Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move ...

Modern archeologists, excavating ancient Egyptian tombs, have often found something unexpected amongst the tombs’ artifacts: pots of honey, thousands of years old, and yet still preserved. Through millennia, the archeologists discover, the food remains unspoiled, an unmistakable testament to the... Read More
To enter into symbiosis with nitrogen-fixing bacteria, host plants reprogram their root cells. An LMU team has now identified a calcium-binding protein complex that can be persuaded to spontaneously induce the formation of root nodules.
In almost all ecosystems, plant growth rates are limited... Read More
One of the world's oldest known disinfectants – and favorite salad dressings – may prove even stronger than previously thought.
An international research team has found that vinegar – or, more specifically, the active ingredient in vinegar – can kill mycobacteria, including a highly drug-resi... Read More
While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
Doctors are reporting a second instance of a baby born with AIDS going into remission, or possibly cured, by aggressive treatment after birth. The first case, a child from Mississippi who is now 3 1/2, was reported last April. Doctors revealed the case Wednesday at an AIDS conference in Boston. ... Read More
OpenBiome, a company based in Cambridge, Mass., has opened a facility that collects stool samples from healthy, pre-screened individuals. It then processes those "donations" and readies them for shipment to hospitals, where they are put into the colons of people with the deadly gut infection Cl... Read More
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in... Read More
Serratia marcescens is a bacteria that has earned a bad reputation for infecting people in hospitals. It may deserve an even worse reputation. It might have made people believe, for hundreds of years, that the blood of Christ was miraculously appearing in communion wafers.
Serratia marcescens... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Teaming beneath Sweden's thawing permafrost is a previously undiscovered microbe known as methanongen (Candidatus Methanoflorens Stordalenmirensis). As its name suggests, the microbe does one thing really well: release methane into the atmosphere, presenting a feedback loop of gas production tha... Read More
Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to the mix can make a big difference. Wusirika has also shed light on the biochemical pathways...

Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More
Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are ... Read More
Doctors have used gene therapy to upgrade the immune system of 12 patients with HIV to help shield them from the virus's onslaught. It raises the prospect of patients no longer needing to take daily medication to control their infection. The patients' white blood cells were taken out of the body... Read More
Public health officials issued a warning Thursday that thousands of Bay Area residents were potentially exposed to measles last week when a UC Berkeley student with the virus attended classes in Berkeley and rode on BART.
The student, a Contra Costa County resident whose name was not released... Read More
Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.
This is a key step in understanding how our bodies maintain a close ... Read More
In a first-of-its-kind study for Lyme disease, researchers have used live, disease-free ticks to see if Lyme disease bacteria can be detected in people who continue to experience symptoms such as fatigue or arthritis after completing antibiotic therapy. The technique, called xenodiagnosis, attem... Read More
