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 ...
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 ...
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.
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.
Scientists investigate how electric current flows in multilayer 2-D materials
First-ever high-resolution images of a molecule as it breaks and reforms chemical bonds
When Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, ...
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.
New high-speed camera system reveals what snow looks like in midair
University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3-D as they fell – and they don't look much like those perfect-but-rare snowflakes ...
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.
Gene activity and transcript patterns visualized for the first time in thousands of single cells
Biologists of the University of Zurich have developed a method to visualize the activity of genes in single cells. The method is so efficient that, for the first time, a thousand genes can be studied in parallel ...
New particle might make quantum condensation at room temperature possible
Researchers from FOM Institute AMOLF, Philips Research, and the Autonomous University of Madrid have identified a new type of particle that might make quantum condensation possible at room temperature. The ...
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.
