People with prostate cancer currently have several treatment options available to them. But one of the oldest, brachytherapy, is losing popularity with physicians. Without action, the skills needed to perform this effective therapy could be lost.
Some of the most effective modern drugs are complex biological molecules. As their patents expire, drug developers are fashioning copycat versions that could make such therapies cheaper and more broadly available.
Many long-term diseases of the liver lead to scarring, or fibrosis, that restricts the organ’s functions. Evidence that fibrosis can regress has spurred the search for therapies that suppress scar-tissue formation to restore liver health.
Existing treatments bring only temporary relief to people with ulcerative colitis, a common form of inflammatory bowel disease. Insights into the immunobiology of the condition are driving the development of therapies that could lead to prolonged periods of remission.
A bone fracture that fails to heal after initial treatment can lead to prolonged disability. Regenerative therapies might help to restart the bone-healing process, getting the people affected back in action.
Loss of the stem cells that constantly renew the surface of the cornea causes pain and, in some cases, blindness. Advances in transplantation and cell culture are helping to restore vision to even the most severely affected people.
The promises of quantum computation are unique — and so are the challenges. Progress in physics, mathematics, computer science and engineering have brought quantum computers to a point where they start to challenge their classical counterparts.

Ovarian cancer is difficult to treat, largely because tumours are often found late and develop resistance to initial treatment: platinum-based therapy. New approaches promise to break through the platinum barrier.
