Hauntingly beautiful melodies aren't the first things that come to mind when looking at the periodic table of the elements. However, using a technique called data sonification, a recent college graduate has converted the visible light given off by the elements into audio, creating unique, complex sounds for each one. Today, the researcher reports the first step toward an interactive, musical periodic table. -

Advice on the best products to use for a certain type of hair is often contradictory, and the results can be highly variable. Now, scientists are bringing order to this chaos by identifying properties such as the number of curls or coils in a given length of hair that could eventually help users pick the perfect product and achieve consistent results. -

Those that land here are called meteorites and can be used to peek back in time, into the far corners of outer space or at the earliest building blocks of life. Today, scientists report some of the most detailed analyses yet of the organic material of two meteorites. They've identified tens of thousands of molecular "puzzle pieces," including a larger amount of oxygen atoms than they had expected. -

In his paper published in the journal International Journal of Astrobiology, he suggests that space dust could be harboring signs of life blasted away from other planets by asteroid strikes. -

A new discovery by researchers at Michigan State University and the Carnegie Institution for Science is changing their understanding of iron toxicity in plants caused by low phosphorus levels. -

Complex processes are required for the sunlight-powered conversion of carbon dioxide and water to energy-rich sugar and oxygen. These processes are driven by two protein complexes, photosystems I and II. In photosystem I, sunlight is used with an efficiency of almost 100%. Here a complex network of 288 chlorophylls plays the decisive role. -
