Programmed Cell Death Explained By Lace Plants
2012-07-25 08:21:31

Programmed cell death (PCD) is a highly regulated process that occurs in all animals and plants as part of normal development and in response to the environment. New research published in BioMed Central's open access journal BMC Plant Biology is the first to document the physiological events in the lace plant (Aponogeton madagascariensis) which occur via PCD to produce the characteristic holes in its leaves. The aquatic lace plant, endemic to Madagascar, uses PCD to generate holes in its...

Melbourne researchers are now simulating in 3D, the motion of the complete human rhinovirus, the most frequent cause of the common cold, on Australia´s fastest supercomputer, paving the way for new drug development. Rhinovirus infection is linked to about 70 per cent of all asthma exacerbations with more than 50 per cent of these patients requiring hospitalization. Furthermore, over 35 per cent of patients with acute chronic obstructive pulmonary disease (COPD) are hospitalized each...

New research identifies special protein that determines what goes where As organisms develop, their internal organs arrange in a consistent asymmetrical pattern--heart and stomach to the left, liver and appendix to the right. But how does this happen? Biologists at Tufts University have produced the first evidence that a class of proteins that make up a cell's skeleton -- tubulin proteins -- drives asymmetrical patterning across a broad spectrum of species, including plants, nematode...

By Keeping Their 'Antennae' Up, Lipid Helps Cells Find Their Way
2012-07-09 15:07:12

A lipid that helps lotion soften the skin also helps cells find and stay in the right location in the body by ensuring they keep their "antennae" up, scientists report. Each cell has an antenna, or cilium, that senses the environment then determines where to go and what to do when it arrives, said Dr. Erhard Bieberich, biochemist at the Medical College of Georgia at Georgia Health Sciences University. "A cell is blind; it does not see, it does not feel; it doesn't know where it is,"...

How Bacteria Sense Salt Stress Discovered
2012-07-09 12:09:57

The scientists' finding is a major breakthrough in understanding decades-old problem of how bacteria detect environmental changes A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biological Sciences (DBS) and the Mechanobiology Institute (MBI) has discovered how bacteria respond to salts in their environment and the ways in which salts can alter the behaviour of specialised salt sensor...

Cell is a peer-reviewed scientific journal founded by Benjamin Lewin in January 1974 with the sponsorship of MIT Press. Lewin bought the rights to the journal in 1986 and published it under his own publishing arm Cell Press. Cell Press was sold to Elsevier in 1999, which currently publishes Cell twice monthly. Cell Press publishes several biomedical journals, including Cell, Neuron, Immunity, Molecular Cell, Developmental Cell, Cancer Cell, Current Biology, Structure, Chemistry &...
