Research to develop a narrow-spectrum antibiotic that can target a particular species of bacteria without harming the other "good" bacteria present was described at the Society for General Microbiology meeting at Harrogate today (Thursday April 2).
Using probiotics successfully against a number of animal diseases has helped scientists from University College Cork, Ireland to understand some of the ways in which they work, which could lead to them using probiotics to prevent and even to treat human diseases.
A quicker, cheaper and more accurate test for deadly Aspergillus fumigatus fungal infections in patients with damaged or suppressed immune systems was described today, (Thursday 2 April) at the Society for General Microbiology meeting in Harrogate, by Dr Christopher Thornton from the University of Exeter, UK.
Bacterial infection of mung bean seeds can cause outbreaks of food poisoning when the sprouts are eaten. Now research by a microbiologist from Nottingham University, UK has shown ways of disinfecting the bean seeds using natural methods and which do not prevent the beans from sprouting.
New York, NY, April 1, 2009—One of five Medicare beneficiaries discharged from the hospital is readmitted within 30 days, and half of non-surgical patients are readmitted to the hospital without having seen an outpatient doctor in follow-up, according to a Commonwealth Fund-supported study in today's New England Journal of Medicine. All told, unplanned rehospitalizations cost Medicare $17.4 billion in 2004, the study says. The study, "Rehospitalizations Among Patients in the Medicare Fee-for-Service Program," by Stephen Jencks, M.D., M.P.H., Mark V. Williams, M.D., and Eric A.
CHICAGO—When a patient is discharged from the hospital, just about the last thing he or she wants is to be back in again within the next month. But a new national study has found that's exactly what happens to one out of five Medicare patients, costing billions in health care and suffering for patients.
The study, coauthored by a researcher from the Northwestern University Feinberg School of Medicine, also found that more than half the patients rehospitalized within 30 days appear not to have seen a physician as an outpatient since they were released from the hospital.
April 1, 2009 – It has long been known that red wine causes teeth to stain. But white wine? A recent study by NYU dental researchers found that drinking white wine can also increase the potential for teeth to take on dark stains.
The researchers compared two sets of six cow teeth, whose surface closely resembles that of human teeth, and used a spectrophotometer, an instrument that measures color intensities, to evaluate staining levels.
Psychologists and neurologists invest considerable effort in the study of working memory. In terms of information retention, there is a difference between long-term memory, which is affected in diseases such as Alzheimer's, and short-term or working memory, which allows us to make immediate decisions or structure a discourse. This more ephemeral memory is affected in diseases such as schizophrenia and depression, although a cause-effect relationship has not been established.
New research shows that for millions of years carbon dioxide has been stored safely and naturally in underground water in gas fields saturated with the greenhouse gas. The findings – published in Nature today – bring carbon capture and storage a step closer.
Politicians are committed to cutting levels of atmospheric carbon dioxide to slow climate change. Carbon capture and storage is one approach to cut levels of the gas until cleaner energy sources are developed.
