Human Body-on-Chip platform enables in vitro prediction of drug behaviors in humans
Drug development is an extremely arduous and costly process, and failure rates in clinical trials that test new drugs for their safety and efficacy in humans remain very high. According to current estimates, only 13.8% of all tested drugs demonstrate ultimate clinical success and obtain approval by the Food and Drug Administration (FDA).

A single number helps Stanford data scientists find most dangerous cancer cells
Biomedical data scientists at the Stanford University School of Medicine have shown that the number of genes a cell uses to make RNA is a reliable indicator of how developed the cell is, a finding that could make it easier to target cancer-causing genes. Cells that initiate cancer are thought to be stem cells, which are hard-to-find cells that can reproduce themselves and develop, or

Cardiac and visual degeneration arrested by a food supplement
Our genome consists of 20,000 genes, all of which may be capable of triggering disease. It is estimated that there are 7,000 unknown genes that cause recessive genetic diseases resulting from mutations in two copies of a gene that have been inherited from each parent. Researchers at the University of Geneva (UNIGE), Switzerland, have recently identified 45 new genes that cause blindness or cognitive problems.

Dozens of non-oncology drugs can kill cancer cells
Drugs for diabetes, inflammation, alcoholism - and even for treating arthritis in dogs - can also kill cancer cells in the lab, according to a study by scientists at the Broad Institute of MIT and Harvard and Dana-Farber Cancer Institute. The researchers systematically analyzed thousands of already developed drug compounds and found nearly 50 that have previously unrecognized anti-cancer activity.

B cells linked to effective cancer immunotherapy
Cancer patients responded better to immunotherapy and had a better prognosis if their melanoma tumours contained specific clusters of B cells, according to new research from Lund University in Sweden. The study is published in Nature.

Edible 'security tag' to protect drugs from counterfeit
Manufacturing prescription drugs with distinct markings, colors, shapes or packaging isn't enough to protect them from counterfeiting, U.S. Drug Enforcement Administration reports have shown. Purdue University researchers are aiming to stump counterfeiters with an edible "security tag" embedded into medicine.

Women's blood vessels age faster than men's
New research from the Smidt Heart Institute at Cedars-Sinai showed for the first time that women's blood vessels - including both large and small arteries - age at a faster rate than men's. The findings, published Wednesday in the journal JAMA Cardiology, could help to explain why women tend to develop different types of cardiovascular disease and with different timing than men.
