The University of Illinois has created a 2,500 square meter prehistoric domestic compound to teach students how to conduct non-invasive archeogeophysical testing. The site, called CATS, features various archaeological features typical of Eastern and Midwestern Native American cultures of 600 to 2,000 years ago.
A new study by researchers at the University of North Carolina at Chapel Hill found that Russian women and children are not consuming enough iron in their diets. The study, which analyzed data from over 3,000 households, revealed that more than half of the iron consumed is lost due to interactions with other foods.
A new study by Columbia University and NASA finds that the Arctic ozone hole is projected to double in size by 2020, leading to increased skin cancer cases globally. The research models show that greenhouse gases are cooling the stratosphere, causing more ozone depletion.
Sandia National Laboratories has proposed a design for an accelerator, X-1, that aims to achieve high-yield fusion. If funded, the project is expected to reach initial operating capability by 2007 and high-yield fusion by 2010, providing important data for the nation's stockpile stewardship program.
Despite evidence of warfarin's effectiveness, it remains underused to prevent strokes in those with atrial fibrillation. The study found that increased prescriptions from 13% to 40% between 1989 and 1993 did not lead to significant changes in usage from 1993 onwards.
Researchers at the University of Illinois found that microwave-blanched asparagus retains its nutritional value, taste, and texture better than traditionally blanched asparagus. The process involves short exposure to high heat, typically two to five minutes, using a microwave oven.
A new Cornell University study finds that higher taxes on cigarettes will have a statistically insignificant impact on reducing teenage smoking rates. Higher taxes are estimated to reduce the number of new teen-age smokers by less than half a percentage point or two percentage points, respectively.
Exposure to stress during puberty results in abnormal aggressive and submissive behaviors, as well as neurobiological alterations, in hamsters. The study suggests that an imbalance in vasopressin and serotonin brain chemical systems contributes to inappropriate behavior.
Researchers have gained insight into the mechanisms of cell migration by altering a calcium-regulated traffic signal that dictates how cells stick to their environment. This discovery could lead to new treatments for diseases such as cancer invasion and metastasis, as well as inflammatory problems like arthritis.
A large study of 5,106 primary school students found that overweight children had higher blood pressure, total cholesterol, LDL cholesterol, and lower HDL cholesterol levels than their lighter peers. The study also showed that many more children became overweight over time than returned to a healthy weight.
Researchers found that focusing on mastering skills and self-improvement boosts adolescent girls' motivation and reduces dropouts from sports. A mastery-oriented approach can optimize motivation for all participants, leading to a better pool of talent at higher levels.
