Biotin supplements caused misleading test results, almost led to unnecessary procedure
A new case report describes how a patient's use of a common over-the-counter biotin supplement caused clinically misleading test results and almost resulted in an unnecessary, invasive medical procedure.

MR spectroscopy imaging reveals effects of targeted treatment of mutant IDH1 gliomas
Using a novel imaging method, a research team is investigating the mechanisms behind a potential targeted treatment for a subtype of the deadly brains tumors called gliomas.

Researchers operate lab-grown heart cells by remote control
Researchers have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command -- simply by shining a light on them and varying its intensity. The cells are grown on a material called graphene, which converts light into electricity, providing a more realistic environment than standard plastic or glass laboratory dishes.

Researchers discover how body temperature wrecks potential dengue, Zika vaccine
A major route toward creating effective vaccines against dengue virus and Zika involves the E protein that covers the surface of each viral particle. But creating such a vaccine has proven difficult for a number of reasons. Now researchers have delineated the details of one major barrier to a promising vaccine. It's something we all have -- a natural body temperature of about 98.6 degrees.

Diamond 'spin-off' tech could lead to low-cost medical imaging and drug discovery tools
An international team has discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets.

Variations in placental microbiota appear related to premature birth
Researchers have found a surplus of pathogenic bacteria in placentas from premature births, supporting the hypothesis that maternal infection may cause preterm birth.

New insights into malaria parasite
Scientists have found that various stages of the development of human malaria parasites, including stages involved in malaria transmission, are linked to epigenetic features and how chromatin -- the complex of DNA and proteins within the nucleus -- is organized and structured in these parasites.

The dark side of our genes -- healthy aging in modern times
Scientists collate the evidence for the mismatch between past evolutionary adaptation and our modern lives. They also ask whether natural selection linked to modernization might reduce globally the burden of some chronic diseases.

Cannabis: It matters how young you start
Researchers find that boys who start smoking pot before 15 are much more likely to have a drug problem at 28 than those who start at 15 or after.
