Bioengineers have been steadily advancing toward the goal of building lab-grown organs out of a patient’s own cells, but a few major challenges remain.
Engineering researchers are cited for improving living tissues with three-dimensional printed vascular networks made from sugar.
PHILADELPHIA — Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient’s own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory.
PHILADELPHIA — The journal Science is today publishing a paper revealing that highly pathogenic H5N1 influenza, also known as bird flu, can pass from one ferret to another through the air. Publication of these results has been delayed and debated during the last several months for fear that terrorists or others might use information from the study to “weaponize” the flu virus for intentional harm.
PHILADELPHIA -- Memory devices for computers require a large collection of components that can switch between two states, which represent the 1’s and 0’s of binary language. Engineers hope to make next-generation chips with materials that distinguish between these states by physically rearranging their atoms into different phases.
PHILADELPHIA — The University of Pennsylvania is now accepting applications for its Academic Diversity Postdoctoral Fellowship Program.
The program will award postdoctoral fellowships to scholars and educators from different backgrounds, races and ethnic groups and from other diverse groups whose life experience, research experience and employment background will contribute to Penn’s academic excellence. The deadline for applications is Aug. 1.
