The Hudson Foods hamburger recall may be just what it takes to convince Americans that it's time to accept irradiation as another technique to safeguard their food supply, two Purdue experts say. Irradiation can destroy the microorganisms responsible for food-borne illnesses and extend the shelf life of perishable foods.
Monkeys on the African island of Zanzibar have learned that ingesting charcoal will counteract the adverse affects of toxic substances in their diet, say Duke University and University of Wyoming scientists.
Now that vaccination barrier zones are halting the northward spread of raccoon rabies in New York, Vermont and Ohio, Cornell University rabies-fighters are ready to extend the barriers across New Hampshire and Maine. Then the raccoon rabies vaccination could move southward, they predict, to turn back the viral disease in already-infected states.
The characteristic light flashes that summon male fireflies of the genus Photinus could come from female Photinus fireflies. Just as likely, the signaling females are from a different genus. The femmes fatales fireflies are luring unrelated males close enough to eat them. The males contain defensive chemicals that females need to repel predators, such as spiders.

Life is not only getting longer - it's getting better, thanks in large part to medicines that are helping older Americans lead active lives and maintain their independence. And 91 pharmaceutical companies are currently working on 178 medicines to treat such threats to an independent lifestyle for seniors as Alzheimer's disease, arthritis and Parkinson's disease, according to a new survey by the Pharmaceutical Research and Manufacturers of America (PhRMA). These 178 potential medicines are in addition to the more than 400 drugs in testing for heart disease, cancer and stroke - the leading killer of older Americans.
BACK TO SCHOOL WITH NSF--The National Science Foundation funds an array of programs to improve the quality of science and math education for all Americans and to ensure a steady supply of the world's best-educated scientists, mathematicians and engineers. Roughly 20 percent of the NSF's $3.3 billion annual budget is allocated to its education and human resources programs. NSF's investment represents one-third of all federal spending on math and science education.
Scientists are one step closer to identifying one of the major toxins produced by the fish-killing organism Pfiesteria piscicida, which has been blamed for killing millions of fish along the East Coast. In a series of experiments completed earlier this month, researchers at North Carolina State University have for the first time successfully isolated and purified a water-soluble toxin component from Pfiesteria.
Men who donate blood may reduce their risk of heart disease by up to 30 percent, according to a study led by David Meyers, M.D., professor of internal medicine and preventive medicine at the University of Kansas Medical Center. The study is published in the August issue of the journal Heart.
The long-term benefits of nurse home visits to low-income, unmarried women during pregnancy and the early years of their children's lives endure for many years after the program of home visitation ends, according to two newly published studies appearing in today's issue of the Journal of the American Medical Association. These benefits include less use of welfare, fewer childhood injuries, less child abuse, and fewer arrests among the women.
A new computing concept--patterned after successful space missions--may soon help UD researchers complete the blueprint for a supercomputer 1 million times more powerful than the most advanced PC now on the market. Capable of processing 1 million billion commands or "floating point operations" per second, the world's first "petaflops" machine may feature superconducting microprocessors and 3-D holographic data storage.

Everybody says she would quit her job if she won the lottery. But you also hear stories about people who keep their jobs and enjoy their wealth on weekends. What's the reality? A recent survey of nearly 900 mangement professionals found that 39 percent would stop working completely if they had enough money, 35 percent would continue working--if they could change jobs--and only 26 percent would keep the jobs they have.

(San Diego) -- For the second year, The College of Business Administration at San Diego State University has been named one of the "25 Best Business Schools for Entrepreneurs," according to the September issue of SUCCESS magazine.
Small businesses are more likely than large employers to be guilty of discriminatory hiring practices where black job seekers are concerned, according to a study by a Michigan State University economist. The study of some 3,000 employers in four major U.S. cities indicates that small businesses are much less likely to hire blacks than are larger businesses.
Hopelessness is a downer for the heart, according to a study that appears in this month's American Heart Association journal Arteriosclerosis, Thrombosis and Vascular Biology. The four-year study of 942 middle-aged men links hopelessness -- defined as feeling like a failure or having an uncertain future -- to a faster progression of atherosclerosis.
With more than two million teeth knocked out every year, mouth injuries are claiming teeth, fracturing jaws and even causing concussions. The American Dental Association (ADA) reports that many of these injuries are sports related and could be prevented by simply wearing a mouthguard.
Most dental patients with prosthetic (artificial) joints will not have to take antibiotics before going to the dentist's office for routine treatments, according to new guidelines published in the July issue of the Journal of the American Dental Association (JADA). (Historically, the orthopedic surgeons and other physicians have recommended premedication of patients with prosthetic joints to prevent possible infections.)
New research indicates dental x-rays may help detect patients who are at risk of stroke, according to a study published in the July issue of the Journal of the American Dental Association (JADA).
An analysis of several infant formulas shows that some have significant potential to cause tooth decay in babies if parents allow the child to sleep with a bottle of formula in their mouth.
New research suggests young children may be getting more fluoride than they need through baby foods, according to a study published in the July issue of the Journal of the American Dental Association (JADA).
Body piercing is becoming more popular these days, and as people run out of body parts to impale, many are turning to the mouth, lips and tongue as suitable places for jewelry. However, according to a case study published in the July issue of the Journal of the American Dental Association (JADA), dentists need to be aware of this growing trend and the risks to patients that oral piercing carries.
The American Dental Association (ADA) is advising parents that they should be aware of but not overly concerned about one part of a warning label the Food and Drug Administration (FDA) now requires on fluoride toothpastes. Beginning April 7, fluoride toothpastes were required to indicate: "If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately."

The new gene, called p73, is deleted in at least one type of cancer and resides in an area of the genome that researchers worldwide have for years scoured for suspected tumor suppressor genes. The findings are reported in the August 22 Cell and are embargoed until Thursday, August 21, 5:00 pm EDT.
