A three-dimensional view of the fine bones, nerves, and hollow spaces in the human ear--from any vantage point inside or outside the organ-- is now possible, thanks to a virtual model constructed by a team of researchers at the University of Illinois at Chicago. The model--explored using a wand and a special pair of eyeglasses while facing a 20-square-foot screen--allows surgeons to familiarize themselves with the complex spatial relationships of structures composing the ear.
At a recent conference on "data mining" at the University of Illinois at Chicago, experts from around the world witnessed a first in the use of the next generation of network communications. The demonstration of data mining--the automatic search for patterns, asociations, and changes in large databases--is important because it showed data mining shows data mining can be done over a wide geographic area.

"Most issues that relate to families also relate to family- owned businesses," says Doug Sprenkle, Purdue University professor of child development and family studies. When problems in the workplace involve the family relationships of the participants, standard business advice is of limited value, he says.
A comparison of data on fast-food consumption and rising obesity has found a surprising wrinkle: There doesn't appear to be much of a link, at least in terms of large populations.
Injuries continue to have a major impact on the health of Americans, according to the latest federal government report on the nation's health, issued today by HHS Secretary Donna E. Shalala.
Remote islands of surreal beauty, the foggy, windswept Aleutians are thousands of miles from heavily populated areas. Even so, the islands harbor a nasty reminder of human activity: Sea otters and bald eagle eggs from the western Aleutians carry potentially harmful levels of DDT and other contaminants.

Researchers have found a way of controlling a tailor-made version of a protein that gives the glow to the Pacific Northwest jellyfish. The discovery not only sheds light on the inner workings of the green fluorescent protein (GFP) of the jellyfish Aequorea victoria, it also suggests a potential new way for storing and accessing computer memories in packages the size of a single molecule.
Using electron-beam lithography, researchers at the Cornell University Nanofabrication Facility have built what they believe are the world's smallest mechanical devices, including a Fabry-Perot interferometer and, for fun, the world's smallest guitar, carved out of crystalline silicon and no larger than a single cell. The technology that could have a variety of uses in fiber optics, displays, sensors and electronics. Mechanical force probes can be made much smaller than a single cell, and forces associated with single biological molecules could be measured.
A gene linked to the most common abdominal cancer in children also may contribute to the development of breast cancer, according to a study at the University of California, Santa Cruz, and Oregon Health Sciences University.

IOWA CITY, Iowa -- Repeated exposure to molds often found in damp hay and grain can irritate the lungs causing a disease known as farmer's lung or hypersensitivity pneumonitis. The syndrome causes coughing and shortness of breath, and is "reasonably common in the Midwest," says Dr. Gary Hunninghake, University of Iowa professor of internal medicine, who has studied the disease for many years.
Breeding trees that can be more easily processed into paper, with less harm to the environment, has long been a goal of researchers. Now, thanks to the discovery of abnormal, brown-colored wood in a mutant pine tree, scientists at North Carolina State University may be a step closer to achieving that goal.

A study of first and second-generation African Caribbeans living in England found many undiagnosed cases of high blood pressure and more whose blood pressure medications were not adequately controlling their hypertension. It is the first study to focus on blood pressure, dietary salt and salt sensitivity among first and second-generation African Caribbeans living in the United Kingdom.
British colleagues warned Baltimore hypertension researcher Dr. Elijah Saunders that he would not be able to recruit enough African Caribbeans for a study of high blood pressure and dietary salt. He not only signed up the 150 he needed, he has 200 more waiting in line.
Sales managers have low expectations when African-Americans apply for professional sales jobs, but according to a study conducted at the University of South Florida, that can have a paradoxical effect: interested, qualified African-Americans may be seen as even more qualified than equally-qualified Caucasians.
Atlantic City, N.J., was a relative cool spot as it broke five low temperature records and tied another in June, while Baltimore tallied three low temperature records, and Charleston, W. Va., marked its first 90-degree reading in more than a year, according to the climatologists at the Northeast Regional Climate Center at Cornell University.
Elevated levels of carbon dioxide in the atmosphere benefit some plants by making them more tolerant to cold temperatures. If carbon dioxide levels double within the next century as we are expecting, some plant species should be able to withstand temperatures a few degrees cooler than they can now. Northeastern farmers and home gardeners may be able to plant some crops earlier in the spring. This will also affect the distribution and mixture of species.
