pregnant affects the emotional and social behavior of her offspring, according to a new study. The researchers chose to investigate rats, as social mammals with cerebral activity that is similar in many ways to that of humans.
A new machine makes an animal heart pump much like a live heart after it has been removed from the animal’s body, allowing researchers to expedite the development of new tools and techniques for heart surgery. The machine saves researchers time and money by allowing them to test and refine their technologies in a realistic [...]
Researchers have revealed a unique strategy evolved by sea urchins to keep their digging teeth sharp enough to carve out hiding holes in limestone.

Rare traits persist in a population because predators detect common forms of prey more easily. Researchers have found that birds will target salamanders that look like the majority — even reversing their behavior in response to alterations in the ratio of a distinguishing trait.
Scientists have long known that members of the phenoloxidase family are involved in skin and hair coloring. When they are mutated, they can cause albinism. Produced over abundantly, they are associated with melanoma. Researchers can now explain how hemocyanin is activated — a finding that could lead to a better understanding of both ends of [...]

Researchers report that certain regions of the brain in long-term meditators were larger than non-meditators. Specifically, meditators showed significantly larger volumes of the hippocampus, and within the orbito-frontal cortex, thalamus and inferior temporal gyrus, all regions of the brain known for regulating emotions.
