An evaluation of 25 patients and a review of reports of clinical, biological and experimental data suggest that over-the-counter, homeopathic nasal zinc therapies may be associated with a reduced sense of smell, according to a new study.

When a summer heat wave engulfs New York City, people seek the soothing embrace of water in whatever way they can: they swarm the neighborhood swimming pool; they visit the beach at Coney Island; they take multiple showers. People also tap into the city's water supply through some of its most vulnerable access points: fire hydrants. Wrenching open fire hydrants to frolic in the resulting spray is a summertime custom in cities and suburbs nationwide--often with unconsidered consequences. [More]

The process of removing land mines from a current or former war zone is a dangerous, time-intensive and expensive proposition thanks largely to antiquated technology and methods of detection and extraction. An international team of researchers and engineers is hoping to change this with the help of a holographic radar system that sends continuous microwaves into the ground and creates subterranean images revealing what lies buried in a particular area.

While polar bears flounder in the face of shrinking ice floes, another furry creature has gotten a boost from climate change. In the past three decades yellow-bellied marmots ( Marmota flaviventris ) have been fruitful--and multiplied--thanks to longer summers, according to a new study. [More]

The sepals of the plant Arabidopsis thaliana -- commonly known as the mouse-eared cress -- are characterized by an outer layer of cells that vary widely in their sizes, and are distributed in equally varied patterns and proportions. Scientists have long wondered how the plant regulates cell division to create these patterns. Melding time-lapse imaging and computer modeling, a team of scientists has provided a somewhat unexpected answer to this question.

A technique that combines nanotechnology with adult stem cells appears to destroy atherosclerotic plaque and rejuvenate the arteries, according to a new study.
