Chamois had pneumonia: Cause of death established

In spring 2010, nearly a third of the chamois living in a region of northern Austria suddenly died of unexplained causes. Concerned hunters and foresters sent the carcasses to the University of Veterinary Medicine, Vienna for analysis. Extensive investigations have now revealed that the animals ... Read More

Video of virus-sized particle trying to enter cell

Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nan... Read More

Changing influenza virus neuraminidase into a receptor binding protein

The hemagglutinin (HA) and neuraminidase (NA) glycoproteins of the influenza virus particle serve distinct functions during infection. The HA binds sialic acid-containing cellular receptors and mediates fusion of the viral and cell membranes, while the NA removes sialic acids from glycoproteins.... Read More

Turkeys inspire smartphone-capable early warning system for toxins

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

New Research Gives Clues of Antibiotic Use and Resistance in U.S. Children's Hospitals

Two studies published in the December issue of Infection Control and Hospital Epidemiology show antibiotic resistance patterns for children have held stable over a seven-year period and surgical patients in U.S. children's hospitals account for 43 percent of all antibiotic use in children's hosp...

Malaria control: The great mosquito hunt

The armed guards at Mali's Bamako Senou International Airport had never seen a German shepherd before. The only dogs they were familiar with were the small, scrappy mixed breeds that are common in West Africa. So when Dana, a wolf-like purebred from California, stepped off a plane and into the a...

Dengue Fever Makes Inroads into the U.S.

The mosquito-borne infection is cropping up in Florida, but mysteriously not in similar regions in the nation.

Most Americans lose little sleep over dengue fever. The mosquito-borne infection is a leading killer in the tropics and subtropics, but it’s been a long-held belief that ubiquitous a... Read More

Native bacteria block Wolbachia from being passed to mosquito progeny

Native bacteria living inside mosquitoes prevent the insects from passing Wolbachia bacteria -- which can make the mosquitoes resistant to the malaria parasite -- to their offspring, according to a team of researchers.

The team found that Asaia, a type of bacteria that occurs naturally in Ano... Read More

Antimicrobial Properties

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...

Plasmas attack bacterial cells on several levels

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

C. difficile Vaccine Proves Safe, 100 Percent Effective In Animal Models

An experimental vaccine protected 100 percent of animal models against the highly infectious and virulent bacterium, Clostridium difficile, which causes an intestinal disease that kills approximately 30,000 Americans annually. The research is published ahead of print in Infection and Immunity.

Salt-Tolerant Bacteria Improve Crop Yields

Uzbek microbiologist Dilfuza Egamberdieva hopes to apply her new agricultural technique soon in Uzbekistan to boost the yield of economically important crops such as wheat, cotton, tomato and cucumber. She presented her work at this year's TWAS General Meeting.

Egamberdieva, group leader at t... Read More

FrameBot: a new tool for those pesky sequencing problems

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

Why Scientists Are Trying Viruses To Beat Back Bacteria

Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.

Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More

Artificial Cells and Salad Dressing

A University of California, Riverside assistant professor of engineering is among a group of researchers that have made important discoveries regarding the behavior of a synthetic molecular oscillator, which could serve as a timekeeping device to control artificial cells. Read More

Penn Research Develops ‘Onion’ Vesicles for Drug Delivery

One of the defining features of cells is their membranes. Each cell’s repository of DNA and protein-making machinery must be kept stable and secure from invaders and toxins. Scientists have attempted to replicate these properties, but, despite decades of research, even the most basic membrane st... Read More

Strict Diet Suspends Development, Doubles Lifespan of Worms

The centuries-long search for the fountain of youth has yielded only a few promising leads, one of which entails an extreme, emaciating diet. A new study of the tiny nematode worm C. elegans begins to explain this marvel of calorie restriction and hints at an easier way to achieve longevity.

Oddly Microbial: Selfish Genes*

Evolution is largely driven by conflict, not collaboration, according to cell evolutionist Harmit Malik at the Fred Hutchinson Cancer Research Center (FHCRC). Mammalian cells are contentious places, he explains, populated by alien and host genomic sequences fighting for dominance. "In the compet... Read More

Scientists think mysterious virus could be a signal of a weak immune system

Genomic analysis of transplant patients finds an opportunistic microorganism whose elevated presence could be used an indicator in treatment.

More than 260,000 Americans are alive today thanks to transplant operations that have replaced their failing kidneys, hearts, lungs or livers with hea... Read More

Microbiology and Peep Science at Easter?

Easter in the United States has become a holiday pretty much about high fructose corn syrup. To that end, here is a description of "Peep Science," using those sugary creatures that inhabit this time of year. In addition is a video that links "Peep Science" and microbiology! Read More
