Drug purification could be controlled with light using technology supported by Princeton's IP Accelerator Fund
A project aimed at controlling pharmaceutical purification with light, led by CBE researchers, has been selected for financial support from Princeton’s Intellectual Property Accelerator Fund.
Bacteria prompt a new look at the dynamics of collective behavior
A study led by Princeton researchers has revealed how bacteria navigate obstacles to ensure cohesive group movement. The finding has implications for understanding the general processes of collective migration, from cancer cells responding to chemical stimulus to wildebeest moving across the savanna.
Humble lizards offer surprising approach to engineering artificial lungs
A new study from Princeton University shows how the brown anole lizard solves one of nature’s most complex problems — breathing — with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the anole lung develops in just a few days into crude lobes covered with bulbous protuberances. These gourd-like structures, while far less refined, allow the lizard to exchange oxygen for waste gases just as human lungs do. And because they grow quickly by leveraging simple mechanical processes, anole lungs provide new inspiration for engineers designing advanced biotechnologies.
