Organizing a cell's genetic material from the sidelines

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. One of the biggest challenges in biology is to understand how certain regions of this highly packaged DNA can be ...

Stem cell clues uncovered

Proper tissue function and regeneration is supported by stem cells, which reside in so-called niches. New work from Carnegie's Yixian Zheng and Haiyang Chen identifies an important component for regulating stem cell niches, ...

Surprise role of nuclear structure protein in development

Scientists have long held theories about the importance of proteins called B-type lamins in the process of embryonic stem cells replicating and differentiating into different varieties of cells. New research from a team led ...

Non-polluting membrane for outerwear

As part of his master's project, the chemical engineer Mario Stucki developed a breathable, environmentally friendly membrane for rain jackets. With his colleague Anna Beltzung, he has since founded the spin-off Dimpora to ...

A solution to fracture for durable solar cells

Micro cracks in solar cells are a frequent challenge for manufacturers of solar photovoltaic modules. EU-funded researchers introduced an innovative pre-stressing technique to retard the growth of cracks and make durable ...

Giddy up—help for plump ponies is fast on its way

QUT Professor Martin Sillence, from QUT's School of Earth, Environmental and Biological Sciences, said a new veterinary drug related to one used to treat human metabolic syndrome has been found to prevent laminitis in ponies ...
