Computer model demonstrates how human spleen filters blood

Researchers, led by Carnegie Mellon University President Subra Suresh and MIT Principal Research Scientist Ming Dao, have created a new computer model that shows how tiny slits in the spleen prevent old, diseased or misshapen ...

Molecular beacons shine light on how cells 'crawl'

Adherent cells, the kind that form the architecture of all multi-cellular organisms, are mechanically engineered with precise forces that allow them to move around and stick to things. Proteins called integrin receptors act ...

Scientists engineer bacteria-killing molecules from wasp venom

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom. The team hopes to develop the molecules ...

Microrobots in swarms for medical embolization

Microrobotic agents can form swarms of targeted drug delivery for improved imaging analyses. In a new report now published in Science Advances, Junhui Law and a team of researchers in mechanical and industrial engineering, ...

Scientists out for dinosaur blood

Scientists said Tuesday they have discovered what appear to be red blood cells and collagen fibres in dinosaur bones, a find that may boost prospects of prising organic remains from a much wider range of fossils.
