A recent study by the University of Arizona has shown that having a dog around children will not cause asthma, and may actually help prevent it. The National Institutes of Health were so impressed with the results of the study that they are investing almost a million dollars into a grant to have the researchers make their results more conclusive.
"Several longitudinal studies have shown that exposure to certain domestic animals, for example, indoor dogs, during a person's early life (even possibly before he or she is born) is associated with strong protection against asthma and asthma-related conditions later in life," Serrine Lau, a member of the research team said.
So if you were hesitant to get a dog because they were afraid their children may develop breathing problems, you may want to reconsider.
Medical dramas like Grey's Anatomy get a lot of things wrong when it comes to the procedures shown on the screen, but unless you're a doctor, you'd probably never notice.
For its latest installment, WIRED's Technique Critique video series—which previously blessed us with a dialect coach's critique of actors' onscreen accents—tackled the accuracy of medical scenes in movies and TV, bringing in Annie Onishi, a general surgery resident at Columbia University, to comment on emergency room and operating scenes from Pulp Fiction, House, Scrubs, and more.
While Onishi breaks down just how inaccurate these shows and movies can be, she makes it clear that Hollywood doesn't always get it wrong. Some shows, including Showtime's historical drama The Knick, garner praise from Onishi for being true-to-life with their medical jargon and operations. And when doctors discuss what music to play during surgery on Scrubs? That's "a tale as old as time in the O.R.," according to Onishi.
Other tropes are very obviously ridiculous, like slapping a patient during CPR and telling them to fight, which we see in a scene from The Abyss. "Rule number one of CPR is: never stop effective chest compressions in order to slap or yell words of encouragement at the patient," Onishi says. "Yelling at a patient or cheering them on has never brought them back to life." And obviously, taking selfies in the operating room in the middle of a grisly operation like the doctors on Grey's Anatomy do would get you fired in real life.
There are plenty of cliché words and phrases we hear over and over on doctor shows, and some are more accurate than others. Asking about a patient's vitals is authentic, according to Onishi, who says it's something doctors are always concerned with. However, yelling "We're losing him!" is simply for added TV drama. "I have never once heard that in my real life," Onishi says.
A book of 10th-century psalms recovered from St. Catherine’s Monastery on Egypt's Sinai Peninsula is an impressive artifact in itself. But the scientists studying this text at the U.S. Department of Energy's SLAC National Accelerator Laboratory at Stanford University were less interested in the surface text than in what was hidden beneath it. As Gizmodo reports, the researchers were able to identify the remains of an ancient Greek medical text on the parchment using high-powered x-rays.
Unlike the Large Hadron Collider in Switzerland, the Stanford Synchrotron Radiation Lightsource (SSRL) used by the scientists is a much simpler and more common type of particle accelerator. In the SSRL, electrons accelerate to just below the speed of light while tracing a many-sided polygon. Using magnets to manipulate the electrons' path, the researchers can produce x-ray beams powerful enough to reveal the hidden histories of ancient documents.
In the case of the 10th-century psalms, the team discovered that the same pages had held an entirely different text written five centuries earlier. The writing was a transcription of the words of the prominent Greek physician Galen, who lived from 130 CE to around 210 CE. His words were recorded on the pages in the ancient Syriac language by an unknown writer a few hundred years after Galen's death.
Several centuries after those words were transcribed, the ink was scraped off by someone else to make room for the psalms. The original text is no longer visible to the naked eye, but by blasting the parchment with x-rays, the scientists can see where the older writing had once marked the page. You can see it below—it's the writing in green.
Now that the researchers know the hidden text is there, their next step will be uncovering as many words as possible. They plan to do this by scanning the book in its entirety, a process that will take 10 hours for each of the 26 pages. Once they've been scanned and studied, the digital files will be shared online.
Particle accelerators are just one tool scientists use to decipher messages that were erased centuries ago. Recently, conservationists at the Library of Congress used multispectral imaging, a method that bounces different wavelengths of light off a page, to reveal the pigments of an old Alexander Hamilton letter someone had scrubbed out.
