My theory about the itty-bitty iPod shuffle is that Apple made it so small so that people will constantly be losing them, and buying replacements.

But besides the over-the-top portability, the new shuffle has another advantage: it can be swallowed.

Also in today’s links: cute ancient creatures, a link between anorexia and autism, and more.

  • What’s cuter than a well-preserved baby mammoth? A seal with legs. Researchers have found the fossilized skeleton of a creature with the long tail and body of an otter, webbed feet and the legs of a land creature, and a skull like those of seals, sea lions and walruses.
  • Some health professionals and researchers see anorexia as being related in some ways to autism, even calling for the eating disorder to be placed in the category of autism spectrum disorders. The similarities — including rigid, inflexible thinking — could help people develop new ways of treating anorexia and bulimia.
  • Researchers have had some success treating drug-resistant tumors using treatments chosen after a genetic screening of the patient, a finding that could point toward more genetically personalized medicine.
  • The surprise player at the box office is science and nature documentaries, which can pull in the big bucks for relatively low cost. While “I Love You, Man” has grossed $65.3 million domestically, the documentary “Space Station 3D” has hit $78.5 million.
