Another beautiful helix for biology, this time reminiscent of a parking garage

Researchers have refined a new microscopy imaging method to visualize exactly how the endoplasmic reticulum sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage with helical ramps connecting the different levels.

New methods to visualize bacterial cell-to-cell communication

Researchers at the University of Basel have developed a live-cell fluorescent labeling that makes bacterial cell-to-cell communication pathways visible. The communication between bacterial cells is essential in the regulation of processes within bacterial populations, such as biofilm development.

Time to investigate the whole human genome

How to cure malignant brain tumour? Why two cells from the same organism, in spite of having identical gene set up, have different shape and functions? How small variations in human genes determine changes in the way we think, feel and behave? Answers to such questions are sought by scientists from the new Laboratory of Molecular Neurobiology of the Nencki Institute.

Researchers step closer to custom-building new blood vessels

Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say.

Scientists construct visual of intracellular 'zip code' signaling linked to learning, memory

New research provides a rare 'picture' of the activity taking place at the single molecular level: visual evidence of the mechanisms involved when a cell transports mRNA (or messenger RNA) to where a protein is needed to perform a cellular function.

Solving DNA puzzles is overwhelming computer systems, researchers warn

Imagine millions of jigsaw puzzle pieces scattered across a football field, with too few people and too little time available to assemble the picture. Scientists in the new but fast-growing field of computational genomics are facing a similar dilemma.

Key step in molecular 'dance' that duplicates DNA deciphered

Scientists have captured new details of the biochemical interactions necessary for cell division -- molecular images showing how the enzyme that unwinds the DNA double helix gets drawn to and wrapped around its target. The research may suggest ways for stopping cell division when it goes awry.
