Danish authors of a study in this week’s issue of THE LANCET provide reassurance to pregnant women—maternal fever in the early stages of pregnancy is probably not a risk factor for miscarriage or stillbirth.

Increased maternal body temperature can cause fetal death in some animals, which has lead to the suspicion that maternal fever early in pregnancy (when embryonic development is at a critical stage) could have a similar effect in the human population.

From 800 km in space, you would have to squint really hard to see one of these – a micron-sized phytoplankton and its armoured shell. But when a lot of them get together, say, a few trillion or so…

…what you see is the image below from the European Space Agency’s Medium Resolution Imaging Spectrometer (MERIS) instrument. The sensor, carried onboard the Envisat satellite, acquired imagery of a phytoplankton bloom that occurred this summer in the north Atlantic, off the coasts of Nova Scotia

A new study of elderly Americans shows a strong link between air pollution and higher costs of medical care, both inpatient and outpatient, and especially for respiratory ailments.

Millions of Medicare records of whites between the ages of 65 and 84 from 1989 to 1991 provided a study sample for researchers Victor R. Fuchs, professor emeritus at Stanford University, and Sarah Rosen Franks, a doctoral student at the University of California, Berkeley. They write in the November/December issue

Researchers from Midwestern University in Illinois, Curtin University of Technology in Australia, and Illinois State University have found that when bacteria become resistant to pine oil cleaners (POC), a common household disinfectant, they may also be resistant to some antibiotics. Their findings appear in the November 2002 issue of Applied and Environmental Microbiology.

In the study, POC-resistant Staphylococcus aureus were found to also be resistant to the antibiotics, vancomycin and ox

Radioactive spheres delivered via blood flow to tumor

Vanderbilt University Medical Center is offering the latest advancement for treating inoperable liver tumors.

Selective Internal Radiation Therapy (SIRT) targets a very high radiation dose to tumors within the liver, regardless of their cell of origin, number, size or location. The procedure uses biocompatible radioactive microspheres (SIR-Spheres®) that contain yttrium-90 and emit high energy beta radiation.

Scientists at the University of Pennsylvania have averted the onset of neurodegenerative disease in fruit flies by administering medication to flies genetically predisposed to a disorder akin to Parkinson’s disease.

The result suggests a new approach to the treatment of human disorders including Parkinson’s and Alzheimer’s diseases. Penn biologist Nancy M. Bonini and graduate student Pavan K. Auluck report the finding in the November issue of Nature Medicine.
