Young Africans Suffering Advanced HIV Disease From Delayed Diagnosis
A new study suggests the effects of long-standing, undiagnosed HIV infection are hanging over a generation of adolescents in Zimbabwe, causing organ damage, chronic ill health, stunted growth, and other problems. The research demonstrates the need to reduce barriers to early testing and admission to care for these adolescents. It appears in the March 15 issue of Clinical Infectious Diseases, currently available online. Study Confirms That Stents Releasing Medication Help Keep Heart Bypass
A study confirms that medication-releasing stents reduce scar tissue formation in saphenous vein grafts, and patients receiving them have lower short-term incidence of vessel re-narrowing, heart attack and death. The study is described in the November 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions. Driving Abilities Not Impaired By Moderate, Long-Term Pain Medication
Opioid pain relievers, such as morphine and other narcotics, carry warning labels urging patients not to drive or operate heavy machinery during use. In addition, drivers under the influence of pain medication are typically subjected to the same laws and penalties as drivers under the influence of alcohol. And yet, in a recent, preliminary study researchers found no difference in the "driving skills and reaction times"of patients taking morphine compared to non-medicated drivers. Drinking Without Food May Set You Up For High Blood Pressure
During this season to be jolly, when alcohol flows more freely than usual, a new study alerts drinkers that a habit of drinking outside of meals may be setting them up for high blood pressure. 'Retrospective Rubber'Remembers Its Old Identities
Researchers have developed a shape-memory rubber that may enable applications as diverse as biomedical implants, conformal face-masks, self-sealing sutures, and "smart"labels. The material forms a new class of shape-memory polymers, which are materials that can be stretched to a new shape and will stay in that form until heated, at which time they revert to their initial shape. Rejection Sets Off Alarms For Folks With Low Self-esteem
Few can tolerate such romantic or professional rebuffs as "It's not you, it's me"and "we regret to inform you that your application was not successful."But while a healthy dose of self-esteem can absorb the shock of rejection, poor self-esteem can trigger the primal fight-or-flight response, according to a new study in the journal Psychological Science. Study Provides New Estimates Of The Causes Of Child Mortality Worldwid
Seventy-three percent of the 10.6 million child deaths worldwide each year are the result of six causes: pneumonia, diarrhea, malaria, neonatal sepsis, preterm delivery and asphyxia at birth. Researchers at the Johns Hopkins Bloomberg School of Public Health and the World Health Organization (WHO) have developed the most accurate estimates to date of the causes of death of children under age 5. Australia Day

This 2005 government report considers changes in college textbook prices and what factors have contributed to these changes (such as CD-ROMs and other instructional supplements). The report notes that "in the last two decades, college textbook prices have increased at twice the rate of inflation but have followed close behind tuition increases."Includes a summary and the full text, with diagrams and charts.

In a stunning example of evolution at work, scientists have now found that changes in a single gene can produce major changes in the skeletal armor of fish living in the wild. The surprising results, announced in the March 25, 2005, issue of journal Science, bring new data to long-standing debates about how evolution occurs in natural habitats.
