As people age, muscles naturally lose mass and strength, a condition known as sarcopenia. The decline can make everyday activities harder and increases the risk of falls, disability and early death.

Canadian researchers have developed a beating three-dimensional heart-on-a-chip with real-time cellular sensing, offering a safer and more precise way to test drugs and study heart disease.

Kirstyn Hill has worked as a clinical pediatric and women’s health pharmacist since 2020. She was driven to work with a patient population that is not often able to easily speak up for themselves and ...

Engineers at Washington University in St. Louis have developed a new class of protein-based fibers modeled on the aligned ...

The “atrofish” reveals early triggers of sarcopenia and links muscle loss to nerve degeneration, establishing a platform for comparative research on muscle aging and potential therapies As people age, ...

Ion channels are narrow passageways that play a pivotal role in many biological processes. To model how ions move through ...

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function ...

This important study demonstrates that a peri-nuclear actomyosin network, present in some types of human cells, facilitates kinetochore-spindle attachment of chromosomes in unfavorable locations - ...

People in their 70s and 80s gave testimonials about how they’d been so stiff, their walk a mere shuffle, but after several weeks of doing Essentrics, they began to straighten up. Their posture ...

Staircase potentiation in skeletal muscle depends on an intensification of the twitch “active state” early in the contraction cycle. A working hypothesis of this is proposed.

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...
