And you thought that regular pill bottles were hard to open ... a new
overdose-proof medication dispenser developed by a team of mechanical
engineering students at Johns Hopkins University can't be opened even
with the help of a hammer or drill. It does, however, deliver the proper
dosage at the proper time, as long as the patient uses its built-in
As it stands, there's not a whole lot we know about pain. Where a tissue or blood sample can be drawn and studied, our nervous system comprising different kinds of cells running signals through complex piping around the body presents a difficult task for scientific research. But a new study details a technique that turns blood cells into different nerve cells, promising to improve our understanding of why things itch or burn. By extension, it is hoped that it could lead to new forms of pain relief that do away with unwanted side effects such as sleepiness or loss of concentration.
A new type of medical device could one day put the minds of chronic pain sufferers at ease by distributing the body's own natural pain relief signals at just the right time. Developed at Linköping University in Sweden, the tiny "ion pump" is made from organic electronics and could be implanted in patients, serving to cut off pain signals in the spinal chord before they make their way to the brain.
