If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the... Read More

Mothers give a newborn baby a gift of germs -— germs that help to kick-start the infant’s immune system. But antibiotics, used to fight bacterial infection, may paradoxically interrupt a newborn’s own immune responses. A new animal study by neonatology researchers at The Children's Hospital of P...

New research reveals the complex dynamic between gut bacteria and the immune system that keeps proteins from flagellin—bacterial tails—under control.
In healthy individuals, the only thing that separates the lining of the human gut from the some 100 trillion bacterial cells in the gastrointes... Read More
Lyme disease is a stealthy, often misdiagnosed disease that was only recognized about 40 years ago, but new discoveries of ticks fossilized in amber show that the bacteria which cause it may have been lurking around for 15 million years – long before any humans walked on Earth.
The findings w... Read More
At Arizona State University’s Biodesign Institute, Cheryl Nickerson and her team have been investigating the intriguing effects of spaceflight on microbial pathogens.
In a new paper appearing in the current issue of the journal PLOS ONE, the team reports their recent work examining spacefligh... Read More
A graduate student came to my office recently to say that she was increasingly bothered by anxiety and the ‘terror’ of having to speak at laboratory meetings. She had also learned a month ago that she was expected to lecture to a class organized by her mentor. The thought of having to lecture to... Read More
Researchers at Bigelow Laboratory for Ocean Sciences dug into the last 70 years of peer-reviewed publications about protozoan parasites that infest bivalve mollusks and found that when an organism can be cultured in the laboratory, more papers and greater understanding result. Senior Research S... Read More
