Too-tight membrane keeps cells from splitting

Cells divide to grow new tissues or patch up damaged ones, but when cell division goes wrong, it can cause more harm than good. To avoid dire consequences, namely disease and unwanted cell death, cells employ a suite of failsafes ...

Researchers find mechanism that regulates telomeres

The tips of chromosomes have structures called telomeres comparable to the plastic cover at the end of shoelaces. They work as a protective cap that prevents genetic material from unfolding and corroding. When telomeres do ...

Turning stem cells into bone with nanoclay-reinforced hydrogel

Assistant Professor Alireza Dolatshahi-Pirouz and colleagues have developed a hydrogel that combines synthetic materials with living cells, and can turn stem cells into bone without adding external growth or differentiation ...

Cell division in plants: How cell walls are assembled

Plant researchers at Martin Luther University Halle-Wittenberg (MLU) are providing new insights into basic cell division in plants. The scientists have succeeded in understanding how pivotal processes are coordinated in properly ...

When a defect might be beneficial

In the quest to design more efficient solar cells and light-emitting diodes (LEDs), a team of engineers has analyzed different types of defects in the semiconductor material that enables such devices to determine if and how ...
