Mercury pollution threatens health worldwide, scientists say
Mercury pollution can threaten the health of people, fish, and wildlife everywhere, from industrial sites to remote corners of the planet, but reducing mercury use and emissions would lessen those threats, according to a declaration ratified today at an international conference on mercury pollution.

Ancient Arctic water cycles are red flags to future global warming
Ancient plant life recovered in recent Arctic Ocean sampling cores shows that at the time of the last major global warming, humidity, precipitation levels and salinity of the ocean water altered drastically, along with the elevated temperatures and levels of greenhouse gases, according to a report in the August 10 issue of Nature.

Segerstrom explores how optimists get what they want from life and how pessimists can too in her new book

More is not always better: routine screening not always beneficial
Doing more is not always better. Improving the quality of medical care does not necessarily dictate providing additional care.

The 'Good Life' elusive for middle class working couples with children
In research to be presented at the American Sociological Association's annual meeting, Phyllis Moen, McKnight presidential chair in sociology at the University of Minnesota, says that middle class couples who both work struggle to compete in job environments designed for single earners with no family responsibilities.

Wear and tear of stress: the psychoneurobiology of aging
Age may be more related to reactions to stress and the absence of disease rather than to a person's chronological age, say leading researchers in the fields of neurobiology and psychoneuroendocrinology.

Specimen radiography confirms success of MRI-guided breast biopsy
Radiologists can help confirm that an MRI-guided breast biopsy has successfully removed the lesion by taking an x-ray of the lesion and slices of the lesion, a new study shows.

Going to church to lose weight
Philadelphia residents will soon be able to monitor their weight loss online at several area churches, which will have computer stations and trained program counselors.

Exercise helps sustain mental activity as we age, may prevent dementia-like illnesses
Based on a review of studies on exercise and its effect on brain functioning in human and animal populations, researchers find that physical exercise may slow aging's effects and help people maintain cognitive abilities well into older age.

Some good advice from nurses to patients who smoke significantly increases the likelihood of those smokers quitting, according to several articles in a special issue of the July-August 2006 Nursing Research journal.

New type of optical microscopy attains near-molecular resolution
A new type of microscopy invented by Xiaowei Zhuang and colleagues at Harvard University and the Howard Hughes Medical Institute delivers spatial resolution more than 10 times better than that of conventional optical microscopes, putting scientists tantalizingly close to the first crisp, ultra-resolution, real-time imaging of living biomolecules and cells.

New method shows that neocortical nerve cells are not renewed
Most bodily organs continually die and regrow a little at a time.

Women who accept their bodies the way they are seem to be more likely to follow principles of healthy eating, new research shows.

Scientists discover age-regulated cellular activities that protect against protein aggregation
By disrupting the aging process in an organism, scientists at The Scripps Research Institute and the Salk Institute for Biological Studies have discovered two mechanisms in an animal model of Alzheimer's disease that protect cells against protein aggregation that leads to damage called

Digital surgery with touch feedback could improve medical training
Combining the sense of touch with 3-D computer models of organs, researchers at Rensselaer Polytechnic Institute are developing a new approach to training surgeons, much as pilots learn to fly on flight simulators.

Childhood obesity caused by 'toxic environment' of Western diets, study says
A UCSF researcher has determined that a key reason for the epidemic of pediatric obesity, now the most commonly diagnosed childhood ailment, is that high-calorie, low-fiber Western diets promote hormonal imbalances that encourage children to overeat.
