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. Chemical Warfare Ravages Mental Health Of Iranian Civilians
Iranian civilians exposed to high-intensity warfare and chemical weapons are experiencing significantly higher levels of psychological distress compared to those exposed to low-intensity warfare but not chemical weapons, researchers at Yale School of Medicine report in the August 2 issue of the Journal of the American Medical Association devoted to the theme of violence and human rights. Tuberculosis Patients Can Reduce Transmissability By Inhaling Interfer
A new study has found that patients with cavitary pulmonary tuberculosis receiving anti-TB medications supplemented with nebulized interferon-gamma have fewer bacilli in the lungs and less inflammation, thereby reducing the transmissibility of tuberculosis in the early phase of treatment. Creating Males With Female Sex Chromosomes: Brain Gene Flicks The Swit
Researchers have discovered a way of creating a male mouse without a Y chromosome by manipulating a single gene in the developing foetus. Scripps Research Scientists Solve Structure Of A Critical Innate Immun
Scientists at The Scripps Research Institute have solved the structure of a crucial human immune system molecule called TLR3, an acronym for Toll-like receptor three. In an upcoming issue of the journal Science, the protein is described as a large horseshoe-shaped coil composed of 23 leucine-rich repeats (LRRs). Teens and Technology: Youth Are Leading the Transition to a Fully Wire
This July 2005 report finds that the "number of teenagers using the internet has grown 24%in the past four years and 87%of those between the ages of 12 and 17 are online,"and that "the variety of technologies that teens use to support their communication, research, and entertainment desires has grown."Includes the text of the report and the underlying questionnaire. From the Pew Internet &American Life Project. Precision Breakthrough: Have Scientists Drilled The World's Smallest H
Experts at Cardiff University have developed machinery so sophisticated that they can drill a hole narrower than a human hair. Such precision has potentially major benefits in medical and electronic engineering. The experts at the University's multi-award-winning Manufacturing Engineering Centre, are drilling holes as small as 22 microns (0.022 mm) in stainless steel and other materials. The human hair varies between 80 microns (0.08 mm) down to 50 microns (0.05 mm) in thickness. Patients With Mild Cushing Syndrome May Benefit From Adrenalectomy
Patients with a mild form of Cushing syndrome, a metabolic disorder caused by adrenal tumors, showed substantial clinical improvement after adrenalectomy. The study is the largest series of surgical outcomes reported in patients with subclinical Cushing syndrome to date. Helping Out A High-temperature Superconductor
Researchers at the US Department of Energy's Brookhaven National Laboratory have discovered a way to significantly increase the amount of electric current carried by a high-temperature superconductor, a material that conducts electricity with no resistance. This is an important step in the drive to create superconductor-based electric and power-delivery devices, such as power transmission lines, motors, and generators. The results are explained in the September 12, 2005, online edition of Applied Physics Letters. Obese Older Women May Be More Prone To Frailty
Obesity is associated with frailty in obese older women, according to a recent study published in the Journal of the American Geriatrics Society. Frailty, a condition that occurs in some older people, is characterized by physiological vulnerability and increased risk of falls, personal dependency, and mortality.
