Ryerson University Physicist Dr. Michael Kolios, his former graduate student Dr. Michael Moore, and collaborator zebrafish model expert Dr. Xiao-Yan Wen developed a new mode of photoacoustic imaging called F-mode. This new mode selectively enhances photoacoustic image features based on the size of the object and the sounds it produces.
Researchers from the George Washington University and the Moscow Institute of Physics and Technology have developed a solution for multiparametric optical mapping of the heart's electrical activity. This technique is a useful tool for enhancing our understanding of the mechanisms behind cardiac arrhythmias. Arrhythmia causes your heart to beat too quickly, too slowly or erratically. Hijacking the heart's vital rhythm and pumping function can have serious consequences like a stroke or cardiac arrest.
Duke University researchers have a new explanation for why those endless days of childhood seemed to last so much longer than they do now -- physics. According to the theory, the apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages.
In the blockbuster 'Terminator' movie franchise, an evil robot morphs into different human forms and objects and oozes through narrow openings, thanks to its 'liquid-metal' composition. Although current robots don't have these capabilities, the technology is getting closer with the development of new liquid metals that can be manipulated in 3D space with magnets. Reported in ACS Applied Materials & Interfaces, the materials could someday find applications in soft robotics.
An international team led by Osaka University researchers has shown how the Salmonella protein RamR senses bile acids present in the gut, leading to the activation of a multidrug efflux system that helps bacterial cells to get rid of toxins. This system helps the bacteria to survive and colonize this habitat despite harsh conditions. These findings could form the basis for new therapeutic approaches aimed at combating bacterial infection.
With the release of youth football-helmet ratings by the Virginia Tech Helmet Lab -- already renowned for their helmet ratings for varsity football and other sports -- consumers can see which helmets best reduce concussion risk.
Labiodental sounds, such as F and V, have been known to be rarely met in hunter-gatherer languages. To understand how this has occurred, the authors undertook a massive statistical inquiry. 2,400 languages were analyzed, and a biomechanical model of mouth and lip movements was created.
The ecological bio-production of xylitol and cellulose nanofibers from material produced by the paper industry has been achieved by a Japanese research team. This discovery could contribute to the development of a greener and more sustainable society. The findings were published on March 4, in Green Chemistry.
An Osaka University professor has demonstrated for the first time the value of linear particle accelerators for the generation of free radicals inside biological samples. This work will have important applications throughout biochemistry, especially for researchers studying antioxidants and photosynthesis.
For molecular motors to be exploited effectively, they need to be able to operate in unison. However, integrating billions of these nanometer-sized motors into a single system, and getting them to operate in unison has proved to be quite a challenge. Organic chemists at the University of Groningen have now succeeded in integrating numerous unidirectional light-driven rotary motors into a metal-organic framework (a solid material with a 3D cage-like structure).
