The flu reminds us that as social animals, pathogens can kill both individuals and large segments of our population. A study sheds some light on how ants, social insects, cope with infections that endanger their colony.
Evidence indicates that dogs can become infected with human-adapted influenza strains, making this incredibly concerning. When two different influenza strains infect the same host, the viruses can swap genes, a process known as genetic reassortment. This can produce devastating influenza pandemics.
Illnesses and deaths from hepatitis A are making headlines daily. And last year, it was hepatitis C. And what about hepatitis B? Let's decipher the hepatitis alphabet soup, and spell out the differences.
Chronic wasting disease, which is a condition nearly identical to mad cow disease, has been detected in deer all across the United States.

The nutrients that typically come to mind in connection with osteoporosis are calcium and vitamin D. But if a mouse study is translatable to humans, we may have to add dietary fiber to that list. Fiber is broken down by some gut bacteria to form short chain fatty acids that prevent bone breakdown.
C-diff is a bacterium that causes a life-threatening infection. Though the bacterium can infect healthy individuals, it is of particular concern to those who are hospitalized or are taking antibiotics.
Treatment advances are not easy to come by, especially in some hard-to-treat cancers like brain and triple negative breast cancer. New research, however, shows that infection with a virus could be key in making a promising treatment applicable to some cancers that were previously resistant.
Society has been blind to the secret suffering of many children. What appears to the rest of us as a cute albeit slightly annoying phase is actually a serious mental illness: Dinosaur Obsession Disorder.
