Because all animal viruses initiate infection by binding to a receptor on the cell surface, this step has long been considered a prime target for antiviral therapy. Unfortunately, drugs that block virus attachment to cells have never shown much promise. Another approach, which is to ablate the r... Read More
Bacteria encased in ice can be resuscitated after thousands, perhaps even millions of years. How these hardy bugs manage to survive deep freeze is something of a mystery. If nothing else, the low levels of radiation hitting Earth’s surface should cause any ice-bound bacterium’s DNA to break apa... Read More
Spiroplasmas are bacteria in the Class Mollicutes that are frequently associated with insects and/or plants. This confocal laser scanning micrographs show aggregates of symbiotic/ commensal spiroplasma-like organisms (SLOs) in the midgut (mg) and filter chamber (fc) of a leafhopper, Dalbulus mai...

Boy, it's a good time to be a dark chocolate lover.
We've noted before the growing evidence that a daily dose of the bitter bean may help reduce blood pressure. There also seems to be a link between a regular chocolate habit and lower body weight.
Now scientists are offering an explanation... Read More
It’s a jungle in there. In the tightly woven ecosystem of the human gut, trillions of bacteria compete with one another on a daily basis while they sense and react to signals from the immune system, ingested food and other bacteria.
Problems arise when bad gut bugs overtake friendly ones, or... Read More
Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.
The plant's longtime sup... Read More
A new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania has found that the risk of hepatitis C-associated serious liver disease persists in HIV patients otherwise benefitting from antiretroviral therapy (ART) to treat HIV.
It has been suggested that... Read More
A new laser sensor identifies Salmonella bacteria grown from food samples in less than 24 hours, about three times faster than conventional methods.
“BARDOT allows us to detect Salmonella much earlier and more easily than current methods,” says Arun Bhunia, professor of food science at Purdue... Read More
In response to drug-resistant “superbugs” that send millions of people to hospitals around the world, scientists are building tiny, “molecular drill bits” that kill bacteria by bursting through their protective cell walls. They presented some of the latest developments on these drill bits, bette... Read More
Around 1 in 5 of the population were infected in both recent outbreaks of seasonal flu and the 2009 H1N1 influenza pandemic, but just 23% of these infections caused symptoms, and only 17% of people were ill enough to consult their doctor. These findings come from a major new community-based stud... Read More
Amidst the myriad of political mechanisms, resistance is the most known. From grassroots picketing to national boycotts to a mass of millions congregating in a country's capital, the practice of protest is as old as civilization. Venturing into the resistance world brings an entirely unique expe... Read More
I entered the bacterial chromosome field in 2004 as a fresh Ph.D. trained in theoretical physics. Ten years is not long enough for one to gain the depth and breadth of a scientific discipline of long history, certainly not for an early career scientist to write an essay of the status of A Mathem...

Once again, you've dropped your snack. You bend down, snatch it up, and gently blow off any dust—and, you hope, deadly germs. You're about to put it in your mouth because, after all, you've got the "five-second rule" on your side: Food that's been dropped is safe to consume if it's been on the f... Read More

Human mouths contain a balanced mix of microbes which, when disrupted, can lead to oral diseases. A study published on March 13th in PLOS Pathogens compares the bacteria and fungi present in the mouths of healthy individuals with those from patients infected with HIV, and illustrates why oral ca...

Although long recognized as an essential defense against the lung-invading fungus Asperfillus fumigatus, Neutrophils actually require a little help from fellow immune cells, according to a study by Amariliz Rivera, her colleagues at Rutgers New Jersey Medical School and scientists at the Fred Hu...

What effect does the varroa mite, and the viruses it transmits, have on bee colonies? To find out, scientists have developed a new computer model to that simulates a honey bee colony over the course of several years.
Shown in the video on this page, the BEEHAVE model was c0-funded by BBSRC and... Read More
Antibiotic-resistant bacteria are on the rise, making it more and more difficult to treat infections. But research suggests that the best defense against harmful bugs could be a healthy population of “good” gut bacteria. The human relationship with microbial life is complicated. At almost any su...

Imagine going to the doctor with an infection and being sent home with a course of drugs. Unknown to your doctor you actually have two infections. If you take the drugs will the other infection go away by itself? What if you take the drugs and the other infection gets worse? This quandary faces ... Read More
