Researchers develop improved process for large-scale electron microscopy to visualize small structures

How are networks of neurons connected to make functional circuits? This has been a long-standing question in neuroscience. To answer this fundamental question, researchers from Boston Children's Hospital and Harvard Medical School developed a new way to study these circuits and in the process learn more about the connections between them.

Researchers identify a new link between seizures and connexin 36 deficiency

For the brain to learn, retain memories, process sensory information, and coordinate body movements, its groups of nerve cells must generate coordinated electrical signals. Disorder in synchronous firing can impair these processes and, in extreme cases, lead to seizures and epilepsy.

Researchers succeed in mapping the structure of virus that causes diarrhea

Researchers at Umeå University in Sweden have for the first time at the atomic level succeeded in mapping what a virus looks like that causes diarrhea and annually kills about 50,000 children in the world.

MSU researchers show how microbes could soak up toxic pollutants

When Michigan State University's Gemma Reguera first proposed her new research project to the National Science Foundation, one grant reviewer responded that the idea was not "environmentally relevant."

Researchers receive $2.1 million NIH grant to study causes of congenital heart defects

Congenital heart defects are the most common type of birth defect, affecting nearly 1% of births in the United States each year, according to the Centers for Disease Control. Doctors have been unable to lower that number due to a lack of knowledge about their source.

Comprehensive review details the evolution of surgical microscopes

A clear view of anatomical structures is vital for the success of surgery--especially in microsurgery where narrow anatomical cavities or proximity to vulnerable organs and tissues can pose significant risks to patient health.

Brain damage is not caused by direct COVID-19 attack, indicates study

n an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease.

Research shows how colanic acid extends lifespan in C. elegans

Baylor College of Medicine researcher Meng Wang had already shown that bacteria that make a metabolite called colanic acid (CA) could extend the lifespan of worms in her lab by as much as 50%, but her collaboration with Rice University synthetic biologist Jeffrey Tabor is providing tools to answer the bigger question of how the metabolite imparts longer life.
