Preserving A 460-Year-Old Wreck An international team of researchers has analysed the sulphur and iron composition in the wooden timbers of the Mary Rose, an English warship wrecked in 1545, which was salvaged two decades ago. The team used synchrotron X-rays from the Stanford Synchrotron Radiation Laboratory (USA) and the European Synchrotron Radiation Facility (France) in order to determine the chemical state of the surprisingly large quantities of sulphur and iron found in the ship. These new results provide insight to the state of this historic vessel and should aid preservation efforts. Explosive Discovery On Genetically Engineered Tobacco Plant Tobacco may be bad for human health, but a new study reports that a genetically engineered tobacco plant may be very good for the environment. It shows promise for cleaning up soil contaminated with TNT, a widely used military explosive. New Challenges For Diagnosis Of Bacterial Sexually Transmitted Infecti This year cases of sexually transmitted infections have risen by 2 percent in the UK, in spite of a small drop in the incidence of syphilis and gonorrhea. How Well Do Dogs See At Night? Dogs see a lot better than humans do at night. Dogs have many adaptations for low-light vision. A larger pupil lets in more light. The center of the retina has more of the light-sensitive cells (rods), which work better in dim light than the color-detecting cones. Officials Simulate Bioterrorist Attack To Test Disease Surveillance Public health officials gathered this week to demonstrate the utility of the National Capital Region Disease Surveillance Network, an early warning system for bioterrorist attacks. [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." Stanford Snake Venom Study Shows That Certain Cells May Eliminate Pois Researchers at the Stanford University School of Medicine have shown that the immune system really does side with the victim, at least in four kinds of venom that were used in their experiments. Sugar Coated Proteins Seal In A Memory Of Diabetes, Research Shows Researchers at the University of Warwick's Warwick Medical School have uncovered a process that locks the body's metabolism in a diabetic state after only relatively limited exposure to high glucose levels. HP Chair Tries to Quell Uproar Claiming innocence of the sleazy tactics investigators used to gather information on company board members and reporters, HP's Patricia Dun tries to keep her job. Fruit Flies Prefer Fizzy Drinks That fruit fly hovering over your kitchen counter may be attracted to more than the bananas that are going brown; it may also want a sip of your carbonated water. Scientists have found that fruit flies detect and are attracted to the taste of carbonated water, such as water found on rotting fruits containing yeast. This finding raises the question of whether taste in humans may be more complex than scientists have thought.
