Pumping a body full of celldestroying chemicals sounds like a bad idea, but that’s what chemotherapy entails. The side effects of intravenous chemo for liver cancer, the third deadliest cancer in men, usually necessitate a four-day hospital stay with each treatment. As doctors try to target the chemicals by injecting high doses into an artery that feeds the tumor, the bloodstream inevitably carries them into the rest of the body. It’s an imprecise and painful process, but a plastic bead called a QuadraSphere could make it less so.
Optical signals could be used instead of electrical signals to stimulate cells in the body, scientists say. In a new study, researchers at the University of Utah used brief, low-power light pulses to control the actions of inner-ear cells, potentially leading to therapies that let those with auditory disorders hear the light.
Mashing web-based virtual microscopy and a massive multi-touch display surface, Finnish researchers have created a new interface for laboratory science that allows researchers to pan and zoom around a microscope sample via a tabletop or wall-mounted touchscreen, zooming in so close that sub-cellular details can be seen.
A 25-year-old father from Fort Worth, Texas, received a new face in a 15-hour procedure last week, Brigham and Women’s Hospital announced Monday. Dallas Wiens is the first American to receive a full facial transplant.

One of the toughest things about Type 1 diabetes – a chronic, incurable autoimmune disease – is that once it begins to develop, there's no way to stop it. Slowly but surely, your immune system will kill off the cells in your pancreas that produce insulin, a crucial hormone that allows you to absorb the energy (in the form of glucose) from your food. The process can take years, but the end result is always the same: you'll be entirely dependent on injections of artificial insulin to stay alive. Even though it's now possible to predict with more than 75 percent accuracy whether someone will develop Type 1 within the next five years, there's nothing to do with that information but wait.
But a new trial, launched through the National Institutes of Health's Type 1 Diabetes Trial Net, may change that.
Rather than bringing people into the lab, researchers at MIT are putting tiny labs into people via a tiny implantable capsule that can track the growth of a tumor or detect heart-deterioration or even silent heart attacks from inside the body.
Using a combination of microscopy methods, Harvard researchers have untangled part of the circuitry of the cerebral cortex, illuminating brain connections in 3-D. A new neural circuit model will allow researchers to crawl through the individual connections in a neural network.
A new type of endoscope with a super-small camera on its end could yield cheap, disposable scopes for peering inside your body. The camera is about the size of a grain of kosher salt, and its designers say it's the smallest camera ever.
A potential new cancer treatment could be as simple as taking a swig of some genetically modified salmonella. The bug, famous for forcing food recalls and making people sick, could be weaponized to fight tumor cells.
Human trials are already under way at the University of Minnesota, where researchers have successfully tested salmonella-led tumor control in mice.
