Scientists Are Pitting Bacteria Against Each Other in 3D-Printed Cages

The most important zoos of the future might not house endangered lions or tigers. Instead, they could hold disease-causing bacteria.

Scientists at the University of Texas have begun 3D printing microscopic habitats to study bacterial communities. They say the tiny "cages" are better at repro... Read More

Nanotechnology and Learning to Talk to Bacteria: Reginald C. Farrow, Ph.D. at TEDxNJIT

The most well-known advances in nanotechnology have led to dramatically smaller devices that provide us very fast, compact and "smart" electronics including computers, cellphones, and games. In the process we have transformed the way that we communicate with each other. Along with these advances... Read More

Norovirus Vaccine Reduces Symptoms of Illness by More Than Half

An investigational vaccine appears generally well tolerated and effective against the most common strain of norovirus, reducing the main symptoms of the gastrointestinal (GI) infection, vomiting and/or diarrhea, by 52 percent, suggests research being presented at IDWeek 2013™.

Currently, ther... Read More

Innovative approach could ultimately end deadly disease of sleeping sickness

A tag team of two bacteria, one of them genetically modified, has a good chance to reduce or even eliminate the deadly disease African trypanosomiasis, or sleeping sickness, researchers at Oregon State University conclude in a recent mathematical modeling study.

African trypanosomiasis, cause... Read More

Study Looks at the Changing Bacterial Mix After Menopause

The mix of bacteria in the vagina changes as women go through menopause. And a certain mix is typical after menopause in women who have vulvovaginal atrophy (VVA), a common cause of vaginal dryness and sexual pain, finds a team at Johns Hopkins and the University of Maryland. They suspect these ... Read More

Vaccination Campaign Doubles HBV Mutations

A universal infant vaccination campaign in China has led the Hepatitis B virus (HBV) to more than double its rate of "breakout" mutations. These mutations may enable the virus to elude the vaccine, necessitating new vaccination strategies. Researchers at the Chinese Centers for Disease Control a... Read More

History: Great myths die hard

Finding that part of the story of Louis Pasteur's rabies vaccine is false, Héloïse Dufour and Sean Carroll explore how science fables are born, spread and die.

John Snow's ending of London's 1854 cholera outbreak, Joseph Lister's development of antiseptic surgery, Alexander Fleming's inventio... Read More

Good C-DIFF Agents May Keep Our Homeland Safe

Rogue agents always add a thrilling plot twist in any spy television show, movie or Tom Clancy novel. The devastating impact these evildoers have on the world increases suspense and concern for the characters -- and bystanders -- who may become victims. Inevitably, it is up to those who strive f...

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

New Drug Candidate Found for Fungal Lung Infections

On a molecular level, you have more in common with shower curtain mold or the mushrooms on your pizza than you might think. Humans and fungi share similar proteins, a biological bond that makes curing fungal infections difficult and expensive. Current costs to treat these stubborn infections can... 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

Oral bacteria resulting from poor dental hygiene shows a potential association with Alzheimer’s disease

Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.

“This clearly shows that there is an association between oral bacte... Read More

Stability of MERS Under Different Environmental Conditions (research)

The stability of Middle East respiratory syndrome coronavirus (MERS-CoV) was determined at 20°C – 40% relative humidity (RH); 30°C – 30% RH and 30°C – 80% RH. MERS-CoV was more stable at low temperature/low humidity conditions and could still be recovered after 48 hours. During aerosolisation of... Read More

Notre Dame researchers uncover keys to antibiotic resistance in MRSA (press release)

University of Notre Dame researchers Shahriar Mobashery and Mayland Chang and their collaborators in Spain have published research results this week that show how methicillin-resistant Staphylococcus aureus (MRSA) regulates the critical crosslinking of its cell wall in the face of beta-lactam an...

Fecal transplant pill knocks out recurrent C. diff infection, study shows (Press Release)

SAN FRANCISCO – Swallowing pills containing a concentrate of fecal bacteria successfully stops recurrent bouts of debilitating Clostridium difficile (C. diff) infection by rebalancing the bacteria in the gut, suggests a study being presented at the IDWeek 2013™ meeting today.

Infection from C... Read More

Rutgers Scientists Discover Molecules that Show Promise for New Anti-Flu Medicines

A new way to attack flu viruses is taking shape in laboratories at Rutgers University, where scientists have identified chemical agents that block the virus’s ability to replicate itself in cell culture.

These novel compounds show promise for a new class of antiviral medicines to fight much-f... Read More

Antarctica's extreme salt-loving microbes like to swap DNA

Microbes living in Antarctica's saltiest lake swap huge chunks of genetic material as a means of surviving their harsh environment, a new study finds.

The single-celled organisms, called haloarchaea for their salt-loving ways, are biologically distinct from bacteria, algae and other tiny crea... Read More

Liquid soap in public toilets may be covering you in bacteria

Liquid hand soap in many public toilets is doing the opposite of improving hygiene, CCTV reports.

One sample was found to have 600 times more than the standard amount of bacteria, bringing it up to fast food ice levels of grossness. Experts warned that use of the soap could result in skin irr... Read More
