Researchers have discovered a novel, second mechanism of action by the antiviral drug remdesivir against SARS-CoV-2, according to findings published in the Journal of Biological Chemistry.

Researchers at EPFL have developed an approach to print tiny tissues that look and function almost like their full-sized counterpart. Measuring just a few centimeters across, the mini-tissues could allow scientists to study biological processes—and even test new treatment approaches—in ways that were previously not possible.

R-spondin, which enhances the growth of normal cells in the gut, suppresses the growth of intestinal cancer cells, thus reducing the formation of intestinal tumors, according to a new study.

Using a single-cell RNA sequencing method and genetic tracing, researchers at Karolinska Institutet, the Medical University of Vienna in Austria and Harvard University in the USA have now identified and characterised all cell populations in mouse teeth and in the young growing and adult human teeth.

Part of the secret to human longevity, researchers say, may lie in chemical changes along the DNA within our cells that slowed the rate of human aging in the 7 to 8 million years since our ancestors went their separate ways from chimps.

In a new paper published in the Journal of Research in Science Teaching, researchers took a closer look at a coding camp for middle school girls and found that nuanced interactions between teachers and campers as well as among the girls themselves impacted how girls viewed themselves as coders.

New research by an international team of chemists describes a new type of artificial cell that can communicate with other cells within the body--with potential applications in the field of smart pharmaceuticals.

Researchers from Children’s Hospital of Philadelphia (CHOP) have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition.

A study conducted by researchers at São Paulo State University (UNESP) suggests that irisin, a hormone secreted from muscles in response to exercise, could have a therapeutic effect on COVID-19 patients.

A new study has laid out the steps that connect the neuromuscular disorder spinal muscular atrophy (SMA) to the mutations in the gene SMN1 that cause the condition. The research may explain how the mutations affect motor neurons and points the way to a better understanding of SMA.
