Morsels for the mind – 26/7/2013
Every day we provide you with #SixIncredibleThingsBeforeBreakfast to nibble away at. Here you can fill your brain with the most intellectually stimulating “amuse bouches” from the past week – a veritable smorgasbord for the cranium. They’re all here for you to load up your plate – this week’s “Morsels for the mind”. Enjoy!
Feather, fur & fin – birds, beasts, fishes, and the things they do
Super shrew! If there was one beastie that captured attention this week, it was a remarkable shrew. No need for backup here, this critter has massive vertebrae that can carry the weight of the world. Great coverage by Becky Crew, Rich Johnston, Kelly Servick, and Melissa Hogenboom.
Cool for cats. Cheetahs don’t overheat when they sprint.

Pet peeve. Web-based videos of an endangered animal don’t necessarily educate. More likely to create a desire to have it as a pet.
Catastrophic cashmere. Making the cloth threatens rare big cat and native ungulates.
Unnatural selection. The conflict one feels when taking sides in nature doing its thing. In this case, jays versus a quail fledgling. A wonderful reflection by Chris Clarke.

Never ending story. Veg-eating dinosaurs replaced teeth at an amazing rate during their lifetimes. Sometimes as quick as every 14 days.
Quite a tail to tell. Complete, articulated hadrosaur tail has just one thing missing – the rest of the hadrosaur.
Reality bites. Sabretooth left a nasty mark in a hominid skull.
Big mouth strikes again. Comparing sabretoothed cats with sabretoothed marsupials.
Mammoth undertaking. Did sabretooth cats bring down giant pachyderms?

The curious moonlight. If you were sleepless in Seattle, it may have been a full moon. It’s a sleep wrecker. This was discovered using old data by co-authors who “thought of it after a drink in a local bar one evening at full moon”. Awesome.
Waisting the night away. Increased girth could be due to decreased sleep.
