Morsels for the mind – 2/8/2013
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
“Monogamy is a problem.” Well, it is for evolutionary biologists when hypotheses compete, and this week there were two: paternal protection versus layabout lovers. It was a topic that garnered great coverage by Seth Borenstein, Carl Zimmer, Josh Howgego, and Kit Opie (who also authored one of the two papers in the primary literature).
Here among the cats. No words needed to capture the magnificence of lions. Stunning.
Tigers’ tremendous travels. Searching for mates takes big cats all over the place. And that’s not a good thing.
Rights of passage. Atlantic right whale mating grounds may have been identified.
Getting older every day. Other animals show signs of ageing too. Each in their own way.
Newly discovered lemur is unbearably cute. That is all.
“A map of the cat sir?” A wonderful piece by Christina Agapakis on the incomparable Richard Feynman and his take on biology.
Mews of the day. What are cats telling us? We probably don’t know.
Ruff guide to language. How does learn words.
Berry nice. Wolves bring back bears’ berries.
Back-scratching bears. Best. Thing. Ever. So said everyone.
Bulging biceps. That’s what female kangaroos find attractive. Speaking of finding things attractive…
No so fond of the fans. It turns out that peahens aren’t so into a peacock’s fanning tail. Instead peahens like leggy lovers –focusing on his legs and the base of his tail. This got great coverage by Greg Miller, Susan Milius, Victoria Gill, and Robin Anne Smith.
On thin ice. The impact of melting ice floes on baby harp seals. A rocky road ahead.
You won’t like him after he’s had a couple. Seagulls get “drunk” on flying ants.
Marvellously macabre. Beautiful butcher birds.
What the flock? Pigeon hierarchy changes when they take flight.
What’s going on up there? How birds get it on.

“We’re set up for catastrophe.” We ignore plant diseases at our peril. Ed Yong masterfully stitches together farming ants, modern agriculture, crop domestication and plant pathology in one brilliant piece. Read of the week.
Naked lady smut. Not what you’re thinking. It’s important (as per Ed Yong’s piece above). John Platt uncovers a timely tale.
Orange you glad there’s genetic modification? A simply spectacular treatment of the GMO discussions as it relates to saving the orange crop from a devastating disease. Amy Harmon’s phenomenal talents as a journalist are in full play here – dealing with a sensitive topic in a balanced manner, completely infused with the best science.
“There’s a romantic notion of environmentalism…and then there’s actual environmentalism.” Amy Maxmen does a wonderful job of covering the science and the very human-scale problem of generating and deploying GM crops. A beautiful complement to Amy Harmon’s piece above.
Keep off the grass. We should forgo having lawns.
A good angle on life. How plants do geometry.

Sometimes the romance runs thin. The thing about space travel is that the human body is sometime pretty icky.
Spectacular sprites. Nature’s fireworks.
Forces of nature – big-ticket items – cosmology, ecology, evolution, physics, mathematics, chemistry
“It’s a story we share with labradoodles & meteorites, stones & running brooks.” An ode to the journey taken by atoms in the cosmos. Lovely writing by Matthew Francis. Speaking of which:
