Researchers are facing increasing demands from colleagues, peers and publishers for process documentation including adequate controls, and for extensive documentation of experimental parameters. Without such consideration, there would be little chance to repeat, or even validate, findings.

For scientists, the field of proteomics has always been a double-edged sword. On one hand, technologies such as 2-dimensional gel electrophoresis (2-DE) capture a vastly improved picture of protein expression in action. But when others try to reproduce the experiment? The findings can suddenly appear blurry.

As San Diego’s ViaCyte was in the midst of launching the first FDA-approved embryonic stem (ES) cell clinical trial for diabetics last week, Boston’s Harvard University reported that cells made from ES cells “cured” diabetic mice.

Lethal fibrosis in lungs of mice with idiopathic pulmonary fibrosis (IPF) can be reversed, say researchers. No drug on the market can do this. But the crew pulled it off, in mice, by temporarily restoring (a mimic of) one of the body’s own anti-fibrosis agents, sharply reduced in IPF: microRNA-29.

A team of engineers has successfully developed a three-dimensional-printed device, which mimics the operation of the liver to remove dangerous toxins from the blood.

An experimental drug saved the lives of 16 of 16 monkeys with the Marburg virus, a killer near-indistinguishable from Ebola, which caused the death of a Ugandan health worker Oct. 6.

Real-time qPCR is one of the most ubiquitous laboratory techniques in modern life sciences, commonly used for gene expression analyses and diagnosing infectious diseases. But despite being more than two decades old, many researchers continue to perform qPCR incorrectly and overlook the important step of primer validation and optimization.

Ten times more stem cells may soon be generated from umbilical cords than ever before, according to a new Science study. The potential advance was made via a little-known pyrimidoindole molecule called UM171.

By adding just three compounds to the Nobel-Prize-winning induced pluripotent stem cell recipe, a research group is reporting a huge 90 to 100 percent stem cell haul in under a week.

One of the most rapidly fast-tracked vaccines in history— an anti-Ebola “ChAd3” vaccine— just started clinical trial in humans, and may be done as soon as November. But a second fast-tracked anti-Ebola vaccine— called an “rVSV” vaccine— is hot on its heels.
