November 2009 Geology and GSA Today highlights Oct 31, 2009
Strain localization in vesicular magma: Implications for rheology and fragmentation Heather M. N. Wright and Roberto F. Weinberg, School of Geosciences, Building 28, Monash University, Clayton, VIC 3800, Australia ... Highly destructive explosive volcanic eruptions result from the fragmentation of molten rock and magma ... The mechanism of magma break-up/fragmentation is not well understood due to the variable phases that can be present in magma, including melt, crystals, and bubbles; and due to... (EurekAlert!)
Pacific Safety Products Inc. Announces Fourth Quarter and Fiscal 2009 Results Oct 19, 2009
These products include body armour to protect against ballistic, stab and fragmentation threats, ballistic blankets to reduce blast effects, and protective products against chemical and biological hazards. PSP is the largest armour manufacturer in Canada, directly supplying the Canadian Department of Defence, Federal Government Agencies and major Canadian law enforcement organizations.

Invest and set the Foundation to Come out Ahead in the Rebound, Recommends Frost & Sullivan for the Indian Chemicals & Materials Industry Aug 4, 2009
According to Frost & Sullivan, given the degree of fragmentation in many sub sectors in the South Asian and Southeast Asian region, consolidation is inevitable and this trend is here to stay for the long term. Companies will look to consolidation for diverse interests ranging from enhancing product portfolio to global footprint, customer acquisition and economies of scale. (PR Newswire)
Plastic Not-So-Fantastic: How the Versatile Material Harms the Environment and Human Health Jul 3, 2009
One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics, wrote David Barnes, a lead author and researcher for the. The report was published this month in a theme issue of Philosophical Transactions of The Royal Society B, a scientific journal. (Scientific American)
Unlike rubber bands, molecular bonds may not break faster when pulled Jun 18, 2009
The findings also contradict the conventional interpretation of experimental results obtained by other researchers studying the fragmentation rate of certain proteins containing sulfur-sulfur bonds when stretched with a microscopic force probe ... "We believe the acceleration of the fragmentation was caused by a change in the protein's structure as it was stretched, and had little or nothing to do with increased reactivity of a stretched sulfur-sulfur bond." ... "We might be able to design... (EurekAlert!)
Recent developments at Burnham Institute for Medical Research, May 2009 May 13, 2009
Dr. Stuart Lipton and Dr. Adam Godzik found that S-nitrosylation of Drp1 causes excessive mitochondrial fragmentation, energy compromise, and subsequent synaptic damage and neuronal death in Alzheimer's disease. The good news is that this provides a new disease target that could prevent synapse loss and nerve cell death in Alzheimer's disease, constituting a new strategy for counteracting the disease.

Alzheimer's Disease Linked To Mitochondrial Damage Apr 5, 2009
D., director of the Del E. Webb Center for Neuroscience, Aging and Stem Cell Research, showed that S-nitrosylated Drp1 (SNO-Drp1) facilitates mitochondrial fragmentation, damaging regions of nerve cell communication called synapses. Mitochondria are the energy storehouses of the cell, and their compromise by excessive fragmentation causes synaptic injury and eventual nerve cell death ... Drp1 is an enzyme that mediates fission or fragmentation of mitochondria. (Science Daily)
