For the past decade, scientists have been toying with the notion of encapsulating medicine in microscopic balls.
These so-called nanospheres could travel inside the body to hard-to-reach places, like the brain or the inside of a tumor. One problem researchers face is how to build these nanospheres, because you'd have to make them out of even smaller nanoparticles.
Outsiders might be unfamiliar with the U.K.'s National Health Service, but Brits love it so much that they devoted part of opening ceremonies at the 2012 London Olympics to the NHS.

We're just catching up with our U.K. reading list, so we're a bit late with this one. But it's worth noting that as of Oct. 1, England's National Health Service is providing treatment for HIV free of charge to visitors from overseas.
When a case of the potentially lethal H5N1 bird flu was found in British poultry in 2007, Dutch farmers were told to keep their poultry away from wild birds by closing off outdoor areas with wire mesh.

What was supposed to be a 60-day moratorium on certain experiments involving lab-altered bird flu has now lasted more than eight months. And there's no clear end in sight.
Researchers still disagree on how to best manage the risks posed by mutant forms of highly pathogenic H5N1 bird flu. The altered viruses are contagious between ferrets, which are the lab stand-in for humans. The fear is that these germs could potentially cause a deadly flu pandemic in people if they ever escaped the lab.
Matt Langione, a subject in the study, reads Jane Austen's <em>Mansfield Park</em>. Results from the study suggest that blood flow in the brain differs during leisurely and critical reading activities.
At a recent academic conference, Michigan State University professor Natalie Phillips stole a glance around the room. A speaker was talking but the audience was fidgety. Some people were conferring among themselves, or reading notes. One person had dozed off.

The two scientists who won this year's Nobel Prize in Physiology or Medicine discovered that cells in our body have the remarkable ability to reinvent themselves. They found that every cell in the human body, from our skin and bones to our heart and brain, can be coaxed into forming any other cell.
