Scientists gain fascinating insights into the dynamic ultrastructure of the heart

What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the heart beating – almost at a molecular level.

New scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes

A Mount Sinai-led team has developed a reproducible and scalable method to advance maturation of human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs)-;cells that support heart muscle contraction, generated in the lab from human stem cell lines-;which researchers say will improve approaches for disease modeling, regenerative therapies, and drug testing.

A mitochondrial uncoupler prevents sarcopenic obesity in elderly mice

A recently discovered chemical compound helped elderly mice with obesity lose fat and weight, add muscle and strength, reduce age-related inflammation and increase physical activity, a new study shows.

Mice study sheds light on why tissues often fail to regenerate from muscle-loss injuries

Tissues often fail to regenerate from traumatic muscle-loss injuries such as gunshot wounds and car accidents, and new research in mice from the University of Michigan sheds light on why.

Researchers explore a new procedure to disrupt gene regulation

What role does DNA packing play in regulating gene activity? Fanka Rang and Kim de Luca, researchers from Jop Kind’s (group leader at the Hubrecht Institute and Oncode Investigator) group, created a way to monitor both gene activity and DNA packaging at the same time to address this topic.

Hybrid immunity generates improved cell response to fight SARS-CoV-2 infections

People who were infected with SARS-CoV-2 before being vaccinated generate an immune response more specific to fighting viral infections, and produce a broader antibody response, than do people whose only protection is the vaccine, according to researchers at the University of Washington School of Medicine.

Globins in the body help fight liver disease

Anti-fibrotic therapy is still a medical necessity in the treatment of chronic liver disease in humans. The anti-fibrotic activity of globin family members in hepatic stellate cells (HSCs), the principal cell type involved in liver fibrosis, was reported by a research group led by Professor Norifumi Kawada of Osaka Metropolitan University (OMU).

Cryo-electron microscopes help determine how “911” molecule repairs DNA damage

When something unexpected happens with DNA replication, cells call their own form of 911 to stop the process and rectify the problem.

Biologists show how genes may inhibit the growth of Parkinson’s disease in flies and mice

Parkinson’s disease is a neurodegenerative disease in which a specific type of neuron, the dopaminergic neuron, is destroyed.
