Liquids


Liquids are capable of forming a gas-liquid interface: maintenance of the surface requires adequate pressure in the gas. Adequate in this instance means a gas pressure greater than the vaporisation pressure in the liquid. The gas pressure... Read More

Dual virus-receptor duel

Viruses are obligate intracellular parasites: they must enter a cell to reproduce. To gain access to the cell interior, a virus must first bind to one or more specific receptor molecules on the cell surface. Cell receptors for viruses do not exist only to serve viruses: they also have cellular f... Read More

A Whiff of Taxonomy – Archaeoglobus fulgidus

Pick an archaeon, any archaeon, and you will find it has a story to tell. Not all archaea are exotic but plenty of them are. These stalwarts live in environments we humans call extreme, where they carry out what to us seem extreme types of metabolic conversions. Most have come rather late into o... Read More

Innocence by Viral Tagging - Finalist in Ocean 180 Video Challenge

Viruses are the most abundant biological entities on the planet with approximately 1030 in the world’s oceans at any time. As such, they play a central role in global nutrient cycling. Despite their ecological importance, little is known about how viruses interact with their hosts due to the dif... Read More

How a microscopic team alters the course of carbon in the Atlantic ocean - Finalist in Ocean 180 Video Challenge

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More

Viral genomes in 700 year old caribou scat

Recovering viral genomes from ancient specimens can provide information about viral evolution, but not many old nucleic acids have been identified. A study of 700 year old caribou feces reveals that viruses can be protected for long periods of time – under the right conditions. Read More

Supercomputer Modelling of a Complete Human Viral Pathogen: Poliovirus (Polio virus)

Follow the reconstruction and simulation of poliovirus using the BlueGene/Q supercomputer at the Victorian Life Sciences Computation Initiative. The poliovirus model is being used as a basis for understanding antiviral drugs, virus infection and helps us to learn how to model related viruses suc... Read More

Rapid emergence and antigenic diversification of the norovirus 2012 Sydney variant in Denmark, October to December, 2012

The norovirus (NoV) season in Denmark in late 2012 was characterised by an increase in the number of NoV infections caused mainly by the 2012 Sydney variant, but also by the 2009 New Orleans variant. Analysis of approximately 85% of the capsid gene from 10 Sydney 2012 and 9 New Orleans 2009 isol... Read More

BDP FL maleimide
http://www.lumiprobe.com/p/bodipy-fl-maleimide

BDP FL maleimide is a bright and photostable thiol-reactive dye for protein labeling, an ideal replacement for fluorescein for microscopy. BDP FL is a borondipyrromethene dye which has absorption and fluorescence spectra similar... Read More

How influenza virus infection might lead to gastrointestinal symptoms

Human influenza viruses replicate almost exclusively in the respiratory tract, yet infected individuals may also have gastrointestinal symptoms such as vomiting and diarrhea. In mice, intestinal injury occurs in the absence of viral replication, and is a consequence of viral depletion of the gut... Read More

Reduced glycopeptide and lipopeptide susceptibility in Staphylococcus aureus and the “seesaw effect”: Taking advantage of the back door left open?

Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

Molecular mechanisms of resistance

The abilities of bacterial organisms to utilize the various strategies to resist antimicrobial compounds are all genetically encoded.

Intrinsic resistance is that type of resistance which is naturally coded and expressed by all (or almost all) strains of that particular bacterial species. An... Read More
