As an eyewitness sits on the stand in a courtroom recalling details of an incident, how much of what he or she remembers actually happened?

False memories are a common occurrence in the courtroom and in everyday life, and have long been considered by psychologists as a side effect of efforts to boost memory. New research from Tufts University has answered the question of how to increase memory, without also increasing corresponding false memories.

“The better we understand

Two University of Iowa Health Care physicians are calling attention to the issue of polyherbacy, the excessive or inappropriate ingestion of herbs for the treatment or prevention of disease, especially in older patients.

Jose Ness, M.D., UI assistant professor (clinical) of internal medicine, and Nicole Nisly, M.D., associate professor (clinical) of internal medicine and director of the UI Complimentary and Alternative Medicine Clinic, published a letter on polyherbacy in the May issu

Thought to be the most addictive form of nicotine in tobacco smoke, free-base nicotine is found at a wide range of levels in popular brands

When it comes to nicotine content, all cigarettes are not created equal, according to a new study by researchers at Oregon Health & Science University. In fact, the study finds that some commercial cigarette brands contain 10 to 20 times higher percentages of nicotine in the so-called “free-base” form — the form thought to be most addictive — t

Researchers have discovered a novel class of compounds that affects the cell’s garbage disposal system which degrades proteins and opens a window for understanding a vital cell function as well as for treating heart disease and cancer.

The distinctive mechanisms of these compounds are reported in the July 29 issue of Biochemistry and online earlier this month by Dr. Michael Simons, professor of medicine and of pharmacology and toxicology at Dartmouth Medical School and head of ca

A team of scientists, including several from the National Center for Atmospheric Research (NCAR), has determined that human-related emissions are largely responsible for an increase in the height of the tropopause – the boundary between the two lowest layers of the atmosphere. The research results, which will be published July 25 in the journal Science, provide additional evidence that emissions from power plants, automobiles, and other human-related (or anthropogenic) sources are having profound im

Scientists from the Lawrence Livermore National Laboratory have determined that human-induced changes in ozone and well-mixed greenhouse gases are the primary drivers of recent changes in the height of the tropopause.

Earlier research has shown that increases in the height of the tropopause over the past two decades are directly linked to stratospheric ozone depletion and increased greenhouse gases.

The new research uses climate model results to provide more quantitative est
