New research from the University of Copenhagen and Copenhagen University Hospital shows that low blood vitamin D levels increase mortality. The study included 96,000 Danes and was recently published in the distinguished British Medical Journal.

Testing for ovarian cancer or the presence of a particular chemical could be almost as simple as distinguishing an F sharp from a B flat, thanks to a new microscopic acoustic device that has been dramatically improved by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

A couple of years ago a scientist looking at dozens of MRI scans of human brains noticed something surprising. A large, fiber pathway that seemed to be part of the network of connections that process visual information showed up on the scans, but the researcher couldn’t find it mentioned in any of the modern-day anatomy textbooks he had.

We’re entering the era of big neuroscience. In a little over a year, the United States, Europe, Japan and Israel have launched brain research projects with big budgets and bold ambitions. Several other countries are expected to follow suit. But what has propelled neuroscience to the vanguard, and what impact will these initiatives have on the field?

A novel looping mechanism that involves the end caps of DNA may help explain the aging of cells and how they initiate and transmit disease, according to new research from UT Southwestern Medical Center cell biologists.

Induced neural stem cells (iNSCs) created from adult cells hold promise for therapeutic transplantation, but their potential in this capacity has been limited by failed efforts to maintain such cells in the desirable multi-potent NSC state without continuous expression of the transcription factors used initially to reprogram them.
