Strongest contender in decades in fight against breast cancer

For decades, hormonal treatment of breast cancer has been going in one direction -- blocking estrogen. Now a global study has discovered there may be another, less toxic way to defeat the most common form of breast cancer.

Artificial cartilage with the help of 3D printing

Growing cartilage tissue in the lab could help patiens with injuries, but it is very hard to make the tissue grow in exactly the right shape. A new approach could solve this problem: Tiny spherical containers are created with a high-resolution 3D printer. These containers are then filled with cells and assembled into the desired shape. The cells from different containers connect, the container itself is degradable and eventually disappears.

Sister cells uncover pre-existing resistant states in cancer

In many cancers, such as ovarian cancer, each round of chemotherapy kills the majority of cancer cells, while a small population of them survives through treatment. These cells are typically more resistant for the next cycle of therapy and can thus regrow to a deadly, treatment resistant tumor. Researchers wanted to know how this small population of surviving cells differs from the other more sensitive cells already before the treatment. To enable this cellular time travel, they developed ReSisTrace, a methodology that takes advantage of the similarity of sister cells to trace back pre-existing treatment resistance in cancer.

Family caregivers face financial burdens, isolation and limited resources − a social worker explains how to improve quality of life for this growing population

Millions of Americans have become informal family caregivers ^[1]: people who provide family members or friends with unpaid assistance in accomplishing daily tasks such as bathing, eating, transportation and managing medications.
