Germs in Space: Preventing Infection on Long Flights

On a long spaceflight unique conditions including microgravity could give microbes the upper hand, but not if astronauts and their spacecrafts are properly prepared. In a new paper, infectious disease expert Dr. Leonard Mermel brings together a broad base of research to come up with specific recommendations for keeping astronauts safe in deep space.

PROVIDENCE, R.I. [Brown University] — The cabin of a spacecraft halfway to Mars would be the least convenient place — one cannot say “on earth” — for a Salmonella or Pneumococcus outbreak, but a wide-ranging new paper suggests that microgravity and prolonged space flight could give unique advantages to germs. What’s a space agency to do? Brown University and Rhode Island Hospital infectious disease expert Dr. Leonard Mermel offers several ideas.

And no, they are not to add more Vitamin C to the Tang, or to give each crew member a bottle of Purell. It’s a lot more complicated than that. (more…)

Copper Kills Harmful Bacteria, UA Researchers Find

Copper alloys may make more hygienic cooking surfaces than stainless steel, according to a recent study by Sadhana Ravishankar of the UA department of veterinary science and microbiology. Her lab group discovered that copper alloys have antimicrobial effects against the foodborne pathogen Salmonella enterica.

Each year a tiny, rod-shaped species of bacteria with a fondness for proliferating on human food causes numerous cases of food poisoning around the world, sometimes leading to severe illness and even death.

The culprit, Salmonella enterica, is a leading cause of diarrheal illness worldwide, said Sadhana Ravishankar, an assistant professor in the University of Arizona department of veterinary science and microbiology.

But Ravishankar’s lab may have discovered a way to reduce the number of food poisoning cases due to Salmonella and possibly other bacteria: prepare food on surfaces made with materials that contain some amount of the element copper, known as copper alloys. (more…)

Salmonella Stays Deadly With a ‘Beta Version’ of Cell Behavior

COLUMBUS, Ohio Salmonella cells have hijacked the protein-building process to maintain their ability to cause illness, new research suggests.

Scientists say that these bacteria have modified what has long been considered typical cell behavior by using a beta form of an amino acid – as opposed to an alpha form – during the act of making proteins. (more…)

Scientists Unfolding Protein Mystery, Fighting Disease with Windows Azure

*Microsoft has partnered with the University of Washington’s Baker Laboratory to help scientists supercharge the computing power of their protein folding research with Windows Azure. Helping scientists get faster results could mean speeding up cures for Alzheimer’s, cancers, salmonella, and malaria.*

REDMOND, Wash. – June 14, 2011 – Cloud computing is helping biologists uncloud one of nature’s biggest mysteries: proteins.

Microsoft has partnered with the University of Washington’s Baker Laboratory, one of the world’s top computational biology labs, to give scientists access to some high-caliber computing power. That, in turn, helps them explore and understand proteins, which could eventually lead to thwarting everything from Alzheimer’s to Malaria, and from cancer to salmonella. (more…)
