Why does post nasal drip cause bad breath
If you grew up in the suburbs, you recognize it immediately: the sweet, sharp smell of someone mowing a lawn or ballfield. As it wafts into your nostrils, it somehow manages to smell exactly like the color green. But what are we really smelling when we inhale that fresh-cut grass scent? And why do we like it so much? Chemically speaking, that classic lawn smell is an airborne mix of carbon-based compounds called green leaf volatiles, or GLVs. Plants often release these molecules when damaged by insects, infections or mechanical forces — like a lawn mower. Plants manufacture slightly different forms of GLVs depending on what's happening to them, said Ian Baldwin, a plant ecologist and founding director of the Max Planck Institute for Chemical Ecology in Jena, Germany. In a 2010 study published in the journal Science, he and colleague Silke Allmann, of the University of Amsterdam, found that tobacco leaves punctured and rubbed with insect saliva released a different bouquet … [Read more...] about Why Does Freshly Cut Grass Smell So Nice?
Little girls are told they're made of sugar and spice and everything nice. At least, according to the popular nursery rhyme. But, one Alabama mother is showing they can be whatever they want to be— by capturing stunning photos of girls as both princesses and athletes. Photographer Heather Mitchell told CBS News she was at her 8-year-old daughter Paislee's softball practice in late March and making casual conversation with another mom. Mitchell said to the mother she hoped "Paislee learned to love the game, because she's athletic."The other mother's reaction took her by surprise. Mitchell said she told her that Paislee is "not athletic, she's a girly girl." Later that night Mitchell couldn't sleep, bothered by the comment. "I was thinking why does she have to choose between being girly and athletic," said the photographer. "Why can't she just be both without the judgement of it?" The next morning, she told her husband she needed to shoot some photos of her daughter in … [Read more...] about “Why does she have to choose”: Mom’s photos show girls they can love sports — and be girly
Earth's atmosphere is enormous, so far reaching that it even affects the International Space Station's route. But how did this giant gaseous envelope form? That is, why does Earth have an atmosphere? In short, our atmosphere is here because of gravity. When Earth formed, about 4.5 billion years ago, the molten planet barely had an atmosphere. But as the world cooled, its atmosphere formed, largely from gases spewed out of volcanoes, according to the Smithsonian Environmental Research Center (SERC). This ancient atmosphere was very different from today's; it had hydrogen sulfide, methane and 10 to 200 times as much carbon dioxide as the modern atmosphere does, according to SERC. [Infographic: Earth's Atmosphere Top to Bottom] "We believe the Earth started out with an atmosphere a bit like [that of] Venus, with nitrogen, carbon dioxide, maybe methane," said Jeremy Frey, a professor of physical chemistry at the University of Southampton in the United Kingdom. "Life then began … [Read more...] about Why Does Earth Have an Atmosphere?
