New research reveals Small Colony Variants (SCVs) of P. aeruginosa to be a hallmark of chronic infection in cystic fibrosis (CF) patients. Results, published March 12th in the open-access journal PLoS Pathogens, suggest that SCV-mediated persistence might be a good target for antimicrobial chemotherapy.
The secret world of inflammation is slowly being revealed by the application of advanced techniques in microscopy, as shown in a study published March 12 in the open-access journal PLoS Pathogens. Researchers at the Hull York Medical School and the University of York used 2-photon microscopy to identify how killer T lymphocytes behaved when they enter sites of inflammation caused by the parasite Leishmania donovani, and which infected cells they were able to recognise.
An international convention will meet next week to decide whether to grant requests from Tanzania and Zambia to lower the protection status of their elephants, allowing them to conduct one-time sales of stockpiled ivory.
PITTSBURGH, March 12 – Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers at the University of Pittsburgh, the University of Essex and the University of Vermont who tagged the proteins with quantum dots to watch the action unfold. The findings are available today in Molecular Cell.
In the March issue of BioScience, researchers present a sophisticated new analysis of the effects of boosting use of maize-derived ethanol on greenhouse gas emissions. The study, conducted by Thomas W. Hertel of Purdue University and five co-authors, focuses on how mandated increases in production of the biofuel in the United States will trigger land-use changes domestically and elsewhere. In response to the increased demand for maize, farmers convert additional land to crops, and this conversion can boost carbon dioxide emissions.

As shifts change in a hospital, outgoing physicians must "hand off" important information to their replacements in a brief meeting. But a new study of this hand-off process finds that the most important information is not fully conveyed in a majority of cases, even as physicians rate their communication as successful.
Elsevier, the world-leading publisher of scientific, technical and medical information products and services, today announced the launch of a new quarterly journal, Journal of Family Business Strategy (JFBS). The journal aims to be a primary publication outlet for academics and scholars in the field of family business strategic issues and the first issue is now available on ScienceDirect.
Mother birds communicate with their developing chicks before they even hatch by leaving them messages in the egg, new research by a team from the Department of Zoology, University of Cambridge, has found.
For the first time, researchers have been able to confine and study an individual protein, one that plays a key role in photosynthesis, without having to pin it down so tightly as to alter its fundamental behavior.
The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.
Women in the UK who have ever used the oral contraceptive pill are less likely to die from any cause, including all cancers and heart disease, compared with never users, according to research published on bmj.com today.
More high risk cases of human papilloma virus (HPV) could be detected by offering home testing kits to women who do not come forward for cervical screening, according to research published on bmj.com today.
