Penn study provides insight into how cells maintain identity during replication

Prior to cell division, chromosomes are seemingly a jumbled mess. During cell division, parent cell chromosomes and their duplicates sort themselves out by condensing, becoming thousands of times more compact than at any other time.

‘Nanokicking’ technology allows scientists to grow 3D mineralized bone tissue

Researchers from the Universities of Glasgow, Strathclyde, the West of Scotland and Galway have grown three-dimensional samples of mineralized bone from human mesenchymal stem cells for the first time without typical osteoinductive media.

DNA robot sorts molecules without external input

Researchers at the California Institute of Technology have developed an autonomous molecular machine comprising a single strand of DNA that can move around, collect specific molecules and sort them into predefined locations. Furthermore, this nanobot has been designed in such a way that requires no external source of energy or instruction.

Study provides first structural glimpse of circadian clock's molecular machinery

Scientists have long known that circadian clocks- biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle- are present in all forms of life, including animals, plants, fungi and some types of bacteria. However, the molecular mechanisms that "run" these systems remain largely unknown.

Seeing the full picture, real-time analysis of live-cells

Every cell is a miniature factory taking in raw material (extracellular signals) and processing it to produce something (a biological response). But unlike a factory that can be easily tweaked to run at steady-state and look the same from day to day, cells are dynamic.

Study identifies novel source for brain's development

A study conducted by a team of researchers at the New York University has found an unexpected source for the development of the brain. According to the research, which was published in the journal Science, a group of non-neuronal cells called glia, which were previously considered as passive support cells, are important for the development of nerve-cells present in the brain.

Antibiotics may kill bacteria differently in vitro vs in vivo

Understanding exactly how antibiotics work (or don’t work) is crucial for developing alternative treatment strategies, not only to target new “superbugs,” but also to make existing drugs more effective against their targets.

Scientists show how receptors for drugs act inside cells

G protein-coupled receptors are the key target of a large number of drugs. Würzburg scientists have now been able to show more precisely how these receptors act in the cell interior.

Scientists identify novel role for retrotransposons in shaping embryonic chromatin landscape

Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant.

Tiny tears in membranes of bone cells may be key to strong bones

The force gravity and physical activity put on our bones causes tiny tears in the membranes of the tiny cells that enable us to make or break down bone, scientists say.

Study provides better understanding of how estrogen regulates gene expression

Estrogen hormones regulate gene expression. They achieve this by first binding to estrogen receptor in the cell nucleus, which triggers the recruitment of different molecules called coactivators in specific order.

Zika suppresses immune system during pregnancy to harm baby, report researchers

Scientists from the University of Southern California (USC) have discovered that the Zika virus works by suppressing a pregnant woman’s immune system so that the virus can spread and increase the chance of harming an unborn baby.
