Dear Vincent,


Sorry I missed your visit to NU- my teaching duties in Evanston prevented it!


Several of my students attended both and had good reports all around. Your work on ISGs sounds like it is coming along well.


I just today l... Read More

ASM Live - Antibiotic Exposure, The Microbiome and Obesity

A number of variables can cause signficant changes in the human microbiome early in life including birth method and antibiotic exposure. Understanding these shifts is important because new research suggests that shifts in the microbiome of infants could make them more prone to gain weight as adu... Read More

One Health: Humans, Animals and the Environment

The health of humans, animals, and the environment are inextricably interconnected. Disruption of the environment often creates new niches for the evolution of infectious diseases, and provides opportunities for the transmission of pathogens to animals or humans. The majority of infectious disea... Read More

Is it Ebolavirus or Ebola virus?

When I drafted my article for TakePart (Don’t Panic – Ebola Isn’t Heading For You), I used the term ‘ebolavirus’ throughout, but the editors changed every instance to ‘Ebola virus’. Understanding which term is correct is far more complicated than you might imagine. Read More

Jelly-belly

I guess it doesn't sting, which is a plus - clearly we need no more stinging/biting/blood-sucking creatures on this earth - but my real wonder is what's next, and why rat heart muscle? Read More

The Microbiology of Speciation

The fields of microbial symbiosis and speciation have achieved astonishing advances during the past two decades, yet symbiosis and speciation are not commonly discussed together and can seem to be odd partners in their capacity to operate synergistically in nature. Indeed, microbial symbiosis is... Read More

New study maps hotspots of human-animal infectious diseases and emerging disease outbreaks

A new global study mapping human-animal diseases like tuberculosis (TB) and Rift Valley fever finds that an "unlucky" 13 zoonoses are responsible for 2.4 billion cases of human illness and 2.2 million deaths per year. The vast majority occur in low- and middle-income countries.

The report, wh... Read More

Microbes Go Rafting on Floating Volcanic Rocks

Volcanoes bring death and destruction, but out of the ashes life soon finds fertile ground. A unique experiment is sifting through floating debris from an ongoing volcanic event to see how microbes move in. The results may help in assessing a recent hypothesis that the first life forms may have ... Read More

Titan's tides reveal hidden ocean that could host life

Alien hunters take note: a global water ocean potentially bigger than all those on Earth combined, is sloshing beneath Titan's icy crust.

Combined with the cocktail of organic chemicals already known to exist on Titan, abundant water could make the moon prime real estate for life – though mor... Read More

Intestinal artillery launches anti-bacterial attack

The epithelial cells that line the intestines fire bacteria-fighting “bullets” into the gut, Vanderbilt University researchers have discovered.

The findings, featured on the cover of the April 10 issue of Current Biology, represent a new mechanism for defending the body against gut microbes.

Meningitis Vaccine Being Developed From Common Cold Virus

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Microbiologist Uses Viruses to Fight Bacteria

After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... Read More

Slow-Motion Microbes Still Living off Dino-era "Lunch Box"

Buried under the seafloor for 86 million years, a bacterial community lives so slowly it's still surviving on a "lunch box" from dinosaur days, a new study says. (See marine-microbe pictures.)

It's been known since the 1990s that microbes can live trapped in ocean sediments for millions of ye... Read More

Engineering Life to Survive on Mars and Aid Human Colonization

With NASA’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.

A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploratio... Read More

Sheets of virus generate electricity when squished

Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.

Piezoelectric materials build up charge whe... Read More

19th Century Shipwreck Beer Could Be Recreated

Beer discovered two years ago onboard a shipwreck from the mid-1800s could possibly be recreated using living bacteria discovered in the brew, Finnish researchers announced last Thursday.

According to Terhi Kinnunen of Reuters, Annika Wilhelmson from VTT Technical Research Centre of Finland s... Read More

In First, Software Emulates Lifespan of Entire Organism

Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.

The scientists and other experts said the work was a giant step toward... Read More
