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

HIV Lessons from the Mississippi Baby

The news in July that HIV had returned in a Mississippi toddler after a two-year treatment-free remission dashed the hopes of clinicians, HIV researchers and the public at large tantalized by the possibility of a cure.

But a new commentary by two leading HIV experts at Johns Hopkins argues th... Read More

2 health care workers exposed to MERS patient had flu-like symptoms

Two health care workers went to the emergency room with flu-like symptoms after coming into contact with a patient confirmed to have Middle East Respiratory Syndrome, or MERS, officials said Tuesday.

The Florida patient represents the second confirmed case of MERS brought into the United Stat... Read More

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

Dandruff-Causing Skin Fungi Discovered Unexpectedly in Deep Sea Vents, Antarctica

Until relatively recently, the fungus Malassezia was thought to have one favorite home: us. As the dominant fungus on human skin and sometimes-cause of dandruff, the yeast Malassezia was thought to live a simple if sometimes irritating domestic existence humbly mooching off the oils we exude.

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.

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

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

On Finding Jewels in the Junk

In prokaryotes, it only takes a small jazz band to get the music grooving: piano and a rhythm section suffice. The promoter region of a gene is a tiny stage on which RNA polymerase (p) and few transcription factors (dr, b) improvise on a tune, i.e. they initiate or skip transcription. By contras... Read More

The Discoverability Challenge – How Can We Make Research Data Easier to Find and Use?

Enhancing the discoverability of public health and epidemiology research data is a key to ensuring that it gets more widely used. This was the topic of a recent workshop hosted by the London School of Hygiene and Tropical Medicine, where researchers and data experts explored the findings of a re... 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

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

World Polio Day

As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... Read More

Ancient buried treasure found in daisy seeds

By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.

Researchers at The University of Western Australia, working with academics from The Universi... Read More

Salmonella Infections Fall, But Foodborne Illness Rates Unchanged

Infection from salmonella bacteria, the most common form of food poisoning in the U.S., declined last year but the overall rate of foodborne illness is holding stubbornly steady despite new measures intended to curb it, according to data released Thursday by the federal Centers for Disease Contr...

Recruiting bacteria to be technology innovation partners

For most people biofilms conjure up images of slippery stones in a streambed and dirty drains. While there are plenty of "bad" biofilms around – they even cause pesky dental plaque and a host of other more serious medical problems – a team at the Wyss Institute for Biologically Inspired Engineer...

ASM GM 2014 - The Potential Role of Gut Microbes in Autism

Most gut bacteria are beneficial, aiding food digestion, producing vitamins, and protecting against harmful bacteria. If left unchecked, however, harmful bacteria can excrete... Read More

How evolutionary principles could help save our world

The age of the Anthropocene--the scientific name given to our current geologic age--is dominated by human impacts on our environment. A warming climate. Increased resistance of pathogens and pests. A swelling population. Coping with these modern global challenges requires application of what one... Read More

Bacteria left a methane mess after spill

Study contradicts notion that microbes consumed most of the gas after 2010 Deepwater Horizon spill.

When the blowout of the Deepwater Horizon oil well sent some 400,000 tonnes of methane into the Gulf of Mexico in April 2010, many scientists and others feared it would linger. So researchers w... Read More
