Clinging to crevices, E. coli thrive: Study reveals role of flagellum in helping biofilms colonize rough surfaces
New research from Harvard University helps to explain how waterborne bacteria can colonize rough surfaces—even those that have been designed to resist water.
NASA denies report that Voyager left solar system
The US space agency on Wednesday denied a claim made in a scientific study that its Voyager 1 spacecraft had left the solar system, describing the report as "premature." ...
New spectroscopy method could lead to better optical devices
A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films.
In prehistory, CO2 and warming went in lock-step
Levels of carbon dioxide rose hand-in-hand with warming at the end of the last Ice Age, according to a study Thursday that deals a blow to climate skeptics.
High-speed cameras reveal the complex physics at work as air meets water and glass
When a bubble of air rising through water hits a sheet of glass, it doesn't simply stop—it squishes, rebounds, and rises again, before slowly moving to the barrier. This seemingly simple process actually ...
The birth of a very-high-field superconductor
The strong magnetic fields of an MRI scanner or a particle accelerator are generated efficiently by electromagnets that have superconducting wire in their coils. A group of scientists has discovered how to ...

Nano insights could lead to improved nuclear reactors: Researchers examine self-healing abilities of some materials
(Phys.org)—In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now researchers at the ...
Earth's magnetosphere behaves like a sieve
ESA's quartet of satellites studying Earth's magnetosphere, Cluster, has discovered that our protective magnetic bubble lets the solar wind in under a wider range of conditions than previously believed.
