In cancer treatments such as chemotherapy, hundreds of thousands of cancerous cells are killed off. But if even one of these cells has a unique mutation, it can survive the treatment and start to multiply, giving rise to a set of more drug-resistant cells. Researchers at the Salk Institute in California have now gained new insights into what exactly is causing these variations in the cells, suggesting there may in fact be a way of switching off the mechanism and improving treatment effectiveness.

There may be new hope for people who have lost some of their hearing due to exposure to loud noises, or simply due to aging. Scientists from the University of Michigan and Harvard University have restored hearing in mice, by getting them to create more of a protein within their ears. Read More
In today's installment of "How 3D Printing is Changing Healthcare Forever," a Massachusetts-based medical device company is forging new ground in knee replacement surgery. A combination of CT imaging, modeling software and 3D printing technology is enabling ConforMIS to offer implants tailored specifically to each patient. The development could help avoid complications that often follow the procedure, such as pain arising from instability of the joint. Read More
While the idea of cruising around in a 3D-printed car and munching on 3D-printed chocolate before returning to a 3D-printed home sure is nice, no industry is poised to benefit from this burgeoning technology in quite the way that medicine is. Replacing cancerous vertebra, delivering cancer-fighting drugs and assisting in spinal fusion surgery are just some of the examples we've covered here at Gizmag. The latest groundbreaking treatment involves an Indian cancer patient, who has had his upper jaw replaced with the help of 3D printing. Read More
One complication that can arise from a heart attack is the formation of scar tissue, which can the harden organ's walls and impede its ability to pump blood. This is caused by fibroblast cells which move to replace damaged muscle with the scar tissue. New research conducted at the University of North Carolina's (UNC) School of Medicine suggests these cells could be converted to endothelial cells which actually assist in recovery, potentially minimizing the damage caused during a heart attack.

Conventional open surgery on the brain involves drilling openings in the skull through which to access the gray matter. But what if the part of the brain needing to be accessed is located at the bottom of the brain as is the case with treating severe epileptic seizures? Generally it means more drilling. Now engineers at Vanderbilt University have developed a surgical robot that uses an alternative point of entry – the cheek. Read More
Many of us drink green tea for its wonderful health benefits, including proven antioxidant, antimicrobial, anti-aging and anti-cancer properties. Now, researchers in Singapore have taken its cancer-fighting properties to the next level, developing a green tea-based nanocarrier that encapsulates cancer-killing drugs. It is the first time green tea has been used to deliver drugs to cancer cells, with promising results. Animal studies show far more effective tumor reduction than use of the drug alone while significantly reducing the accumulation of drugs in other organs. Read More
Our bodies have evolved to be pretty good at dealing with incursions by foreign objects and bacteria. Usually, that's a positive thing, but it can spell trouble for medical devices, such as replacement joints, cardiac implants and dialysis machines, which increase the risk of blood clots and bacterial infection. Now researchers at Harvard University have developed a surface coating that smooths the way for medical devices to do their job inside the human body. Read More
Stem cell researchers at Harvard University have devised a method for creating large quantities of human insulin-producing beta cells, which could soon lead to a cure for type 1 diabetes as well as a new treatment for type 2 diabetes. The cells are currently being trialled in animals and non-human primates with hopes human trials could take place in the near future.. Read More
Robotic prostheses have advanced greatly in the past decade, in terms of both cost and capability. Unfortunately, the standard electrode-over-skin method of control makes many of them unreliable and restricts their functionality, meaning that a number of recipients of these devices commonly reject them as a result. However, a Swedish man has recently celebrated a milestone in robotic prostheses by taking advantage of an osseointegrated (bone-anchored), thought-controlled, implant system in his daily life for more than a year and a half.
