A new tool could exponentially expand our understanding of bacteria
How do bacteria — harmless ones living in our bodies, or those that cause disease — organize their activities? A new study, combining powerful genomic-scale microscopy with a technical innovation, captured which genes bacteria turn on in different situations and in different spatial environments. The technology, described January 23 in Science, promises to take the ... Read More about A new tool could exponentially expand our understanding of bacteria
Real-time genomic surveillance of bacteria could improve antibiotic therapy
Antibiotic-resistant bacterial infections are increasingly hard to treat, causing more than a million deaths annually around the world. Hospitalized patients with pneumonia, bloodstream infections, urinary tract infections, or abdominal infections are especially at risk. Like a game of Whac-A-Mole, bacteria can develop antibiotic resistance mutations within days of starting an antibiotic, only to be replaced ...

Shaping our intestinal microbiome: What makes certain microbes more ‘fit’?
We now know the microbes that live in our intestines — often called our microbiome — influence our health in many ways. The balance among competing microbial species is believed to contribute to inflammatory bowel disease (IBD), immune disorders, food allergy, neurodegenerative diseases, cancer, and more. The sugars in our diets, in turn, influence that ... Read More about Shaping our intestinal microbiome: What makes certain microbes more ‘fit’?
Hidden part of flu virus yields hope for better vaccines
The annual effort to create a flu vaccine is like a high-stakes game of Whack-a-mole. Even if public health officials develop a vaccine that offers wide protection, the ever-changing influenza virus pops up again the next year in a new guise, often different enough to thwart the body’s defenses. And while most people recover, influenza ... Read More about Hidden part of flu virus yields hope for better vaccines
