Across a range of media, women and girls are more likely to be depicted as concerned with romance and dating than work or school, and their appearance is frequently a focus of attention. Yet, females in the media also often are shown using intelligence and exerting independence, a UD researcher reported.

The CSM also becomes part of the Smithsonian's Permanent Research Collection.
Three tips from Los Alamos: 1. Acoustic octane ratings 2. Carbon monoxide sensors 3. Plutonium coatings
Consider the escape mechanism of the lowly tadpole. Sensing drought or a shrinking food supply in its home pond, the tadpole produces a hormone that accelerates its transformation into a toad or frog.
A scientific breakthrough that could eventually become as important as X-ray and radar technologies may soon make it possible to see images of diseased tissue, electric fields, plastic explosives hidden in a suitcase, and much more that is undetected by other imaging systems. Called real-time electro-optic terahertz sensing, the technology was invented under the leadership of Xi-Cheng Zhang, associate professor of physics at Rensselaer Polytechnic Institute.
The idea that problem drinkers can simply cut back instead of cutting themselves off is the premise behind, the Guided Self-Change Clinic at Nova Southeastern University.
Organizations use hazing because "induction-begets devotion." Research by Caroline Keating, professor of psychology at Colgate University in Hamilton, NY, shows that severe treatment of initiates seems to enhance their commitment to the group. Her research shows that the harsher the hazing, the more attractive and competent group members seem to the initiates and the more initiates conform to the group.

A new device may help researchers better understand environmental events such as global warming by measuring individual aerosol particles as small as 10 nanometers--roughly one order of magnitude smaller than existing transportable instruments, say University of Delaware researchers who recently filed a patent disclosure. The instrument analyzes particles "at the critical early stages of their growth," before they accumulate in clouds, says Anthony S. Wexler, associate professor of mechanical engineering.
Because virtually all of today's information technology is computer-driven, there is a huge demand for computer software engineers in just about any field a college-bound high school student can name.
Purdue University researcher Samuel Wagstaff is using powerful computers to divide and conquer numbers that have more than 100 digits. Results from the latest round, factoring a record-setting 167-digit number, may help scientists develop secret codes for computer security.
A team of University of Minnesota researchers has regenerated functioning nerve cells from cervical (neck) nerve tissue taken from young rats, whose spinal cords were once thought unable to grow new nerve cells.
Hormones are being found to have impacts beyond the individual animal that produces them. They reach from one generation to effect the very survival of the next. In addition, they communicate messages about the environmental conditions affecting the parent generation to the offspring -- which may help the new generation adapt to their environment.
A pending patent, filed for by two researchers at the University of Georgiaπs Savannah River Ecology Laboratory, could reduce cleanup costs by millions of dollars at U.S. Department of Energy facilities across the country and make the most commonly used groundwater remediation technology process much more effective.

An agreement also would begin the process of upgrading food-systems infrastructures and training within developing countries.
Superintendents of the nationÃs largest urban school districts will announce the formation of a national coalition to develop and share solutions to common problems they face in improving mathematics and science education. Revitalizing urban schooling is a key to the success of national education reform programs because urban school systems enroll roughly half of all U.S. public school students.

Based in the College of Veterinary Medicine, the institute will provide financial support for studies by Cornell-affiliated researchers and will bring to campus speakers on a range of animal-welfare topics.
Astronomers are having a difficult time explaining how a distant galaxy can emit gamma rays at extremely high energies. The galaxy, called Markarian 421, is challenging conventional astronomical theories of particl acceleration processes driven by black holes. The observations also indicate that the universe is not as opaque at these energies as previosuly thought.
The solution to the growing environmental problem of scrap tires may well be found on the football field - or a golf course or a well-worn yard. The U.S. Patent Office on April 22 will issue a patent to Michigan State University to use crumb rubber as a turf topdressing. MSU turfgrass researchers discovered that working tires into the soil -- after grinding them into crumbs -- solves a thorny disposal problem while improving grass and athletic fields that get a lot of wear and tear.

The universe, like the Earth, may have its own axis, according to observational data collected by researchers at the University of Kansas and University of Rochester in New York. The research brings into question Albert Einstein's "Theory of Relativity," which is based on assumptions of a centerless, directionless universe, as well as upon the constancy of the speed of light.
