Telomere shortening, long thought an unwanted side-effect of aging, actually protects against cancer in humans, a new study indicates.

"...Mtb hijacks the immune response at the very early phase of infection by accessing the bone marrow and manipulating stem cells."

Living human lung air sacs grown in a lab in tiny dishes mimic the real thing. These mini-lungs could accelerate COVID-19 research, scientists report.

New microelectrode-array chips for measuring nerve impulses have way more electrodes than previous systems.

An unexpected discovery could provide stem cells for the creation of placenta tissue. Until now, that hasn't been possible.

Capsules carrying tens of thousands of stem cells sped up healing in rodent hearts damaged by heart attacks, researchers report. Can it work in people?

A new method using stem cells could make for much better bone grafts, researchers report. They could help patients avoid pain or even additional surgery.

A new advance could make it easier to study the placenta, and its role in pregnancy, miscarriage, and preeclampsia, say researchers.

A new method turns stem cells into millions of mature human cells in a shorter time frame. That could pave the way for a range of medical applications.

Proteins called Yamanaka factors returned old human cells to a more youthful vigorous state. The proteins worked in a similar way with aging mouse muscles.
