One of the very real problems that oncologists have when treating patients with chemotherapy is something called multi-drug resistance. That means that, even though at first the cancer cells are killed by the drugs, after a while they become immune to them. This happens in many cancers. And it's due to several different proteins that cancers make that leap to multi-drug resistance. Now a new study is showing that at least in breast cancers there might be a very simple and safe way to stop cancers from making these proteins. If true, this would lead to much better results especially in patients with metastatic cancers. 

As more research sheds light on the dangers of a sedentary lifestyle, you may have heard the quip "sitting is the new smoking." While I don't think sitting for hours at a time is quite as harmful as pulling known carcinogens directly into your lungs, I'm glad that our insufficient activity levels are starting to get some attention. And some solutions. I'm particularly glad to see that some of these solutions are targeting children, setting them on the path for good health for life. But don't let these results fool you. They're just as applicable for adults.

There are few things worse than spending hours on a long flight only to spend half your trip sick with a bug you picked up on the plane. Although you may be more likely to think of jet lag as the major downside of intercontinental air travel, it's very common for travelers to end up with a cold or even the flu after a long flight as well. Fortunately, research conducted last year at Griffith University in Queensland, Australia, has identified a helpful step you can take to keep this from happening to you.
