It goes without saying that the heart is an important organ, but it’s difficult to study how it reacts to diseases and medications. Researchers at Harvard have now grown a model of a human left ventricle that spontaneously beats, marking a substantial step towards engineering entire hearts for more accurate testing of new treatments. Traditionally, […]

  Full of antioxidants and vitamins, tea is pretty good for you, and green tea extracts have even been used as effective carriers for cancer drugs. New research led by Swansea University has found a novel way to wring more health benefits out of the stuff, by making quantum dots from tea leaves and using them to […]

The earlier cancer is detected, the better the outlook for the patient. Unfortunately, cancer is a crafty foe and does a good job of hiding its presence until it’s too late. Now, researchers at ETH Zurich have developed a novel early warning system for four common types of cancer. An implant keeps watch for elevated […]

Nanoparticle drug delivery systems are a hot area in medical research at the moment. The ability to engineer particles that can enter a human body and transport a drug directly to a targeted cell is revolutionizing how medicine is delivered. A team of researchers from the University of Illinois has now created a new nanoparticle […]

There are some paraplegic rats that are now able to walk again, or that are at least coming close to doing so, and it’s thanks to human stem cells. The cells essentially helped bridge a gap that scientists had introduced in the animals’ spinal cords. Led by Dr. Shulamit Levenberg, a team from the Technion-Israel […]
