Pacific Northwest researchers have developed In-Situ Redox Manipulation (ISRM) to remove deadly contaminants from groundwater. ISRM has been shown to be effective in removing chromate, technetium, and chlorinated solvents at levels below drinking water standards.
Research found that spices can inhibit the growth of E. coli O157:H7 in ground meat and salami, with garlic showing the highest effectiveness. While spices may not eliminate the pathogen, they could add an extra layer of safety to food handling and cooking.
Researchers have developed a method to multiply and mature neural stem cells in the lab, which can form dopamine-producing neurons and reduce symptoms in an animal model of Parkinson's disease. The study opens up new opportunities for studying brain development and may lead to the creation of easily controlled stem cell therapies.
The National Institute on Drug Abuse (NIDA) is hosting a two-day national conference to discuss the latest scientific research on nicotine addiction. The conference will highlight the behavioral and neurobiological bases of nicotine addiction, as well as state-of-the-art treatment strategies and prevention methods.
Scientists discuss ways to use lightweight materials like hydrogen, boron, and lithium for radiation shielding. Researchers also explore using composites and polyamide binders for efficient protection against space radiation.
Researchers at Penn State found that sex hormones have little effect on adolescent sexual behavior after a nearly two-year study. Social factors like peer pressure are believed to have a much larger impact on behavior.
Researchers found that HIV establishes a pool of latently infected immune system cells even with early treatment. These cells can persist for years, posing an obstacle to ultimate control and eradication of the virus. The study suggests that these reservoirs are established very early in infection.
