Major hurdle cleared to diabetes transplants

Researchers at Washington University School of Medicine have identified a way to trigger the reproduction of human insulin-producing beta cells in a laboratory setting, potentially removing a significant obstacle to transplanting these cells as a treatment for patients with type 1 diabetes. This new technique uses a cell conditioning s...

Slow earthquakes: It's all in the rock mechanics

A team of seismologists has discovered that slow earthquakes, which last minutes rather than seconds, are linked to the type of rock in faults. Laboratory experiments using natural samples from Japan found that clay minerals play a key role in this slip behavior, influencing how rocks react to shear.

Managing fibromyalgia: A guide for physicians

Fibromyalgia can be diagnosed by relying on the art of medicine, as physical findings or laboratory tests are often absent. Primary care physicians are best positioned to manage this condition due to its prevalence rate, with a combination of nonpharmacologic and pharmacologic therapies being the most appropriate management strategy.

PLOS ONE study: Droplet Digital™ PCR works for GMO quantification

A PLOS ONE study has confirmed that Droplet Digital PCR (ddPCR) technology is suitable for routine analysis of genetically modified organisms (GMOs) in food, feed, and seeds. The study found that ddPCR is more accurate and reliable than real-time quantitative PCR (qPCR) for quantifying GMOs, especially at low levels.

Researchers explain a key developmental mechanism for the first time in plants

A team of researchers from Cold Spring Harbor Laboratory explains for the first time the operation of a mechanism in plants that controls developmental regulatory genes, including homeobox genes like BREVIPEDICELLUS and KNAT2. In plant stem cells, a polycomb gene-repressing protein complex called PRC2 is recruited to specific sites alo...
