One of the worlds most imminent and fatal viruses, Ebola is quickly contaminating West Africa. Ebola is caused by an Ebola virus, and can have many symptoms including fevers, strep throat, body pain, and migraines. There is a very limited plan of treatment for Ebola and there are five different strains.
The spread of the Ebola virus is the most miniscule move that starts at the molecular level attacking the host cell and infecting the body. Most infections are thought as transmitted by direct contact. Contact such as needles, secretions from a carrier, and semen. The chicanery of the transmission of an Ebola virus has caused the infection of the doctors treating Ebola.
The most widespread outbreak of Ebola has struck Guinea. Guinea is in western Africa and Ebola has also spread to Sierra Leone & Liberia. The World Health Organization (WHO) has reported a death toll of 826 people from 1440 patients.
Ebola is one of the most deadly viruses that we face today. Many people are suffering from fevers, migraines, and muscle aching pain. West African patients are dying from the sub par containment and poor bedside manner. However American scientists have cured two doctors infected with Ebola.
Symmetry is an inherent part of development. As an embryo, an organism’s brain and spinal cord, like the rest of its body, organize themselves into left and right halves as they grow. But a certain set of nerve cells do something unusual: they cross from one side to the other. New research in mice…
Diagnosis by Light: Shrinking Chemical Labs Onto Optical Fibers
Lab-on-fiber sensors could monitor the environment and hunt for disease inside your body
Imagine an entire laboratory that fits inside a case the size of a tablet computer. The lab would include an instrument for reading out results and an array of attachable microsize probes for detecting molecules in a fluid sample, such as blood or saliva. Each probe could be used to diagnose one of many different diseases and health conditions and could be replaced for just a few cents.
This scenario is by no means a pipe dream. The key to achieving it will be optical glass fibers—more or less the same as the ones that already span the globe, ferrying voluminous streams of data and voice traffic at unmatchable speeds. Their tiny diameter, dirt-cheap cost, and huge information-carrying capacity make these fibers ideal platforms for inexpensive, high-quality chemical sensors.
We call this technology a lab on fiber. Beyond being an affordable alternative to a traditional laboratory, it could take on tasks not possible now. For instance, it could be snaked inside industrial machines to ensure product quality and test for leaks. It could monitor waterways and waste systems, survey the oceans, or warn against chemical warfare. One day, maybe as soon as a decade from now, it could be injected into humans to look for disease or study the metabolism of drugs inside the body.

This technology is really remarkable it’s the innovation in the medical field that will ultimately change the way doctors diagnose patients. However, how this technology is implemented in the future may also take a toll on the health care system as we know it. People won’t go to a Radiologist any more if this technology can identify Glioblastoma multiforme without expert analysis. Technology becomes more affordable as time goes on. Can this new form of scanning mean the end of many professional specializations? Only time will tell.
By screening over 1,000 different types of molecules, scientists have managed to identify a compound that can literally blow up tumor cells belonging to the most aggressive form of brain cancer —…
Sounds like people may have a chance to live longer lives thanks to this new drug. Unbelievable, medical science is really making a difference in the lives of people diagnosed with Glioblastoma multiforme.
Scientists have uncovered how inflammation and lack of oxygen conspire to cause brain damage in conditions such as stroke and Alzheimer’s disease.
Hopefully this research can lead to a better understanding of Alzheimer’s Disease.
