People in northern latitudes have greater proportion of obesity-related bacteria in gut

People living in cold, northern latitudes have bacteria in their guts that may predispose them to obesity, according to a new study by researchers at the University of California, Berkeley, and the University of Arizona, Tucson.

Improper handling of intravenous saline leads to rare bacteria outbreak

Improper handling of intravenous saline at a West Virginia outpatient oncology clinic was linked with the first reported outbreak of Tsukamurella spp., gram-positive bacteria that rarely cause disease in humans, in a new report from the Centers for Disease Control and Prevention (CDC). The report was published in the March issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

University of Liège joins IMI programme to develop new antibiotics against Gram-negative pathogens

More than 30 European universities and companies, led by GlaxoSmithKline, are joining forces in a six-year programme funded by the Innovative Medicines Initiative (IMI) for the sum of EUR 85 millions with the aim of developing new antibiotics against Gram-negative pathogens.

Elusive progenitor cells that give rise to ILCs identified in fetal liver and bone marrow of mice

The elusive progenitor cells that give rise to innate lymphoid cells-a recently discovered group of infection-fighting white blood cells-have been identified in fetal liver and adult bone marrow of mice, researchers from the University of Chicago report early online in the journal Nature.

Researchers develop new model for isolating effects of nutrients on gene expression, physiology

Everyday our cells take in nutrients from food and convert them into the building blocks that make life possible. However, it has been challenging to pinpoint exactly how a single nutrient or vitamin changes gene expression and physiology.

Two new mechanisms open alternative approaches to antibiotics development

The first mechanism disrupts the arrangement of amino acids required for the cohesion of the protease subunits. As a result the protease breaks into two parts. The second acts directly on the core of the active center.

Researchers discover how beneficial bacteria in guts communicate with own cells

Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.

Researchers reveal how genome-editing tool works as 'guided missile' to correct errors in genetic code

Researchers from the Broad Institute and MIT have teamed up with colleagues from the University of Tokyo to form the first high definition picture of the Cas9 complex - a key part of the CRISPR-Cas system used by scientists as a genome-editing tool to silence genes and probe the biology of cells. Their findings, which are reported this week in Cell, are expected to help researchers refine and further engineer the tool to accelerate genomic research and bring the technology closer to use in the treatment of human genetic disease.

Study uncovers how gut bacteria metabolize complex dietary carbohydrates in fruits, vegetables

We are all aware of the health benefits of dietary fiber. But what is dietary fiber and how do we metabolize it?

Drive for novel antibiotics against gram-negative bacteria

Over 30 European universities, research institutes, and companies, led by GlaxoSmithKline and Uppsala University, are joining forces in a 6 year programme supported by the Innovative Medicines Initiative (IMI) to develop novel antibiotics against Gram-negative pathogens.

Researchers learn about the impact invasive zebra mussels have on risk of algae blooms

Researchers at Grand Valley State University's Annis Water Resources Institute are learning more about the impact invasive zebra mussels and native aquatic insect larvae have on the risk of algae blooms in two West Michigan lakes. The results of the research will be published in the journal Oikos.

Scientists receive €85 million international drive to develop new and effective drugs

An increasing biological resistance to antibiotics treatment is to be countered by Aston University scientists who will lead a €85 million international drive to develop new and effective drugs.

Researchers examine how evolution relates to health

February 12 marks the birth of the 19th century naturalist Charles Darwin, who launched the scientific study of evolution. While Darwin's theory laid the groundwork, ongoing studies have deepened our understanding of evolution, including how it relates to health. Research funded by the National Institutes of Health has helped answer many questions about evolution, health and medicine. Here's a sampling.

Researchers share findings on relations between gut flora and obesity

Cutting-edge European research presented at the 2014 AAAS meeting in Chicago. Three leading European researchers on the gut microbiome will be present at the 2014 AAAS meeting, on Saturday 15 February, to share their recent findings on the relations between gut flora and obesity, diabetes, and cardio-metabolic diseases in general.

Researchers shed new light on pain associated with bacterial infections

Components in the outer wall of bacteria directly activate pain sensors, triggering immediate pain and inflammatory responses. This finding by a multinational team of researchers led by Professor Karel Talavera (KU Leuven, Belgium) and Professor Félix Viana (Institute of Neuroscience, Spain) sheds new light on pain associated with bacterial infections and reveals a new target for drugs designed to treat them.

Optogenetics technique allows scientists to control neurons' electrical activity

Optogenetics is a technique that allows scientists to control neurons' electrical activity with light by engineering them to express light-sensitive proteins. Within the past decade, it has become a very powerful tool for discovering the functions of different types of cells in the brain.

Novel combined therapy for treatment of septic patients in ICU

Septic shock is caused by excessive and systemic reaction of the entire body against infectious agents, in most cases of bacterial origin. The number of deaths by septic shock in intensive care units is very high and is still increasing, despite numerous large scale clinical trials.

Some neurologic diseases associated with prenatal exposure to inflammatory immune responses

Johns Hopkins researchers report that fetal mice — especially males — show signs of brain damage that lasts into their adulthood when they are exposed in the womb to a maternal immune system kicked into high gear by a serious infection or other malady. The findings suggest that some neurologic diseases in humans could be similarly rooted in prenatal exposure to inflammatory immune responses.
