The advice to ’sleep on it’ for a while isn’t a bad idea, according to a new study done in part by University of Alberta researchers. Findings published in the December Journal of Sleep Research show that there may be an advantage to dreams that occur for up to a week after a memorable emotional event.

A study conducted by the University of Alberta and the University of Montreal of 470 psychology students revealed that not only do remembered events influence dreams

University of Nevada study finds plants assimilate mercury from air

Mercury gets around. A naturally occurring contaminant, mercury is found in water and soil but scientists are not exactly sure how mercury makes its way through the environment. Concerns over increasing levels of mercury contamination have sparked fish consumption advisories in certain areas.

Knowing how mercury ends up in these locations, however, is an area of concern for environmental scientists

Agents designed to attack blood vessels that feed a growing tumor are effective against tumor growth in laboratory experiments. However, results of early clinical trials with these inhibitors have not yet exhibited the same success observed in animal models. Now, a new study published in the December issue of Cancer Cell demonstrates that a unique time period exists during which combined radiation and antiangiogenic therapy can exert a remarkable synergistic effect that significantly slows tumor

The costs of caring for elderly Florida patients hospitalized for colon surgery are not reduced by Medicare HMOs, report University of South Florida researchers in the December issue of the Archives of Surgery.

Despite significantly shorter hospital stays, Medicare HMO beneficiaries who underwent colon resections — surgery to remove a diseased section of the large intestines — incurred the same overall hospital charges as patients covered by traditional fee-for-service Medica

Emergency department patients with unmet substance abuse treatment need generate much higher hospital and emergency department charges than patients without such need, according to a new study to be published today as an advance online publication of Annals of Emergency Medicine (Unmet Substance Abuse Treatment Need, Health Services Utilization, and Cost: A Population-Based Emergency Department Study).

Experiments led by Nicolas Dauphas of the University of Chicago and Chicago’s Field Museum have validated some controversial rocks from Greenland as the potential site for the earliest evidence of life on Earth.

“The samples that I have studied are extremely controversial,” said Dauphas, an Assistant Professor in Geophysical Sciences at the University of Chicago and a Field Museum Associate. Some scientists have claimed that these rocks from Greenland’s banded iron for
