Morsels for the mind – 5/7/2013
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
What’s in a name? A wonderful rumination on taxonomy & individual animal consciousness, by Brandon Keim.
A nose for newborns. They smell like what their moms ate.
All hear this. Convergent evolution in bats and whales.
Have you herd? A single horse genome gets the “meh” treatment. Great stuff by Erika Check Hayden.
Getting it together. Both group size and environment shape social learning in lemurs. A great exploration of the evolution of socialisation by Krystal D’Costa.
Not so black and white. Determining whether a new orca group is also a new species is not so easy.
And they all lived happily ever after? Nope, these otter twins have a grim tale.
Whales of discord. As superbly illustrated by Kate Whittington: the whaling debate is a classic clash of culture and science. It has created some interesting outcomes: UN judges compare Japan’s whaling activities to…wait for it..Darwin’s Beagle voyage and the human genome project. Yes, really. Here’s the antidote: Seven, sound, cetacean-scrutinising schemes. The schemes are, by the way, not whaling. It’s important, as evidence suggests that military sonar is taking a toll – linked to strandings. No flukey coincidence.
“If you run, you will only die tired.” How to survive a lion attack. Might come in useful.
Fantastic fallout. Radiation from nuclear blasts could thwart ivory poachers.
Getting a head in life? Might head transplants be possible? Some folks are not convinced that we are there yet.
Getting to the bottom of things. Passing gas: easier standing up or lying down? The science!
No more monkey business? As captive chimp research winds down, should we now take a better look at other primates?
Some nerve! Special neurons provide birds with GPS.
The eyes have it. Convergent evolution of vision, including squid.

End game. If there is a tail to be pulled, corvids will pull it!
Behaving shellfishly. The snail that builds it shell with the shells of others.
Mobile homes. Invasive land snails provide shells for marine hermit crabs.
Where is every body? Amazing maps account for all species of mammals, birds and amphibians.
Colourful characters. The evolutionary emergence of snake colour morphs in non-venomous snakes to mimic venomous ones.
Back to the birthplace. Fish navigate to where they were born using a sun-based compass.
Saw unseen. The numbers of sawfish have dwindled by 90% in the last decades. Dire.
Disappearing act. Amazing octopus camouflage. Must be seen to be believed.
Cut little suckers. An octopus hatchling.
No guts, no gory? Lionfish’s impressive eating also makes it a formidable invasive. Great story by Christie Wilcox.

Get on up. Even dinosaurs crawled before they walked.
Marvellous mariners. Mesosaurs took to the seas.
Fine feathered friends. Birds may shed light on the world in which Homo floresiensis lived.
Gone, but not forgotten. Exploring the dodo. Great story by Henry Nicholls about remains in a natural history museum.
The hungry caterpillar…killed the dinosaur. Maybe not the best bedtime hypothesis, but darn interesting even if ultimately incorrect.
Microscopic marvels – smaller than the eye can see, but big in action – bacteria, fungi and viruses
Microbe-made moods? How our gut bacteria might be shaping our behaviour. Jane Foster has put together an excellent piece here.
A black mark in history. Revisiting The Plague. Delightfully gruesome stuff by Annelie Wendeberg.
Magnificent mushroom makers. The cool stuff fungi do.
Fungi’s firm footing. We’ve got fungi all over us, but nowhere are they more diverse than on our feet.
Double downside. Gut microbes of obese mice spur liver cancer.
A real shot in the arm. Rabies antidote could save 55000 people per year.
Molecular machinery – the toils of the macromolecules of life – nucleic acids and proteins (and others)
Spectacularly small. Tiny genomes tell a much bigger tale about evolution. Beautiful piece by Carl Zimmer.
A matter of taste. Testes have taste receptors. Tasticles? Indeed.
Art of arteries. The genes that shape blood vessel formation.
Into the fold. Depending on protein folding, different extent of Parkinson’s disease severity.
Kept in check. How jumping genes are made to settle down.

Up, up, and away. Balloons might be the next big thing in astronomy.
Forces of nature – big-ticket items – cosmology, ecology, evolution, physics, mathematics, chemistry
