This Tiny Sensor Spots Salmonella In Minutes, Not Days

A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.

The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More

Predictive model a step toward using bacteria as a renewable fuel source

A new transcriptomics-based model accurately predicts how much isoprene the bacterium Bacillus subtilis will produce when stressed or nourished. This model marks a step toward understanding how changes in the bacteria's environment affect gene expression and, in turn, isoprene production. Isopre... Read More

Vinegar kills tuberculosis and other mycobacteria (press release)

The active ingredient in vinegar, acetic acid, can effectively kill mycobacteria, even highly drug-resistant Mycobacterium tuberculosis, an international team of researchers from Venezuela, France, and the US reports in mBio®, the online open-access journal of the American Society for Microbiolo...

Bird flu experiments pose risk of accidental release

Research in mammals that aims to prevent future influenza pandemics raises ethical, public health concerns. Experiments creating dangerous flu strains that are transmissible between mammals pose too great a risk to human life from potential release, according to an editorial by researchers from...

Parallel ERV-mediated evolution of blue egg color in chickens

The delightful word 'oocyan' refers to the trait of blue-green eggshell color that occurs in native chickens of Chile (Mapuche fowl) and some of their descendants in North America and Europe, as well as certain Asian chicken breeds (e.g. Dongxiang, Lushi).

Oocyan is an autosomal dominant trai... Read More

Calcium makes for an environmentally friendly pickle

George Washington had a collection of 476 kinds of pickles. To prevent scurvy, Christopher Columbus stocked pickles on the Niña, Pinta, and Santa Maria. Julius Caesar, believing pickles to be invigorating, added them to the Roman legions' diet. In 5000 BCE, the Babylonians were known for picklin... Read More

Scientists develop world’s first light-activated antimicrobial surface that also works in the dark

Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for ... Read More

Bacteria and hand washing Pragmatic to school children in rural Nepal

Hand washing is thought to be effective for the prevention of transmission of
Diarrhea pathogens. However it is not conclusive that hand washing with soap is more
Effective at reducing contamination with bacteria associated with diarrhea than using water only. Read More

Key Mechanism Behind Herpes Revealed

Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chance... Read More

Plant biodiversity under threat from general viruses

Introduced generalist plant viruses from other hosts that encounter native plant species for the first time pose a greater threat to plant biodiversity in south-west Australia than introduced specialist viruses, a recent study found.

The researchers compared impacts of six introduced generali... Read More

Designer 'Swiss-Army-Knife' Molecule Captures RNA from Single Cells in Their Natural Tissue Environment

A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connectio... Read More

Reports hit Agriculture Dept. for ‘serious weaknesses’ in food inspection measures

Recent salmonella outbreaks that sickened at least 523 people and sent dozens to the hospital underscore “serious weaknesses” in the U.S. Department of Agriculture’s oversight of poultry plants, according to a study released Thursday by the Pew Charitable Trusts, which also criticized the govern...

New research reveals how bacteria construct tiny flagella ‘nanomachines’ outside the cell

Cambridge scientists have uncovered the mechanism by which bacteria build their surface propellers (flagella) – the long extensions that allow them to swim towards food and away from danger. The results, published this week in the journal Nature, demonstrate how the mechanism is powered by the s... Read More

Scientists: Mosquito Virus Spreads to Americas

A nasty virus first detected in Africa that is spread to people by the bite of infected mosquitoes is being locally transmitted in the Americas for the first time on the tiny French Caribbean dependency of St. Martin, health officials said Tuesday.

Epidemiologists have so far confirmed about ... Read More

Cilia use different motors for different tasks

Cilia — short, hair-like fibers — are widely present in nature. Single-celled paramecia use one set of cilia for locomotion and another set to sweep nutrients into their oral grooves. Researchers at Brown have discovered that those two cilia sets operate at different speeds when the viscosity of... Read More

Oral Bacteria and Cancer

Over a number of years, epidemiological studies established several well-defined risk factors for cancer, including age, heredity, diet, tobacco use, chronic viral infections, and inflammation. Paradoxically, the success of these studies left little room for incorporation of any new factors or c... Read More

Separating the good from the bad in bacteria

New microfluidic technique quickly distinguishes bacteria within the same strain; could improve monitoring of cystic fibrosis and other diseases. There are good bacteria and there are bad bacteria — and sometimes both coexist within the same species.

Take, for instance, Pseudomonas aeruginos... Read More

Neanderthal Me

From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More

New 'gut bacteria' clinical study could help reduce side-effects of radiotherapy

Researchers will examine the role of gut bacteria in influencing the side-effects patients experience after radiotherapy, in the first clinical study of its type.

The study will be carried out by researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Tru... Read More

Blu-ray player detects microorganisms and toxins on discs

In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More
