Neurofeedback can enhance the signal-to-noise ratio in thought, enabling a sharper focus on tasks
The sweep of a needle across the grooves of a worn vinyl record carries distinct sounds: hisses, scratches, even the echo of skips. For many years, though, those yearning to hear Frank Sinatra sing "Fly Me to the Moon" have been able to listen to his light baritone with technical clarity, ...
Affinity capture devices provide a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments
A photograph of a polar bear in captivity, no matter how sharp the resolution, can never reveal as much about behavior as footage of that polar bear in its natural habitat. The behavior of cells and molecules can prove even more elusive. Limitations in biomedical imaging technologies have ...
Scientists develop the most advanced computer model to-date of the scattering of polarized light from chiral molecules
An international research team has described the first calculations of Raman optical activity (ROA) spectra using coupled-cluster theory – one of the most reliable quantum chemical methods available. ROA is a valuable tool for the structural characterization of a wide range of molecules, ...
The new material will increase control of radiation therapy
Virginia Tech chemistry Professor Harry C. Dorn, Emory and Henry College chemistry Professor James Duchamp, and Panos Fatouros, professor and chair of the Division of Radiation Physics and Biology at the Virginia Commonwealth University School of Medicine have co-invented a hands-off process for ...
"Metallic" odor of iron, iron-containing water, and blood derives from the decomposition of skin oil
Where does the strange but typical "metallic" smell come from when we touch iron objects such as tools, utensils, railings, or coins? "The smell of iron upon contact with skin is ironically a type of human body odor," states Dietmar Glindemann. "That we are smelling the metal itself is actually ...
