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

In a recent study, researchers manipulated cellular proteins that control genes in aged mice. Experimental results showed their livers were rejuvenated to younger states. This work shows promise as a ...

Senolytics—a class of drugs that reduce chronic inflammation and tissue damage in aging cells—are shown to eliminate 30% to 70% of "zombie" cells in the body. These zombie cells, known as senescent ...

Water makes up around 60% of the human body. More than half of this water sloshes around inside the cells that make up organs and tissues. Much of the remaining water flows in the nooks and crannies ...

Gene expression reveals that different types of human cell can work as a unit. These cellular modules, found in several tissues, change during disease. However, suitable computational methods are ...

A dual-action nanomaterial uses cancer’s own chemistry to destroy tumors while leaving healthy cells unharmed.

Your organs are constantly talking to each other in ways we’re only beginning to understand. Tapping into these communication ...

Scientists discover how yellow fever and encephalitis viruses enter human cells, and block them with decoy molecules.

Dissociating tissues into single cells is a core laboratory technique and vital for widely used applications such as next-generation sequencing or flow cytometry. Scientists who employ tissue ...

Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in ...

These images use color markers—blue for nuclei, red for cell membranes, and green for fluid—to show that spaces between cells shrink as fluid moves out during tissue compression, from left to right ...
