Many people feel that stem cell research is morally repugnant on the grounds that researchers intentionally abort fetuses and take their cells for evil purposes. The fact of the matter is that scientists don’t need to take stem cells from aborted fetuses because they...
How subarachnoid hemorrhage is diagnosed
By: Alicia M Prater PhD
A subarachnoid hemorrhage is a type of bleeding in the skull. The vessels in the brain can sometimes rupture, causing blood to pool in the brain cavity. When this rupture, or hemorrhage, forces blood into the subarachnoid space between the brain and the thin tissues...

The military has had an interest in medicine since the first cavemen fought over a good cave. For most of the history of man on this planet, more soldiers died of disease than from wounds of any sort. As we conquered disease, due largely to...
How a brain hemorrhage is diagnosed
By: Alicia M Prater PhD
A brain hemorrhage occurs when blood vessels that feed the brain and its surrounding tissues are damaged, leaking blood into the surrounding tissue or cavities. An intracerebral hemorrhage is when the blood leaks directly into the brain, and a subarachnoid hemorrhage is when it leaks...
History of the discovery of anesthesia
By: Julie Helms
When one thinks of the discoverer of the polio vaccine—Jonas Salk jumps to mind, the discoverer of germs leading to disease—Louis Pasteur; but who comes to mind for one of the most important medical discoveries ever: anesthesia...for most people, no one. The...

Imagine that you have the ability to feel an object, its geometry, texture, and hardness, without actually physically touching the object. Suppose you are feeling the object over a very long distance. Is this possible? There is research in the works developing such capabilities. The...

The science of cryonics won’t make you immortal but it does offer the chance for your frozen corpse to be reanimated. There are no guarantees that if you choose to have your freshly deceased body frozen that you will ever be brought back to...
An overview of neurocryopreservation as a cryonic technique
By: Stephen Poulitsis
The idea of frozen corpses being revived and cured of whatever disease killed them is a science which captures the imagination. Cryonics is supported by many renowned scientists who work in related fields of research, many of whom believe that the possibility of reviving those...
