In 1900, German physician Paul Ehrlich came up with the idea of a “magic bullet.” The concept was to inject a patient with smart particles capable of finding, recognizing, and treating disease. Medical science has pursued the magic bullet ever since. Russian researchers from the Moscow Institute of Physics and Technology and Prokhorov General Physics… Read more

Injectable nanoparticles that convert sound waves, which can easily penetrate into the brain, into light, have been developed by Stanford researchers[1]. Optogenetics, a tool for controlling neurons with light, has given neuroscientists the ability to flip brain cells on and off more or less at will, revolutionizing neuroscience. Yet the technique faces a fundamental challenge… Read more

New nanoparticles and nanoclusters dubbed “superballs” offer more control to optogenetics. Optogenetics is a technique that uses light to control cells within living tissue. The biological technique controls cells in tissues genetically modified for light sensitivity. Drawbacks are that the light can activate several genes at once and that it must penetrate deeply to be… Read more

A UCLA-led research team has developed a sprayed gel embedded with immune-boosting drugs that could help cancer tumour recurrence after surgery. Many people who are diagnosed with cancer will undergo some type of surgery to treat their disease — almost 95 percent of people with early-diagnosed breast cancer will require surgery and it’s often the… Read more

Osteoarthritis, a disease that causes severe joint pain, affects more than 20 million people in the United States. Some drug treatments can help alleviate the pain, but there are no treatments that can reverse or slow the cartilage breakdown associated with the disease. In an advance that could improve the treatment options available for osteoarthritis… Read more
