Toxic mercury, accumulating in the Arctic, springs from a hidden source - Environmental scientists have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean. While the atmospheric source was previously recognized, it now appears that twice as much mercury actually comes from the rivers. The revelation implies that concentrations of the toxin may further increase as climate change continues to modify the region's hydrological cycle and release mercury from warming Arctic soils.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/-blmXi61VZA" height="1" width="1"/...

Songbirds' learning hub in brain offers insight into motor control - To learn its signature melody, the male songbird uses a trial-and-error process to mimic the song of its father, singing the tune over and over again, hundreds of times a day, making subtle changes in the pitch of the notes. To accomplish this feat, the Bengalese finch's brain must receive and process large quantities of information about its performance and use that data to precisely control the complex vocal actions that allow it to modify the pitch and pattern of its song. Now, scientists have shown that a key brain structure acts as a learning hub, receiving information from other regions of the brain and figuring out how to use that information to improve its song, even when it's not directly controlling the action.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/Yl8oWNIGXiE" height="1" width="1"/...

Newfound exoplanet may turn to dust: Planet?s dust cloud may explain strange patterns of light from its star - Researchers have detected a possible planet, some 1,500 light years away, that appears to be evaporating under the blistering heat of its parent star. The scientists infer that a long tail of debris -- much like the tail of a comet -- is following the planet, and that this tail may tell the story of the planet's disintegration. According to the team's calculations, the tiny exoplanet, not much larger than Mercury, will completely disintegrate within 100 million years.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/L__TsbldcS4" height="1" width="1"/...

A crowning success for crayfish - Australian freshwater crayfish have a tooth enamel very similar to humans. Nature sometimes copies its own particularly successful developments. Scientists have now found that the teeth of the Australian freshwater crayfish Cherax quadricarinatus are covered with an enamel amazingly similar to that of vertebrates. Both materials consist of calcium phosphate and are also very alike in terms of their microstructure. This extremely hard substance has apparently developed in freshwater crayfish independently from vertebrates, as it makes the teeth particularly strong.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/txu_hVKzKSc" height="1" width="1"/... Multipotent stromal stem cells from normally discarded human placental tissue demonstrate high therapeutic potential - Placental stem cells with important therapeutic properties can be harvested in large quantities from the fetal side of human term placentas (called the chorion). The chorion is a part of the afterbirth and is normally discarded after delivery, but it contains stem cells of fetal origin that appear to be pluripotent -- i.e., they can differentiate into different types of human cells, such as lung, liver, or brain cells. Since these functional placental stem cells can be isolated from either fresh or frozen term human placentas, this implies that if each individual?s placenta is stored at birth instead of thrown away, these cells can be harvested in the future if therapeutic need arises. This potential represents a major breakthrough in the stem cell field.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/5GflEXByFXk" height="1" width="1"/...
