Animals get a hard rap when it comes to cleaning. They trigger allergies, leave fuzz everywhere, and gleefully destroy furniture. Now it looks like having them around might serve some long term good — especially if you have young children.
Though asthma is caused by many things, there are no mistaking the symptoms: your airways are swollen shut, and you can barely breathe. Now a new study of thousands of people reveals how asthma starts. Often, it's with second-hand smoke.
It sounds like the plot of a Troma flick, but yes, your lungs contain taste receptors. When these receptors encounter bitter compounds, they open up your airways — this discovery could radically improve the treatment of lung conditions like asthma.
