New species in an urban ecosystem (read: solar panel)
A new species of bacteria, one that makes its home on the relatively hot and dry surface of a solar panel, was discovered recently at the Arnold Arboretum, offering a lesson that nature’s reach extends even to the artificial.

The ‘right’ diet
Professor Emily Balskus and her team have identified an entirely new class of enzymes that degrade chemicals essential for neurological health, but also help digest foods like nuts, berries, and tea, releasing nutrients that may impact human health.

Assumptions of how antibiotics work may be incorrect
Researchers have discovered that bacteria respond to antibiotics very differently — exactly opposite, in fact — inside the body than they do on a petri dish.

SLIPS inspires second generation
In a study reported in Nature Biotechnology, a team of Harvard scientists and engineers has developed a new surface coating for medical devices using materials already approved by the Food and Drug Administration (FDA). The researchers noted that the coating repelled blood from more than 20 medically relevant substrates (glass, plastic, and metal) and also…

Cheese-based research
Bauer Fellow Rachel Dutton has identified three general types of microbial communities that live on cheese, opening the door to using each as a “model” community for the study of whether and how various microbes and fungi compete or cooperate as they form communities, as well as what molecules and mechanisms are involved in the…

Sizing up bacteria
A new theoretical framework outlined by a Harvard scientist could help solve the mystery of how bacterial cells coordinate processes that are critical to cellular division, such as DNA replication, and how bacteria know when to divide.

Your gut’s what you eat, too
A new Harvard study shows that, in as little as a day, diet can alter the population of microbes in the gut – particularly those that tolerate bile – as well as the types of genes expressed by gut bacteria.

Programming genetic code can lead to better designer genes
The key to programming bacteria to follow orders has been found in its protein production. Researchers have learned that by using more rare words, or codons, near the start of a gene, they can remove roadblocks to protein production. The knowledge may mean new drugs and biofuels.

When bacteria fight back
After the U.S. Centers for Disease Control and Prevention issued a report on the threat from drug-resistant bacteria, David Hooper, a physician at Massachusetts General Hospital and an authority on the subject, discussed the issues during a question-and-answer session.

When timing is everything
In a new paper, Christopher Marx, associate professor of organismic and evolutionary biology, says that beneficial mutations may occur more often than first thought, but many never emerge as “winners” because they don’t fall within the narrow set of circumstances required for them to dominate a population.

When microbes make the food
A Harvard Summer School class spurs learning through food, by examining how microbes — bacteria and fungi — can help as well as harm when they get into food, doing much of the work preparing cheeses, beer, soy sauce, and even chocolate.

My microbes
A new study reports that the superabundance of microbial life lining our GI tracts has co-evolved with us. These bacteria, which are essential for a healthy immune system, are ultimately our evolutionary partners.
