3-D molecular syringes: Scientists solve structure of infection tool used by Yersinia bacterium
Abdominal pain, fever, diarrhoea—these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called inject ...
Coupled particles cross energy wall
For the first time, a new kind of so-called Klein tunnelling-representing the quantum equivalent of crossing an energy wall- has been presented in a model of two interacting particles. This work by Stefano ...
New quantum dot technique combines best of optical and electron microscopy
It's not reruns of "The Jetsons", but researchers working at the National Institute of Standards and Technology have developed a new microscopy technique that uses a process similar to how an old tube television ...
Chemistry researchers closing in on new atomic force microscope
(Phys.org) —A high-power atomic force microscope that could revolutionize the study of materials at high temperatures and pressures is coming into focus in a Wright State University lab.
Graphene quantum dots: The next big small thing
A Rice University laboratory has found a way to turn common carbon fiber into graphene quantum dots, tiny specks of matter with properties expected to prove useful in electronic, optical and biomedical applications.
Carbon under pressure exhibits interesting traits
High pressures and temperatures cause materials to exhibit unusual properties, some of which can be special. Understanding such new properties is important for developing new materials for desired industrial ...
Researchers' new method may sharpen microscopic images
(Phys.org) —UT Dallas researchers are developing a new low-light imaging method that could improve a number of scientific applications, including the microscopic imaging of single molecules in cancer research.
Researchers set record for detecting smallest virus, opening new possibilities for early disease detection
(Phys.org)—Researchers at Polytechnic Institute of New York University (NYU-Poly) have created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution, an advance ...
New microscope captures movements of atoms and molecules
A new microscope invented at Michigan State University allows scientists to zoom in on the movements of atoms and molecules.
From the mouths of molluscs -- ancient snail relative found
Fossils of toothy, slug-like creatures that grazed the sea floor 500 million years ago have shed light on the origins of modern-day snails, shellfish and squid, a study said Wednesday.
Salt causes chalk cliffs to collapse
Salt plays a greater role in undermining chalk cliffs than previously thought, say scientists. Until recently, if a chalk cliff collapsed it was blamed on waves eroding its base, or the chalk weakening as ...
Tiny wires change behavior at nanoscale
Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale.
Novel technique helps with researching atomic structure of complex surfaces
With a novel idea, a lot of work and some of the world's most sophisticated equipment, researchers at McMaster University have developed a new way to study the structures of complex surfaces, opening the door to future discoveries ...
Researchers show how probiotics boost plant immunity
(Phys.org)—With the help of beneficial bacteria, plants can slam the door when disease pathogens come knocking, University of Delaware researchers have discovered.
