“This is an early but exciting step toward recharging aging tissues using their own biological machinery,” Gaharwar says in ...

When our body fights an infection, the immune system must quickly activate defenses and trigger a beneficial inflammatory response. But it is just as important to resolve that inflammation and return ...

Scientists are learning how to revive faltering human cells by loading them with fresh power plants, effectively repairing and recharging tissues that had started to fail. Instead of editing DNA or ...

Study findings map out a new way in which antiviral signals engage with cellular metabolism to balance defense and repair.

Researchers use nanoflower-enhanced stem cells to supply extra mitochondria to damaged cells, restoring energy production and cell function without genetic modification. (Nanowerk News) Biomedical ...

The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching ...

The chemical composition of cryogenically frozen materials that have remained hydrated is technically challenging to investigate due to the limited radiation resistance of hydrated living cells. This ...

Scientists are supercharging T cells with multipotent stromal cells’ mitochondria to make them more ferocious invaders of the tumor microenvironment. An international collaboration between researchers ...

Organelles perform the fundamental processes that help cells (and hence organs, tissues, and organisms) stay alive and operative. In the past several decades, transmission electron microscopy (TEM) ...
