The mystery of human wrinkles: What do the cells say?

A research team consisting of Professor Dong Sung Kim, Professor Anna Lee, and Dr. Jaeseung Youn from the Department of Mechanical Engineering at POSTECH has successfully recreated the structure of wrinkles in biological ...

Do bacteria age?

Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells.

Scientists decipher the energy patterns in our cells

Our cells harness energy for essential functions such as division, wound healing, and our immune response to diseases including cancer. But until now, the mechanics of how that energy affects cell behavior—and how this ...

CRISPR/Cas9 modifies Euglena to create potential biofuel source

News about biofuels sometimes mentions used cooking oil as a feedstock, but if these substances contain animal fat, they can solidify in colder temperatures. This happens because, chemically, the fatty acids of these and ...

How bacteria actively use passive physics to make biofilms

When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. ...
