A first look at interstitial fluid flow in the brain

05-Jul-2018 - Interstitial fluid transports nutrients and removes waste between the organs and tissues in our body. In the brain, interstitial fluid is thought to be composed of circulating cerebrospinal fluid, cellular waste and blood plasma, and past research has shown a link between interstitial fluid flow ...

New technology allows scientists to watch cancer cells in action at unprecedented resolution

Affinity capture devices provide a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments

03-Feb-2012 - 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 ...

A New Step towards "Computational Experiments"

Scientists develop the most advanced computer model to-date of the scattering of polarized light from chiral molecules

07-Oct-2011 - 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, ...

Remote-control closed system invented for inserting radio-active atoms inside fullerenes

The new material will increase control of radiation therapy

09-Jul-2009 - 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 ...

The Smell of Iron

"Metallic" odor of iron, iron-containing water, and blood derives from the decomposition of skin oil

20-Oct-2006 - 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 ...
