Symbiotic algae that live within reef-forming corals scoop up available nitrogen, store the excess in the form or uric acid crystals, and slowly feed it to the coral as needed, according to a study in mBio this week. Scientists have known for years that these symbiotic microorganisms serve up ni... Read More
Health officials reported four more cases of a dangerous new virus in Saudi Arabia on Tuesday.
Three of the patients diagnosed as having the novel coronavirus, or nCoV, are still being treated, a statement on the Saudi Health Ministry website said. The fourth has been discharged from a hospit... Read More

The World Health Organization says it appears likely that the novel coronavirus (NCoV) can be passed between people in close contact. This comes after the French health ministry confirmed a second man had contracted the virus in a possible case of human-to-human transmission. Two more people in ... Read More
I had a conversation with some colleagues last week about “personalized medicine,” which has been transformed now into the term “precision medicine.” The conversation revolved around what to do about the perceived effects of antibiotic treatment on the microbiota of individuals. How does one tre... Read More

On this Mothers' Day, I reflect on the role my late mother had on my own decision to become a scientist. We all owe are mothers a great deal, and not just for the mitochondria! So hurray for mothers everywhere! Read More
Medical implants like catheters and pacemakers can be a hotspot for bacteria, which grow in hard-to-treat films on the surface of such devices. Scientists and engineers are taking different approaches to changing the surface of implants so bacteria can’t take hold. For example, some groups are d... Read More
Infants' early growth is influenced by the types of bacteria in their digestive system, a new study says.
A variety of bacteria quickly populate the sterile digestive tract of a newborn. Norwegian researchers identified connections between specific types of bacteria and infant growth rates.

A groundbreaking study from a well-renowned team of Danish researchers could bring unprecedented relief for sufferers of chronic back pain.
According to the study, which appeared in the European Spine Journal, as much as 40 percent of chronic lower back pain is caused by bacteria. Treating th... Read More
It's easy to forget just how far medicine has progressed. While we may worry about the spread of infectious diseases like avian flu or meningitis today, those pathogens have nothing on fearsome pandemics in the distant past like the Plague of Justinian, which killed over 100 million people from ...

Scientists at a local laboratory say a new piece of technology there can identify bacteria a day earlier than traditional methods.
"If it's a blood infection or meningitis, getting that identification as fast as we can can mean the difference between life and death," said Karen Calvert, a mic... Read More
Bacteria on a surface wander around and often organize into highly resilient communities known as biofilms. It turns out that they organize in a rich-get-richer pattern similar to the distribution of wealth in the U.S. economy, according to a new study by researchers at University of California,...

Women suffering from recurring urinary tract infections may carry a particularly hearty strain of E. coli bacteria that flourishes in both the gut and the bladder, and can migrate back and forth despite repeated treatments, a small new study finds.
Doctors believe that urinary tract infection... Read More
In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people.
A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically ... Read More
French health officials said Friday they are investigating three suspected cases of a deadly new respiratory virus related to SARS, in people who had close contact in the hospital with France's only confirmed case.
Beatrice Degrugillers, a spokeswoman for the regional health agency in France'... Read More
Amoeba eat bacteria and other human pathogens, engulfing and destroying them – or being destroyed by them, but how these single-cell organisms distinguish and respond successfully to different bacterial classes has been largely unexplained.
In a report in the journal Current Biology, research... Read More
Researchers have found a strain of bacteria that can infect mosquitoes and make them resistant to the malaria parasite. The study, in the journal Science, showed the parasite struggled to survive in infected mosquitoes. Malaria is spread between people by the insects so it is hoped that giving m... Read More
In this blog post, I show how students in my freshman "introduction to cell and molecular biology" course used "creativity"-based approaches to better understand concepts in the course---as they prepare for their upcoming final exam. I believe that this kind of approach truly helps with student... Read More
