Most of us dont pay much attention to earthworms but maybe we should. New research suggests that non-native earthworms are radically changing the forest floor in the northern U.S., threatening the goblin fern and other rare plants in the process.
This is “the first research to show that exotic earthworms are harmful to rare native vegetation in northern forests,” says Michael Gundale of Michigan Technological University in Houghton, who presents this work in the December issue of Conservat
Tethered Robotic Sub Helps Engineers Refine Computerized Navigation, Control Systems
In a new indoor tank filled with almost 43,000 gallons of water, Johns Hopkins engineers are developing and testing computer control systems to serve as the “brains” for some of the world’s leading deep sea robotic exploration vehicles. To promote advances in underwater robotics, the Whiting School of Engineering recently constructed the circular hydrodynamics tank, 14 feet deep and 25 feet in diamet
Work funded with $1.59-million from the National Science Foundation
Highly acidic drainage from an abandoned sulfide mine in Rowe is slowly cleaning itself over time, and an interdisciplinary research team from the University of Massachusetts Amherst is studying why. The group brings together experts from the fields of microbiology, geology, engineering, and science education, to determine the extent and rate of bioremediation. Researchers say their findings may enable quicker natura
Indiana University information technology experts working with others from the states leading educational institutions presented several new tools in high-performance computing, networks and visualization this week to colleagues at the international Supercomputing2002 conference. Among the tools demonstrated were a system that can track the physical location of wireless devices and a powerful mapping application.
The contributions of IU and its Research in Indiana (http://www.research-
Major international research programme on Life as learning
Mobile phones are the new learning tools of the future
Mobile phones look set to become an important new learning tool for the future. One of the projects under the umbrella of the Academy of Finland international research programme Life as Learning (or LEARN for short) is working on theoretical models and practical applications that will facilitate the use of mobile technology in learning. In charge of this project is Pro
USGS-funded research weighs benefits of forest thinning on plants and animals
Recent studies show that thinning of young forests can benefit the development of old-growth characteristics and the diversity of plants and animals, but only if methods are used that protect and promote the development of shrubs, hardwoods, and large or old trees.
The findings, which were made by researchers from the U.S. Geological Survey (USGS) and Oregon State University (OSU), hold special sig
