Why charismatic, introduced species are so difficult to manage

Horses have been integral to human life throughout history, and hold widespread cultural significance. But horses are not native (at least in the modern era) to many of the places where they currently roam.

Ancient rocks provide clues to Earth’s early history

The 2.5 billion-year-old Mt. McRae Shale from Western Australia was analyzed for thallium and molybdenum isotope compositions, revealing a pattern that indicates manganese oxide minerals were being buried over large regions of the ancient sea floor. For this burial to occur, O2 needed to have been present all the way down to the sea floor…

Membraneless protocells could provide clues to formation of early life

Membraneless protocells -- called complex coacervates -- can bring together molecules of RNA allowing the RNAs to perform certain reactions, an important step in the origin of life on Earth. The Image shows droplets of complex coacervates as seen under a microscope. The inset shows RNA molecules (cyan) are highly concentrated inside the droplets compared…

A quantum magnet with a topological twist

Researchers explored a material that has an internal structure, shown in 3D in left panel, that consists of triangles and hexagons arranged in a pattern similar to that of a Japanese kagome basket. Credit: Hasan, et. al, Princeton University Taking their name from an intricate Japanese basket pattern, kagome magnets are thought to have electronic…

Fruit fly wing research reshapes understanding of how organs form

This image shows a developing Drosophila fruit fly wing. The colors are marked clones of cells and the shapes of the clones show how growth is organized during development. Credit: Zhenru Zhou How do fruit flies grow their wings? Rutgers scientists discovered a surprising answer that could one day help diagnose and treat human genetic…

Interactive surfaces enter a whole new dimension of flexibility

(left) System Overview, (right) Example of Displaying the Letter "S." Credit: Osaka University An "interactive surface" refers to an interface whose input and output share a common surface that can be manipulated intuitively with the fingers. However, ordinary multi-touch displays, e.g., liquid crystal displays (LCD), can only provide two-dimensional information, limiting expressions and interactions with…

How Capsella followed its lonely heart

Capsella -- microscope image of gene expression analysis. Credit: Yang Dong The Brassicaceae plant family boasts a stunning diversity of fruit shapes. But even in this cosmopolitan company the heart-shaped seed pods of the Capsella genus stand out. An estimated 8 million years ago Capsella embarked on a different evolutionary pathway from its close relatives…

Anemic galaxy reveals deficiencies in ultra-diffuse galaxy formation theory

DGSAT I (left), an ultra-diffuse galaxy (UDG), is shown next to a normal spiral galaxy (right) for comparison. Both are similar in size, but UDGs like DGSAT I have so few stars, you can see right through them, to the galaxies in the background. Credit: A. ROMANOWSKY/UCO/D.
