The leading cause of death in children worldwide, pneumonia kills an estimated 1.4 million children under the age of five every year - more than AIDS, malaria, and tuberculosis combined. Now, a team of scientists at the University of Melbourne, Australia has created “StethoCloud”, a cloud-based app for smartphones that can help diagnose conditions like pneumonia without the need for a doctor.
Six years ago, Dr. John Khier of Boston Children’s Hospital began investigating the idea of using injectable oxygen on patients whose lungs were incapacitated or whose airways were blocked. He was prompted to do so after a young girl that he was caring for passed away – she succumbed to a brain injury, which resulted when severe pneumonia caused her lungs to stop working properly, which in turn caused her blood oxygen levels to drop too low. Now, Khier is reporting that his team has injected gas-filled microparticles into the bloodstreams of oxygen-deprived lab animals, successfully raising their oxygen levels back to normal levels within seconds.
Scientists at Singapore's Nanyang Technological University (NTU) have created a "magnetic-like" coating that traps and destroys 99 percent of the bacteria and fungi that it encounters. The antibacterial coating
has been shown to be effective against superbugs like Staphylococcus aureus and is already being used in the manufacture of contact lenses. As well as finding numerous biomedical and household applications, the research could lead to new wound treatments and even be used to target bacterial infections inside the body without the use of conventional antibiotics.
