Living for the city. Urban living is changing the brains and behaviours of animals. Absolutely genius reporting on this fascinating story by Brandon Keim, Carl Zimmer and Rachel Nuwer. Reads of the week.

Getting a grip. Thumbs provide us with a means by which to grasp the wonder of evolution.

“Gasp at what evolution has wrought.” On the discovery, and rediscovery, of species.

Doing like they otter. Sea otters sustain ecosystem function even in the face of pollution. Ed Yong and Suzi Gage pull the threads of this story together perfectly.

In the lap of the dogs. Canine slurping is an acrobatic feat. Julie Hecht dishes it up.

Dogged determination. Some dogs are incredibly intelligent. Chaser leaves most of those in the dust. Dan Nosowitz’s feature on the “world’s smartest dog” is a must-read for dog lovers (and those interested in non-human animal smarts).

Howls for pals. Wolves call to maintain social groups. Shout outs to Virginia Morell, Melissa Hogenboom, and Arielle Duhaime-Ross for their coverage of canine calls.

Stroke of genius. Apes swim using strokes not dog paddle. Carrie Arnold, Kelly Servick, and Marc Lallanilla got into the swim of things.

Not so black and white? Is breeding pandas really worth it?

Aloha! Whales call all depths of Hawaii’s seas home.

The right stuff. Finding the right whale breeding ground was no mere fluke.

A noble prize? Orcas shouldn’t be in captivity, but not because they’re “noble”. Excellent case made by Jeffrey Bloomer.

Alarming find. Salamanders respond to worm alarm. Fascinating stuff by Anne-Marie Hodge.

Homeward bound. Zoo reintroductions helping bring hellbender back from the brink.

The eyes have it. Damselfish have bigger fake eyes, smaller real eyes when predators lurk. As always, beautifully told tale by Elizabeth Preston.

At arm’s length. Severed octopus arms act on their own.

All the right moves. Deep-sea squid attract prey with feeble but wavy arms. Becky Crew, Daniel Cressey, & Ed Yong dangled this enticing story.

On the trail of the snail. Keeping apace of a vector of deadly dog disease. Interesting story by Matt McGrath.

Developing at a snail’s pace. Because it’s a snail.

Hanging on by a thread. In the mussel’s case, a remarkable thread.

****

Fossil finds – organisms of times past – dinosaurs and beyond

Clutch call. The challenge of determining just how many eggs dinosaurs laid.

Getting a head of ourselves. Three skulls led to three species names. Actually just one species.

Big fish story. While scaled back from original estimates, this denizen of the deep from160M years ago was still the largest ever. Robin McKie and Brian Switek share tales of the one that went away.

Dinosaurs of yore. Twenty years on, Jurassic Park continues to inform and misinform.

Microscopic marvels – smaller than the eye can see, but big in action – bacteria, fungi and viruses

Going retro. The astonishing story of how a retrovirus flew to birds from mammals, fabulously explained by Ed Yong. Read of the week.

Molecular machinery – the toils of the macromolecules of life – nucleic acids and proteins (and others) – from molecules to cells to organs to organisms (including genetics & genomics)

Thanks for the memories. There’s a protein that helps retain (or lose) memories as you age. It’s something to remember.

Out of Africa? Genetics tracks ancient treks back into the big continent.

Let’s talk. How cells communicate. Nice explainer.

Spinning out parts. Weaving human tissue replacements, spider style.

Fluid dynamics. The “right” salmon sperm is chosen by ovarian fluid.

Not so sweet? The quantity of sugar in some foods is ridiculous. Here’s the science.

Mything the point. Separating science from myth related to high fructose syrup and diabetes. Excellent.

A matter of time. And space. And space time. Brilliant piece by Zeeya Merali on the latest hypotheses explaining the dimensions of our universe.

It elementary. There’s a claim of pretty solid evidence for element 115 out there. Ununpentium. Hmm.

Knotty by nature. Liquid crystals tied in knots using mini Möbius strip.

It’s complicated? When it comes to mathematics, it doesn’t have to be. Adam Kucharski makes it all add up.

Fished in? Did guppies really rapidly evolve cognitive skills? Some folks aren’t hooked.
