Researchers Develop New Method To Print Tiny, Functional Organs
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.

Your Cells Look Young for Their Age, Compared to a Chimp's
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.

Interaction Is Important for Girls in STEM
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.

How the Loss of a Single Protein Leads to a Relentless Neuromuscular Disease
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.

Could Psoriatic Arthritis Be Activated by the Same Receptor in Different Patients?
A new study has revealed psoriatic arthritis may be activated by the same trigger in different patients. Researchers identified high levels of a specific receptor in immune cells, giving promising evidence of a single cause for the disease.
