Scientists have determined that human cells are able to shift important gene products into their own mitochondria, considered the power plants of cells. The finding could eventually lead to therapies for dozens of diseases.

Duke University Medical Center scientists have found a mechanism that allows cells starved of iron to shut down energy-making processes that depend on iron and use a less efficient pathway involving glucose. This metabolic reshuffling mechanism, found in yeast cells, helps explain how humans respond to iron deficiency, and may help with diabetes research as well.

When the first cells developed, how could they bring molecules from the environment into their living interior without the specialized structures found on the modern cell membrane? A research team from Massachusetts General Hospital (MGH) has found that the sort of very simple membrane that may have been present on primitive cells can easily allow small molecules – including the building blocks of RNA and DNA – to pass thorough.

Developing techniques to image the complex biological systems found at the sub-cellular level has traditionally been hampered by divisions between the academic fields of biology and physics. However, a new interdisciplinary zeal has seen a number of exciting advances in super-resolution imaging technologies.

The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society’s open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells.

With improved resolution, tissue-specific molecular markers and precise timing, University of Oregon biologist James A. Weston and colleagues have possibly overturned a long-standing assumption about the origin of embryonic cells that give rise to connective and skeletal tissues that form the base of the skull and facial structures in back-boned creatures from fish to humans.

Replacing one amino acid on the surface of a virus that shepherds corrective genes into cells could be the breakthrough scientists have needed to make gene therapy a more viable option for treating genetic diseases such as hemophilia, University of Florida researchers say.
