In 2008, some scientists proposed that cows can sense magnetism and actually line up in fields along Earth's magnetic lines. It's the sort of paper that everybody in the media wants to talk about for, roughly, two weeks ... and then never mention again.
But that's not how science works. One research paper does not an unquestionable fact make. Luckily Discover's Discoblog has been kind enough to update us on the current state of magnetic cow research. Shorter version: This issue is far from settled, with a second research team attempting to poke holes in the original study. Nevertheless, outside researchers say, the original findings still look strong. There is evidence that herds of cows stand along magnetic lines, and fail to stand along those lines in the presence of magnetic-field distorting high-voltage power lines. Whether this is absolutely the case and, if so, why, remains a bit of a mystery. Needs moar research.
... an analysis of Google Earth images by another team finds no such lining up. In a back-and-forth over the last year in scientific journals, the first team reanalyzed the second’s data and said that half of the images were useless, since they were near high-voltage power lines or contained hay bales or sheep instead of cows. Plus, the first team points out that the second team looked at single cows within herds instead of herds as a whole, and it’s pretty clear at this point that animals in herds and flocks aren’t operating as independent entities. The second team retorts that their images were too okay to use, and the first team may have been looking at the wrong pictures.

Scientists discovered this new species of “glass frog” in Ecuador’s Amazon lowlands. Hyalinobatrachium yaku’s belly is so transparent that you can clearly see its kidneys, bladder, and beating heart. From Science News: Yaku means “water” in Kichwa, a language spoken in Ecuador and parts of Peru where H. yaku may also live. Glass frogs, like […]

Apple released this lovely new commercial featuring Carl Sagan reading from his magnificent 1994 book Pale Blue Dot: A Vision of the Human Future in Space, now available as an audiobook. This surprising partnership spurred Adweek to interview my friend Ann Druyan, Sagan’s wife, collaborator, and creative director of the Voyager Golden Record, about being […]
Learning a new language will give your resume an upgrade, sure, but it will also provide a huge cognitive boost for mental tasks outside of translation and conversation. Bilingual brains have been shown to be better at handling multiple concurrent tasks, and gaining fluency in a new tongue is an amazing way to improve memory, […]
