Gut bacteria may be best defense against nasty germs

Antibiotic-resistant bacteria are on the rise, making it more and more difficult to treat infections. But research suggests that the best defense against harmful bugs could be a healthy population of “good” gut bacteria. The human relationship with microbial life is complicated. At almost any su...

What’s eating you? The first food web inside humans suggests potential new treatments for infection

Imagine going to the doctor with an infection and being sent home with a course of drugs. Unknown to your doctor you actually have two infections. If you take the drugs will the other infection go away by itself? What if you take the drugs and the other infection gets worse? This quandary faces ... Read More

A New Future for Anti-viral Therapy

Extramural basic research at the Mount Sinai School of Medicine, funded by the U.S. Army Research Laboratory – Army Research Office (ARL-ARO), has led to discoveries of the biochemical mechanisms for viral growth and of an unprecedented method that may inhibit viral replication. These fundamenta... Read More

Commonly used pain relievers have added benefit of fighting bacterial infection

Some commonly used drugs that combat aches and pains, fever, and inflammation are also thought to have the ability to kill bacteria. New research reveals that these drugs, better known as nonsteroidal anti-inflammatory drugs, act on bacteria in a way that is fundamentally different from current ... Read More

Molecule Plays Important Role in Triggering Immune Response

The nucleoside adenosine—a tiny chemical structure made up of a simple base linked to a sugar—is critical for the regulation of bodily functions ranging from blood flow to tissue repair to sleep. Now, researchers at Rutgers New Jersey Medical School show that adenosine is essential in promoti... Read More

Battling Infection With Microbes

The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, Caltech professor of biology and biological engineering Sa... Read More

Bacterium and Fungus Team Up to Cause Virulent Tooth Decay in Toddlers

Early childhood caries, a highly aggressive and painful form of tooth decay that frequently occurs in preschool children, especially from backgrounds of poverty, may result from a nefarious partnership between a bacterium and a fungus, according to a paper published ahead of print in the journal...

How a Common Fungus Is Protecting the Earth from a Climate Change Nightmare

There is more carbon dioxide stored in the ground than in the air around us. If those all that greenhouse gas escapes, it could be catastrophic for the earth. Now, a researcher at the University of Texas at Austin thinks he’s found the key that keeps much of it locked away. It’s research that co... Read More

Mix Of Gut Microbes May Play Role In Crohn's Disease

More than a million Americans suffer from Crohn's, which seems to start when an overreactive immune system causes abdominal pain, diarrhea, bleeding, weight loss and other symptoms. Many patients have to take powerful steroids (which can have serious side effects), and some have parts of the dig... Read More

Attenuated influenza vaccine enhances bacterial colonization of mice

Infection with influenza virus is known to increase susceptibility to bacterial infections of the respiratory tract. In a mouse model of influenza, increased bacterial colonization was also observed after administration of an infectious, attenuated influenza virus vaccine. Primary influenza viru... Read More

Breathing New Life into DNA Microarrays

DNA microarrays are widely used in biological research and were once thought to be a very promising gene discovery tool. However, since the advent of next generation DNA sequencing, the popularity of DNA microarrays has steadily declined. Compared to the sequencing, microarray behavior is unce... Read More

Feeding the gut microbiota: nutrition and probiotics are key factors for digestive health

A healthy and balanced diet, as well as probiotics, have been known to be helpful in preserving gastrointestinal health for quite a long time. But it is only recently that the underlying mechanisms have become somewhat clearer. A rapidly increasing body of knowledge promises to further clarify t... Read More

A tricky balancing act: antibiotics versus the gut microbiota

Antibiotics are valuable, potentially life-saving tools that have significantly reduced human morbidity and mortality. Unfortunately, antibiotics may also have unintended consequences from their off-target effects that may increase the risk of many long-term conditions. Recent epidemiologic stud... Read More

More than just bacteria: the importance of microbial diversity in gut health and disease

The gut microbiota contains a vast number of microorganisms from all three domains of life, including bacteria, archaea and fungi, as well as viruses. These interact in a complex way to contribute towards both health and the development of disease — interactions that are only now being elucidate... Read More

Harvard Scientists Identify Microbe that “Eats” Electricity

In a new study, Harvard scientists show that the bacterium Rhodopseudomonas palustris can use natural conductivity to pull electrons from minerals located deep in soil and sediment while remaining at the surface.

Researchers prove the five second rule is real

Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University’s School of Life and Health Sciences. The findings suggest there may be some scientific b... Read More

Turning Food Waste Into Fuel Takes Gumption And Trillions Of Bacteria

Every year, Americans send millions of tons of food to the landfill. What if you could use all of those pizza crusts and rotten vegetables to heat your home? That's already happening in one unlikely laboratory: the Newtown Creek Wastewater Treatment Plant in Brooklyn.

Gut Microbes Respond within Days to Major Diet Changes

Microbiologists have known for some time that different diets produce different gut flora, but new research indicates that the changes take hold with startling quickness. Bacterial populations shift measurably in the first few days following a big shift in what we eat, according to a recent stud... Read More

Secrets of the Giant, Ancient, Frozen, Killer Virus

It all started with a tiny chunk of dirt. The sample of 30,000-year-old permafrost, a frozen layer of soil from the Siberian tundra, weighed just a fraction of an ounce. But, as TIME reported on Tuesday, that scrap was carrying within it a surprise worthy of a pulp comic book: a gargantuan virus... Read More
