Researchers Engineer Gut Bacteria to Generate Renewable Propane

Researchers used Escherichia coli to interrupt the biological process that turns fatty acids into cell membranes, channeling the fatty acids along a different biological pathway so that the bacteria made engine-ready renewable propane instead of cell membranes. The development is a step towards commercial production of a source of fuel that could one day provide […]

Researchers Identify Gut Bacteria That Protects Against Food Allergies

A newly published study from the University of Chicago reveals that the common gut bacteria Clostridia prevent sensitization to allergens in a mouse model, paving the way for probiotic therapies to treat food allergies. The presence of Clostridia, a common class of gut bacteria, protects against food allergies, a new study in mice finds. By […]

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. There have been plenty of fad diets that captured the public’s imagination over the years, but Harvard scientists have identified what may be […]

Scientists Discover Lowest Temperature Limit for Life on Earth

In a new study, scientists reveal that -20°C is the lowest temperature at which simple life can live and grow on Earth. The study, which is published in PLoS One, reveals that below -20°C, single-celled organisms dehydrate, sending them into a vitrified – glass-like – state during which they are unable to complete their life […]

Study Reveals Changing Gut Bacteria Through Diet Affects Brain Function

A newly published study found that women who regularly consumed beneficial bacteria known as probiotics through yogurt showed altered brain function in many areas, including those involved in sensory processing. UCLA researchers now have the first evidence that bacteria ingested in food can affect brain function in humans. In an early proof-of-concept study of healthy […]

How Deadly Bacteria Trick the Immune System

A new study from UCLA suggests that certain bacteria can pretend to be viruses when infecting humans, allowing them to hijack the body’s immune response so that they can hide inside cells. An outbreak of tuberculosis in the skid row area of downtown Los Angeles may have exposed up to 4,500 individuals to the bacterium […]

Study Shows Viruses Can Have Immune Systems

In a newly published study, researchers at Tufts University School of Medicine provide evidence that bacteriophage can acquire a functional and adaptive immune system, possibly opening the door for new phage therapies to treat bacterial diseases. Boston — A study published today in the journal Nature reports that a viral predator of the cholera bacteria […]

Ancient Teeth Bacteria Record Disease Evolution

A newly published study from the University of Adelaide shows that calcified dental plaque (dental calculus) found on ancient teeth from 34 early European skeletons indicates that the transition from hunter-gatherer to farming shifted the oral microbial community to a disease-associated configuration. DNA preserved in calcified bacteria on the teeth of ancient human skeletons has […]

Natural Toxins Could Disarm Cancer and Drug Resistant Bacteria

Researchers at Rice University believe that combining natural toxins with man-made mirror drugs will create the drug equivalent of a one-two punch, “confusing” bacteria and cancer and preventing them from rapidly becoming resistant to the man-made drugs. Cancer researchers from Rice University suggest that a new man-made drug that’s already proven effective at killing cancer […]

Staphylococcus Aureus

Fighting to stop deadly infections like Staphylococcus aureus, scientists have now identified the structural basis for antibiotic multiresistance acquisition by S. aureus and suggest ways to potentially stop the transfer. Worldwide, many strains of the bacterium Staphylococus aureus are already resistant to all antibiotics except vancomycin. But as bacteria are becoming resistant to this once […]
