8 unusual uses for probiotics

Most of us are familiar with taking our daily probiotic supplement in the conventional way, either in capsule or powder form. It is however becoming increasingly apparent that people are discovering some weird and wonderful ways to use their probiotics, and here nutritional therapist Jo Saunders... Read More

A bacterium reveals the crucible of its metallurgical activity

An international consortium led by CEA researchers in collaboration with the CNRS, has succeeded in characterizing the structure and function of a protein involved in the production of magnetite nanomagnets in magnetotactic bacteria. This protein, MamP, is crucial to the metallurgical activity o... Read More

Laser tool speeds up detection of Salmonella in food products

Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.

Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More

Biotransformation of Enniatins from Fusarium Fungi in a Food Safety Perspective

Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More

Community-based HIV prevention can boost testing, help reduce new infections

Communities in Africa and Thailand that worked together on HIV-prevention efforts saw not only a rise in HIV screening but a drop in new infections, according to a new study in the peer-reviewed journal The Lancet Global Health.

The U.S. National Institute of Mental Health's Project Accept —... Read More

Who's Protecting Whom From Deadly Toxin?

Questions are swirling around a science journal's decision last year to publish a description of a newly discovered botulinum toxin while omitting key genetic details that researchers would normally disclose. The unusual case highlights important unresolved issues in how to balance scientific op... Read More

How Clean Should We Be?

There's a belief that says exposing people -- especially babies and young children -- to different kinds of germs early in life can keep them from developing illnesses like asthma, allergies, and other diseases that affect the immune system. The theory, called the “hygiene hypothesis,” is that o... Read More

An outbreak of enterovirus 68

During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More

A Bacterial Body Clock: Cryptic Periodic Reversals In Paenibacillus dendritiformis

As humans we live our lives in 24-hour increments—waking, eating, and sleeping at specific times dictated to us not solely by our discerning willpower, but also by the greater underlying persuasion of our circadian rhythm. Based on the earth’s rotation from day into night, we have internalized a... Read More

'Transformer' protein provides new insights into Ebola virus disease

A new study reveals that a protein of the Ebola virus can transform into three distinct shapes, each with a separate function that is critical to the virus's survival. Each shape offers a potential target for developing drugs against Ebola virus disease, a hemorrhagic fever that kills up to 9 ou... 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

Wolbachia Genome Reduction, Phage WO, and Reproductive Parasitism

Abstract:

Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... Read More

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

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

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

Books for the Giving Season: Viral Readings

As the year closes out, we enter into the giving seasons of a variety of traditions. Lurking among the more pleasant types of giving is the 2013 – 2014 flu season, a viral gift that often keeps on giving. To combat this, reminders about the potential dangers of influenza and the importance of va... Read More

ASM GM 2014 - Bacteria in Urine Could Cause Overactive Bladder

Contrary to popular belief, urine is not sterile and the bacteria in it may be associated with overactive bladder (OAB) in some women. Presenters will discuss their research ... Read More

Knowing how bacteria take out trash could lead to new antibiotics

A team of scientists has reconstructed how bacteria tightly control their growth and division, the cell cycle, by destroying specific proteins through regulated protein degradation. All organisms use controlled protein degradation to alter cell behavior in response to changing environment. A pro... Read More

The role of uncertainty in infectious disease modelling

The study found that many models provided only cursory reference to the uncertainties of the information and data, or the parameters used

Research by scientists at the University of Liverpool has found that greater consideration of the limitations and uncertainties in infectious disease model... Read More
