Medical science has come a long way from tribal shaman dispensing herbs and roots. Having already cured many diseases and conditions that were once a death sentence, medical researchers continue to strive to help us live longer and healthier lives. Great advances are being made in regrowing damaged organs, turning back our biological clocks, and the big one – finding a cure for cancer.
Traditionally the sex of a blood donor has been considered irrelevant when giving a blood transfusion, but a study is raising concerns suggesting blood transfusions delivered to men using blood from previously pregnant women could increase their risk of dying in the years following the transfusion

Mini lab-grown organs are helpful test subjects for new drugs, but they don’t replicate how drugs affect other parts of the body. Now, researchers at Wake Forest Institute for Regenerative Medicine have combined several of these organ models into one system, to create a detailed “body-on-a-chip."

Imagine if a bandage could release fresh doses of medication over time, or even different types of medication at specific times. Well, researchers from the University of Nebraska-Lincoln, Harvard Medical School and MIT have developed just such a thing … and it could be controlled by a smartphone.

Bacteria are evolving resistance to antibiotics at an alarming rate. One of the main issues is overprescription of antibiotics, and now a new test developed by scientists at Caltech could help doctors quickly prescribe the best type of antibiotic to fight a particular infection.
