As they destroy bacteria very efficiently, plasmas constitute an alternative to chemical disinfectants and potentially to antibiotics, as well. How they achieve this effect has been investigated by biologists, plasma physicists and chemists at the Ruhr-Universität (RUB). Cold atmospheric-pressur... Read More
A Minnesota man who returned from a trip to West Africa has been diagnosed with Lassa fever, a severe and sometimes deadly viral disease rarely seen in the United States, health officials said.
The man, who was hospitalized with fever and confusion on March 31, was confirmed to have Lassa fev... Read More
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
One of the Wellcome Trust’s areas of focus for research funding is combatting infectious disease. We have recently agreed a strategic award of over £7.5 million to continue development of an effective and sustainable approach to reducing the transmission of dengue fever. The research is an inte... Read More
By now, many of us are aware that a considerable portion (45% or more) of the human genome consists of transposable elements. These are mobile genetic sequences, such as Alu repeats and long and short interspersed nuclear elements (LINEs and SINEs). A whopping 18% of this so-called "dark matter ... Read More
Experimenting with mice, infectious disease experts at NYU Langone Medical Center have found that immune system cells uninfected with the bacterium that causes tuberculosis trigger immune system T cells to fight the disease. The findings upend the long-held scientific belief that only cells, kno... Read More
The emergence of antimicrobial resistance, coupled with the availability of fewer antifungal agents with fungicidal actions, prompted this present study to characterize Candida species in our environment and determine the effectiveness of virgin coconut oil as an antifungal agent on these specie...

Researchers at Duke University say they have created a blood test that can determine whether a person's respiratory illness is caused by a bacterial infection or a virus, with over 90 percent accuracy.
What's more, the test only takes about 12 hours to get results. Current methods take severa... Read More
A new test for HPV has been cleared as way to screen for cervical cancer, but doctors are concerned that it doesn't do enough to protect younger women.
By its name alone, the Pap smear sounds like an uncomfortable procedure. Say it aloud: Pap smear. And it’s not too pretty to experience eithe... Read More
Cancer has left its 'footprint' on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses th... Read More
In their paper in mBio this week, Wang et al present FrameBot, a program that combines frameshift correction and nearest-neighbor identification in one Java-based tool. Read More
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.

Parasitic worm genome and biology provides a solid basis for the development of new interventions. Researchers have deduced essential biological and genetic information from the genome sequence of the whipworm, an intestinal parasitic worm that infects hundreds of millions of people in developin...

Some may think of turkeys as good for just lunch meat and holiday meals, but bioengineers at UC Berkeley saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathog... Read More
A team of scientists from Washington State University has discovered how one of the planet’s most deadly known viruses employs burglary-ring-like teamwork to infiltrate the human cell.
Nipah virus is so menacing that the nation’s top infectious disease experts served as consultants in the fil... Read More
From Discover: "Scientists have long known of the important roles played by the microbes on and in our bodies — our microbiomes. These little guys outnumber our own cells 10 to 1, and they help regulate everything from the energy we get out of food to the health of our immune systems. Now, scien... Read More
The Lechuguilla Cave in New Mexico is a network of chambers stretching 1,600 feet underground. The bacteria that grow on the walls of its most remote recesses have been living in complete isolation for more than four million years.
In 2010, Gerry Wright, a microbiologist at McMaster Universit... Read More
The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.
Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging t... Read More
Accelerated progress against the global burden of HIV, malaria, and tuberculosis (TB) has been made since 2000 when governments worldwide adopted Millennium Development Goal 6 to combat HIV/AIDS, malaria, and TB. New estimates from a major new analysis show that worldwide, the number of people l... Read More
By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
