Nepalese Researchers Identify Cost-effective Treatment For Drug-resist
New research carried out by researchers in Nepal has shown that a new and affordable drug, gatifloxacin, may be more effective at treating typhoid fever than the drug currently recommended by the World Health Organization. The study, funded by the Wellcome Trust, has implications for the treatment of typhoid particularly in areas where drug resistance is a major problem. The results are published in the June 27 issue of the online, open-access journal PLoS ONE. Nanotechnology Meets Biology And DNA Finds Its Groove
The object of fascination for most is the DNA molecule. But in solution, DNA, the genetic material that hold the detailed instructions for virtually all life, is a twisted knot, looking more like a battered ball of yarn than the famous double helix. To study it,scientists generally are forced to work with collections of molecules floating in solution, and there is no easy way to precisely single out individual molecules for study. Only some like it hot: How birds from different populations react to i
With the help of new radiotelemetry technology, researchers have now succeeded, for the first time, in studying fever in a vertebrate species living in the wild, the North American song sparrow. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Puerto Rico and the Dawn of the Modern Age: Nineteenth- and Early-Twen
"Portrays the early history of the commonwealth of Puerto Rico through first-person accounts, political writings, and histories."Topics include "the land and its resources, relations with Spain, the competition among political parties, reform efforts, and recollections by veterans of the Spanish-American War."Materials date from 1831 through 1929, and most are in Spanish.

The right kind of stress response in the operating room could lead to quicker recovery for patients after knee surgery, according to a new study. The results could be used to develop methods for predicting how well patients will fare after they leave the hospital. Newer, Simpler Fixes Restore Corroded Pipelines
Researchers are taking the guesswork out of repairing corroded oil and gas pipelines. Historically, engineers repairing corroded pipeline segments have not had much guidance in regard to measuring the effectiveness of their choice of repair materials. Hope For Arthritis, Heart Attack, Stroke Relief Found In Unique 'Acid
Acidic conditions such as arthritis causes in joints, tests cells' survival mechanisms. University of Texas Medical Branch-Galveston researchers studied a unique, wide-spread, acid-sensing receptor that protects human cells in pH down to 6 in synovial fluid, well below physiological normal pH7.4. The ability to operate normally in acidic conditions -- or at least survive them -- also could have clinical significance in heart attack, stroke and other low-oxygen episodes that cause reperfusion injury, the researchers believe. Printable sensors for cell phones and other devices?
The cellphone is switched off but immediately springs into action at the point of a finger. It is not necessary to touch the display. This touchless control is made possible by a polymer sensor affixed to the cellphone which, like human skin, reacts to the tiniest fluctuations in temperature and differences in pressure and recognizes the finger as it approaches. The scenario is fictitious at present but could become reality in a few years time. Physicist Sees Terahertz Imaging As Ultimate Defense Against Terrorism
John Federici, PhD, professor, department of physics, New Jersey Institute of Technology (NJIT) and other physicists at NJIT recently received a U.S. Patent for a Teraherz imaging system and method. Since 1995, Terahertz imaging has grown in importance as new and sophisticated devices and equipment have empowered scientists to understand its potential.
