Team maps targets with hopes of blocking reproduction and rendering infection down for the count In any battle, sizing up one's opponent is a critical first step. For researchers fighting a bacterial infection, that means assessing every nook and cranny of the malicious microorganism and identifying which ones to attack. At the Center for Biological Research of the Spanish Research Council in Madrid, scientists are devising maneuvers they hope will take out bacteria at their molecular knees,...

It may seem intuitive that growth and development somehow go together so that plants and animals end up with the right number of cells in all the right places. But it is only now that scientists at the Duke Institute for Genome Sciences & Policy have gotten some of the first insights into how this critical coordination actually works in a plant. The answer is surprisingly simple. A well-known developmental protein called Short-root has been found to directly control the activity, in both...

How do plants and animals end up with right number of cells in all the right places? For the first time, scientists have gained an insight into how this process is co-ordinated in plants. An international team, including Cardiff University's School of Biosciences and Duke University in the USA, have linked the process of cell division with the way cells acquire their different characteristics. A protein called Short-root, already known to play a part in determining what cells will become, was...

Researchers at Virginia Tech, New York University (NYU), and the University of Milan, Italy, have created a data mining algorithm they call GOALIE that can automatically reveal how biological processes are coordinated in time. Biological processes such as cell division, metabolism, and development must be carefully synchronized for proper cell function. How such events are coordinated in time is a complex problem in the field of systems biology. While researchers can gather temporal data...

A new study reveals how conflict resolution works on the microscopic scale "“ a protein called Flower marks the weaker cells for elimination in favor of their fitter neighbors. The research, published by Cell Press in the June 15th issue of the journal Developmental Cell, furthers our understanding of a developmental process of "cell competition" and may provide some insight into pathological conditions that involve imbalances in cell fitness, such as cancer. During development, a cell...

Nuclear pores are the primary gatekeepers mediating communication between a cell's nucleus and its cytoplasm. Recently these large multiprotein transport channels have also been shown to play an essential role in developmental gene regulation. Despite the critical role in nuclear function, however, nuclear pore complexes remain somewhat shadowy figures, with many details about their formation shrouded in mystery. Now a team of investigators from the Salk Institute for Biological Studies has...

Caltech-led team provides evidence of key roles for cell-cycle length and chromosome duplication without division The sepals of the plant Arabidopsis thaliana"”commonly known as the mouse-eared cress"”are characterized by an outer layer of cells that vary widely in their sizes, and are distributed in equally varied patterns and proportions. Scientists have long wondered how the plant regulates cell division to create these patterns"”in other words, how it decides which and...

Proteins called cohesins ensure that newly copied chromosomes bind together, separate correctly during cell division, and are repaired efficiently after DNA damage. Scientists at the Carnegie Institution have found for the first time that cohesins are needed in different concentrations for their different functions. This discovery helps to explain how certain developmental disorders, such as Cornelia de Lange and Roberts Syndrome arise without affecting cell division essential to development....

The tumor suppressor Retinoblastoma represses DNA replication genes during senescence A frequently mutated gene in human cancers is the reitnoblastoma (RB) gene, which controls a potent tumor suppression pathway. Mutations in the gene disable the vast and intricate RB pathway in virtually all tumor cells, leading to disturbances in a host of cellular functions and ultimately provoking cancer. But which of these functions is crucial for the gene's tumor-suppressing activity has been...

If you can imagine identical twin sisters at rest, their breath drawing them subtly together and apart, who somehow latch onto ropes that pull them to opposite sides of the bed"”you can imagine what happens to a chromosome in the dividing cell. Understanding the forces that drive chromosome segregation "“ a crucial aspect of human development and some diseases, including cancer "“ is the goal of an international group of researchers who collaborate each summer at the MBL. In...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
