Screening existing drugs to uncover new weapons against antibiotic-resistant bacteria

Bacteria that are resistant to standard antibiotics represent one of the biggest threats to global health today, and one particular type, known as carbapenem-resistant Enterobacteriaceae (CRE), was recently classified by the US Centers for Disease Control and Prevention as having the most urgent antimicrobial resistance threat level possible. Help might just be at hand though, with researchers from the Beth Israel Deaconess Medical Center (BIDMC) using a screening method to identify existing drugs that might well prove effective against the dangerous bacteria.Read More

Urine-powered battery offers cheap energy source

When most people think of bacteria and urine together, chances are good they think of a not-so-pleasant infection. For researchers at the University of Bath however, putting these two thoughts together led to the development of a battery that could harness "pee power" to bring energy to parts of the world that might not otherwise have access to it.Read More

Experimental battery charges and recharges via bacteria

Inside your body, the wrong kind of bacteria can sap you of energy. Inside a battery, however, it turns out that the right kind of bacteria can cause an energy boost that might be able to help power our lives. That's the finding from researchers in the Netherlands, who've just developed a bacteria-based battery that they were able to charge and discharge 15 times in a row.

Dramatic 3D images reveal super-small motors that drive bacteria

When you want to get together with friends or family, chances are you employ a motor. That is to say, you likely get into a car or on some form of public transport to arrive at a meeting point. Bacteria really aren't very different. They have various means of getting around, but they all involve some kind of biological motor — and those motors have just been imaged in dramatic and colorful 3D by researchers at the California Institute of Technology (Caltech).Read More

Lasers combine with gold nanodisks to fry bacteria within seconds

On any given day, around one in 25 hospital patients in the US will fall victim to healthcare associated infection, according to the Center for Disease Control and Prevention. Antibiotics and current sterilization methods can provide some respite from the spread of harmful bacteria, but they do have their pitfalls. Researchers have developed a new approach to killing off these germs that may provide a more efficient path forward, using porous gold nanodisks and infrared light to destroy them in a matter of seconds.

E. coli bacteria produce a "green" blue dye

In its traditional form, the textiles industry isn't exactly a poster child for eco-friendliness – this is largely due to the widespread use of toxic synthetic dyes. That's why there's an increasing demand for less harmful, natural alternatives. Just such an alternative has recently been developed by scientists at Utah State University, who discovered that E. coli bacteria can produce a deep blue dye known as indigoidine.Read More

Dangerous bacteria molecules discovered in processed foods

Everyone knows that processed foods aren't exactly good for the human body, but a new study by researchers at the University of Leicester has shed more light on exactly why that's the case. The scientists have detected dangerous molecules called pathogen-associated molecular patterns (PAMPs), which are linked to numerous conditions, including Type 2 diabetes. Perhaps most interestingly, it is believed that the dangerous molecules could potentially be removed without impacting cost or taste.Read More

Natural clay found to kill deadly bacteria

A global effort is under way to find effective treatments for deadly hospital-acquired infections, with many such dangerous bacteria proving worryingly resistant to antibiotics. Now, help may have been found in the most unlikely of places, with researchers finding positive results when studying an old folk remedy – natural Canadian clay.Read More
