Mineralization of sand particles boosts microbial water filtration

Mineralization of sand particles boosts microbial water filtration

Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Microbiology . These findings resoundingly refute, for the first time, the conventional wisdom that the mineral deposits interfere with microbial colonization of the sand particles Continue reading

Effect of antibiotic susceptibility for patients with bloodstream infection

Effect of antibiotic susceptibility for patients with bloodstream infection

In an analysis of more than 8,000 episodes of Staphylococcus aureus bloodstream infections, there were no significant differences in the risk of death when comparing patients exhibiting less susceptibility to the antibiotic vancomycin to patients with more vancomycin susceptible strains of S.

Fundamental theory about education of immune police questioned by researchers

Fundamental theory about education of immune police questioned by researchers

A fundamental theory about how our thymus educates our immune police appears to be wrong, scientists say. It’s known that stem cells come out of the bone marrow and travel to the tiny thymus gland behind the breastbone to learn to become one of two CD4T cell types: one leads an attack, the other keeps the peace. One widely held concept of why they become one or the other is that, despite coming from the same neighborhood and going to the same school, they are exposed to different things in the thymus, said Dr. Continue reading

New vaccines targeting adults, teens are best chance to eliminate TB by 2050

New vaccines targeting adults, teens are best chance to eliminate TB by 2050

Targets to eliminate tuberculosis (TB) by 2050 are more likely to be met if new vaccines are developed for adults and adolescents instead of for infants, according to new research published in the journal Proceedings of the National Academy of Sciences . Continue reading

Healthy knowledge management and social networking

Healthy knowledge management and social networking

Social network analysis could improve knowledge sharing in the healthcare sector, according to research results published in the International Journal of Collaborative Enterprise . Elizabeth Cudney, Steven Corns and Suzanna Long in the department of Engineering Management and Systems Engineering at Missouri University of Science and Technology, in Rolla, Missouri, USA, explain how knowledge management systems (KMS) can be critical in capturing, retaining and communicating project results and staff knowledge Continue reading

New discovery in the microbiology of serious human disease

New discovery in the microbiology of serious human disease

Previously undiscovered secrets of how human cells interact with a bacterium which causes a serious human disease have been revealed in new research by microbiologists at The University of Nottingham. The scientists at the University’s Centre for Biomolecular Sciences have shed new light on how two proteins found on many human cells are targeted by the human pathogen Neisseria meningitidis which can cause life-threatening meningitis and septicaemia Continue reading

Link between depression, abnormal brain response to visceral pain in patients with IBS

Link between depression, abnormal brain response to visceral pain in patients with IBS

High rates of anxiety and depression amongst patients with irritable bowel syndrome (IBS) have led many researchers to believe there could be a causal relationship between psychological factors and IBS symptoms. Now, scientists in Germany have found clear evidence that patients with IBS process pain signals from the gut abnormally, and that disturbed brain responses to pain are particularly pronounced in patients with more depression symptoms.

ZEB1: Oscar for leading role in fat storage

ZEB1: Oscar for leading role in fat storage

A team from EPFL, in collaboration with ETH Zurich, has managed to decode the process of adipogenesis by identifying the precise proteins that play the leading roles in fat absorption. Their findings have been published in the open-access scientific journal eLife Continue reading

Disease decoded: Gene mutation may lead to development of new cancer drugs

Disease decoded: Gene mutation may lead to development of new cancer drugs

The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the University of Michigan and the U-M Health System recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can’t regenerate and make new blood Continue reading
