...treatment sounds harsh, but the findings confirm what many pediatric dermatologists have seen anecdotally for years. The theory is that the antimicrobial properties of bleach help relieve symptoms of eczema not by acting directly on that skin condition, but by improving children's skin infections of staph bacteria - a common co-occurrence that exacerbates the irritating symptoms of eczema...
...study, researchers followed 31 children between the ages of 6 months and 17 years, who had both conditions: atopic dermatitis, the most common form of childhood eczema, which affects 17% of the school-aged population, as well as a co-infection of Staphylococcus aureus. Although antibiotics are typically used successfully to combat such staph infections, the emergence of drug-resistant MRSA (or methicillin-resistant Staphylococcus aureus) has physicians increasingly wary of overusing the medicines...
When a scientific principle is common knowledge even in grammar school, you know it has long since crossed the line from theory to established fact. That's the case with dinosaur extinction. Some 65 million years ago - as we've all come to know - an asteroid struck the earth, sending up a cloud that blocked the sun and cooled the planet. That, in turn, wiped out the dinosaurs and made way for the rise of mammals. The suddenness with which so many species vanished after that time always suggested a single cataclysmic event, and the 1978 discovery...
...dinosaurs, after all, left more than the Chicxulub crater as its calling card. At the same 65-million-year depth, the geologic record reveals that a thin layer of iridium was deposited pretty much everywhere in the world. Iridium is an element that's rare on Earth but common in asteroids, and a fine global dusting of the stuff is precisely what you'd expect to find if an asteroid struck the ground, vaporized on impact and eventually rained its remains back down. Below that iridium layer, the fossil record shows that a riot of species was thriving; above...
