Certain bonds connecting biological cells get stronger when they’re tugged. Those bonds are known as catch bonds and they’re formed by common adhesion proteins called cadherins. Using computer simulations based on data from previous experiments, researchers in Iowa have answered the question about how these bonds get stronger under force.

NASA on Wednesday confirmed a bonanza of 715 newly discovered planets outside our solar system. Scientists using the planet-hunting Kepler telescope pushed the number of planets discovered in the galaxy to about 1,700. Twenty years ago, astronomers had not found any planets circling stars other than the ones revolving around our sun.
Scientists at Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them. Quasicrystalline materials may be found close to crystalline phases that contain similar atomic motifs, called crystalline approximants. And just like fishing experts know how to hook a big catch, the scientists used their knowledge to hone in on the right spot for their discovery.
Physicists at the U.S. Dept. of Energy's Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors.
The U.S. Department of Energy (DOE) has launched a research hub that focuses on solutions to the domestic shortages of rare earth metals and other materials critical for U.S. energy security.
Scientists at Ames Laboratory have discovered new ways of using a well-known polymer in organic light-emitting diodes (OLEDs), which could eliminate the need for an increasingly problematic and breakable metal-oxide used in screen displays. The polymer, known as PEDOT:PSS, has been around for about 15 years. However, until recently, the material wasn't sufficiently conductive or transparent enough to be a viable ITO substitute.
The prices for rare earths increased ten-fold between 2009 and 2011, prompting researchers at Ames Laboratory to revisit a rare earth recovery process once employed to make high-strength alloy. Now, they are working to more effectively remove neodymium, a rare earth element, from the mix of other materials in a rare earth magnet.
Glass materials may have a far less randomly arranged structure than formerly thought. Over the years, the ideas of how metallic glasses form have been evolving, from just a random packing, to very small ordered clusters, to realizing that longer range chemical and topological order exists. A team of scientists at the Ames Laboratory has been able to show for the first time there is some organization to these structures.
