Creating. Roaming free. (Will you kill me?)
Robots exploring deep bodies of water can only go so far before needing to recharge and upload data. Purdue University engineers have designed a mobile docking station system that would help them go farther. (1) How proud we are when creating something. Especially when creating something autonomous. Something that will roam free and independent. So…

Tractionless movement.
Understanding how cells move autonomously is a fundamental question for both biologists and physicists. Experiments on cell motility are commonly done by looking at the motion of a cell on a glass slide under a microscope. In those conditions, cells are observed to "crawl" on the surface. Crawling is well understood: cells attach themselves to…

The origin of life. Creation through Self.
A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early Earth. However, just because molecules could form doesn't mean that the process was likely. Now, researchers have demonstrated that energetically feasible interactions between just two small molecules -- hydrogen cyanide and…

Chaos… Order… Chaos…
Can chaotic systems also synchronize with each other? Physicists from Bar-Ilan University in Israel, along with colleagues from Spain, India and Italy, analyzed the Rossler system and discovered new phenomena that have been overlooked until now. For the first time the researchers were able to measure the fine grain process that leads from disorder to…

Row by row…
Just as children follow a rule to line up single file after recess, some materials use an underlying rule to assemble on surfaces one row at a time, according to the study done at PNNL, the University of Washington, UCLA, and elsewhere. Nucleation - that first formation step - is pervasive in ordered structures across…
