Breakthrough: Scientists create world's tiniest organic particles

...molds look something like ice cube trays with tiny cavities in them. After that, we mold the carrier and fragile functional materials into whatever particles we want and gently wash them off the molds with buffer solutions into vials or other containers to concentrate them. Then they can be injected." DeSimo...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

... of the lateral ventricles, which are fluid-filled cavities in both brain hemispheres connected the central canal of the spinal cord. Zhou and his colleagues discovered how PK2 guides the migration of neurons born from neural stem cells from the subventricular zone in the brain's core through mature tissue t...

Friendly bacteria in humans may protect against HIV

...us, commonly found colonizing the oral and vaginal cavities of humans. They do not cause disease. They target HIV because the virus is coated with the sugar mannose, which they use as a food source. "Different bacteria have different sugar preferences," says Tao. "To block HIV, however, we needed to find bac...

Falling ants glide back to trunk to avoid dangers of forest floor

...nd collects mosquito larvae from water-filled tree cavities and also collects adult females who've had a recent meal of blood ?his own. He and Dudley are applying for grants to do a more systematic survey to see how common gliding is among the hundreds of species of canopy ants as well as other insects that ...

Purdue proves concept of using nano-materials for drug discovery

...ls discussed in the research paper are cylindrical cavities that are open at the top and sealed at the bottom with a material called alumina, which contains numerous pores measured in nanometers, or billionths of a meter. Researchers are working to duplicate how cell membranes function on chips in order to t...

U-M scientist to talk about tissue engineering at AAAS

...ave a long tradition of finding ways to fill tooth cavities that will not heal on their own, Krebsbach said, and that has led to research in biomaterials, bone and connective tissue function, and then tissue engineering. At Michigan, tissue engineering collaboration includes dentists, M.D.s and engineers, am...
