Doctors at Harborview Medical Center in Seattle found that patients given a daily antiseptic wipe down were much less likely to develop a catheter-related bloodstream infe... Read More

Engineered bacteria

Researchers have devised a way to attach sugars to proteins using unique biological and chemical methods. This means that large quantities of different glycoproteins can be generated for various medical and biological studies.

When the intestinal bacterium E. coli and the diarrheal pathogen ... Read More

Large Pockets of Methane May Be Building Under Antarctic Ice

Microbes living under ice sheets in Antarctica and Greenland could be churning out large quantities of the greenhouse gas methane, a new study suggests.

In recent years scientists have learned that liquid water lurks under much of Antarctica’s massive ice sheet, and so, they say, the potentia... Read More

3-D cell culture: Making cells feel right at home

The film "Avatar" isn't the only 3-D blockbuster making a splash this winter. A team of scientists from Houston's Texas Medical Center this week unveiled a new technique for growing 3-D cell cultures, a technological leap from the flat petri dish that could save millions of dollars in drug-testi...

Researchers sampled 50 bib clips from hygiene and dental operatories. One out of five... Read More

New Powerful Microscopy Shows Antimicrobial Proteins Killing Bacteria

US researchers have developed a new powerful microscopy technique and used it to show proteins killing bacteria in real time, thus revealing the deadly workings of antimicrobial peptides (AMPs), naturally occurring proteins that scientists are pursuing as a new approach to treating bacterial inf...
