Researchers unravel secrets of parasites' replication A group of diseases that kill millions of people each year can't be touched by antibiotics, and some treatment is so harsh the patient can't survive it. They're caused by parasites, and for decades researchers have searched for a "magic bullet" to kill them without harming the patient. Now, a team of microbiologists at the University of Massachusetts Amherst has made an advance th

Hormone discovered that preserves insulin production and beta cell function in diabetes Researchers at Duke University Medical Center have found protective, anti-diabetic functions for a hormone that, like insulin, is produced by the islet cells of the pancreas. The new hormone was found to stimulate insulin secretion from rat and human islet cells and protect islet cells in the presence of toxic, cell-killing factors used in the study.

Chemists use nanopores to detect DNA damage Scientists worldwide are racing to sequence DNA – decipher genetic blueprints – faster and cheaper than ever by passing strands of the genetic material through molecule-sized pores. Now, University of Utah scientists have adapted this "nanopore" method to find DNA damage that can lead to mutations and disease.

Living microprocessor tunes in to feedback MicroRNAs (miRNAs) – tiny strands of non-protein-coding RNAs – start off as long strands of precursor miRNAs. These long strands get chopped up by a special kind of machinery, the "Microprocessor" complex, to transform them into their shorter functional form. The resulting miRNAs bind to messenger RNA (mRNAs) molecules, inhibiting their protein production capacity and thus regulating the levels of

An expanded "DNA alphabet" could carry more information than natural DNA, potentially coding for a much wider rang
