Structural insights into inner workings of viral nanomachine

Researchers are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered pa... Read More

New research reveals how bacteria construct tiny flagella ‘nanomachines’ outside the cell

Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this week in the journal Nature, demonstrate how the mechanism is powered by the s... Read More

Epsilon toxin may trigger multiple sclerosis, research finds

Multiple sclerosis (MS), a central nervous system disease that often leads to paralysis and vision problems, affects approximately 2.3 million people worldwide and has no cure. Though no one knows what triggers MS, researchers have long suspected that a combination of genetic and environmental f... Read More

Metagenomic assembly gives hints about aquatic Spartobacteria

It's a question we ask about many recently discovered bacteria: What, exactly, do the Verrucomicrobial do in the environment? Since their discovery, representatives of the phylum Verrucomicrobia have been detected in soil and aquatic environments around the world, but we have very few existing i... Read More

Separating the good from the bad in bacteria

New microfluidic technique quickly distinguishes bacteria within the same strain; could improve monitoring of cystic fibrosis and other diseases. There are good bacteria and there are bad bacteria — and sometimes both coexist within the same species.

Take, for instance, Pseudomonas aeruginos... Read More

Designer 'Swiss-Army-Knife' Molecule Captures RNA from Single Cells in Their Natural Tissue Environment

A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connectio... Read More

Predictive model a step toward using bacteria as a renewable fuel source

A new transcriptomics-based model accurately predicts how much isoprene the bacterium Bacillus subtilis will produce when stressed or nourished. This model marks a step toward understanding how changes in the bacteria's environment affect gene expression and, in turn, isoprene production. Isopre... Read More

Harvard Scientists Identify Microbe that “Eats” Electricity

In a new study, Harvard scientists show that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located deep in soil and sediment while remaining at the surface.

Former Research Students and Their Success Stories, Part I!

As an educator and researcher at a small liberal arts institution, my success is measured (to me) in watching former students from my classroom and laboratory go on to do great things after graduation. Here, I share some great information about (and by) a former student of mine, Franny Gilman, ... Read More

A Bacterial Body Clock: Cryptic Periodic Reversals In Paenibacillus dendritiformis

As humans we live our lives in 24-hour increments—waking, eating, and sleeping at specific times dictated to us not solely by our discerning willpower, but also by the greater underlying persuasion of our circadian rhythm. Based on the earth’s rotation from day into night, we have internalized a... Read More

Yet another avian influenza virus, H10N8, infects humans

To the collection of avian influenza viruses known to sporadically infect humans – H5N1, H7N9, H7N2, H7N3, H7N7, H9N2, and H10N7 – we can now add H10N8, recently found in two individuals in China. Avian influenza virus H10N8 was first detected in tracheal aspirates from a 73 year old woman who w... Read More

Want to Get the Flu? Catching the Influenza Virus Infection On Purpose

Most people try to avoid catching the flu by taking precautions such as washing their hands often, avoiding people who are already sick, or getting a flu shot.
However, scientist are giving volunteers the flu on purpose by squirting the virus up their nose, all in the name of science.
Why woul... Read More

Gut Bacteria in Preemies Altered by Hospital Stay, Study Finds

Gut bacteria in premature infants don't come from their mothers, but from microbes in the neonatal intensive-care unit (NICU), a new study finds. Babies typically get their gut bacteria from their mothers during childbirth. Premature infants, however, receive antibiotics during their first week ... Read More

The day they discovered the AIDS virus

A historical look back at the discovery of the AIDS virus. Margaret Heckler, president Reagan's Health and Human Services Secretary made the announcement to the world. “First, the probable cause of AIDS has been found: a variant of a known human cancer virus. Second, not only has the agent been ... Read More

Microbiome in gut, mouth, and skin of low birth weight infants differentiate over first weeks after birth

Low birth weight infants are host to numerous microorganisms immediately after birth, and the microbiomes of their mouths and gut start out very similar but differentiate significantly by day 15 according to a study in mBio this week. Researchers from Stanford University and the University of Pi... Read More

Key Mechanism Behind Herpes Revealed

Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chance... Read More

Some immune cells defend only one organ

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of de... Read More

Sausages made with baby poo are completely normal and super healthy, say scientists

Researchers say they have discovered way to ferment sausages that could turn the fatty meat product into a health food similar to probiotic yogurts. The secret ingredient? A type of bacteria found in baby faeces.

Bacteria evade detection net

Slothful response from regulators and manufacturers means antibiotic resistance is missed. Bacteria that are resistant to almost all antibiotics are dreaded by physicians and patients alike. Finding such microbes in a hospital is bad enough, but failing to detect them can lead to something much ... Read More

Good C-DIFF Agents May Keep Our Homeland Safe

Rogue agents always add a thrilling plot twist in any spy television show, movie or Tom Clancy novel. The devastating impact these evildoers have on the world increases suspense and concern for the characters -- and bystanders -- who may become victims. Inevitably, it is up to those who strive f...
