Pigment or bacteria? Researchers re-examine the idea of 'color' in fossil feathers
Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University ...
Pulling polymers leads to new insights into their mechanical behavior
In collaboration with colleagues from Berlin and Madrid, researchers at the Department of Physics at the University of Basel have pulled up isolated molecular chains from a gold surface, using the tip of ...
Worm-like mite species discovered on Ohio State's campus
It looks like a worm and moves like a worm – sort of. But it is a previously unidentified microscopic species of mite that was discovered by a graduate student on The Ohio State University campus.
Penn researchers 'design for failure' with model material
When deciding what materials to use in building something, determining how those materials respond to stress and strain is often the first task. A material's macroscopic, or bulk, properties in this area—whether ...
Nanotracer tester tells about wells
A tabletop device invented at Rice University can tell how efficiently a nanoparticle would travel through a well and may provide a wealth of information for oil and gas producers.
Oldest bit of crust firms up idea of a cool early Earth
With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.
Scientists unlock a 'microbial Pompeii'
An international team of researchers have discovered a 'microbial Pompeii' preserved on the teeth of skeletons around 1,000 years old. The key to the discovery is the dental calculus (plaque) which preserves bacteria and ...
ORNL microscopy system delivers real-time view of battery electrochemistry
Using a new microscopy method, researchers at the Department of Energy's Oak Ridge National Laboratory can image and measure electrochemical processes in batteries in real time and at nanoscale resolution.
A tricked-out point-and-shoot for the search for extraterrestrial life
(Phys.org) —The next time a NASA rover blasts off to explore Mars or some other planet, it might be equipped with a new type of "do-it-all" camera developed by an engineering team at the University of Arizona.

Approach helps identify new biofuel sources that don't require farmland
While the debate over using crops for fuel continues, scientists are now reporting a new, fast approach to develop biofuel in a way that doesn't require removing valuable farmland from the food production ...
Graphene balloon yields unprecedented images of hydrated protein molecules
(Phys.org) —A graphene water balloon may soon open up new vistas for scientists seeking to understand health and disease at the most fundamental level.
Researchers develop first single-molecule LED
The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: a team led by the Institut de Physique et de Chimie des Matériaux de Strasbourg has developed the first ever ...
Wastewater lagoons are potential energy source, researchers say
(Phys.org) —Wastewater treatment lagoons have the potential to serve as a local energy source, according to a Clarkson University doctoral student.
