Patients with history of skin infection more likely to develop surgical site infections

Johns Hopkins scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat, published in the May issue of Nature Chemical Biology, could eventually help researchers create computers that use cells as tiny circuits.

Rwanda accelerates fight against rotavirus

Rwanda today accelerated its fight against rotavirus, the primary cause of deadly diarrhea in young children, when it became the fourth African country to introduce new rotavirus vaccines only recently made available to developing countries. Rotavirus is the primary cause of diarrhea in children. In Rwanda, diarrhea accounts for approximately 23% of child deaths.

Overgrowth of bacteria in the gut linked to IBS

An overgrowth of bacteria in the gut has been definitively linked to Irritable Bowel Syndrome in the results of a new Cedars-Sinai study which used cultures from the small intestine. This is the first study to use this "gold standard" method of connecting bacteria to the cause of the disease that affects an estimated 30 million people in the United States.

'Killer silk' can kill anthrax in minutes

The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes a simple, inexpensive dip-and-dry treatment can convert ordinary silk into a fabric that kills disease-causing bacteria - even the armor-coated spores of microbes like anthrax - in minutes.

BBSRC allocates £250M for strategic investment programmes

Minister for Universities and Science, David Willetts, will today announce substantial funding that will ensure the UK's bioscience research base remains globally competitive and at the forefront of meeting the grand challenges faced by society in the coming decades. The announcement will be made by the Minister during a visit to the Babraham Research Campus, near Cambridge, and highlighted again during a major speech at the University of East Anglia in Norwich.

Fever during pregnancy associated with autism or developmental delay

A team of UC Davis researchers has found that mothers who had fevers during their pregnancies were more than twice as likely to have a child with autism or developmental delay than were mothers of typically developing children, and that taking medication to treat fever countered its effect.

Cyanobacterium produces compounds that could treat chronic inflammatory conditions

A seaweed considered a threat to the healthy growth of coral reefs in Hawaii may possess the ability to produce substances that could one day treat human diseases, a new study led by scientists at Scripps Institution of Oceanography at UC San Diego has revealed.

Silver nanoparticles have high affinity for E. coli bacteria

Porous ceramic water filters are often coated with colloidal silver, which prevents the growth of microbes trapped in the micro- and nano-scale pores of the filter. Other metals such as copper and zinc have also been shown to exhibit anti-microbial activity.

Oestrogen promotes presence of 'mucoid' form of P. aeruginosa in women with CF

Researchers from the Respiratory Research Division of the Department of Medicine, Royal College of Surgeons in Ireland (RCSI) have published a study which represents a major breakthrough in understanding why females with cystic fibrosis do worse than males.

New method can screen for bacterial genes that are expressed during meningitis

Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromised patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

COPD patients with P. aeruginosa infection more likely to have poor clinical outcomes

Patients with chronic obstructive pulmonary disease (COPD) who become infected with the bacterium Pseudomonas aerguinosa are more likely to have worse clinical outcomes and experience more hospitalizations during the course of their disease than COPD patients who are not infected, according to researchers from Buffalo, N.Y.
