Journal Club: Being less infectious pays off for lung pathogen

The human body is home to millions of commensal microbes, some of which—given the right circumstances—can cause disease. One such microbe, known as nontypeable Haemophilus influenzae (NTHi), infects the lungs of patients with chronic obstructive pulmonary disease (COPD), a condition that … Continue reading

Journal Club: New screening method promises to reveal elusive cellular receptors for a range of pathogens

The surfaces of human cells are chock-full of proteins that help cells communicate with one another. Unfortunately, many viruses coopt these proteins, latching on in order to enter cells. By revealing which proteins are receptors for which viruses, researchers may … Continue reading

Journal Club: Drug-resistant microbes could threaten future global economy, low income countries in particular

Antimicrobial resistance is not only a major public health threat, but also an economic one, according to researchers at The World Bank. Their new study, published in the journal World Development, suggests that an increase in drug-resistant microbes could cause … Continue reading

Journal Club: Mouse microbiome findings offer insights into why a high-fat, low-carb diet helps epileptic children

For nearly a century, doctors have found that a strict high-fat, low-carbohydrate diet can limit seizures in children with epilepsy when medications fail. But exactly how this ketogenic diet works has remained largely a mystery. Now, researchers at the University … Continue reading

Journal Club: In the mouse gut, a bacteria-killing virus evolves to attack a new strain

In scientists’ quest to understand how gut microbes affect human health, bacteria take center stage. But bacteriophages, the viruses that attack the bacteria, are often overlooked, says microbiologist Luisa De Sordi of the Institut Pasteur in France. “We keep an … Continue reading

Journal Club: Twin study elucidates environmental, genetic contributions to mouth microbiome and oral health

Some of the mouth’s microbial communities may promote good health, while others contribute to cavities, gum disease, and possibly even heart disease. Now, scientists are learning more about how genetic and environmental factors influence the mouth’s microbial makeup, and how … Continue reading

Journal Club: Antarctic cyanobacteria show no changes due to warming—yet

Captain Robert Scott’s Antarctic Discovery expedition took place over 100 years ago—and yet its participants recently racked up another contribution to science. Thanks to the samples of bacterial mats they collected from polar ponds—samples that were pressed, dried, and stored … Continue reading

Journal Club: Antibiotics alter the honeybee microbiome and increase bee death

Antibiotics could potentially disrupt the health-promoting microbes that make up the microbiomes in humans and other animals. But pinning down exactly how microbiomes and antibiotics affect human health is complicated by the sheer number of microbes involved. Evolutionary biologist Nancy … Continue reading

Journal Club: Layer-cake chemistry offers up a cheap way to perform chemical tests

Sana Jahanshahi-Anbuhi started her study with a trip to the supermarket to buy Listerine breath strips, the sort that melt on your tongue in seconds. But the chemical engineering postdoc at McMaster University in Hamilton, Canada wasn’t worried about bad … Continue reading

Journal Club: A new strategy for producing polio vaccine without live virus

The poliovirus, which once paralyzed children across the globe, is nearly eradicated in nature. There were just 74 cases of polio reported in 2015, according to the World Health Organization, down from an estimated 350,000 in 1988. Two vaccines contributed … Continue reading
