Further proof that humans grossly underestimate all other non-human lifeforms. Parrots reason like three year old children, mice feel empathy, elephants grieve, birds hold funerals for their dead, and now this.
And yet we won't hesitate to deforest natural habitats for yet more highways and ugly low density housing. And scientists continue to use animals for all kinds of shockingly inhumane experiments. Over 19 million animals are killed each year in research in the US alone, and that's not counting mice.
Even house pets are stolen and used for animal testing.
Surely we are the smartest animal on the planet (smart enough to rationalize anything), but isn't it more important we be compassionate?
Ah, Hacker News, I always underestimate you. As I was reading the article, I was thinking to myself, there is no way someone can turn this into a negative, cynical, crabby top comment. Boy, how wrong I was.
Not a single mention of anything in the article, just a bunch of loud complaining about how humans aren't living the way some random guy on the internet thinks they should.

We aren't the only species on the planet that engages in genocide of other species. Plenty of animals, large and small, are predators of other animals as well as habitat destroyers. Heck, I wouldn't be surprised if we someday find an animal that performs tests on other animals (other than us, that is). In nature, it is every species for itself, it is like that extreme form of capitalism that libertarians craze after.
It is egotistical to think that we some how exist outside of our ecosystem, with god like choices to make. Nature will throw things back into balance one way or the other, likely to our detriment.
Natural selection is quite greedy in general: consume resources, or be consumed as a resource! We've grown rich enough to think a bit more forward, which is where conservation comes in, but to think that any of those animals are less selfish than us is crazy.
<…> Even on clear moonless nights, many beetles still manage to orientate along straight paths. This led us to hypothesize that dung beetles exploit the starry sky for orientation, a feat that has, to our knowledge, never been demonstrated in an insect. Here, we show that dung beetles transport their dung balls along straight paths under a starlit sky but lose this ability under overcast conditions. In a planetarium, the beetles orientate equally well when rolling under a full starlit sky as when only the Milky Way is present. The use of this bidirectional celestial cue for orientation has been proposed for vertebrates, spiders, and insects, but never proven. This finding represents the first convincing demonstration for the use of the starry sky for orientation in insects and provides the first documented use of the Milky Way for orientation in the animal kingdom.
It's been known for year that some birds navigate using stars (see Stephen Emlen's research). What is different here is that an insect is doing it and using the "stripe of light" that is the milky way, not individual stars.
