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

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 ...
